目的：为了评估拉丁裔种族、拉丁裔亚群和低出生体重（LBW）之间的关系。数据来源：从MEDLINE计算机数据库，我们使用关键词出生体重;婴儿，LBW;拉丁裔;西班牙裔美国人;古巴裔美国人;墨西哥裔美国人;和波多黎各人来识别分析拉丁裔LBW的研究。研究选择：选择了1982年至1996年发表的32项研究，这些研究分析了美国拉丁美洲人和白人或多个拉丁美洲人亚组，使用了LBW的修订定义（10 000）。两名评论员提取了低出生体重率和医学研究所风险因素与低出生体重之间的关系的数据，按母亲种族和拉丁美洲亚组。拉丁裔（中位数，6.2%）和白色婴儿（中位数，5.8%）的低出生体重率相似。按拉丁裔亚组，中/南美、古巴、墨西哥和白色婴儿的LBW发生率相似。波多黎各婴儿的低出生体重率一直较高（中位数为9.1%）。两个危险因素-产妇出生地和妊娠期体重增加-被确定为混杂因素之间的关系，拉丁裔种族，拉丁裔亚组，和LBW.Conclusions：低出生体重率的拉丁裔和白人是相似的，符合“流行病学悖论”意想不到的有利围产期结果为拉丁裔。然而，所有拉丁美洲人的这种矛盾关系掩盖了波多黎各人中明显升高的LBW风险。需要进一步研究拉丁美洲人中的LBW，包括文化因素。
Objective: To assess the relation between Latino ethnicity, Latino subgroup, and low birth weight (LBW).Data Sources: From the MEDLINE computer database, we used the key words birth weight; infant, LBW; Latinos; Hispanic Americans; Cuban Americans; Mexican Americans; and Puerto Ricans to identify studies that analyzed LBW in Latinos.Study Selection: Thirty-two studies, published from 1982 to 1996, that analyzed US Latinos and whites or multiple Latino subgroups, that used the revised definition of LBW (10 000) were selected.Data Extraction: Two reviewers extracted LBW rates and data on the relation between Institute of Medicine risk factors and LBW by maternal ethnicity and Latino subgroup.Data Synthesis: Low-birth-weight rates were similar for Latino (median, 6.2%) and white infants (median, 5.8%). By Latino subgroup, LBW rates were similar for Central/South American, Cuban, Mexican, and white infants. Puerto Rican infants had consistently higher LBW rates (median, 9.1%). Two risk factors-maternal birthplace and gestational weight gain-were identified as confounders of the relation between Latino ethnicity, Latino subgroup, and LBW.Conclusions: Low-birth-weight rates of Latinos and whites are similar, consistent with the ''epidemiologic paradox'' of unexpectedly favorable perinatal outcomes for Latinos. However, this paradoxical relation for all Latinos masks the notably elevated LBW risk among Puerto Ricans. Further study of LBW among Latinos, including cultural factors, is needed.
