Abstract: Objective To investigate the current status of screen exposure in children with global developmental delay, and to explore the related factors affecting screen time. Methods From November 2019 to June 2021, 217 children with global developmental delay aged 2 to 5 years in the Department of Developmental and Behavioral Pediatrics, Shanghai Children's Medical Center were enrolled in this study. Their parents completed the screen exposure questionnaire. Then the screen exposure status was described, and the risk factors of screen exposure of children with global developmental delay were analyzed by Logistic regression. Results Totally 80.2% of the children with global developmental delay had their onset age of screen use before 18 months old, and 51.6% of them use screen＞1 h/d. And 37.3% primary caregivers chose to accompany children more than half of the time during screen exposure. Logistic regression analysis showed that high frequency of reading between primary caregivers and children (> 3 days per week) was a protective factor of screen time＞1 h/d in children with global developmental delay (OR=0.246,95%CI:0.129 - 0.469). Not having mother as the primary caregiver(OR=2.055, 95%CI: 1.138 - 3.710) and having screen exposure while eating (OR=2.067, 95%CI: 1.161 - 3.680) were independent risk factors of screen time＞1 h/d in children with global developmental delay. Conclusions A higher percentage of children with developmental delays have more screen time than the guideline recommendations. And the screen time of children is influenced by the primary caregiver and their behaviors. Pediatricians should strengthen the propaganda of proper use of screens so as to prevent children from early and excessive exposure to screen.
