Asthma may be underdiagnosed in overweight inactive girls

Epidemiological studies suggest that asthma is still underdiagnosed in children and young adults. On p 651 Siersted et al report on a population based study among Danish adolescents in which they examined potential risk factors for underdiagnosed asthma. Asthma was defined independently of the physician's diagnosis as coexisting asthma-like symptoms and one or more positive test results of obstructive airway lability. Undiagnosed asthma comprised about one third of all cases of asthma identified, and two thirds were in girls. Underdiagnosis was associated with conditions that may complicate the diagnostic process, including being overweight and low physical activity, family problems, passive smoking, and the absence of allergic rhinitis.
