Table 2 Sensitivity analysis: association of yearly changes in food groups intake with concurrent changes in body weight (A) or waist circumference (B) over 5-year of follow-up - mutual adjustment considering food groups significantly associated with changes in anthropometry

  1. β (95% CI) represents the yearly change in body weight (kg) or waist circumference (cm) associated with increased/decreased consumption of particular food groups (serving/d). The mutually adjusted model was adjusted for covariables used in all multivariable models (time, sex, center, intervention group, age, baseline BMI/WC (depending on outcome) and educational level, as well as yearly measured changes in smoking status and physical activity) and for the other food groups significantly associated with changes in anthropometry
