Descriptive analyses of birthweight for single live births in the United States during 1974, using birth certificate information, show that several factors are associated with a high incidence of low birthweight babies. Multivariate analyses were performed to determine correlates of low birthweight. When other factors are held constant, race not white, previous reproductive loss, short interpregnancy interval, out-of-wedlock birth, no prenatal care, and maternal age under 18 years or over 35 years each increase the risk of having an infant of low birthweight. High birth order and maternal education under 12 years of schooling were not consistent risk factors for low birthweight. Odds ratios are presented and the method for combining these, to estimate the risk for an individual mother having a low-birthweight infant, is illustrated.
利用出生证明信息对1974年美国单胎活产的出生体重进行的描述性分析表明,有几个因素与低体重儿的高发生率相关。进行了多变量分析以确定低体重的相关因素。当其他因素保持不变时,非白人种族、既往生殖损失、妊娠间隔短、非婚生育、未接受产前护理以及母亲年龄在18岁以下或35岁以上,均会增加生出低体重婴儿的风险。高出生顺序和母亲受教育年限在12年以下并非低体重的一致风险因素。文中给出了优势比,并说明了将这些优势比结合起来以估计个体母亲生出低体重婴儿风险的方法。
