RESUMEN
BACKGROUND: Little is known about the supplements use and recreational sport practices in Kazakhstan university students. Therefore, the aim of this study was to ascertain supplements use prevalence and their predictors in this population. METHODS: Cross-sectional survey of both undergraduate and graduate level students was completed in 2017 et al.-Farabi Kazakh National University, the largest higher institution in the country, from almost all Schools. A 45-item questionnaire was used to record physical activity, supplements use, lifestyle attributes (smoking, alcohol, sleep, etc.) and eating habits, and adjusted regression models were used to verify predictors of supplements use. RESULTS: Of the entire sample of 889 students (70% females), 526 (59%) were practicing recreational physical activity (RPA), and walking, jogging and track and field was the most popular activity type (38%). N = 151 (29%) students reported the use of any supplement (31% in men and 27% in women), whereas the most popular supplement type were vitamins. Supplement use was most prevalent in swimmers (55%). Age (odds ratio (OR) 1.19 (95% confidence interval (CI) 1.04-1.37), use of fitness tracker (OR 6.26 (95% CI 3.90-10.03)) and low-fat diet (OR 1.95 (95% CI 1.23-3.10)), but not income predicted supplements use in adjusted models. CONCLUSIONS: With more than half of students exercising regularly, only less than one-third use supplements with a very strong association with fitness tracker use.
