BACKGROUND: Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES: To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS: Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS: 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age--all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (p<0.001). DISCUSSION: The prevalence of acne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-p<0.001), were more likely to have non-comedonal acne. CONCLUSION: This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

BACKGROUND/OBJECTIVE: Acne vulgaris exhibits a worldwide prevalence of up to 95% among adolescents. On the other hand, Down syndrome is an autosomal chromosomal disorder with associated dermatoses and a tendency to obesity. There are no data on its association with acne. Our aim was to detect the prevalence of acne, its forms and associated factors in Down syndrome. METHOD: A cross-sectional study including 89 subjects aged 10-28 years from Associação de Pais e Amigos dos Excepcionais-São Paulo to verify acne, metabolic and hormonal disorders by interview, clinical and laboratory examinations. RESULTS: We evaluated 49 (55%) males and 40 (45%) females. A weak agreement between self-estimation for acne and examination result was detected. The overall prevalence of acne was 70.8%: 83.7% in males and 55% in females. The prevalence of acne in the age groups 10-17 and 18-28 was 62 and 78.7%, respectively. Facial comedonal acne was mostly detected. The prevalence of obesity was 40%, that of metabolic disorders 7% and that of hyperandrogenism (in females) 15%. Except for gender, no other factor evaluated correlated with acne. CONCLUSION: A low prevalence of acne in Down syndrome, a predominance in males aged 18-28 and a facial comedonal form were detected. An association with obesity, metabolic disorders or hyperandrogenemia was not assessed.
