Can asthma be prevented?
With the increasing prevalence of asthma, numerous studies have looked for risk factors and ways to potentially prevent asthma. It has been shown that individuals living on farms are protected against wheezing, asthma, and even environmental allergies. The role of air pollution has been questioned in both the increased incidence of asthma and in regards to asthma exacerbations.
Climate change is also being studied as a factor in the increased incidence of asthma. Maternal smoking during pregnancy is a risk factor for asthma and poor outcomes. Tobacco smoke is also a significant risk factor for the development and progression of asthma. The development of asthma is ultimately a complex process influenced by many environmental and genetic factors, and currently there is no proven way to decrease an individual's risk of developing asthma.
