This study, published in Tobacco Control, adds to the mountain of evidence about the health risks of smoking.
Objectives: To determine the risk in men and women smoking 1–4 cigarettes per day of dying from specified smoking related diseases and from any cause.
Design: Prospective study.
Setting: Oslo city and three counties in Norway.
Participants: 23,521 men and 19,201 women, aged 35–49 years, screened for cardiovascular disease risk factors in the mid 1970s and followed throughout 2002.
Conclusions: In both sexes, smoking 1–4 cigarettes per day was associated with a significantly higher risk of dying from ischaemic heart disease and from all causes, and from lung cancer in women. Smoking control policymakers and health educators should emphasise more strongly that light smokers also endanger their health.
