About the Project


The YWHS is a prospective study of young (15 to 29 years) women engaged in sex work in Phnom Penh


Aims are to: 1) estimate prevalence and incidence of HIV and STIs including HPV; 2) examine the socio-cultural factors and risks associated with ATS use and; 3) assess rates of completion and adherence to a multi-dose vaccine regimen for the prevention of HPV

Design & Method

Women are followed up at quarterly intervals and asked to complete a structured questionnaire in Khmer and to provide blood forHIV testing, self-collected urine for chlamydia, gonorrhoea and ATS testing, and cervical swabs for human papilloma virus (HPV) testing.  HPV vaccination is offered to eligible participants. As part of the YWHS, trained interviewers also conducted qualitative in-depth interviews to explore social and cultural influences on HIV/STI risk and protective behaviours and ATS use


Data are being analysed and results prepared for publication
