To examine the prevalence of two ISAAC (International Study of Asthma and Allergies in Childhood) asthma indicators in 7 European countries and their relationship with mental health disorders in children 6–12 years.
MethodsA cross-sectional survey of 5712 school children aged 6–12 years using a video Self-administered instrument: Dominic Interactive and the Strengths and Difficulties Questionnaire (SDQ) for parents and teachers. Asthma indicators were 12 month “Wheezing or whistling in the chest” (WWC) and “Severe Asthma” (SA) based on number of attacks of wheezing, sleep disturbance due to wheezing, and limits to speech.
ResultsOn average 7.31% of the children had WWC, from 15.09% in Turkey to 1.32% in Italy; SA 2.22% on average ranged from 4.78% in Turkey to 0% in Italy. Generalized Anxiety Disorder (GAD) from child self-reports was significantly associated with WWC and SA even after adjustment for covariates. Based on parent and teacher combined reports, emotional problems were found to have significant associations with 12-month WWC after adjustment, as well as “any problems” which summarized externalizing and internalizing disorders Emotional, hyperactivity, conduct disorders were not associated with SA.
ConclusionAsthma indicators very much differ across countries. Asthma indicators are associated with childhood GAD. Childhood self-reported mental health seems more related to Asthma indicators than parents/teachers combined reports.
