Objective: To investigate the prevalence and risk factors of impaired fasting glucose (IFG) among adults in northeast China.
Methods: A cross-sectional study was conducted in Jilin Province in 2012. Questionnaires were used to collect information about demographic characteristics, lifestyle factors, and health status from 15,540 residents. Fasting blood glucose (FBG) was measured in the morning after at least 12 hours of fasting, and χ2 tests were performed to compare differences between subjects with and without IFG. Logistic regression was carried out to identify factors influencing IFG occurrence.
Results: There were significant differences in demographic characteristics (age, sex, education, and marriage status), lifestyle factors (smoking, drinking, physical activity, and average sleep duration), and health status (hyperlipidemia, hypertension, and BMI category) between subjects with IFG and without IFG ( P<.05). IFG risk was significantly associated with sex, age, education (senior high school and college), marriage status (single), drinking, hyperlipidemia, hypertension, and BMI category (all P<.05).
Conclusion: In adults in northeast China, risk factors of IFG are sex, age, education (senior high school and college), drinking, hyperlipidemia, hypertension, and BMI category; however, the protective factor of IFG is marriage status (single).
