Physical activity, menstrual history, and bone microarchitecture in female athletes with multiple bone stress injuries Journal Article uri icon
Overview
abstract
  • PURPOSE: To determine differences in health and physical activity history, bone density, microarchitecture, and strength among female athletes with a history of multiple BSI, athletes with ≤ 1 BSI, and nonathletes. METHODS: We enrolled 101 women (age, 18-32 yr) for this cross-sectional study: nonathlete controls (n = 17) and athletes with a history of ≥ 3 BSIs (n = 21) or ≤ 1 BSI (n = 63). We collected subjects' health and training history and measured bone microarchitecture of the distal tibia via high-resolution peripheral quantitative computed tomography (HR-pQCT) and areal bone mineral density of the hip and spine by dual-energy X-ray absorptiometry. RESULTS: Groups did not differ according to age, body mass index, age at menarche, areal bone mineral density, or tibial bone microarchitecture. Women with multiple BSI had a higher prevalence of primary and secondary amenorrhea (P < 0.01) compared with other groups. Total hours of physical activity in middle school were similar across groups; however, women with multiple BSI performed more total hours of physical activity in high school (P = 0.05), more hours of uniaxial loading in both middle school and high school (P = 0.004, P = 0.02), and a smaller proportion of multiaxial loading activity compared with other groups. CONCLUSIONS: These observations suggest that participation in sports with multiaxial loading and maintaining normal menstrual status during adolescence and young adulthood may reduce the risk of multiple bone stress injuries.
