Poor sleep, common during pregnancy, is associated with negative health risks. The study aimed to identify predictors of clinically significant insomnia among pregnant Latinas.
A total of 1289 pregnant Latinas recruited from obstetric clinics completed the Insomnia Severity Index (ISI) and questions about demographics and sleep.
Clinically significant insomnia (ISI≥10) was present among 17% of participants. Significant correlates of clinically significant insomnia were higher scores on the Edinburgh Postnatal Depression Scale (EPDS) after removing the sleep item (47% of women with EPDS≥9 and 9% with EPDS<9), completing measures in English (rather than Spanish: 26% versus 13%), and income but not pregnancy week, age, highest education level, or marital status. The highest percentage of clinically significant insomnia (59%) was experienced by women with EPDS≥9 who completed measures in English. The lowest percentage of clinically significant insomnia (6.2%) was experienced by women with EPDS<9 who completed measures in Spanish.
In this sample of low-income, mostly Spanish-speaking pregnant Latinas, rates of clinically significant insomnia appear to be higher than rates among nonpregnant Latinas. Rates of clinically significant insomnia are particularly high among Latinas with elevated depressive symptom severity, a known risk for insomnia. Acculturation, as indicated by completing measures in English, may be another risk specific to Latinas, possibly owing to loss of some ethnicity-specific protective factors (e.g., social support, strong family ties, and group identity). It will be important to directly test this explanation in future research.
怀孕期间普遍存在睡眠质量差的问题，这与负面健康风险有关。本研究旨在确定拉丁裔孕妇中临床显著失眠的预测因素。
共有 1289 名从产科诊所招募的怀孕拉丁裔妇女完成了失眠严重程度指数（ISI）和关于人口统计学和睡眠的问题。
17%的参与者存在临床显著失眠（ISI≥10）。与临床显著失眠相关的显著因素包括：去除睡眠项目后爱丁堡产后抑郁量表（EPDS）评分较高（47%的 EPDS≥9 分，9%的 EPDS<9 分）、用英语（而不是西班牙语）完成测量（26%比 13%）以及收入，而不是怀孕周数、年龄、最高教育水平或婚姻状况。EPDS≥9 分且用英语完成测量的女性经历的临床显著失眠比例最高（59%）。EPDS<9 分且用西班牙语完成测量的女性经历的临床显著失眠比例最低（6.2%）。
在这个低收入、主要讲西班牙语的怀孕拉丁裔妇女样本中，临床显著失眠的发生率似乎高于非怀孕拉丁裔妇女。在抑郁症状严重程度升高的拉丁裔妇女中，临床显著失眠的发生率尤其高，这是失眠的一个已知风险。适应文化，如用英语完成测量，可能是拉丁裔特有的另一个风险，这可能是由于失去了一些特定的族裔保护因素（例如社会支持、牢固的家庭关系和群体认同）。在未来的研究中，直接检验这一解释将是很重要的。
