Screen Time in Indian Children by 15-18 Months of Age.

Objective: To determine the prevalence and practices of exposure to screen-based media in children by 15-18 months of age.

Methods: This observational descriptive study was conducted from March to August, 2019. Mothers of 370 healthy developmentally normal children (15-18 months of age) were enrolled during their visit to immunization clinic of a medical college affiliated hospital. Parental response to a semi-structured questionnaire was recorded to assess the initiation, frequency and duration of screen exposure, and related parental perceptions.

Results: 369 (99.7%) children were exposed to screen-based media till 18 months of age, starting from median (IQR) age of 10 (8, 12) months. Smartphone and television were being viewed by 354 (96%) and 328 (89%) children, respectively. Screen time was >1 hour/day in 328 (88.7%) and >2 hours/day in 209 (56.5%) children (median (IQR): 120 (80, 180) minutes/d). Most (72%) parents were not concerned with their child's screen time.

Conclusion: Almost all young children seem to be exposed to screen-based media by 18 months of age in the urban setting. Extensive use of screen-based media by young children calls for formulation of guidelines on toddlers' screen use and their dissemination to parents.
