Shorter sleep duration is linked to obesity, coronary artery disease, and diabetes. Whether sleep deprivation during the postpartum period affects maternal postpartum weight retention remains unknown. This study examined the association of sleep at 6 months postpartum with substantial postpartum weight retention (SPPWR), defined as 5 kg or more above pregravid weight at 1 year postpartum. The authors selected 940 participants in Project Viva who enrolled during early pregnancy from 1999 to 2002. Logistic regression models estimated odds ratios of SPPWR for sleep categories, controlling for sociodemographic, prenatal, and behavioral attributes. Of the 940 women, 124 (13%) developed SPPWR. Sleep distributions were as follows: 114 (12%) women slept </=5 hours/day, 280 (30%) slept 6 hours/day, 321 (34%) slept 7 hours/day, and 225 (24%) slept >/=8 hours/day. Adjusted odds ratios of SPPWR were 3.13 (95% confidence interval (CI): 1.42, 6.94) for </=5 hours/day, 0.99 (95% CI: 0.50, 1.97) for 6 hours/day, and 0.94 (95% CI: 0.50, 1.78) for >/=8 hours/day versus 7 hours/day (p = 0.012). The adjusted odds ratio for SPPWR of 2.05 (95% CI: 1.11, 3.78) was twofold greater (p = 0.02) for a decrease in versus no change in sleep at 1 year postpartum. Sleeping </=5 hours/day at 6 months postpartum was strongly associated with retaining >/=5 kg at 1 year postpartum. Interventions to prevent postpartum obesity should consider strategies to attain optimal maternal sleep duration.

Want to Lose Weight After Pregnancy? Get Some Sleep
Posted by Shirley S. Wang
Mothers who get less than five hours of shut-eye a night have more trouble shedding pregnancy weight after childbirth than mothers who sleep for more than seven hours, according to a study published in the American Journal of Epidemiology.
The survey of 940 mothers found that the short-sleeping ones were three times as likely to keep at least 5 kilograms, or about 11 pounds, of the weight they gained during pregnancy, compared with those who got more sleep during the year after childbirth. They also tended to shed weight more slowly. The mothers were surveyed about their sleep habits at six months and one year after having the baby.
Sleep was related to weight retention even after taking into account factors such marital status, ethnicity, education, income, and number of previous children. The study also considered weight-related behaviors such as breastfeeding and being physically active.
“It looks like sleep may be as important as a health behavior, like diet and physical activity, for women in this year after pregnancy” in terms of weight retention, Erica Gunderson, lead author of the study and an investigator at the Kaiser Permanente Division of Research in Oakland, Calif., told the Health Blog. “That’s something to keep in mind, to really take care of yourself.”
Other research has found the link between sleep and weight gain in the general population.
The reasons why some moms are getting such a small amount of sleep can’t be determined from this study and will be the focus of future research, says Gunderson. When more is known about those factors, the researchers may try to design an intervention to help mothers get more sleep. No word on whether they have a plan to get newborns to sleep through the night to make things a little easier on the moms. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 请诸位战友指教！

缩减睡眠时间会出现肥胖、冠状动脉疾病及糖尿病。而对于产后睡眠缺乏是否会影响母亲产后体重恢复尚缺乏了解。
This study examined the association of sleep at 6 months postpartum with substantial postpartum weight retention (SPPWR), defined as 5 kg or more above pregravid weight at 1 year postpartum.
该项研究考查了产后6个月时的睡眠情况与实际产后体重滞留（SPPWR）（定义为产后一年体重比怀孕前重5kg或更多）间的关系。
The authors selected 940 participants in Project Viva who enrolled during early pregnancy from 1999 to 2002. Logistic regression models estimated odds ratios of SPPWR for sleep categories, controlling for sociodemographic, prenatal, and behavioral attributes.
