Model I: FPG change (crude model). Model II: model I+baseline measurements of current smoking, family history of diabetes, education, BMI, WC, TG/HDL-C ratio and its change, TC/HDL-C ratio and its change, lipid drug and hypertension change categories. Model III: model II+2-hPCG change.
We defined the hypertension change category based on the first (1999–2001) and second (2002–2005) examination (yes/yes, yes/no, no/yes and no/no).
*Multivariate Cox analyses were conducted using age as timescale; 1SD change in FPG: 0.5 mmol/L; 1SD change in 2-hPCG: 1.57 mmol/L; 1SD change in baseline value of WC: 11.5 cm.
†Covariates with p value <0.05 are shown.
2-hPCG, 2 h post-challenge plasma glucose, mmol/L; AIC, Akaike information criterion; BMI, body mass index; FPG, fasting plasma glucose, mmol/L; HDL-C, high-density lipoprotein cholesterol; TC, total cholesterol; TG, triglycerides; WC, waist circumference.
