This report provides a summary of the statewide findings from the 2005 California Health Interview Survey (CHIS), with highlights of changes from 2003 to 2005. In dozens of easy-to-read tables and graphs, the report features more than 80 health indicators on topics that include asthma, obesity, health insurance and health care access. It shows findings by age, gender, race and ethnicity, income level and health insurance status. The information was collected over two survey periods, allowing the report's authors to note significant changes between 2003 and 2005 in the health of Californians. Conducted every two years, CHIS is the nation's largest state health survey and CHIS data represents the most up-to-date and comprehensive information on the health of Californians. CHIS is conducted by the UCLA Center for Health Policy Research in collaboration with the California Department of Public Health, the Department of Health Care Services and the Public Health Institute.
