Abstract
Abstract
Background
Cardiovascular diseases (CVD) are the most important cause of death in many countries of the world, including Iran. This study aimed to investigate the effect of educational intervention based on the Health Belief Model (HBM) on the promotion of nutritional behaviors to prevent CVD among the all people (aged 30–59 years).
Methods
This semi-experimental study was conducted on all people (aged 30–59 years) referring to the primary healthcare centers of Jahorm city, southern Iran, from September 2021 to July 2022. In this study, 100 participants (50 participants for the intervention group and 50 for the control group) were selected using a multistage cluster random sampling method. The data collection tool was a questionnaire with confirmed validity and reliability. Also, the food consumption frequency checklist was used. The educational intervention included holding four sessions, each lasting for 60 min. The methods used for training included lectures, questions and answers, and group discussions. Before the intervention and three months after, the intervention and control groups completed the questionnaire. The obtained data were analyzed by SPSS 17.
Results
after the educational intervention, the mean score of knowledge (4.84 ± 0.84; 2.76 ± 1.41; p < 0.001), perceived susceptibility (9.52 ± 1.81; 8.76 ± 1.9; p = 0.004), perceived severity (14.78 ± 1.66; 13.80 ± 2.23; p = 0.015), perceived benefits (10.66 ± 1.79; 7.52 ± 1.99; p < 0.001), perceived barriers (5.92 ± 2.81; 12.68 ± 10.24; p < 0.001) and practice (178.78 ± 14.35; 147.36 ± 13.19; p < 0.001) showed a significant difference between the intervention and control groups.
Conclusion
The results showed that the educational intervention effectively improved people (aged 30–59 years) knowledge and HBM constructs to prevent CVD. Also, improving people’s performance regarding CVD prevention behaviors will be successful by implementing an educational intervention based on the HBM.
