Avaliação clínica e epidemiológica do papilomavírus humano em mulheres idosas em unidades de saúde em Belém –Pará -Brasil

Abstract

Aging is a real phenomenon that brings individual and social changes. Among these current modifications is the permanence of the elderly population in the field of sexual activity. Once this event was particularly the young, the elderly today and are sexually active still increasingly exposed to sexually transmitted diseases (STDs), including infection with the human papillomavirus -HPV, not to adopt safe habits such as condom use. The STD rates in the elderly are of concern when associated with increasing number of cervical cancer in this population. The study aimed to evaluate clinically and epidemiologically HPV in older women to health facilities in Belém / PA. It is a cross-sectional, analytical and quantitative study. Information was collected through clinical and epidemiological questionnaire containing variables on first sexual intercourse, sexual partners, alcohol consumption and smoking habits, etc. Cells of the uterine cervix for performing Pap smear, DNA extraction and detection of HPV DNA were collected. The HPV detection was performed by PCR and subtyping of the real-time PCR. The collections are given after approval of the Center for Tropical Medicine / UFPA Research Ethics Committee under the number 401.991 and analyzed by means of the construction of the database and the Chi-square and Fisher exact tests applied level of significance accepted of α ≤ 0.05. For data analysis, counted with 159 samples of older, averaged 67.98 years of age, widows and with incomplete primary education most. Registered a 6.28% prevalence of HPV infection in these elderly surveyed, there was a significant relationship between infection with multiple partners (p≤0,006) and the habit of smoking in the life (p≤0,03) . Another important fact is older in sexual activity as a higher prevalence of HPV (14.28%) than those without activity (2.72%). Added the event of an elderly infected with viruses having a subtype of high oncogenic risk (HPV16), in addition to all older received cytology within the normal range. It is concluded that despite the prevalence is decreasing in this present age, the elderly are exposed to risk factors that may contribute to increased rates of cervical cancer, highlighting the importance of this research and the constant screening in these women.
