Filter by:This 31-month supplement to Sustaining Women's Smoking Cessation Postpartum (Project PANDA) designed, implemented, and evaluated an intensified intervention for pregnant women who were unable to stop smoking with minimal assistance.
To perform a genome-wide search for genes affecting two phenotypes related to asthma and chronic obstructive pulmonary disease (COPD) in a Chinese population.
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.
To provide information necessary for the development of standards for peak expiratory flow (PEF) test performance in populations studies.
To conduct a longitudinal study of the relationship between the rate of decline of pulmonary function and measurements of cortisol concentration and excretion in a sample of middle-aged and older men and their wives. The study tested the hypothesis that persons whose plasma cortisol concentrations were relatively low, albeit within the normal range, were predisposed to excessively rapid deterioration of pulmonary function during aging.
To collect data from the 37 participating clinical centers on patients with alpha1-antitrypsin deficiency, including those who received replacement therapy with an intravenous preparation of alpha1-proteinase inhibitor (A1Pi) concentrate.
To characterize the nature of pulmonary responses to organic dust exposures in order to gain insight into patterns of respiratory disease in agricultural workers.
To determine factors, including maternal cigarette smoking and acute respiratory illness, influencing infant lung function at birth and up to five years of age.
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.
From 1981 to 1991, to characterize the role of allergy and airways responsiveness in modifying growth of lung function in children and young adults in a community-based random population, the Childhood Respiratory Study in East Boston. From 1992 to 1997, to examine the relationship of respiratory symptoms and illnesses, cigarette smoking, airways responsiveness, and markers of inflammation to growth and decline in lung function in two well-characterized and investigated community-based populations of children and adults, the Childhood Respiratory Study in East Boston and the Normative Aging Study.
