Linkage of measures of the adequacy, content, and quality of prenatal care with pregnancy outcome is a long-standing research challenge. We attempted to improve on prior studies by developing a measure of prenatal care that encompasses the specific items thought to mediate its relationship with birthweight and by then examining the association of this measure with birthweight. An eight-item index of prenatal care was used to abstract information from the medical records of 63 white and 56 black women who gave birth to low-birthweight (less than 2500 g) infants and 61 white and 101 black women who gave birth to normal-weight (3000 + g) infants in 1987 at two Kaiser Permanente facilities. In univariate analyses the mean values for the index were higher in controls than in cases for both black and white women, but the difference was statistically significant only for blacks. In multivariate analysis the index was not significantly associated with the risk of low birthweight for whites or blacks. Prenatal care was extremely homogeneous in this population, which compromised the evaluation of the index as a correlate of low birthweight. We believe that this is a promising method for assessing the content of prenatal care and studying the association between content and outcome of care.
产前护理的充分性、内容和质量指标与妊娠结局的关联是一个长期存在的研究难题。我们试图改进先前的研究，开发一种产前护理指标，该指标涵盖了被认为可调节其与出生体重关系的具体项目，然后研究该指标与出生体重之间的关联。使用一个包含八项的产前护理指数，从1987年在两家凯撒医疗机构分娩的63名白人妇女和56名黑人妇女（她们产下低体重（小于2500克）婴儿）以及61名白人妇女和101名黑人妇女（她们产下正常体重（3000克及以上）婴儿）的病历中提取信息。在单变量分析中，该指数的平均值在对照组中高于病例组，无论是黑人妇女还是白人妇女，但差异仅在黑人中具有统计学意义。在多变量分析中，该指数与白人或黑人低出生体重风险无显著关联。该人群中的产前护理极其同质化，这不利于将该指数作为低出生体重的相关因素进行评估。我们认为这是一种评估产前护理内容以及研究护理内容与护理结局之间关联的有前景的方法。
