The prevalence and type of chronic obstructive bronchopulmonary disease in very old people.
One hundred men and 100 women between the ages of 70 and 89 years were examined clinically and with pulmonary function tests to determine the prevalence and type of chronic obstructive bronchopulmonary disease in very old people. Rhonchi were present in 45% of the old men and 24% of the old women. Obstruction to air flow (FEV(1) < 60% of FVC) was demonstrated in 23% of the men and 6% of the women. Chronic bronchitis was present in 32% and 12% of the old men and women, respectively. Only five individuals, all men, showed emphysema as defined by significant obstruction to air flow with a low diffusing capacity. In old people there was a relationship between smoking, chronic cough and obstruction to air flow.
