BACKGROUND: Despite high prevalence of human papillomavirus (HPV) infection and cervical cancer in Indian women, no study has been done in tribal populations whose socio-sexual lifestyle is different. Therefore, HPV screening has been carried out in pre-adolescent, adolescent and young adult tribal girls using self-collected urine samples.
METHODS: 20-35 ml self-collected midstream urine samples were obtained from a total of 2278 healthy tribal girls (9-25 years) comprising pre-adolescent, adolescent and young adults from three Indian states: Madhya Pradesh, Jharkhand and Chhattisgarh. β-globin positive 2034 samples were employed for HPV detection and genotyping.
RESULTS: The overall prevalence of HPV infection in tribal girls was 12.9% (262/2034). More than 65% (172/262) of them were infected with HR-HPV types of which HPV16 was the most predominant type (54%). Young adult girls aged 18-25 years showed a significantly higher prevalence of HPV infection (19.2%; OR = 3.36; 95% CI 2.97-6.34, P<0.001) as compared to that in adolescent (11.4%; OR = 1.82; 95% CI 1.20-2.76, P<0.01) or pre-adolescent girls (6.6%).
CONCLUSION: This is a first study showing significantly a very high prevalence of HPV infection in adolescent and young adult tribal girls possibly due to different socio-sexual behavior, indicating a serious health concern for Indian tribal women.
