背景——军队医院目前使用基于1948年至1961年在科罗拉多州丹佛市收集的数据得出的特定胎龄生长曲线。许多人口、环境因素以及医疗实践的变化可能使这些曲线不具代表性。
目的——确定当前使用的生长曲线是否能代表军队医院出生婴儿的标准，并制定新的曲线供军队医院使用。
方法——从军队三级和初级医疗医院的病历中收集数据。我们绘制了出生体重、身长和头围的生长曲线，并将这些23 - 42周胎龄的曲线与先前公布的标准以及1998年的国家生命统计数据进行比较。比较了各组之间的种族和民族差异。对健康足月婴儿的血糖测量进行回顾性分析，以确定潜在的安全问题。
结果——军队医院出生的婴儿生长参数显著增加。军队中的特定种族和民族群体与美国整体的这些群体相比也有所增加。按照旧标准被归类为大于胎龄儿（LGA）但根据新曲线为适于胎龄儿（AGA）的婴儿中，不到1%出现低血糖。
结论——已公布的生长曲线可能无法代表军队医院出生的婴儿。军队医院出生的足月婴儿作为一个群体以及种族和民族亚群体，比美国民用医院出生的足月婴儿体型更大。前瞻性地使用这些曲线将有助于验证它们在军队和民用托儿所的长期适用性。
Background.-Military hospitals currently use gestational age-specific growth curves based on data collected in Denver, Colo, from 1948 to 1961. A number of population and environmental factors and medical practice changes may make these curves nonrepresentative.Objective. -Determine if presently used growth curves represent norms for infants born in military hospitals and create new curves for use in military hospitals.Methods.-Data were collected from medical records of tertiary- and primary-care military hospitals. We created growth curves created for birth weight, length, and head circumference and compared these curves at gestational ages 23-42 weeks to previously published norms and to 1998 national vital statistics. Racial and ethnic differences between aroups were compared. A retrospective analysis of blood-glucose measurements for healthy term infants was performed to identify potential safety issues.Results.-Significant increases in growth parameters were noted for infants born in military hospitals. Specific racial and ethnic groups within the military also had an increase when compared with these groups in the United States as a whole. Less than I% of infants classified as large for gestational age (LGA) according by old standards but average for gestational age (AGA) according to new curves experienced hypoglycernia.Conclusion.-Published growth curves may not represent infants born in military hospitals. Term infants born in military hospitals as a group and in racial and ethnic subgroups are larger than term infants born in US civilian hospitals. Prospective use of curves will help to validate their long-term applicability in military and civilian nurseries.
