NCT00005425
To determine the effects in early adulthood of asthma, increased bronchial responsiveness, markers of allergy and smoking on pulmonary function level and the effects of these same risk factors on subsequent decline in pulmonary function, because these early adult factors presumably profoundly influence the risk for chronic obstructive pulmonary disease.
NCT00005281
To continue to evaluate risk factors heretofore determined to be important predictors of chronic respiratory symptoms, diagnosis of asthma, and alterations in expected levels of lung function in children and adolescents in a new population of young adult women.
NCT00005537
To perform a genome-wide search for genes affecting two phenotypes related to asthma and chronic obstructive pulmonary disease (COPD) in a Chinese population.
NCT00005284
To prospectively identify factors that influence the rate of decline in pulmonary function and to identify predictors of chronic obstructive lung disease (COLD) and asthma in a population sample of older adults.
NCT01698151
This is an observational study in primary care aiming to validate biomarkers for chronic obstructive pulmonary disease (COPD).
