Bidirectional associations between accelerometer-based sleep metrics and mental health symptoms from childhood to late adolescence: data from a Brazilian birth cohort.
Article in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundA bidirectional relationship between sleep and emotional/behavioral problems has been suggested in the literature; however, no study has examined this association longitudinally across multiple developmental stages using objective sleep metrics. This study investigated the reciprocal relationship between sleep and emotional/behavioral symptoms and explored the potential existence of critical or sensitive periods within a Brazilian birth cohort.
methodsThe 2004 Pelotas Birth Cohort Study recruited 4231 children (2196 boys) born in 2004 in Pelotas, Brazil. Emotional/behavioral problems were evaluated using the Strengths and Difficulties Questionnaire (SDQ) at 6, 11, 15, and 18 years of age and analyzed as externalizing and internalizing symptoms. Sleep duration and efficiency were evaluated using actigraphs during the mentioned follow-ups. Cross-lagged panel models were used to assess bidirectionality and critical/sensitive periods.
resultsHigher externalizing symptoms at 6 years predicted longer sleep duration (β = 0.032, p = 0.041) and decreased sleep efficiency (β = - 0.034, p < 0.022) at age 18. The association was more evident in early adolescence, from 11 to 15 years β
conclusionsHigher externalizing symptoms predicted poorer sleep efficiency and longer sleep duration, whereas a bidirectional association with an opposite relationship to internalizing symptoms was found. These results highlight that adolescence is a critical point for both associations.
