Concomitant associations of dietary behaviours and physical activity with body composition in adolescents.
Article in BMC public 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
backgroundDevelopment of adolescent obesity is associated with substantial health risks and comorbidities and thus represents a major public health concern. This study aimed to examine the associations between dietary behaviours and physical activity with body composition indicators among Slovak adolescents.
methodsWe used data from the Health Behaviour in School-Aged Children (HBSC) study conducted in 2022 in Slovakia. The sample consisted of 1225 adolescents (mean age 13.3 ± 1.4; 53.9% boys). The HBSC questionnaire items were used to assess frequency of fruits, vegetables, sweets, soft and energy drinks, breakfast consumption during weekdays, having breakfast with family, moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA). Body height (cm) was measured using a SECA 213 portable stadiometer, and body composition was assessed via bioimpedance analysis (InBody 230). Linear regression was used to test associations between dietary behaviours and physical activity variables and body composition outcomes.
resultsMore frequent breakfast eating during weekdays and more frequent sweets consumption were inversely associated with body mass index (BMI), percentage of body fat (PBF), visceral fat area (VFA) and fat-free mass index (FFMI). Higher MVPA was inversely associated with BMI, PBF and VFA but positively associated with FFMI. Greater VPA was associated with PBF and VFA, but inversely associated with FFMI.
conclusionsThese findings suggest that more frequent breakfast consumption and moderate-to-vigorous physical activity are associated with favourable body composition parameters in adolescents.
