Ethnic variation in attitudes toward hypertension in adults ages 75 and older.

BACKGROUND: Although critical to the management of hypertension, the attitudes of geriatric patients and possible ethnic group differences in attitudes concerning the disease are poorly understood. METHODS: Data from a 1995-1996 population-based survey of 507 Hispanic American, African American, and non-Hispanic white adults ages 75 and older were used to assess ethnic differences in perceptions regarding the cause, prevention, and treatment of hypertension, as well as associations between perceptions and use of preventive health services. RESULTS: African Americans were more likely to attribute hypertension to health behaviors and stress. In contrast, Hispanic Americans were more likely consider the disease a normal part of aging, whereas non-Hispanic whites were more likely to attribute hypertension to heredity or mechanistic causes. Non-Hispanic whites were less likely to perceive hypertension as preventable, whereas Hispanic Americans were less likely to feel that hypertension was treatable. The odds of having a primary care physician, blood pressure checked, or glaucoma checked were lower among older African Americans and Hispanic Americans than older non-Hispanic whites. The odds of having had a recent physical and of emergency room use were higher among African Americans and lower among Hispanic Americans, in relation to non-Hispanic whites. CONCLUSION: Ethnic differences regarding hypertension were clearly evident in this sample of older adults. In addition, attitudes regarding the cause and treatment of hypertension were found to be associated with both the use and the underuse of preventive health services in all three ethnic groups.

Ethnic variation in the health burden of self-reported diabetes in adults aged 75 and older.

OBJECTIVE: The health burden of self-reported diabetes was compared across three ethnic groups of older adults. METHODS: Analysis of variance and logistic regression were used to compare ethnic differences in the rates of co-morbid chronic health conditions, complications, and disability for older diabetics vs non-diabetics, in a sample of 173 Mexican Americans, 201 African Americans, and 181 non-Hispanic whites, all aged 75 and older. RESULTS: The prevalence of self-reported diabetes was significantly higher in older Mexican Americans (17.6%) and African Americans (16.4%) than in non-Hispanic whites (8.5%). In all three ethnic groups, and after controlling for sociodemographic characteristics, diabetics were found to be generally at higher risk for chronic conditions such as heart disease, stroke, and hypertension, circulation and foot problems, obesity, and impaired vision and activities of daily living. Multivariate analyses indicated that the burden of diabetes appeared to be greatest among non-Hispanic white diabetics. We suggest that this is the result of higher diabetes-mortality rates among minority diabetics at earlier ages. CONCLUSIONS: Diabetes is known to be increasing in prevalence and incidence, particularly among the elderly, the fastest growing segment of the population. Our findings indicate that regardless of ethnicity, diabetes carries an increased burden that affects both the functioning and the quality of life of older adults.
