Abortion surveillance--United States, 1998.

PROBLEM/CONDITION: In 1969, CDC began abortion surveillance to document the number and characteristics of women obtaining legal induced abortions, to monitor unintended pregnancy, and to assist efforts to identify and reduce preventable causes of morbidity and mortality associated with abortions. REPORTING PERIOD COVERED: This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States in 1998. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by occurrence. From 1973 to 1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998, CDC compiled abortion data from only 48 reporting areas; Alaska, California, New Hampshire, and Oklahoma did not report. RESULTS: In 1998, 884,273 legal induced abortions were reported to CDC, representing a 2% decrease from the 900,171 legal induced abortions reported by the same 48 reporting areas for 1997. The abortion ratio, defined as the number of abortions per 1,000 live births, was 264, compared with 274 in 1997 (for the same 48 areas); the abortion rate for these 48 areas was 17 per 1,000 women aged 15-44 years for both 1997 and 1998. The availability of information about characteristics of women who obtained an abortion in 1998 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions by state is reported by state of residence and state of occurrence; characteristics of women obtaining abortions in 1998 are reported by state of occurrence. Women undergoing an abortion were likely to be young (i.e., age < 25 years), white, and unmarried; slightly more than one half were obtaining an abortion for the first time. Of all abortions for which gestational age was reported, 56% were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. Overall, 19% of abortions were performed at the earliest weeks of gestation (< or = 6 weeks), 18% at 7 weeks, and 19% at 8 weeks. From 1992 (when this information was first collected) through 1998, an increasing percentage of abortions were performed at the very early weeks of gestation. Few abortions were provided after 15 weeks of gestation; 4% were obtained at 16-20 weeks, and 1.4% were obtained at > or = 21 weeks. A total of 24 reporting areas submitted information stating that they performed medical (nonsurgical) procedures (two of these areas categorized medical abortions with "other" procedures), making up < 1% of all procedures reported from all states. From 1993 through 1997 (years for which data have not been published previously and the most recent years for which such data are available), 36 women died as a result of complications from known legal induced abortion, and three deaths were associated with known illegal abortion. The annual case-fatality rate of legal induced abortion ranged from 0.3 to 0.8 abortion-related deaths per 100,000 reported legal induced abortions. INTERPRETATION: From 1990 through 1995, the number of abortions declined each year; in 1996, the number increased slightly, but in 1997, it declined to its lowest level since 1978. In 1998, the number of abortions continued to decrease when comparing the 48 reporting areas. In 1997, as in previous years, deaths related to legal induced abortions occurred rarely. PUBLIC HEALTH ACTIONS TAKEN: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed and efforts to prevent unintended pregnancy can be evaluated.

Abortion surveillance--United States, 1993 and 1994.

CONDITION: From 1991 through 1994, the number of legal induced abortions reported to CDC declined each year by < or =5% from the number reported for the preceding year. REPORTING PERIOD COVERED: This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States during 1993 and 1994. This analysis also includes recently reported abortion-related deaths that occurred during 1991. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. RESULTS: In 1993, 1,330,414 legal abortions were reported to CDC, representing a 2.1% decrease from the number reported for 1992; in 1994, 1,267,415 abortions were reported, representing a 4.7% decrease from the number for 1993. In 1993 and 1994, the abortion ratio was 334 and 321 legal induced abortions per 1,000 live births, respectively. In 1993, the abortion rate was 22 per 1,000 women aged 15-44 years; in 1994, this rate declined to 21 per 1,000 women. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most were obtaining an abortion for the first time. More than half of all abortions (52%-54%) were performed at < or =8 weeks of gestation, and approximately 88% were before 13 weeks. Approximately 15%-16% of abortions were performed at < or =6 weeks of gestation, 16% were performed at 7 weeks, and 22% at 8 weeks. Younger women (i.e., women aged < or =19 years) were more likely to obtain abortions later in pregnancy than were older women. In 1991, 12 women died as a result of induced abortion: 11 of these deaths were related to legal abortion and one to illegal abortion. During 1991, the case-fatality rate of legal induced abortion was 0.8 abortion-related deaths per 100,000 legal induced abortions. INTERPRETATION: Since 1990, the number of abortions has declined each year. Since 1987, the abortion-to-live-birth ratio also has declined; in 1994, it was the lowest recorded since 1977. This decrease in the abortion ratio reflected the lower proportion of pregnant women who obtained an induced abortion. As in previous years, deaths related to legal induced abortions occurred rarely (i.e., approximately one death per 100,000 legal induced abortions). ACTIONS TAKEN: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed, efforts to prevent unintended pregnancy can be evaluated, and the preventable causes of morbidity and mortality associated with abortions can be identified and reduced.

