The Body Mass Index-Mortality Relationship in White and African American Women

Objective : To examine the association of body mass index to all-cause and cardiovascular disease (CVD) mortality in white and African American women. Research methods and procedures : Women who were members of the American Cancer Society Prevention Study I were examined in 1959 to 1960 and then followed 12 years for vital status. Data for this analysis were from 8,142 black and 100,000 white women. Body mass index (BMI) was calculated from reported height and weight. Associations were examined using Cox proportional hazards modeling with some analyses stratified by smoking (current or never) and educational status (less than complete high school or high school graduate). Results : There was a significant interaction between ethnicity and BMI for both all-cause (p<0.05) and CVD mortality (p<<0.001). BMI (as a continuous variable) was associated with all-dause mortality in white women in all four groups defined by smoking and education. In black women with less than a high school education, there were no significant associations between BMI mortality. For high school-educated black women, there was a significant association between BMI and all-cause mortality. Among never smoking women with at least a high school education, models using the lowest BMI as the reference indicated a 40% higher risk of all-cause mortality at a BMI of 35.9 in black women vs. 27.3 in white women. Discussion : The impact of BMI on mortality was modified by educational level in black women; however, BMI was a less potent risk factor in black women than in white women in the same category of educational status.     

Widening of socioeconomic inequalities in U.S. death rates, 1993-2001

Background

Socioeconomic inequalities in death rates from all causes combined widened from 1960 until 1990 in the U.S., largely because cardiovascular death rates decreased more slowly in lower than in higher socioeconomic groups. However, no studies have examined trends in inequalities using recent US national data.

Methodology/Principal Findings

We calculated annual age-standardized death rates from 1993–2001 for 25–64 year old non-Hispanic whites and blacks by level of education for all causes and for the seven most common causes of death using death certificate information from 43 states and Washington, D.C. Regression analysis was used to estimate annual percent change. The inequalities in all cause death rates between Americans with less than high school education and college graduates increased rapidly from 1993 to 2001 due to both significant decreases in mortality from all causes, heart disease, cancer, stroke, and other conditions in the most educated and lack of change or increases among the least educated. For white women, the all cause death rate increased significantly by 3.2 percent per year in the least educated and by 0.7 percent per year in high school graduates. The rate ratio (RR) comparing the least versus most educated increased from 2.9 (95% CI, 2.8–3.1) in 1993 to 4.4 (4.1–4.6) in 2001 among white men, from 2.1 (1.8–2.5) to 3.4 (2.9–3–9) in black men, and from 2.6 (2.4–2.7) to 3.8 (3.6–4.0) in white women.

Conclusion

Socioeconomic inequalities in mortality are increasing rapidly due to continued progress by educated white and black men and white women, and stable or worsening trends among the least educated.     

