Children's Health Assessment Survey (CHAS) Overview

Chas Logo Overview

The Children's Health Assessment Survey (CHAS) is the first survey of its kind in South Carolina to measure the health characteristics of children, ages 0 through 17. By collecting data on children, CHAS contributes to a seamless health data system for all South Carolina citizens from birth to old age. The CHAS survey was first developed in the fall of 2011 and has been implemented annually since January 2012. Conducted in both English and Spanish, the CHAS surveys are revised each year to meet the child health surveillance needs of South Carolina.

Eligible children for the CHAS survey are drawn each month from the South Carolina Behavioral Risk Factor Surveillance System (SC BRFSS) telephone survey of adults, ages 18 and older. All adult respondents with children living in their households are invited to participate in the CHAS survey. One child is randomly selected from the household, and the adult most knowledgeable about the health of the selected child is interviewed in a follow up survey.

Questions on the CHAS survey pertain to a wide variety of health-related topics, including breast feeding, early childhood development, access to health care, oral health, mental health, physical health, nutrition, physical activity, family involvement and parent opinion on topics such as tobacco and childhood obesity. This annual survey provides valid and reliable data on health issues of South Carolina children that can be used to monitor child health status and identify priority areas at the state level; help track progress of health programs over time and assist in altering programs to best meet the needs of South Carolinians; assist health professionals in making evidence-based decisions, policies and program strategies and monitor progress towards selected health targets, such as Healthy Carolinians 2010 and 2020.
