Abstract
Background: Several regions around the world continue to see increases in the prevalence of asthma and its symptoms; however, in our population the studies are scarce.On the other hand, the population of late adolescents has rarely been analyzed.Thus, this study was conducted to determine the trend of the prevalence of asthma and its symptoms in late adolescents over a period of 7 years.Methods: Two cross-sectional population-based studies were conducted in 2009 and 2016 in Mexican adolescents, aged 15-18 years.Prevalence of asthma and its symptoms, allergic rhinitis and atopic dermatitis were compared between both studies.The data was obtained through the questionnaire proposed by The International Study of Asthma and Allergies in Childhood.An analysis for linear trend for proportions (Mantel-Haenszel) was performed.Results: In 2009, 1600 adolescents were included, and in 2016, 1992 were included.In general, the presence of wheezing at any time during the previous year increased significantly between 2009 and 2016 (12.8% vs. 20.1% and 7.3% vs. 10.3%, p < 0.001 and 0.002, respectively).The prevalence of asthma increased from 7.8% in 2009 to 12.7% in 2016 (p < 0.001).In addition, the prevalence of allergic rhinitis (4.5% vs 9.0%) and atopic dermatitis (3.8% vs 5.2%) also suffered marked increases (p < 0.001 and 0.042, respectively).Conclusions: The prevalence of asthma and some of its symptoms in late adolescents increased substantially in the previous 7 years.

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; both teacher heads agree on what is shown here.
