Status of screen use and its association with core symptoms in children with autism spectrum disorder
Objective To investigate the status quo of long-term screen use in children with autism spectrum disorder(ASD)and its correlation with core symptoms,in order to help children establish correct screen use habits.Methods A total of 136 ASD children aged 2 to 5 diagnosed from March 2022 to November 2022 were selected into this study from Longgang District Maternal and Child Health Hospital of Shenzhen City.Status of screen time in ASD children was investigated by a self-made questionnaire.The core symptoms and cognitive status of ASD children were evaluated by the Children's Autism Rating Scale(CARS),Autistic Children's Behavior Scale(ABC),Social Communication Scale(SCQ),and Neuropsychological Development Scale for children aged 0-6 years.Results Totally 62.2％(74/119)of ASD children watched TV/smartphone or tablet,79.8％(95/119)of ASD children began to use screens before the age of 2,46.2％(55/119)of ASD children had screen exposure＞2h/d initially.There were significant differences in CARS score,interaction dimension score of ABC,SCQ total score and social interaction dimension score of SCQ between the screen exposure group(screen time＞2h/d)and the non-screen exposure group(screen time＜2h/d)(t=2.231,2.475,2.131,2.076,P＜0.05).There were statistically significant differences in the scores of CARS,ABC total score,exercise dimension score of ABC,self-care ability dimension score of ABC and social interaction dimension score of SCQ of children in high-risk group(screen use time＞2h/d in children＜2 years old)and non-high-risk group(t=3.021,2.621,2.828,2.847,2.050,P＜0.05).Linear regression analysis showed that screen exposure was positively correlated with CARS,interaction score of ABC,SCQ total score,and social interaction score of SCQ(b=1.41,3.05,2.53,1.56,P＜0.05).High risk was positively correlated with CARS,ABC score and social interaction score of SCQ(b=1.53,6.17,1.27,P＜0.05).Conclusions During the normalization of CO VID-19,preschoolers with ASD have longer screen time.Early prolonged screen time may be associated with core symptoms of ASD.
