This study examines the extent to which the relationship between area socioeconomic position (SEP) and low birth weight (LBW) varies by race and ethnicity. A cross-sectional, secondary data analysis was performed with 1992-1994 Vital Statistics and 1990 U.S. Census data for selected metropolitan areas. Low birth weight (< 2500 grams) rates were calculated for non-Hispanic Black, Latino, and non-Hispanic White live singleton births. Concentrated poverty was defined as poor persons living in neighborhoods with 40% or more poverty in metropolitan areas. The results showed that the relationship between concentrated poverty and LBW varied by race and ethnicity. Concentrated poverty was significant for Latinos, even when controlling for maternal health and MSA-level factors. By contrast, maternal health characteristics, such as pre-term birth, teen birth and tobacco use, explained much of the variance in African-American and White LBW These findings extend the discussion about race, class, and health disparities to include Latinos and shows how the relationship between SEP and LBW can vary within an ethnic group.
本研究考察了地区社会经济地位（SEP）与低出生体重（LBW）之间的关系因种族和族裔不同而变化的程度。利用1992 - 1994年生命统计数据以及1990年美国选定大都市区的人口普查数据进行了横断面二次数据分析。计算了非西班牙裔黑人、拉丁裔和非西班牙裔白人单胎活产的低出生体重（<2500克）率。集中贫困定义为大都市地区生活在贫困率达40%或更高社区的贫困人口。结果表明，集中贫困与低出生体重之间的关系因种族和族裔而异。即使在控制了孕产妇健康和大都市统计区层面的因素后，集中贫困对拉丁裔仍具有显著影响。相比之下，诸如早产、青少年生育和吸烟等孕产妇健康特征解释了非裔美国人和白人低出生体重差异的很大一部分。这些发现将关于种族、阶级和健康差异的讨论扩展到包括拉丁裔，并表明社会经济地位与低出生体重之间的关系在一个种族群体内部是如何变化的。
