“…Factors related to cigarette smoking among adolescents from previous studies conducted in various countries can be organized into four categories. First, personal characteristics, consisting of sex (Chung & Joung, ; Sylvestre, Wellman, O'Loughlin, Dugas, & O'Loughlin, ; Wellman et al, ), grade (Wellman et al, ), and use of other tobacco products (Harrell, Naqvi, Plunk, Ji, & Martins, ; O'Loughlin et al, ); second, the family environment, including parental smoking (Choi, Kim, Lee, Kashiwabara, & Oh, ; Mays et al, ) and SHS in home (O'Loughlin et al, ; Wellman et al, ); third, friends and social contexts, including myths that smoking is good for socializing (Cable, Roman Mella, & Kelly, ) and susceptibility to smoking (El‐Toukhy, Sabado, & Choi, ; Lee, Lee, & Lee, ; Sylvestre et al, ); and fourth, the school and general public environments, including SHS in indoor locations (Sylvestre et al, ), SHS on school property (Wellman et al, ), and exposure to antitobacco advertisements (Wellman et al, ). However, though these studies revealed several factors related to adolescent cigarette smoking, the knowledge gained was somewhat limited, as most were conducted in only one country.…”
