Background: Nutrition is considered as the most important in hypertension control however, little information is available about the nutritional status of hypertensive patients in our country. This study was aimed to determine the predictive power of perceived benefits, barriers, self efficacy and knowledge from fat intake and received dietary energy.
Material and Methods: This cross-sectional study was conducted on 671 rural hypertensive patients with using multistage random sampling method in Ardabil city in 2013. Data were collected by a valid and reliable questionnaire with interview method. Nutritional data were extracted by Nutritionist 4 software and analyzed the SPSS 18 software using Pearson correlation, multiple linear regressions, ANOVA and independent T-test.
Results: the mean of total fat, saturated fat and energy were 92.1±27.1, 32.3±9.7 and 2539.4±398.9 respectively. Total fat, saturated fat and energy had a negative significant correlation with perceived benefits and self efficacy and a positive significant correlation with perceived barriers. Perceived barriers, benefits, efficacy and knowledge predicted 20.9% of the energy change variations, 32.42% of the changes in saturated fat intake and 25.7 of the change in fat intake.
Conclusions: Dietary perceptions in the framework of perceived benefits, barriers, self-efficacy and knowledge could explain of total fat and saturated fat and energy intake in acceptable range.
