Background: Peer support has been suggested as a promising approach for diabetes management. No conclusive evidence exists on the effects of peer support on self-efficacy and quality of life in adults with type 2 diabetes.
Objective: To assess the effectiveness of peer support on self-efficacy and the quality of life in adults with type 2 diabetes.
Design: A systematic review and meta-analysis of randomized controlled studies.
Data sources: We searched PubMed, Embase, Cochrane Central Register of Controlled Trials and Allied Health Literature database guide for relevant literatures from inception to 30 September 2017.
Review methods: The review was conducted according to the guidelines of Cochrane Collaboration. The outcomes were self-efficacy and quality of life. The standardized mean difference and 95% confidence intervals were calculated for pooled results.
Results: A total of 15 studies met the inclusion criteria. The pooled results revealed that peer support did not significantly improve self-efficacy and quality of life in adults with type 2 diabetes, but significantly improved self-efficacy and quality of life in studies with intervention duration ≤6 months. There was no evidence of publication bias.
Conclusion: Peer support intervention did not lead to better effects on the improvement in self-efficacy and quality of life among adults with type 2 diabetes. However, peer support with intervention duration not more than 6 months had positive effects on self-efficacy and quality of life. More high-quality studies with large sample size are needed to support or counter the results.
背景: 有人建议将同伴支持作为一种有希望的糖尿病管理方法。但是,并不存在确凿证据足以证明同伴支持在2型糖尿病成年患者自我效能和生活质量方面的效果。 目的: 评估同伴支持在2型糖尿病成年患者自我效能和生活质量方面的有效性。 设计: 随机对照研究的系统性评价和荟萃分析。 数据来源: 我们搜索了PubMed、Embase、Cochrane Central Register of Controlled 从开始至2017年9月30日的相关文献的试验和联合健康文献数据库指南 综述方法: 该评价按照科克伦协作组织指南进行。结果是自我效能和生活质量。并且,为汇集结果,计算标准平均差和95%置信区间。 结果: 总共有15项研究满足纳入标准。汇集结果表明,同伴支持并不会显著提高2型糖尿病成年患者的自我效能和生活质量,但是,却在干预持续时间不超过6个月的研究方面显著提高了自我效能和生活质量。没有证据显示存在发表性偏倚情况。 结论: 同伴支持干预并不会给2型糖尿病成年患者自我效能和生活质量的提升带来更好的效果。然而,在干预持续时间不超过6个月的情况下,同伴支持对自我效能和生活质量有着积极的效果。我们需要具有大样本量的更多高质量研究来支持或反驳该结果。.
