Background Poor sleep is associated with adverse outcomes among postpartum women. Exercise may improve sleep, but this has not been well examined in the postpartum period. Purpose To examine the impact of a culturally modified, individually tailored lifestyle intervention on sleep outcomes among postpartum Latina women. Methods Estudio PARTO was a randomized controlled trial aimed at reducing Type 2 diabetes among Latina women with abnormal glucose tolerance in pregnancy. Participants were randomized to a lifestyle (i.e., diet and exercise; n = 70) or a health and wellness control intervention (n = 78) in late pregnancy (baseline). The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality (PSQI score), onset latency (minutes per night), duration (hours per night), efficiency (percentage of the time in bed asleep), and daytime dysfunction at baseline, 6 weeks, 6 months, and 12 months postpartum. Results Mean PSQI score (6.56 ± 3.87), sleep duration (6.84 ± 1.75 hr/night), and sleep efficiency (79.70% ± 18.10%) did not differ between the arms at baseline. Mixed-effects models indicated a greater decrease of 1.29 in PSQI score (i.e., improved sleep quality) in the lifestyle versus health and wellness arm (95% confidence interval [CI] = −2.50 to −0.08, p = .04) over follow-up. There was the suggestion of a smaller decrease in sleep duration (mean = 0.48 hr/night, 95% CI = −0.10 to 1.06, p = .10) in the lifestyle versus health and wellness arm. There were no statistically significant differences in other sleep outcomes between arms. Conclusions Findings suggest that lifestyle interventions improve sleep quality but not sleep duration, sleep onset latency, sleep efficiency, or daytime dysfunction in postpartum Latina women and, therefore, may hold promise for improving subsequent mental and physical health in this population.

生活方式干预的随机对照试验对拉丁产后妇女睡眠的影响

背景 睡眠不足与产后妇女的不良后果有关。运动可以改善睡眠，但这在产后还没有得到很好的检验。目的 研究文化改良、个性化的生活方式干预对产后拉丁裔女性睡眠结果的影响。方法 Estudio PARTO 是一项随机对照试验，旨在减少妊娠期葡萄糖耐量异常的拉丁裔妇女的 2 型糖尿病。参与者在妊娠晚期（基线）被随机分配到生活方式（即饮食和运动；n = 70）或健康和健康控制干预（n = 78）。匹兹堡睡眠质量指数（PSQI）用于测量睡眠质量（PSQI 评分）、起效潜伏期（每晚分钟数）、持续时间（每晚小时数）、效率（卧床睡眠时间百分比）、基线、产后 6 周、6 个月和 12 个月的日间功能障碍。结果 基线时两组的平均 PSQI 评分 (6.56 ± 3.87)、睡眠持续时间 (6.84 ± 1.75 小时/晚) 和睡眠效率 (79.70% ± 18.10%) 没有差异。混合效应模型表明，生活方式与健康组相比，PSQI 评分（即睡眠质量改善）下降幅度更大（95% 置信区间 [CI] = -2.50 至 -0.08，p = .04） -向上。与健康和保健组相比，生活方式组的睡眠时间减少幅度较小（平均值 = 0.48 小时/晚，95% CI = -0.10 至 1.06，p = .10）。两组之间的其他睡眠结果没有统计学上的显着差异。结论 研究结果表明，生活方式干预可以改善睡眠质量，但不能改善睡眠持续时间、入睡潜伏期、产后拉丁裔妇女的睡眠效率或日间功能障碍，因此可能有望改善该人群随后的身心健康。临床试验注册 NCT01679210。
