摘要

Objective: The objective was to explore eating behaviour, body image and energy status in female university team sport athletes. Design: This was a cross-sectional, descriptive study design. Setting: The setting was North-West University, Potchefstroom, South Africa. Subjects: Subjects were top university female field hockey and netball player volunteers, aged 18-30 years (n = 22), and recruited during their sport season. Outcome measures: Athletes completed demographic, health and sport, and body weight questionnaires. The Eating Disorder Inventory and the Three-Factor Eating Questionnaire's cognitive dietary restraint subscale were used to measure disordered eating behaviour. Body composition was measured with dual-energy X-ray absorptiometry. Estimated energy availability (est EA) was determined from a three-day diet and exercise record. Results: Fifteen (68) athletes were identified with an increased risk of disordered eating. Sixteen (73) were dieting. A low est EA (24 +/- 12 kcal/kg fat-free mass/day) was found in 59 of the athletes, of whom 85 (11/13) had increased risk of disordered eating. A significantly positive (p-value < 0.05) association was found between cognitive dietary restraint and drive for thinness (r = 0.4) and body weight (r = 0.5). A negative association was found between desired weight loss (r = -0.5), energy intake (r = -0.5) and (est)EA (r = -0.7). Conclusion: Nonlean build athletes who diet in season are at increased risk of disordered eating behaviour and low energy availability.
