Prevalence of Hpv Infection in the Lekoumou and Niari Departments (Congo Brazzaville)

Abstract

1.1. Objective: to determine the prevalence of HPV infection in women in Lekoumou and Niari departments. 1.2. Patients and Methods: We carried out a descriptive and cross-sectional study over a period of 7 months from January to July 2019 in the department of Lekoumou. 100 women ranging in age from 16 to 73 years old. The variables studied were as follows: age, marital status, level of education, risk factors for the onset of HPV infection, age at first sexual intercourse, number of sexual partners, parity, gesture. The multivariate analysis was done between age, number of level of instruction, parity, age of first sexual intercourse and number of sexual Partners. The statistical analysis and the data processing were carried out by the Excel 2016 software and the graph pad prism version 5 software. The statistical test used was the chi-square test. 1.3. Results: During this study we collected 100 women. The mean age of the patients was 34.6 ± 11.9 with ranges ranging from 16 to 73 years. The most represented age groups were that of 20-29 years (31%) and that of 30-39 years (29%). The most represented level of education was the college level in 53% of cases follow-up of the level of primary education in 25% of cases . Almost ¾ of our study population were married women (74%), single people represented only 22% of the study population. The mean age at first intercourse was 16.4 ± 2.3 with extremes ranging from 12 to 25 years. Almost all of the women (97%) had had their first sexual intercourse before the age of 20. The average number of sexual partners was 5.3 ± 3.2 with extremes ranging from 1 to 15 partners, 53% of women had at least 5 sexual partners. The mean number of pregnancies was 4.9 ± 2.8 with extremes ranging from 0 to 13 pregnancies. Almost half of the women (49%) have carried between 4-7 pregnancies. The mean number of deliveries (parity) was 3.6 ± 2.4 with extremes ranging from 0 to 12 deliveries. 36% of our study population had between 4 and 7 deliveries. Bivariate analysis failed to find a statistically significant difference between age and number of sexual partners, between age of first intercourse and level of education and parity. 1.4. Conclusion: Cervical cancer is a public health problem. Prevalence of infection of HPV is relatively high in our context of low incomes countries. It is important to know this prevalence in order to assure prevention of cervical cancer.
