目的评估反复或慢性应激源暴露的累积影响是否有助于在美国随时间推移的移民经常观察到的不健康同化效应。方法我们分析了1988-1994年间国家健康和营养检查调查的数据，估计了墨西哥移民中具有高稳态负荷得分的多变量Logistic回归模型，根据在美国居住的年限对墨西哥移民进行分层，并控制人口、社会经济和健康投入变量。结果估计表明，45-60岁的墨西哥移民抵达美国时的稳态负荷得分低于出生于美国的墨西哥裔美国人，非西班牙裔白人和非西班牙裔黑人的健康优势随着在美国居住的时间的延长而减弱。结论我们的分析结果与对应激源的重复或慢性生理适应是对墨西哥移民观察到的“不健康同化”效应的一个因素的假设是一致的。
ObjectiveTo assess whether the cumulative impact of exposure to repeated or chronic stressors, as measured by allostatic load, contributes to the "unhealthy assimilation" effects often observed for immigrants with time in the United States.MethodsWe analyzed data from the National Health and Nutrition Examination Survey, 1988-1994, to estimate multivariate logistic regression models of the odds of having a high allostatic load score among Mexican immigrants, stratified by adult age group, according to length of residence in United States, controlling for demographic, socioeconomic, and health input covariates.ResultsEstimates indicate that 45-60-year-old Mexican immigrants have lower allostatic load scores upon arrival than U.S.-born Mexican Americans, non-Hispanic whites, and non-Hispanic blacks, and that this health advantage is attenuated with duration of residence in the United States.ConclusionsThe findings of our analysis are consistent with the hypothesis that repeated or chronic physiological adaptation to stressors is one contributor to the "unhealthy assimilation" effect observed for Mexican immigrants.
