Objective: Spirometry is recognized as the gold standard assessment for the diagnosis of COPD. However, spirometry continues to be underused, perpetuating the underdiagnosis of COPD. The aim of this study was to evaluate the prevalence of COPD in a primary care setting in patients with a smoking history and self-reported chronic bronchitis symptoms.
Research design and methods: This was a multi-center, cross-sectional study. The primary assessment was the percentage of patients with airway obstruction (post-bronchodilator FEV1/FVC ratio ≤ 0.70) compared to those without obstruction (post-bronchodilator FEV1/FVC ratio > 0.70).
Results: Airflow obstruction consistent with COPD was confirmed in 26% of patients …

Rationale
Previous studies have demonstrated associations of high ozone levels with increased epidemiologic as well as lung function measures of asthma activity.
Objectives
In an observational study during the summer months, we hypothesized that higher ambient ozone levels are associated with more frequent symptoms, higher airway and systemic inflammation, as well as worse lung function in asthmatics as compared with non-asthmatic individuals.
Methods
Thirty-eight asthmatics and thirteen healthy control subjects residing in metropolitan Atlanta were enrolled during peak ozone season. Medical histories, quality-of-life questionnaires, spirometry, serum immunoglobulin (IgE), peripheral eosinophil counts, and exhaled nitric oxide (NO) were obtained during study …

Life Expectancy And Years Of Life Lost In Chronic Obstructive Pulmonary Disease: Findings From The Nhanes Iii Follow-Up Study, Robert M. Shavelle, David R. Paculdo, Scott J. Kush, David M. Mannino, David J. Strauss

Rationale
Previous studies have demonstrated that chronic obstructive pulmonary disease (COPD) causes increased mortality in the general population. But life expectancy and the years of life lost have not been reported.
Objectives
To quantify mortality, examine how it varies with age, sex, and other risk factors, and determine how life expectancy is affected.
Methods
We constructed mortality models using the Third National Health and Nutrition Examination Survey, adjusting for age, sex, race, and major medical conditions. We used these to compute life expectancy and the years of life lost.
Measurements and main results
Pulmonary function testing classified patients as having …
The Effect Of Sex On Asthma Control From The National Asthma Survey, James Temprano, David M. Mannino
The Effect Of Sex On Asthma Control From The National Asthma Survey, James Temprano, David M. Mannino
David M. Mannino
Background Previous studies have demonstrated conflicting results with regard to differences in asthma control between the sexes.
Objective We sought to identify sex differences in short-term and long-term measures of asthma control in adults from the National Asthma Survey.
Methods This study analyzed data from the National Asthma Survey (Four-State sample) sponsored by the National Center for Environmental Health, Centers for Disease Control and Prevention. Asthma control was compared between the sexes based on short-term (recent symptoms, asthma attacks, and albuterol use) and long-term (asthma attacks, work days lost, and urgent-care visits and hospitalizations in the prior year) measures. Composite …
