Conclusions
Overall, this study did not observe the effects of maternal sleep
quality, sleep duration and nap duration on LBW and SGA, but found that
insufficient sleep duration during pregnancy is an independent risk
factor for PTB, and longer sleep duration may be associated with a lower
risk of PTB. It is suggested that pregnancy health care providers should
strengthen sleep problem care for pregnant women in order to reduce
adverse birth outcomes.
