From the Department of Public Health, Division of Health Care Administration, University of Helsinki, Tüülüntullinkatu 8, SF-00250 Helsinki, Finland Longitudinal data on the effect of low tar cigarette smoking on respiratory symptoms was collected from a sample of Finnish young people born in 1966, by mailed questionnaires in 1979, 1983 and 1985. Cough was 3 to 6 times more common than expected after starting smoking low tar brands (1–10 mg tar). The increase in cough was the same as with those who started middle tar cigarette smoking (11–18 mg). Before starting smoking, the low tar cigarette smokers did not report more symptoms than the middle tar or nonsmokers. After a few years smoking cough and phlegm were 2 to 3 times more common in the low tar cigarette smokers than in the non-smokers but on the same level as in the middle tar cigarette smokers. Tar yield was not a significant predictor of symptoms in logistic regression analysis.
Key Words: low tar cigarette respiratory symptoms longitudinal study
