Abstract
Background: Successful aging (SA) is considered an indicator of satisfaction of older people. This study aimed to evaluate the effectiveness of the Otago Exercise Program (OEP) on SA among older women. Materials and Methods: quasi-experimental research with a control group was conducted in 2021 on 120 older women in Shiraz city, south Iran. Eligible samples were selected by a three-stage cluster sampling method and were classified into two equal intervention and control groups. Eight training sessions (exercises) were conducted for the intervention group using the OEP. SA questionnaire was completed at the beginning and 2 months after the intervention. The data were analyzed using the IBM-SPSS version 26, and the effect sizes were extracted. Results: The mean age of samples in the intervention and control groups was 69.71 + 59.59 and 68.83 + 5.08 years, respectively. Although there was no significant difference in the mean scores of SA between the two groups at the beginning of the study, 2 months after the intervention implementation, the mean scores of SA increased significantly in the intervention group (t = 8.57, p ≤ .001). Conclusion: It seems that OEP is an effective strategy for supporting SA in older people.
