Correlates of preschoolers’ screen time in China: parental factors

BACKGROUND: With the advent of the electronic age, the prolonged screen time (ST) of preschoolers in China is relatively high and is on the rise, which is likely to affect preschoolers’ physical and mental health. This study aimed to explore the factors influencing ST in preschoolers, especially the role of parental factors, and to provide a basis for the prevention, control, and intervention of ST in preschoolers in China. METHODS: A questionnaire was completed by the parents of 1,546 preschoolers from four kindergartens in Pinghu City, Zhejiang Province, China, and a multivariate logistic regression model was used to analyze the correlates of excessive ST in preschoolers. RESULTS: A total of 43.8% of preschoolers aged 3 to 6 years, of which 50.3% were boys and 49.7% were girls, had > 1 h/day of ST. Older preschoolers, greater screen accessibility, greater frequency of eating in front of a screen, longer ST of parents, and unclear rules of screen-based behavior were the risk factors for ST being > 1 h/day (P < 0.05). After additional adjusting of maternal correlates, the relationship between the ST of fathers and ST of preschoolers was still significant (P < 0.01), and the dose–effect relationship was also observed (P < 0.001). CONCLUSION: Prolonged parental ST (especially of fathers) and lack of rules for screen behavior were independent risk factors for prolonged preschoolers’ ST in this study.
