Effects of structured exercises on selected psychological domains in individuals with type 2 diabetes mellitus in Southern Ethiopia institution-based study.

backgroundPsychological disorders are common among individuals with type 2 diabetes mellitus. The effect of exercise training on psychological disorders like anxiety and depression has not been well studied in Ethiopia. The objective of this study was to assess the effect of structured aerobic and resistance exercises on psychological domains among people with type 2 diabetes mellitus in southern Ethiopia.

methodWe began by approaching 97 type 2 diabetic patients who regularly attend follow-up clinics. The 24 study participants were randomly assigned to one of four groups: aerobic exercise (n = 6), resistance exercise (n = 6), combined aerobic and resistance exercise (n = 6), and control group (n = 6). For each arm, the interventions were a structured workout package that was completed without interrupting usual clinical follow-up. The control groups, on the other hand, were kept as follow-up clinical cases with daily routine work. A paired t-test was performed to compare the means and mean differences of each exercise group's pretest and posttest. A Tukey's post hoc test was performed to compare mean differences between groups. The significance level was set at P < 0.05.

resultA more significant change was obtained in the combined aerobic and resistance exercise on anxiety and depression (p = 0.006), social dysfunction (p = 0.009), loss of confidence (p = 0.012) in particular, and psychological wellbeing (p = 0.010) in general. Resistance exercise alone had a significant impact on social dysfunction (p = 0.010), anxiety and depression (p = 0.017), and psychological well-being (p = 0.012) in general. Changes in social dysfunction (p = 0.010), anxiety and depression (p = 0.030), and psychological well-being (p = 0.018) were also influenced by aerobic exercise. The study found no significant change in depression and anxiety among control groups.

conclusionAs a result, the combined effect of aerobic and resistance exercise had a greater influence on improving anxiety and depression, social dysfunction, loss of confidence in particular, and psychological well-being in general among patients with type 2 diabetes. In other words, the present evidence proves the betterment of combined aerobic and resistance exercises alone followed by resistance exercise alone and aerobic exercise alone compared with non-exercise groups seems to upgrade psychological wellbeing by setting up three main benefits named as: (1) anti-anxiety and depression effects; (2) anti-social dysfunction effects; and (3) anti-loss of confidence effects. This suggests that patients with diabetes who exercise regularly enhance their psychological well-being.
