Correlates of knowledge of one's blood pressure and cholesterol levels among older members of a managed care plan.

We examined factors predicting knowledge of one's blood pressure, total cholesterol, and high-density lipoprotein levels (HDL) among older persons who reported a recent blood pressure or cholesterol test. Data come from a self-administered, health risk assessment that was mailed to health plan members, age 55 and older, in a Santa Barbara, California medical group. Despite their universal access to health care and high levels of reported compliance with preventive health care screening practices, 41%, 49%, and 77% of respondents reported that they did not know their blood pressure, cholesterol, or HDL levels, respectively. After controlling for potential confounders, age and low income were inversely associated with the respondents' ability to report each level. In addition, current smoking and obesity were inversely associated with self-reported knowledge of both cholesterol measures. Persons taking medication for hypertension or hypercholesterolemia were much more likely than those not taking medication to be able to report their blood pressure and cholesterol levels. Except for persons currently undergoing treatment for related conditions, these results suggest that a substantial proportion of the older persons at high risk for cardiovascular disease do not know their levels of these important biological risk factors. This lack of knowledge has important implications for public health education, and may hinder risk-reduction efforts among the elderly.

Are older hazardous and harmful drinkers less likely to participate in health-related behaviors and practices as compared with nonhazardous drinkers?

OBJECTIVES: To describe the (1) prevalence of at-risk drinking and participation in health-related behaviors and practices and (2) associations of at-risk drinking with other health-related behaviors and practices among older persons completing a health-risk appraisal for the elderly (HRA-E). DESIGN: Cross-sectional study using data from a self-administered, mailed survey sample. SETTINGS: Persons from three organizations were surveyed: (1) the American Association of Retired Persons; and (2) a large medical group and (3) a community-based senior health center in southern California. PARTICIPANTS: 1,889 persons age 55 years and older. MEASUREMENTS: The HRA-E included items on health characteristics, drinking behaviors (including amount of alcohol use and two alcoholism screening measures: the CAGE (Cut down, Annoyed, Guilty, Eye opener) and Short Michigan Alcoholism Screening Test-Geriatric version (SMAST-G), and participation in selected health-related behaviors and practices. Social drinkers were defined as those who drank fewer than 14 drinks weekly and screened negative on the CAGE (defined as two or more "no" responses) and SMAST-G. Hazardous drinkers drank fewer than 14 drinks weekly and screened negative. Harmful drinkers drank fewer than 14 drinks weekly and screened positive. Possible at-risk drinkers drank 14 or more drinks weekly and screened positive. Least squares regression models were used to assess the effects of hazardous, harmful, and possible at-risk drinking on each of the health-related practices and behaviors. We also conducted these analyses using three other definitions of social, possible at-risk, hazardous, and harmful drinking. RESULTS: Of all respondents, 40% were social drinkers, 3% were harmful drinkers, 2% were hazardous drinkers, and 11% were possible at-risk drinkers. Hazardous, harmful, and possible at-risk drinkers commonly reported driving after drinking or being driven by someone who had been drinking (67%, 76%, and 64% respectively). Harmful and possible at-risk drinkers were more likely than social drinkers to smoke and were less likely to use seatbelts regularly. These findings were observed regardless of how the drinking groups were defined. CONCLUSION: All groups of at-risk drinkers more commonly engaged in selected adverse health-related behaviors and practices than did social drinkers.
