A survey of the prevalence of chronic nonspecific respiratory disease in the residents of Berlin, New Hampshire, was conducted. The survey conducted in 1967, was a followup to a similar survey conducted in 1961. The cohort consisted of 1,528 residents, 829 females, ranging in age from 25 to 74+ years. The subjects completed a questionnaire to obtain information on respiratory health and smoking habits. Pulmonary function tests were administered. Air quality was monitored by measuring soluble and insoluble dustfall and lead-peroxide (1309600) at eight monitoring stations. The concentrations of lead-peroxide and soluble and insoluble dust were less than in 1967; the largest decrease occurred in the concentration of lead-peroxide. No consistent pattern in the prevalence of reported respiratory symptoms in 1967 relative to 1961 was seen. For example, the occurrence of phlegm was less in males but more in females. The prevalence of chest colds was less in males in 1967 but unchanged in the female subjects. Males reported a decrease in intensity of their smoking in 1967 compared to 1961, whereas females smoked at about the same intensity. When stratified by smoking status, the prevalence of all chronic respiratory disease was slightly less in 1967 than in 1961. The observed values of forced vital capacity and peak expiratory flow were generally higher than the values predicted from the 1961 data, especially in the males. The authors suggest that decreases in air pollution between 1961 and 1967 may have resulted in the decreased prevalence of chronic respiratory disease and slight improvement in pulmonary function observed in 1967.
