The aim of this study was to analyze the association between substance use  and body mass index (BMI) among adolescents in Southern Taiwan.
A total of  10,259 adolescent students aged 11–19 years were selected by stratified random  sampling for proportional representation of districts, schools and grades in  Southern Taiwan, and completed the questionnaires. The body weight, body height,  experience of substance use and sociodemographic characteristics including sex,  age, residential background and paternal/maternal educational levels were  collected. The association between substance use and BMI, and the moderating  effects of sociodemographic characteristics were examined.
After adjusting for  sociodemographic characteristics, BMI was higher for adolescents who smoke  cigarettes or drink alcohol than for those who do not regularly smoke or drink.  Chewing betel nuts and using illicit drugs were not significantly associated  with BMI. Paternal education level had a moderating effect on the association  between smoking and BMI. Smoking, alcohol drinking, and low paternal education  level were associated with higher BMI among adolescents.
Thus, healthcare professionals should pay more attention to the weight-related problems among these adolescents.
