Analysis of Type 2 Diabetes Prevalence and Its Influencing Factors of Community Residents in Chengguan District of Lanzhou

Objectives To understand the type 2 diabetes prevalence and determine its risk factors of the community residents so as to provide theoretical basis for the prevention and control of diabetes in Chengguan district of Lanzhou city.

Methods A stratified sampling method was used to randomly select 4 917 urban residents above the age of 15, Men and women accounted for 48.7 percent and 51.3 percent respectively. Questionnaire survey and blood glucose detection was used to investigate the prevalence and possible risk factors of diabetes mellitus. Univariate analysis and logistic regression analysis were used to process the data.

Results The prevalence rate of type 2 diabetes among residents in Chengguan district of Lanzhou city was 4.2%. The univariate analysis showed that influencing factors of diabetes included age (χ²=137.420; P < 0.01), weight (χ²=37.676; P < 0.01), marital status (χ²=62.031; P < 0.01), educational level (χ²=49.888; P < 0.01), occupation (χ²=104.199; P < 0.01), breakfast intake per week (χ²=21.711; P < 0.01), fruit intake per day (χ²=15.458; P=0.001), milk and dairy products consumption per day (χ²=10.686; P=0.014), sweets and pastries (χ²=21.349; P < 0.01), smoking (χ²=10.181; P=0.017), passive smoking (χ²=9.437; P < 0.01), mental status (χ²=31.058; P < 0.01), mood (χ²=19.081; P < 0.01), weekly physical activity frequency (χ²=30.844; P < 0.01) and daily meditation time (χ²=12.082; P=0.017). The multivariate logistic regression analysis showed that age (OR_18~=0.183, P < 0.01; OR_35~=0.454, P=0.002; OR_45~=0.634, P=0.033), occupation (OR_retirement=1.739, P=0.037), milk and dairy products intake (OR_{>300 g}=2.317, P=0.003) emotion (OR_blankness=1.977, P=0.005; OR_depression=1.866, P=0.017; OR_anxiety=1.804, P=0.011) were the main risk factors for diabetes, but fruit intake (OR_{< 100 g}=0.512, P=0.009; OR_{(100~200 g)=}0.442, P=0.001; OR_{>200 g}=0.485, P=0.011) may be the protective factors for diabetes in Chengguan Dietrict residents.

Conclusions The strategy of comprehensive prevention and control for diabetes of local residents should be implemented from the aspects of lifestyle, reasonable diet and mental health in Chengguan District of Lanzhou city.
