  1. * p < .05 ** p < .01 1 The overall effect of time on purging prevalence from 14 to 20 years was not statistically significant, but the comparison between 14 and 20 years was significant at p = .046.
  2. Note. Models are adjusted for body mass index and family income. The effective sample size with these covariates was n = 678 for models with time only and n = 644 for models with depression.
