Methods: In a cross-sectional study, 250 hypertensive adults were selected in June 2016–2017 from a pool of referred patients to the general clinic at one large teaching hospitals in Iran. They were selected through purposive sampling method. The data collection tools included a demographic questionnaire, self-care agency scale, and self-care behaviors scale. Statistical analysis included simple and multiple (multivariable) linear regression. Results: For dietary sodium reduction, the mean scores (standard deviation) of self-care agency and self-care behaviors were 37.4 ± 10.04 and 36.5 ± 7.8, respectively. Variables with a significant correlation with self-care agency were marital status, age, and the years of hypertension diagnosis (P
