Use of the productive cough test to confirm presence of respiratory symptoms in school-age children.
We assessed the prevalence of respiratory symptoms and loose cough in 622 school-age children from an urban town in Connecticut. A higher prevalence of chronic symptoms was reported by black children, but the prevalence of recent symptoms and of loose cough in black children was similar to that in white children. The relationship between prevalence of recent symptoms and loose cough suggests that the observed racial differences in prevalence of chronic symptoms were unlikely to be due to racial differences in responses to a respiratory symptom questionnaire.