Those ubiquitous fertility trends: United States, 1945-1979

1970-79 US fertility trends among differnet racial, regional, age, educational, parity, and socioeconomic subgroups in the population were examined, using own children data from the 1976 Survey of Income and Education (SIE) and the March Current Population Surveys (CPS) from 1968-80. In addition, cross-sectional differences in fertility for the subgroups were compared for 1970 and 1976, using multiple regression analysis. 1st, the appropriateness of using fertility rates obtained from own children data was assessed by comparing fertility rates obtained from the SIE data with those derived from vital statistic and census data. The comparative analysis confirmed that the SIE data yielded an accurate estimate of period fertility rates for currently married women, provided the subgroup samples were sufficiently large. CPS fertility estimates were also judged to be accurate if data from 3 adjacent survey years was pooled to increase sample size. Fertility trends for 5 educational groups were assessed separately for 1967-73. During this periold, there was a marked decline in fertility for all 5 groups; for the group with 5-8 years of education the decline was only 14%, but for the other 4 groups, which included women with 9-16 or more years of education, the decline in fertility ranged from 26-29%. In assessing the 1970-76 trends, the sample was restricted to own children, aged 3 years or less, of currently married women, under 40 years of age. Among whites, there was an overall 20% decline in fertility between 1970-76 and an overall fertility increase of about 2% between 1976-79. These trends were observed in all 28 white subgroups. A similar pattern was observed for blacks. There was an overall fertility decline of 24% between 1970-76, and this decline was apparent for all subgroups except women with college degrees. Betwen 1976-79, black fertility rates, unlike white rates, continued to decline, but the rate of decline was only 3%. Furthermore, the decline in almost all the black subgroups was markedly less than in the 1970-76 periold, and for many of the subgroups the trend was reversed and fertility increased. In summary, the fertility trends noted for 1970-79 were pervasive for almost all the subgroups for both blacks and whites; i.e., there was a marked decline in fertility between 1970-76 and than a reversal or slowing down of the decline during the 1976-79 for all black and white subgroups. Cross-sectional fertility differences in the subgroups in 1970 and in 1979 were quite similar, and fertility rates differed markedly for the separate subgroups. These differences do not, of course, explain the pervasive trends observed in the analysis of the fertility rates over time. A similar study assessing fertility trends among subgroups for the early 1940's through the late 1960s also revealed the pervasive nature of period fertility trends. Demographers have not as yet been able to explain these shifts in fertility that cut across all subgroups in the US and which also characterize the period fertility rates in other developed countries. Tables provided information on 1) total fertility rates by educational level and by geographical region for 1945-1975; 2) % change in number of own children less than 3 years of age among women under age 40 by maternal age, maternal education, initial parity, geographical region, and husband's income; and 3) mean number of own children less than 3 years of age among women under age 40 by maternal age, education, parity, region, and husband's income.     

Adverse Trends in Ischemic Heart Disease Mortality among Young New Yorkers,Particularly Young Black Women

Background

Ischemic heart disease (IHD) mortality has been on the decline in the United States for decades. However, declines in IHD mortality have been slower in certain groups, including young women and black individuals.

Hypothesis

Trends in IHD vary by age, sex, and race in New York City (NYC). Young female minorities are a vulnerable group that may warrant renewed efforts to reduce IHD.

Methods

IHD mortality trends were assessed in NYC 1980–2008. NYC Vital Statistics data were obtained for analysis. Age-specific IHD mortality rates and confidence bounds were estimated. Trends in IHD mortality were compared by age and race/ethnicity using linear regression of log-transformed mortality rates. Rates and trends in IHD mortality rates were compared between subgroups defined by age, sex and race/ethnicity.

Results

The decline in IHD mortality rates slowed in 1999 among individuals aged 35–54 years but not ≥55. IHD mortality rates were higher among young men than women age 35–54, but annual declines in IHD mortality were slower for women. Black women age 35–54 had higher IHD mortality rates and slower declines in IHD mortality than women of other race/ethnicity groups. IHD mortality trends were similar in black and white men age 35–54.

Conclusions

The decline in IHD mortality rates has slowed in recent years among younger, but not older, individuals in NYC. There was an association between sex and race/ethnicity on IHD mortality rates and trends. Young black women may benefit from targeted medical and public health interventions to reduce IHD mortality.     

Comparison of black and white patients attending hypertension clinics in England.

Reports suggest that hypertension and death due to hypertensive disease are commoner among black than among white people. One hundred and thirty-five black patients attending hypertension clinics at three English hospitals were compared with age-, sex-, and clinicmatched white patients. The black women had higher blood pressures and weighed more than the white women, but there were no differences between the men. The black patients had not increased risk from family, obstetric, or smoking history. Proteinuria and nocturia were more common in black patients while urinary infections were less common. Heart size and left ventricular voltage were greater in black patients. Haemoglobin and plasma cholesterol and triglyceride concentrations were smaller and serum globulin concentration greater in black patients. No difference in response to treatment, attributable to race, was observed during the period of clinic attendance, which averaged 1.7 years. There was a slightly greater rate of default among black men during the first year of attendance.     

