Background: The high prevalence of hypertension in the elderly makes a low-salt diet one of the alternatives that influence blood pressure control. A low-salt diet takes considerable time; hence, family support is needed to achieve low-salt diet adherence in elderly hypertensive patients. The purpose of this study was to determine the correlation of family support with low-salt diet adherence in the elderly with hypertension at Public Health Centre II Sukawati. Method: This study employed a correlational analytical design with a cross-sectional study approach. In this study, the population was the elderly at Public Health Centre II Sukawati, and 147 respondents were recruited through a convenience sampling technique. Data were collected using the Family Support Scale for the elderly (FSS) and low-salt diet questionnaires. Data were analyzed using the Spearman-Rho test. Results: Findings indicated that the statistical test result with the Spearman-Rho test on 147 respondents obtained a significant p-value < 0.001, meaning Ha was accepted and Ho was rejected. This result showed a significant correlation between the two variables, which is the correlation of family support with low-salt diet adherence in the elderly with hypertension. Conclusion: The higher the family support, the higher the level of adherence. Keywords: Elderly, Family Support, Low-Salt Diet Adherence
