The Relationship between Pender's Health Promotion Model Constructs and Applying Nutritional Supplements in Patients with Hypertension

This study aimed to investigate the relationship between Pender's Health Promotion Model constructs and applying nutritional supplements in patients with hypertension in rural areas of Isfahan Township, Iran.

In a cross-sectional study, 233 patients with high blood pressure were selected from rural health centers in Isfahan Township. Patient’s dietary intake was assessed by a 3-day dietary questionnaire, and cognitive factors and a commitment to nutritional approach with Pender Health Promotion Model. The relationship between dietary intake and nutritional approach was studied as well.

There was an inverse and significant relationship of 0.316 between sodium intake and knowledge (P < 0.001). Moreover, there was a significant negative correlation of 0.121 between the benefit score and the sodium intake (P = 0.002), but no relationship between other criteria (perceived self-efficacy, behavioral sensation, status affecting, and social support) and sodium intake.

The findings of this study showed that there was a significant relationship between Pender Health Promotion Model and nutritional approaches for controlling blood pressure. Therefore, it is recommended to use Pender Health Promotion Components in health units associated with hypertension.
