Asthma is a multifactorial lung disease that causes wheezing, shortness
of breath, coughing, and chest tightness. It is often associated with familial,
allergenic, socioeconomic, psychological, and environmental factors.6,7 Asthma affects proportionately more children than adults, women
than men, and nonwhites than whites.1 Morbidity and mortality can
be partly preventable with better medical, environmental, and self management.
