California's Maternal and Infant Health Assessment
California's Maternal and Infant Health Assessment (MIHA) is an annual survey of California women who recently gave birth to a live infant. It collects population-based data on maternal attitudes and experiences before, during, and shortly after pregnancy. The survey is based on the national Pregnancy Risk Assessment Monitoring System (PRAMS), operated by the CDC. The goal of MIHA is to improve the health of mothers and infants by reducing adverse outcomes such as low birth weight, infant mortality and morbidity, and maternal morbidity. MIHA combines data from birth certificates with survey data obtained from a sample of women who have had a recent birth.
