PurposeTo研究是否低收入妇女的低出生体重婴儿的种族差异可以部分解释在产前健康行为和心理社会factors.MethodA前瞻性调查的1,071低收入，非裔美国人和墨西哥裔妇女进行了一项前瞻性调查，在洛杉矶县，加州。在面对面的访谈中，获得了有关物质使用、产前压力、社会支持、对怀孕的态度、产前护理的开始和医疗风险的数据。医学图表数据被抽象为医学风险因素和劳动力，分娩和新生儿的数据。访谈数据与从产妇病历中检索的出生结局数据相关联。结构方程模型被用来测试一个假设的模型，在该模型中，出生体重的差异，预计将介导的种族差异，物质的使用，心理因素，和医疗risk.ResultsAs预期，非洲裔美国妇女分娩的婴儿的胎龄较早，出生体重较低，比墨西哥裔妇女。低出生体重的直接预测因素是使用药物和香烟，产前压力，对怀孕的积极态度，在一起，这些因素占观察到的种族差异出生weight.ConclusionThese数据有助于我们了解的因素，可能占种族相关的差异，低出生体重。
PurposeTo examine whether ethnic differences in low birth weight babies of low-income women may be explained in part by group differences in prenatal health behaviors and psychosocial factors.MethodA prospective survey of 1,071 low-income, primiparous African-American and Mexican-origin women was conducted in Los Angeles County, California. In face-to-face interviews, data were obtained on substance use, prenatal stress, social support, attitudes toward pregnancy, initiation of prenatal care, and medical risk. Medical chart data were abstracted regarding medical risk factors and labor, delivery, and neonatal data. Interview data were linked with birth outcome data retrieved from maternal medical records. Structural equation modeling was used to test a hypothesized model in which differences in birth weight were expected to be mediated by ethnic differences in substance use, psychosocial factors, and medical risk.ResultsAs expected, African-American women delivered babies of earlier gestational age and lower birth weight than did women of Mexican origin. Direct predictors of low birth weight were use of drugs and cigarettes, prenatal stress, and positive attitudes toward pregnancy; together, these factors accounted for the observed ethnic differences in birth weight.ConclusionThese data contribute to our understanding of the factors that may account for ethnic-associated differences in low birth weight.
