背景资料。对“移民”或“拉丁裔健康悖论”的研究表明，尽管根据社会经济地位进行了调整，但在多种健康结果方面，拉丁裔表现出比美国出生的白人更好的健康。然而，很少有实证研究关注女性，更少关注社区居住环境如何与这些健康差异相关，特别是在饮食方面。我们分析了641名低收入妇女的基线数据，这些妇女嵌套在184个人口普查区域，参加了一项针对产后妇女的营养干预试验。个人层面的变量，包括种族/民族、出生地、在美国的时间长短、语言适应、情感和工具支持以及社会经济地位，与基于居住地址的美国人口普查数据(2000年)中的地区层面变量合并。我们通过半定量的食物频率问卷来评估每日水果和蔬菜的摄入量。使用MLW in 2.0软件，我们使用一个两级线性回归模型来确定社区移民、种族和社会经济构成与个人饮食的关系，并根据个人水平的社会人口学特征进行调整。在我们完全调整的模型中，我们观察到该地区外国出生人口每增加10个百分点，每天水果和蔬菜供应量就会显著增加1/3。地区黑人人口每增加10个百分点，个人每日水果和蔬菜摄入量就会显著减少1/5。在这群美国和外国出生的女性中，社区构成与个人饮食有关，除了个人层面的特征外，还包括照亮社区环境、移民健康和饮食。
Background. Research on the "immigrant" or "Latino health paradox" has demonstrated that Latinos exhibit better health than U.S.-born whites, for multiple health outcomes, despite adjusting for socioeconomic status. However, little empirical research has focused on women and even less has focused on how the neighborhood residential environment is associated with these health differences, particularly in the area of diet.Methods. We analyzed baseline data from 641 low-income women, nested within 184 census tracts, enrolled in a nutrition intervention trial for postpartum women. Individual-level variables, including race/ethnicity, nativity, duration of time in the United States, language acculturation, emotional and instrumental support, and socioeconomic position, were merged with tract-level variables from U.S. Census data (2000) based on residential address. We assessed daily fruit and vegetable servings through a semiquantitative food frequency questionnaire. Using MLW in 2.0 software, we employed a 2-level linear regression model to ascertain associations of neighborhood immigrant, racial, and socioeconomic composition with individual diet, adjusting for individual-level sociodemographic characteristics.Results. In our fully adjusted model, we observed a statistically significant increase of 1/3 of fruit and vegetable daily servings for each 10-percentage point increase in the tract foreignborn population. Each 10-percentage point increase in the tract Black population was associated with a significant 1/5 serving decrease in individual daily fruit and vegetable intake.Conclusions. Among this population of U.S. and foreign-born women, neighborhood composition was associated with individual diet, above and beyond individual-level characteristics, illuminating neighborhood context, immigrant health, and diet.
