Filter by: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.
The overall objective of the Center was to develop a scientific data base for the control and prevention of acute and chronic lung injury caused by the inhalation of a variety of agents in the workplace and in the environment. There were two epidemiologic studies. Respiratory Effects of Exposures to Irritant Gases: To collect longitudinal lung function and symptom data in chemical manufacturing workers who were exposed to chemical irritants such as ammonia, chlorine, phosgene, isocyanates, sulphur dioxide, nitrous oxide, formaldehyde, organic acids, hydrochloric acid fluorides, other aldehydes, and acid anhydrides. Workers in the Cotton Textile Industry: To detect and quantitate the risk for the development of chronic obstructive airways disease which occurred in workers exposed to cotton dust in textile manufacturing.
To determine the natural history, etiology, and interrelationships of emphysema, chronic bronchitis, asthma, and related airways obstructive diseases. Also, to determine the relationship of acute lower respiratory tract illnesses in infants and children to the development of subsequent chronic lung disorders.
To test specific hypotheses concerning environmental, occupational, lifestyle, and other risk factors for sarcoidosis. Also, to examine the familial aggregation of sarcoidosis and to test genetic hypotheses concerning its etiology. Finally, to describe the natural history of sarcoidosis, particularly in African-Americans who appear to be disproportionately affected, and to implement a system for storing biological specimens including blood cells, plasma, and serum.
To test whether sleep-disordered breathing is associated with an increased risk of coronary heart disease, stroke, all-cause mortality, and hypertension. The multicenter, longitudinal study draws on existing, well-characterized, and established epidemiologic cohorts.
To determine the prevalence and natural history of pulmonary and cardiac complications associated with HIV infection in utero, in infancy, and during early childhood.
To evaluate the types, incidence, course, and outcome of pulmonary disorders in newly diagnosed cases of Acquired Immune Deficiency Syndrome (AIDS), newly diagnosed cases of AIDS-related complex (ARC) and newly diagnosed asymptomatic human immunodeficiency virus (HIV) infection.
To determine the effects of long-term exposure to passive smoking on the cardiovascular and oxygen transport systems in pre-adolescent twins.
To define new national norms for pediatric blood pressure by adjusting the available data set of over 60,000 pediatric blood pressure readings for age, height and gender among children of normal body weight.
To supplement the fourth National Health and Nutrition Examination Survey protocol to include data on the common heart, vascular, lung, and blood diseases.
