In nutritional research, investigators assessed the experiences of child food insecurity and seasonal instability within Mexican-origin mother-child dyads living in Mexico–U.S. border colonias. By focusing on food insecurity, which is known to cause health effects across a lifespan, investigators sought to understand the effects of school-based and summertime nutrition programs amongst women and their children, specifically within Texas-border colonias. An important attribute of this research was that the study depended on a multi-level analysis, which relied on repeated measurements. It also took into account the perceptions and experiences of children within the research.
