A recent study published in the Journal of Children’s Orthopaedics suggests vitamin D deficiency may increase children’s risk of forearm fractures.
Researchers included a total of 30 children with a broken ulna and/or radius and 30 healthy controls. All children were between the ages of five and 10 years old. Medical history and anthropometric data were assessed. All participants received a serum blood draw measuring 25(OH)D, calcium, magnesium, phosphorus, alkaline phosphatase (ALP) and parathyroid hormone (PTH).
The Vitamin D levels were significantly lower in patients compared to controls (14.5 ng/ml vs 21.3 ng/ml, p = 0.002) Other blood measurements, such as calcium, magnesium, phosphorus, ALP and PTH did not demonstrate significant differences between broken arm patients and control patients.
The researchers administered 200 IU/kg body weight per day for 14 deficient patients in the broken arm group and three patients in control group. Suggestions for increased daily milk intake and sun exposure were advised to all of the injured children.
The researchers concluded:
“We have demonstrated with the present study the prevalence of vitamin D insufficiency or deficiency was higher in patients with forearm impaction type fracture than healthy controls and the baseline levels reported in the literature.”
“In addition, there were no significant differences in serum Ca, Mg, P, ALP and PTH levels between healthy controls and case patients. Further studies are needed in order to determine the relationship between vitamin D levels and bone turnover.”
