目的：评估父母告知的身体质量指数（BMI）筛查对加州公立学校学生体重状况的影响。设计：一项自然实验，其中几乎所有加州学区在五年级、七年级和九年级进行年度BMI筛查，但父母告知BMI筛查结果是可选的。设置：数据来自2001年至2008年加州公立学校的强制性体能测试。参与者：共6967120名五年级、七年级和九年级的青少年（73%的入学学生）。干预措施：以学校为基础的BMI筛查与可选的家长通知。主要结果测量：在调整后的混合效应线性回归模型中，体重指数z评分是主要结果，评估是否通知父母他们的孩子的BMI在给定的一年预测BMIz score 2 years herein.Results：率的BMI筛查结果的父母通知从2001年的35%增加到2008年的52%。与没有通知相比，五年级和/或七年级的体重指数通知对随后的BMI z评分没有影响（95%置信区间，-0.03至0.01）。不同人种/种族之间的通知影响无差异。结果没有变化的敏感性analysis.Conclusions：这些研究结果表明，虽然BMI筛查本身可能有好处，父母的通知，在其目前的形式可能不会减少儿童肥胖。在确定有效的通知方法之前，学校应考虑将资源用于经证明可改善学生健康的政策和计划。
Objective: To assess the impact of body mass index (BMI) screening with parental notification on weight status for California public school students.Design: A natural experiment wherein nearly all California school districts conducted annual BMI screening in the fifth, seventh, and ninth grades, but parental notification of BMI screening results was optional.Setting: Data from mandatory fitness testing in California public schools for 2001 through 2008.Participants: A total of 6 967 120 fifth-, seventh-, and ninth-grade youth (73% of enrolled students).Intervention: School-based BMI screening with optional parent notification.Main Outcome Measure: Body mass index z score was the main outcome in adjusted mixed-effects linear regression models, assessing whether notifying parents of their child's BMI in a given year predicted BMIz score 2 years hence.Results: Rates of parental notification of BMI screening results increased from 35% in 2001 to 52% in 2008. Body mass index notification in fifth and/or seventh grade had no impact on subsequent BMI z scores ( 95% confidence interval, -0.03 to 0.01) compared with no notification. No differences in the impact of notification were seen by race/ethnicity. Results did not vary with sensitivity analyses.Conclusions: These findings suggest that while BMI screening itself could have benefits, parental notification in its current form may not reduce pediatric obesity. Until effective methods of notification are identified, schools should consider directing resources to policies and programs proven to improve student health.
