The Acceleration of Immigrant Unhealthy Assimilation
研究发现，较晚到达美国的移民群体初始肥胖率更高，且体重增长更快，即“不健康同化”速度加快，对研究移民健康变迁有参考价值。
It is well known that immigrants tend to be healthier than US natives and that this advantage erodes with time spent in the USA. However, we know less about the heterogeneity of these trajectories among arrival cohorts. Recent studies have shown that later arrival cohorts of immigrants have lower entry wages and experience less economic assimilation. In this paper, we investigate whether similar cohort effects can be observed in the weight assimilation of immigrants in the USA. Focusing on obesity, we show that more recent immigrant cohorts arrive with higher obesity rates and experience a faster 'unhealthy assimilation' in terms of weight gain.
