Multivariate regression modelling reveals that geographical
region and residing near industrial plant, gas station,
dumpsite, or construction sites are predictors of asthma
(Table 5). Exposure to tobacco is a predictor of asthma and
respiratory symptoms. Residential humidity is a predictor
of wheeze whereas exposure to residential pests (e.g., cockroaches,
rodents) is a predictor of dry nocturnal cough. Having
someone in the household who is regularly involved in
arts/crafts/ceramics/stained glasswork/similar hobbywork is
a predictor of both chronic bronchitis and emphysema. Concern
over air pollution, having ever smoked, and purposely
smelling gasoline fumes/glue/corrector/car exhaust/burning
black ants are significant predictors of wheeze and dry cough.
Ethnicity is a significant predictor of chronic bronchitis
and asthma. Finally, diagnosis with chronic bronchitis and
reporting wheeze are significant predictors of emphysema.
