The consumption of nutritional supplements is high in various sports, whereas, there are not enough documents supporting the beneficial effects of supplements in athletes. In addition, there is no information about taking supplements by Iranian students who participate in sports. Therefore, the goals of this study were to assess the type and prevalence of supplement use, the frequency of use, and relationships between consumption and age, body mass index, training load and type of sport.
One hundred ninety two male students from "Isfahan University of Medical Sciences" participated in this study, voluntarily. A questionnaire that included questions about type and effects of supplements, recommendation resources, place of obtaining, and type of sports were sent to students. Descriptive data were calculated as frequencies (%). Chi-square (χ2) analysis was used to analyze the correlation between supplement use and the study variables.
Forty-five percent of respondents used some forms of supplements. Supplement users consumed 14 different supplements and each used as many as 1.8 ± 1.2 various supplements during the past six months. Multivitamins (64%) and vitamin C (42%) were the most popular supplements. Students, who participated in individual sports, were more likely to consume dietary supplements (P < 0.05) and ergogenic aids (P < 0.01), but team sports athletes, took more recovery nutrients (P < 0.01). Fifty seven point five percent of student bought their products from pharmacies, 40% from "sport supplements stores" and 2.5% from their friends.
It can be concluded that less than half of these students consumed supplements and their information resources were inappropriate.
在各类体育运动中，营养补充剂的使用颇为普遍，然而，尚无充分文献支持补充剂对运动员有益。此外，对于参与体育运动的伊朗学生使用补充剂的情况也缺乏相关信息。因此，本研究的目的是评估补充剂使用的类型和流行程度、使用频率，以及补充剂消费与年龄、体重指数、训练负荷和运动类型之间的关系。
来自“伊斯法罕医科大学”的192名男学生自愿参与了本研究。向学生发放了一份问卷，其中包括关于补充剂类型和效果、推荐资源、获取地点以及运动类型等问题。描述性数据以频率（%）计算。采用卡方（χ2）分析来分析补充剂使用与研究变量之间的相关性。
45%的受访者使用了某种形式的补充剂。补充剂使用者消费了14种不同的补充剂，在过去六个月中，每人使用的各类补充剂多达1.8±1.2种。多种维生素（64%）和维生素C（42%）是最受欢迎的补充剂。参加个人运动的学生更有可能食用膳食补充剂（P<0.05）和促力剂（P<0.01），但团队运动运动员摄入的恢复性营养物质更多（P<0.01）。57.5%的学生从药店购买产品，40%从“运动补充剂商店”购买，2.5%从朋友处获得。
可以得出结论，这些学生中不到一半的人使用补充剂，且他们的信息来源并不恰当。