Abortion surveillance--United States, 1997.

PROBLEM/CONDITION: In 1969, CDC began abortion surveillance to document the number and characteristics of women obtaining legal induced abortions, to monitor unintended pregnancy, and to assist efforts to identify and reduce preventable causes of morbidity and mortality associated with abortions. REPORTING PERIOD COVERED: This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States in 1997. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state where the abortion occurred. The data are received from 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. RESULTS: In 1997, a total of 1,186,039 legal abortions were reported to CDC, representing a 3% decrease from the number reported for 1996. The abortion ratio was 306 legal induced abortions per 1,000 live births, and since 1995, the abortion rate has remained at 20 per 1,000 women aged 15-44 years. The availability of information about characteristics of women who obtained an abortion in 1997 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions by state is reported by state of residence and state of occurrence; characteristics of women obtaining abortions in 1997 are reported by state of occurrence. Women who were undergoing an abortion were more likely to be young (i.e., aged < 25 years), white, and unmarried; approximately one half were obtaining an abortion for the first time. More than one half of all abortions for which gestational age was reported (55%) were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. Overall, 18% of abortions were performed at the earliest weeks of gestation (< or = 6 weeks), 18% at 7 weeks of gestation, and 20% at 8 weeks of gestation. From 1992 through 1997, increases have occurred in the percentage of abortions performed at the very early weeks of gestation. Few abortions were provided after 15 weeks of gestation--4% of abortions were obtained at 16-20 weeks, and 1.4% were obtained at > or = 21 weeks. A total of 19 reporting areas submitted information regarding abortions performed by medical (nonsurgical) procedures, comprising < 1% of procedures reported by all states. Younger women (i.e., aged < or = 24 years) were more likely to obtain abortions later in pregnancy than were older women. INTERPRETATION: From 1990 through 1995, the number of abortions declined each year; in 1996, the number increased slightly, and in 1997, the number of abortions in the United States declined to it lowest level since 1978. PUBLIC HEALTH ACTIONS: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed and efforts to prevent unintended pregnancy can be evaluated.

Abortion surveillance--United States, 1999.

PROBLEM/CONDITION: CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions and to monitor unintended pregnancy. REPORTING PERIOD COVERED: This report summarizes and describes data reported to CDC regarding legal induced abortions obtained in the United States in 1999. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state or area of occurrence. From 1973 through 1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. Beginning in 1998, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these areas were not estimated. The availability of data regarding the characteristics of women who obtained an abortion in 1999 varied by state and by the number of states reporting each characteristic. The total number of legal induced abortions is reported by state of residence and also by state of occurrence for most areas; characteristics of women obtaining abortions in 1999 are reported by state of occurrence. RESULTS: A total of 861,789 legal induced abortions were reported to CDC for 1999, representing a 2.5% decrease from the 884,273 legal induced abortions reported by the same 48 reporting areas for 1998. The abortion ratio, defined as the number of abortions per 1,000 live births, was 256 in 1999, compared with 264 reported for 1998; the abortion rate for these 48 reporting areas was 17 per 1,000 women aged 15-44 years for 1999, the same as in 1997 and 1998. The highest percentages of abortions were reported for women aged < 25 years, women who were white, and unmarried women; slightly more than half were obtaining an abortion for the first time. Fifty-eight percent of all abortions for which gestational age was reported were performed at < or = 8 weeks of gestation, and 88% were performed before 13 weeks. From 1992 (when these data were first collected) through 1999, increases have occurred in the percentage of abortions performed at < or = 6 weeks of gestation. Few abortions were provided after 15 weeks of gestation; 4.3% were obtained at 16-20 weeks and 1.5% were obtained at > or = 21 weeks. A total of 27 reporting areas submitted data stating that they performed medical (nonsurgical) procedures (two of these areas categorized medical abortions with "other" procedures), making up < 1.0% of all procedures reported from all reporting areas. In 1998 (for which data have not been published previously and the most recent year for which such data are available), nine women died as a result of complications from known legal induced abortion; no deaths were associated with known illegal abortion. INTERPRETATION: From 1990 through 1997, the number of legal induced abortions gradually declined. In 1998 and in 1999, the number of abortions continued to decrease when comparing the same 48 reporting areas. In 1998, as in previous years, deaths related to legal induced abortions occurred rarely. PUBLIC HEALTH ACTION: Abortion surveillance in the United States should continue so that trends and characteristics of women who obtain legal induced abortions can be examined and efforts to prevent unintended pregnancy can be enhanced.

