Conclusions

The incidence of allergic asthma is highest in early childhood and steadily decreases during adulthood, while the incidence of non-allergic asthma is low until it peaks in late adulthood. After 40 years of age most new cases of asthma are non-allergic. This study supports the concept that late-onset asthma is a separate entity and the mechanisms behind it differ from asthma beginning in childhood or in early adulthood.
