an interaction between sex and cohort has been noted, with females more likely than males to develop problems with alcohol later in life overall and with later-born females (i.e., those in the younger cohort) more likely to develop problems than those born earlier (Holdcraft & Ianco, 2002). Due to social (e.g., work expectations for males and females) and policy (e.g., insurance) shifts that occur over time, examining service use patterns from a generational, rather than age or cohort, perspective may offer additional insights.
