Information on current-, never- and ex-smokers (including duration of cessation) was obtained in a cross-sectional survey of risk factors for coronary heart disease (CHD), the Scottish Heart Health Study. Diet was also assessed by food frequency questionnaire in a total of 4265 men and 4770 women. Nutrient intakes were computed by sex and smoking group and, according to their diet, the ex-smoke...
Many studies reviewed show that both workplace exposure to organic dust and smoking may cause chronic respiratory symptoms and airflow limitation in susceptible subjects. We performed a case-control study including 63 tea workers (36 male and 27 female, aged 36-55, duration of employment 3–30 years) and an equal number of office workers, matched by sex and age. Chronic respiratory symptoms (chr...

DESIGN Before-after comparison in 2 academic hospitals with parallel comparisons in 2 control hospitals. SETTING Academic hospitals in Switzerland. PARTICIPANTS Smokers hospitalised for an acute coronary syndrome (ACS)....

We took advantage of data pooled in the International Head and Neck Cancer Epidemiology Consortium to evaluate the role of involuntary smoking in head and neck carcinogenesi...

STUDY DESIGN Ten-year, eight-wave prospective cohort study of a state-wide community sample in Victoria, Australia. METHODS Partic...
The effect of smoking five non-nicotine cigarettes and of breathing carbon monoxide on exercise-induced angina was evaluated in 12 patients with angina. Smoking increased venous carboxyhemoglobin from 1.71 to 5.35%, decreased exercise duration until angina 45%, increased ischemic STsegment depression at angina from 1.33 to 1.52 mm, and decreased systolic blood pressure times heart rate at angin...
