RESUMEN
BACKGROUND: The present study focuses on comparing the effects of home-based (HB) and group-based (GB) physical activity on mental health in a sample of older adults in Shahr-e-kord. METHODS: In this quasi-experimental study, a twice-weekly physical activity program for 2 months was provided either individually at home or in a group format for 181 people who were divided into two groups (HB and GB). The outcome, mental health, was measured with the 28-item General Health Questionnaire (GHQ-28). RESULTS: Mental health status improved after participation in the physical activity program. The decrease in GHQ-28 total score in GB group, 3 months after intervention, was 3.61 ± 2.28 (P < 0.001). In HB group, this reduction was 1.20 ± 2.32 during the same period (P < 0.001). The difference of these "before-after differences" between the two groups in the GHQ-28 and all its subscales was statistically significant (P < 0.001). Also, the effects of GB physical activity on mental health compared with HB physical activity, adjusted for related baseline variables, were significant. CONCLUSIONS: These findings reveal the probable effects of GB rather than HB physical activity on mental health among the elderly.
RESUMEN
OBJECTIVES: Mental disorders such as depression, anxiety and dementia are common in elderly. However, physical activity is suggested to be effective in preventing such aging-related disorders. The aim of this study was to investigate the role of physical activity on mental health in later life. METHODS: Four hundred elderly people were randomly divided into the intervention and control groups. The intervention consisted of exercise twice a week for two months. Mental health status before, just after, and three months after the study was assessed with the 28-item General Health Questionnaire (GHQ-28). RESULTS: The mean of the GHQ-28 total scale decreased in the case group and this change remained significant after three months (before: 8 ± 5.5, after three months: 5.6 ± 4.6, p < .001). GHQ subscales including somatization, anxiety, social dysfunction, and depression decreased significantly in the case group just after and three months after the intervention. CONCLUSIONS: Physical activity significantly prevents mental disorder in older adults. Although it has effects on anxiety, social dysfunction, and depression, the greatest influence is on improving the somatization symptoms.
