Low Parental Literacy Is Associated With Worse Asthma Care Measures in Children

ObjectiveTo determine whether parental literacy is related to emergency department visits, hospitalizations, and days of school missed for children with asthma.MethodsWe performed a retrospective cohort study at a university pediatric clinic. We enrolled children between 3 and 12 years old with a diagnosis of asthma and a regular source of care at the site of the study and their parent or guardian. Primary asthma care measures included self-reported rates of emergency department visits, hospitalizations, and days of school missed. Secondary asthma care measures included rescue and controller medication use, classification of asthma severity, and parental asthma-related knowledge.ResultsWe enrolled 150 children and their parents. Twenty-four percent of the parents had low literacy. Children of parents with low literacy had greater incidence of emergency department visits (adjusted incidence rate ratio [IRR] 1.4; 95% confidence interval 0.97, 2.0), hospitalizations (IRR 4.6; 1.8, 12), and days missed from school (IRR 2.8; 2.3, 3.4) even after adjusting for asthma-related knowledge, disease severity, medication use, and other sociodemographic factors. Parents with low literacy had less asthma-related knowledge, and their children were more likely to have moderate or severe persistent asthma and had greater use of rescue medications.ConclusionsLow parental literacy is associated with worse care measures for children with asthma.
