Abstract Objective To explore the current status of sleep and influencing factors among infants in Shanghai, and provide reference for the prevention and intervention of infants’ sleep problems. Methods A total of 457 infants aged 0-35 months, who underwent medical inspection in the Child Health Clinic of Maternal and Child Health Care Hospital of MinhangDistrict of Shanghai, were enrolled. Their parents completed the brief infant sleep questionnaire（BISQ）and the general information questionnaire. Univariate factor and Logistic regression were used to analyze the influencing factors of various sleep problems. Results The average sleep time of the infants was（3.95±2.20）h during daytime,（9.41±1.32）h atnight, and（13.37±2.28）h per day, respectively. The infants’ daytime and full day sleep time decreased with age rising（P<0.05）, but the night sleep time increased with age rising（P<0.05）. The proportion of infants whose full day sleep time was in the recommended range was 83.6%, which gradually increased with age rising. The incidence of sleep problemsin all infants was 54.70%, with highest incidence on difficulty in falling asleep（28.45%）, followed by nocturnal awake（19.69%）andsleeprhythm disorder（17.94%）,andthesleep breathingproblemwas the lowest（4.16%）.The univariate factor analysis showed that age, current feeding way, room brightness, room temperature, sleeping room, sleeping bed, and ways to fall asleep were associated with sleep problems. Logistic regression analysis showed that appropriate room temperature（OR=0.21, P=0.045）and not sleeping alone（OR=2.48, P=0 .005）were significant predictors to sleep problems. Conclusion Sleep problems are common among infants aged 0-35 months in Shanghai. It is suggested to strengthen science education related to sleep health knowledge, and guide the parents to provide suitable sleep environment and help infants establish good sleep habits for promoting sleep health.