Abortion surveillance--United States, 2001.

PROBLEM/CONDITION: CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. REPORTING PERIOD COVERED: This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2001. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these states were not estimated. In 2000 and 2001, Oklahoma again reported these data, increasing the number of reporting areas to 49. RESULTS: A total of 853,485 legal induced abortions were reported to CDC for 2001 from 49 reporting areas, representing a 0.5% decrease from the 857,475 legal induced abortions reported by the same 49 reporting areas for 2000. The abortion ratio, defined as the number of abortions per 1,000 live births, was 246 in 2001, compared with 245 reported for 2000. This represents a 0.4% increase in the abortion ratio. The abortion rate was 16 per 1,000 women aged 15-44 years for 2001, the same as for 2000. For both the 48 and 49 reporting areas, the abortion rate remained relatively constant during 1997-2001. The highest percentages of reported abortions were for women who were unmarried (82%), white (55%) and aged <25 years (52%). Of all abortions for which gestational age was reported, 59% were performed at < or =8 weeks' gestation and 88% at <13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2001, steady increases have occurred in the percentage of abortions performed at < or =6 weeks' gestation. A limited number of abortions were obtained at >15 weeks' gestation, including 4.3% at 16-20 weeks and 1.4% at > or =21 weeks. A total of 35 reporting areas submitted data stating that they performed medical (nonsurgical) procedures, making up 2.9% of all reported procedures from the 45 areas with adequate reporting on type of procedure. In 2000 (the most recent year for which data are available), 11 women died as a result of complications from known legal induced abortion. No deaths were associated with known illegal abortion. INTERPRETATION: During 1990-1997, the number of legal induced abortions gradually declined. When the same 48 reporting areas are compared, the number of abortions decreased during 1996-2001. In 2000 and 2001, even with one additional reporting state, the number of abortions declined slightly. In 2000, as in previous years, deaths related to legal induced abortions occurred rarely (less than one death per 100,000 abortions). PUBLIC HEALTH ACTION: Abortion surveillance in the United States continues to provide the data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and to increase understanding of this pregnancy outcome. Policymakers and program planners use these data to improve the health and well-being of women and infants.

PROBLEM/CONDITION: CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. REPORTING PERIOD COVERED: This report summarizes and describes data reported to CDC regarding legal induced abortions obtained in the United States in 2000. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these areas were not estimated. In 2000, Oklahoma again reported these data, increasing the number of reporting areas to 49. RESULTS: A total of 857,475 legal induced abortions were reported to CDC for 2000 from 49 reporting areas, representing a 0.5% decrease from the 861,789 legal induced abortions reported by 48 reporting areas for 1999 and a 1.3% decrease for the same 48 reporting areas that reported in 1999. The abortion ratio, defined as the number of abortions per 1,000 live births, was 246 in 2000 (for the same 48 reporting areas as 1999), compared with 256 reported for 1999. This represents a 3.8% decline in the abortion ratio. The abortion rate (for the same 48 reporting areas as 1999) was 16 per 1,000 women aged 15-44 years for 2000. This was also a 3.8% decrease from the rate reported for procedures performed during 1997-1999 for the same 48 reporting areas. The highest percentages of reported abortions were for women aged <25 years (52%), women who were white (57%), and unmarried women (81%). Fifty-eight percent of all abortions for which gestational age was reported were performed at < or =8 weeks of gestation, and 88% were performed before 13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2000, steady increases have occurred in the percentage of abortions performed at < or =6 weeks of gestation. Few abortions were performed after 15 weeks of gestation; 4.3% were obtained at 16-20 weeks and 1.4% were obtained at > or =21 weeks. A total of 31 reporting areas submitted data stating that they performed medical (nonsurgical) procedures, making up 1.0% of all reported procedures from the 42 areas with adequate reporting on type of procedure. In 1998 and 1999 (the most recent years for which data are available), 14 women died as a result of complications from known legal induced abortion. Ten of these deaths occurred in 1998 and four occurred in 1999; no deaths were associated with known illegal abortion. INTERPRETATION: From 1990 through 1997, the number of legal induced abortions gradually declined. In 1998 and 1999, the number of abortions continued to decrease when comparing the same 48 reporting areas. In 2000, even with one additional reporting state, the number of abortions declined slightly. In 1998 and 1999, as in previous years, deaths related to legal induced abortions occurred rarely (<1 death per 100,000 abortions). PUBLIC HEALTH ACTION: Abortion surveillance in the United States continues to provide data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and for increasing understanding of one additional aspect of the spectrum of pregnancy outcomes. Policy makers and program planners need these data to improve the health and well-being of women and infants.

