摘要:This study is the first to provide complete information on prevalence rates by gender and geographic variation for each type of tobacco product used in the United States. Results indicate that, in nearly half of all states, total tobacco use in men exceeded 40% and, in four states, exceeded 50%. In women, only Nevada, Kentucky, and Michigan reported prevalence exceeding 33%. Results also indicate, however, that concurrent use of multiple tobacco forms is relatively rare. Substantial regional variation in male total tobacco use was evident, with southern males exhibiting the highest prevalence rate (44.6%). As a result, this region represents a target group in special need of comprehensive and effective tobacco use interventions.
