  1. 1- Null hypothesis of no difference between tertiles of dietary pattern: general linear model for interval response variables, logistic regression for binary variables (complete case analysis n = 933).
  2. Model 1: unadjusted estimates (response variable as in column 1, regressor is categorical variable for dietary pattern in tertiles).
  3. Model 2: for BMI, overweight and WC response variables: adjusted for age, total energy intake, physical activity level (% of low, medium and high intensity daytime activities); for blood pressure (systolic and diastolic), high blood pressure and hypertension response variables: adjusted also for anthropometry (BMI and WC).
  4. Model 3: as in model 2 but in addition adjusted also for socio-economic variables: economic level of household, profession of father, education of father, mother working outside the home, education of mother, whether or not subject is attending school at time of survey.
  5. 2- For females, P-value for unadjusted association is from chi-square test (also taking into account sampling design), as no estimates could be obtained for logistic regression models due to observed null prevalence in third tertile (and thus no raw and/or adjusted p-values).
