  1. p ≤ 0.05 values are in italic
  2. Model 1: Logistic regression model for studying of relationship between depression and dietary patterns
  3. Model 2: Logistic regression for studying of relationship between healthy dietary pattern and depression with mediation variables
  4. Model 3: Logistic regression for studying of relationship between mediation variables and depression
  5. All of three models adjusted for job, education, marital status, children number, unemployment history in past 5 year, tragic events in past 6 months r, smoking and hookah, depression history, energy expenditure, and physical activity
  6. * Confidence intervals and p values for Hosmer and Lemeshow test that is the criterion of the goodness-of-fit for Logistic regression were nonacceptable
