BMI body mass index, WC waist circumference. Model1: unadjusted. Model2: adjusted for sex and age. Model3 adjusted for Model2 and marital status, alcohol consumption, smoking, physical activity, place of residence,cancer, stroke, psychotic illness and blood glucose. Linear trend test was performed by modeling the median value of each exposure category as a continuous variable in the models
