In conclusion, numerous studies have investigated the influences of movie smoking or peer
influence on adolescents’ smoking behaviour, and a few have considered the differences
among ethnic/social groups. Although small, to our knowledge, our study is unique in finding
an important combined effect of movie smoking and peer influence in a context of ethnicity.
With more extensive further research, understanding such issues sensitive to cultural
differences and social behaviours in a given population could be useful information when
designed targeted social marketing strategies for behaviour change.
