RESUMO
Smoking and alcohol intake patterns may persist from adolescence to adulthood. The aims of this study are to determine the prevalence and factors associated with smoking and drinking habits among Form Six students. This was a cross-sectional study conducted in January 2003 among Form Six students from government schools in the Petaling District, Selangor. A hundred and thirty six self-administered questionnaires were distributed to students selected through multistage stratified sampling. Response rate in this study was 90.1% (136/151). The respondents were mainly Chinese 60 (44.1%) and female 88 (64.7%). The prevalence of smoking was 22.8%, whereas the prevalence of alcohol intake was 47.8%. Only 33.1% of the respondents practiced undetermined activities and 1.5% have undetermined characters. There were significant associations between smoking and males (Adjusted OR 2.56, 95% CI 1.02-6.43) and smoking and alcohol intake (Adjusted OR 2.74, 95% CI 1.11-6.78). Alcohol intake has significant negative association with Malays (Adjusted OR 0.83, 95% CI 0.03-0.27). Smoking habits among adolescents were associated with males and alcohol intake. However, only alcohol intake was negatively associated with Malays. Program interventions to reduce behavioral problems, particularly smoking and alcohol intake should be emphasized.
