Identify the reason why these tests are used by explaining the type of data variables under study (Independent and Dependent Variables). The objective is to identify the relationships between energy drink consumption, nutrition knowledge, and socio-demographic characteristics in a convenience sample of student-athletes. Design Cross-sectional. Setting Online survey. A total of 194 student-athletes (112 female and 82 male) participated. Main Outcome Measures Socio-demographic characteristics, knowledge of human nutrition, energy drink consumption habits. Analysis Chi-square tests of independence, independent t tests, and hierarchical regression analyses were applied. The results were most student-athletes in the sample (85.5%) did not consume energy drinks, but those who did tended to be male ( P = .004), had lower overall knowledge of nutrition ( P = .02), and had a lower grade point average ( P < .001) than did nonusers. Also, energy drink consumption was associated with the overall nutrition knowledge score when adjusted for socio-demographic characteristics, with nonusers having greater nutrition knowledge ( P = .007) than users.In Conclusion, student-athletes tend to refrain from energy drink use but those who use it have a tendency to have lower nutrition knowledge than do nonusers. Therefore, nutrition education targeted toward student-athletes should encompass the consumption