Education,Health Behaviors,and the Black-White Difference in Waist-to-Hip Ratio

Few epidemiologic studies have investigated the impact of body mass index, low educational attainment, cigarette smoking, and physical activity on the considerable black-white difference in waist-to-hip ratio. These relationships were assessed with multi-variable linear regression among 3,094 adults (24% black) who were examined in 1987 in South Carolina. The unadjusted mean waist-to-hip ratio was lower for black men than for white men (-0.03 units) and higher for black women than for white women (+0.03 units). After adjustment for age, body mass index, education, smoking, and physical activity, the black-white difference in mean waist-to-hip ratio was ?0.02 units (p<0.001) among men and +0.01 units (p<0.01) among women. Although differing distributions of age, body mass index, and educational attainment accounted for a 59% reduction in the black-white difference among women, these factors did not explain the difference among men. Thus, these results suggest that other environmental or biologic factors may also play an important role in the marked variation in body fat distribution between the two ethnic groups. The results also support the importance of the prevention of cigarette smoking and overweight in potentially preventing abdominal obesity in both black adults and white adults.     

The effect of race on the incidence of low birth weight: persistence of effect after controlling for socioeconomic, educational, marital, and risk status

The purpose of this study was to determine whether the elevated risk for low birth weight (LBW) infants among black mothers would persist when biologic, behavioral, and socioeconomic factors (as measured by socioeconomic status, level of education, and marital status) were controlled. It was found that the odds ratios for the risk of LBW for blacks/whites persisted above 1.5, regardless of what subgroups were used and what factors were controlled. The black/white odds ratios were, however, less than 2.0 when cigarette smoking was not a risk factor and higher than 2.0 when it was. In fact, the highest odds ratios, up to 2.65, occurred among the smoking group. These data suggest that smoking may have a more strongly negative effect among black than white pregnant mothers. In general, the effect of race on the LBW risk was much less strong than that of risk factors that can be influenced, such as adverse maternal practices.     

Educational differences in obesity in the United States: a closer look at the trends

Both body weight and educational attainment have risen in the United States. Empirical evidence regarding educational differences in obesity (BMI ≥30) is inconsistent. According to some widely cited claims, these differences have declined since the 1970s, and the most educated have experienced the greatest gain in obesity. Prior research was limited in grouping college graduates with nongraduates, combining men and women in the same analysis, and using self-reported rather than measured anthropometric information. Using the National Health and Nutrition Examination Surveys (NHANES), we address these issues and examine changing educational differences in obesity from 1971-1980 to 1999-2006 for non-Hispanic whites and blacks in two separate age groups (25-44 vs. 45-64 years). We find that (i) obesity differentials by education have remained largely stable, (ii) compared with college graduates, less educated whites and younger black women continue to be more likely to be obese, (iii) but the differentials are larger for women than men, and weak or nonexistent among black men and older black women. There are exceptions to the overall trend. The obesity gap has widened between the two groups of college-educated younger women, but disappeared between the least and most educated younger white men. Thus, the increase in obesity was similar for most educational groups, but significantly greater for younger women with some college and smaller for younger white men without a high-school degree. Lumping together the two distinct college groups has biased previous estimates of educational differences in obesity.     

Educational status,coronary heart disease,and coronary risk factor prevalence in a rural population of India.

OBJECTIVE--To define the association between educational level and prevalence of coronary heart disease and coronary risk factors in India. DESIGN--Total community cross sectional survey with a doctor administered questionnaire, physical examination, and electrocardiography. SETTING--A cluster of three villages in rural Rajasthan, western India. SUBJECTS--3148 residents aged over 20 (1982 men, 1166 women) divided into various groups according to years of formal schooling. RESULTS--Illiteracy and low educational levels were associated with less prestigious occupations (agricultural and farm labouring) and inferior housing. There was an inverse correlation of educational level with age (rank correlation: mean -0.45, women -0.49). The prevalence of coronary heart disease (diagnosed by electrocardiography) was significantly higher among uneducated and less educated people and showed an inverse relation with education in both sexes. Among uneducated and less educated people there was a higher prevalence of the coronary risk factors smoking and hypertension. Educational level showed a significant inverse correlation with systolic and diastolic blood pressure. Logistic regression analysis with adjustment for age showed that educational level had an inverse relation with prevalence of electrocardiographically diagnosed coronary heart disease (odds ratio: men 0.82, women 0.53), hypertension (men 0.88, women 0.56), and smoking (men 0.73, women 0.65) but not with hypercholesterolaemia and obesity. The inverse relation of coronary heart disease with educational level abated after adjustment for smoking, physical activity, body mass index, and blood pressure (odds ratio: men 0.98, women 0.78). CONCLUSION--Uneducated and less educated people in rural India have a higher prevalence of coronary heart disease and of the coronary risk factors smoking and hypertension.     

