Abstract
in English, Portuguese

Brittle Nails Syndrome is characterized by fragility of the nail plate, affecting 27% of women. We evaluated dermatology patients in a cross-sectional study about perception of nail fragility. One hundred and thirty eight women were included, with median age of 36.5 years. Nail examination showed changes in 57% and 49% reported nail fragility. The first three fingernails were the most affected. Onychoschizia was related to onychophagia (OR = 3.29), housework (OR = 2.95) and water contact (OR = 2.44). Onychorrhexis had the strongest association with nail fragility perception (OR = 17.89). The fragility was more perceived by those who were black, of mixed race and atopic, and was associated with depressed mood.

A síndrome das unhas frágeis caracteriza-se por fragilidade da lâmina ungueal, acometendo 27% das mulheres. Realizamos estudo transversal com pacientes dermatológicas sobre a percepção de fragilidade ungueal. Avaliamos 138 pacientes com idade mediana de 36,5 anos. Ao exame, 57% apresentavam alterações e 49% relatavam fragilidade ungueal. Os três primeiros dedos das mãos foram os mais acometidos. A onicosquizia associou-se com onicofagia (OR = 3,29), trabalhos domésticos (OR = 2,95) e contato com água (OR = 2,44). A onicorrexe teve a mais forte associação com a percepção de fragilidade ungueal (OR = 17,89). A fragilidade foi mais percebida em negras, pardas e atópicas e associou-se com humor depressivo.
