Objectives: To examine any racial and ethnic differences in health care utilization among children with asthma by application of the Aday and Anderson’s behavioral model of health care utilization.
Methods: The California Health Interview Survey (CHIS) is a noninstitutionalized household survey of California residents conducted biannually since 2001. Cross-sectional survey data were analyzed to identify differences by race and ethnicity among children with asthma. After adjusting for sample weights and design effects, children with asthma comprised a sample size of 400,000 in the 2007 CHIS database. Disparities in health care utilization across all racial and ethnic categories were analyzed using multivariate logistic regression analysis.
Results: Latino children with asthma were 49% more likely to have visited an emergency department in the previous year (P < 0.05) and 57% less likely to have visited a doctor (P < 0.05) compared with non-Latino children with asthma, after controlling for confounding variables. Furthermore, Puerto Rican children were 72% more likely to have visited an emergency department (P < 0.05) in the previous year and 38% less likely to have visited a doctor (P < 0.07) compared with non-Puerto Rican children.
Conclusion: This study provides evidence of disparities in health care utilization among Latino children overall as well as in Latino children belonging to different subgroups suffering from asthma. Examining factors leading to differences within the Latino subgroups could help to guide the tailoring of interventions and health care programs for children with asthma, thereby improving access to health care services for this underrepresented minority.
