To systematically analyze growth data from infant health maintenance records to characterize infant weight gain increasing risk for childhood overweight, and to identify additional information from those records that could refine risky infant weight gain as a screening tool.
Retrospective cohort study.
A pediatric office in central Pennsylvania.
Children aged 6 to 8 years (n = 129) born in 2000 or later who attended health maintenance visits.
Risky infant weight gain was a cutoff selected after considering its sensitivity and specificity during the interval best predicting childhood overweight risk as determined with receiver operating characteristic curve analysis. We identified demographic, growth pattern, and parental feeding choice differences between at-risk infants who did and did not become overweight children.
Childhood overweight, defined as a sex- and age-specific body mass index of the 85th percentile or higher at ages 6 to 8 years according to 2000 Centers for Disease Control and Prevention growth charts.
Childhood overweight prevalence was 24.8%. At-risk infants gained at least 8.15 kg from ages 0 to 24 months. While 31.4% of at-risk infants became overweight children, 68.6% were resilient. At-risk, resilient participants had parents with more education, had lower weight gain from ages 18 to 24 months and 0 to 24 months and a smaller area under the weight-gain curve from ages 0 to 24 months, were more often exclusively breastfed for 6 months or longer, and were introduced to solid foods later than at-risk, overweight participants.
While most researchers would not recognize weight gain of 8.15 kg or more from ages 0 to 24 months as rapid growth, it was a fair screening tool for childhood overweight in our sample and had the potential to be refined using information about demographic characteristics, growth patterns, and parental feeding choices.
系统分析婴儿健康维护记录中的生长数据，以描述婴儿体重增加情况，确定儿童期超重风险增加的因素，并从这些记录中识别其他信息，以完善将有风险的婴儿体重增加作为一种筛查工具。
回顾性队列研究。
宾夕法尼亚州中部的一家儿科诊所。
2000年或之后出生、参加健康维护检查的6至8岁儿童（n = 129）。
有风险的婴儿体重增加是在通过接受者操作特征曲线分析确定的最能预测儿童期超重风险区间内，考虑其敏感性和特异性后选定的一个临界值。我们确定了超重和未超重的有风险婴儿在人口统计学、生长模式和父母喂养选择方面的差异。
儿童期超重，根据2000年疾病控制与预防中心生长图表，定义为6至8岁时按性别和年龄划分的体重指数处于第85百分位或更高。
儿童期超重患病率为24.8%。有风险的婴儿在0至24个月期间体重至少增加8.15千克。虽然31.4%的有风险婴儿成为超重儿童，但68.6%具有弹性。有风险且具有弹性的参与者的父母受教育程度更高，在18至24个月以及0至24个月期间体重增加较少，0至24个月期间体重增加曲线下面积较小，更常进行6个月或更长时间的纯母乳喂养，并且比有风险的超重参与者更晚开始添加固体食物。
虽然大多数研究人员不会将0至24个月期间体重增加8.15千克或更多视为快速生长，但在我们的样本中，这是一个合理的儿童期超重筛查工具，并且有可能利用人口统计学特征、生长模式和父母喂养选择方面的信息进行完善。
