Background: Many studies have reported that diabetes mellitus show the low age tendency. Undiagnosed diabetes patients account for about 25-30% of diabetic patients.

Objective: This study aimed to analyze the epidemiological status and influence factors of prediabetes and diabetes, in order to build screening and intervention system for high-risk population in the primary health care centers.

Methods: A cross-sectional study was conducted. Residents over 35 years old were randomly enrolled from Jun 2016 to Aug 2017 in Electric Health Record (EHR) of Shanghai Minhang District. Data were collected by using questionnaire and physical examination and blood glucose test. Logistic regression was applied to analyze the risk factors for prediabetes and diabetic patients.

Results: A total of 12136 subjects were participated in this screening. Results indicated that 14.54% (n=1765) were diagnosed with diabetes and the prevalence rate in males (17.32%) was significantly higher than in females (12.97%) in each age groups (P< 0.001). Furthermore, 20.69% (n=2511) were diagnosed with prediabetes and males were (23.40%) higher than females (19.16%) (P<0.001). Obesity (BMI≥28)(OR=2.35), family history (OR=1.71), history of cardiovascular disease (OR =1.42), hypertension (OR=1.17), central obesity (OR=1.22), age (OR=1.03), gender (OR=1.31) and sedentary (OR=1.02) were the risk factor for prediabetes or diabetes (p<0.001). In addition, we also found that 54.29% (n= 6589) had over 3 risk factors.

Conclusions: It is concluded that we should pay more attention to population with family history and obesity in the screening of diabetes. Grading management and screening should be carried out in different stages of diabetes. Comprehensive prevention and control should be taken to slow progress in diabetes.