Social-economic inequality in mortality among older mem amd women. Research on the role of health, life style, parental socio-economic status and psychosocial conditions

This article describes to what degree socio-economic differences exist among community living older men and women, and to what degree these differences are to be explained by health, behaviour, childhood and psychosocial conditions. The data are available from 1427 men and 1503 women (aged 55-85), participating in the Longitudinal Aging Study Amsterdam (LASA) in 1992/1993. As indicators of socio-economic status (ses) we used the highest level of education and net monthly income. Age-adjusted mortality risks for men and women with low income and for men with a low level of education are about 1.5 times as high as for to the persons with high income and educational level. Among men, but not among women, the difference in mortality risk between low and high status persons remains after adjustment for age, health status, and several risk factors. Differences in lifestyle, parental ses and psychosocial characteristics explain little to nothing of the age-adjusted ses-differentiation in mortality. It is concluded that ses-inequalities in mortality are present among Dutch men and, to a lesser extent among women, until high age, and are partly explained by the relatively large health problems of the lower status group.     

Racial/Ethnic Disparities in Obesity Among US‐born and Foreign‐born Adults by Sex and Education

This study examines sex and education variations in obesity among US‐ and foreign‐born whites, blacks, and Hispanics utilizing 1997–2005 data from the National Health Interview Survey on 267,585 adults aged ≥18 years. After adjusting for various demographic, health, and socioeconomic factors via logistic regression, foreign‐born black men had the lowest odds for obesity relative to US‐born white men. The largest racial/ethnic disparity in obesity was between US‐born black and white women. High educational attainment diminished the US‐born black–white and Hispanic–white disparities among women, increased these disparities among men, and had minimal effect on foreign‐born Hispanic–white disparities among women and men. Comprehension of these relationships is vital for conducting effective obesity research and interventions within an increasingly diverse United States.     

Educational inequalities in cancer incidence and mortality in Lithuania: A record linkage study

BackgroundThe aim of this study is to describe associations between incidence and mortality by major cancer sites and education in Lithuania.MethodsThe study is based on the linkage between all records of the 2001 population census and all records from Lithuanian Cancer Registry (cancer incidence) and Statistics Lithuania (deaths) for the period between 1 July 2001 and 31 December 2004. Education-specific incidence and mortality rate ratios were estimated by means of multivariate Poisson regression models.ResultsWe found both the positive and inverse educational gradients in cancer incidence and mortality. The risk of developing cancer (all sites) was lower among men and women with the lowest education, whereas cancer mortality was higher among lower educated men. The higher educational level was also associated with an increased risk of prostate cancer among men and an increased risk of breast cancer among women. However, prostate cancer mortality was the highest in the lowest education group, whereas breast cancer mortality among women did not show any statistically significant differences. Lower educated men had significantly higher incidence and mortality due to lung and stomach cancers. Strikingly high incidence and mortality due to cervix cancer was observed among women with secondary and lower than secondary education.ConclusionThe results point to inequalities in early diagnosis and survival from cancer and failures ensuring equal access to medical care. Further more in-depth studies are needed in order to understand the nature and determinants of these inequalities.     

Four Decades of Educational Inequalities in Hospitalization and Mortality among Older Swedes

Background

The inverse association between education and mortality has grown stronger the last decades in many countries. During the same period, gains in life expectancy have been concentrated to older ages; still, old-age mortality is seldom the focus of attention when analyzing trends in the education-mortality gradient. It is further unknown if increased educational inequalities in mortality are preceded by increased inequalities in morbidity of which hospitalization may be a proxy.

