PURPOSE: Asthma prevalence is increasing but it is difficult to identify children at risk for asthma, thus many at-risk children remain undiagnosed. We hypothesized that a history of asthma-like symptoms within the previous year would be a useful tool to identify children at risk for asthma, and for referral to a physician.
METHODS: After local IRB approval, we recruited 103 children and families from a church and a school in a largely African American community. Parents responded to a validated questionnaire about whether or not their children experienced four asthma-like symptoms in the past year (wheezing, night time cough, exercise limitation, or prolonged colds lasting for ≥10 days). Twenty of the children were already diagnosed with asthma by their primary care physician. We compared their asthma-like symptoms with 83 children who had not been diagnosed with asthma.
RESULTS: The prevalence, or pre-test probability that a child in this community may have asthma was 19.4%. Two or more symptoms were reported by 95% (n=19) of children with asthma and 43.4% (n=36) of children without a diagnosis of asthma. Based on a likelihood ratio of 2.2, the post-test probability that a child in the community may have asthma increased to 35% when children had two or more symptoms. The odds that a child with ≥2 symptoms had asthma were 24.8 times greater than children who had 0 or 1 symptom.
CONCLUSIONS: This brief screening tool can be useful to identify children with potentially undiagnosed asthma.
CLINICAL IMPLICATIONS: With better diagnosis of asthma, at risk children can identified early and can be referred to a physician for close follow-up.