Abortion surveillance--United States, 1992.

PROBLEM/CONDITION: From 1980 through 1992, the number of legal induced abortions reported to the CDC remained stable, varying each year by < or = 5%. REPORTING PERIOD COVERED: This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States during 1992. This report also includes recently reported abortion-related deaths for 1988-1991 and an update on abortion-related deaths for 1985-1987. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data received from 52 reporting areas (i.e., the 50 states, the District of Columbia, and New York City). RESULTS: In 1992, 1,359,145 abortions were reported--a 2.1% decrease from 1991. The abortion ratio was 335 legal induced abortions per 1,000 live births, and the abortion rate was 23 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and were obtaining an abortion for the first time. More than half (51%) of all abortions were performed at or before the 8th week of gestation, and 87% were before the 13th week. Approximately 14% of abortions were performed at < or = 6 weeks of gestation, 15% were performed at 7 weeks of gestation, and 22% at 8 weeks of gestation. Younger women (i.e., women < or = 19 years of age) were more likely to obtain abortions later in pregnancy than were older women. Sixteen deaths in 1988, 12 deaths in 1989, and five deaths in 1990 were associated with legal induced abortion. The case-fatality rates for 1988, 1989, and 1990, respectively, were 1.2, 0.9, and 0.3 abortion-related deaths per 100,000 legal induced abortions. INTERPRETATION: Since 1980, the number and rate of abortions have remained relatively stable, with only small year-to-year fluctuations of < or = 5%. However, since 1987, the abortion-to-live-birth ratio has declined; in 1992, the abortion ratio was the lowest recorded since 1977. More pregnant women have been opting to carry their pregnancies to term rather than choosing to have an abortion. As in previous years, deaths associated with legal induced abortions occurred rarely (i.e., one or fewer deaths per 100,000 legal induced abortions). ACTIONS TAKEN: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that efforts to prevent unintended pregnancy can be assessed and the preventable causes of morbidity and mortality associated with abortions can be identified and reduced.

Characteristics of women undergoing repeat induced abortion.

BACKGROUND: Although repeat induced abortion is common, data concerning characteristics of women undergoing this procedure are lacking. We conducted this study to identify the characteristics, including history of physical abuse by a male partner and history of sexual abuse, of women who present for repeat induced abortion. METHODS: We surveyed a consecutive series of women presenting for initial or repeat pregnancy termination to a regional provider of abortion services for a wide geographic area in southwestern Ontario between August 1998 and May 1999. Self-reported demographic characteristics, attitudes and practices regarding contraception, history of relationship violence, history of sexual abuse or coercion, and related variables were assessed as potential correlates of repeat induced abortion. We used chi2 tests for linear trend to examine characteristics of women undergoing a first, second, or third or subsequent abortion. We analyzed significant correlates of repeat abortion using stepwise multivariate multinomial logistic regression to identify factors uniquely associated with repeat abortion. RESULTS: Of the 1221 women approached, 1145 (93.8%) consented to participate. Data regarding first versus repeat abortion were available for 1127 women. A total of 68.2%, 23.1% and 8.7% of the women were seeking a first, second, or third or subsequent abortion respectively. Adjusted odds ratios for undergoing repeat versus a first abortion increased significantly with increased age (second abortion: 1.08, 95% confidence interval [CI] 1.04-1.09; third or subsequent abortion: 1.11, 95% CI 1.07-1.15), oral contraceptive use at the time of conception (second abortion: 2.17, 95% CI 1.52-3.09; third or subsequent abortion: 2.60, 95% CI 1.51-4.46), history of physical abuse by a male partner (second abortion: 2.04, 95% CI 1.39-3.01; third or subsequent abortion: 2.78, 95% CI 1.62-4.79), history of sexual abuse or violence (second abortion: 1.58, 95% CI 1.11-2.25; third or subsequent abortion: 2.53, 95% CI 1.50-4.28), history of sexually transmitted disease (second abortion: 1.50, 95% CI 0.98-2.29; third or subsequent abortion: 2.26, 95% CI 1.28-4.02) and being born outside Canada (second abortion: 1.83, 95% CI 1.19-2.79; third or subsequent abortion: 1.75, 95% CI 0.90-3.41). INTERPRETATION: Among other factors, a history of physical or sexual abuse was associated with repeat induced abortion. Presentation for repeat abortion may be an important indication to screen for a current or past history of relationship violence and sexual abuse.

