Child Health Assessment and Monitoring Program (CHAMP)

Study Overview


The Child Health Assessment and Monitoring Program (CHAMP) is the first survey of its kind in North Carolina to measure the health characteristics of children, ages 0 through 17. By collecting data on children, CHAMP contributes to a seamless health data system for all North Carolina citizens from birth to old age. CHAMP was designed to meet the following goals: 1) Monitor the status of child health (ages 0–17) and identify child health problems in North Carolina; 2)Measure parents’ perspectives on child health issues. 3) Provide accurate and valid data to inform evidence-based decisions, strategies and policies to improve child health. 4) Assess relationships between parent health and child health, and inform family-centered approaches to improve child health. The CHAMP survey was first developed in the fall of 2004 and has been implemented annually since January 2005. Conducted in both English and Spanish, the CHAMP surveys are revised each year to meet the child health surveillance needs of North Carolina.

Sampling Procedures: 

The NC BRFSS and NC CHAMP surveys utilize disproportionate stratified random sampling (DSS). Telephone numbers are provided by the CDC/BSB and are generated from a computer in groups of 100 consecutive phone numbers that contain at least one published household telephone number. The telephone number groups are then assigned to two strata: (1) high-density or listed numbers, and (2) low-density or unlisted numbers. The listed numbers are sampled at a higher rate than unlisted numbers in an effort to achieve a higher hit rate (compared to simple random sampling) and still achieve a statistically representative sample. The ratio at which telephone numbers are sampled from each block is adjusted for through weighting when analyzing the data. Eligible children for the CHAMP survey are drawn each month from the North Carolina Behavioral Risk Factor Surveillance System (N.C. BRFSS) random telephone survey of adults, ages 18 and older. All adult respondents with children living in their households are invited to participate in the CHAMP 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.
