随着饮食习惯的改变，青春期很可能是肥胖症的易发时期。人们认为同伴在青少年的饮食中扮演着重要的角色，然而，有限的研究考察了同伴在这方面的作用。本研究考察了健康饮食的自我效能感、父母和同伴对健康饮食和不健康饮食的支持与食物摄入模式的关系。参与者是从爱尔兰小学后学校招募的264名男孩和219名女孩(N=483)，年龄在13-18岁之间。自我报告测量评估了自我效能、父母和同伴对健康饮食和不健康饮食的支持。饮食模式分析是营养学研究中常用的传统方法的替代方法，它是在FFQ上进行的，以得出食物的摄入模式。发现了两种模式，分别被标记为“健康食物摄入”和“不健康食物摄入”。多组模型被用来评估饮食模式相关因素的假设模型是否因性别而不同。多组模型很好地符合数据，只有一条路径显示出性别不同。较低的健康饮食自我效能感和较高的同伴对不健康饮食的支持与“不健康饮食”有关。较高的自我效能感与“健康饮食”有关。针对饮食自我效能和同伴支持不健康饮食的预防计划可能有助于改善青少年的饮食选择。(C)2012爱思唯尔有限公司。保留所有权利。
Adolescence, with its change in dietary habits, is likely to be a vulnerable period in the onset of obesity. It is considered that peers have an important role to play on adolescents' diet, however, limited research has examined the role of peers in this context. This study examined the relationship between self-efficacy for healthy eating, parent and peer support for healthy and unhealthy eating and food intake patterns. Participants were 264 boys and 219 girls (N = 483), aged 13-18 years, recruited from post-primary schools in Ireland. Self-report measures assessed self-efficacy, parent and peer support for healthy eating, and for unhealthy eating. Dietary pattern analysis, a popular alternative to traditional methods used in nutritional research, was conducted on a FFQ to derive food intake patterns. Two patterns were identified labelled 'healthy food intake' and 'unhealthy food intake'. Multi-group modelling was used to evaluate whether the hypothesized model of factors related to dietary patterns differed by gender. The multi-group model fit the data well, with only one path shown to differ by gender. Lower self-efficacy for healthy eating and higher peer support for unhealthy eating were associated with 'unhealthy food intake'. Higher self-efficacy was associated with 'healthy food intake'. Prevention programs that target self-efficacy for eating and peer support for unhealthy eating may be beneficial in improving dietary choices among adolescents. (C) 2012 Elsevier Ltd.
