Vitamin D May Reduces Stress Fractures in Adolescent Girls

For girls who engage in high-impact activity, high vitamin D levels significantly lower fracture risk

TUESDAY, March 6 (HealthDay News) -- High intake of vitamin D is associated with a reduced risk of stress fractures in adolescent girls, particularly for those who engage in high-impact activity, according to a study published online March 5 in the Archives of Pediatrics & Adolescent Medicine.

To investigate the association between calcium, vitamin D, and/or dairy intake and stress fractures, Kendrin R. Sonneville, Sc.D., R.D., of the Children's Hospital Boston, and associates conducted a prospective study of 6,712 adolescent girls aged 9 to 15 who completed a food frequency questionnaire every 12 to 24 months between 1996 and 2001.

During seven years of follow-up, the researchers found that 3.9 percent of participants developed a stress fracture, predominantly from high-impact sports. Intake of dairy and calcium was not associated with stress fracture risk, while there was an inverse correlation between vitamin D intake and stress fracture risk. For the highest versus the lowest quintile of vitamin D intake, the multivariable hazard ratio of stress fracture was 0.49 (Ptrend = 0.07). For girls participating in at least one hour per day of high-impact activity, higher vitamin D intake was associated with a significantly reduced 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," the authors write. "Neither calcium intake nor dairy intake was prospectively associated with stress fracture risk."
