The bidirectional relationship between children's bedtime irregularity & hyperactivity/inattention symptoms: a prospective cohort study.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesAlthough cross-sectional data indicated positive association between hyperactivity and inattention problems and irregular bedtime, longitudinal studies on this topic are scarce leading to no clear inference regarding their directional relationship. Thus, using a prospective birth cohort, we examined the longitudinal relationship between hyperactivity/inattention problems and bedtime irregularity among children aged 5–11 years. STUDY
designWe made use of a nationally representative British birth cohort (N = 15430). Parents reported their children’s hyperactivity/inattention symptoms and bedtime irregularity when the children were aged 5, 7 and 11 years. Data were analyzed using the cross-lagged autoregressive model.
resultsHyperactivity/inattention symptoms (βs = 0.74, ps < 0.001) and bedtime irregularity (0.35 ≤ βs ≤ 0.45, ps < 0.001) remained stable across the 6-year period. Hyperactivity/inattention symptoms and bedtime irregularity consistently predicted each other over time (0.02 ≤ βs ≤ 0.05, ps < .05).
conclusionsOur findings supported a small, yet statistically significant bidirectional relationship between hyperactivity/inattention symptoms and bedtime irregularity during childhood. Findings are consistent with the possibility that regularising bedtime may be associated with improvements on children’s hyperactivity/inattention behaviour. Targeting both hyperactivity/inattention symptoms and bedtime irregularity might be a better approach to optimise overall functioning.
