Abstract: Background: Excessive screen hours and inadequate sleep duration in early life predict a greater likelihood of the later development of psychopathology in childhood and adolescence. Hence, this study was done to evaluate the Correlation between Screen hours and sleep patterns with behavior among school-going children residing in New Delhi. Methods: A cross-sectional study was performed from January to March 2022 among 400 students chosen using a simple random sampling procedure in New Delhi. Data was collected through school teachers based on their observations and analyzed using Epi info version 7. To predict the correlation between screen hours and sleep patterns with the behavior of students, a univariate analysis was done. A p-value of 0.05 was taken as statistically significant. Results: Present study included 180 (45%) females and 220(55%) male school children from New Delhi. Among them, 243(60.8%) were ≤ 10 years while 157(39.2%) were >10 years old. In the present study, 113(28.2%) students had behavior score 10 as assessed by teacher, 107(26.8%) had 9, 95(23.8%) had 8, 37(9.3%) had 7, 26(6.5%) had 6, 14(3.5%) had 5, 3(0.8%) had 4, 2(0.5%) had 3, 1(0.3%) had 2 and 2(0.5%) had behavior score of 1. The mean behavior score was 8.40±1.578 as assessed by the teacher. In the present study, behavior score was significantly more in students who had duration of watching screen per day <2 hours, duration of watching TV on a typical day <2 hours, duration of using a smartphone on a typical day <2 hours, and average duration of sleep per day on a weekday between 6-8 hours, and who didn’t have a habit of watching mobile/TV before sleeping while there was no significant difference between the students on the basis of duration internet surfing, duration of videogames/games on screen per day and duration of onset of sleep after going to bed. Conclusion: The present study concluded that the behavior of school children was significantly associated with the duration of screen hours and the average duration of sleep per day. School children should be advised to limit or reduce screen time exposure, especially before bedtime hours, and to have adequate sleep of 6-8 hours to minimize any potential impacts on their behaviors.
