Evening media exposure reduces night-time sleep.
AIM
To investigate whether evening media exposure, bedroom media use and night-time sleep duration at age 6 months are associated with night-time sleep duration in 12-month-old Thai infants.


METHODS
We enrolled 208 infants in this study at 6 months of age. They were followed-up at 12 months of age. A sleep diary was used to document the infant's sleep onset and wake time at each visit. Night-time sleep duration was then calculated at both ages. Screen media exposure in the household was assessed in depth at both visits.


RESULTS
Infants who were exposed to screen media in the evening at 12 months of age had a 28-min decrease in 12-month night-time sleep duration on weekdays. Moreover, infants who were exposed to screen media in the evening at age 6 months and 12 months had shorter 12-month night-time sleep duration compared with those who were not exposed to screen media after 7 pm at both ages. Night-time sleep duration at 12 months of age was also directly related to 6-month night-time sleep duration.


CONCLUSION
Infants exposed to screen media in the evening at 12 months of age had decreased 12-month night-time sleep duration. To promote good sleep hygiene and optimal sleep for infants at this age, screen media exposure after 7 pm should be avoided.
