Sleep initiation patterns and their influence on sleep quality in infants and young children

To investigate the current status of sleep initiation patterns, influencing factors for sleep initiation patterns, and the influence of sleep initiation patterns on sleep quality in infants and young children. A total of 521 infants and young children, aged 0-35 months, who underwent physical examination at the outpatient service of the Department of Growth and Development in Shenzhen Bao'an Women's and Children's Hospital Affiliated to Jinan University were enrolled as subjects. A self-designed questionnaire and Brief Infant Sleep Questionnaire were used to collect the information on family background, parenting behaviors, and sleep quality in the past one week. A multivariate logistic regression analysis was used to evaluate the influencing factors for sleep initiation patterns. A multiple linear regression analysis was used to evaluate the influence of sleep initiation patterns on the number of nighttime awakenings. Among the 521 infants and young children, 258 (49.5%) were breastfed/bottle fed to initiate sleep, 62 (11.9%) were rocked/held to initiate sleep, 39 (7.5%) slept independently, and 162 (31.1%) initiated sleep accompanied by parents. The multivariate logistic regression analysis showed that the children with breastfeeding and a younger age were more likely to be breastfed/bottle fed to initiate sleep (
