Description of intervention(s) / exposure
All women aged 20-24 years attending colposcopy following abnormal screening cytology in participating centres will be invited to participate in the study. Consenting women will have a cytology sample taken from the cervix as part of their colposcopy. High risk HPV testing and extended genotyping will be performed by the BD viper assay performed by Canterbury Health Laboratory or partial genotyping (HPV 16, HPV 18, other high risk HPV, or high risk HPV not detected) using the HPV assay routinely used by that laboratory. This will be a one-off test and there will be no further follow-up specific to the study.

Comparator / control treatment
The HPV type prevalence in women with high grade cervical abnormalities (CIN2 or 3) will be compared with historical data (August 2009 to February 2011) (Simonella LM, Lewis H, Smith M, Neal H, Bromhead C, Canfell K. Type-specific oncogenic human papillomavirus infection in high grade cervical disease in New Zealand. BMC Infect Dis 2013;13:114).

Outcomes
Primary outcome [1] 307115 0
The prevalence of high risk vaccine-type human papillomavirus genotypes (either HPV 16 or 18 or both) in young women (aged 20-24 years) with high grade histology (e.g., CIN2 or CIN3).
Timepoint [1] 307115 0
HPV genotype analysis for each participant will be undertaken on the cytology taken at the initial colposcopic assessment. HPV genotype prevalence will be assessed once all participants have been recruited - approximately 12 months after first enrolment.
Secondary outcome [1] 350734 0
HPV vaccination status as assessed by data-linkage to the National Immunisation Register.
Timepoint [1] 350734 0
HPV vaccination status for each participant will be requested following their initial colposcopic assessment. Analysis of the overall group will be assessed once all participants have been recruited - approximately 12 months after first enrolment.
Secondary outcome [2] 350735 0
The prevalence of high risk vaccine-type human papillomavirus genotypes (either HPV 16 or 18 or both) compared with (1) other high risk non-vaccine genotypes and (2) co-infection with vaccine-type HPV genotypes and high risk non-vaccine genotypes, in young women (aged 20-24 years) with LOW grade histology (e.g., CIN1)..
Timepoint [2] 350735 0
HPV genotype analysis for each participant will be undertaken on the cytology taken at the initial colposcopic assessment. HPV genotype prevalence will be assessed once all participants have been recruited - approximately 12 months after first enrolment.

Statistical methods / analysis
The analysis of data will be largely descriptive. A two-proportion z-test will be used to determine whether there is a difference in the proportion of women with HPV 16 or 18 positive cytology in this sample compared with historical data.
