Behavioral and sociodemographic correlates of sleep duration among children in Samoa.
Article in Sleep health, 2025. 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
objectivesTo describe sleep duration, adherence to sleep recommendations, and behavioral and sociodemographic correlates of sleep among Samoan children.
methodsIn a longitudinal cohort study of Samoan children aged 2-9years (n = 481; 50% female), primary caregivers reported usual number of hours of nighttime sleep during 2015, 2017/2018, and 2019/2020 data collection waves. Associations between behavioral and sociodemographic characteristics and sleep duration were assessed using generalized linear and mixed effect regressions.
resultsAverage reported hours of nighttime sleep for toddlers (age 2) was 9.7 ± 1.1 (SD); for preschoolers (age 3-5) 9.5 ± 1.0, and for school-age children (age 6-9) 9.4 ± 1.3, with 58% of children meeting sleep recommendations. Living in a lower income household was associated with 30 more minutes of sleep for toddlers (adjusted β:0.56 [95% CI: 0.03, 1.09]) and preschoolers (adjusted β:0.51 [95% CI: 0.17, 0.85]), while higher reported physical activity was associated with longer sleep for school-age children (adjusted β:0.49 [95% CI: 0.08, 0.91]). Preschoolers with a primary caregiver who did not complete high school had shorter sleep (β: -0.80 [95% CI: -1.12, -0.48]). Among school-aged children, shorter sleep was associated with greater total carbohydrate intake (for every 100 g/day, β: -0.01 [95% CI: -0.02, 0.01]) and neotraditional dietary pattern adherence (β: -0.27 [95% CI: -0.53, -0.01]).
conclusionsEfforts should be made to encourage adequate sleep among Samoan children. Correlates of sleep were largely consistent with existing literature. Future research should examine additional culturally and contextually-specific risk factors for insufficient sleep in Samoa and consequences for child health.
