| Sumario: | Background: Children's time spent in front of screens continues to increase. Parents, health care professionals, educators, and researchers are concerned about this pervasive sedentary behaviour affecting young people's well-being. Increased screen time has also been positively associated with sleep problems, unfavourable behavioural conduct and lower fitness. The escalated duration of screen exposure; delay in bedtime and rise time causes more disruption in sleep behavior. This is also associated with an increased risk of learning and behavioural problems. There has been many attempts to study the relation between children's sleep duration and behavior with screen time. Hence, this study is to find an association between screen time and changes in sleep behaviours and behaviours. Objective: To study the associations of screen time with sleep behaviours and behaviours in typically developing school going children. Study Design: Cross-sectional survey design. Methods: Online Questionnaires based survey was conducted to understand the correlation between screen time, sleep behaviours and behaviours in typically developing school going children age 6 to 16 years. The questionnaires included in the survey were Screen Q, Children Sleep Habit Questionnaire and Corner's Scale. These questionnaires were administered on 74 parents of typically developing children who were well versed in English language and use of Smartphone. Consent was taken from the parents. Questionnaires were sent through email or WhatsApp messages as Google forms to 74 parents, out of which 55 responses were received. Total 51 responses were included in the study which was analyzed to find association of screen time with sleep behaviours and behaviours in typically developing children. Results: The average time spent on screen by typically developing children per week was 17.54 hrs. The average scores obtained on Children Sleep Habit Questionnaire was 57.82. The Pearson's Correlation(r) value was found to be -0.108284 between the associations of screen time with sleep behaviours. The Pearson correlation(r) between screen-time with inattention was 0.223920, with hyperactivity was 0.063886, with defiance was -0.028944, with peer relations was 0.044821, and with executive functions was 0.704613. Conclusion: Therefore, it can be concluded that there is no correlation between screen time use and sleep behaviours and also between screen time with behaviours like inattention, hyperactivity, defiance and peer relations. There seem to be moderate correlation between screen-time with executive functions.
