<![CDATA[Background: Gout arthritis is an inflammatory joint disorder caused by the deposition of monosodium urate crystals due to hyperuricemia. Recurrent attacks may increase the risk of complications and reduce patients’ quality of life. One factor that may influence recurrence is patients’ knowledge of a low-purine diet. Adequate knowledge is expected to improve dietary adherence, prevent recurrent attacks, and help control uric acid levels. Objective: To examine the relationship between knowledge of a low-purine diet and recurrence among patients with gout arthritis. Methods: This study employed an analytical correlational design with a cross-sectional approach. It was conducted in the working area of Muara Satu Public Health Center, Lhokseumawe City, involving 100 patients with gout arthritis selected using accidental sampling. Data were collected using questionnaires assessing knowledge of a low-purine diet and the recurrence of gout arthritis. Data were analyzed using univariate and bivariate analyses with the chi-square test at a 95% confidence level (α = 0.05). Results: Most respondents had poor knowledge of a low-purine diet (70.0%). Regarding recurrence severity, 52.0% experienced mild recurrence, while 48.0% experienced severe recurrence. The Chi-square test revealed a statistically significant relationship between knowledge of a low-purine diet and gout arthritis recurrence (p = 0.001). Conclusion: Knowledge of a low-purine diet was significantly associated with recurrence among patients with gout arthritis. Continuous and structured health education is needed to improve patients’ knowledge and adherence to a low-purine diet, thereby helping reduce the risk of recurrent attacks.]]>
