Racial/ethnic health disparities in South Carolina and the role of rural locality and educational attainment.

BACKGROUND: The prevalence of selected health indicators were compared among the Catawba Indians, African Americans, and whites in South Carolina, considering the possible role of rural locality and education. METHODS: Catawba members were respondents of a 1998 survey (N = 808). Other South Carolina residents were respondents of the 1995-1997 Behavioral Risk Factor Survey (4,150 whites and 1,413 African Americans). Prevalence of cardiovascular disease, diabetes, hypertension, overweight, poor health, smoking, physical inactivity, and poor diet were compared among the racial/ethnic groups. Logistic regression analyses were conducted within strata of urban/rural locality and education to determine whether these factors were associated with the adverse health indicators. RESULTS: Both Catawba and African Americans had higher prevalence of diabetes, hypertension, overweight, poor health, physical inactivity, and poor diet than whites. In addition, prevalence of diabetes, poor health, smoking, and poor diet were higher among the Catawba than among African Americans. Restricting the analyses to comparisons within urban/rural locality had little effect, whereas restricting the analyses to comparisons by education level eliminated many of the disparities among those with low education. CONCLUSIONS: Prevalence of chronic disease and adverse health behavior are higher among the Catawba than among other residents of South Carolina, especially compared with white residents.

The modifiable factors contributing to leading causes of death in South Carolina.

In 1996, there were 34,035 deaths in South Carolina. Almost 70 percent of these deaths were due to chronic diseases. There are known ways to prevent chronic diseases from developing or at least delay their developmental process, thereby lengthening years of life. The purpose of this paper is to report modifiable risk factors for mortality related to leading causes of death. The top ten causes of death in South Carolina were obtained from the South Carolina Department of Health and Environmental Control. Estimates of the number of deaths due to certain modifiable risk factors were made using results of a study published by McGinnis and Foege. The percentage of deaths due to each cause was adapted to South Carolina death certificate data from the national estimates. Results indicate that small modifications in individual lifestyles could prevent or delay nearly 50 percent of deaths in South Carolina annually. Tobacco use, diet and physical activity, and misuse of alcohol contribute to the largest number of deaths. Other modifiable behaviors contributing to the 50 percent mortality are microbial agents, toxic agents, firearms, sexual behavior, motor vehicle accidents, and illicit use of drugs. The implication in these findings is that these risk factors for mortality are mainly modifiable. There are many causes of death that may be delayed due to these modifiable risk factors. By looking at preventable causes of death, rather than focusing on traditional causes of death, it becomes clear that prevention strategies are critically important.

Overview of the Diabetes Initiative of South Carolina.

Implementation is underway for many of these programs, and there are descriptions of activities elsewhere in this symposium. The Board recognizes that in dealing with the complications of a chronic disease like diabetes, many years of intense effort will be needed before significant results may be appreciated. Progress will be monitored regularly by the Surveillance Council and SCDCP/DHEC, and modifications of the plan will be made by the Board at intervals after review of the data. We are optimistic that over the next decade, this system will make a significant impact to reduce mortality, morbidity, and costs of diabetes, and the result will be an increased quality of life for people affected by diabetes in South Carolina.

Self-reported prevalence of diabetes and preventive health care practices among people with diabetes in South Carolina.

In conclusion, South Carolina has a higher prevalence of diabetes compared to the national average. Age is a major factor associated with increased prevalence. African Americans had a disproportionately higher prevalence of diabetes relative to white Americans in South Carolina. Compared to the standards of diabetes care recommended by the ADA, health care practice by people with diabetes and health professionals still needs to be improved. Diabetes communication programs, including diabetes education for people with diabetes and health professional education, continue to be necessary for the improvement of diabetes care.

Body fat distribution and race differences in apolipoprotein A1.

