Trends and Associated Factors of Malnutrition Among Adolescents With Diarrhoea in Bangladesh: A Retrospective Cross-Sectional Surveillance Study Using Adaptive LASSO.
Article in Health science reports, 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 and Aims: Adolescence is a critical phase of rapid growth with long-term health implications. We aimed to examine the trends and associated factors of malnutrition among adolescents with diarrhoea in urban Bangladesh. Methods: We conducted a retrospective cross-sectional study and analysed data from 1597 adolescents aged 10-19 years enrolled in the Diarrhoeal Disease Surveillance System at icddr,b's Dhaka Hospital between 2012 and 2023. Nutritional status was defined using WHO standards. Trends were assessed using the Jonckheere-Terpstra test. Logistic regression models were developed after variable selection with least absolute shrinkage and selection operator. Results: The pooled prevalence of stunting, thinness, and overweight across 2012-2023 was 473/1597 (29.6%), 388/1597 (24.3%), and 106/1597 (6.6%), respectively. Stunting declined significantly from 40.8% in 2012 to 25.7% in 2023, while thinness increased from 21.8% to 24.3%. In adjusted models, stunting was positively associated with age (aOR: 1.06; 95% CI: 1.02-1.10) and negatively with maternal post-primary education (aOR: 0.71; 95% CI: 0.53-0.94) and rich households (aOR: 0.66; 95% CI: 0.46-0.96). Thinness was less likely among females (aOR: 0.46; 95% CI: 0.35-0.60), older adolescents (aOR: 0.90; 95% CI: 0.86-0.94), and the richest households (aOR: 0.52; 95% CI: 0.30-0.90). Overweight was inversely associated with age (aOR: 0.92; 95% CI: 0.86-0.99) but increased with post-primary maternal education (aOR: 3.22; 95% CI: 2.09-4.96) and richest households (aOR: 2.72; 95% CI: 1.13-6.55). Conclusion: Adolescent stunting decreased while thinness increased over the 12-year period, highlighting a dual burden of malnutrition. Male adolescents and those from socioeconomically disadvantaged households remain particularly vulnerable to malnutrition. These findings underscore the need for integrated adolescent nutrition strategies within diarrhoeal disease management and urban health programmes in Bangladesh.
