Abstract
BACKGROUND: There is a paucity of epidemiological data on asthma classified by disease severity in France. The ASTHMAPOP cross-sectional study aimed to review the prevalence and current management of asthma in people aged ≥18 years in France. METHODS: A self-administered questionnaire was mailed to 19 676 people representative of the French population in age, gender, region, and socio-economic status. Asthma was classified by treatment steps per the 2017 Global Initiative for Asthma (GINA) report, according to prescribed treatments. Analyses were mostly descriptive. RESULTS: The questionnaire return rate was 81.7% (n = 16 083), and 15 587 questionnaires were analyzed. The prevalence of lifetime asthma was 12.8% (95% confidence interval (CI):12.3-13.3%; n = 1 989) in 2018. The prevalence of current asthma (i.e., 12 months before the survey) was 6.4% (95% CI: 6.0-6.8%; n = 993); most of these respondents (95.3% [n = 946]) were receiving asthma treatment, and 49.4% (n = 491) were treated for mild asthma (GINA step 1 or 2). Of people with current asthma, 47.6% reported ≥1 asthma exacerbation in the past 12 months-defined as episodes (several days) during which symptoms (cough, sputum, and dyspnea) were worse than usual; 14.3% had ≥1 emergency visit, and 3.1% had ≥1 hospitalization due to asthma. Of those taking continuous asthma controller medications who answered all Morisky Medication Adherence Scale questions (n = 501), 46.4% were adherent (score=4) to their treatment regimen. Based on the 6-item Asthma Control Questionnaire scores, asthma was partially controlled or uncontrolled in 47.7% of 969 people. CONCLUSIONS: The prevalence of asthma in France has remained stable since 2006, but levels of asthma control and treatment adherence continue to be relatively poor. Asthma management in France requires improvement.
