To identify whether calcium, vitamin D, and/or dairy intake are prospectively associated with stress fracture risk among female adolescents. Prospective cohort study. Adolescent girls living throughout the United States. A total of 6712 girls ages 9 to 15 years at baseline in the Growing Up Today Study, an ongoing prospective cohort study. Dairy, calcium, and vitamin D intake assessed by food frequency questionnaire every 12-24 months between 1996 and 2001. Incident stress fracture that occurred between 1997 and 2004, as reported by mother’s of the participants in 2004. Cox proportional hazards models were used to examine associations. During 7 years of follow-up, 3.9% of females developed a stress fracture. Dairy and calcium intake were unrelated to risk of developing a stress fracture. However, vitamin D intake was inversely related to stress fracture risk. The multivariable-adjusted hazard ratio (HR) of stress fracture for the highest versus the lowest quintile of vitamin D was 0.49 (95% CI=0.24-1.01; ptrend=0.07). We conducted a stratified analysis to estimate the association between vitamin D intake and stress fracture risk among girls participating in ≥1 hour/day of high-impact activity, among whom 90% of the stress fractures occurred, and found that higher vitamin D intake predicted significantly lower risk of stress fracture (ptrend=0.04) Vitamin D intake is associated with lower stress fracture risk among adolescent girls who engage in high levels of high-impact activity. Neither calcium nor dairy intake were prospectively associated with stress fracture risk.