Abortion surveillance--United States, 2003.

PROBLEM/CONDITION: CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. REPORTING PERIOD COVERED: This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2003. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these states were not estimated. During 2000-2002, Oklahoma again reported these data, increasing the number of reporting areas to 49, and for 2003, Alaska again reported and West Virginia did not, maintaining the number of reporting areas at 49. RESULTS: A total of 848,163 legal induced abortions were reported to CDC for 2003 from 49 reporting areas, representing a 0.7% decline from the 854,122 legal induced abortions reported by 49 reporting areas for 2002. The abortion ratio, defined as the number of abortions per 1,000 live births, was 241 in 2003, a decrease from the 246 in 2002. The abortion rate was 16 per 1,000 women aged 15-44 years for 2003, the same as for 2002. For the same 47 reporting areas, the abortion rate remained relatively constant during 1998-2003. During 2001-2002 (the most recent years for which data are available), 15 women died as a result of complications from known legal induced abortion. One death was associated with known illegal abortion. The highest percentages of reported abortions were for women who were unmarried (82%), white (55%), and aged <25 years (51%). Of all abortions for which gestational age was reported, 61% were performed at < or =8 weeks' gestation and 88% at <13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2002, steady increases have occurred in the percentage of abortions performed at < or =6 weeks' gestation, with a slight decline in 2003. A limited number of abortions were obtained at >15 weeks' gestation, including 4.2% at 16--20 weeks and 1.4% at > or =21 weeks. A total of 36 reporting areas submitted data documenting that they performed and enumerated medical (nonsurgical) procedures, making up 8.0% of all known reported procedures from the 45 areas with adequate reporting on type of procedure. INTERPRETATION: During 1990-1997, the number of legal induced abortions gradually declined. When the same 47 reporting areas are compared, the number of abortions decreased during 1996-2001, then slightly increased in 2002 and again decreased in 2003. In 2000 and 2001, even with one additional reporting state, the number of abortions declined slightly, with a minimal increase in 2002 and a further decrease in 2003. In 2001 and 2002, as in the previous years, deaths related to legal induced abortions occurred rarely. PUBLIC HEALTH ACTION: Abortion surveillance in the United States continues to provide the data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and to increase understanding of this pregnancy outcome. Policymakers and program planners use these data to improve the health and well-being of women and infants.

Evaluation of abortions in cattle attributable to neosporosis in selected dairy herds in California.

OBJECTIVE: To estimate the minimum rate of abortion attributable to infection with Neospora sp in selected California dairy herds. DESIGN: Prospective study. ANIMALS: Twenty-six dairy herds containing 19,708 cows were studied. Fourteen herds had a history of abortions attributable to neosporosis, and 12 were herds in which neosporosis had not been identified as a cause of abortions. PROCEDURE: During a 1-year period, all available aborted fetuses were submitted to veterinary diagnostic laboratories to determine the cause of abortion. Reproductive records of cows that aborted were reviewed. RESULTS: Neospora sp infection was the major cause of abortion identified (113/266 abortions, 42.5%). The majority (232/266, 87.2%) of the aborted fetuses were submitted from herds with a history of abortions attributable to neosporosis, and Neospora sp infection was identified as the causative agent in 101 of 232 (43.5%) of the abortions from these herds. Fewer aborted fetuses were submitted from the 12 herds that did not have a history of abortion attributable to Neospora sp; however, neosporosis was confirmed as a cause of abortion in 6 of these 12 herds and was identified as the causative agent in 12 of 34 (35.3%) abortions from these herds. The disease was widespread throughout the state (19/26 herds in our study). Available reproductive histories of cows that had abortions attributed to neosporosis were evaluated, and 4 cows were identified that twice aborted Neospora-infected fetuses. CLINICAL IMPLICATIONS: Abortion attributable to Neospora sp infections can be expected to be a continuing major cause of abortion in dairy herds with a history of neosporosis as well as in dairy herds that have a history of sporadic abortions, but for which Neospora sp infections have not been previously identified as a cause of abortion. Subsequent pregnancies in cows that abort a Neospora sp-infected fetus also are at risk of infection, suggesting that the immunity provided by an initial infection is inadequate to prevent repeat infection or that cows can be persistently infected with Neospora sp.

The impact of Mississippi's mandatory delay law on abortions and births.

