<![CDATA[Background: Hypertension is a major health problem among older adults and can lead to cardiovascular, cerebrovascular, and renal complications. Because many risk factors are modifiable, knowledge of preventive measures may support healthier daily practices and routine blood pressure monitoring. Evidence linking prevention knowledge with directly measured blood pressure status in community-dwelling older adults remains limited in the study setting. Objectives: This study examined the relationship between knowledge of hypertension prevention and blood pressure status among older adults in Sekargadung, Pasuruan, Indonesia. Methods: A quantitative analytical cross-sectional study was conducted from October to November 2025. The accessible population comprised 43 adults aged 60 years or older. A minimum sample of 30 was calculated using Slovin's formula with a 10% margin of error, and participants were recruited purposively. Prevention knowledge was assessed using a 20-item questionnaire, and blood pressure was measured using a sphygmomanometer. Descriptive statistics and Spearman rank correlation were used for analysis. Results: Participants were 61-72 years old, with a mean age of 66.7 years, and 60.0% were men. Nineteen participants had adequate prevention knowledge and 11 had good knowledge. Blood pressure status was normal in 15 participants, prehypertensive in 11, stage 1 hypertensive in three, and stage 2 hypertensive in one. Among participants with good knowledge, 72.7% had normal blood pressure, compared with 36.8% of those with adequate knowledge. Prevention knowledge was significantly associated with blood pressure status (Spearman's rho = 0.383, p = 0.037). Conclusion: Better knowledge of hypertension prevention was associated with a more favorable blood pressure category, although the relationship was weak. Continuous, age-appropriate health education should be combined with regular blood pressure monitoring and practical support for lifestyle change. The cross-sectional design does not establish causality.]]>
