To investigate associations of self-perceived eating-related peer norms (called 'subjective peer norms') with adolescents' healthy eating intentions and intake of healthy and unhealthy food.
Cross-sectional data were collected in a large international survey.
Two types of subjective peer norms were assessed: perceived peer encouragement of healthy eating and perceived peer discouragement of unhealthy eating. Outcome variables were healthy eating intentions, intake of healthy food (fruits and vegetables) and intake of unhealthy food (snacks and soft drinks).
Over 2500 European (pre-)adolescents aged between 10 and 17 years participated.
Subjective peer norms were associated with all three outcome variables. While both perceived encouragement of healthy eating and perceived discouragement of unhealthy eating were related to intentions, only peer encouragement of healthy eating was related to intakes of both healthy and unhealthy food.
Subjective peer norms play a role in adolescent eating behaviour and as such are an important target for health promotion. Addressing norms that encourage healthy eating may be more promising in changing behaviour than norms that discourage unhealthy eating.
探讨自我认知的与饮食相关的同伴规范（称为“主观同伴规范”）与青少年健康饮食意图以及健康和不健康食品摄入量之间的关联。
在一项大型国际调查中收集横断面数据。
评估了两种类型的主观同伴规范：同伴对健康饮食的鼓励认知和同伴对不健康饮食的劝阻认知。结果变量为健康饮食意图、健康食品（水果和蔬菜）摄入量以及不健康食品（零食和软饮料）摄入量。
2500多名年龄在10至17岁之间的欧洲（准）青少年参与了研究。
主观同伴规范与所有三个结果变量相关。虽然同伴对健康饮食的鼓励认知和对不健康饮食的劝阻认知均与意图相关，但只有同伴对健康饮食的鼓励认知与健康和不健康食品的摄入量相关。
主观同伴规范在青少年饮食行为中起作用，因此是健康促进的重要目标。与劝阻不健康饮食的规范相比，针对鼓励健康饮食的规范进行干预可能在改变行为方面更有前景。
