Weight screening in schools has been proposed as one strategy to address childhood obesity. Students' response to such screening is unexplored, however. In this study we evaluated the perceived comfort, utility and impact of school-based weight screening from the perspective of middle school-aged students.
A cross-sectional study of 852 ethnically diverse 5th-8th grade students. Associations were investigated between measured height and weight screening data and responses to a self-administered questionnaire completed immediately following weight screening in physical education class. BMI categories were based on the revised 2000 CDC growth chart and definitions: 5th-85th BMI percentile = healthy weight, 85th-95th BMI percentile = at risk for overweight, and >95th percentile BMI = overweight.
Overall, students' comfort level with weight screening varied depending on the student's own weight status. More overweight students (38.1%) reported being uncomfortable than healthy weight students (8.1%) (p < 0.001). In particular, overweight female students (54.8%) compared to healthy weight female students (21.6%) reported being uncomfortable (p < 0.01). About half (54.9%) of all students reported knowing their weight prior to screening, and 58.9% reported that it was useful to learn their height and weight. Compared to healthy weight students, overweight students were significantly more likely to report the intention to perform weight modification related activities such as visiting a doctor (Odds ratio (OR) = 2.0, 95% CI = 1.3, 3.1), eating more fruits and vegetables (OR = 2.7, 95% CI = 1.7, 4.1), and increasing physical activity (OR = 4.3, 95% CI = 2.7, 7.0).
Overall, the majority of the middle school students did not report discomfort with school-based weight screening, did report that receiving height and weight information was useful, and generally report appropriate weight control intentions. These proportions varied across weight status categories, however, with students who were at risk for overweight or overweight reporting higher levels of discomfort. For schools that conduct weight screening, it is essential that they also provide comfortable and private settings as well as education or counseling regarding healthy weight control practices.
学校进行体重筛查已被提议作为解决儿童肥胖问题的一项策略。然而，学生对这种筛查的反应尚未得到研究。在本研究中，我们从中学生的角度评估了基于学校的体重筛查的舒适度、实用性和影响。
对852名来自不同种族的五至八年级学生进行了横断面研究。在体育课上进行体重筛查后，立即对测量的身高和体重筛查数据与一份自我管理问卷的回答之间的关联进行了调查。BMI类别基于2000年修订的美国疾病控制与预防中心（CDC）生长图表及定义：BMI百分位数在第5至85之间 = 健康体重，BMI百分位数在第85至95之间 = 超重风险，BMI百分位数大于95 = 超重。
总体而言，学生对体重筛查的舒适度因学生自身的体重状况而异。超重学生中报告感到不舒服的比例（38.1%）高于健康体重学生（8.1%）（p < 0.001）。特别是，超重女生（54.8%）报告感到不舒服的比例高于健康体重女生（21.6%）（p < 0.0１）。约一半（54.9%）的学生报告在筛查前就知道自己的体重，58.9%的学生报告了解自己的身高和体重是有用的。与健康体重学生相比，超重学生更有可能报告有进行与体重调整相关活动的意愿，如看医生（优势比（OR） = 2.0，95%置信区间 = 1.3，3.1）、多吃水果和蔬菜（OR = 2.7，95%置信区间 = 1.7，4.1）以及增加体育活动（OR = 4.3，95%置信区间 = 2.7，7.0）。
总体而言，大多数中学生并未报告对基于学校的体重筛查感到不适，确实报告收到身高和体重信息是有用的，并且普遍报告有适当的体重控制意愿。然而，这些比例在不同体重状况类别中有所不同，超重或有超重风险的学生报告的不适感更高。对于进行体重筛查的学校来说，提供舒适和私密的环境以及关于健康体重控制做法的教育或咨询至关重要。
