Tuberculosis-associated respiratory impairment and disability in children and adolescents: a systematic review
Bibliographic record
Abstract
Background: While the immediate effects of pulmonary tuberculosis are well-documented, respiratory impacts persisting beyond treatment, particularly in children and adolescents, are less understood. This systematic review aimed to evaluate the current evidence on tuberculosis-associated respiratory impairment and disability in children and adolescents following tuberculosis treatment. Methods: We searched MEDLINE, Embase, CENTRAL, Global Index Medicus, and preprints from January 1, 2004, to December 5, 2024, to identify studies enrolling children (0-9 years old) or adolescents (10-19 years old) who completed treatment for microbiologically confirmed or clinically diagnosed pulmonary tuberculosis. Eligible studies measured at least one tuberculosis-associated respiratory impairment or disability outcome. Data were analyzed descriptively and stratified into three age groups based on median age of tuberculosis diagnosis: <5 years, 5-10 years, and >10 years. This study was prospectively registered (PROSPERO CRD42024529906). Findings: We identified 117 studies reporting tuberculosis-associated respiratory impairment or disability outcomes. Of those, five met our inclusion criteria, as over 80% of the identified studies excluded children and adolescents. Following tuberculosis treatment, children and adolescents exhibited significant respiratory impairments. In children <5 years of age, impairment included reduced tidal volume and peak tidal expiratory flow. Among those 5-10 years, approximately 40% exhibited abnormal lung function post-treatment, increasing to 65% in adolescents >10 years. Disability was frequently reported, with 35-50% of children and adolescents experiencing respiratory symptoms and children <10 years showing reduced growth metrics and a diminished quality of life. Interpretation: Even after successful tuberculosis treatment, children and adolescents can experience respiratory impairments and disability that may reduce their quality of life, ability to participate in activities, and growth potential. The epidemiology and clinical manifestations of these impairments vary by age, reflecting distinct biological and behavioural differences. Future research should prioritize these younger populations to ensure their unique needs and challenges are adequately represented. Funding: The Robert E.

How this classification was reachedexpand
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.
