Identifying nutrition problems after the emergency phase of a disaster has passed is a critical priority in humanitarian response. Population displacements following hurricane flooding can promote household food shortages that persist after direct effects of the natural hazard have waned. This article examines preexisting social vulnerability and reconstruction effects as critical factors for under-five child nutritional status, alongside proximal household and child predictors. The study focuses on post-hurricane reconstruction almost two years after Hurricane Mitch in Honduras, and compares shelters in the capital with the settlement of Ciudad Nueva, Choluteca. Results have implications for humanitarian assistance practices and policy.
