ABSTRACT
OBJECTIVES: Otitis media (OM) is a very common childhood disease and impacts child quality of life (QoL) to different extends. The aim of this study was to investigate the difference in quality of life between three groups of children; Children with symptoms of ear disease within the last 4 weeks, children without any ear disease and children scheduled for ventilating tube treatment. Furthermore, we investigated predictors for experiencing middle ear symptoms. Lastly, we assessed psychometric properties of OM-6 used to assess QoL. METHODS: Four hundred ninety-four children attending nursery day-care aged 6-36 months were enrolled in the study. Caregivers were asked to recall the child's history of symptoms related to middle ear infection. The Danish version of otitis media-6 questionnaire was used to measure the children's quality of life. Data from children treated with ventilating tubes were included from a previously published study. Logistic regression was applied for determining possible predictors for experiencing ear related symptoms. RESULTS: The study had an 87% response rate, with a total of 342 children included. At the inclusion 32 (9%) children were included in the 4-week group and, while 307 children were allocated to the non-4 week group. The children in the 4-week group were significantly younger and were more likely to have siblings with a history of middle ear infection than the non-4week group. Furthermore, QoL was significantly worse in the 4-week group compared to the non-4week group. Only subtle differences were found between children with acute symptoms compared to children scheduled for tube treatment. CONCLUSIONS: As expected, children with acute symptoms of OM experience lowered QoL compared to children with no symptoms and young age as well as having siblings with a history of middle ear problems were found to be possible predictors for experiencing middle ear symptoms. Children with acute symptoms differed from children scheduled for ventilating tubes on domains related to long-term problems from OM. OM-6 has shown to be a valid instrument for assessing disease specific QoL in children with OM, however a more large-scale instrument might be necessary for detecting subtle differences between subgroups of children with OM.
