Global, regional, and national epidemiology of otitis media in children from 1990 to 2021
Bibliographic record
Abstract
Background: Otitis media(OM) is a prevalent ear condition, particularly among children, with a significant impact on quality of life. This study aimed to elucidate the global prevalence and disability-adjusted life years (DALYs) associated with OM in the 0-14 age group from 1990-2021, using data from the 2021 Global Burden of Disease (GBD) study. Methods: Our study conducted a comprehensive analysis of OM data from the GBD 2021 report, examining the prevalence and DALYs related to OM across 204 countries and territories over a 32-year period. Data were stratified by age, sex, year, geographic region, and sociodemographic index (SDI). Temporal trends were evaluated using estimated annual percent change (EAPC) calculations. Additionally, a global risk attribution analysis for childhood OM was conducted, and a Bayesian age-period-cohort (BAPC) model was applied to project the global burden of childhood OM from 2021-2035. Results: In 2021, the global burden of OM in children remained significant, with an incidence of 297,243,470 cases and an age-standardized prevalence of 14,775 cases per 100,000 population. OM resulted in 1,035,749 DALYs globally, with an age-standardized DALY rate of 51.48 per 100,000 population. Regionally, the highest age-standardized prevalence of OM was observed in Eastern Sub-Saharan Africa, South Asia, and Western Sub-Saharan Africa, while Central Europe, East Asia, and High-income Asia Pacific exhibited the lowest prevalence. Key risk factors identified include secondhand smoke, particulate matter pollution, low birth weight, and short gestation. Additionally, a significant inverse association was found between the SDI and the burden of OM, with age-standardized DALY rates decreasing markedly as SDI increased. Conclusion: OM in children represents an escalating global health challenge, marked by a rising incidence. Although there has been a global decline in DALYs, the burden of DALYs associated with OM in children remains significant, particularly in regions with a low SDI. A more comprehensive understanding of the epidemiology of OM in children could enhance prevention and control efforts.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
