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.
To examine the impact of a culturally modified, individually tailored lifestyle intervention on sleep outcomes among postpartum Latina women.
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.
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.
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.

睡眠质量差与产后女性的不良结局有关。运动可能有助于改善睡眠，但这在产后阶段尚未得到充分研究。
研究一种文化适应性强、个体化的生活方式干预对产后拉丁裔女性睡眠结果的影响。
PARTO 研究是一项旨在降低妊娠期间糖耐量异常的拉丁裔女性 2 型糖尿病风险的随机对照试验。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）或健康和健康对照组（n = 78）。使用匹兹堡睡眠质量指数（PSQI）来测量睡眠质量（PSQI 评分）、潜伏期（每晚分钟数）、持续时间（每晚小时数）、效率（在床上睡着的时间百分比）和产后 6 周、6 个月和 12 个月的日间功能障碍。
基线时，两组的 PSQI 评分（6.56 ± 3.87）、睡眠时间（6.84 ± 1.75 小时/晚）和睡眠效率（79.70% ± 18.10%）无差异。混合效应模型表明，与健康和健康对照组相比，生活方式组的 PSQI 评分下降 1.29（即睡眠质量改善）（95%置信区间[CI] = -2.50 至 -0.08，p =.04）。生活方式组的睡眠时间（平均 = 0.48 小时/晚，95%CI = -0.10 至 1.06，p =.10）有较小的下降趋势。两组在其他睡眠结果方面无统计学差异。
研究结果表明，生活方式干预可改善产后拉丁裔女性的睡眠质量，但不能改善睡眠持续时间、睡眠潜伏期、睡眠效率或日间功能障碍，因此可能有助于改善该人群的后续身心健康。
