Características clínico-epidemiológicas de la alopecia androgenética en pacientes de un hospital de tercer nivel de Trujillo, Perú

Abstract

Objective

Androgenetic alopecia (AAG) is the progressive miniaturization of the hair follicle. This disease has an impact on the psychosocial aspect of the affected individuals. The aim of this article was to determine the clinical-epidemiological characteristics of AGA in adult patients in a tertiary hospital in Trujillo during 6 months.

Materials and methods

Prospective descriptive observational study. Data collection forms of patients older than 18 years with a diagnosis of AGA were used to obtain information.

Results

Of a total of 40 patients with AGA, 55% were male and 45% female, mainly aged 31–49 years and with a family history of AGA (72.5%). The typical grade IIIv pattern prevailed in males whose most frequent age range was 31–49 years. The diffuse grade I pattern (25%) predominated in females, who were < 70 years old. The most common disease time was 1–5 years, where the hair pull test was negative, predominantly in females (27.5%) and between 31 and 49 years of age (27.5%).

Conclusions

The majority of patients were 31–39 years old, male and with a family history of AGA; typical grade II and IIIv and diffuse grade I pattern predominated; disease time of 1–5 years and negative hair pull test.
