[BDSP. Notice produite par INIST hHv90R0x. Diffusion soumise à autorisation]. Context. - Adolescent smoking prevalence is tracked annually and has increased since 1991. In contrast, little is known about trends in smoking among college students, a group that has previously been more resistant to tobacco use than other young adults. Objective. - To examine changes in cigarette smoking among college students between 1993 and 1997 and among different types of students and colleges. Design. - Self-administered survey (Harvard School of Public Health College Alcohol Study). Setting. - One hundred sixteen nationally representative 4-year colleges. Subjects. - A total of 15 103 randomly selected students in 1993 (70% response rate) and 14251 students in 1997 (60% response rate). Main Outcome Measures. Self-reports of cigarette smoking in the past 30 days and in the past year, age at smoking first cigarette, and number of attempts to quit. Results. - Over 4 years, the prevalence of current (30-day) cigarette smoking rose by 27.8%, from 22.3% to 28.5% (P<. 001). The increase was observed in 99 of 116 colleges and was statistically significant (P<. 05) in 27 (23%) of them. Current smoking increased across all student subgroups (defined by sex, race/ethnicity, and year in school) and in all types of colleges. Smoking is rising faster in public schools (from 22.0% to 29.3%) than in private schools (from 22.9% to 26.8%). (...)
