This paper reports the effectiveness of peer intervention in physical activity and obesity, with a focus on implementation. Peer intervention is a parallel method to traditional professional clinical processes, often targeting hard to reach populations. It includes peer education, peer counseling and peer support.
There were ten reviews on Physical Activity and seven on Obesity. Six reviews on obesity had mainly positive results; one on obesity in mental health was more negative. About two-thirds of reviews of Physical Activity interventions had positive outcomes. The overall effect was moderate. There were 39 single studies on Obesity and 46 on Physical Activity. 36% of Obesity studies and 13% of Physical Activity studies were from developing countries. Three single studies from developing countries and three from developed countries were elaborated. The extensively described implementation program was from a developed country. Discussion of limitations and strengths led to recommendations for implementation and evaluation. Overall, peer intervention in both obesity and physical activity showed quite strong evidence of effectiveness. Had all studies followed the implementation/evaluation recommendations, the strength of evidence might have been better. Future research should focus on cost-effectiveness and long-term follow-up.
本文报告了同伴干预在身体活动和肥胖方面的有效性，重点关注实施情况。同伴干预是一种与传统专业临床过程并行的方法，通常针对难以接触到的人群。它包括同伴教育、同伴咨询和同伴支持。
有十篇关于身体活动的综述和七篇关于肥胖的综述。六篇关于肥胖的综述主要得出了积极结果；一篇关于心理健康方面肥胖问题的综述则更偏向负面。约三分之二关于身体活动干预的综述有积极结果。总体效果中等。有39项关于肥胖的单项研究和46项关于身体活动的单项研究。36%的肥胖研究和13%的身体活动研究来自发展中国家。详细阐述了三项来自发展中国家的单项研究和三项来自发达国家的单项研究。广泛描述的实施计划来自一个发达国家。对局限性和优势的讨论得出了关于实施和评估的建议。总体而言，同伴干预在肥胖和身体活动方面都显示出了相当有力的有效性证据。如果所有研究都遵循实施/评估建议，证据的力度可能会更好。未来的研究应侧重于成本效益和长期随访。
