Background: One of the most important causes of cardiovascular disease is hypertension. Lifestyle modification has been emphasized in preventing and controlling blood pressure. This research aimed to determine the effect of educational intervention by application of PRECEDE‐PROCEED model on lifestyle change in hypertensive patients in the villages of Fasa City, Fars Province, Iran.Methods: This research is a quasi‐experimental study that was conducted on 300 hypertensive patients in 2020–2021. Data gathering tools were a demographic information questionnaire, a questionnaire based on the PRECEDE‐PROCEED model, and a lifestyle questionnaire (LSQ). The educational intervention consisted of ten sessions lasting 45 or 50 min. Before and 6 months after the educational intervention, the two groups each completed a questionnaire. The systolic and diastolic blood pressure (DBP) levels, as well as physical exercise and health variables, nutrition and weight control, mental health, and spiritual health were measured before and 6 months after the educational intervention.Results: The results showed that there was no significant difference between the two groups before in cues of PRECEDE‐PROCEED model; however, the experimental group had a significant increase in cues of PRECEDE‐PROCEED model 6 months after the intervention. The results showed that the experimental group had a significant increase 6 months after the intervention in terms of physical exercise and health variables, nutrition and weight control, mental health, and spiritual health. The mean blood pressure (both diastolic and systolic) in the experimental group was significantly reduced after the intervention.Conclusions: The study’s results showed the effectiveness of an educational intervention based on the PRECEDE‐PROCEED model on lifestyle change in hypertensive patients. It also highlights the need to pay further attention to the education aimed at controlling hypertension through a healthy lifestyle and correct behavioral habits.
