Analyses adjusted for age, kcal/day, alcohol consumption, smoking, education level, income level, occupation and hypertension. In addition, the analyses stratified by BMI and WHR were adjusted for physical activity and for each other; the analysis stratified by physical activity was also adjusted for BMI and WHR.
