背景:西班牙裔/拉丁美洲人受营养相关疾病的负担不成比例,但移民似乎比美国出生的人更健康。以西班牙裔/拉丁裔移民高度隔离为特征的社区可能会提供支持更健康饮食的环境。
目的:研究西班牙裔/拉丁裔移民隔离是否与家庭以外的食物(AFHF)消费频率和饮食质量有关,西班牙裔/拉丁裔成年人的不同样本。
方法:分析了西班牙裔社区健康研究/拉丁裔研究(HCHS/SOL)的横断面基线数据(2008-2011)。对住宅地址进行了地理编码,并与2008-2012年美国社区调查数据相关联。西班牙裔/拉丁裔移民隔离的特点是使用当地的Getis-OrdGi*统计数据,一种空间聚类度量,用于量化人口统计学上相似的邻域聚集在一起的程度。
方法:参与者是HCHS/SOL中的15,661名成年人,一项针对美国4个地区18-74岁的西班牙裔/拉丁美洲人的基于人口的研究(布朗克斯,纽约;芝加哥,伊利诺伊州;迈阿密,佛罗里达;和圣地亚哥,California).
方法:使用改良的饮食行为问卷评估AFHF消耗。使用替代健康饮食指数(AHEI)-2010(范围:0-110)评估了两次24小时召回的饮食质量。
方法:使用具有多级权重的多级线性和逻辑回归来估计西班牙裔/拉丁裔移民隔离之间的关联(低,中等,高)AHEI-2010得分,和AFHF消耗(≥3vs.<3次/周)在单独的模型中,分别。还评估了邻里贫困的中介作用以及协会是否因耶稣诞生而有所不同。
结果:较高的隔离水平与较高的调整后平均AHEI得分相关;在考虑到社区贫困后,估计值进一步放大(低隔离:参考;中等隔离:β=2.43,95%CI:1.10-3.77;高隔离:β=1.63,95%CI:0.43-2.82)。与美国出生的人相比,外国出生的人中的协会最强。隔离与AFHF消耗之间没有关联。
结论:这些结果强调了西班牙裔/拉丁裔移民社区在支持居民健康饮食方面的潜在作用,尤其是移民。
Hispanics/Latinos are disproportionately burdened by nutrition-related diseases but immigrants appear healthier than their US-born counterparts. Neighborhoods characterized by high Hispanic/Latino immigrant segregation may provide environments to support healthier diets.
To examine whether or not Hispanic/Latino immigrant segregation is associated with frequency of away-from-home food consumption and diet quality in a large, diverse sample of Hispanic/Latino adults.
Cross-sectional baseline data from the Hispanic Community Health
Study/
Study of Latinos were analyzed (2008-2011). Residential addresses were geocoded and linked to census tract-level 2008-2012 American Community Survey data. Hispanic/Latino immigrant segregation was characterized using the local Getis-Ord Gi∗ statistic, a spatial clustering measure that quantifies the extent to which demographically similar neighborhoods group together.
Participants were 15,661 adults in the Hispanic Community Health
Study/
Study of Latinos, a population-based
study of Hispanic/Latinos aged 18 to 74 years from 4 US regions (Bronx, NY; Chicago, IL; Miami, FL; and San Diego, CA).
Away-from-home food consumption was assessed using a modified dietary behavior questionnaire. Diet quality was assessed using the Alternate Healthy Eating Index 2010 (range = 0 to 110) from two 24-hour recalls.
Multilevel linear and logistic regression with multilevel weights were used to estimate associations between Hispanic/Latino immigrant segregation (low, medium, or high) with Alternate Healthy Eating Index 2010 score, and away-from-home food consumption (≥3 vs <3 times/week) in separate models, respectively. The mediating role of neighborhood poverty and whether or not associations differed by nativity were also assessed.
Higher levels of segregation were associated with higher adjusted mean Alternate Healthy Eating Index 2010 scores; estimates were further magnified after accounting for neighborhood poverty (low segregation: reference category; medium
segregation: β = 2.43, 95% CI 1.10 to 3.77; and high
segregation: β = 1.63, 95% CI .43 to 2.82). Associations were strongest among the foreign-born compared with the US-born. There was no association between
segregation and away-from-home food consumption.
These results highlight the potential role of Hispanic/Latino immigrant neighborhoods in supporting healthy diets among residents, especially immigrants.
