Correlational study finds bedtime and excessive smartphone use significantly impairs sleep quality in primary school students, highlighting the risk of digital media on child health.
Key Points
To evaluate the relationship between specific characteristics of technology use and sleep quality among primary school-aged children.
Conducted a descriptive correlational survey using parent reports from 600 primary school students.
Assessed sleep quality with the Children's Sleep Habits Questionnaire (CSHQ) alongside screen exposure durations, bedroom device presence, and bedtime media habits.
Identified predictors of sleep disturbance using non-parametric group comparisons and multiple linear regression analysis.
Participants had a mean CSHQ score of 52.79 ± 6.73, with 98.7% scoring above the clinical cutoff for sleep problems.
Bedtime technology use and daily smartphone screen time exceeding 2 hours were significantly associated with elevated CSHQ scores.
Smartphone use greater than 2 hours per day was the strongest independent predictor of poor sleep quality (β = 0.34, p < 0.001).
