  1. * = insulin use was significantly associated with T2DM in chi-square test, however, it was not inserted in logistic regression as adjust; OR = odds ratios; ORadj1 = odds ratio adjusted by gender and skin color; ORadj2 = odds ratio adjusted by gender, skin color and insulin use; ORadj3 = odds ratio adjusted by gender, skin color, age and waist-to-hip ratio; 95%CI = 95% confidence interval; T2DM = type 2 diabetes mellitus; PAL = physical activity level; M. Active = moderately active
