Abstract
The aim of this study was to investigate the influence of peer and family influences on tobacco use onset among Italian early adolescents at two-year follow-up. Participants were 161 adolescents aged 11 to 12 (M = 11.14, SD = 0.39; 49% female) living in the northwest of Italy. Multiple logistic regressions were used. Results indicated that increases in positive family climate were negatively associated with lifetime smoking among non-smokers at two-year follow-up. Additionally, parental knowledge of child daily activities decreased lifetime smoking at two-year follow-up. Moderation analyses revealed that parental knowledge reduced the effect of peers' influence on youth smoking onset at two-year follow-up. This study underlined the influence of parenting practices in preventing early smoking initiation in Italy.
