^aModels were multiple linear regression with statistical significant associations at p < 0.05. All analyses were controlled for age, total calorie intake, physical activity, BF%, medicine status, alcohol intake, smoking status and menopausal status. β, Unstandardized Beta;

^β*,standardized coefficient; R2, Adjusted R square.
