(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 50 years (Zhang et al., 2008) describing changes over time in drinking status, average volume (Moore et al., 2005; Zhang et al., 2008) and binge drinking (Zhang et al., 2008). However, one study followed participants only through 1992 (Moore et al., 2005) and the other (Zhang et al., 2008) was not conducted in a nationally representative sample. Given the potential problems related to even low-level alcohol consumption among older adults, it is important to fully understand the prevalence of drinking in that population.
