Association between temperament and screen time in toddlers
Objective To explore the association between toddlers'temperament and screen time.Methods In the Chinese Family Panel Studies(CFPS)database,1118 toddlers with normal physical development,complete data from the temperament questionnaire survey and weekly screen time in 2020 were included as study subjects.Multiple linear regres-sion models were used to analyze the association between toddlers'temperament scores on five dimensions(activity,social inhibition,reactivity,emotionality,and preoccupation)and weekly screen time.Sensitivity analysis and subgroup analysis were performed by using multiple logistic regression models and stratified analysis.Results After adjusting for toddlers'age,sex,region,urban/rural,parental education level,and depression,each one-point increase in scores of toddlers'activi-ty,reactivity,emotionality,and preoccupation was associated with a longer weekly screen time by 11.2％(95％CI:0.058-0.167,P＜0.001),10.2％(95％CI:0.050-0.155,P＜0.001),7.9％(95％CI:0.027-0.132,P=0.003),and 11.2％(95％CI:0.056-0.168,P＜0.001),respectively.The associations above were not differed by subgroups(P for interaction＞0.05).There was no evidence showed association of toddlers'social inhibition score with weekly screen time(P＞0.05).The results of sensitivity analysis were consistent with the main results.Conclusion High-er activity,reactivity,emotionality,and preoccupation among toddlers are associated with longer screen time.Our study provides a scientific basis for personalized guidance of toddlers'screen use based on their temperament in the future.
