Table 4 Structural Equation Model with Follow-up data with Calorie Intake and Leisure Time Physical Activity as mediators between Depression and Body Fat

From: Physical activity and calorie intake mediate the relationship from depression to body fat mass among female Mexican health workers

  1. n = 456
  2. Fit statistics: χ 1=0.05, p = 0.830; RMSEA < 0.001, P(RMSEA < 0.05) =0.903; CFI = 1.0; TLI = 1.0
  3. The model satisfied stability with all eigenvalues inside the unit circle
  4. Model estimated with the asymptotic distribution free method. All covariance parameters between exogenous variables were also included (available as Additional file 1: Table S2). All variables were centered at the mean except body fat at follow-up
  5. *Excludes an item that asked about whether the subject experienced lack of hunger
