Abstract：Objective To investigate the prevalence rate of hypertension and its main influencing factors among residents in Lujiang County, Hefei City, Anhui Province in 2014, so as to provide evidence for developing hypertension prevention and control measures. Methods A multi-stage stratified random sampling method was used to select 3 towns in Lujiang County in July 2014, then 3 communities were randomly selected from each town and 10 villages from each community. A questionnaire survey and physical examinations were conducted among residents aged 18 years and above. Univariable and multivariable unconditional logistic regression analysis was used to determine the influencing factors of hypertension. Results A total of 2,270 residents participated in the survey, and 2,262 eligible ones were enrolled for final analysis, with the response rate of 99.65%. The prevalence rate of hypertension in the residents aged 18 years and above in the 3 towns of Lujiang County was 39.52%, and the standardized prevalence rate was 24.57%. Univariable logistic regression analysis showed that gender, age, education level, marital status, occupation, average annual household income, alcohol consumption, family history of hypertension, physical exercise, body mass index (BMI) and the distance between the town and He’an highway (namely, traffic noise) were associated with hypertension (P<0.05), of which advanced age, unhappy marriage, alcohol consumption, family history of hypertension, high BMI and traffic noise were the risk factors of hypertension, while the male, high education level, occupation, high average annual household income and physical exercise played the protective roles. Multivariable logistic regression analysis showed that age, occupation, average annual household income, alcohol consumption, family history of hypertension, physical exercise and BMI were correlated with hypertension (P<0.05), of which the odds ratios and 95% confidence intervals were 3.282 (2.711-3.973), 0.920 (0.848-0.999), 0.878 (0.826-0.935), 1.338 (1.072-1.671), 1.648 (1.340-2.027), 0.699 (0.565-0.866) and 1.922 (1.684-2.194) respectively. Advanced age, alcohol consumption, family history of hypertension and high BMI were the risk factors of hypertension, while occupation, high average annual household income and physical exercise played the protective roles. Conclusions The prevalence rate of hypertension in the residents of Lujiang County is high. Advanced age, alcohol consumption, family history of hypertension and high BMI are the risk factors of hypertension, whereas occupation, high average annual household income and physical exercise are the protective factors.
