Estimated associations between ‘life course SES” group and obesity patterns from multinomial logistic regression models^* in analysis sample (N=12,940) from Wave I (1994-1995) and Wave III (2000-2001) of the National Longitudinal Study of Adolescent Health

^*Gender-stratified, age-adjusted multinomial logistic regression models estimating relative risk ratio of obesity incidence (becoming obese from Wave I to Wave III) or obesity persistence (staying obese from Wave I to Wave III) versus staying non-obese (outcome referent) across the transition from adolescence to adulthood associated with membership in each life course SES group versus “highest overall advantage” (exposure referent)
