Greater acculturation is associated with adverse perinatal outcomes in Mexican-American women, but the mechanisms by which acculturation influences perinatal outcomes are unclear. Pregnant acculturated Mexican-American women are more likely to engage in unhealthy prenatal behaviors relative to those less acculturated, including poor sleep. As sleep disruptions are associated with acculturation and negative perinatal outcomes, particularly maternal depression, alterations in sleep may adversely affect pregnant Mexican-American women.
Sixty pregnant women of Mexican descent completed surveys about sleep, acculturation, depressive symptoms and potential protective factor of social support.
Acculturation, but not social support, significantly predicted increased sleep disruptions as well as overall feeling less refreshed upon waking across pregnancy. Moderation analysis indicated that more acculturated women who took longer to fall asleep reported increased depressive symptoms. Feeling refreshed upon waking also mediated the relationship between increased acculturation and elevated maternal depressive symptoms.
Acculturation and altered sleep contribute to greater risk in Mexican-American women for maternal depressive symptoms in the perinatal period. These findings have implications for prevention and treatment of maternal mental health disorders, which may adversely affect perinatal outcomes in the vulnerable Mexican-American population.
在美国墨西哥裔女性中，更高的文化适应程度与不良围产期结局相关，但文化适应影响围产期结局的机制尚不清楚。与文化适应程度较低的孕妇相比，文化适应程度较高的美国墨西哥裔孕妇更有可能出现不健康的产前行为，包括睡眠质量差。由于睡眠中断与文化适应及不良围产期结局相关，尤其是与产妇抑郁有关，睡眠改变可能会对美国墨西哥裔孕妇产生不利影响。
60名墨西哥裔孕妇完成了关于睡眠、文化适应、抑郁症状及社会支持潜在保护因素的调查。
文化适应程度而非社会支持显著预示着睡眠中断增加以及整个孕期醒来后总体感觉恢复不佳。调节分析表明，入睡时间较长的文化适应程度较高的女性报告的抑郁症状有所增加。醒来时感觉恢复良好也介导了文化适应程度增加与产妇抑郁症状加重之间的关系。
文化适应和睡眠改变会增加美国墨西哥裔女性在围产期出现产妇抑郁症状的风险。这些发现对预防和治疗产妇心理健康障碍具有启示意义，因为这些障碍可能会对脆弱的美国墨西哥裔人群的围产期结局产生不利影响。
