Effects of tobacco-related media campaigns on smoking among 20–30-year-old adults: longitudinal data from the USA
Cette étude longitudinale américaine analyse l'impact d'une campagne médiatique relative aux effets du tabac sur les comportements tabagiques des adultes agés de 20 à 30 ans
Objective Young adults in the USA have one of the highest smoking prevalence rates of any age group, and young adulthood is a critical time period of targeting by the tobacco industry. The authors examined relationships between potential exposure to tobacco-related media campaigns from a variety of sponsors and 2-year smoking change measures among a longitudinal sample of US adults aged 20–30 years from 2001 to 2008.Methods Self-report data were collected from a longitudinal sample of 12 931 US young adults from age 20 to 30. These data were merged with tobacco-related advertising exposure data from Nielsen Media Research. Two-year measures of change in smoking were regressed on advertising exposures.Results Two-year smoking uptake was unrelated to advertising exposure. The odds of quitting among all smokers and reduction among daily smokers in the 2 years between the prior and current survey were positively related to anti-tobacco advertising, especially potential exposure levels of 104–155 ads over the past 24 months. Tobacco company advertising (including corporate image and anti-smoking) and pharmaceutical industry advertising were unrelated to quitting or reduction.Conclusion Continued support for sustained, public health-based well-funded anti-tobacco media campaigns may help reduce tobacco use among young adults.
