Abstract (Summary)

Low energy availability (LEA) can detrimentally affect an athlete’s metabolic rate, bone health, and the reproductive health of female athletes. Screening tools to identify athletes at risk for LEA are needed. However, dietary recall methods such as the RD-administered 24-hour recall are burdensome for both registered dietitians and athletes.

The purpose of this study is to evaluate the concurrent validity of a web-based nutrition screening survey (NSS) meant to facilitate the efficient evaluation of food intake and nutritional risk, against a registered dietitian-administered 24-hour recall among male and female collegiate endurance runners. Participants attended a meeting with their sports dietitian, at which point an initial RD-administered 24-hour recall was collected. After a washout period of two weeks, athletes were prompted to complete the NSS. Correlations and means tests were used to compare energy and macronutrient intakes.

A total of 46 collegiate endurance runners were included in the final analysis. Based on the correlation analysis, the NSS and RD-administered recall displayed significant association for energy (r= .565, p < .001), fat (r = .535, p < .001), and protein intake (r= .414, p < .01), when outliers were excluded. There were no significant differences in average intake, for each nutrient assessed, between recall methods, indicating agreement at the group level. Bland-Altman Plot Analysis displayed proportional bias in energy intake between recall methods. This study suggests agreement between NSS and the RD-administered 24-hour recall, particularly for group data.
