We analyzed data from Wave 2 (W2) of the National Institute of Alcohol Abuse and Alcoholism’s National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) (Grant et al. 2009). NESARC used a complex survey design to yield population-representative estimates of United States adults living in non-institutionalized settings in 2000. Interviews for W2 were conducted from 2004 to 2005 and included 34,653 respondents, reflecting an 86.7% follow-up rate among Wave 1 (W1) participants who were eligible for re-interview (e.g. those who remained alive and noninstitutionalized). W2 respondents have been compared to eligible non-respondents, and no significant differences existed in age, race/ethnicity, gender, socioeconomic status, or lifetime AUD (Grant et al. 2009). The methodology and participants of NESARC have been described previously (Grant et al. 2004a; Grant et al. 2009).
