年龄较小的青少年正处于对自己的饮食越来越有控制力的年龄，同龄人成为可接受和规范饮食行为的重要社会参考。这些规范性的看法往往是不准确的，并可能导致不健康的饮食习惯的发展;虽然，规范性的误解同龄人的不健康的零食行为在青少年的个人零食行为的作用还不清楚。当前的研究是对基于社会规范的健康饮食干预措施的基线数据进行的横断面分析，该干预措施对英格兰贫困地区的两所中学进行了抽样调查。11-12岁的学生（n = 252）完成自我报告的措施，他们的人口特征和个人行为，态度，意图，和规范的看法（描述性和禁令规范），有关不健康的零食。结果表明，学生高估了同伴的日常不健康的零食消费量约3.2份，误解的同伴有更多的积极态度，不健康的零食和减少零食的消极态度。对同龄人行为和态度的误解越大，学生就越有可能食用不健康的零食，并对不健康的零食持积极态度。如果女孩对减少吃零食行为有更积极的态度，并且被误解的同龄人也有积极的态度，那么女孩减少吃零食行为的意愿更强。总括而言，11至12岁的儿童对同龄人的零食行为和态度有误解，而这种规范性的误解与学生自己的零食行为和态度有关。挑战这些误解的干预措施可能有助于减少社会对不健康零食的接受程度，并减少青少年中的不健康零食。
Younger adolescents are at an age where they have increasing control of their diet, and where peers become an important social reference for acceptable and normative dietary behaviours. These normative perceptions are often inaccurate and can lead to the development of unhealthy eating practices; although, the role of normative misperceptions of peers' unhealthy snacking behaviours in younger adolescents' personal snacking behaviours is not clear. The current study was a cross-sectional analysis of baseline data from a social norms-based healthy eating intervention sampling two secondary schools in deprived areas of England. Students aged 11-12 years (n = 252) completed self-report measures of their demographic characteristics and personal behaviours, attitudes, intentions, and normative perceptions (descriptive and injunctive norms), relating to unhealthy snacking. Results indicated students overestimated peers' daily unhealthy snacks consumption by approximately 3.2 portions, misperceived peers to have more positive attitudes towards unhealthy snacking and more negative attitudes towards reducing snacking. The greater these misperceptions of peers' behaviours and attitudes, the more likely students were to consume unhealthy snacks and have positive attitudes about unhealthy snacking. Girls had a stronger intention to reduce their snacking behaviours if they had more positive attitudes to reducing snacking behaviours and misperceived peers to also have a positive attitude. In summary, 11- to 12-year-olds misperceive the snacking behaviour and attitudes of their peers, and such normative misperceptions are associated with students' own snacking behaviours and attitudes. Interventions which challenge these misperceptions may assist in reducing the social acceptability of unhealthy snacking and in reducing unhealthy snacking amongst young adolescents.