Methods

Using administrative population registers from 1971 and onwards, education-specific annual changes in the risk of death and hospital admission were estimated with complimentary log-log models. These risk changes were supplemented by estimations of the ages at which 25, 50, and 75% of the population had been hospitalized or died (after age 60).

Results

The mortality decline among older people increasingly benefitted the well-educated over the less well-educated. This inequality increase was larger for the younger old, and among men. Educational inequalities in the age of a first hospital admission generally followed the development of growing gaps, but at a slower pace than mortality and inequalities did not increase among the oldest individuals.

Conclusions

Education continues to be a significant predictor of health and longevity into old age. That the increase in educational inequalities is greater for mortality than for hospital admissions (our proxy of overall morbidity) may reflect that well-educated individuals gradually have obtained more possibilities or resources to survive a disease than less well-educated individuals have the last four decades.     

Maternal Obesity and Breast‐feeding Practices Among White and Black Women

Despite the increase in obesity among women of reproductive ages, few studies have considered maternal obesity as a risk factor for breast‐feeding success. We tested the hypothesis that women who are obese (BMI = 30–34.9) and very obese (BMI ≥35) before pregnancy are less likely to initiate and maintain breast‐feeding than are their normal‐weight counterparts (BMI = 18.5–24.9) among white and black women. Data from 2000 to 2005 South Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) were used. The overall response rate was 71.0%; there were 3,517 white and 2,846 black respondents. Black women were less likely to initiate breast‐feeding and breast‐fed their babies for a shorter duration than white women. Compared to normal‐weight white women, very obese white women were less likely to initiate breast‐feeding (odds ratio: 0.63; 95% confidence interval (CI) = 0.42, 0.94) and more likely to discontinue breast‐feeding within the first 6 months (hazard ratio (HR) = 1.89; 95% CI: 1.39, 2.58). Among black women, prepregnancy BMI was neither associated with breast‐feeding initiation nor with breast‐feeding continuation within the first 6 months. Because very obese white women are less likely to initiate or continue breast‐feeding than other white women, health professionals should be aware that very obese white women need additional breast‐feeding support. Lower rates of breast‐feeding among black women suggest that they should continue to be the focus of the programs and policies aimed at breast‐feeding promotion in the United States.     

Forecasting age-related changes in breast cancer mortality among white and black US women: a functional data approach

Background: The disparity in breast cancer mortality rates among white and black US women is widening, with higher mortality rates among black women. We apply functional time series models on age-specific breast cancer mortality rates for each group of women, and forecast their mortality curves using exponential smoothing state-space models with damping. Materials and Methods: The data were obtained from the Surveillance, Epidemiology and End Results (SEER) program of the US [1]. Mortality data were obtained from the National Centre for Health Statistics (NCHS) available on the SEER*Stat database. We use annual unadjusted breast cancer mortality rates from 1969 to 2004 in 5-year age groups (45–49, 50–54, 55–59, 60–64, 65–69, 70–74, 75–79, 80–84). Age-specific mortality curves were obtained using nonparametric smoothing methods. The curves are then decomposed using functional principal components and we fit functional time series models with four basis functions for each population separately. The curves from each population are forecast and prediction intervals are calculated. Results: Twenty-year forecasts indicate an overall decline in future breast cancer mortality rates for both groups of women. This decline appears to be steeper among white women aged 55–73 and black women aged 60–84. For black women under 55 years of age, the forecast rates are relatively stable indicating there is no significant change in future breast cancer mortality rates among young black women in the next 20 years. Conclusion: White women have smooth and consistent patterns in breast cancer mortality rates for all age-groups whereas the mortality rates for black women are much more variable. The projections suggest, for some age groups, black American women may not benefit equally from the overall decline in breast cancer mortality in the United States.     

Widening educational disparities in premature death rates in twenty six States in the United States, 1993-2007

Background

Eliminating socioeconomic disparities in health is an overarching goal of the U.S. Healthy People decennial initiatives. We present recent trends in mortality by education among working-aged populations.

