β-coefficient was calculated with the use of multiple linear regression analysis (forward). †Independent variables included in the regression model: baseline 25(OH)D level, age, sex, FH of diabetes, change in BMI, change in WHR, change in SBP, change in TG, and change in TC, physical activity, smoking status, and alcohol consumption during follow-up. 25(OH)D: 25-hydroxyvitamin D; FH: family history; WHR: waist/hip ratio; BMI: body mass index; SBP: systolic blood pressure; TC: total cholesterol; TG: triglyceride; HOMA-IR: homeostasis model of assessment for insulin resistance index; ISIcomp: insulin sensitive index composite; ΔI30/ΔG30: the ratio of the incremental insulin to glucose responses over the first 30 min during the OGTT. |
