Background: Diabetes is the most prevalent disease resulted from metabolic disorders. This study aimed to investigate the effect of training based on health belief model (HBM) on oral hygiene-related behaviors in patients with type 2 diabetes mellitus.
Methods: This study was conducted as an educational randomized controlled trial (single blind) on 120 patients with type 2 diabetes referring to a diabetes clinic selected through systematic sampling, who were assigned to two groups of control (N=60) and intervention (N=60). The data collection tool was a valid and reliable questionnaire based on (HBM) which was completed for both groups before the intervention. Then, the intervention group received 4 sessions of training based on health belief model in one month, and the same questionnaire was completed again after 3 months and data were analyzed using SPSS 20 applying the t-test, paired t-tests, Chi square, Mann-whitney test and Wilcoxon test analysis. The significance level was considered at 0.05.
Results: Three months after the intervention, awareness of the patients and perceived susceptibility, benefits, self-efficacy, internal cue to action and performance in oral and dental hygiene-related behaviors had a significant increase in the intervention group (p<0.05). So that before the intervention, the mean performance score of the intervention and control groups were
2.16±0.71 and 2.28±0.76, respectively, and no significant difference was observed (p> 0.05). However, after the intervention, the mean performance score of the intervention group (3.25±0.49) was significantly more than that of the control group (2.66 ±0.56) (p = 0.001).
Conclusion: Our results suggested that the training the patients with diabetes based on HBM and performing active follow-ups can enhance their skills in the field of oral and dental hygiene-related behaviors. Also, control, monitoring and training follow-up is recommended during these programs.
