Objective To investigate the alcohol drinking among high school students， determine the possible influencing factors， and provide scientific evidence for effective control of alcohol drinking among high school students.
Methods This study adopted stratified cluster sampling and included 4 high schools in Changning District （including one vocational high school）. Self-designed questionnaires were used to investigate alcohol drinking related knowledge and behavior among high school students. The questionnaire included demographics， alcohol drinking frequency and scenarios. SPSS 20.0 was used for Chi-square test and multivariate logistic regression analysis.
Results There were 811 high school students included in this study. The proportion of ever alcohol drinking was determined to be 48.09% （n=390） among students. Furthermore， 36.13% （n=293） reported alcohol drinking in the past year， and 14.80% （n=120） reported drinking in the past month. The proportion of excessive alcohol drinking was 8.26% （n=67） and that of alcohol dependence was 3.58% （n=29）. Moreover， the proportion of Chinese Baijiu （Chinese liquor） drinking in the past month was significantly higher than that in the past year （P<0.05）. In contrast， the proportions of wine and rice wine drinking in the past month was significantly lower than those in the past year （P<0.05）. The logistic regression model suggested no alcohol drinking in the past 30 days， parents disagreeing to their children’s drinking， some of friends having alcohol drinking， higher frequency of attending friend gatherings， and smoking were significantly associated with alcohol drinking among the students.
Conclusion Alcohol drinking is moderately prevalent among high school students. Possible influencing factors may be correlated to their parents and friends. It warrants targeted intervention measures to prevent and control the early alcohol drinking among adolescents to avert alcohol dependence.
