Abstract:
Objective To investigate the prevalence and influencing factors of diabetes mellitus among community population in Songjiang District of Shanghai， and to provide scientific basis for prevention and treatment of diabetes mellitus.
Methods Based on the baseline data of the Shanghai Suburban Adult Cohort （2016‒2017） and local medication database， the prevalence of diabetes in the cohort was described， and the influencing factors for the prevalence of diabetes in different genders were analyzed.
Results Among 35 928 participants， males accounted for 40.57%， and the median age was 58 years old. There were 5 342 diabetic patients with a crude prevalence rate of 14.87% and the standardized prevalence rate of diabetes mellitus was 7.57%. The prevalence rate of diabetes in males （15.81%） was significantly higher than that in females （14.23%， P<0.001）. Multivariate logistic regression analysis showed that the following factors were associated with high risk of diabetes mellitus in males： 40‒59 age group （OR=7.111，95%CI：4.900‒10.320）， 60‒74 age group （OR=8.994，95%CI：6.154‒13.144）， family history of diabetes （OR=3.369，95%CI：2.963‒3.83）， overweight （OR=1.272，95%CI：1.123‒1.439）， obesity （OR=1.912，95%CI：1.623‒2.252）， hypertension （OR=1.685，95%CI：1.512‒1.877）， and dyslipidemia （OR=1.396，95%CI：1.263‒1.542）. In females， the high risk of diabetes was associated with： 40‒59 age group （OR=2.718，95%CI：1.838‒4.02）， 60‒74 age group （OR=3.517，95%CI：2.34‒5.286）， family history of diabetes （OR=3.071，95%CI：2.761‒3.416）， overweight （OR=1.254，95%CI：1.125‒1.398）， obesity （OR=2.018，95%CI：1.764‒2.308）， central obesity （OR=1.515，95%CI：1.357‒1.692）， hypertension （OR=2.128，95%CI：1.929‒2.347）， dyslipidemia （OR=1.506，95%CI：1.379‒1.644）， exercise （OR=1.241，95%CI：1.137‒1.355）， and menopause （OR=1.967，95%CI：1.693‒2.286）.
Conclusion The prevalence rate of diabetes is high in Shanghai， and the related factors are different in different gender groups.
