drinking days in the past month without a preceding conditional branching item. For all surveys except NESARC, binge drinking episodes were initially queried as five or more drinks during one day (NHIS, NHANES, NAS) or one occasion (BRFSS, NSDUH). The NESARC assessed the frequency of consuming five or more drinks for all participants, and four or more drinks for women specifically. For NESARC analyses, we opted to utilize the four-drink threshold for women and five-drink threshold for men for both waves. The NHIS, BRFSS, and NHANES switched to a four-drink threshold for women during the observation period (see Table 1). We examined the prevalence of any binge drinking episode over the past year (NHIS, NESARC, NHANES, NAS) or past month (NSDUH, BRFSS).
