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.
The questions studied included whether the above named risk factors reduced the maximally attained level of pulmonary function in early adulthood, foreshortened the postulated stability of level of pulmonary function between age 18 and 35 and/or unfavorably affected subsequent decline in level of pulmonary function. FEV1/h2, VC/h2 and FEV1/IVC were studied, using graphic smooth techniques and regression analyses techniques on both cross-sectional and longitudinal datasets. In addition, the investigators tested the hypothesis stating that early adult symptoms of asthma, increased bronchial responsiveness, markers of allergy influenced who became a smoker, influenced the amount smoked and/or influenced who stopped smoking relatively early in adult life, using logistic regression analyses and survival analyses.

Asthma attacks caused, triggered, or exacerbated by OCCUPATIONAL EXPOSURE.
Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).
Drugs that are used to treat asthma.
A beta-adrenergic agonist used in the treatment of asthma and bronchospasms.
Adrenergic beta-2 agonist used as bronchodilator for emphysema, bronchitis and asthma.
Asthma is caused by inflammation of small tubes, called bronchi, which carry air in and out of the lungs. If you have asthma, the bronchi will be inflamed and more sensitive than normal. When you come into contact with something that irritates your...
The term allergy is used to describe a response, within the body, to a substance, which is not necessarily harmful in itself, but results in an immune response and a reaction that causes symptoms and disease in a predisposed person, which in turn can cau...
