BACKGROUND
Expert opinion and cross-sectional analyses posit that obese young children will likely "outgrow" their obesity. However, given the nature of the US childhood obesity epidemic, this assertion may no longer hold true.
OBJECTIVE
To compare the weight transitions between early childhood (3-5 years) and midchildhood (7-10 years) in 2 different longitudinal cohorts: black preschool children from the inner city and from a nationally representative sample.
RESULTS
Weight transitions for children who were normal weight at baseline were not markedly different between cohorts. However, overweight and obese low-income black children had a very high probability of becoming or remaining overweight or obese by follow-up (>90% probability) in comparison with the nationally representative cohort (50%-60% probability).
CONCLUSION
Low-income black preschool children do not necessarily "outgrow" their obesity. These findings have implications for optimal timing of obesity interventions and suggest the need for an increasing focus on children during the early preschool years.
背景
专家意见和横断面分析认为，肥胖幼儿长大后可能会“摆脱”肥胖。然而，鉴于美国儿童肥胖流行的性质，这一说法可能不再成立。
目的
比较两个不同纵向队列中幼儿期（3至5岁）和童年中期（7至10岁）之间的体重变化：来自市中心的黑人学龄前儿童和全国代表性样本。
结果
基线体重正常的儿童在不同队列间的体重变化无明显差异。然而，与全国代表性队列（50%-60%的概率）相比，超重和肥胖的低收入黑人儿童在随访时变得超重或肥胖或维持超重或肥胖状态的概率非常高（>90%的概率）。
结论
低收入黑人学龄前儿童不一定会“摆脱”肥胖。这些发现对肥胖干预的最佳时机具有启示意义，并表明需要越来越关注学龄前早期的儿童。
