Associated Factors of Hypertension in Women and Men in Vietnam: A Cross-Sectional Study

Background: Hypertension is a direct cardiovascular disease risk. It causes a heavy burden on the healthcare system globally. We aim to assess hypertension occurrence and its associated factors among women and men in Vietnam. Methods: A cross-sectional study was conducted from January to February 2019 on 2203 community-dwelling women and men aged 18 years or above. Participants' characteristics, comorbidity, behaviors, and physical measures were evaluated. Hypertension was classified as systolic/diastolic blood pressure >= 140/90 mmHg or using antihypertensive medication. We analyzed data using logistic regression models. Results: The prevalence of hypertension was 24.3% (20.9% in women, 29.1% in men). For women, older age (odds ratio, OR, 6.80-12.41; p < 0.001), income above the poverty line (OR, 0.64; p = 0.008), diabetes comorbid (OR, 2.98; p < 0.001), added salts consumption (OR, 1.80; p < 0.001), overweight/obesity (OR, 1.64; p = 0.005), abdominal obesity (OR, 2.07; p < 0.001) were associated with hypertension. For men, older age (OR, 2.67-5.92; p < 0.001), diabetes comorbid (OR, 2.25; p = 0.010), smoking (OR, 1.38; p = 0.046), and overweight/obesity (OR, 2.18; p < 0.001) were associated with hypertension. Conclusions: Hypertension is prevalent in Vietnamese people. The associated factors of hypertension are varied by gender.
