Methods Two institutions of maternal and child health care were selected from urban,suburban,and exurban areas respectively from December 15th,2015 to January 15th,2016 by using the cluster sampling method.The survey was conducted among 1 152 parents with infants aged 1~3 months,and the general information,parenting and family environment,sleep environment,sleep problems were collected by self-designed questionnaire.Chi-squared test and multivariate Logistic regression analysis were used to explore associated factors. Results Of the 1 152 infants,the percentage of sleeping with adults was 73.8%,the percentages of shaking or patting to sleep and sleeping with a nipple were 72.9 % and 59.8 % respectively,and keeping a nightlight on was 52.0%.The rates of difficulty in falling asleep and circadian rhythm disorder were 50.3% and 60.4% respectively.The rates of mouth breathing,snoring and apnea in sleep breathing disorders were 33.0%,26.5% and 3.5% respectively.Significant predictors of increased odds of difficulty in falling asleep included the children older age (days)(OR=1.013,95%CI:1.002~1.023),caesarean birth(OR=1.509,95%CI:1.101~2.068),mixed feeding(OR=1.401,95%CI:1.036~1.894),improper sleep environment(OR=1.602,2.587,2.278,95%CI:1.177~2.180,1.113~6.011,1.217~4.263),lack of pre-sleep ritual (OR=1.611,95%CI:1.198~2.168) and rocking or patting baby to sleep (OR=3.397,95%CI:2.419~4.768).
