Background: Diabetes is one of the most important chronic diseases that have a great impact on health as people with diabetes are constantly being reminded of their disease daily; they have to eat carefully, exercise, and test their blood glucose. They often feel challenged by their disease because of its day-to-day management demands and these affect their quality of life. The study aimed at determining the effect of an educational intervention program on the quality of life of Individuals with type 2 Diabetes Mellitus in South East, Nigeria.
Methods: A quasi-experimental controlled study involving three hundred and eighty-two (382) type 2 DM persons recruited from the tertiary health institutions in South East, Nigeria, and randomly assigned to intervention and control groups respectively. Data was collected from the diabetic clinics of the health institutions using the SF - 36 questionnaires. Pretest data collection was done, and thereafter, education on self-care was given to the intervention group. After a 6months follow-up, post-test data were collected from both groups. Analysis was done using an Independent t-test, Analysis of Covariance (ANCOVA), Paired Samples Test, and Spearman rank order correlation at 0.05 alpha level.
Results: The control group indicated significantly higher mean HRQOL scores in most domains of the HRQOL before intervention (t = -1.927 to -6.072, p < 0.05). However, 6 months after the intervention, the mean HRQOL scores of the intervention group increased significantly in all the domains of HRQOL (p < 0.05) with an effect size of 0.14 (Eta squared). A comparison of the two groups shows a statistically significant difference (64.72 ± 10.96 vs. 58.85 ± 15.23; t = 4.349. p = 0.001) after the intervention. Age was inversely correlated with some domains of HRQOL; as age increases, HRQOL decreases in those domains. Gender had no significant influence on HRQOL.
Conclusion: Educational intervention was effective in improving HRQOL in individuals with type 2 DM. Hence, it is recommended for inclusion in all diabetes care plans.
