Research is needed to examine what factors determine the health care utilization patterns of Hispanic children with asthma. The purpose of this study was to profile California's Hispanic children with asthma, from 1 to 5 years of age, including their demographics, their health care access, their asthma severity, their disability due to asthma, and their health care utilization patterns. An overall sample of 149 children (N = 149) was used, whose parents reported that they were Hispanic and had a current MD diagnosis of asthma.
