Deaths: final data for 1996.

OBJECTIVES: This report presents 1996 data on U.S. deaths and death rates according to demographic and medical characteristics such as age, sex, race, Hispanic origin, marital status, educational attainment, injury at work, State of residence, and cause of death. Trends and patterns in general mortality, life expectancy, and infant and maternal mortality are also described. METHODS: In 1996 a total of 2,314,690 deaths were reported in the United States. This report presents descriptive tabulations of information reported on the death certificates. Death certificates are completed by funeral directors, attending physicians, medical examiners, and coroners. Original records are filed in the state registration offices. Statistical information is compiled into a national data base through the Vital Statistics Cooperative Program of the National Center for Health Statistics, Centers for Disease Control and Prevention. Changes between 1995 and 1996 in death rates and differences in death rates across demographic groups in 1996 are tested for statistical significance. Unless otherwise specified reported differences are statistically significant. RESULTS: The 1996 age-adjusted death rate for the United States decreased, reaching an all-time low of 491.6 deaths per 100,000 standard population, and life expectancy at birth increased by 0.3 years to 76.1 years, a record high. The 15 leading causes of death remained the same as in 1995, although there were changes in the ranking of some causes. Replacing homicide, septicemia became the 12th leading cause of death, and Alzheimer's disease moved from the 14th to the 13th leading cause. For the third consecutive year, the number of homicide deaths dropped, making it the 14th leading cause of death. Mortality declined for all age groups, including persons aged 85 and over. The largest decline in age-adjusted death rates among the leading causes of death was for Human immunodeficiency virus infection, which dropped 28.8 percent in 1996, compared with the previous year. The infant mortality rate declined by 4 percent to a record low of 7.3 infant deaths per 1,000 live births in 1996. Neonatal and postneonatal mortality rates declined for all races combined as well as for postneonatal white infants. Although not statistically significant, mortality rates for white and black neonatal infants and black postneonatal infants also declined. CONCLUSIONS: The overall improvements in general mortality and life expectancy in 1996 continue the long-term downward trend in U.S. mortality. The drop in U.S. infant mortality continues the steady declines of the past four decades.

A study of vital and health statistics of the Kainji Lake Area of Nigeria.

A survey of vital and health statistics, and the evaluation of collection of these data in the registration centres of Kainji Lake Area, are presented. Forty-two per cent of all deaths occurred below 10 years of age, with the largest percentage occurring below 5 years of age. The leading causes of all deaths were malaria, gastro-intestinal disorders and measles. Occurrence of an epidemic was found to be significant to the overall mortality. The role of traditional healers in the control of childhood mortality is discussed. About 34% of the women had married more than once and 56% of the divorces occurred after the first marriage. The causes of divorces were largely due to loss of affection and neglect. The number of deliveries in the hospitals was more than the number of registered births and no death was registered at the centres. A unique system of collection of vital information was suggested for the Kainji Lake Area.

Revised birth and fertility rates for the United States, 2000 and 2001.

OBJECTIVES: This report presents revised birth and fertility rates for 2000 and 2001, based on populations consistent with the April 1, 2000, census. Rates are presented by age, race, and Hispanic origin of mother; by age, race, and Hispanic origin of mother for unmarried women; and by age and race of father. To put the rates for 2000 and 2001 into context, rates are also shown for 1990. METHODS: Populations were produced for the Centers for Disease Control and Prevention's National Center for Health Statistics under a collaborative arrangement with the U.S. Census Bureau. The populations reflect the results of the 2000 census. This census allowed people to report more than one race for themselves and their household members, and also separated the category for Asian or Pacific Islander persons into two groups (Asian; Native Hawaiian or Other Pacific Islander). These changes reflected the Office of Management and Budgets 1997 revisions to the standards for the classification of Federal data on race and ethnicity. Because only one race is currently reported in birth certificate data, the 2000 census populations were "bridged" to the single race categories specified in the Office of Management and Budget's 1977 guidelines for race and ethnic statistics in Federal reporting, which are still in use in the collection of vital statistics data. RESULTS: Population-based birth and fertility rates for 2000 and 2001, based on the 2000 census, are somewhat lower for Hispanics (11 percent for the fertility rate in 2001) and Asian or Pacific Islanders (7 percent) and considerably lower for American Indians (18 percent) than the rates previously published based on populations projected from the 1990 census. Rates for most other population subgroups differ little from those previously published. Because of these patterns, the differentials in fertility among population subgroups remain, but are somewhat reduced. Between 1990 and 2001, teenage birth rates declined, rates for women in their twenties changed little, and rates for women in their thirties and forties rose.

