Prahlad Kadambi, L Sushanth Prabhath Reddy, S. Mohammed Aashiq, Suresh P.


Background: Sleep plays a vital role in good health, growth and well-being. Sleep disorders manifest with disturbance in both quantity and quality of sleep. The current generation of children is growing up surrounded by a world of electronic media through the smartphones and tablets of their parents. Previous studies have shown that sleep disorders are increasing in pediatric age group. This study aimed to assess screen-time, quality and quantity of sleep in children aged 3-15 years.

Methods: Total 104 children were recruited for our cross-sectional study from Meenakshi Medical College Hospital and Research Centre, Kanchipuram. After obtaining consent, Pediatric Sleep Questionnaire (PSQ) was administered after collecting clinical history. Anthropometry and clinical examination was performed.

Results: Total 8 out of 104 children (7.69%) in the study had poor quality sleep (PSQ Score≥5). 48 out of 104 children (46.1%) had deficient quantity of sleep as per American Academy for Sleep Medicine (AASM) recommendations. Children born with low birth weight had comparatively poorer quality of sleep (r=0.331 p=0.015). All 104 children had spent more screen time than permitted for their age.

Conclusions: Quality and quantity of sleep were affected in children aged 3-15 years. This may be attributed to increased screen time but needs to be confirmed in larger studies.
