This study aimed to investigate associations between menstrual function, eating disorders, and risk of low energy availability with musculoskeletal injuries in British servicewomen.
All women younger than 45 yr in the UK Armed Forces were invited to complete a survey about menstrual function, eating behaviors, exercise behaviors, and injury history.
A total of 3022 women participated; 2% had a bone stress injury in the last 12 months, 20% had ever had a bone stress injury, 40% had a time-loss musculoskeletal injury in the last 12 months, and 11% were medically downgraded for a musculoskeletal injury. Menstrual disturbances (oligomenorrhea/amenorrhea, history of amenorrhea, and delayed menarche) were not associated with injury. Women at high risk of disordered eating (Female Athlete Screening Tool score >94) were at higher risk of history of a bone stress injury (odds ratio (OR; 95% confidence interval (CI)), 2.29 (1.67-3.14); P < 0.001) and time-loss injury in the last 12 months (OR (95% CI), 1.56 (1.21-2.03); P < 0.001) than women at low risk of disordered eating. Women at high risk of low energy availability (Low Energy Availability in Females Questionnaire score ≥8) were at higher risk of bone stress injury in the last 12 months (OR (95% CI), 3.62 (2.07-6.49); P < 0.001), history of a bone stress injury (OR (95% CI), 2.08 (1.66-2.59); P < 0.001), a time-loss injury in the last 12 months (OR (95% CI), 9.69 (7.90-11.9); P < 0.001), and being medically downgraded with an injury (OR (95% CI), 3.78 (2.84-5.04); P < 0.001) than women at low risk of low energy availability.
Eating disorders and risk of low energy availability provide targets for protecting against musculoskeletal injuries in servicewomen.
本研究旨在调查英国女兵的月经功能、饮食障碍和低能量状态与肌肉骨骼损伤之间的关系。
所有年龄在 45 岁以下的英国武装部队女性均被邀请参与一项关于月经功能、饮食行为、运动行为和受伤史的调查。
共有 3022 名女性参与了研究；2%的人在过去 12 个月内发生过骨应激损伤，20%的人曾发生过骨应激损伤，40%的人在过去 12 个月内发生过因伤缺勤的肌肉骨骼损伤，11%的人因肌肉骨骼损伤而被降级。月经紊乱（少经/闭经、闭经史和初潮延迟）与损伤无关。处于饮食障碍高风险（女性运动员筛查工具评分＞94）的女性发生骨应激损伤史（比值比（OR）；95%置信区间（CI））、过去 12 个月因伤缺勤（OR（95%CI））的风险更高，为 2.29（1.67-3.14）；P＜0.001）和 1.56（1.21-2.03）；P＜0.001）。低能量状态高风险（女性低能量状态问卷评分≥8）的女性发生过去 12 个月骨应激损伤的风险更高（OR（95%CI），3.62（2.07-6.49）；P＜0.001）、骨应激损伤史（OR（95%CI），2.08（1.66-2.59）；P＜0.001）、过去 12 个月因伤缺勤（OR（95%CI），9.69（7.90-11.9）；P＜0.001）和因伤被降级（OR（95%CI），3.78（2.84-5.04）；P＜0.001）的风险高于低能量状态低风险的女性。
饮食障碍和低能量状态的风险为保护女兵免受肌肉骨骼损伤提供了目标。
