Abstract

Nocturnal media use has been linked to adolescents' sleeping problems in cross-sectional studies which do not address reverse causality. To prospectively assess the new occurrence of sleep problems or health symptoms in relation to electronic media use and nocturnal mobile phone use, we used data from the longitudinal Swiss HERMES (Health Effects Related to Mobile phone usE in adolescentS) cohort on 843 children from 7th to 9th grade. Logistic regression models were fitted and adjusted for relevant confounders. Adolescents reporting at baseline and follow-up at least one nocturnal awakenings from their own mobile phone per month were more likely to have developed restless sleep (Odds Ratio (OR): 5.66, 95% Confidence Interval: 2.24⁻14.26) and problems falling asleep (3.51, 1.05⁻11.74) within one year compared to adolescents without nocturnal awakenings. A similar pattern was observed for developing symptoms, although somewhat less pronounced in terms of the magnitude of the odds ratios. With respect to high screen time at baseline and follow-up, associations were observed for falling asleep (2.41, 1.41⁻4.13), exhaustibility (1.76, 1.02⁻3.03), lack of energy (1.76, 1.04⁻2.96) and lack of concentration (2.90, 1.55⁻5.42). Our results suggest a detrimental effect of screen time and mobile phone-related awakenings on sleep problems and related health symptoms. However, the results should be interpreted cautiously with respect to adolescents' natural changes in circadian rhythm, which may coincidence with an increase in mobile phone and media use.

  • The evidence on which guidelines to stop using screens 1 to 2 hours before bedtime are based largely comes from cross-sectional studies with many inherent limitations.

    From Screen Use at Bedtime and Sleep Duration and Quality Among Youths (2024) · cites this paper as [12]

    The Abstract says earlier cross-sectional studies linked nocturnal media use to adolescent sleep problems but could not address reverse causality. The Discussion calls this one of the few longitudinal studies on electronic media use and sleep. However, the paper does not establish that guidelines to stop using screens 1–2 hours before bedtime are based largely on those studies. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
