Research exploring the relationship between weight perception and depressed mood among adolescents is limited in the United States. The purpose of this study is to examine the association of perceived versus actual body weight and depressed mood in a representative sample of 8th and 11th grade public school students in Texas. Using data from the 2004-2005 School Physical Activity and Nutrition (SPAN) study, logistic regression analyses were conducted to assess the association of weight perception with depressed mood. Healthy weight students who perceived themselves to be a healthy weight were the reference group for all analyses. A high prevalence of misperception of body weight was observed. Overweight and obese 8th grade girls and boys who perceived themselves to be overweight had increased odds of depressed mood [Girls: OR 1.70 (95% CI: 1.07-2.69), Boys: OR 2.05 (95% CI: 1.16-3.62)]. Healthy weight 8th grade girls who perceived themselves to be overweight had 2.5 times greater odds of depressed mood (OR 2.63, 95% CI: 1.54-4.50). Healthy weight boys who perceived themselves to be underweight had more than twice the odds (OR 2.18, 95% CI: 1.23-3.89) of depressed mood. No weight category was significantly associated with depressed mood in boys or girls in 11th grade. The present study suggests that weight misperceptions are associated with depressed mood in young adolescents. Education about healthy body size is necessary to correct the common weight misperceptions observed. The high prevalence rates of depressed mood suggest a greater need for research into understanding factors that may contribute to depressed mood in adolescents.
美国在研究青少年体重认知与抑郁情绪之间的关系方面所做的工作十分有限。本研究旨在通过对德克萨斯州公立中学 8 年级和 11 年级学生的代表性样本进行调查，以检验感知体重与实际体重以及抑郁情绪之间的关系。本研究使用了 2004-2005 学年学校体育活动与营养调查（SPAN）的数据，采用逻辑回归分析法评估了体重认知与抑郁情绪之间的关系。将健康体重且自我认知健康的学生作为所有分析的参照组。研究结果显示，存在大量的体重认知偏差现象。超重和肥胖的 8 年级女生和男生如果认为自己超重，那么他们患抑郁情绪的风险会增加[女生：比值比（OR）为 1.70（95%可信区间：1.07-2.69），男生：OR 为 2.05（95%可信区间：1.16-3.62）]。认为自己超重的健康体重 8 年级女生患抑郁情绪的风险增加了 2.5 倍（OR 为 2.63，95%可信区间：1.54-4.50）。认为自己体重过轻的健康体重男生患抑郁情绪的风险增加了两倍以上（OR 为 2.18，95%可信区间：1.23-3.89）。在 11 年级，没有任何体重类别与男孩或女孩的抑郁情绪显著相关。本研究表明，体重认知偏差与青少年的抑郁情绪有关。有必要对青少年进行有关健康体型的教育，以纠正常见的体重认知偏差。高比例的抑郁情绪表明，需要进一步研究理解可能导致青少年抑郁情绪的因素。
