Predictors of anthropometric, blood pressure, metabolic analyses, clinical conditions and spirometry results among patients with pediatric exposure to WTC disaster.
| Significant multivariable regression result | Odds ratio/increment (p value) |
|---|---|
| Clinical conditions | |
| Age on 9/11/01 associated with new provider diagnosed asthma | + 16.2% odds/year younger (0.001) |
| Age on 9/11/01 associated with new GERD | + 16.6% odds/year older (0.004) |
| Age on 9/11/01 associated with new headaches | + 10.2% odds/year older (0.011) |
| Laboratory analyses | |
| Residence in home at least 1 day in the period September 11-18, 2001 associated with total eosinophil count | + 64.6/μL (0.027) |
| Residence in home at least 1 day in the period September 11-18, 2001 associated with percent eosinophil count | + 1.37% (0.007) |
| Age on 9/11/01 associated with percent eosinophil count | + 0.098%/year younger (0.023) |
| Home dust exposure associated with HDL | –10.3 mg/dL (0.027) |
| Home dust exposure associated with triglycerides | + 36.3 mg/dL (0.033) |
| Blood pressure | |
| Age on 9/11/01 associated with prehypertension | + 9.5% odds/year older (0.024) |
| Spirometry results | |
| Dust cloud associated with FEV1/FVC | –5.4% (0.032) |
| Dust cloud associated with <5th percentile FEV1/FVC | 15.06 (0.002) |
| Dust cloud associated with MMEF percent predicted | –17.1% (0.034) |
| Dust cloud associated with <5th percentile FVC | 44.36 (0.003) |
| Spirometry pattern | |
| Dust cloud associated with abnormal spirometry | 24.39 (0.0002) |
| Dust cloud associated with isolated low FVC pattern | 21.16 (0.011) |
| Dust cloud associated with obstructive pattern | 7.05 (0.026) |
All results are from multivariable linear/logistic regressions including: residence in home at least 1 day in the period September 11 -18, 2001, home dust exposure, dust cloud exposure (as present/absent for all results, except for PFT results when expressed as absent/dust exposure but not covered in dust/covered in dust), age on 9/11/01 and overweight/obese/normal body mass index (with the exception of eosinophils, for which body mass index was excluded). Results not reported imply p>.05.
