与体重相关的行为，如久坐活动、体力活动和饮食，一直是预防和减少儿童肥胖和超重发生的重点，但很少有纵向研究考察与体重相关的行为对儿童体重状态随时间变化的影响。这项研究考察了与体重相关的行为对儿童时期体重随后变化的影响。我们使用了早期儿童纵向研究幼儿园队列(ECLS-K)，这是一个具有全国代表性的美国儿童预期队列。包括人体测量在内的数据在1998-2007年间收集了6次(分析样本=4,938)。我们使用结构方程模型框架中的自回归交叉滞后模型来评估行为因素--水果、蔬菜、快餐和汽水的摄入量、看电视和体力活动--随着时间的推移对体重稳定性的影响。BMI z分数在整个童年时期高度稳定：BMI z分数对后续时期BMI z分数的标准化参数估计在0.79到0.86之间。BMI z-在幼儿园和一年级之间最不稳定，但在三到五年级之间变得非常稳定。在考虑了先前的体重后，行为因素对随后的体重几乎没有影响。最重要的行为因素是一年级和三年级看电视；每天多看一小时电视与0.04的BMI z得分相关。防止儿童早期体重过度增加很重要，因为体重模式是长期存在的；最重要的行为因素可能是限制儿童在屏幕前的时间。
Weight-related behaviors such as sedentary activity, physical activity, and diet have been the focus of efforts to prevent and reduce the occurrence of obesity and overweight in children, but few longitudinal studies have examined the effects of weight-related behaviors on changes in weight status over time in children. This study examines the effects of weight-related behaviors on subsequent changes in weight during childhood. We used the Early Childhood Longitudinal Study Kindergarten Cohort (ECLS-K), a nationally representative prospective cohort of children in the United States. Data, including anthropometric measures, were collected six times across 1998–2007 (analytic sample =4,938). We employed an autoregressive cross-lagged model in a structural equation model framework to assess the effects of behavioral factors -intake of fruit, vegetables, fast food and soda, television viewing, and physical activity - on weight stability over time. BMI z-scores were highly stable throughout childhood: the standardized parameter estimates of BMI z-scores on subsequent period BMI z-scores ranged from 0.79 to 0.86. BMI z-was least stable between Kindergarten and 1st grade but became highly stable between 3rd and 5th grades. After accounting for prior weight, behavioral factors had little effect on subsequent weight. The most important behavioral factor was TV viewing in the 1st and 3rd grades; an additional hour of daily TV viewing was associated with 0.04 higher BMI z-scores. It is important to prevent excessive weight gain early in childhood, as weight patterns are long-lasting; the most important behavioral factor may be limiting children’s screen time.
