Maternal and Infant Health Assessment (MIHA)
The Maternal and Infant Health Assessment (MIHA) is an annual, statewide-representative survey of California residents with a recent live birth.
MIHA collects self-reported information about maternal and infant experiences and about maternal attitudes and behaviors before, during and shortly after pregnancy. To read more about how MIHA data are used to guide public health programs and services to improve the health of mothers and infants in California go to our Successes page.
MIHA is a collaborative effort of the Maternal, Child and Adolescent Health (MCAH) and the Women, Infant & Children (WIC) Division of the California Department of Public Health and the Center for Health Equity at the University of California, San Francisco . The MIHA project is supported by the California Department of Public Health using federal funds from the Title V Maternal and Child Health Block Grant and the Special Supplemental Nutrition Program for Women, Infants and Children.
