[Descriptive epidemiologic studies on geographical clusterings of pancreatic cancer mortality and incidence--an analysis in Niigata, Japan].

OBJECTIVES: The objectives of this study were to determine the mortality for pancreatic cancer in the 47 prefectures of Japan and to reveal the geographical distribution of the mortality and incidence for pancreatic cancer in Niigata. METHODS: Standardized mortality ratio (SMR) for pancreatic cancer in the 47 prefectures from 1998 to 2002 was calculated on the basis of the census and vital statistics of Japan. The same SMR in the 36 cities and counties in Niigata from 1995 to 2002 was calculated. These SMRs were compared with that of the national population. Then, standardized incidence ratio (SIR) for pancreatic cancer in the 36 cities and counties in Niigata from 1995 to 2002 was calculated on the basis of the Niigata Cancer Registry, compared with that of the general population of Niigata. RESULTS: The SMRs for pancreatic cancer for both sexes in Hokkaido, Aomori, Akita, Miyagi and Shimane were significantly higher than that of the national population (p<0.05). The SMR for males in Niigata was significantly high, whereas that for females was near the SMR of the national population. Among the 36 cities and counties in Niigata, significantly high SMRs for both sexes were observed only in Higashikanbara county; the SMRs [95% confidence interval (CI)] were 158.4 (104.4-230.5) and 172.2 (114.4-248.9) for males and females, respectively. CONCLUSIONS: Significantly high SMRs for pancreatic cancer were observed in Hokkaido and most of the Tohoku region. A geographical clustering of pancreatic cancer in Higashikanbara county was found. Further studies are needed to clarify the determinants of the clustering.

Predictors of referral to the North Carolina Child Service Coordination Program among infants with orofacial clefts.

OBJECTIVE: North Carolina has several programs that identify high-risk women and children for needed services, including the Child Service Coordination Program (CSCP). This study determines CSCP referral rates among infants with orofacial clefts (OFCs) and predictors of CSCP referral. We hypothesized receiving Medicaid and maternity care coordination (MCC) services increases the likelihood of CSCP referral. DESIGN AND SETTING: For births between 1999 and 2002, data were matched from North Carolina Vital Statistics, Health Services Information System (MCC and CSCP data), and North Carolina Birth Defects Monitoring Program. Multivariate analysis was used to determine crude and adjusted odds ratios for sociodemographic variables to predict CSCP referral. PARTICIPANTS: A total of 644 mothers of live-born infants with OFCs in North Carolina were identified. RESULTS: About 45% of infants with OFCs were referred to the CSCP. Infants of mothers who were at least 30 years of age and mothers who had more than a high school education were significantly less likely to be referred to the CSCP. Compared with infants with OFCs whose mothers did not receive Medicaid, mothers who received Medicaid were 1.9 times more likely to be referred to the CSCP, and mothers who received Medicaid and MCC services were 2.3 times more likely. CONCLUSIONS: Receipt of Medicaid and MCC services and receipt of Medicaid alone were positively associated with CSCP referral. Future studies should examine the effects of the duration of MCC services and factors related to the timeliness of CSCP referral.

Out-of-hospital cardiac deaths in adolescents and young adults in the United States, 1989 to 1998.

BACKGROUND: Out-of-hospital cardiac death (OHCD), often occurring suddenly and unexpectedly, is a major public health problem. The purpose of this study is to assess the epidemiologic pattern and secular trend of OHCD in adolescents and young adults aged 15-34 years in the United States. METHODS: United States national vital statistics mortality data from 1989 to 1998 were analyzed. OHCD was defined as death that occurred either at a pre-transport location, or in the emergency room, or was classified as "dead on arrival" in the emergency room, with an underlying cause of death as a cardiac disease (ICD-9 codes 390-398, 402, 404-429, 745, or 746). RESULTS: Of the 48,573 cardiac deaths occurring during 1989 to 1998, 31,827 (66%) were out of hospital. Of all OHCD victims from 1989 to 1998, 70% were men, and 76% were aged 25-34 years. The leading underlying causes of OHCD were coronary heart disease (29%), cardiomyopathy (18%), and arrhythmias (14%). The OHCD rates (per million population) were twice as high in men as in women (57.0 vs. 26.7 in 1997 and 1998), in African Americans as in whites (84.9 vs. 35.9 in 1997 and 1998), and increased with age. From 1989-1990 to 1997-1998, the age-adjusted OHCD death rates increased in both men (11%) and women (33%), and in African Americans (11%) and whites (19%). CONCLUSIONS: Although cardiac death remains rare in U.S. adolescents and young adults, the increased trend in OHCD rates in this age group warrants further investigation of etiology and prevention strategies.

