Abstract

This study aimed to develop and refine an Athlete Food Choice Questionnaire (AFCQ) to determine the key factors influencing food choice in an international cohort of athletes. A questionnaire that contained 84 items on a 5-point frequency scale was developed for this study. Athletes at the 2017 Universiade in Taiwan were invited to participate. Principal component analysis (PCA) was utilised to identify key factors and refine the questionnaire. Completed questionnaires were received from 156 athletes from 31 countries and 17 sports. The PCA extracted 36 items organised into nine factors explaining 68.0% of variation. The nine factors were: 'nutritional attributes of the food', 'emotional influences', 'food and health awareness', 'influence of others', 'usual eating practices', 'weight control', 'food values and beliefs', 'sensory appeal' and 'performance'. The overall Kaiser-Meyer-Olkin was 0.75, Bartlett test of sphericity was statistically significant (X2 (666) =2536.50, p< 0.001) and all communalities remained >0.5. Intercorrelations were detected between 'performance' and both 'nutritional attributes of the food' and 'weight control'. Price of food, convenience and situational influences did not form part of the factorial structure. This research resulted in an AFCQ that includes factors specific to athletic performance and the sporting environment. The AFCQ will enable researchers and sports dietitians to better tailor nutrition education and dietary interventions to suit the individual or team. The next phase will test the accuracy and reliability of the AFCQ both during and outside of competition. The AFCQ is a useful tool to assist with management of performance nutrition for athletes.
