OBJETIVO: descrever a idade de início da atividade sexual (sexarca) e a sua associação com a idade das mulheres com a infecção por papilomavírus humano (HPV) e com as alterações citológicas no exame de papanicolaou. MÉTODOS: mulheres da população geral foram recrutadas para participar de um estudo de rastreamento de câncer cervical e lesões pré-malignas. Após a aplicação de questionário comportamental, foram submetidas ao rastreamento com gia cervical e teste para DNA de HPV de alto risco, por meio de Captura Híbrida 2. Este projeto faz parte do Latin American Screening Study, que envolve mulheres do Brasil e da Argentina, e os dados aqui apresentados referem-se aos centros brasileiros nas cidades de Porto Alegre, São Paulo e Campinas. RESULTADOS: de 8.649 mulheres entrevistadas, 8.641 relataram atividade sexual prévia e foram incluídas na análise. A média de idade no momento da entrevista foi de 38,1±11,04 anos, com início da atividade sexual em média aos 18,5±4,0 anos. Identificamos que a idade do início da atividade sexual aumenta de acordo com o aumento da faixa etária no momento da entrevista, isto é, mulheres mais novas relataram sexarca mais precoce que mulheres mais velhas (p ou = ASC-US (6,7%) do que mulheres com sexarca em idade maior que a média (4,3%) - OR=1,6 (IC95%=1,3-2,0; pPURPOSE: to investigate women’s age at their first sexual intercourse and its correlation with their present age, human papillomavirus (HPV) infection and cytological abnormalities at Pap smear. METHODS: women from the general population were invited to be screened for cervical cancer and pre-malignant lesions. After answering a behavior questionnaire, they were submitted to screening with cervical cytology and high-risk HPV testing with Hybrid Capture 2 (HC2). This report is part of the Latin American Screening (LAMS) study, that comprises centers from Brazil and Argentina, and the data presented herein refer to the Brazilian women evaluated at the cities of Porto Alegre, São Paulo and Campinas. RESULTS: from 8,649 women that answered the questionnaire, 8,641 reported previous sexual activity and were included in this analysis. The mean age at the interview was 38.1±11.0 years and the mean age at the first sexual intercourse was 18.5±4.0 years. The age at the first sexual intercourse increased along with the age at the interview, i.e., younger women reported they had begun their sexual life earlier than older women (p or = ASC-US (6.7%) than the women with the first sexual intercourse at ages above the mean (4.3%) - OR 1.6 (IC95% 1.3-2.;p<0.001). CONCLUSIONS: the high-risk HPV infection and cytological abnormalities identified during the asymptomatic population screening were significantly associated to the women’s age at the first sexual intercourse. Additionally, we have also identified that the women’s age at the first sexual intercourse has decreased during the last decades, suggesting an important contribution to the increase of HPV infection and the subsequent cervical lesions.
