The Surabaya youth survey used amodified version of the Global Youth Tobacco Surveyquestionnaire to investigate knowledge, attitudes andpractices concerning smoking among 1,630 students in 40 highschools in Madiun City, Malang City, Jember Regency andBangkalan Regency in 2003. Factors which predispose, enable,and reinforce smoking were examined to identify wheretobacco control interventions might be appropriate andeffective. Female students showed an unexpectedly highsmoking rate. Students were aware of the health risksassociated with smoking but underestimated how addictivecigarettes are. Generally, they found cigarettes affordableand accessible, but those who perceived cigarettes not veryeasy to obtain smoked less. Schools appeared to besmoker-friendly environments. Students who lived inhouseholds with smokers were more likely to smoke, butparental disapproval of smoking was associated with a lowersmoking rate. Smokers, in particular, affirm many social andpersonal reasons to smoke. These findings suggest manypossibilities for interventions.
