Prenatal exposure to famine at the height of the famine (conception period) is associated with an increased risk of schizophrenia in the offspring.

This finding suggests that severe maternal malnutrition during the peri-conceptional period may disrupt early neurodevelopment, increasing the risk of schizophrenia. It underscores the importance of optimal nutrition before and during early pregnancy for long-term mental health.
