Overweight and obesity among youth in a city in Western Amazonia: a time trend analysis from 2006 to 2024 of the largest geographic capital of Brazil.
Article in Public health nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveOverweight and obesity have become a global public health concern, with prevalence rising sharply in low- and middle-income countries. This study analysed temporal trends in overweight and obesity among schoolchildren in the largest capital city of Brazil, from 2006 to 2024.
designRepeated cross-sectional.
settingSchoolchildren aged 6 to 19 years from Porto Velho, Rondônia, Brazil.
participantsA total of 12 646 participants were evaluated. To assess the BMI
resultsOverall, 17·8 % of participants were classified with overweight, and 8·6 % were classified with obesity. The study also found that obesity prevalence was consistently higher among younger age groups compared to adolescents. The results revealed a significant increase in obesity prevalence among girls (annual percentage change (APC) = 5·81 %; 95 % CI = 1·03-10·81;
conclusionsOur findings indicate rising obesity among girls and children aged 6-10 years and support the need for urgency. We recommend targeted action, including implementing mandatory quality physical education and school nutrition standards, enforcing restrictions on marketing to children and prioritising municipal policies that increase access to healthy foods.
