thus reducing the ability to detect associations between food insecurity and health outcomes given the low incidence of food insecurity among populations at higher income levels. In addition, most of these samples were not diverse enough to examine these associations within the racial/ethnic groups that experience food insecurity most acutely and chronically. The important point that I would like to make is that until we conduct well-designed studies (i.e., longitudinal studies with large samples of low-income children), we cannot derive any conclusions about the association between food insecurity and obesity in children. We need better-designed studies that examine longitudinally how food security status and changes affect birth outcome and early growth as well as the later risk of obesity; currently there is a paucity of such studies.
