Association Between Screen Time of Mobile Devices and TV and School Readiness in Preschool Children: A Cross-Sectional Study.

We aimed to investigate the relationship between screen time and school readiness. A total of 80 ppreschool children were included. Parents were interviewed about their children's daily screen time. The Metropolitan Readiness Test was utilized. Results showed that the school readiness of those with a total screen time of 3 hours or less was significantly higher. TV time was inversely associated with reading readiness (B=- 2.30, p  < .001), whereas mobile device time was inversely associated with both reading (B = -0.96, p  = .04) and numbers readiness (B = -0.98, p  = .02). This study point to the importance of supervising children's screen use, and of awareness of parents and professionals.
