External otitis among swimmers and nonswimmers

A W Hoadley, D E Knight

    Archives of Environmental Health

    Summary
    This summary is machine-generated.

    Swimming significantly increases the risk of developing external otitis (swimmer's ear), with infections being more frequent and severe in swimmers. Pseudomonas aeruginosa is more commonly found in swimmer's ear infections.

    Area of Science:

    • Otolaryngology
    • Infectious Diseases
    • Public Health

    Background:

    • External otitis, commonly known as swimmer's ear, is an infection of the outer ear canal.
    • Swimming is frequently implicated as a contributing factor to the development of external otitis.

    Purpose of the Study:

    • To investigate the relationship between swimming and the incidence of external otitis.
    • To determine the effect of swimming on the isolation of Pseudomonas aeruginosa in outer ear infections.

    Main Methods:

    • A telephone survey was conducted in 1971 to assess earache frequency in swimmers versus nonswimmers.
    • Physician reports of outer ear infections were collected between 1970 and 1974 to determine infection risk.
    • The prevalence of Pseudomonas aeruginosa in infected ears was analyzed.

    Main Results:

    • Swimmers reported earaches 2.4 times more frequently than nonswimmers.
    • The risk of acquiring external otitis was approximately five times higher for swimmers compared to nonswimmers.
    • Swimming increased the risk of Pseudomonas aeruginosa involvement and led to more severe infections.

    Conclusions:

    • Swimming is a significant risk factor for developing external otitis.
    • Swimmer's ear infections are associated with a higher incidence of Pseudomonas aeruginosa and increased severity.