Methods and Findings

Age-standardized death rates and their average annual percent change for all-cause and five major causes (cancer, heart disease, stroke, diabetes, and accidents) were calculated from 1993 through 2007 for individuals aged 25–64 years by educational attainment as a marker of socioeconomic status, using national vital registration data for 26 states with consistent educational information on the death certificates. Rate ratios and rate differences were used to assess disparities (≤12 versus ≥16 years of education) for 1993 through 2007. From 1993 through 2007, relative educational disparities in all-cause mortality continued to increase among working-aged men and women in the U.S., due to larger decreases of mortality rates among the most educated coupled with smaller decreases or even worsening trends in the less educated. For example, the rate ratios of all-cause mortality increased from 2.5 (95% confidence interval (CI), 2.4–2.6) in 1993 to 3.6 (95% CI, 3.5–3.7) in 2007 in men and from 1.9 (95% CI, 1.8–2.0) to 3.0 (95% CI, 2.9–3.1) in women. Generally, the rate differences (per 100,000 persons) of all-cause mortality increased from 415.5 (95% CI, 399.1–431.9) in 1993 to 472.7 (95% CI, 460.2–485.2) in 2007 in men and from 165.4 (95% CI, 154.5–176.2) to 256.2 (95% CI, 248.3–264.2) in women. Disparity patterns varied largely across the five specific causes considered in this study, with the largest increases of relative disparities for accidents, especially in women.

Conclusions

Relative educational differentials in mortality continued to widen among men and women despite emphasis on reducing disparities in the U.S. Healthy People decennial initiatives.     

Breastfeeding in the United States

The breastfeeding of US infants born in 1974-76 is analyzed using data form the 1976 National Survey of Family Growth. Life table estimates of the proportion of children breastfed by duration since birth and mean breastfeeding durations are presented. The life tables reported are constructed by standard cohort table methods. To compare life tables for children of mothers in various attribute categories, generalised Wilcoxon tests are used, together with multiple classification analysis for continuation at select durations. Variables considered include mother's age at the birth, ethnicity, educational level, education by ethnicity, region of residence and the child's birth order. Findings are restricted to infants remaining with their mothers for at least 2 months following delivery and surviving as of the survey date in January-September 1976. It is found that the proportion of infants breastfed was increasing rapidly, with the highest rates found among white (39%), college-educated (56%), western (56%) mothers and lowest rates among black mothers (17%) mothers with less than a high school education (19%) and mothers living in the south (24%). By age, the highest proportions are mothers at ages 25-29 (44%), followed closely by the mothers under 25 (29%). The proportions breastfeeding were also found to be higher in urban than in rural areas (38% vs. 28%) and higher at parities 1-2 (29%). A multiple classification analysis of the factors most strongly influencing breastfeeding in 1975 shows educational level to be the strongest single predictor of breastfeeding, followed by western residence and white ethnicity. Age effects were found to correlate strongly with education. Reviewing 1971-1981 changes, the proportion of mothers with less than a college education who breastfed their children increased from 19% to 51% over the decade, while the proportion among college-educated mothers rose from 42% to 74%. For children who were breastfed, the median duration was about 4.5 months. The mean was 5.5 months, with a range from about 3.0 months among black mothers with less than a high school education, to 6.0 months among college-educated white women. The nationwide changes in breastfeeding patterns and duration may confer modest health benefits on current generations of youngsters, although not benefits that are easily measured, since human milk substitutes are routinely subjected to rigourous testing for nutritional adequacy.     

