Abstract: Abstract: Objective To investigate the diabetes risk factors of working age people with different sex and body mass index (BMI）levels in Dagang oilfield. Methods A cross-sectional study was conducted by the Finland diabetes risk score questionnaire to determine the increased risk population, which was divided into diabetes mellitus group and non-diabetes mellitus group. Multivariate logistic regression was used to examine the risk factors of diabetes for different sex and BMI groups. Results The study population comprised 1 995 participants with 985 (49.4%) males. The highest diabetes risk factor of male was the history of high blood glucose (HHBG, OR=3.183, 95%CI: 1.921-5.272), followed by age, aspartate aminotransferase (AST), history of hypertension, history of treatment (HHT) and smoking, with the lowest risk of triglyceride (TG, OR=1.494, 95%CI: 1.033-2.162), while the highest in female was alanine aminotransferase (ALT, OR=2.383, 95%CI: 1.153-4.927), followed by waist circumference (WC), total triglyceride (TG) and age, with the lowest risk of HHBG (OR= 2.081, 95%CI: 0.947-4.571). The risk factors in BMI＜23.9 subgroup for men were the HHBG and TG, while age and TG were risk factors for women. The risk factors in 24.0≤BMI＜27.9 subgroup for men were the age, HHBG and HHT, while age, ALT, and TG were risk factors for women. The risk factors of BMI≥28.0 subgroup were HHBG, HHT, AST and ALT, while only the age for women. Conclusion The main diabetes risk factors of male from high to low are HHBG, age, AST, HHT, smoking and TG, and HHBG is always the risk factor for diabetes in different BMI subgroups. The risk factors of female diabetes are ALT, WC, TG, age, and HHBG in turn. Age is the common risk factor of different BMI subgroups.
