Negative acculturation, the increase in high-risk profiles as immigrants live longer in the U.S., is found for a range of health behaviors and outcomes among Latino populations. Yet it has never been explored with regard to sleep duration. Using the National Health Interview Survey, we investigate Mexican immigrant and U.S.-born Mexican-American sleep durations. U.S.-born Mexican Americans are around 40% (P < 0.05) more likely to be short sleepers than Mexican immigrants after adjusting for demographic characteristics. These relationships are attenuated with the addition of health behavior variables (OR = 1.25, n.s.). This is explained because U.S.-born Mexican Americans have higher rates of smoking and stress levels, both of which are associated with increased risks of short sleeping. Because chronic partial sleep deprivation may increase health risks directly and indirectly through impaired judgment, sleep may be a mechanism through which health disparities between Mexican immigrants and U.S.-born Mexican Americans emerge.
负文化适应，即移民在美国生活时间越长，其高危特征增加，在拉丁裔人群的一系列健康行为和结果中都有体现。然而，针对睡眠时长，这种现象还从未被研究过。本研究利用全国健康访谈调查，探究了墨西哥移民和土生土长的墨西哥裔美国人的睡眠时长。调整人口特征后发现，土生土长的墨西哥裔美国人比墨西哥移民更容易成为短睡者，其可能性高出 40%（P<0.05）。加入健康行为变量后，这些关系减弱（OR=1.25，无统计学意义）。这是因为土生土长的墨西哥裔美国人吸烟和压力水平更高，这两者都与短睡风险增加有关。由于慢性部分睡眠剥夺可能通过判断力受损直接和间接增加健康风险，因此睡眠可能是导致墨西哥移民和土生土长的墨西哥裔美国人之间出现健康差异的机制之一。
