Data from the 1990 North Carolina Youth Risk Behavior Survey (YRBS) were used to examine adolescents' perceptions of relative weight and the relationship of these perceptions to physical activity levels, efforts to lose weight, and time spent viewing television. A total of 3,437 ninth and 12th grade respondents to the May 1990 survey were included in the analysis. Of this sample, 25% perceived themselves as "too fat." Of that group, 68% were trying to lose weight. Females made up 75% of those reporting they were "too fat" and were trying to lose weight. White females were more likely to think of themselves as overweight and were more likely to be trying to lose weight than black females. Adolescents who perceived themselves as "too fat" reported fewer days of strenuous activity, fewer hours of strenuous exercise in physical education classes, and more hours spent viewing television on school days.
1990年北卡罗来纳州青少年风险行为调查（YRBS）的数据用于研究青少年对自身相对体重的认知，以及这些认知与身体活动水平、减肥努力和看电视时间之间的关系。1990年5月调查的3437名九年级和十二年级受访者被纳入分析。在这个样本中，25%的人认为自己“太胖”。在那一组中，68%的人试图减肥。报告自己“太胖”并试图减肥的人中有75%是女性。白人女性比黑人女性更有可能认为自己超重，也更有可能试图减肥。认为自己“太胖”的青少年报告说，剧烈活动的天数较少，体育课上剧烈运动的时间较少，上学日看电视的时间较多。
