尽管墨西哥移民的教育水平较低,获得医疗保健服务的机会有限,但他们的健康状况比美国移民好。天生的个体。研究表明,墨西哥的健康优势可能部分归因于健康状况较差的移民中的选择性回归移民-通常被称为“鲑鱼偏见”。我们的研究利用了一个难得的机会来观察墨西哥裔男性在穿越墨西哥边境时的健康状况。为了评估不健康的移民是否在返回的人中不成比例,我们使用了两项加利福尼亚州研究的数据:加州健康访谈调查;和移民研究,一项对通过蒂华纳进入和离开美国的墨西哥移民进行抽样调查。我们汇集这些数据来源,以寻找与健康有关的返回移民的证据。结果提供了混合支持鲑鱼偏见。虽然报告健康限制和频繁压力的移民更有可能返回,但我们发现几乎没有证据表明慢性病和自我报告的健康状况与更高的返回概率有关。结果还提供了一些迹象表明,有限的医疗保健机会增加了最不健康的人返回的可能性。本研究提供了新的理论思考,并进一步阐明了健康和迁移决策之间的关系。
Despite having lower levels of education and limited access to health care services, Mexican immigrants report better health outcomes than U.S.-born individuals. Research suggests that the Mexican health advantage may be partially attributable to selective return migration among less healthy migrants—often referred to as “salmon bias.” Our study takes advantage of a rare opportunity to observe the health status of Mexican-origin males as they cross the Mexican border. To assess whether unhealthy migrants are disproportionately represented among those who return, we use data from two California-based studies: the California Health Interview Survey; and the Migrante Study, a survey that samples Mexican migrants entering and leaving the United States through Tijuana. We pool these data sources to look for evidence of health-related return migration. Results provide mixed support for salmon bias. Although migrants who report health limitations and frequent stress are more likely to return, we find little evidence that chronic conditions and self-reported health are associated with higher probabilities of return. Results also provide some indication that limited health care access increases the likelihood of return among the least healthy. This study provides new theoretical considerations of return migration and further elucidates the relationship between health and migration decisions.
