Objective:To investigate the factors related to insulin resistance and islet β cell secretory function in subjects with normal glucose tolerance(NGT).Methods:Insulin resistance and islet β cell secretory function were estimated by Homeostasis Model Assessment in 2120 NGT subjects.Results:(1)ANOVA showed that there were significant differences in Homa-IR and Homa-β cell among different age groups(P<0.05).(2)t test indicated that there were significant differences in HOMA-IR and HOMA-β cell in overweight/obesity group
central obesity group
high TG group and hypertension group compared with their control groups respectively(P<0.01).(3)Stepwise regression revealed that the main factors influencing HOMA-IR and HOMA-β cell included age
BMI
waist circumference
TG and diastolic blood pressure.Conclusion:In NGT population
IR is aggravating with the age
BMI
waist circumference
TG and blood pressure;islet β cell secretory function is weakening with aging
while it is enhancing with BMI
waist circumference
TG and blood pressure to maintain normal glucose tolerance.
