Limited knowledge regarding CHD risk factors can reduce awareness and negatively affect preventive behaviors. This study aimed to analyze the relationship between knowledge and coronary heart disease prevention behavior among residents of Gayam Village, Gayam District, Bojonegoro Regency.

A total of 95 respondents were selected using simple random sampling. Data were collected using structured questionnaires and processed through editing, coding, scoring, and tabulation. Statistical analysis was conducted using the Spearman Rho test. The results showed that 68.4% of respondents had insufficient knowledge regarding coronary heart disease prevention, while 86.3% demonstrated inadequate preventive behaviors. Statistical analysis revealed a significant relationship between knowledge and coronary heart disease prevention behavior, with a p-value of 0.000, indicating rejection of the null hypothesis. The correlation coefficient (r = 0.488) showed a moderate positive correlation, meaning higher knowledge levels were associated with better preventive behaviors.
