Comparison of smoking prevalence in school students sampled from the United States of America and the Union of Soviet Socialist Republics.

To assess the smoking prevalence among adolescents in the USA and the USSR, students in Moscow and Minneapolis were surveyed by common protocol and identically trained staff. Smoking habits were measured by a self-report questionnaire and an expired air sample of carbon monoxide (CO). Significant gender differences were found between the two national groups. Among girls in the USA, there was a significantly higher rate of weekly smoking as compared to girls in the USSR. Among boys in the USSR as compared to those in the USA, there was a significantly higher rate of ever smokers and daily smokers, but also of ex-smokers. These gender differences may reflect cultural differences in smoking patterns between the two countries. Cigarette smoking is clearly a public health problem in both countries with its onset in adolescence.
