Insights
Hospitalization for otitis media (OM) in early childhood was linked to slightly lower cognitive function in adulthood. However, OM hospitalizations did not significantly affect General Certificate of Secondary Education (GCSE) achievement.
Area of Science:
- Pediatrics
- Neuroscience
- Public Health
Background:
- Otitis media (OM) is a prevalent childhood illness impacting critical developmental periods.
- Early childhood OM may affect cognitive and educational trajectories into adulthood.
Purpose of the Study:
- To investigate the association between early childhood hospitalisation for OM and cognitive function in early adulthood.
- To examine the relationship between early OM hospitalisation and educational attainment (GCSE).
Main Methods:
- Population-based cohort study using Danish healthcare and conscription records (1977-1983).
- Identified OM hospitalisations before age 8.
- Assessed cognitive function using the Boerge Prien intelligence test (BPP) and educational level (GCSE).
- Adjusted for confounders and stratified by hearing impairment.
Main Results:
- Hospitalisation with OM before age 8 was associated with a higher prevalence of lower cognitive function (BPP bottom quartile: PR 1.20).
- No significant difference in GCSE prevalence was observed based on early OM hospitalisation.
- The association between OM and cognitive function persisted across different BPP score levels and hearing impairment statuses.
Conclusions:
- Early childhood hospitalisation for otitis media is associated with a modest decrease in cognitive function in early adulthood.
- Hospitalisation for OM does not appear to significantly impact the likelihood of achieving a GCSE, even when cognitive function is considered.
Background:
Otitis media (OM) is a very common condition in children and occurs during years that are critical to the development of learning, literacy, and math skills. Therefore, among a large cohort of Danish conscripts, we aimed to examine the association between hospitalisation with OM in early childhood and cognitive function and educational level in early adulthood.
Methods:
We conducted a population-based prevalence study using linked data from healthcare databases and conscription records of Danish men born between 1977 and 1983. We identified all hospitalisations with OM before 8 years of age. Cognitive function was measured by the Boerge Prien validated group intelligence test (Danish Børge Prien Prøve, BPP). We adjusted for potential confounders with and without stratification by hearing impairment. Furthermore, we examined the association between hospitalisation with OM and the prevalence of having achieved a General Certificate of Secondary Education (GCSE), stratified by quartiles of BPP scores.
Results:
Of the 18 412 eligible conscripts aged 18-25 years, 1000 (5.5%) had been hospitalised with OM before age 8. Compared with conscripts without such a record, the adjusted prevalence ratio (PR) for a BPP score in the bottom quartile was 1.20 (95% confidence interval [CI]: 1.09-1.33). There was no major difference in the proportion of men with a GCSE and those without among those hospitalised with OM in early childhood. For men in the bottom and upper quartiles of BPP scores, the PRs for early childhood hospitalisation with OM were 0.89 (95% CI: 0.59-1.33) and 0.96 (95% CI, 0.88-1.05), respectively. Among men with severe hearing impairment, the proportion with a BPP score in the bottom quartile did not differ between those with and without an OM hospitalisation [PR = 1.01 (95% CI: 0.78-1.34)].
Conclusions:
Overall, we found that hospitalisation with OM in early childhood was associated with a slightly lower cognitive function in early adulthood. Hospitalisation for OM did not seem to influence the prevalence of GSCE when level of BPP was taken into account.
