Abstract
The association between screen time and attention deficit hyperactivity disorder (ADHD) has been controversial. This study sheds light on the contentious correlation between screen time and ADHD. Until August 2022, electronic searches of the PubMed, Embase, and Web of Science databases were carried out. The combined effect value odds ratios (OR) and 95 % confidence interval (95 % CI) were calculated forthe meta-analysis using Stata 12.0. There were 81,234children in the nine studies that made up this meta-analysis which included 28,997 children with ADHDand 52,237 healthy controls. When compared withthe screen time <2 h/d, theOR (95 % CI) value of screen timeand ADHD in the screentime≥2 h/d group was 1.51 (1.20-1.90). Based on the current meta-analysis results, our study found a positive correlation between screen time and the risk of ADHD. Excessive screen exposure may significantly contribute to the development of ADHD in children. Therefore, it is necessary to reduce screen time per day in children to prevent the occurrence of ADHD.
