This article measures rates of hunger and food insecurity among young US-born Latino children with Mexican immigrant parents compared with a non-immigrant, non-Latino population.  A sample of 1,310 households with one parent born in Mexico was compared to a reference group of 1,805 non-Latino US-born participants.  Young Latino children had much higher rates of child hunger and household hunger than non-Latino children. Public health officials and policy makers should be attentive to the issues of hunger and food insecurity and its effects on child health in this growing high-risk population.
