Abstract
Background/Objectives: Excessive screen time and inadequate sleep are well-established developmental risk factors, yet limited research has examined the relationship between adherence to national sleep and screen time guidelines and language outcomes in children with mild language delays. This study examined sleep, screen time, and language outcomes in 765 children aged 1–5 with mild language delays enrolled in the Early Discovery Program. Methods: Sleep and screen time were categorized according to American Academy of Pediatrics and Caring for Our Children guidelines. Language outcomes were measured using standardized scores from the Preschool Language Scales–Fifth Edition. Results: Sociodemographic factors, including race, insurance status, and caregiver education, were significantly associated with sleep and screen behaviors. Excessive screen time was negatively associated with expressive language scores, while sleep duration showed no significant relationship. Conclusions: Findings highlight the need for early interventions that promote adherence to national health guidelines and address sociodemographic factors influencing language development in young children.
