Objective: To analyze the correlation between parental involvement and the formation of good eye use behavior in children,and to provide theoretical basis for more accurate prevention and control of myopia. Methods: A total of 2 726 children and their parents from 3 primary schools were selected from April to May 2021 by clustering sampling method. Children s ocular parameters, eye use behavior, general characteristics of parents, and parental involvement were collected through ocular measurements and questionnaires, respectively. Results: Parental involvement was associated with family economic, parental education level, and parental myopic status( P <0.05). Children s myopia risk was associated with parental involvement: lower myopia risk was associated with frequent parental involvement in behavioral management of child sleep and child outdoor activities( P <0.01). Parents who always/frequently participate in the management of children s eye behavior have an average daily screen time of <2 h ( OR= 1.95 , 95%CI =1.31-2.90), and daily outdoor activity time>2 h ( OR=0.78, 95%CI =0.65-0.93), daily sleep time >8 h ( OR= 0.52 , 95%CI =0.40-0.68), daily continuous reading and writing time <1 h ( OR=1.33, 95%CI =1.30-1.56), reading and writing The distance from the desktop > 30 cm ( OR=0.57, 95%CI =0.34-0.95) had a statistically significant effect ( P <0.05). Conclusion High parental involvement may help school age children develop good eye habits and reduce the risk of childhood myopia. Parental involvement is higher among those who had myopia themselves, and parental involvement is positively associated with total household income and parental literacy.
