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).
