Human papillomavirus and cervical neoplasia among female sex workers in Madagascar.

Abstract

INTRODUCTION: Human papillomavirus (HPV) prevalence and type distribution were estimated among 90 female sex workers (FSWs) aged 18 to 58 years in Antananarivo, Madagascar. METHODS: A total of 90 FSWs aged 18 to 58 years in Antananarivo, Madagascar, were included in this study. Information on sexual and behavioral characteristics was obtained via a questionnaire. Exfoliated cervical cell specimens were collected for conventional cytologic examination and HPV DNA testing by polymerase chain reaction. The prevalence rates of HPV DNA and their corresponding 95% confidence intervals were stratified into the following 3 age groups: younger than 25, 25 to 34, and 35 years or older. To assess the association between HPV DNA positivity and sociodemographic and sexual behavioral factors, age-adjusted odds ratios and 95% confidence intervals were calculated using unconditional logistic regression. RESULTS: The HPV prevalence in exfoliated cervical cell specimens was 36.7%. The most common HPV types found were HPV-52 (11.1%), HPV-31 and -39 (each at 5.6%), and HPV-16 and -83 (each at 3.3%). The prevalence of low-grade squamous intraepithelial lesions was 3.3%, and that of atypical squamous cells of undetermined significance was 18.9%. No high-grade lesion was found. Although associations were imprecise, the HPV prevalence was higher among women who reported younger age at the first intercourse, contraceptive use, a history of cervical lesions, and no history of condom use. DISCUSSION: The prevalence rates of HPV and cervical lesions among FSWs in Madagascar appear higher than among FSW populations from other African countries with a relatively higher population-based prevalence of human immunodeficiency virus infection.
