Resumen
This study assessed the level of knowledge, attitude and practice of Pap smear and
human papillomavirus (HPV), in addition to analyzing the prevalence of genital HPV
infection, Herpes Simplex Type 2 (HSV-2) and Chlamydia trachomatis in teenagers.
The study consisted of two approaches, one based only on interviews conducted
with adolescents enrolled in public schools or in public health facilities in the city of
Natal. The other approach involved only a group of 132 adolescents enrolled among
those admitted to two health units in Natal-RN. This second group of participants
two specimens were collected for laboratory analysis: one was directed to prepare
the blade for the Pap test, and other processed for DNA extraction for molecular
analysis, focusing on the detection of HPV, HSV-2 and C . trachomatis. The
presence of DNA of the three pathogens was investigated by the technique of
polymerase chain reaction (PCR). The presence of each of the three pathogens was
analyzed in terms of socio-demographic characteristics, as well as sexual and
reproductive activity to identify risk factors for infection and development of lesions
of the uterine cervix. The results show that the adolescents in this study had levels
of knowledge and attitude very low, both in relation to cytology to HPV as though
they have made a reasonable percentage of adequate practice exam and
prevention of HPV infection. The overall prevalence of HPV infection was 54.5% and
48.2% in adolescents with normal cytology and 86.4% in those with abnormal
cytology. We observed a higher proportion of cases of infection in the age group of
18 to 21. The prevalence of HPV infection was slightly higher among pregnant
teenagers. The overall prevalence of HSV-2 infection was 13.6% and 11.8% in
women with normal cytology and 22.7% in those with abnormal cytology. A higher
proportion of cases of infection was found in the age group from 14 to 17, with a
slightly higher prevalence among pregnant women. The C. trachomatis was found
with an overall prevalence of 19.7% and 21.8% in adolescents with normal cytology
and 9.1% in those with abnormal cytology. The prevailing rate was highest in the
age group 18 to 21 years and in nonpregnant
