Drinking Behavior and Associated Factors among Middle School Students in Shanghai, China.

The purpose of our study was to assess drinking status in middle school students and to understand the associated factors. The adjusted drinking rates were 50.9%, 39.8%, and 15.1% for lifetime, past-year, and current drinking, respectively. Multivariable logistic regression revealed the following variables positively related to drinking during the past year: family income, maternal educational level, family members who drink, parents who support drinking, best friends who drink, friends who encourage drinking, frequently attending friends' parties, smoking, and actuation trend (P<0.05). The main risk factors were friends (OR=6.77, 95% CI: 6.17, 7.43) and smoking (OR=4.70, 95% CI: 3.44, 6.43). These results contribute to obtaining the potential associated factors and aid in targeted intervention into the drinking behavior of middle school students.
