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)