Revised birth and fertility rates for the 1990s and new rates for Hispanic populations, 2000 and 2001: United States.

OBJECTIVES: This report presents revised birth and fertility rates for 1991-99, as well as previously published revised rates for 2000-2001, based on populations consistent with the April 1, 2000, census. Revised rates for Hispanic subgroups (Mexican, Cuban, Puerto Rican, and other Hispanic) are also included in this report. Rates are presented by age, race, and Hispanic origin of mother; by age, race, Hispanic origin, and marital status of mother; by age and race of father; and by age of mother and by State. This report also presents new rates by age and Hispanic origin (subgroups) of mother for 2000 and 2001. The revised rates are compared with previously published rates that used July 1 population estimates based on the 1990 census. METHODS: Populations for most rates were produced for the Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS) under a collaborative arrangement with the U.S. Census Bureau. Populations for teenage subgroups 15-17 and 18-19 years by race and Hispanic subgroups were produced by NCHS. The populations reflect the results of the 2000 census. This census allowed people to report more than one race for themselves and their household members, and also separated the category for Asian or Pacific Islander persons into two groups (Asian and Native Hawaiian or Other Pacific Islander). These changes reflected the Office of Management and Budget's (OMB) 1997 revisions to the standards for the classification of Federal data on race and ethnicity. Because only one race is currently reported in birth certificate data, the 2000 census populations were "bridged" to the single race categories specified in OMB's 1977 guidelines for race and ethnic statistics in Federal reporting, which are still in use in the collection of vital statistics data. RESULTS: Revised population-based birth and fertility rates from 1991 to 1999, based on the 2000 census, are with few exceptions lower than the rates previously published based on populations projected from the 1990 census. As expected, the differences in rates for American Indians, Hispanics, and Asian or Pacific Islanders were considerable. However, revised rates for most other population subgroups (i.e., non-Hispanic whites and blacks) differed little from those previously published. Regardless of the magnitude, the differences between the 2000-based and 1990-based rates progressively diverged through time so that previously published trends were generally retained but lower. Because of this shift, especially for Hispanic women, the differentials in fertility among population subgroups remain, but were somewhat reduced.

An integrated, hospital information system based obstetrical medical record and database.

Described in this paper is the implementation and integration of an obstetrical medical record and database into an existing hospital information system. A unique feature of this system was the integration of existing data captured by the established hospital information systems with the newly implemented obstetrical database to form a complete patient data profile. This complete database integrated data from hospital functions such as demographic data obtained at patient registration, outpatient visits and tests, inpatient admission historical data, tests and procedures, newborn data and miscellaneous data required for birth registration. An important second feature was the utilization of physicians and nurses to enter the obstetrical data. This permitted immediate access to patient data from any hospital information system terminal, immediate retrieval for generating reports, and subsequently, ad hoc queries, statistical analysis and the electronic transfer of birth registration data to the State Vital Statistics Registry.

Birth-cohort phenomenon in the time trends of mortality from ulcerative colitis.

It has been suggested that the mortality trends of ulcerative colitis in England and Wales are shaped by an underlying birth-cohort phenomenon. This pattern implies that exposure to an environmental risk factor early in life plays a crucial role in the development of the disease. The authors tested whether the birth-cohort pattern is unique to British mortality statistics or a common feature of ulcerative colitis in western countries by using the vital statistics from England and Wales, Canada, Scotland, Switzerland, The Netherlands, and the United States. Ulcerative colitis death rates from the six countries were plotted against the periods of death or periods of birth. Mortality from ulcerative colitis increased in successive generations born throughout the second half of the 19th century. It peaked in subjects born between 1880 and 1890 and has declined since then. Strikingly similar patterns were found in the six countries and when women and men were analyzed separately. The birth-cohort pattern indicates that development of ulcerative colitis is strongly influenced by one or several environmental risk factors, which act during a short period early in life. In western countries, exposure to this risk has changed in a similar fashion.

Statistics and public health at CDC.

Since CDC's inception, an important function of the agency has been the compilation, analysis, and interpretation of statistical information to guide actions and policies to improve health. Sources of data include vital statistics records, medical records, personal interviews, telephone and mail surveys, physical examinations, and laboratory testing. Public health surveillance data have been used to characterize the magnitude and distribution of illness and injury; to track health trends; and to develop standard curves, such as growth charts. Beyond the development of appropriate program study designs and analytic methodologies, statisticians have played roles in the development of public health data-collection systems and software to analyze collected data. CDC/ATSDR employs approximately 330 mathematical and health statisticians. They work in each of the four coordinating centers, two coordinating offices, and the National Institute for Occupational Safety and Health.

