目的探讨昆明市20岁及以上城乡居民劳动强度与2型糖尿病(T2DM)的关系。方法采用多阶段抽样方法,随机抽取昆明市20岁及以上城乡居民5 191人,进行问卷调查、人体测量及生化指标检测。统计学处理采用SPSS统计软件,率的比较用χ2检验,P<0.05为差异有统计学意义。结果调查对象的血压、体质指数(BMI)、腹围、空腹血糖(FPG)、2 h葡萄糖耐量实验(2h-OGTT)、糖尿病患病率均随劳动强度的增加而下降(P均<0.001)。轻体力劳动(43.9%)、中等体力劳动(42.9%)和重体力劳动(13.2%)的糖尿病患病率分别为8.1%、4.5%和1.9%。多因素logistic回归分析,在调整了年龄、性别、肥胖等多种潜在混杂因素之后,轻体力劳动组、中等体力劳动组和重体力劳动组糖尿病的OR值分别为0.73(95%CI:0.44~1.31),0.58(95%CI:0.35~0.94),趋势分析P=0.02。结论体力劳动强度对糖尿病的患病率有明显的保护作用,经常性的适度体力劳动有助于降低居民糖尿病患病风险。
Objective To explore the relationship between labor intensity and type 2 diabetes mellitus (T2DM) in urban and rural areas of Kunming aged 20 years and over. Methods A multistage sampling method was used to randomly select 5,191 urban and rural residents aged 20 years and over in Kunming for questionnaire survey, anthropometric measurement and biochemical detection. Statistical analysis using SPSS statistical software, the rate of comparison withχ2 test, P <0.05 for the difference was statistically significant. Results The blood pressure, body mass index (BMI), abdominal circumference, fasting blood glucose (FPG), 2h glucose tolerance test (2h-OGTT) and prevalence of diabetes decreased with labor intensity (all P <0.001) . The prevalence of diabetes mellitus was 8.1%, 4.5% and 1.9% respectively for light manual labor (43.9%), moderate manual labor (42.9%) and heavy manual labor (13.2%). In the multivariate logistic regression analysis, the odds ratios for diabetes mellitus in light manual workers, moderate manual workers and heavy manual workers were 0.73 (95% CI: 0.44 ~ 0.45) after adjusting for potential confounders such as age, sex and obesity. 1.31), 0.58 (95% CI: 0.35-0.94), trend analysis P = 0.02. Conclusion Physical labor intensity has a significant protective effect on the prevalence of diabetes. Regular and moderate physical labor helps to reduce the risk of diabetes in residents.
