Hypertension is one of the most prevalent chronic health problems experienced by older adults. The prevalence of hypertension in the elderly tends to increase with age and is mostly associated with unhealthy lifestyle behaviors, especially dietary patterns that do not follow the principles of a hypertension diet. Objective : to analyze the correlation between knowledge and healthy lifestyle patterns in elderly people with hypertension Research Methods/ Implementation Methods : This study employed a cross-sectional design. The sample consisted of 100 respondents aged 60–65 years selected using purposive sampling in the Bengkuring Public Health Center. Data were collected through questionnaires covering respondent characteristics, knowledge level, and dietary behavior. The data were analyzed using the Spearman correlation test with a significance level of 0.05. Results : The results showed that out of the five dietary behavior components observed, only one component showed a significant correlation between knowledge and lifestyle behavior related to caffeine and smoking consumption, with a p-value of 0.011 (<0.05). Elderly individuals who possess better knowledge regarding the effects of caffeine and smoking on hypertension tend to be more cautious in consuming these substances.
