Simple random sampling was used.Sociodemographic characteristics of the respondents were collected, a valid and reliable measureon nutritional knowledge, illness perceptions, and adherence to diet, and a researcher‑mademeasure based on TTM constructs through in‑person interview was applied. Descriptive statisticsand general linear model were utilized for data analysis using SPSS version 25. The significancelevel was considered less than 0.05.RESULTS: Mean and standard deviation of participants was 50.82 ± 8.77 years. Multivariateregression analysis indicated that family income (P < 0.001) and body mass index (P < 0.001) predictednutritional knowledge and adherence to diet, respectively. Decisional balance and self‑efficacyconstructs predicted nutrition knowledge and illness perceptions (P < 0.001). In adherence to diet,overcoming the temptation construct was indicated as the only predictor (P < 0.001).CONCLUSION: Study findings highlighted the necessity of tailoring and implementing interventionsbased on TTM using appropriate strategies to promote quality of HTN management approach innutritional knowledge, illness perceptions, and dietary adherence.
