Note. N: number of subjects after selection criteria were applied; SD: standard deviation; BMI: body mass index (kg/m²); SBP: systolic blood pressure; DBP: diastolic blood pressure; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; TG: triglycerides; HbA1c: hemoglobin A1c; FBG: fasting blood glucose; decreased BMI: ΔΔBMI ≥-1.1; stable BMI: ΔBMI -1.1–1.1; increased BMI: ΔBMI ≥ 1.1; ΔBMI = 2011 BMI – 2006 BMI;

^aPaired t-test was used to analyze significant differences between mean serum parameter values in 2006 and 2011;

^bblue highlighting indicates a significant decrease in the mean serum parameter value;

^corange highlighting indicates a significant increase in the mean serum parameter value; n.s., not significant