Fire-related deaths among Aboriginal people in British Columbia, 1991-2001.

BACKGROUND: Fire-related mortality rates are known to be higher in Aboriginal people in BC. The purpose of this study was to describe the epidemiology and context of fire-related deaths in this population. METHODS: All death registrations attributable to fires in the province were identified by the B.C. Vital Statistics Agency (1991-2001). Age-specific death rates (ASDR) and age-standardized mortality rates (ASMR) were calculated for Status Indians and other residents. Data from Coroner's reports from the B.C. Coroners' Service (1997-2001) were used to describe the context of Aboriginal fire-related deaths. RESULTS: The overall fire-related ASMR for Status Indians and other residents were 0.66 deaths and 0.07 deaths/10,000 population respectively. Annual ASMR for both populations were constant over the study period. ASDR were higher in every age category for Status Indians; children and seniors had higher rates in both populations. Twenty-seven Aboriginal fatalities (20 fires) were identified for the contextual analysis. Key findings were: 48% of the total sample had elevated blood alcohol levels; 30% of the fires were caused by lit cigarettes (majority of decedents were intoxicated); 15% of the fires were caused by electric heating sources; at least 34% of fires occurred in homes with absent or non-functional smoke alarms. INTERPRETATION: Fire-related mortality among Aboriginal people in BC is a preventable public health concern. In this population, fire safety and prevention programs should consider improving the prevalence of functioning smoke alarms, promoting the safe use of heat sources, and decreasing smoking behaviours and the use of alcohol.

Discrepancies in birth weights between hospital records and health department data for low birth weight infants in New York City.

The study is one of the first to compare corresponding birth weights documented on New York City Health Department Vital Statistics (HDVS) birth tapes and the neonatal medical records of the hospital of birth. Only those infants with birth weights of 2,500 grams (g) or less were studied. Analyses were made of the scope, magnitude of error, and direction of the discrepancies observed. Concordance was considered present if the discrepancy in birth weight was 30 g or less. HDVS birth tapes and the hospital charts of 3,864 neonates were reviewed. The study population came from 48 of 53 hospitals in the metropolitan area. Hospitals were divided into three categories by the level of care offered. Each level of care was subdivided into groups by type of hospital ownership, that is, proprietary, voluntary, and municipal. Concordance was 87 percent overall and ranged from 67 to 96 percent among the study hospitals. More discrepancies were found for levels II and III hospitals than in level I hospitals, those with less sophisticated resources. Municipal hospitals had more discrepancies in birth weights than voluntary hospitals. Infants who had been transported from the birth facility to another facility had significantly higher concordance rates than the nontransported infants, after adjusting for levels of care, type of ownership of the hospital, and birth weight categories. Increased concordance rates were shown to be associated with increased birth weights.

Deaths: preliminary data for 2000.

OBJECTIVES: This report presents preliminary data on deaths for the year 2000 in the United States. U.S. data on deaths are shown by age, sex, race, and Hispanic origin. Data on life expectancy, leading causes of death, and infant mortality are also presented. METHODS: Data in this report are based on a large number of deaths comprising more than 94 percent of the demographic file and 85 percent of the medical file for all deaths in the United States in 2000. The records are weighted to independent control counts of infant deaths, and deaths 1 year and over received in State vital statistics offices for 2000. Unless otherwise indicated, comparisons are made with final data for 1999. For certain causes of death, preliminary data differ from final data because of the truncated nature of the preliminary file. These are, in particular, accidents, homicides, suicides, and respiratory diseases. RESULTS: The age-adjusted death rate in 2000 for the United States decreased slightly from 1999 to a record low in 2000. For causes of death, declines in age-adjusted rates occurred for heart disease, stroke, Chronic liver disease and cirrhosis, diabetes, and cancer. Age-adjusted rates for drug-induced deaths, alcohol-induced deaths, and firearm injuries also decreased during 2000. Declines also occurred for homicides, suicides, unintentional injuries, and Chronic lower respiratory diseases although the extent of the declines cannot be precisely assessed based on the preliminary data. Age-adjusted death rates increased between 1999 and 2000 for the following causes: Pneumonitis from solids and liquids, Alzheimer's disease, kidney disease, hypertension, Influenza and pneumonia, and Septicemia. The infant mortality rate for the black population was 4 percent lower, while the rate for the white population decreased (nonsignificantly) by 2 percent. Life expectancy at birth rose by 0.2 years to a record high of 76.9 years.

