Does Your Child Have Asthma? Filled Prescriptions and Household Report of Child Asthma

IntroductionSurveys are central for information on asthma prevalence. Recently, the validity of parental reports of pediatric asthma has been questioned. Confidence is examined in the report of asthma for children, obtained in a survey from the adult household member most knowledgeable about household health care (MKA).MethodMKA reports of asthma are compared with pharmacy records of prescriptions beneficial in asthma treatment (“asthma medications”) for children 0 to 17 years old in the 1996 Medical Expenditure Panel Survey.Results“Asthma medications” were filled for 6.5% of children, yet the MKA did not report asthma for 47.3% of them. However, for 61.2% of these children, the MKA reported plausible alternative medical conditions. For 9.0%, diagnosis information was missing. Among children with an “asthma medication,” the MKA was less likely to report either asthma or a plausible alternative diagnosis for girls and for children 0 to 5 years of age. Reporting was not statistically different by child race/ethnicity, household income, education level, and MKA English language proficiency.DiscussionSurveys do not overlook as many children with asthma as previously reported. Among children with “asthma medications,” only sex and age appear to be different for children whose MKA reported either asthma or a plausible alternative diagnosis versus those whose MKA did not report either.
