Do children whose parents use physical punishment as a disciplinary method have lower anthropometric measures? Using data for Peruvian children aged 0–5 years, we employ instrumental variables for physical punishment to overcome endogeneity problems common to the household violence literature. Across varying levels of controls, children exposed to physical punishment have significantly poorer short-term nutritional outcomes; although there is no effect on long-term nutrition. We explore heterogeneous effects and potential mechanisms. Children exposed to physical maltreatment fall ill more frequently and are less likely to access preventive and curative healthcare.
