A randomized controlled trial of an educational intervention to promote oral and dental health of patients with type 2 diabetes mellitus
Abstract
Abstract 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 by both groups before the intervention. Then, the intervention group received 4 sessions of educational program based on HBM in 1 month, and the same questionnaire was completed again after 3 months and the data were analyzed through SPSS version 20 software with inferential statistics, t-test, paired t-tests, Chi square, Mann-Whitney test, and Wilcoxon test analysis. 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 the performance of oral and dental hygiene in the intervention group increased from 2.16 ± 0.71 to 3.25 ± 0.49 (p = 0.001) after the education. Conclusion Our results suggest that training patients with diabetes based on HBM as well as through active follow-up can enhance their skills in oral and dental hygiene-related behaviors. Controlling, monitoring and follow-up during the program are also recommended. Trial registration Iranian Registry of Clinical Trials, IRCT 2017050733847N1.
