Using Online Respondent Driven Sampling for Vietnamese Youths' Alcohol Use and Associated Risk Factors / 대한의료정보학회지

OBJECTIVES: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. METHODS: An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. RESULTS: About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. CONCLUSIONS: A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.

A Short Course in Advanced Medical Teaching for Talented Hanoi Medical University Graduates.

The Australian Vietnam Medical Foundation of the University of Sydney, in collaboration with Hanoi Medical University (HMU), conducted an Advanced Course in Medical Teaching for talented recent graduates who are expected to become leaders in clinical and academic medicine in Vietnam. The intention was to deliver a part-time course taught in English which would expand their medical horizons, increase their clinical skills and help them modernize their teaching within the HMU curriculum, particularly in specifying undergraduate learning objectives and developing clinical assessment. We report on the aims, content and conduct of the first instalment of the course in Hanoi in 2010-2011.
