Two cross-sectional studies (Dawson et al., 2015; White et al., 2015) examined time-trends in adults ages 65+ in relation to several measures of drinking including prevalence of lifetime abstention (Dawson et al., 2015; White et al., 2015), former drinking (Dawson et al., 2015), current drinking (Dawson et al., 2015; White et al., 2015), binge drinking (Dawson et al., 2015; White et al., 2015), average volume (Dawson et al., 2015), quantity (White et al., 2015), and frequency (Dawson et al., 2015; White et al., 2015). However, the study by Dawson et al. was not gender-specific and neither study considered effects of age or birth cohorts. Three cross-sectional studies in adults ages 65+ included analyses that simultaneously considered calendar time, age, and birth cohort (age-period-cohort analyses) in relation to binge drinking (Keyes and Miech, 2013) or both average volume and binge drinking (Kerr et al., 2009; Kerr et al., 2012). However, other measures of drinking were not considered. Longitudinal studies published in the 2000s (Moore et al., 2005; Zhang et al., 2008) followed birth cohorts for 20 (Moore et al., 2005) to
