Abstract

     This survey research by cross-sectional study aimed to determine the prevalence and develop a prediction model for hypertension among the elderly. The study population comprised individuals aged ≥60 years in Yasothon Province. A total of 459 participants were selected using multi-stage sampling. The research instrument was a questionnaire. Descriptive statistics and multiple logistic regression analysis were applied to develop the prediction model. The prevalence of hypertension was 43.6% (95% CI: 39.0–48.2). The prevalence was higher among females (46.3%, 95% CI: 40.3–52.4) than males (39.6%, 95% CI: 32.5–47.0) and increased with age. The final prediction model identified three significant predictors: age, diabetes mellitus, and hyperlipidemia. Individuals aged 70–79 years and ≥80 years had 2.5 and 3.2 times higher odds of hypertension compared with those aged 60–69 years, respectively. Diabetes mellitus increased the risk by 3.5 times, while hyperlipidemia was the strongest predictor with a 5.5-fold increased risk. The model demonstrated a good fit with the empirical data (GOF, p = 0.624) and acceptable discrimination ability (AUC = 0.76; 95% CI: 0.72–0.81). At the optimal cut-off point of 0.39, the model yielded a sensitivity of 71.5%, specificity of 67.2%, and overall accuracy of 69.1%.
