Prevalence of Overweight and Childhood Obesity on an Atlantic Island: A Cross-Sectional Study.
Article in Cureus, 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
Background Childhood overweight and obesity are major public health concerns, with limited recent epidemiological data available for the Azores region, particularly for Terceira Island. Accurate regional prevalence estimates are fundamental for the planning of effective prevention strategies. Therefore, this study aimed to determine the prevalence of overweight and obesity among children and adolescents on Terceira Island and to assess potential associations with age and sex. Methods An observational cross-sectional study was conducted between April and May 2025. The study population included individuals aged five to 18 years registered at Terceira Island's primary health care facility. Participants were selected through simple random sampling, and data on age, sex, and body mass index (BMI) were extracted from clinical records. Corresponding BMI-for-age percentiles were calculated using standardized growth curves. Descriptive statistics and inferential analyses were performed to assess associations, including chi-square tests, Student's t-tests, and logistic regression, with p-values <0.05 considered statistically significant. Results Of 680 individuals initially selected, 136 were excluded due to missing or outdated BMI records, resulting in a final sample of 544 participants (50.6% male). The prevalence of overweight was 41.2%, and obesity was 24.1%. Population-level prevalence estimates with 95% confidence intervals ranged from 37.2% to 45.2% for overweight and from 20.1% to 28.1% for obesity. No statistically significant associations were observed between these conditions and age or sex. These findings suggest a high prevalence of excess weight among children and adolescents on Terceira Island, regardless of age or sex. Conclusion Childhood overweight and obesity are highly prevalent on Terceira Island, and no differences were found by age or sex, highlighting the urgent need for early prevention and intervention strategies to address excess weight in this population.
