Adolescent loneliness and social isolation as predictors of 24-h movement guidelines adherence into adulthood: a prospective study.

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
backgroundLoneliness and social isolation are psychosocial factors linked to adverse health outcomes in adolescence, but their associations with the integrated 24-h movement guidelines, covering physical activity, screen time, and sleep, remain poorly understood, particularly over the life course. The aim of the study was to examine the associations of loneliness and social isolation with adherence to the 24-h movement guidelines during adolescence and in sustained patterns from adolescence into adulthood over a 22-24-year follow-up.
methodsWe analyzed longitudinal data from individuals who participated in Waves I (1994-1995, n = 20,603) and V (2016-2018; n = 10,979) of the Add Health study. Loneliness (single CES-D item) and social isolation (frequency of peer interactions) were assessed in adolescence (ages 12-17). Adherence to movement guidelines was self-reported at both waves. Generalized linear models with Poisson regression estimated relative risks (RR) for cross-sectional and sustained (adolescence-to-adulthood) adherence.
resultsAt baseline, loneliness was reported by 8.4% and social isolation by 9.4% of adolescents. In women, loneliness was associated with lower adherence to physical activity (RR = 0.87; 95%CI 0.77-0.99), sleep (RR = 0.86; 95%CI 0.79-0.94), and all 24-h movement guidelines (RR = 0.68; 95%CI 0.51-0.90), with associations for sleep (RR = 0.77; 95%CI 0.65-0.91) and all guidelines (RR = 0.37; 95%CI 0.10-0.91) persisting into adulthood. In men, loneliness was associated with lower adherence to sleep (RR = 0.87; 95%CI 0.78-0.97) and all guidelines (RR = 0.78; 95%CI 0.59-0.92), with similar associations observed longitudinally. Social isolation was strongly associated with lower physical activity in both sexes (women: RR = 0.59; 95%CI 0.46-0.75; men: RR = 0.48; 95%CI 0.38-0.61) and with adherence to all guidelines (women: RR = 0.61; 95%CI 0.43-0.87; men: RR = 0.69; 95%CI 0.51-0.93), both cross-sectionally and longitudinally.
conclusionsAddressing loneliness and social isolation as distinct, yet complementary, correlates of movement behaviors may enhance the effectiveness of strategies aimed at promoting healthier movement patterns and supporting social connectedness.