Oral contraceptive use and diseases of the circulatory system in Taiwan: an analysis of mortality statistics.

Whether or not increased prevalence of oral contraceptive use in developing countries is associated with increased morbidity and mortality from circulatory system diseases is a serious concern for health and family planning administrators. An analysis of Taiwan's mortality statistics to determine whether such an association existed was undertaken, taking advantage of the excellent vital statistics and medical care systems existing there. The analysis failed to demonstrate that death rates from circulatory system diseases among Taiwanese women of childbearing age have increased since the promotion of oral contraceptive use began in 1967. In fact, mortality from all forms of circulatory system diseases has generally declined since 1967 and the slopes of declines for females of childbearing age who were exposed to oral contraceptives were somewhat greater than those of males of the corresponding age groups.

[Health status of children in an area of southern Brazil, 1980-1992: temporal trends and spatial distribution].

Although vital statistics are of paramount importance for health planning and program evaluation, few Brazilian states have vital registration systems with either sufficient coverage or agility to achieve these goals. The present analyses, based on data from the state of Rio Grande do Sul, describes time trends and the geographical distribution of infant and child health indicators, including infant mortality rates, proportionate infant mortality, low birthweight and vaccine coverage. From 1980 to 1992, marked reductions were observed for the infant mortality rate (from 39.0 to 19.3 per thousand) and in proportionate infant mortality (from 13.9% to 5.9% of all deaths). On the other hand, the prevalence of low birthweight remained stable between 8 and 10%, with a slight increase up to 1991. DPT vaccine coverage oscillated from year to year, ranging from 79 to 99%. There was close geographical correlation between the indices of low birthweight and infant mortality in the 17 health districts. The four indicators were combined into a single score for the purpose of identifying those health districts with the greater need for intervention. The southern districts, characterized by large land holdings presented the worst health indicators.

Cancer incidence at a hydrometallurgical nickel refinery.

Sherritt Gordon Mines Limited established hydrometallurgical nickel refining operations at Fort Saskatchewan, Alberta, in 1954. Records of workers with a minimum of one year's employment with Sherritt Gordon Mines were obtained and identification information as well as details of work history were collected and placed on computer. Cancer cases were identified by matching the study records with the computer listings of the Alberta Cancer Registry. Cancer deaths were verified utilizing record-linkage with death registrations of the Alberta Vital Statistics Division. The files of the Alberta Health Care Insurance Commission were used to ascertain the vital status of past employees of Sherritt Gordon Mines Limited. Among the 993 employees in the nickel refining and maintenance groups at Sherritt Gordon Mines, 30 cases of cancer were identified occurring at 13 diagnostic sites. No neoplasms of the nasal cavities or paranasal sinuses were found in the study population. Two cases of lung cancer were detected among maintenance workers. A single case of renal-cell cancer was diagnosed in the nickel-exposure category as well as in the maintenance group. None of the observed-to-expected cancer incidence ratios at the various diagnostic sites were statistically significant at the p less than 0.05 level.

Influence of a new province-wide trauma system on motor vehicle trauma care and mortality.

BACKGROUND: Mature trauma systems have evolved to respond to high rates of major injury morbidity and mortality. Characterized by prehospital care, triage, transportation, aggressive resuscitation, surgery, and rehabilitation, trauma systems have been found to improve survival for seriously injured patients. In Nova Scotia, a province-wide trauma system was implemented between 1995 and 1998. This study investigated the influence of the province-wide trauma system on motor vehicle trauma care and mortality in its first 2 years of existence. METHODS: Subjects over the age of 15 years were identified using E-codes pertaining to motor vehicle traffic crashes from population-based hospital claims and vital statistics data. Individuals who were hospitalized or died because of a motor vehicle crash in 1993 through 1994, before trauma system implementation, were compared with those who were hospitalized or died in 1999 through 2000, after the trauma system was implemented. RESULTS: In the 2-year period after trauma system implementation, there was a 21% increase in the number of seriously injured individuals with a primary admission to tertiary care. This increase was both clinically and statistically significant even after adjustment for age, gender, multiple injuries, head injury, municipality of residence, and vital status at discharge (RR, 1.21, 95% CI, 1.05-1.35). There was no evidence that the probability of dying while in hospital significantly changed in the first 2 years after trauma system implementation. INTERPRETATION: These results indicate that individuals seriously injured in motor vehicle crashes in Nova Scotia are more likely to be admitted to tertiary care in the postimplementation period.

