On November 24, 2018, at the Department of Epidemiology, Biostatistics and Evidence-Based Medicine of the Faculty of Medicine and Healthcare of the Kazakh National University named after Al-Farabi, the long-awaited meeting of the scientific club “Journal Club” took place. Analysis of scientific articles is the most important part of the work of scientists. Reading the articles of other authors, you can find new topics or be inspired by ideas for writing your own article. During the meeting of the Journal Club there were interesting discussions. After presenting the main results of a systematic review of the effectiveness of social networks to change behavioral factors affecting people's health, the speaker (undergraduate of the scientific and pedagogical direction of the 2nd course Esimbekova G.), among those present, who also had students from other universities, discussed and disadvantages of both the publication itself, the study, and the effectiveness of the influence of social networks as a method of mass change in the behavior of people. Our traditional experts are Associate Professor of the Department of Epidemiology, Biostatistics and Evidence-Based Medicine, Faculty of Medicine and Health, Al-Farabi Kazakh National University, Head of the Health and Environmental Research Laboratory, Ph.D. Vinnikov D.V. and Director of the KSPH Faculty of Medicine and Healthcare of the Kazakh National University named after Al-Farabi, Ph.D. Oshibayeva A.E. helped participants fully understand the interpretation of the results of a systematic review. The presented systematic review was conducted in eight databases and covered scientific publications from 2000 to 2012. According to the results of the discussion of the study, the participants came to the conclusion that today, in the era of the development of computer technology, when there is a possibility of mass influence on the younger generation through popular social networks, traditional methods of informing are mainly used. The use of online interventions has both advantages and disadvantages. We thank all the guests who came to actively participate in the " Journal Club ".
