Simple random sampling was used.<br />Sociodemographic characteristics of the respondents were collected, a valid and reliable measure<br />on nutritional knowledge, illness perceptions, and adherence to diet, and a researcher‑made<br />measure based on TTM constructs through in‑person interview was applied. Descriptive statistics<br />and general linear model were utilized for data analysis using SPSS version 25. The significance<br />level was considered less than 0.05.<br />RESULTS: Mean and standard deviation of participants was 50.82 ± 8.77 years. Multivariate<br />regression analysis indicated that family income (P < 0.001) and body mass index (P < 0.001) predicted<br />nutritional knowledge and adherence to diet, respectively. Decisional balance and self‑efficacy<br />constructs predicted nutrition knowledge and illness perceptions (P < 0.001). In adherence to diet,<br />overcoming the temptation construct was indicated as the only predictor (P < 0.001).<br />CONCLUSION: Study findings highlighted the necessity of tailoring and implementing interventions<br />based on TTM using appropriate strategies to promote quality of HTN management approach in<br />nutritional knowledge, illness perceptions, and dietary adherence.<br /><br /> https://jehp.mui.ac.ir/article_28419_383b8db4df9294254ed8fe408268b7a7.pdf
