Screen time and sleep problems in South Indian preschoolers: a community-based cross-sectional study
In this large population-based study, two of the five preschool children experienced sleep problems, with excess screen time, particularly screen use in bed, being the key contributing factor. This is one of the few Indian studies to establish an ROC-derived screen time threshold for identifying sleep problems. These findings can guide targeted parental advice and early preventive strategies to promote healthy sleep in preschool children.
