OBJECTIVE: A 14-year multiwave panel design was used to examine relationships between longitudinal alcohol-consumption patterns, especially persistent moderate use, and change in health-related quality of life among middle-aged and older adults. METHOD: A nationally representative sample of 5,404 community-dwelling Canadians ages 50 and older at baseline (1994/1995) was obtained from the longitudinal National Population Health Survey. Alcohol-consumption patterns were developed based on the quantity and frequency of use in the 12 months before the interview. Health-related quality of life was assessed with the Health Utilities Index Mark 3 (HUI3). Latent growth curve modeling was used to estimate the change in HUI3 for each alcohol pattern after adjusting for covariates measured at baseline. RESULTS: Most participants showed stable alcohol-consumption patterns over 6 years. Persistent non-users, persistent former users, those decreasing their consumption levels, and those with unstable patterns (i.e., U shaped and inverted U shaped) had lower HUI3 scores at baseline compared with persistent moderate drinkers. A more rapid decline in HUI3 scores than that observed for persistent moderate users was seen only in those with decreasing consumption (p < .001). In a subgroup identified as consistently healthy before follow-up, longitudinal drinking patterns were associated with initial HUI3 scores but not rates of change. CONCLUSIONS: Persistent moderate drinkers had higher initial levels of health-related quality of life than persistent nonusers, persistent former users, decreasing users, U-shaped users, and inverted U-shaped users. However, rates of decline over time were similar for all groups except those decreasing their consumption, who had a greater decline in their level of health-related quality of life than persistent moderate users.
OBJECTIVE: This study examined level of wine consumption and total mortality among 802 older adults ages 55-65 at baseline, controlling for key sociodemographic, behavioral, and health status factors. Despite a growing consensus that moderate alcohol consumption is associated with reduced total mortality, whether wine consumption provides an additional, unique protective effect is unresolved. METHOD: Participants were categorized in three subsamples: abstainers, high-wine-consumption moderate drinkers, and low-wine-consumption moderate drinkers. Alcohol consumption, sociodemographic factors, health behavior, and health problems were assessed at baseline; total mortality was indexed across an ensuing 20-year period. RESULTS: After adjusting for all covariates, both high-wine-consumption and low-wine-consumption moderate drinkers showed reduced mortality risks compared with abstainers. Further, compared with moderate drinkers for whom a high proportion of ethanol came from wine, those for whom a low proportion of ethanol came from wine were older, were more likely to be male, reported more health problems, were more likely to be tobacco smokers, scored lower on socioeconomic status, and (statistical trend) reported engaging in less physical activity. Controlling only for overall ethanol consumption, compared with moderate drinkers for whom a high proportion of ethanol came from wine, those for whom a low proportion of ethanol came from wine showed a substantially increased 20-year mortality risk of 85%. However, after controlling for all covariates, the initial mortality difference associated with wine consumption was no longer significant. CONCLUSIONS: Among older adults who are moderate drinkers, the apparent unique effects of wine on longevity may be explained by confounding factors correlated with wine consumption.
PURPOSE: To examine the association between alcohol use and self-reported health status. In particular, we sought to determine whether moderate drinkers are more likely to self-report above-average health status compared with other current drinkers, former drinkers, and lifetime abstainers. DESIGN: Cross-sectional survey. SETTING: Continental United States. SUBJECTS: The sample adult component of the 2002 U.S. National Health Interview Survey (n = 31,044), representative of the U.S. noninstitutionalized civilian household population. MEASURES: Dichotomous measure of above-average self-reported health status relative to all other health states. Several measures characterized alcohol use patterns (i.e., continuous and categorical measure of alcohol use, a proxy measure of problem drinking, former drinking, lifetime abstaining). Chronic health conditions and various demographic and lifestyle factors were included as covariates in all regression models. RESULTS: For both men and women, current moderate drinkers had the highest odds (OR = 1.27 for men, p < .01; OR = 2.03 for women, p < .01) of reporting above-average health status compared with other current drinkers, former drinkers, and lifetime abstainers. The odds dropped to 1.12 and 1.34, respectively, when all past-year drinkers were collapsed into a single group. CONCLUSION: Moderate alcohol consumption was associated with the highest odds of reporting above-average health status, even after controlling for chronic health conditions and demographic and lifestyle factors associated with health.
