A review of studies focused on determinants of adolescents' smoking behaviour (ASB) published between 1990-2000 is presented. Determinants were divided into three groups: individual factors, social factors and societal factors. Individual factors include knowledge, intentions, attitudes, health-related behaviour, personality characteristics and school-related variables. Social factors include smoking behaviour of parents, siblings, peers and significant adults, but also family characteristics, social support, and socio-economic status. Societal factors include restrictions on smoking, tobacco advertisement, and smoking behaviour of adolescents' role model.
