Sample
NESARC-III included 36,309 noninstitutionalized U.S. civilians 18 years of age and older 12, 13. Respondents completed computer-assisted face-to-face personal interviews between April 2012 and June 2013. NESARC-III employed multistage probabilistic sampling with counties or groups of contiguous counties as primary sampling units, groups of U.S. Census–defined blocks as secondary sampling units, and households within secondary sampling units as tertiary sampling units. Within each household,
Prevalence Estimates of EDs: Lifetime and 12-Month Rates, Overall and by Sociodemographic Characteristics
Prevalence estimates of lifetime AN, BN, and BED diagnoses were 0.80% (SE 0.07%), 0.28% (SE 0.03%), and 0.85% (SE 0.05%), respectively (Table 1). Prevalence estimates of 12-month AN, BN, and BED diagnoses were 0.05% (SE 0.02%), 0.14% (SE 0.02%), and 0.44% (SE 0.04%), respectively (Table 2). Supplemental Table S3 summarizes sensitivity analyses showing the impact of discrepancies between our coding and that of the NESARC-III (listed in Supplemental Table S2) as well as exploring the impacts of
Discussion
This study, with a nationally representative sample of 36,309 adults in the United States who were assessed with lay-administered diagnostic interviews, provides new prevalence estimates of EDs based on DSM-5 criteria. Prevalence estimates of lifetime AN, BN, and BED were 0.80%, 0.28%, and 0.85%, respectively, and 12-month estimates were 0.05%, 0.14%, and 0.44%, respectively. These prevalence estimates are based on our recoding of NESARC-III ED data because inspection of the original NESARC-III
