Effectiveness of bilingual health education on obesity and dietary behaviors in Mongolian adolescents: a six-month intervention 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
Background: Obesity among adolescents has become a global public health concern. Previous studies have shown that multidimensional interventions, such as school-based programs, health education, and guidance on diet and physical activity, effectively improve obesity in adolescents. However, there is a lack of research on bilingual health education interventions in minority language environments in rural and pastoral areas of China. Based on a 2023 field survey of students from three Mongolian middle schools in Ar Horqin Banner, Chifeng City, Inner Mongolia, this study evaluated the effect of a 6-month Mongolian-Chinese bilingual health education intervention on obese adolescents' BMI Methods: Baseline data, including height, weight, and a dietary behavior questionnaire, were collected from 2,210 Mongolian middle school students, of whom 155 obese students were screened out. A 6-month bilingual health-education intervention was implemented for the 155 obese students, with content covering guidance on a rational diet, cultivation of healthy behaviors, and moderate exercise training. Before and after the intervention, the participants underwent height and weight measurements, fasting blood sampling, and completed questionnaires. This study evaluated the intervention effects by examining changes in BMI Results: Among 2,210 adolescents, the prevalence of overweight and obesity was 13.12 and 7.01%, respectively (combined 20.13%). These rates were significantly higher among males and junior high school students ( Conclusion: Bilingual health education effectively improved dietary behavior and metabolic indicators in adolescents with obesity. Although the 6-month intervention did not significantly alter overall BMI
