What is an 'otitis-prone' child?
Insights
Identifying children prone to acute otitis media (AOM) is crucial. A new criterion identified 10.8% of children as otitis-prone, but early AOM onset was a weak predictor of susceptibility.
Area of Science:
- Pediatrics
- Otolaryngology
- Epidemiology
Background:
- Acute otitis media (AOM) is a common childhood illness.
- Previous definitions of 'otitis-prone' populations vary widely.
- Accurate identification of susceptible children is clinically important.
Purpose of the Study:
- To evaluate a new criterion for identifying children at high risk for recurrent acute otitis media.
- To assess the predictive value of early-onset AOM for later susceptibility.
Main Methods:
- A cohort of 2512 children was monitored for AOM up to age two.
- A criterion of at least 4 AOM episodes in 9 months, with a 30-day separation, was applied.
- Sensitivity and predictive values of early AOM onset were analyzed.
Main Results:
- A new criterion identified 273 children (10.8%) as otitis-prone at a mean age of 15 months.
- This definition provided an acceptable mean age for identification.
- Early onset of AOM demonstrated low sensitivity and predictive values, indicating weak predictive power.
Conclusions:
- The proposed criterion effectively identifies a subset of children with recurrent AOM.
- Early AOM onset is not a reliable predictor for identifying susceptible children.
- Further research is needed to refine predictive models for otitis-prone individuals.
Abstract:
The present report concerns a random sample of 2512 children monitored for acute otitis media up to the age of two years. The criteria given by previous surveys classified from 1.8 to 41.2% of the population as 'otitis-prone', at a mean age varying between 13.4 and 18.8 months. A criterion of at least 4 episodes of acute otitis media during the next 9 months with a 30-day borderline between two distinct episodes yielded 273 children (10.8% of the population) with an acceptable mean age of 15 months. Early onset of acute otitis media was only a weak predictor of susceptibility in either the individual child or the whole population, the sensitivity levels and predictive values being too low for accurate prediction.
