The Influence of Social Networks on Adolescent Overweight and Obesity: A Narrative Review.
Review in Nutrients, 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
This narrative review examines the influence of social networks on dietary habits and physical activity, and their relationship to overweight and obesity in adolescents. The study is based on a comprehensive literature search across PubMed, Scopus, EMBASE, PsycINFO, and Web of Science databases, covering the period 2009-2022, and is complemented by a critical analysis of contemporary evidence. The included studies involved adolescents aged 12 to 19 and assessed associations among social networks, body weight, diet, and physical activity, using statistical methods based on social network analysis (SNA). No language restrictions were applied. The results demonstrated that friendship networks significantly influence adolescents' body weight, eating behaviors, and physical activity levels. Specifically, boys exhibited similar unhealthy food consumption patterns within their networks, while girls' networks showed similarities in sedentary activities. This review highlights that adolescents' social networks play a relevant role in weight-related behaviors, with their influence varying based by gender. These findings underscore the need to consider such gender-specific effects when developing prevention and treatment strategies for obesity in this age group.