Epidemiology of constipation in the United States.

In the present study, the epidemiology of constipation in the United States and an assessment of its impact on national health are presented. This analysis was based on four different surveys, i.e., the National Health Interview Survey, the National Hospital Discharge Survey, the National Ambulatory Medical Care Survey, and the Vital Statistics of the United States. These surveys have estimated that over 4 million people in the United States have frequent constipation, corresponding to a prevalence of about 2 percent. Constipation was the most common digestive complaint in the United States, outnumbering all other chronic digestive conditions. Cathartics and laxatives were prescribed to 2 to 3 million patients yearly by general and family practitioners or internists. In 92,000 annual hospitalizations, constipation was listed among the discharge diagnoses. About 900 persons die annually from diseases associated with or related to constipation. Constipation was three times more common in women than men. It showed a marked increase after the age of 65 years. It appeared to affect nonwhites 1.3 times more frequently than whites. In addition, constipation was more frequent in people living in the South than elsewhere in the United States, and in people from families with low income or brief education of the head of family than in people from families with high income or a high educational level of their family head. These data suggest that there are other factors involved in the cause of constipation in addition to dietary fiber content and psychogenic influences. The frequent occurrence of constipation and its impact on public health stress the need for further studies devoted to the epidemiology and basic pathophysiology of this condition.

Constant multiple birth rates in the Czech Republic and the Slovak Republic until recently, 1972-1995.

Using vital statistics, yearly changes in the twinning and triplet rates by zygosity were investigated in the Czech Republic and the Slovak Republic during the period 1972-1995. Monozygotic (MZ) twinning rates in both countries had remained nearly constant (about 3 per 1000 total births) during that period. With a few exceptions, the dizygotic (DZ) twinning rates remained constant from 1972 to 1994, and increased in 1995 for both countries. MZ twinning rates for both countries were the lowest in Europe. As for triplet rates, overall rates increased significantly year by year in the Czech Republic, but not in the Slovak Republic. The triplet rate was significantly higher in 1995 than in the period 1972-1982 for both countries. The MZ triplet rate remained constant during that period in the Czech Republic. The trizygotic (TZ) triplet rates increased 3-fold for the Czech Republic and 4-fold for the Slovak Republic in 1972-1976 and 1992-1995. In the later period, the TZ rate was 1.5-fold higher in the Czech Republic than in the Slovak Republic. The quadruplet rate increased 2.3-fold from 2.9 per million births in 1982-1986 to 6.7 in 1992-1995 in the Czech Republic. The corresponding values were 2.7, 2.20 and 5.9-fold in the Slovak Republic. Both the Czech and the Slovak Republics were not affected by fertility drugs and assisted reproductive techniques until recently.

Perinatal mortality in triplet births in Japan: time trends and factors influencing mortality.

Perinatal mortality rates (PMRs) in triplets were analyzed using Japanese Vital Statistics during the period of 1980-1998. The total number of perinatal deaths in triplets was 1051. The PMR significantly decreased from 214 per 1000 births in 1980 to 39 in 1998, a reduction of 82%. PMRs in triplets were 11.1-fold higher in 1980 and 6.9-fold higher in 1998 than in singletons, indicating that PMRs improved more in triplets than in singletons during the last two decades in Japan. The PMR was the highest in the third-born, followed by the second- and the first-born triplets in each period. As for maternal age, the PMR was 1.5-3.7 times higher in the < 25 years of age group than the other age groups. Additionally, the PMR was the lowest for birthweight (BW) >or= 2000 g during the entire period. In addition, the PMR decreased with gestational age (GA) of up to 38-39 weeks and increased thereafter. The effects of BW on the PMR were stronger than the effects of GA. The proportion of perinatal deaths in triplets with extremely low BW (< 1000 g) was 74% in 1980-1989 and increased to 82% in 1990-1998. The declining PMR was unlikely to be due to the improvement in BW in triplets. It is likely that it was related to the improved medical management of triplets during the perinatal period and the first week of life. Information obtained in the present study may be useful in counseling pregnant woman about triplet births.

A comparison of the alcohol-attributable mortality in four European countries.