CONTEXT: Beginning August 8, 1992, a woman in the state of Mississippi had to wait 24 hours after in-person receipt of state-mandated information regarding abortion and birth complications, fetal development, and alternatives to abortion before an abortion could be performed. OBJECTIVE: To analyze the effect of the law on the abortion and birth rates of Mississippi residents. DESIGN: A retrospective analysis of abortion and birth rates before and after the law in Mississippi as contrasted with abortion and birth rates in 2 comparison states, Georgia and South Carolina. Neither Georgia nor South Carolina enforced a mandatory delay law, but both states began enforcement of parental notification statutes during the study period. PATIENTS: Female residents of reproductive age in Mississippi, Georgia, and South Carolina between 1989 and 1994. MAIN OUTCOME MEASURES: We compared birth rates, abortion rates, the percentage of late abortions, and the percentage of abortions performed outside the state of residence for all women and then by age and race before and after August 1992 among women of Mississippi, Georgia, and South Carolina. RESULTS: We found that rate ratios (RRs) of resident abortion rates (rate after law implementation/rate before law implementation) declined 12% more in Mississippi than in South Carolina (95% confidence interval [CI], 8%-15%) and 14% more in Mississippi than in Georgia (95% CI, 10%-17%) in the 12 months after the law went into effect. Rate ratios for white adults declined 22% more in Mississippi than in South Carolina (95% CI, 17%-27%) and 20% more in Mississippi than in Georgia (95% CI, 15%-25%). Changes among nonwhite adults and white teens were more modest but also statistically significant (P<.05). For all women, RRs of the percentage of abortions performed after 12 weeks' gestation increased 39% more in Mississippi than in either South Carolina or Georgia (P<.05); the increase in the percentage of abortions after 12 weeks' gestation was observed for white and non-white adults (P<.05). We also show that the percentage of abortions performed out of state increased 42% more among women in Mississippi relative to women in South Carolina after the law (95% CI, 34%-50%). CONCLUSION: The timing of the decline in abortion rates in Mississippi, the lack of similar declines in comparison states, the rise in percentage of late abortions and abortions performed out of state and the apparent completeness of abortion reports suggest that Mississippi's mandatory delay statute was responsible for a decline in abortion rates and an increase in abortions performed later in pregnancy among residents of Mississippi. The effect of delay laws in other states will likely depend on whether statutes require 2 separate visits to the abortion provider (ie, clinics, hospitals, or physicians' offices where abortions are performed) and the availability of abortion services.

Abortion surveillance--United States, 1995.

CONDITION: Since 1990 (i.e., the year in which the number of abortions was highest), the annual number of abortions in the United States has decreased by 15%. REPORTING PERIOD COVERED: This report summarizes and reviews information reported to CDC regarding legal induced abortions obtained in the United States during 1995. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. RESULTS: In 1995, a total of 1,210,883 legal abortions were reported to CDC, representing a 4.5% decrease from the number reported for 1994. The abortion ratio was 311 legal induced abortions per 1,000 live births, and the abortion rate was 20 per 1,000 women aged 15-44 years, the lowest ratio and rate recorded since 1975. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most were obtaining an abortion for the first time. Approximately half of all abortions (54%) were performed at < or =8 weeks of gestation, and approximately 88% were performed before 13 weeks. Approximately 16% of abortions were performed at the earliest weeks of gestation (< or =6 weeks), approximately 17% at 7 weeks of gestation, and approximately 21% at 8 weeks of gestation. Few abortions were provided after 15 weeks of gestation -- approximately 4% of abortions were obtained at 16-20 weeks, and 1.4% were obtained at > or =21 weeks. Younger women (i.e., women aged < or =24 years) were more likely to obtain abortions later in pregnancy than were older women. INTERPRETATION: Since 1990, the number of abortions has declined each year. Since 1987, the abortion-to-live-birth ratio has declined; in 1995, it was the lowest recorded since 1975. This decrease in the abortion ratio reflects a trend that a lower proportion of pregnant women obtain induced abortion. ACTIONS TAKEN: The number and characteristics of women who obtain abortions in the United States should continue to be monitored so that trends in induced abortion can be assessed, efforts to prevent unintended pregnancy can be evaluated, and the preventable causes of morbidity and mortality associated with abortions can be identified and reduced.

Characteristics of abortion patients in the United States, 1979 and 1980.

