Abstract
Iron deficiency (ID) is a common problem among US children but diagnosis requires four tests. An equation using only the logarithmic ratio of circulating transferrin receptor to ferritin has been proposed to quantify body iron in adults, however, its application in children is limited. Our objective was to determine the body iron of middle-class US toddlers using this equation and to compare calculated body iron to dietary and anthropometric covariates previously associated with ID. Eighty-six healthy, 18-to 36-month-old toddlers were recruited. Anthropometric, dietary, and hematological data were collected. Multiple regression analyses revealed dietary calcium intake and body mass index negatively influenced body iron, and birth weight, dietary iron intake, and energy intake positively influenced body iron. These predictive variables are similar to previously reported iron status risk factors. Our findings support the use of the body iron equation as a simple measure of iron status in healthy young children.