BACKGROUND: Deaths due to alcohol consumption are an important component of all-cause mortality, particularly premature mortality. However, there are considerable regional variations, the reasons for which are unclear. METHODS: Estimates were made as reliably as possibly using vital statistics and best estimates of risk of the alcohol-attributable mortality, by age, sex and cause for four European countries (England and Wales, Germany, Denmark and Italy). Twenty-seven alcohol-related conditions were considered including the possible cardio-protective effects of alcohol. RESULTS: It was estimated that there are approximately 2% fewer deaths annually in England and Wales than would be expected in a non-drinking population and 0.3% fewer deaths among East German females. In West Germany, Denmark, Italy and among East German males there are more deaths caused by alcohol than are prevented (between 0.7 and 2.6% of all deaths). The highest age-specific proportion of alcohol-attributable deaths is found in East Germany where around 30% of deaths among males aged 25-44 years are due to drinking. Among young men in all four countries the largest contributor to alcohol-related deaths is road traffic accidents involving alcohol. CONCLUSIONS: Possible explanations for the variation in alcohol-attributable deaths between countries include different underlying heart disease rates, different patterns of alcohol consumption and beverage preferences, and different use of mortality classification. Differences in the reported alcohol consumption levels explain little of the variation in alcohol-attributable deaths. Estimating alcohol-attributable mortality by age and sex across countries may be a useful indicator for developing alcohol strategies and exploring ways of preventing premature mortality.

Sudden cardiac death in the United States, 1989 to 1998.

BACKGROUND: Sudden cardiac death (SCD) is a major clinical and public health problem. METHODS AND RESULTS: United States (US) vital statistics mortality data from 1989 to 1998 were analyzed. SCD is defined as deaths occurring out of the hospital or in the emergency room or as "dead on arrival" with an underlying cause of death reported as a cardiac disease (ICD-9 code 390 to 398, 402, or 404 to 429). Death rates were calculated for residents of the US aged >/=35 years and standardized to the 2000 US population. Of 719 456 cardiac deaths among adults aged >/=35 years in 1998, 456 076 (63%) were defined as SCD. Among decedents aged 35 to 44 years, 74% of cardiac deaths were SCD. Of all SCDs in 1998, coronary heart disease (ICD-9 codes 410 to 414) was the underlying cause on 62% of death certificates. Death rates for SCD increased with age and were higher in men than women, although there was no difference at age >/=85 years. The black population had higher death rates for SCD than white, American Indian/Alaska Native, or Asian/Pacific Islander populations. The Hispanic population had lower death rates for SCD than the non-Hispanic population. From 1989 to 1998, SCD, as the proportion of all cardiac deaths, increased 12.4% (56.3% to 63.9%), and age-adjusted SCD rates declined 11.7% in men and 5.8% in women. During the same time, age-specific death rates for SCD increased 21% among women aged 35 to 44 years. CONCLUSIONS: SCD remains an important public health problem in the US. The increase in death rates for SCD among younger women warrants additional investigation.

A comparative study of zygotic twinning and triplet rates in eight countries, 1972-1999.

Annual changes in twinning and triplet rates by zygosity were investigated in eight countries during the period 1972-1999 using vital statistics. The monozygotic (MZ) twinning rates in Denmark, Switzerland and the Slovak Republic remained more or less constant throughout this period, whereas those in England and Wales, the Federal Republic of Germany (Germany), the Netherlands, the Czech Republic and Japan increased significantly year by year. With the exception of the Slovak Republic, the dizygotic (DZ) twinning rate increased significantly year by year in each country. It was 2.9 times higher in Denmark and 1.5 times higher in Germany in 1999 than in 1972, and within the same range in the other countries. With two exceptions, the MZ triplet rates remained more or less constant in each country. On the other hand, the DZ and trizygotic (TZ) triplet rates increased significantly year by year in each country. The TZ rate increased 30-fold in Germany, 16.6-fold in Japan, 11.7-fold in Switzerland, 9.7-fold in the Czech Republic, 8.7-fold in the Netherlands, 6.4-fold in Denmark, 5.6-fold in England and Wales and 3.5-fold in the Slovak Republic. The higher DZ twinning rate and higher DZ and TZ triplet rates since 1983 have been attributed to the higher proportion of mothers being treated with ovulation-inducing hormones and in vitro fertilization (IVF) in Denmark, England and Wales, Germany, the Netherlands, Switzerland and Japan. After the introduction of fertility drugs and IVF, variations in the DZ twinning and triplet rates and the TZ triplet rates were not only due to biological factors, but also depended on the popularity of fertility drugs and IVF in each country. In the Slovak Republic, where human fertility might not be affected by some adverse environmental factors, the DZ:MZ ratio remained constant during the period 1972-1999.

