Associations Between Physical Activity And Diabetes Mellitus In Adults Aged 30 Years Old And Above In Chongqing

Objective: Diabetes mellitus is a lifelong concomitant disease that poses a serious health risk.Faced the high diabetes mellitus prevalence and the large population base,it is important to strengthen the promotion and prevention of diabetes mellitus.The purpose to analyze the prevalence of diabetes,physical activity and sedentary situation in Chongqing with different demographic characteristics,to analyze the relationship between physical activity,sedentary leisure time and type 2 diabetes,and provide a scientific basis for the prevention of type 2 diabetes by daily activities.Methods:A total of 21475 residents aged 30 to 79 years were selected as the subjects in Chongqing Province from September 2018 to February2019.The investigation was performed by questionnaire,physical measurement and Biological sample detection.Stratified by gender,descriptive analysis of physical activity status and sedentary leisure status,χ2 test was used to analyze to heterogeneity in basic demographic characteristics between non-diabetics and diabetics.Logistic regression models were used to analyze relationship between 4 types of physical activity,total physical activity,sedentary leisure time and type 2 diabetes mellitus,the used software was SPSS25.0.Results: A total of 2115 patients with type 2 diabetes mellitus were identified with a prevalence of 9.8%,of which 1148 were men and 967 women.The average daily sedentary leisure time was 2.5±1.7h/d,and the average daily total physical activity level was 20.4±12.9 met-h/d.The average daily occupation related physical activity was 11.8±13.0met-h/d,the average daily commute-related physical activity was 1.2±1.6met-h/d,the average daily active-recreational physical activity was 2.3±3.5met-h/d,the average daily housework physical activity was 5.0±5.2 met-h/d.Adjusting related factors,logistic regression analysis showed that the high levels of occupational physical activity was associated with a lower risk of DM compared to occupational physical activity levels of0(OR=0.377,95%CI=0.171～0.832);the middle and high levels of active-recreational physical activity was associated with a higher risk of DM compared to 0 levels of active-recreational physical activity(OR=1.220,95%CI=1.061～1.139;OR=1.477,95%CI=1.008～1.305);Househ old physical activity was associated with a lower risk of DM(OR=791,95%CI=0.674～0.928;OR=0.730,95%CI=0.612～0.870;OR=839,95%CI=0.704～0.999).In men,the middle and high levels of active-recreational physical activity was associated with a higher risk of DM compared to 0 levels of active-recreational physical activity(OR=1.320,95%CI=1.085～1.606;OR=1.238,95%CI=1.037～1.479);the middle and high levels of household physical activity was associated with a lower risk of DM(OR=0.822,95%CI=0.686～0.986;OR=0.761,95%CI=0.615～0.940).In women,household physical activity was associated with a lower risk of DM(OR=0.547,95%CI=0.381～0.784;OR=0.547,95%CI=0.349～0.727;OR=0.534,95%CI=0.373～0.764).The high levels of total physical activity was associated with a lower risk of T2 DM compared to low levels of total physical activity in total population(OR=0.745,95%CI=0.642～0.966).In women,the middle and high levels of total physical activity was associated with a lower risk of DM compared to low levels of total physical activity(OR=0.810,95%CI=0.882～0.962;OR=0.748,95%CI=0.565～0.990).Conclusions:Household activity and high level of occupational activity are protective factors for diabetes.The middle and high levels of active-recreational physical activity was associated with a higher risk of DM compared to 0 levels of active-recreational physical activity in men and total population.High levels of total physical activity were associated with a reduced risk of type 2 diabetes;lsedentary leisure time was not associated with type 2 diabetes risk.Therefore,in addition to total physical activity,it is important to consider the relationship between different areas of physical activity and leisure sedentary status and diabetes when evaluating the impact of physical activity on diabetes and developing intervention strategies.
