To explore how adolescents who try to lose weight differ from those who do not in relation to body image, food intake, knowledge about food, and sources of information about food, nutrition, and weight loss.
Data were collected from 12-15-year-old school students in North Queensland, Australia by questionnaire.
Boys who attempted weight loss reduced sweet foods and snacks, while concurrently increasing healthy foods such as fruit, yogurt, and low-fat milk. Girls who attempted weight loss ate breakfast, lunch, snacks, milk, bread, meat, and many sweet and fatty foods less often than other girls. Some reduction in meals, snacks, core foods, and sweet fatty foods, but not savory fatty foods, remained after the weight loss attempt. Boys attempting weight loss had better knowledge about high-fat and high-sugar foods than other boys, but there was no difference for girls. Girls attempting weight loss were more likely than other girls to think that core foods such as bread, potatoes, and dairy products should be reduced, whereas boys were more likely to think that sweet foods should be reduced. The majority of students who had attempted weight loss during the previous year considered themselves overweight, while few weight-conscious students were satisfied with their bodies.
The weight-conscious adolescents in this study, especially the girls, exhibited restrictive eating practices and a preoccupation with a slim image. Adolescents need a food culture based on foods to eat rather than foods to avoid, and an understanding of suitable weight-control measures.
探讨试图减肥的青少年与未试图减肥的青少年在身体形象、食物摄入、食物知识以及食物、营养和减肥信息来源方面的差异。
通过问卷调查收集了澳大利亚北昆士兰12至15岁在校学生的数据。
试图减肥的男孩减少了甜食和零食的摄入,同时增加了水果、酸奶和低脂牛奶等健康食品的摄入。试图减肥的女孩比其他女孩更少吃早餐、午餐、零食、牛奶、面包、肉类以及许多甜食和高脂肪食物。在尝试减肥后,餐食、零食、核心食物和甜腻高脂肪食物的摄入量有所减少,但咸味高脂肪食物的摄入量没有减少。试图减肥的男孩比其他男孩对高脂肪和高糖食物有更好的了解,但女孩之间没有差异。试图减肥的女孩比其他女孩更倾向于认为应该减少面包、土豆和乳制品等核心食物的摄入,而男孩则更倾向于认为应该减少甜食的摄入。前一年尝试过减肥的大多数学生认为自己超重,而很少有注重体重的学生对自己的身体感到满意。
本研究中注重体重的青少年,尤其是女孩,表现出限制性饮食行为,并痴迷于苗条的形象。青少年需要一种基于应吃食物而非应避免食物的饮食文化,以及对合适的体重控制措施的理解。
