ABSTRACT
We investigated human papillomavirus (HPV) infection in two female populations from diverse socio-economic strata from the state of Rio de Janeiro and we also investigated the possible co-factors related to infection and the progression to cancer. In Group I, the reference group of this study, 10.7 percent of the patients presented HPV infection, as detected by generic PCR, while in Group II (low socio-demographic conditions) HPV was detected in 31.1 percent of the samples. HPV16 was the most prevalent virus type found in both Groups I and II (5.3 percent and 10 percent, respectively), followed by HPV 18 (1.3 percent and 4.7 percent, respectively). Although only a small sample was analysed, we detected differences among the groups regarding the rates of HPV infection, HPV types, age, ethnicity, familial income, schooling, marital status, parity, tobacco smoking and oral contraceptive use. For Group I, the Papanicolaou test was the most powerful independent factor associated with HPV status, followed by an age of under 30 years old, the number of sexual partners and black ethnicity. Our data are in agreement with the co-factors that are typically described for the developed world. For Group II, the Pap test was also the most relevant variable that was analysed, but the history of other sexually transmitted diseases and the use of alcohol were additional factors that were implicated in infection. These findings point out the need for the development of general and specific strategies for HPV screening of all Brazilian women.
