Vitamin D Deficiency
በዚህ ገጽ7 ክፍሎች
Overview
Vitamin D deficiency is extremely common in refugees, particularly those from tropical countries who have recently arrived in Canada, and those who wear covering clothing.
Screening
We do not routinely screen asymptomatic refugees for vitamin D deficiency. However, testing should be considered in:
- Patients with symptoms (bone pain, muscle weakness)
- Patients with risk factors for severe deficiency
- Pregnant and breastfeeding women
Risk Factors
- Dark skin pigmentation
- Covering clothing
- Limited sun exposure
- Northern latitude residence
- Obesity
Treatment
Deficiency (<30 nmol/L)
- Vitamin D3 2000-4000 IU daily, or
- 50,000 IU weekly for 8-12 weeks, then maintenance
Insufficiency (30-50 nmol/L)
- Vitamin D3 1000-2000 IU daily
Maintenance
Most refugees will benefit from ongoing supplementation of 1000-2000 IU daily, especially during winter months.
