Tinea pedis in members of the Japanese Self-defence Forces: relationships of its prevalence and its severity with length of military service and width of interdigital spaces.
We examined the relationship between prevalence and severity of tinea pedis and the length of service and the width of the spaces between the toes in 74 members of the Japanese Self-Defence Forces (SDF) undergoing special training. The subjects were divided according to the width of these spaces into: group I, wide; group II, fairly wide; and group III, closed. The severity of tinea pedis was determined by its duration and the extent of the lesions in the 49 subjects who had tinea pedis. The combined prevalence of tinea pedis and tinea unguium was 66%. There was a tendency for the prevalence to be higher in subjects who had served for 10 years or more in the SDF than in those with fewer than 10 years of service. Classified by the disposition of their toes, 10 subjects fell into group I, 34 into group II, and 30 into group III. The prevalence of 90% (27/30) in group III was significantly higher than in the other groups. A significant positive correlation was seen between length of SDF service and severity. Subjects with both a long service record and closed interdigital spaces showed both a high prevalence and marked severity.