Self-destructive behaviour in the Hungarian population

In Hungary today the mortality rate of middle aged (55-64 years old) men is higher than it was in the 1930s. Within these statistics there are considerable socioeconomic differences, the mortality rate of lower secondary or lower educated middle aged men is 1.45 times higher than among those with higher education. About 40% of these socioeconomic mortality differences can be explained by higher prevalence of risk behaviour in lower socioeconomic groups. According to the results of our national representative survey conducted in the Hungarian population with 12640 persons in 1995, the prevalence of smoking was 45.5% among men and 26.6% among women. In the populaton younger than 45 years old the prevalence of smoking among men was 47.9%, among women 31.9%. Among men there is a clear socioeconomic gradient in smoking, in the number of daily cigarettes, the quantity of spirit consumption in one occasion, among women this socioeconomic gradient is not so obvious. The effectiveness of health promotion programmes depends on effective management of the motivational, psychological determinants of risk behaviour.     

Survival disparities among racial/ethnic groups of women with ovarian cancer: An update on data from the Surveillance,Epidemiology and End Results (SEER) registry

ObjectiveUpdate information on racial disparities in ovarian cancer survival from the Surveillance, Epidemiology, and End Results (SEER) Program.MethodsData on women with epithelial ovarian cancer from the SEER Program between 1995–2015 were collected including; patient ID, age at diagnosis, year of diagnosis, surgery, chemotherapy, radiation, insurance status, region of registry, tumor grade, tumor histology, tumor summary stage, survival months, race/ethnicity, and vital status. Multivariable analyses were performed to examine overall survival, differences in survival by age at diagnosis, by year of diagnosis, risk of not receiving surgery, and risk of 12-month death across racial/ethnic groups.ResultsNon-Hispanic black women (n = 4261) had an increased risk of overall mortality (HR = 1.28, CI: 1.23–1.33) when compared to non-Hispanic white women (n = 47,475), which appears more pronounced among women diagnosed under age 50. Hispanic women (n = 7052) had no difference in survival when compared to non-Hispanic white women (HR = 1.03, CI: 0.99–1.07). Non-Hispanic Asian/PI women (n = 5008) exhibited slightly reduced risk (HR = 0.95, CI: 0.91–0.99) when compared to non-Hispanic white women. Risk of not receiving surgical intervention remains high among non-Hispanic black women and Hispanic women, when compared to non-Hispanic white women. Non-Hispanic black women, non-Hispanic Asian/PI women, and Hispanic women were all at significantly greater risk of dying within the first 12 months of cancer diagnosis when compared to non-Hispanic white women.ConclusionDisparities in survival remain across various racial/ethnic groups, when compared to non-Hispanic white women with ovarian cancer. These disparities should continue to be examined in an effort to decrease such gaps.     

Comparison of Cardiovascular Risk Factors in Obese Blacks and Whites

Blacks are known to have higher blood pressure levels, a higher prevalence of hypertension, and higher body weights than whites. However, the interrelationships of these and other cardiac risk factors have not been analyzed in an obese population. We compared blood pressure (BP) and lipid levels in 174 obese blacks and 939 obese white patients who were entering a weight loss program; we also assessed the effects of weight loss on these factors. Prevalence of treated hypertension was similar in blacks and whites (28% vs. 25%, respectively). In patients not taking BP medication, black women weighed more (108 kg) than white women (102 kg) and black and white males' weights were similar (135 kg vs. 131 kg). Systolic and diastolic BP were similar in black and white women; black males had similar SBP but a significantly lower DBP than white males (83 mmHg vs. 89 mmHg, respectively). Lipid levels were similar in black and white women except black women had lower triglycerides (1.30 mmol/L) than white women (1.58 mmol/L, p<0.05); and black males compared to white males had significantly lower total cholesterol (4.76 mmol/L vs. 5.56 mmol/L), LDL-cholesterol (3.15 mmol/L vs. 3.52 mmol/L) and triglycerides (1.31 mmol/L vs. 2.17 mmol/L, p<0.05). Adult-onset obesity adversely affected a number of cardiovascular risk factors in whites, but not in blacks. Blacks lost significantly less weight (?13 kg) than whites (?19 kg). However, controlling for the difference in weight loss, blacks sustained comparable improvement in lipids and blood pressure, except for TC/HDL-C (whites improved significantly more, ?0.36 kg/m2, than blacks, 0.03 kg/m2). Thus, the impact of obesity on cardiovascular risk factors seems ameliorated in blacks com-pared to whites.
