This leads to a wide misconception that vitamin D deficiency is rare in Africa. In fact, this study finds that vitamin D deficiency is similar to that in Europe and is likely to increase further with urbanisation.

CITATION: Prevalence of vitamin D deficiency in Africa: a systematic review and meta-analysis

‘We did a systematic review and meta-analysis of the prevalence of vitamin D deficiency in populations living in Africa to guide prevention, detection, and control strategies… In conclusion, we found that vitamin D deficiency, as defined by three different thresholds, is prevalent in Africa, particularly in newborn babies, women, urban populations, and populations living in northern African countries and South Africa. Strategies to prevent, detect, and treat vitamin D deficiency need to be incorporated into public health and primary care in Africa. Therefore, we recommend the development of governmental policies and nutritional guidelines to improve vitamin D status, and dietary calcium intakes when appropriate, of African populations as has been done in other continents and countries.’