An analysis of the characteristics of women who obtained abortions in 1980 indicates that as in previous years, they were mainly young, white and unmarried. Thirty percent were under age 20 and one percent were under 15; 70 percent were white; 79 percent were unmarried; 58 percent were childless; and 67 percent had had no previous abortions. Ninety-one percent of abortions occurred within the first 12 weeks of gestation, and fewer than one percent occurred past 20 weeks. Between 1977 and 1980, abortion rates rose for unmarried women and white women, but remained about constant or fell among women aged 35 and over, married women and nonwhites. Compared to other Western industrialized countries for which complete abortion data are available, the United States has a high concentration of abortions among younger women and unmarried women. These are the groups toward whom efforts should be directed to increase the prevalence and effectiveness of contraceptive practice. On average, U.S. women aged 35 and over have fewer abortions than women of these ages in the comparison countries, possibly because a larger proportion of U.S. couples who have achieved their desired family size are protected by contraceptive sterilization, the most effective method. According to data from nine states, about 14 percent of U.S. women aged 20 and over obtaining abortions are college graduates, and another 24 percent have attended college. When age differences are taken into account, it appears that women at all educational levels above the eighth grade have abortions at about the same rate. Women aged 20 and over who have had no more than eight years of education have fewer abortions than better educated women. The nonwhite abortion rate is more than twice the white rate because nonwhites have more unintended pregnancies. When faced with an unintended pregnancy, however, nonwhites choose abortion only slightly more often than whites. In spite of their higher abortion rate, nonwhites have a fertility rate 37 percent higher than that of whites. Although hospital abortions are usually more expensive and less convenient than abortions performed in clinics and physician's offices, and the proportion of abortions performed in hospitals has declined, hospitals are still an important source of abortion services for nonwhite women and women with little education, particularly in states which pay for Medicaid abortions. In these states, a large proportion of hospitals offer abortion services, and many low-income women utilize these services.(ABSTRACT TRUNCATED AT 400 WORDS)

Abortion incidence and services in the United States, 1995-1996.

CONTEXT: In the 1980s, the number of abortion providers in the United States began to decline, and more recently, so has the number of abortions performed. Whether the decline in service providers, which was last documented in 1992, is continuing and whether this influences the availability and number of abortions is of public interest. METHODS: In 1997, the Alan Guttmacher Institute conducted its 12th survey of all known abortion providers in the United States. The number and location of abortion providers and abortions were tabulated for 1995 and 1996, and trends were calculated by comparing these data with those from earlier surveys. Limited data were also gathered on types of abortion procedures. RESULTS: Between 1992 and 1996, the number of abortions fell from 1,529,000 to 1,366,000, and the abortion rate decreased from 26 to 23 per 1,000 women aged 15-44. The number of providers fell 14%, to 2,042, with the greatest decline among hospitals and physicians' offices rather than clinics. Eighty-six percent of counties had no known abortion provider, and 32% of women aged 15-44 lived in these counties. Of the country's 320 metropolitan areas, 89 had no known abortion provider, and for an additional 12, fewer than 50 abortions each were reported. Seventy percent of abortions were performed in specialized clinics and only 7% in hospitals. In the first half of 1997, early medical abortions were being offered in about 160 facilities, virtually all of which were also providers of surgical abortions. CONCLUSIONS: While abortion services in some areas of the country have declined since 1992 and many women continue to have limited access to providers, other factors have probably had more influence on the level of abortions performed. Early medical abortion methods are too new to be a measurable factor in abortion access.

Attitudes of inner-city female adolescents toward medical and surgical abortion.

STUDY OBJECTIVE: To explore the attitudes of inner-city minority female adolescents toward medical and surgical abortion to determine if medical abortion methods, which have been shown to be both effective and safe, might have greater appeal than surgical abortion. DESIGN: A cross-sectional, self-administered survey. SETTING: The waiting room of an inner-city hospital-based adolescent clinic. PARTICIPANTS: At total of 157 female adolescents aged 13 to 21 years; Hispanic (56%) and African American (31%). Most (94%) were sexually active, 43% had been pregnant, and 29% had previously had a surgical abortion. OUTCOME MEASURES: An 86-item questionnaire examining attitudes toward medical and surgical abortion safety and impact on future fertility, and pregnancy, abortion, and sexual history. RESULTS: A total of 68% believe that abortion is safe, and 55% believe that having an abortion is better than having an unwanted child. Belief in the safety of abortion was significantly associated with older age and with never having had an abortion. Almost three fourths (72%) believe that having an abortion might impair future fertility either from surgical damage (73%) or "as a punishment for having an abortion" (38%). The majority (72%) believe that "the more abortions you have, the harder it will be to get pregnant in the future." Regardless of personal abortion experience, 51% believe that a medical abortion would be safer than a surgical abortion. A minority (34%) believe that it would be easier to get pregnant after a medical abortion than after a surgical one. CONCLUSIONS: Although most inner-city, minority adolescents believe that abortion is safe, they also believe they risk their future fertility by having an abortion. The availability of medical abortion regimens would greatly influence decisions regarding abortion.

