Co-occurring alcohol use and anxiety disorders is common in older adults and contributes to poor health
outcomes, higher health care utilization, heightened mortality, and social dysfunction in later life. Although
there are several proposed theoretical explanations for the association between drinking and mental health
disorders (e.g., the precipitation model, the self-medication model, and the mutual maintenance model), few
studies have tested the longitudinal time-dependent relationship between alcohol use and anxiety disorders
in later life, in part, because longitudinal studies are limited. Better understanding of the temporal sequence
of the relationship between alcohol use and anxiety disorders will have implications for improving
prevention and treatment programs for at-risk drinking and anxiety in the older population.
