The Prenatal Nutrition and Psychosocial Health Outcomes (PreNAPS) study was a two year collaboration between Gulu, Makarere, Cornell, and Tufts Universities. The PreNAPs study's primary goals were: a) to determine the differential impacts of food insecurity on gestational weight gain and prenatal depression, and b) to elucidate the mechanisms underlying the relationship between food insecurity and weight gain and/depression among HIV infected and HIV uninfected pregnant women in Gulu, Northern Uganda.