US asthma mortality: 1941 to 1989.

BACKGROUND: Asthma mortality in the United States has nearly doubled in the past 10 years. An examination of long-term trends in United States asthma mortality places the current mortality rates in a historical perspective, identifies high-risk groups for interventions, and may provide clues to the etiology of asthma mortality. METHODS: Asthma deaths for the population aged 5 to 34 years were abstracted from United States vital statistics reports for the period 1941 through 1989. Race-specific and sex-specific mortality rates were age-adjusted to the 1989 estimate of the US population. RESULTS: Among the population aged 5 to 34 years, three distinct periods of asthma mortality were observed: 1941 to 1964, 1965 to 1977, and 1978 to 1989. From 1941 through 1964, nonwhites exhibited a gradual increase in asthma mortality rates; in contrast, whites showed no change in mortality rates. From 1965 through 1977, a marked decline in mortality rates was observed among both nonwhites and whites. From 1978 through 1989, asthma mortality increased with a near doubling in the mortality rates in both nonwhites and whites. Overall, nonwhites had mortality rates 4 times those of whites, with nonwhite males aged 15 to 34 at the greatest risk of death due to asthma. Age and sex differences in asthma mortality are also apparent. The population aged 15 to 34 years generally had mortality rates greater than the population aged less than 15 years. For the population aged 5 to 14 years, regardless of calendar year, females had lower mortality rates than males. Among the population aged 15 to 34 years, females experienced twice the mortality rates of males prior to 1965; however, by the 1980s this relationship no longer existed. CONCLUSIONS: The asthma mortality rate for nonwhites was 4-fold higher than for whites, although the reported prevalence of asthma is less than 2-fold greater. The population aged 15 to 34 years had higher mortality rates than the population aged 5 to 14 years despite exhibiting a lower prevalence of asthma. There are also gender differences in asthma mortality. These differences may be attributable to differences in asthma severity, or differences in disease management or reflect actual differences in mortality. These findings suggest that the search for clues to understand the increase in asthma mortality from 1978 to 1989 should include an attempt to understand why asthma mortality declined in the preceding decade from 1967 to 1977 as these may not be completely unrelated trends.

A comprehensive evaluation of family history and breast cancer risk. The Utah Population Database.

OBJECTIVE: The purpose of this study is to assess the impact of family history on the risk of developing breast cancer. DESIGN: A case-control study design was used. SETTING: To provide a comprehensive assessment of family history risk, we used the Utah Population Database, a linked database compiled of genealogy data of the descendants of Mormon pioneer families, cancer data from the Utah Cancer Registry, and mortality data from the Utah Department of Vital Statistics. PATIENTS: All women diagnosed with breast cancer who were in the genealogy database and the Utah Cancer Registry were included. Controls were women selected from the genealogy, who like cases had no record of previous cancer. They were matched to the cases by age and place of birth. OUTCOME: Several definitions of family history were used. The total familial risk variable, developed to work effectively in the Utah Genealogy Database, accounts for all family members, their degree of relatedness to the case, and the amount of time they were observed for possible cancer diagnosis. RESULTS: A threefold increase in risk, estimated by the odds ratio (OR), of breast cancer among those with the highest family history score (6% of cases) was observed when compared with those with the lowest family history score. The OR for women with a first-degree relative with breast cancer was 2.45 (95% confidence interval [CI], 1.84 to 3.06). If the nearest relative was a second-degree relative, the OR was 1.82 (95% CI, 1.39 to 2.24); if the nearest relative was a third-degree relative, the OR was 1.35 (95% CI, 1.07 to 1.64). A slightly greater risk was observed if the first-degree relative was a woman's mother (OR, 2.44; 95% CI, 1.77 to 3.42) rather than a sister (OR, 2.01; 95% CI, 1.66 to 2.43). Among subjects diagnosed before the age of 50 years, the disease experience of relatives prior to age 50 was most important, while for older subjects the experience of relatives of all ages was of roughly equal importance. Women who developed contralateral breast cancer within 3 years of initial diagnosis were nearly 10 times as likely as women without breast cancer to have a first-degree relative with breast cancer. Based on the risk estimates in this study, we have estimated that approximately 17% to 19% of breast cancer in the population could be attributed to family history. Women who had a first-degree relative with colon cancer had a 30% increased risk of breast cancer. CONCLUSIONS: In this study population, women with a family history of breast cancer, even if the nearest relative with breast cancer is a third-degree relative, are at increased risk of the disease.

