摘要

兒童青少年會因為錯估體型而去減肥，過去的研究常常強調飲食障礙跟高估自己體型的相關性，但卻很少有研究強調低估體型的危險。本研究的目的是探究錯估體型跟體重相關危險因素的關係，例如低估自己體型的超重兒童的飲食障礙、活動不足等不健康的行為。我們在2006年12月1日到2007年2月15日進行了一個橫斷性、描述性的調查，共有29,313位4到12年級兒童及青少年被邀請參與這個國家型的橫斷面調查，並完成了問卷。用多元邏輯式迴歸最大可能估計分析資料，43.2%的兒童青少年錯估體型（26.4%高估；16.8%低估），超重兒童青少年低估體型的相關因素有父母肥胖、因減肥而節食、吃早餐、因減肥而催吐、吃油炸食物、進行费力的身體活動和睡眠多於八小時（危險比分別是0.86、0.42、0.88、1.37、1.13、1.11和1.17）。總之，及早建立正確體型評估可以避免不健康的行為。

Children and adolescents tend to lose weight, which may be associated with misperceptions of weight. Previous studies have emphasized establishing correlations between eating disorders and an overestimated perception of body weight, but few studies have focused on an underestimated perception of body weight. The objective of this study was to explore the relationship between misperceptions of body weight and weight-related risk factors, such as eating disorders, inactivity, and unhealthy behaviors, among overweight children who underestimated their body weight. We conducted a cross-sectional, descriptive study between December 1, 2006 and February 15, 2007. A total of 29,313 children and adolescents studying in grades 4-12 were enrolled in this nationwide, crosssectional survey, and they were asked to complete questionnaires. A multivariate logistic regression using maximum likelihood estimates was used. The prevalence of body weight misperception was 43.2% (26.4% overestimation and 16.8% underestimation). Factors associated with the underestimated perception of weight among overweight children were parental obesity, dietary control for weight loss, breakfast consumption, self-induced vomiting as a weight control strategy, fried food consumption, engaging in vigorous physical activities, and sleeping for ＞8 hours per day (odds ratios=0.86, 0.42, 0.88, 1.37, 1.13, 1.11, and 1.17, respectively). In conclusion, the early establishment of an accurate perception of body weight may mitigate unhealthy behaviors.
