Description:Background
The study evaluated the change in the prevalence of airflow obstruction in the U.S. population 40–79 years of age from years 1988–1994 to 2007–2010.
Methods
Spirometry data from two representative samples of the U.S. population, the National Health and Nutrition Examination Surveys (NHANES) conducted in 1988–1994 and 2007–2010, were used. The American Thoracic Society/European Respiratory Society (ATS/ERS) criteria were used to define airflow obstruction.
Results
Based on ATS/ERS criteria, the overall age-adjusted prevalence of airflow obstruction among adults aged 40–79 years decreased from 16.6% to 14.5% (p < 0.05). Significant decreases were observed for the older age category 60–69 years (20.2% vs. 15.4%; p < 0.01), for males (19.0% vs. 15.4%; p < 0.01), and for Mexican American adults (12.7% vs. 8.4%; p < 0.001). The prevalence of moderate and more severe airflow obstruction decreased also (6.4% vs. 4.4%; p < 0.01). Based on ATS/ERS criteria, during 2007–2010, an estimated 18.3 million U.S. adults 40–79 years had airflow obstruction, 5.6 million had moderate or severe airflow obstruction and 1.4 million had severe airflow obstruction.
Conclusions
The overall age-adjusted prevalence of airflow obstruction among U.S. adults aged 40–79 years decreased from 1988–1994 to 2007–2010, especially among older adults, Mexican Americans, and males.
