目的研究表明，移民的文化适应与许多不健康的行为有关。然而，环境因素在改变文化适应对健康行为的影响方面的作用却很少受到关注。本研究的目的是创造一个更细致入微的理解的健康影响的文化适应，通过研究邻里移民组成如何修改个人的饮食模式和aculturation.Methods横截面数据之间的关联洛杉矶县健康调查2007年成人样本的零售食品机构和美国人口普查2000年邻里特征的数据。文化适应是通过在家里说的语言和在美国的时间来衡量的。每周吃快餐一次以上以及前一天吃零份水果或蔬菜被用作不健康饮食行为的替代指标。多层次的逻辑回归模型进行了完整的样本，并在样本中只有拉丁美洲adultes.Results移民缺乏文化适应和生活在一个高比例的移民附近与健康的饮食行为。我们还发现，对于生活在移民比例较高的社区的移民来说，缺乏文化适应对经常性快餐消费的保护作用明显更强（OR：0.34，95% CI：结论在洛杉矶县的移民中，生活在其他移民密度高的社区，可以减轻文化适应对健康饮食行为的负面影响。健康饮食的推广工作应建立在这种保护作用的外展，以适应移民社区。
Objective Studies have shown that immigrants' acculturation is associated with numerous unhealthy behaviours. Yet, the role of environmental factors in modifying the effect of acculturation on health behaviours has received little attention. This study aims to create a more nuanced understanding of the health effects of acculturation by examining how neighbourhood immigrant composition modifies the association between individuals' eating patterns and acculturation.Methods Cross-sectional Data from Los Angeles County Health Survey 2007 adult sample were linked to data on retail food establishments and US Census 2000 neighbourhood characteristics. Acculturation was measured by language spoken at home and years stayed in the US. Eating fast food more than once per week and eating zero serving of fruit or vegetables during the previous day were used as proxy indicators for unhealthy dietary behaviour. Multilevel logistic regression models were performed in the full sample and in the sample with only Latino adults.Results Immigrants' lack of acculturation and living in a neighbourhood with a high percentage immigrants were associated with healthier dietary behaviour. We also identified that lack of acculturation conveyed a significantly stronger protective effect on regular fast-food consumption for immigrants living in neighbourhoods with higher percentage immigrants (OR: 0.34, 95% CI: 0.12 to 0.93).Conclusions Among immigrants in Los Angeles County, living in a neighbourhood with a high density of other immigrants attenuates the negative effects of acculturation on healthy eating behaviours. Healthy eating promotion efforts should build on this protective effect in outreach to acculturating immigrant communities.
