Objective To longitudinally examine characteristics and associated factors of parental sleep arrangements for infants aged 0-3 months,in order to provide reference for the predictive guidance of infants' early parental sleep arrangements. Methods This was a longitudinal study of 156 infants with repeated measures from birth to 3 months in 5 cities of China from 2013 to 2015. The parental sleep arrangements were measured at 14 days,1 month,2 months and 3 months after birth. The statistical description and CMH chi-square test were conducted. The generalized linear mixed models were fitted to analyze the associated factors. Results The proportions of infants who fell asleep at night by parents holding,patting or accompanying beside the bed,and alone were 54. 4%,35. 9% and 9. 7%,respectively,and the proportion of falling asleep by holding increased over time (P<0. 000 1). The proportions of asleep,drowsy but awake and fully awake when the infants were placed on the bed at bedtime were 63. 7%,28. 6% and 7. 7%,respectively,and the proportion of drowsy but awake decreased over time (P=0. 000 3). The proportions of co-sleeping,room-sharing without bed-sharing,slept on parents' arms or backs and in a separate room were 53. 8%,42. 4%,2. 0% and 1. 8%,respectively,and the proportion of co-sleeping increased over time (P<0. 000 1). Parents' education level of university and above,household income of 5 100~8 000 yuan and father depression were statistically significant on sleep arrangements(OR=0. 46,2. 55,1. 60,0. 57,P<0. 05或<0. 001). Conclusions Parental sleep arrangements for infants in early stage mainly include falling asleep with soothing,putting infants to sleep asleep and co-sleeping,which need to strengthen predictive guidance.
