背景大多数涉及低出生体重风险评估的流行病学研究都集中在所有低出生体重出生。试图区分足月和早产低出生体重儿的研究倾向于检查早产低出生体重儿，因为这组婴儿围产期死亡率和发病率的风险最大。本研究使用来自北卡罗来纳州20个县的25，408例单胎分娩的数据，以识别和比较足月和早产低出生体重的风险因素，并检查可用于临床设置的足月和早产低出生体重的独立多变量风险评估系统的有用性。作为两种类型低出生体重的重要预测因素重叠的风险因素包括种族，以前没有活产，吸烟，体重低于100磅，以及以前的早产或低出生体重。年龄也是两种低出生体重的重要预测因素，但方向相反。年龄越小，足月低出生体重的风险越低，早产低出生体重的风险越高。所有危险因素的比较表明，需要不同的多变量模型来了解早产和足月低出生体重的流行病学。就临床价值而言，综合所有低出生体重儿的一般风险评估模型与单独模型一样有效。
Background. Most epidemiological research dealing with the assessment of risk for low birthweight has focused on all low birthweight births. Studies that have attempted to distinguish between term and preterm low birthweights have tended to examine preterm low birthweight, since the risk of perinatal mortality and morbidity is greatest for this group of infants.Method. This study uses data from 25,408 singleton births in a 20-county region in North Carolina to identify and compare risk factors for term and preterm low birthweights, and also examines the usefulness of separate multivariate risk assessment systems for term and preterm low birthweights that could be used in the clinical setting.Results. Risk factors that overlap as significant predictors of both types of low birthweight include race, no previous live births, smoking, weight under 100 lb, and previous preterm or low birthweight birth. Age also is a significant predictor of both types of low birthweight, but in opposite directions. Younger age is associated with reduced risk of term low birthweight and increased risk of preterm low birthweight.Conclusion. Comparison of all risk factors indicates that different multivariate models are needed to understand the epidemiology of preterm and term low birthweights. In terms of clinical value, a general risk assessment model that combines all low birthweight births is as effective as the separate models.
