Why are asthma rates increasing?

Increased obesity in general has been suggested as a contributing factor for the increase in asthma prevalence. Some experts believe rising rates of asthma may, in part, be due to a deficiency of vitamin D. Vitamin D is essential for lung and immune system development.

Is incidence of asthma increasing or decreasing?

The increase is associated with urbanization and has been documented particularly among children and teenagers in urban areas of middle- and low-level income countries. Use of validated questionnaires has enabled comparisons of studies.

Suggestions include the following: Children are being exposed to more and more allergens such as dust, air pollution and second-hand (and even third-hand) smoke.

Is asthma genetically inherited?

Asthma runs strongly in families and is about half due to genetic susceptibility and about half due to environmental factors (8, 9). The strong familial clustering of asthma has encouraged an increasing volume of research into the genetic predisposition to disease.

Other biological changes, notably shifts in patterns of inflammation, may reduce older patients' response to inhaled corticosteroids that need to be taken daily.
