Prevalence of Female and Male Athlete Triad Risk Factors in Ultramarathon Runners.
Prevalence of Female and Male Athlete Triad Risk Factors in Ultramarathon Runners. Clinical journal of sport medicine : official journal of the Canadian Academy of Sport Medicine Hoeg, T. B., Olson, E. M., Skaggs, K., Sainani, K., Fredericson, M., Roche, M., Kraus, E. 2021Abstract
OBJECTIVE: To identify the prevalence of male and female athlete triad risk factors in ultramarathon runners and explore associations between sex hormones and bone mineral density (BMD).DESIGN: Multiyear cross-sectional study.SETTING: One hundred-mile ultramarathon.PARTICIPANTS: Competing runners were recruited in 2018 and 2019.ASSESSMENT OF RISK FACTORS: Participants completed a survey assessing eating behaviors, menstrual history, and injury history; dual-energy x-ray absorptiometry for BMD; and laboratory evaluation of sex hormones, vitamin D, and ferritin (2019 cohort only).MAIN OUTCOME MEASURE: A Triad Cumulative Risk Assessment Score was calculated for each participant.RESULTS: One hundred twenty-three runners participated (83 males and 40 females, mean age 46.2 and 41.8 years, respectively). 44.5% of men and 62.5% of women had elevated risk for disordered eating. 37.5% of women reported a history of bone stress injury (BSI) and 16.7% had BMD Z scores <-1.0. 20.5% of men had a history of BSI and 30.1% had Z-scores <-1.0. Low body mass index (BMI) (<18.5 kg/m2) was seen in 15% of women and no men. The Triad Cumulative Risk Assessment classified 61.1% of women and 29.2% of men as moderate risk and 5.6% of both men and women as high risk.CONCLUSIONS: Our study is the first to measure BMD in both male and female ultramarathon runners. Our male population had a higher prevalence of low BMD than the general population; females were more likely to report history of BSI. Risk of disordered eating was elevated among our participants but was not associated with either low BMD or low BMI.
