Prevalence of Hypertension and Associated Factors among Residents Aged ≥18 Years in Ganzhou, China: A Cross-Sectional Study.

Abstract

Background: Reliable epidemiologic data on the present burden of hypertension are needed in developing region-specific strategies since previous studies have suggested that China is lagging in risk factor management.

Objective: The study aimed at exploring the prevalence of hypertension and its associated factors among adult residents in Ganzhou, China. Methodology. A multistage, stratified, and cluster random sampling method was used to conduct the cross-sectional survey. The study selected four county-level districts in Ganzhou City, China, as the investigation area. Permanent residents aged ≥18 years who have settled in the area for 6 months or more were selected. A total of 7430 residents were involved in the study. Univariate and multivariate logistic regression analysis was carried out to identify predictors of hypertension.

Results: The prevalence of hypertension in Ganzhou was 28.5%, and the age-standardized prevalence of hypertension was 22.4%. Univariate logistic regression analysis revealed that multiple variables have a statistically significant effect on the prevalence of hypertension. The elderly (odds ratio [95% CI]: 2.791 [2.594-3.004]), men (1.805 [1.583-2.058]), lower educated (0.848 [0.805-0.893]), a family history of hypertension (4.575 [3.900-5.368]), higher body mass index (1.344 [1.215-1.488]), central obesity (1.532 [1.304-1.799]), and less vegetable intake (1.150 [1.023-1.294]) were the major risk factors for hypertension.

Conclusion: Hypertension is a major public health problem in Ganzhou and requires much effort to reduce its prevalence. An effective multifaceted implementation strategy is highly desirable to combat the emerging burden of hypertension.
