55% of patients with moderate-to-severe asthma have uncontrolled disease

In a recent survey of 1800 asthma patients in the U.S., more than half (55%) reported that their disease was uncontrolled. A large proportion of patients with controlled asthma (74%) and patients with uncontrolled asthma (65%) reported never receiving an asthma action plan.

Factors independently associated with an increased risk of uncontrolled asthma were:
  • younger age
  • Hispanic race
  • male sex
  • lower income
  • lower education
  • chronic sinusitis
  • high blood pressure
  • gastroesophageal reflux disease (GERD)
