This systematic review investigates evidence on the association between body image concerns and weight-related behaviours of adolescents and emerging adults. It includes peer-reviewed journal articles reporting research involving body image concerns and weight-related behaviours of adolescents and emerging adults, published between 2005–2017, and located through systematic searches from four databases. This review includes studies from 11 countries or regions: United States (n = 13), Asia (n = 9), Europe (n = 8), Middle East (n = 3), South America (Brazil; n = 3), Canada (n = 3), Australia (n = 1), New Zealand (n = 1), Trinidad (n = 1), Turkey (n = 1) and Seychelles (n = 1); 24 different countries (n = 1); three Asian countries and the United States (n = 1). Out of 46 studies included in this review, 45 studies reported a positive association between body image concerns and weight-related behaviours. Adolescents and emerging adults who misperceived their weight engaged in weight-related behaviours. Higher body dissatisfaction had a significant association in the development of eating disorders and extreme weight-loss behaviours. Body image concerns play a significant role in adolescents and emerging adults engaging in weight-related behaviours. Experimental research designs are required to determine the causality of this association. Evidence strongly suggests policy makers and public health practitioners contemplate strategies to promote positive body image and healthy weight-related behaviours among adolescents and emerging adults.

青少年和新兴成年人的身体形象问题与体重相关行为之间的关系：系统评价

本系统评价调查了关于身体形象问题与青少年和新兴成年人体重相关行为之间关联的证据。它包括同行评议的期刊文章，报告涉及青少年和新兴成年人的身体形象问题和体重相关行为的研究，发表于 2005 年至 2017 年间，并通过来自四个数据库的系统搜索找到。本综述包括来自 11 个国家或地区的研究：美国（n= 13), 亚洲 (n= 9), 欧洲 (n= 8), 中东 (n= 3)、南美洲（巴西；n= 3), 加拿大 (n= 3), 澳大利亚 (n= 1), 新西兰 (n= 1), 特立尼达 (n= 1), 土耳其 (n= 1) 和塞舌尔 (n= 1); 24个不同的国家（n= 1); 三个亚洲国家和美国（n= 1)。在本次审查的 46 项研究中，45 项研究报告了身体形象问题与体重相关行为之间的正相关关系。误解自己体重的青少年和新兴成年人从事与体重相关的行为。较高的身体不满意与饮食失调和极端减肥行为的发展有显着关联。身体形象问题在从事与体重相关的行为的青少年和新兴成年人中发挥着重要作用。需要实验研究设计来确定这种关联的因果关系。证据强烈表明政策制定者和公共卫生从业者考虑采取策略，在青少年和新兴成年人中促进积极的身体形象和健康的体重相关行为。
