Human papillomavirus (HPV) types prevalence in cervical samples of female sex-workers on Curaçao

Sex-workers have an increased risk for high-risk HPV(hrHPV) cervical cancer. On Curaçao, legal and illegal prostitution practice is high and the promiscuous lifestyle is common. We aimed to gain insight in HPV-genotype prevalence in cervical scrapes of female sex workers (FSW) and related risk factors in comparison with women not working in the sex industry.Cervical samples were taken from 76 FSW and 228 non-FSW (NFSW) age matched controls in the period between 2013 and 2015. HPV was detected by GP5+/6+ PCR-EIA followed by genotyping via reverse line-blot.HPV prevalence in FSWs was 25.0% and in NFSWs 29.4% (p = 0.14). NFSW had more often untypable HPV-genotypes (HPV–X:5.3% vs 0.0%; p = 0.042). A trend for statistical difference was observed in HPV prevalence between FSWs from Dominican Republic (42.1%) and FSWs from Colombia (19.2%; p = 0.067). Young age was the only risk factor related to HPV prevalence in FSWs. (Mean age FSW 29.2 y ±7.8 and NFSW 33 y ±6.2) Smoking and drugs consumption were significantly higher among FSW. A significant higher number of women with history of any STD was reported by NFSWs. In addition, >90% of FSW had their previous Pap smear 35% NFSW never had a previous Pap smear (p < 0.001).In conclusion: no significant difference in HPV prevalence is observed between FSW and NFSW. HPV prevalence in FSW was associated with a lower age. During interviews, FSW seemed more aware about prevention strategies, reported less history of STD's and were more updated with cervical cancer screening, compared to NFSWs.
