Though components of the Female Athlete Triad were redefined, disordered eating patterns still pose a risk to energy status and health of female adolescent athletes. This cross-sectional study assessed the association between cognitive dietary restraint and energy availability, macro- and micronutrient intakes, food group intake, menstrual function, and bone density in female adolescent endurance runners (n=41, age 15.71 + 1.08 y). Independent-sample t-tests examined significant differences between those with elevated and non-elevated restraint. ANCOVA tested for significant differences in bone density between groups controlling for BMI. Linear regression examined relationships between restraint and diet intakes. Those with elevated restraint had significantly higher body weight (p=0.049), higher resting metabolic rate (p=0.042), higher daily energy expenditure (p=0.047), higher fiber intake (p=0.017), lower daily servings of grains (p=0.011), higher daily servings of fruits (p=0.005), and lower lumbar spine z-scores (p=0.032). Lumbar spine z-scores remained significantly lower after controlling for BMI (p=0.01). Restraint subscale score significantly predicted relative intakes of calories, carbohydrate, fiber, fat and daily servings of grains, fruits, vegetables, and sweets. These findings suggest there is an association between cognitive dietary restraint and certain measures of diet intake and Female Athlete Triad-related health in female adolescent endurance runners.
