Abstract
The increasing prevalence of adolescent smoking demonstrates the need to id entify factors associated with early smoking initiation. Previous studies h ave shown that smoking by social network members and receptivity to pro-tob acco marketing are associated with smoking among adolescents. It is not cle ar, however, whether these variables also are associated with the age of sm oking initiation. Using data from 10,030 California adolescents, this study identified significant correlates of age of smoking initiation using bivar iate methods and a multivariate proportional hazards model. Age of smoking initiation was earlier among those adolescents whose friends, siblings, or parents were smokers, and among those adolescents who had a favorite tobacc o advertisement, had received tobacco promotional items, or would be willin g to use tobacco promotional items. Results suggest that the smoking behavi or of social network members and pro-tobacco media influences are important determinants of age of smoking initiation. Because early smoking initiatio n is associated with higher levels of addiction in adulthood, tobacco contr ol programs should attempt to counter these influences. (C) 1999 Elsevier S cience Ltd.
