ABSTRACT

Objective To understand the prevalence and disease distribution of migrants within the water source area of the Middle Route Project of South-to-North Water Diversion Project and analyze the influencing factors. Methods By multi-stage stratified cluster sampling method, 307 immigrants and 676 immigrants were selected from Danjiangkou reservoir area, Shiyan city, Hubei Province. Results The prevalence of chronic diseases among in-migration was 51.8%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and diabetes. The prevalence of chronic diseases among out-migration was 65.1%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and bronchitis. The rate of chronic disease, the rate of two weeks and the rate of two weeks' visit were higher than that of emigration(all P<0.05). The results of multivariate analysis showed that the factors influencing the chronic diseases of immigrants were 60 years old (OR=59.928，P<0.001), unsatisfied family income (OR=0.377, P=0.002) and poor economic status (OR=0.517, P=0.028). The factors influencing the chronic diseases of immigrants were 60 years old (OR=26.190, P<0.001), smoking (OR=1.856,P=0.004), unsatisfactory family income (OR=0.598,P=0.029) and poor economic status (OR=0.460,P<0.001). Conclusions The prevalence of migrants within a high level is at a high level. Actually raising the income of immigrants is conducive to improving the health condition of immigrants.
