Linking nutrition and education: A cross-generation model

Abstract

Psychosocial influences, such as the family or the school, and biologic influences, such as nutrition or the presence of environmental toxins, can be viewed as elements of a child's overall environment. Family and school influences define dimensions of the child's psychosocial environment whereas nutrition and exposure to toxin define dimensions of the child's bioecologic environment. This paper presents a cross-generation model specifying both the nature and consequences of linkages between the psychosocial and bioecologic environments, with specific reference to schooling, nutrition, and development. Data from two studies done in Egypt and Peru are used to illustrate this model, showing how duration of breastfeeding and quality of the young child's diet are positively associated with higher levels of maternal education and intelligence. © 2005, The United Nations University.
