  1. aFrequency of self-weighing was square root transformed for the regression model. Least square means and their 95% confidence levels were squared to back calculate to the unit of reported times self-weighing per week
  2. bDifferent from the reference level at p < 0.05
  3. cAdjusted for Age, Ethnicity/Race, Education and Income
  4. dEstimate may not be reliable due to small numbers of males with eating disorder diagnosis
