How CHIS was administered in the BHC Sites?
The California Health Interview Survey (CHIS) is an ongoing comprehensive public health survey that provides health data for the state and counties in California. To gather meaningful health data for "Building Health Communities" (BHC), The California Endowment supported a CHIS 2009 oversample in 14 BHC sites.
 
Households in each BHC site were randomly selected to participate through random digit dial (RDD) telephone sampling. Given the focus of BHC efforts on children and families, adult eligibility included being a parent of a child under age 18 or an adult age 18 to 40. Children age 0 to 11 and teens age 12 to 17 were also eligible. For children, interviews were administered with the adult most knowledgeable about that child; for teens, interviews were administered with the teen after obtaining parent's permission. County and state estimates come from CHIS 2009 and maintain the same eligibility criteria as the BHC site. Over 500 interviews were completed in each of the 14 BHC sites between April and September 2010.
 
Results provided in this health profile represent estimated values for the eligible population of the designated BHC site, its respective county and California. Estimates are based on the selected sample of the overall eligible population and thus have a degree of uncertainty. The data provided display 95% confidence intervals (CIs) indicating that we are 95% confident that the actual value of the health outcome lies between the lower and upper CI range. Estimates with wide CIs should be interpreted with caution.
