Carefully standardized surveys of respiratory findings were conducted in the Plant Departments of five East Coast telephone companies during the period 1961-1969. The examination included the British Medical Research Council (MRC) questionnaire on respiratory symptoms. The study group comprised 1,849 men who were 40 through 64 years of age at examination. Illness absences of eight days or more were recorded from the time of examination until 1975, or until employment was terminated by retirement or death. The number of days lost from respiratory illnesses of eight days or more per 1,000 man-days at risk was calculated according to the responses to the major questions in the MRC questionnaire. The four questions indicating the highest risks were those pertaining to asthma, chronic wheeze, breathlessness and chest illnesses within the past three years.
