In a cross-sectional study of 2,112 Norwegian army conscripts ages 18
to 25, the prevalence of daily smoking was 50.9%. Among the smokers, 5
5.7% had increased smoking during military service, and 7.8% of the no
nsmokers had started to smoke. These changes in smoking behavior were
correlated with having a best friend who smoked, with dissatisfaction
with the military service, with physical inactivity, and with frequent
alcohol consumption. Ninety percent lived in dormitories where cigare
tte smoking occurred regularly. Attitudes toward smoking restrictions
were determined mainly by the subjects' smoking behavior and subjectiv
e discomfort caused by cigarette smoke. Smokers as well as nonsmokers
having a best friend who smoked were significantly less bothered by ci
garette smoke than others. The findings support the conclusion that mi
litary service has a negative influence on the smoking behavior of you
ng Norwegian men. Intervention strategies are recommended. (C) 1994 Ac
