Standardized regression coefficients calculated as b_i × S_Xi/S_Y. BMI body mass index, WC waist circumferences, HC hip circumferences, WrC wrist circumferences, WHR waist to hip ratio, WHtR waist to height ratio, FMI fat mass index. Model 1: unadjusted, Model 2: Adjusted with age, CVD history, socio-economic index, Model 3: adjusted with age, CVD history, socio-economic index and physical activity (MET score), dietary intake (energy intake Kcal/day).

Bold values are less than 0.05 and are statistically significant.
