2005 California Health Interview Survey

Calls are going out throughout California to gather valuable information from residents on a variety of health topics, such as access to medical care, health insurance, chronic illnesses, children's health and health-related behaviors. Conducted every two years by the UCLA Center for Health Policy Research, the California Health Interview Survey (CHIS) provides the most comprehensive overview of this state's diverse population on health issues. The 2005 telephone survey began on July 11, and by the time it is completed in December, tens of thousands of California residents will have participated.

A collaborative project of the UCLA Center for Health Policy Research, the California Department of Health Services, and the Public Health Institute, CHIS is a vital resource for policymakers, health planners, community groups, health advocates and others working to improve the health of all Californians. For example, data from earlier rounds of the survey conducted in 2001 and 2003 have been used to expand health insurance access for children and develop policies to address obesity, asthma and other conditions.

You can help make the 2005 survey a success by encouraging the public to participate if they are called. If more people "Take the Call," then those using CHIS data to make important decisions on health policy will be better equipped to do their jobs. "Take the Call" flyers are available in five languages (English, Spanish, Chinese, Korean and Vietnamese) and can be posted or handed out to individual members of the public.

In addition, the health departments in San Diego, Marin and Solano Counties have commissioned locally funded oversamples of their counties.
