Does otitis media in early childhood affect later behavioural development? Results from the Western Australian Pregnancy Cohort (Raine) Study. (2nd April 2018) - Da Costa, C.
Abstract : Objectives: To examine the relationship between early life episodes of otitis media and later behavioural development with adjustment for confounders. Design: Longitudinal cohort study. Setting: The Western Australian Pregnancy Cohort (Raine) Study recruited 2900 pregnant women from King Edward Memorial Hospital (KEMH) in Perth, Western Australia, between 1989 and 1991. Participants: Data from the children born were collected at both the Year 3 and Year 5 follow‐up. At Year 3, n = 611 were diagnosed with recurrent otitis media through parent‐report and clinical examination. At Year 5, n = 299 were considered exposed to otitis media based upon tympanometry results. Main outcome measures: Performance in the Child Behaviour Checklist (CBCL), a questionnaire completed by the primary caregiver at Year 10. Results: Significant associations were found between recurrent otitis media at Year 3 and internalising behaviours ( P = .011), and the somatic ( P = .011), withdrawn ( P = .014), attention ( P = .003) and thought problems domains ( P = .021), and the total CBCL score ( P = .010). A significant association was also found between exposure to otitis media at Year 5 and externalising behaviours ( P = .026). Conclusions: A modest association was seen between recurrent otitis media at Year 3 and exposure to otitis media at Year 5 and a number of behaviour domains at Year 10.