Abortion surveillance--United States, 2002.

PROBLEM/CONDITION: CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. REPORTING PERIOD COVERED: This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2002. DESCRIPTION OF SYSTEM: For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these states were not estimated. For 2000-2002, Oklahoma again reported these data, increasing the number of reporting areas to 49. RESULTS: A total of 854,122 legal induced abortions were reported to CDC for 2002 from 49 reporting areas, representing a 0.1% increase from the 853,485 legal induced abortions reported by the same 49 reporting areas for 2001. The abortion ratio, defined as the number of abortions per 1,000 live births, was 246 in 2002, the same as reported for 2001. The abortion rate was 16 per 1,000 women aged 15-44 years for 2002, the same as for 2001. For the same 48 reporting areas, the abortion rate remained relatively constant during 1997-2002. The highest percentages of reported abortions were for women who were unmarried (82%), white (55%), and aged <25 years (51%). Of all abortions for which gestational age was reported, 60% were performed at < or =8 weeks' gestation and 88% at <13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2002, steady increases have occurred in the percentage of abortions performed at < or =6 weeks' gestation. A limited number of abortions was obtained at >15 weeks' gestation, including 4.1% at 16-20 weeks and 1.4% at > or =21 weeks. A total of 35 reporting areas submitted data stating that they performed and enumerated medical (nonsurgical) procedures, accounting for 5.2% of all known reported procedures from the 45 areas with adequate reporting on type of procedure. INTERPRETATION: During 1990-1997, the number of legal induced abortions gradually declined. When the same 48 reporting areas were compared, the number of abortions decreased during 1996-2001, then slightly increased in 2002. In 2000 and 2001, even with one additional reporting state, the number of abortions declined slightly, with a minimal increase in 2002. PUBLIC HEALTH ACTION: Abortion surveillance in the United States continues to provide the data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and to increase understanding of this pregnancy outcome. Policymakers and program planners use these data to improve the health and well-being of women and infants.

Estimating the efficacy of medical abortion.

Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can change her mind after some period of exposure and opt out. Also, as with medical abortion, a contraceptive can fail, usually with the risk of failure depending heavily on whether or not the woman follows the protocol for that method precisely. Finally, as with medical abortion, medical conditions may arise that necessitate discontinuing use of the contraceptive method. In both cases, these medical conditions are sometimes open to interpretation or subject to the skill, judgment, or experience of the clinician involved. The appropriate information to collect for a multiple decrement life table analysis of medical abortion includes data on compliance with the protocol, timing of the event of interest (abortion) when it is observable, and, because we argue that these should be regarded as events of interest, a typology of any surgical interventions that are conducted during the woman's participation in the study.

Abortion services in the United States, 1984 and 1985.

In 1984 and 1985, the number of abortions, the abortion rate and the abortion ratio stayed at approximately the same levels as in the previous three years. Just under 1.6 million abortions were performed, about three percent of women of reproductive age obtained an abortion, and about 30 percent of pregnancies (excluding those ending in stillbirths and miscarriages) were terminated by abortion. However, the number of abortion providers declined by five percent between 1982 and 1985, and the geographic distribution of abortion services continued to be markedly uneven. Eighty-two percent of all U.S. counties--50 percent of those classified as metropolitan and 91 percent of those classified as nonmetropolitan--lacked an abortion provider in 1985. The long-term trend away from hospital abortions persisted during the period: Eighty-seven percent of the abortions performed in 1985 were done in nonhospital facilities, an increase of five percentage points over the 1982 level. Although abortion clinics constituted only 15 percent of all providers, they were responsible for 60 percent of the procedures performed in 1985. Among all abortion facilities, only 43 percent provided services to women after the 12th week of pregnancy. Abortion clinics were far more likely to offer second-trimester procedures than were other types of abortion providers (75 percent, compared with 13-50 percent). As of mid-1986, charges for a first-trimester nonhospital abortion ranged from $75 to nearly $900. The average amount paid was $213. In 1985, only 39 percent of nonhospital abortion facilities accepted state reimbursement for abortions provided to low-income women, and only 55 percent of facilities offered some reduction in charges to such women.
