[BDSP. Notice produite par INIST sIR0x3cQ. Diffusion soumise à autorisation]. Context Recent marked increases in adolescent smoking indicate a need for new prevention approaches. Whether workplace and home smoking restrictions play a role in such prevention is unknown. Objective To assess the association between workplace and home smoking restrictions and adolescent smoking. Design, Setting, and Subjects Data were analyzed from 2 large national population-based surveys, the Current Population Surveys of 1992-1993 and 1995-1996, which included 17185 adolescents aged 15 to 17 years. Main Outcome Measures Smoking status of the adolescents surveyed, compared by presence of home and workplace smoking restrictions. Results After adjusting for demographics and other smokers in the household, adolescents who lived in smoke-free households were 74% (95% confidence interval [Cl], 62% - 88%) as likely to be smokers as adolescents who lived in households with no smoking restrictions. Similarly, adolescents who worked in smoke-free workplaces were 68% (95% CI, 51% - 90%) as likely to be smokers as adolescents who worked in a workplace with no smoking restrictions. Adolescent smokers were 1.80 (95% Cl, 1.23-2.65) times more likely to be former smokers if they lived in smoke-free homes. The most marked relationship of home smoking restrictions to current adolescent smoking occurred in households where all other members were never-smokers. (...)
