ABSTRACT
Vitamin D deficiency is common in Arab women, In a pilot study we investigated the effect of sun exposure at recommended levels on the vitamin D status of Arab women. Eight healthy Arab women of child-bearing age consented to expose their face, arms and hands for 15 minutes per day twice a week for 4 weeks within the privacy of their courtyard and to avoid changes in dietary vitamin D intake. Serum 25-hydroxyvitamin D [25[OH]] levels were measured pre- and post-intervention. Although vitamin D levels remained sub-optimal, median serum 25[OH]D levels were significantly higher post-intervention [23.0 nmol/L] than pre-intervention [17.6 nmol/L]. Extending sun exposure for more than 4 weeks should be investigated as part of strategies to improve vitamin D status in high-risk Arab women who lack outdoor sun exposure to the skin
