Age Specificity of Effects of Health Problems on Drinking Reduction: A Lifespan Developmental Analysis

Older adult drinking poses a growing public health concern, especially given the ongoing aging of the United States population. As part of a larger lifespan developmental project contrasting predictors of drinking reductions across different periods of adulthood, we tested age differences in effects of health problems on drinking declines across young adulthood, midlife, and older adulthood. We predicted these effects to be developmentally specific to midlife and older adulthood. We also tested moderation by alcohol use disorder (AUD) symptomatology and by indices of sociodemographic disadvantage (sex and race/ethnicity). Analyses used data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), leveraging NESARC's vast age range (18-90 + ; N = 43,093) and two waves of longitudinal data. Multiple-group cross-lag models tested differences across age groups in cross-lag paths between health problems and alcohol consumption. As hypothesized, health problem effects on drinking reductions were developmentally specific to midlife and older adulthood. However, models testing moderation by AUD symptomatology showed that these adaptive effects of health problems on drinking reductions did not extend to those with one or more AUD symptoms. Little evidence was found for moderation by sex or race/ethnicity. Findings support the notion of health concerns as a pathway to drinking reduction that increases in importance across the adult lifespan. However, given the moderation by AUD symptoms, findings also highlight a need to understand barriers to health-related pathways to drinking reduction among relatively severe midlife and older adult drinkers. These findings hold implications for lifespan developmental tailoring of clinical, public health, and policy interventions.
