Tiivistelmä

Objective Low energy availability (LEA) is common in athletes. Disturbances in sex hormone levels due to insufficient energy availability have been suggested to influence cholesterol metabolism and impact the overall risk for cardiovascular disease. We assessed the relationship between Low Energy Availability in Females Questionnaire (LEAF-Q) and Eating Disorder Examination Questionnaire Short (EDE-QS) scores with cholesterol levels in a cross-sectional study of female athletes.

Method Finnish national- to international-level female athletes self-reported physiological symptoms of LEA, including menstrual disturbances, using the LEAF-Q (n=176) and eating disorder symptoms using the EDE-QS (n=294). Serum cholesterol concentrations (mmol/L) were determined from venous blood samples. We analysed the relationship between the different variables using Pearson's r and linear regression. We also studied separately participants representing lean sports, that is, sports that emphasise leanness (LEAF-Q, n=60; EDE-QS, n=80).

Results LEA symptoms were common; 72 (41%) of 176 participants scored >= 8 points in the LEAF-Q, which is indicative of a high risk of problematic LEA. A one-point increase in LEAF-Q score was associated with a small, non-significant increase in low-density lipoprotein (LDL) cholesterol level (beta=0.024, 95% CI -0.0011 to 0.049, p=0.061). Higher EDE-QS scores were associated with higher LDL cholesterol levels (beta=0.028, 95% CI 0.0098 to 0.046, p=0.0029). These associations were somewhat stronger among athletes representing lean sports (LEAF-Q and LDL: beta=0.043, 95% CI 0.0041 to 0.08, p=0.031; EDE-QS and LDL: beta=0.036, 95% CI 0.0041 to 0.068, p=0.028).

Conclusion In this study, LEAF-Q and EDE-QS were associated with higher LDL cholesterol levels among athletes representing lean sports.
