Daily short-video watching and online gaming were associated with lower likelihood of insufficient sleep, while daily online shopping was associated with higher likelihood of insufficient sleep among Chinese children and adolescents, with associations varying across demographic subgroups.
Daily short-video watching was associated with a 36% lower likelihood of insufficient sleep compared to never watching short videos.
Daily online shopping was associated with a 24% higher likelihood of insufficient sleep compared to never using online shopping.
Daily online gaming was associated with a 19% lower likelihood of insufficient sleep compared to never playing online games.
No significant associations were found between insufficient sleep and WeChat usage or online learning.
Associations between screen-based sedentary behaviors and insufficient sleep varied across demographic subgroups including gender, educational level, and urban-rural residence.
The study drew on a large nationally representative dataset of Chinese children and adolescents collected across 2020–2022.
This research suggests that not all types of screen-based activities affect children's sleep in the same way. Among over 3,300 Chinese children and teenagers aged 10–18, researchers found that watching short videos and playing online games daily were actually associated with a lower chance of getting insufficient sleep (less than 8 hours), while daily online shopping was linked to a higher chance of not sleeping enough. Activities like using WeChat (a messaging app) or engaging in online learning showed no meaningful relationship with sleep duration. The study also found that these associations were not the same for all groups of children. For example, the potential sleep benefits associated with short videos and gaming were more prominent among boys, rural residents, and middle school students, while the negative association with online shopping was especially notable among younger, elementary and middle school students. This suggests that the relationship between screen time and sleep is more nuanced than a simple 'more screen time equals less sleep' message. This research matters because it highlights that different types of digital activities may have distinct effects on children's sleep, and that one-size-fits-all screen time guidelines may not capture this complexity. Future efforts to protect children's sleep health might benefit from focusing specifically on the types of screen activities children engage in, and tailoring guidance to different groups such as age, gender, and whether children live in urban or rural areas.
