足白癬・爪白癬の疫学調査が世界的な規模で行われ,その罹患率は足白癬・爪白癬がそれぞれ約20%に認められ,ともに男性に多く,加齢とともにその罹患率が上昇することが明らかにされた.罹患のリスク因子として,スポーツ,平均気温,家族歴あり,罹患と関係する疾患としては,高コレステロール血症,心・血管疾患,糖尿病,骨・関節の病気などとの関係が深いことが指摘された.われわれは,医療機関を受診しない潜在的な足白癬・爪白癬患者の実態調査を試みた.その結果,潜在的足白癬・爪白癬の特徴は,男性に多く,症状スコアは低く,重症度は高い傾向がみられた,その患者背景をみるとKOH検査結果との間で罹患歴,年齢,足の形,合併症,常用している靴の種類などの間で相関関係が認められた.足白癬・爪白癬は,局所的および全身的要因が,年齢とともに互いに作用し,白癬菌の好環境を作ることにより,罹患率が上昇すると推察した.今後さらに潜在的足白癬・爪白癬の実態を明らかにすることが,両疾患の予防,診断,治療成績などの向上に役立つと考えた.

Epidemiological studies on tinea pedis and onychomycosis have been performed across Europe and East Asia. The prevalence of these conditions was 20%, respectively, and it increased with advancing age, more men than women had fungal infection of the feet. The prevalent predisposing factors were sports participation, average temperature, and family history of tinea pedis. The predisposing diseases were hypercholesterolemia, cardiovascular disease, diabetes mellitus, and osteoarticular disease. We conducted an epidemiological investigation to determine the prevalence and circumstances of untreated and unsuspected tinea pedis and onychomycosis. The results showed that the prevalence of occult athlete's foot was 25%, and that 59% of those cases were complicated by tinea unguium. The characteristics of patients with occult athlete's foot included a higher proportion of men and a tendency toward a low clinical score together with a high severity score. In the patient background, a strong correlation was observed between a positive KOH test result and characteristics such as past history of tinea pedis and/or onychomycosis, age, disposition of toes, and predisposing disease, as well as the type of shoes worn daily. We suspected that a patient's local and systemic conditions affected each other, creating good conditions for tinea pedis and onychomycosis so that the prevalence has increased. More understanding of occult athlete's foot will lead to prevention and improvement in treatment and diagnosis.
