Objectives: This study conducted a meta-analysis of the effects of exercise intervention in improving cognitive function among institutionalized elderly people with dementia. Methods: For data analysis, PubMed, Ovid-MEDLINE, CINAHL, Cochran Library, RISS, DBpia, NDSL, KISS of studies published from 2000 to 2019 were systematically reviewed. Through this process, the average size effect of each variable was calculated and moderator variables were explored. Fourteen studies were identified and key words for searching included ‘dementia’, ‘exercise’, ‘cognitive function’. Cochrane's risk of bias for randomized studies was used to assess methodological quality. Data were analyzed using the R package version 4.0.2 program. Results: The total size effect of the exercise intervention program was average (SMD=0.52, 95% CI: 0.33~0.71, p<.0001). Statistically, moderator variable analyzed according to intervention type using meta-ANOVA showed no significant difference. Finally, no significant evidence of publication bias was found. Conclusions: The results of the study show that the exercise intervention is effective in improving cognitive function in institutionalized elderly people with dementia. Future research should examine the effects of non-pharmacological interventions targeting institutionalized elderly people with dementia in order to enhance their cognitive function.
