The Centers for Disease Control and Prevention recommends that schools adopt 10 safeguards before launching a body mass index (BMI) screening program; however, little is known about schools' safeguard adoption. Authors identified questions from the 2014 School Health Policies and Practices Study that aligned with 4 of the 10 safeguards to estimate safeguard prevalence among schools that screened students for BMI (40.7%, = 223). Among these schools, 3.1% had all four safeguards and 56.5% had none or one. The most prevalent safeguard was having reliable and accurate equipment (54.1%, 95% confidence interval [CI] = [46.1, 62.1]). Providing staff with appropriate expertise and training was the least prevalent; respondents in 26.4% (95% CI [17.1, 35.6]) of schools received recent training on weight status assessment, weight management, and eating disorder identification. School-based BMI screening is common, but adopting multiple recommended safeguards is not. Absent these safeguards, BMI screening programs may fall short of intended outcomes and potentially incur unintended consequences.
美国疾病控制与预防中心建议学校在开展体重指数（BMI）筛查项目前采取10项保障措施；然而，对于学校采用保障措施的情况却知之甚少。作者从2014年学校健康政策与实践研究中找出了与10项保障措施中的4项相符的问题，以估算对学生进行BMI筛查的学校中保障措施的普及率（40.7%，n = 223）。在这些学校中，3.1%具备全部四项保障措施，56.5%没有或仅具备一项。最普遍的保障措施是拥有可靠且准确的设备（54.1%，95%置信区间[CI] = [46.1, 62.1]）。为工作人员提供适当的专业知识和培训最为少见；26.4%（95% CI [17.1, 35.6]）的学校的受访者近期接受了有关体重状况评估、体重管理和饮食失调识别方面的培训。以学校为基础的BMI筛查很常见，但采用多项推荐的保障措施却并非如此。若缺少这些保障措施，BMI筛查项目可能无法达到预期效果，并可能产生意想不到的后果。
