Childhood Asthma Severity Indicators in Relation to Rural DwellingAbstract Number:2159 Joshua Lawson*, Donna Rennie, Roland Dyck, Don Cockcroft, Oluwafemi Oluwole, and Anna Afanasieva Joshua Lawson* University of Saskatchewan, Canada, E-mail Address: [email protected] , Donna Rennie University of Saskatchewan, Canada, E-mail Address: [email protected] , Roland Dyck University of Saskatchewan, Canada, E-mail Address: [email protected] , Don Cockcroft University of Saskatchewan , Oluwafemi Oluwole University of Saskatchewan , and Anna Afanasieva University of Saskatchewan AbstractBackground: Asthma prevalence is thought to be lower in rural locations. However, among children with asthma, some rural exposures thought to protect against the development of asthma could also aggravate the condition. We examined childhood asthma severity between urban and rural dwellers with a focus on specific agricultural exposures.Methods: In 2013 we completed a cross-sectional survey of children (5-14 years) from an urban area (approximately 30,000-210,000) and a rural area (<1,500 or farm dwelling) of Saskatchewan, Canada. Surveys of children's respiratory symptoms and agriculture exposures were completed by parents. Current asthma was defined as a previous doctor diagnosis of asthma along with any of wheeze, asthma episodes, breathing medication use, or health care utilization for asthma in the past 12 months.Results: Of the 3,122 children included in the study, 21% lived in a rural area. Asthma prevalence differed between urban (14.8%) and rural (11.2%) locations (p=0.02). After adjustment for confounders, rural dwelling children were more likely to have wheeze severe enough to limit speech to one or two words between breaths (OR=2.50, 95%CI=1.24-5.03, p=0.01). Rural children were less likely to see a physician once for asthma in the past 12 months (OR=0.46, 95%CI=0.22-0.97, p=0.04) with no association in seeing a physician for asthma >1 time in the past 12 months (OR=1.09, 95%CI=0.60-1.97, p=0.77). Children exposed regularly to hay bales, feeding livestock, and cleaning barns were at increased risk of seeing a physician for asthma >1 time in the past 12 months (ORs >3.00). Children who rode horses regularly were at increased risk of wheezing =4 times in the past 12 months.Conclusions: These results suggest that rural children may under-present to a physician initially or for mild disease resulting in asthma under-diagnosis but once the child has asthma, activities on the farm may aggravate the disease.

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.