OBJECTIVE: This is the first study to assess the role of waist-to-hip ratio in explaining race differences in levels of serum apolipoprotein A1, a protective risk factor for atherosclerosis. METHODS: Linear regression analyses were used in a community-based survey of 3,043 adults (23.5% African-American) to assess associations of race, age, anthropometric measures, education, diabetes, blood pressure medication use, cigarette smoking, and leisure-time physical activity with apolipoprotein A1 levels. RESULTS: Higher apolipoprotein A1 levels were observed among African-American than among white adults (African-American men: +15.6 mg/dl than white men, African-American women: +3.1 mg/dl more than white women; p < 0.05). Waist-to-hip ratio and other variables did not account for race differences among men. African-American women had +8.6 mg/dl higher levels than white women after adjustment for differing distributions of waist-to-hip ratio, age, body mass index and education. Cigarette smoking, physical activity, and medical history accounted for no further differences among women. CONCLUSIONS: Higher levels of obesity indicators and lower educational attainment among African-American women reduced a potentially greater beneficial race difference in apolipoprotein A1. These findings also suggest that other environmental and biochemical factors may play roles in explaining the higher protective levels of apolipoprotein A1 observed among African-American children and adults.

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 multivariable 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.

Trends in mortality and health behaviors: status of white and African-American women.

A substantial proportion of mortality in the United States can be attributed to three major behaviors: using tobacco, maintaining an unhealthy diet, and being physically inactive. Using data from the South Carolina mortality files and Behavioral Risk Factor Surveillance System we were able to document state trends in mortality, cigarette smoking, physical inactivity, and unhealthy dietary practices. We found that, in spite of the declines in heart disease and stroke mortality noted nationally and in the state, the risk factor profiles for most women in South Carolina did not improve. This analysis further suggests that physical inactivity and dietary issues (excess caloric intake, low fruit and vegetable consumption) would be good choices for lifestyle interventions among women in South Carolina, not only because they ultimately affect mortality, but also because they exert interim effects on morbidity, including physical functioning and independence.

Waist-to-hip ratio in a biracial population: measurement, implications, and cautions for using guidelines to define high risk for cardiovascular disease.

Cutoff points for high waist-to-hip ratio (WHR) that may define high risk for cardiovascular disease have been suggested for men (0.95) and women (0.80). The WHRs of groups defined by age, race, and sex among 3,118 South Carolina adults were compared with these cutoff points. Measurement methodology, mean WHRs, and prevalence of elevated WHR in this biracial study population were compared with data from other populations. A review of anthropometric measurement methods used in recent epidemiologic studies indicates that a standard method for measuring waist and hip girth is required before comparisons of mean levels can be valid. The paucity of evidence that a high WHR is associated with cardiovascular disease mortality in black populations, and the high number of women who have an elevated WHR in this and other epidemiologic studies, support the following conclusion: Current WHR cutoff points, which are based on evidence from primarily white populations, may not be appropriate for women, older age groups, and some racial or ethnic groups in the United States.

Community intervention and trends in dietary fat consumption among black and white adults.

OBJECTIVE: This study assessed whether a state public health department could effectively implement an affordable nutrition intervention program at the community level. DESIGN: Cross-sectional data were collected via telephone surveys of 9,839 adults, aged 18 years or older, in 1987, 1989, and 1991 in two South Carolina communities. Nutrition education programs began in 1988 in one community. The other community served as a comparison site. We assessed and compared changes in community levels of dietary fat and weekly meat consumption, salt use, and nutrition promotion awareness with analysis of covariance regression techniques that included race, sex, and age as covariates. RESULTS: We observed favorable changes in most eating behaviors and levels of awareness in both communities. The intervention community experienced greater absolute changes that the comparison community in use of animal fats (-8.9% vs -4.0%; P = .02) and liquid or soft vegetable fats (+8.4% vs +3.6%; P = .04), and in awareness of restaurant nutrition information (+33.0% vs +19.4%; P = .0001). Although the primary type of dietary fat used differed between black and white respondents, we observed significant change among both groups. CONCLUSIONS: These results suggest that community-wide nutrition education programs may have augmented regional or national changes in dietary behavior among white and black adults in the intervention community.

Is race related to glycemic control? An assessment of glycosylated hemoglobin in two South Carolina communities.

To consider the relationship between race and long-term glycemic control, as measured by glycosylated hemoglobin (GHb), we analyzed data from a community-based sample of 3175 adults in the South Carolina Cardiovascular Disease Prevention Project. A clinically meaningful difference for mean GHb levels (10.5 vs 8.4%, P < 0.001) was present between black people and white people reporting diabetes. Similarly, a significant association between race and GHb was present among people reporting "borderline diabetes" or no diabetes. Logistic regression confirmed this finding in all three diabetic categories, however, controlling for insulin use in the diabetic group reduced (P < 0.001) the association between GHb and race. These findings confirm that further improvements in glycemic control are necessary, especially for black patients and that black people not reporting diabetes have higher GHb levels compared to white people, possibly due to undiagnosed diabetes.

