Analytic sample consists of 10,774 individuals measured in adolescence (Wave II, 1996; aged 12–22 years) and adulthood [(Wave III (2001–2002; aged 18–28 years); Wave IV (2008–2009; aged 24–34 years)]. Results were weighted for national representation and standard errors were corrected for multiple stages of cluster sample design and unequal probability of selection. Sex- and age-specific BMI (kg/m2) percentiles of the Centers for Disease Control and Prevention National Center for Health Statistics growth curves were used to classify severe obesity in individuals <20 years of age[46]: severe obesity was classified as BMI≥120% of 95th percentile[47]. For individuals aged ≥20 years of age: severe obesity was classified as BMI≥40 kg/m2. Respondents who exceeded scale capacity at Wave III: 330 lb [n = 12] or at Wave IV: 440 lb [n = 2]) were classified as severely obese at each period. Respondents who were severely obese at baseline were excluded (n=507). Individuals were classified as having incident severe obesity if they were not severely obese at baseline (Wave II) but became severely obese by one of the two follow up periods (Wave III, 2001 or IV, 2009).
Confidence intervals were not estimated because there were no cases of severe obesity among males reporting sexual abuse only.
