Abstract
The main objective of this study was to determine the feasibility and efficacy of a social media-based nutrition intervention using Twitter on nutrition knowledge, dietary practices, body mass index, self-efficacy, and social support among student-athletes. Participants included 50 male and female NCAA Division I student-athletes between the ages of 18-24 years old. Data were collected in October 2014. The study design employed a six-week, social media intervention using Twitter©, to increase nutrition knowledge, self-efficacy, social support and dietary adherence to the Dietary Guidelines for Americans recommendations. Descriptive statistics were calculated for all study variables and pre-post differences were assessed using paired t-tests. The results indicate a 6-week nutrition intervention delivered solely through social media resulted in increased nutrition knowledge (t=-2.23; p=0.035), reduced fat intake (t=- 1.57; p=0.13) and decreased BMI (t=2.32; p=0.027) in student athletes. In conclusion, social-media based nutrition education may provide university-based strength and conditioning coaches and other sports practitioners with a tool for widespread and timely access to students in order to facilitate healthy dietary behaviors.
