The effect of the applying health belief model program of vascular disease preventive in patients with Hypertension and diabetes mellitus at Namon District, Kalasin Province.

Abstract

This quasi-experimental study aimed to investigate the effect of the health belief model program for vascular disease prevention in hypertensive and diabetic mellitus patients in Namon District, Kalasin Province. The sample was 46 patients, which were divided into 2 groups, 23 each. The experimental group received knowledge trainings about dietary behavior and health belief. Two independent populations were used to calculate the sample size. Data was collected by using an interview form before and one week after the experiment, and analyzed for percentage, mean, standard deviation, paired-samples t-test and independent samples t-test with a significance level of 0.05

                The results showed that the averaged knowledge scores of the experimental group before and after the experiment ​​were 0.39 (S.D.=0.11) and 0.92 (S.D.=0.61), respectively, and the mean knowledge scores between the experimental and the comparison group after the experiment were 0.92 (S.D.=0.61) and 0.49 (S.D.=0.11), in order. Both mean knowledge scores were significantly different, p < 0.001. The mean score of dietary behavior to prevent vascular disease of the experimental group before and after the experiment ​​were 3.69 (S.D.= 0.31) and 4.11 (S.D.= 0.28), respectively, and the mean score after the experiment between the experimental and the comparison group were 4.11 (S.D.= 0.28) and 3.65 (S.D.= 0.37), in order; there was a statistically significant difference, p < 0.001. The mean (standard deviation) before and after the experiment of the health belief scores in perceived threat, severity, benefits, and obstacles ​​were 0.39(0.11), 3.91(0.38), 3.98(0.48) and 3.89(0.47), and 0.92(0.61), 4.50(0.44), 4.59(0.32) and 4.50(0.41), respectively. After the experiment between the experimental and the comparison group, the mean values ​​were 4.50(0.44), 4.59(0.32), 4.50(0.41) and 4.71(0.26), and 0.41(0.41), 3.96(0.35), 3.81(0.38) and 4.11(0.34), in sequence. There was a statistically significant difference of the overview of health beliefs (p < 0.05).