Correlates of high-density lipoprotein cholesterol in black and white women.

The relationships of high-density lipoprotein (HDL) cholesterol with body composition, leisure-time physical activity, cigarette smoking, and education were examined in a community-based sample of 480 Black and 1337 White women. Univariate and multivariate analyses indicated inverse associations of HDL with body mass index and waist-to-hip ratio in both groups, and with cigarette smoking and low educational attainment among White women only. Since correlates of HDL cholesterol differ for Black and White women, further investigation of the differences in these correlates is warranted.

Leisure-time physical activity and high-density lipoprotein cholesterol in a biracial community sample.

The purpose of this analysis was to describe the association of leisure-time physical activity and high-density lipoprotein cholesterol levels among a large community sample of African-American and white men and women. Physical assessment of high-density lipoprotein cholesterol, weight, height, waist, and hip measurements were obtained for 3121 randomly selected community participants (969 white men, 1409 white women, 205 African-American men, and 538 African-American women). Leisure-time physical activity was assessed from responses to a standard series of questions about participation in various leisure-time activities. We found an inverse relationship between leisure-time activities and high-density lipoprotein cholesterol levels in African Americans, in contrast to a positive association observed in whites; however, these associations failed to reach statistical significance after controlling for age and body composition. These results confirm a strong association of body composition with high-density lipoprotein cholesterol and support continued interventions designed to reduce overall body weight, particularly upper body weight. The results further suggest that the relationships between some life-style factors and HDL levels may be different among minorities.

Leisure time physical activity: are there black/white differences?

BACKGROUND: Behavioral risk factor surveillance survey data collected during 1984 and 1985 in South Carolina were analyzed. METHODS: This article is based on telephone interviews conducted with 2,005 individuals (431 black, 1574 white), mean age, 45.1 years, selected by random-digit dialing. Information on the type, frequency, and duration of leisure time physical activity was used to estimate leisure time energy expenditure (kcal/week) averaged over the previous month. The median level of leisure time energy expenditure differed significantly (all P less than 0.001) by gender (men = 741, women = 421), age (six categories; youngest, 18-29 years = 780; oldest, 70+ = 301), annual household income (four categories; lowest, less than or equal to $10,000 = 300; highest, greater than $35,000 = 870), body mass index (kg/m2, less than or equal to 24.1 = 601, greater than or equal to 30.1 = 180), and race (black = 301, white = 601). RESULTS: Leisure time energy expenditure generally decreased with increasing age and body mass index and increased with increasing levels of education and income among all race/gender groups. Logistic regression analyses revealed that after adjustment for gender (if applicable), age, income, and body mass index, the variable race made a statistically significant contribution to the model, in the total sample (P less than .03) and for women P less than .001), but not for men. CONCLUSIONS: Our results suggest that blacks living in the South, particularly black women, have lower levels of leisure time physical activity compared with their white counterparts after control for several important confounders.

Perceived morbidity as a determinant of health behavior.

It is hypothesized that perceived morbidity, a concept closely related to perceived vulnerability, is an important determinant of health behaviors. In this cross-sectional study (N = 2740), perceived morbidity was conceptualized as a categorical variable defining six distinct morbidity groups: the hypertension, high cholesterol, angina pectoris, heart attack, stroke and 'morbidity-free' groups. We used analyses of covariance to identify differences in health behaviors between the six groups; the analyses were done separately for middle-aged (40-60 years old) and older ( greater than 60 years old) respondents. Results show that perceived morbidity had a significant effect on fat consumption (P less than 0.001) and on physical activity (P < 0.01). In both age ranges, the morbidity-free group had the highest fat consumption; among the middle-aged respondents, the level of physical activity was significantly lower in the morbidity-free group than in the heart attack group. Furthermore, respondents in the high cholesterol group showed consistently a 'better' health behavior than people in the hypertension group. Overall, these results suggest that the concept of perceived morbidity may be useful in explaining inter-individual differences in health behaviors.
