Background:
In recent years we have seen an increasing number of children in Israel with tinea pedis.
Objective:
To determine the prevalence of tinea pedis in 5- to 14-year-old schoolchildren in a comprehensive epidemiologic population-based study.
Methods:
A total of 1148 children, ages 5 to 14 years, from 7 schools with different socioeconomic backgrounds from the Jerusalem area were examined for the presence of tinea pedis. Scrapings from suspected lesions of fungal infection were sent to a mycologic laboratory for KOH microscopy and fungal identification. Information on the children's background and predisposing factors (regarding living conditions, hygiene, etc.) were provided by means of questionnaires filled out by each child.
Results:
Of the 1148 children examined, 29.6% exhibited erythema and scaling, but only 6.9% of these were mycologically positive for tinea pedis. was the main causative agent (68%) of tinea pedis. The prevalence of tinea pedis increased with age, hyperhidrosis and particularly repeated foot washing (a 3.2 higher rate in children who washed their feet twice a day those who did not wash daily).
Conclusion:
The prevalence of tinea pedis in children has increased in recent decades in Israel and should be considered in the differential diagnosis of dermatologic diseases affecting the feet. Washing habits have a significant effect on tinea pedis in children.