[Secular changes of the mean birth weight in Japan during the past 20 years (single births, 1969-88)].

Using vital statistics (1981-1988) of the Japanese government, the mean birth weight (MBW) classified by sex was calculated from a birth weight distribution of the single births with 500g intervals for all Japan, prefectures and regions. These MBWs were linked with the MBW of 1969-1980 in our previous reports (Ref. 1) 2)). The MBWs of single births for twenty years (1969-1988) were investigated and it was pointed out that the MBWs classified by area (all Japan, prefectures and regions) were on the decrease recently and that the areal differences of the MBW were becoming large. For all Japan a secular change in the MBW was discussed for the term of a standard deviation, a skewness, a kurtosis, and relative frequencies of less than 2500g (weight class 1), those from 2500g to 3999g (weight class 2) and those of 4000g or more (weight class 3). These investigations revealed that birth weights of Japan have had a tendency to have a small standard deviation, a negative skewness, and a large kurtosis. Weight class 1 decreased until 1976 and increased after this year. Weight class 2 was on the increase up to 1988, and weight class 3 increased until 1973 and decreased afterward, as if it were accompanied by the MBW. For the purpose of confirming the contribution of each weight class to the annual change of the MBW, an analytical method for the weight frequency distribution was proposed as follows. Let M, M', pi and pi' represent the MBW of a given year (year A), the MBW of an another year (year B), the relative frequency of the i-th weight class in year A and that in year B, respectively. Suppose that M(i)'' represents the MBW when only the i-th weight class has pi as a relative frequency even in year B. Then, as the result of a fairly simple calculation, the difference between the MBW in year A and that in year B, M'-M, is obtained as follows; M'-M = sigma (1-pi') (M'-M(i)''). Therefore, the amount (1-pi') (M'-M(i)'') is able to be considered as a share of the i-th weight class in relation to the difference of M'-M. Accordingly, the share proportioned to the summation of the absolute amount [formula: see text] may represent the degree of the contribution of the i-th weight class to the difference, M'-M.(ABSTRACT TRUNCATED AT 400 WORDS)

Health status of urban American Indians and Alaska Natives. A population-based study.

OBJECTIVE: To use vital statistics and communicable disease reports to characterize the health status of an urban American Indian and Alaska Native (AI/AN) population and compare it with urban whites and African Americans and with AI/ANs living on or near rural reservations. DESIGN: Descriptive analysis of routinely reported data. SETTING: One metropolitan county and seven rural counties with reservation land in Washington State. SUBJECTS: All reported births, deaths, and cases of selected communicable diseases occurring in the eight counties from 1981 through 1990. MAIN OUTCOME MEASURES: Low birth weight, infant mortality, and prevalence of risk factors for poor birth outcomes; age-specific and cause-specific mortality; rates of reported hepatitis A and hepatitis B, tuberculosis, and sexually transmitted diseases. RESULTS: Urban AI/ANs had a much higher rate of low birth weight compared with urban whites and rural AI/ANs and had a higher rate of infant mortality than urban whites. During the 10 years, urban AI/AN infant mortality rates increased from 9.6 per 1000 live births to 18.6 per 1000 live births compared with no trend among the other populations. Compared with rural AI/AN mothers, urban AI/AN mothers were 50% more likely to receive late or no prenatal care during pregnancy. Relative to urban whites, urban AI/AN risk factors for poor birth outcomes (delayed prenatal care, adolescent age, and use of tobacco and alcohol) were more common and closely resembled the prevalence among the African-American population except for a higher rate of alcohol use among AI/ANs. Compared with urban whites, urban AI/AN mortality rates were higher in every age group except the elderly. Differences between urban whites and AI/ANs were largest for injury- and alcohol-related deaths. All-cause mortality was lower among urban AI/ANs compared with rural AI/ANs and urban African Americans, although injury- and alcohol-related deaths were higher for AI/ANs. All communicable diseases studied were significantly (P < .05) more common among urban AI/ANs compared with whites. Tuberculosis rates were highest in the urban AI/AN group, but rates of sexually transmitted diseases were intermediate between urban whites and African Americans. CONCLUSIONS: In this urban area, great disparities exist between the health of AI/ANs and whites across almost every health dimension we measured. No consistent pattern was found in the comparison of health indicators between urban and rural AI/ANs, though rural AI/ANs had lower rates of low birth weight and higher rates of timely prenatal care use. The poor health status of urban AI/AN people requires greater attention from federal, state, and local health authorities.
