SCHMITT, Juliano Vilaverde; MASUDA, Paula Yoshiko and MIOT, Hélio Amante. Acne in women: clinical patterns in different age-groups. An. Bras. Dermatol. [online]. 2009, vol.84, n.4, pp.349-354. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962009000400005.
BACKGROUND: Acne is a frequent skin disease that occurs in both sexes and all age-groups. Women present several clinical disease patterns; moreover, persistence after adolescence is common. OBJECTIVE: To analyze clinical and epidemiological characteristics associated with different age-groups affected by acne in women. METHODS: Cross-sectional study involving female patients diagnosed with acne, at a general dermatology outpatient clinic. Variables related to disease and patients were assessed through a standardized questionnaire. RESULTS: One hundred and three women were assessed. The average age of patients at the time of the consultation was 21.7 ± 7.3 years. Two groups were defined (cut-off age of 21 years), with means of 15.8 ± 2.3 and 28.0 ± 5.1 years. There was correlation between disease duration and current age (R=0.7). There were group differences among frequencies of covariables: combined oral contraceptive (OR=48.1), lesions located on upper chest (OR=11.6), lesions on upper dorsum (OR=0.2), predominance on upper half of face (OR=0.1) and age at disease onset (OR=1.8). Among adult women, 80% reported acne onset before 20 years of age. CONCLUSION: Chronologic and topographic patterns of female acne in different age-groups were defined, reinforcing the importance of an individualized diagnostic and therapeutic approach.