The medical costs of gunshot injuries in the United States.

CONTEXT: The cost of treating gunshot injuries imposes a financial burden on society. Estimates of such costs are relevant to evaluation of gun violence reduction programs and may help guide reimbursement policies. OBJECTIVES: To develop reliable US estimates of the medical costs of treating gunshot injuries and to present national estimates for the sources of payment for treating these injuries. DESIGN AND SETTING: Cost analysis using E-coded discharge data from hospitals in Maryland for 1994-1995 and New York for 1994 and from emergency departments in South Carolina for 1997. Other sources of data included the National Electronic Injury Surveillance System for 1994 incidence of nonfatal gun injuries, the National Spinal Cord Injury Statistical Center database for 1988-1992 estimates of lifetime medical costs of gun injuries, and the 1994 Vital Statistics census for incidence of fatal gun injuries. MAIN OUTCOME MEASURES: Estimated national acute-care and follow-up treatment costs and payment sources for gunshot injuries. RESULTS: At a mean medical cost per injury of about $17000, the 134445 (95% confidence interval [CI], 109465-159425) gunshot injuries in the United States in 1994 produced $2.3 billion (95% CI, $2.1 billion-$2.5 billion) in lifetime medical costs (in 1994 dollars, using a 3% real discount rate), of which $1.1 billion (49%) was paid by US taxpayers. Gunshot injuries due to assaults accounted for 74% of total costs. CONCLUSIONS: Gunshot injury costs represent a substantial burden to the medical care system. Nearly half this cost is borne by US taxpayers.

Births and deaths: United States, 1996.

OBJECTIVES: This report presents preliminary data on births and deaths in the United States from the National Center for Health Statistics for 1996. U.S. data are shown by age, race, and Hispanic origin. National and State data on births by marital status, prenatal care, cesarean delivery, and low birthweight are also presented. Mortality data presented include life expectancy, leading causes of death, and infant mortality. METHODS: This report, the third in a new statistical series, presents preliminary data for 1996 on births and deaths based on a substantial sample of vital records. The records are weighted to independent control counts of births, infant deaths, and total deaths received in State vital statistics offices during calendar year 1996. RESULTS: According to preliminary data for 1996, the birth rate for teenagers dropped 4 percent in 1996 to 54.7 births per 1,000 women aged 15-19 years. The teen birth rate has declined 12 percent since 1991 (62.1), with larger reductions for young teenagers 15-17 years and for black teenagers. Birth rates for women aged 20-34 years increased 1-2 percent, while rates for women aged 35-44 years rose 3 percent. The number and percent of births to unmarried women increased about 1 percent, while the birth rate for unmarried women declined 1 percent. The rate of prenatal care utilization improved and the cesarean delivery rate declined. The overall low birthweight rate increased to 7.4 percent. The 1996 preliminary infant mortality rate reached a record low of 7.2 infant deaths per 1,000 live births with all-time lows for white and black infants. Life expectancy reached a record high of 76.1 years with all-time highs for white and black males and black females. The largest declines in age-adjusted death rates among the leading causes of death were for Human immunodeficiency virus (HIV) (26 percent) and Homicide (11 percent), which dropped from the 12th to the 14th leading cause of death.

Declining cancer mortality in the United States.

BACKGROUND: The overall age-adjusted cancer mortality rate had been increasing in the United States for as long as such statistics have been kept. This trend was reversed and a decline in cancer mortality began in 1991. METHODS: Vital statistics of the United States provided annual age-adjusted mortality rates for all forms of cancer and for lung carcinoma. Information from the Surveillance, Epidemiology, and End Results Program was also used to evaluate the effects on mortality of declining 5-year cancer case fatality. RESULTS: The overall age-adjusted cancer mortality rate declined in each succeeding year from 1990 to 1995 for a total reduction of about 3.1%. A major reduction occurred in lung carcinoma, which declined by 3.9%. Other smoking-related cancers declined by about 2%. The 5-year case fatality declined by approximately 0.5% per year from 1950-1954 to 1986-1991 for forms of cancer for which lead-time bias could be largely excluded. CONCLUSIONS: Both cancer prevention activities, especially those directed against smoking, and improvements in medical care have produced an appreciable reduction in cancer mortality in the United States. The nature of these changes suggests that the now ongoing decline will be sustained for the immediately foreseeable future.
