California's Maternal and Infant Health Assessment (MIHA) is a statewide representative annual survey of California women who recently gave birth to a live infant, sampled from birth certificates. It collects population-based data on maternal attitudes and experiences before, during, and shortly after pregnancy. The survey is analogous to the Pregnancy Risk Assessment Monitoring System (PRAMS), operated by the Centers for Disease Control and Prevention (CDC). The goal of MIHA is to improve the health of mothers and infants by providing data to inform programs and policies aimed at reducing adverse outcomes such as low birth weight, infant mortality and morbidity, and maternal morbidity. MIHA survey responses are linked to birth certificate data and weighted to represent all women in California with a live birth each survey year.
