Prevalence, risk factors and underdiagnosis of asthma and wheezing in adults 40 years and older: A population-based study

Abstract

We described the epidemiologic situation of asthma in adults 40 years and older in Colombia. In addition to some recognized risk factors, our data supports the association of indoor wood smoke and occupational exposures with asthma and wheezing. Underdiagnosis of asthma in adults was high, particularly in older subjects.
