A Clinical Study of Childhood Alopecia Areata in Chandigarh, India

Abstract

All new cases of alopecia areata (AA) were studied during the years 1983–1993. Eight hundred forty-one cases were recorded, including 201 (23.9%) children less than 16 years of age. The female:male ratio was 1.4:1 (117 girls, 84 boys) for childhood AA. Alopecia was severe, (hat is, total, universal, or extensive, in 34(16.9%) children. Onset occurred in 77 (38.3%) children between ages 6 and 10 years, In 67 (33.3%) before 5 years of age, and in 57 (28.4%) between 11 and 16 years. Onset before 5 years of age was more often associated with severe alopecia than onset at ages 11 to 16 years (p < 0.01). Onset before 2 years of age was commonly associated with severe alopecia, seen in 6 (55.5%) of 11 children. Twenty-five (12.4%) children had one or more family members with AA. Definite evidence of atopy was obtained In 35 (17.5%) children. Association of atopy with severe alopecia was not statistically significant at Initial presentation (16% vs 23.5% for circumscribed and severe alopecia, respectively; p > 0.05). Nail changes were found In 60 (30%) children and were more frequent in severe alopecia (53%) than in circumscribed alopecia (25.2%, p < 0.001). Associated vittllgo was found in seven (3.5%) children, and one child was hypothyroid. Childhood AA in Chandigarh, India, is remarkably similar to that seen in Western countries, except that an association of atopy with younger age at onset and severe alopecia was not confirmed.
