Disease risk factors associated with diet are often attributed to increased intake or lack of consumption of singular nutrients (e.g., saturated
fat, dietary fiber) or food groups (e.g., fruits and vegetables) [7]. However, including or excluding individual food items or food groups to or from the diet is difficult due to its complex nature. Because of these complex interactions, dietary habits are becoming increasingly characterized as latent variables or constructs. Latent variable analysis is the emerging standard of measuring dietary habits or “dietary patterns” using pattern identification protocols (i.e. find more cluster and factor analysis) [8]. Latent variable analysis has contributed to the understanding of dietary composition related to health outcomes [9], as healthful dietary patterns reduce risks for CVD markers [10]. Our purpose was to determine construct
validity of the nutrition component of the Rapid Eating and Activity Assessment for Patients (REAP) to describe dietary patterns of NCAA Division-I athletes using pattern identification protocol. Secondly, dietary pattern scores were examined in males and females between sport types, with the hypothesis that athletes in sports where success is SHP099 partially dependent on an amenable physique (e.g., gymnastics) exhibit different scores than athletes in sports where an appealing physique has no impact on success (e.g., baseball/softball). Lastly, we explored whether dietary pattern score was a predictor of CVD markers of body mass index (BMI) and waist circumference. Methods Data were obtained during two separate waves of collection, June-August 2011 (n = 150) and June-August 2012 (n = 241). In each wave, convenience samples of male and female NCAA Division-I athletes were asked to complete an informed consent and the REAP either immediately before or after a pre-participation physical examination. The protocol was approved by the University Office of Research Integrity and
Assurance. Demographic information was approved for extraction from the athlete’s electronic medical record (EMR) by the lead researcher and included sex, age, race/ethnicity, and selleck chemical sport. Data from the first wave (n = 150) of completed REAP surveys identified possible dietary patterns using principal components analysis (PCA). Data from the second wave (n = 241) confirmed dietary patterns using Doramapimod exploratory (EFA) and confirmatory (CFA) factor analysis. Mean differences in dietary pattern scores of athletes after stratifying by gender and the aesthetic nature of the sport were compared. The interactive role of dietary pattern score x aesthetic nature of the sport on markers of CVD (BMI and waist circumference) was examined within these subpopulations. Measurements The REAP was originally developed to evaluate the dietary behaviors with the goal to identify a comprehensive nutritional profile [11].
