Assessment of Vitamin A Supplementation Practices in Countries of the Eastern Mediterranean Region: Evidence to...

Vitamin A is an essential nutrient necessary for human growth and development, with critical roles in vision, immune function reproduction and maintenance of epithelial cellular integrity. Inadequate intake of vitamin A places populations at risk of developing diseases associated with vitamin A deficiency (VAD). VAD is highly prevalent across the Eastern Mediterranean Region (EMR) in children under 5 y and women of childbearing age. Therefore, infants and young children, pregnant women and postpartum women are commonly targeted by supplementation programs. Although, vitamin A supplementation has been shown to decrease preventable childhood diseases and deaths related to VAD, supplementation of vitamin A has been greatly misused in several countries within the EMR raising concern around the process of supplementing the target population. Countries across the EMR have reported different supplementation practices depending on the income level of the country, the availability of vitamin A and the prevalence rates of VAD. Although some countries had higher supplementation rates than others, the concern lies in the middle-income countries and their supplementation practices. Some of the countries across the region do not follow the World Health Organization's (WHO) guidelines for vitamin A supplementation for the recommended age groups. The objective of this study is to assess the vitamin A supplementation practices across the countries in the EMR, determine the gaps in the supplementation practices and the issue with supplementing to healthy populations where VAD is not a public health concern, and provide recommendations for proper vitamin A supplementation within the region.
