Abstract:
Objective:To analyze the associations among body mass index (BMI), learning screen/gaming screen exposure and executive function in preschool children in Anhui Province, so as to provide a basis for promoting the development of executive function in preschool children.
Methods:In June 2022, a stratified cluster sampling and convenience sampling methods were used to survey 3 534 mothers of preschool children in Wuhu City, Luan City, and Fuyang City, Anhui Province. The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) was used to assess the preschool childrens executive function abnormalities. Binary Logistic regression was conducted to examine the relationships among BMI, learning screen/gaming screen exposure, and their combined effects on executive function abnormalities.
Results:The detection rate of abnormal executive function in preschool children was 9.65%. Logistic regression analysis showed that after adjusting for the confounding factors such as pregnancyinduced hypertension, primary caregivers, family per capita monthly income and family structure, the risk of abnormal executive function of children in overweight/obesity group and high learning screen/gaming screen exposure group increased significantly (overweight/obesity:OR=1.78, 95%CI=1.31-2.42, learning screen exposure:OR=1.48, 95%CI=1.18-1.86, gaming screen exposure:OR=1.50, 95%CI=1.18-1.91,P<0.05). Compared with children with normal BMI and low learning screen/gaming screen screen exposure, those with both overweight/obesity and high learning screen/gaming screen exposure had a significantly greater risk of executive function abnormalities (OR=2.07, 95%CI=1.29-3.31; OR=2.42, 95%CI=1.59-3.68,P<0.05).
Conclusions:Overweight/obesity and high learning screen/gaming screen exposure are important risk factors for executive function abnormalities in preschool children. Therefore, actively guiding preschool children to develop healthy life habits to promote the normal development of their executive functions is essential.
