Oncogenic HPV Types Infection in Adolescents and University Women from North Portugal : From Self-Sampling to Cancer Prevention

الملخص EN

This study aimed to characterize the HPV infection status in adolescents and young university women in Portugal.

The distribution of HPV genotypes was evaluated by PCR DNA genotyping after self-sampling collection from 435 women of exfoliated cervical cells using a commercial kit.

We observed an overall frequency of HPV infection of 11.5%.

Furthermore, HPV DNA prevalence was 16.6% in those young women that self-declared as sexually active.

The more frequently detected HPV types were 31, 16, 53, and 61.

Statistical analysis identified median age (OR=3.56; P=0.001), the number of lifetime sexual partners (OR=4.50; P<0.001), and years of sexual activity (OR=2.36; P=0.008) as risk factors for HPV acquisition.

Hence, our study revealed that oncogenic HPV infection is common in young asymptomatic women Portuguese women, with a history of 2–5 sexual partners and over 2 year of sexual activity.

Moreover, these results demonstrate that HPV detection performed in self-collected samples may be important to appraise better preventive strategies and to monitorize the influence of vaccination programmes within different populations.
