Abstract:Objective To survey and analyze the prevalence rate of hypertension and its main risk factors in adult residents in Qilihe District of Lanzhou City, and to provide a scientific basis for effectively carrying out prevention and control strategies for hypertension. Methods A cluster multi-stage random sampling method was used to select 5,000 permanent residents aged 18 years and above in 9 streets and 6 towns of Qilihe District of Lanzhou City, and then a questionnaire survey was conducted. Data were entered using EpiDate 3.1, and SPSS 25.0 statistical software was used to perform single-factor Chi-square test andmulti-factor unconditional logistic regression analysis. Results A total of 5,000 questionnaires were distributed, and 4,776 valid questionnaires were retrieved, with the effective rate of 95.52%. Among them, there were 2,414 males (50.54%) and 2,362 females (49.46%). The crude prevalence rate of hypertension was 21.94% (95%CI: 20.79%-23.14%), and the standardization rate was 21.45%. Univariate analysis showed that urban and rural areas, age, educational background, body mass index (BMI), waist circumference, alcohol consumption, family history of hypertension, diabetes, and average daily intake of vegetables were related to the occurrence of hypertension. Multivariate logistic regression analysis displayed that rural area (OR=1.577, 95%CI:1.309-1.899), age (OR=1.062, 95%CI:1.057-1.068), BMI (OR=1.584, 95%CI:1.412-1.777), family history of hypertension (OR=1.526, 95%CI: 1.286-1.811), and diabetes (OR=1.772, 95%CI: 1.409-2.229) were risk factors for hypertension. Conclusions The prevalence rate of hypertension in the adults in Qilihe District in 2017 was relatively high. Rural area, age, BMI, family history of hypertension and diabetes were risk factors for hypertension. It is necessary to further control the prevalence rate of hypertension through preventing and controlling the risk factors for hypertension.
