The Relationship Between Iron Status and Adiposity in Women from Developing Countries: A Review

Abstract

Scientific reports have shown that iron deficiency is positively associated with adiposity. With the high prevalence of iron deficiency and obesity in developing countries and women being particularly affected, this review was carried out with the aim of elucidating the link between iron status and adiposity in women from developing countries and to examine factors influencing this relationship. An extensive literature search was conducted using several search engines. A systematic approach with prespecified inclusion criteria was used in selecting relevant literature. Eight studies that met the inclusion criteria were selected for review. The relationship between iron status indices and adiposity in women in developing countries varied widely. While some studies observed negative relationships, some reported positive relationships, and others no significant relationships. Furthermore, other factors such as infection, alcohol consumption, type of diet, and genes were shown to affect the relationship between iron status and adiposity in women in developing countries. In conclusion, the possibility of iron status playing a role in adiposity in women from developing countries is likely, and it may be influenced by several other factors as described in the results. Thus, it is recommended that a special research effort should be directed toward this area.
