目标.与非拉丁裔白人相比，拉丁裔白人的社会经济状况较差，但死亡率较低。这一发现提出了一个流行病学悖论。这项研究测试鲑鱼偏见假设，拉丁美洲人从事返回移民到他们的原籍国，从而呈现“统计上不朽”和替代假设，选择更健康的移民到美国占的矛盾。国家纵向死亡率研究数据被用来检查以下群体的死亡率，鲑鱼假说是不可行的：古巴人，谁面临的障碍，对返回移民;波多黎各人，其在波多黎各的死亡记录在美国国家统计数据;和美国出生的个人，谁不受鲑鱼或健康的移民的影响。样本包括301718名非拉丁裔白人和17375名25岁或以上的拉丁裔白人。古巴人和波多黎各人的死亡率低于非拉丁裔白人。此外，美国出生的拉丁美洲人的死亡率低于美国出生的非拉丁美洲白人。无论是鲑鱼还是健康移民假说都无法解释这些发现的模式。其他因素必须发挥作用，才能降低死亡率。
Objectives. Relative to non-Latino Whites, Latinos have a worse socioeconomic profile but a lower mortality rate. a finding that presents an epidemiologic paradox. This study tested the salmon bias hypothesis that Latinos engage in return migration to their country of origin and are thereby rendered "statistically immortal" and the alternative hypothesis that selection of healthier migrants to the United States accounts for the paradox.Methods. National Longitudinal Mortality Study data were used to examine mortality rates of the following groups for whom the salmon hypothesis is not feasible: Cubans, who face barriers against return migration; Puerto Ricans, whose deaths in Puerto Rico are recorded in US national statistics; and US-born individuals, who are not subject to either salmon or healthy migrant effects.Results. The sample included 301 718 non-Latino Whites and 17 375 Latino Whites 25 years or older. Cubans and Puerto Ricans had lower mortality than non-Latino Whites. Moreover, US-born Latinos had lower mortality than US-born non-Latino Whites.Conclusions. Neither the salmon nor the healthy migrant hypothesis explains the pattern of findings. Other factors must be operating to produce the lower mortality.
