肥胖症是一个主要的公共卫生问题，也是整个生命周期中重大负担的原因。从幼儿期开始的纵向样本为研究肥胖提供了一种有利的方法，因为它有可能观察到个体内随时间的变化。然而，在许多现有的儿童纵向研究中，特别是那些研究心理障碍的研究，并没有评估超重/肥胖状态或计算BMI所需的相关结构。我们提供了一种独特的薄片方法，用于使用先前收集的视频数据评估肥胖/超重状态。目前的研究观察编码超重/肥胖状态的临床富集样本的学龄前儿童过度抽样抑郁症（N= 299）。学龄前儿童（3-6岁）与实验者一起完成1-8个结构化观察任务。超重/肥胖使用“薄片”技术编码，具有7820个可用于分析的独特评级。在整个研究过程中评估了父母报告的身体健康问题，并提供了8-19岁的BMI量表。在3-6岁学龄前儿童中可靠地观察到超重/肥胖的薄片评级。学龄前儿童超重/肥胖的薄片评分在8-19岁的6个独立评估中显着预测青少年BMI的下降。此外，随着时间的推移，学前班超重/肥胖薄片评级与更多的身体健康问题以及学前班期间较少的运动/活动参与有关。超重/肥胖可以在学龄前儿童中观察到，并提供了未来BMI百分位数的可靠估计。研究结果强调了如何利用先前收集的数据来研究超重/肥胖的发展轨迹，以告知这一关键的公共卫生问题。
Obesity is a major public health problem and cause of significant burden across the lifespan. Longitudinal samples, beginning in early childhood offer an advantageous approach to studying obesity, given the potential to observe within-individual changes over time. Yet among the many available longitudinal studies of children, particularly those studying psychological disorders, do not assess for overweight/obesity status or related constructs necessary to compute BMI. We offer a unique thin slice approach for assessing obesity/overweight status using previously collected video data. The current study observationally coded overweight/obesity status in a clinically enriched sample of preschoolers oversampled for depression (N= 299). Preschoolers (ages 3–6 years) completed 1–8 structured observational tasks with an experimenter. Overweight/obesity was coded using a “thin slice” technique with 7820 unique ratings available for analysis. Parent-reported physical health problems were assessed throughout the study and BMI percentiles were available from ages 8–19 years. Thin-slice ratings of overweight/obesity were reliably observed in preschoolers’ ages 3–6 years. Thin-slice ratings of overweight/obesity during preschool significantly predicted adolescent BMI percentiles at six separate assessments spanning ages 8–19 years. Further, preschool overweight/obese thin-slice ratings were associated with more physical health problems over time and less sport/activity participation during preschool. Overweight/obesity can be observationally identified in preschool-age children and offers a reliable estimate of future BMI percentile. Study findings highlight how previously collected data could be utilized to study the developmental trajectories of overweight/obesity to inform this critical public health problem.
