目的：预防儿童肥胖非常重要。然而，改变儿童的生活方式以减少超重是一个巨大的挑战。准确地认识到自己超重/肥胖与改变生活方式行为的更大动机有关。如果儿童和青少年暴露在他们周围的超重/肥胖人群中，他们可能不太可能认为自己超重/肥胖。设计：魁北克省儿童与青少年健康与社会调查是一项在1999年1月至5月期间对儿童和青少年进行的具有省级代表性的以学校为基础的调查。研究对象：178所学校的3665名儿童和青少年(9岁，1267岁；13岁，1186岁；16岁，1212岁)。平均体重指数(BMI)分别为17.5、20.6和22.2 kg/m(2)。测量：根据对体重状况的自我知觉(Stunkard Body Rating Scale)与实际BMI(根据测量的身高和体重)之间的标准化差计算误解分数。结果：超重和肥胖的青少年比非超重的青少年更容易误解自己的体重(P<；0.001)。多水平模型显示，父母和同学BMI越大，儿童和青少年对体重状况的误解(低估)越大。结论：生活在父母和同学超重/肥胖等日常生活环境中的儿童和青少年，可能会对什么是适当的体重状况产生不准确的认知。针对误解可以促进健康生活方式的养成，提高肥胖预防干预的有效性。
Objective: Obesity prevention in childhood is important. However, changing children's lifestyle behaviors to reduce overweight is a substantial challenge. Accurately perceiving oneself as overweight/obese has been linked to greater motivation to change lifestyle behaviors. Children and adolescents may be less likely to perceive themselves as overweight/obese if they are exposed to overweight/obese people in their immediate environments. This study examined whether youth who are exposed to overweight parents and schoolmates were more likely to misperceive their own weight status.Design: The Quebec Child and Adolescent Health and Social Survey was a provincially representative, school-based survey of children and adolescents conducted between January and May 1999.Subjects: 3665 children and adolescents ( age 9, n = 1267; age 13, n 1186; age 16, n 1212) from 178 schools. Mean body mass index (BMI) was 17.5, 20.6 and 22.2 kg/m(2), respectively.Measurements: The misperception score was calculated as the standardized difference between self-perception of weight status (Stunkard Body Rating Scale) and actual BMI ( from measured height and weight). Exposure to obesity was based on parent and schoolmate BMI.Results: Overweight and obese youth were significantly more likely to misperceive their weight compared with non-overweight youth (P < 0.001). Multilevel modeling indicated that greater parent and schoolmate BMI were significantly associated with greater misperception ( underestimation) of weight status among children and adolescents.Conclusion: Children and adolescents who live in environments in which people they see on a daily basis, such as parents and schoolmates, are overweight/obese may develop inaccurate perceptions of what constitutes appropriate weight status. Targeting misperception may facilitate the adoption of healthy lifestyle behaviors and improve the effectiveness of obesity prevention interventions.
