Public Square Dancing Intervention on Subjective Well-Being of Middle-Aged and Elderly People: A Meta-Analysis

Objective: To understand the influence of public square dancing on the subjective well-being of middle-aged and elderly people. Methods: According to the principle of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we search Chinese databases, such as CNKI, Wanfang Data, and VIP, and English databases, such as Proquest, Web of Science, Pubmed, Cochrane, and ScienceDirect, and collect relevant articles at home and abroad from 2006 to December 2019 for meta-analysis in January 2020. Result: A total of 10 articles were included. The meta-analysis results showed that the well-being of middle-aged and elderly people in the public square dancing intervention group was significantly higher than that of the other exercise group and control group (both P < 0.01). The results of the subgroup analysis showed the following: Different durations of intervention significantly influence the intervention effect (P 0.01). No difference was found between the effect of the mixed-gender intervention and the individual female intervention (P 0.05). No significant difference was found between the groups with weekly intervention frequency (P > 0.05). Conclusion: Public square dancing intervention is effective for middle-aged and elderly people's subjective well-being. Neither mixed intervention nor the times of weekly intervention have an impact on the intervention effect. However, the length of duration of intervention influences the intervention effect.
