Prevalence and determinants of human papillomavirus (HPV) infection in Inuit women of Nunavik, Quebec

Objectives: To study the prevalence and determinants of human papillomavirus (HPV) infection among Inuit women in Nunavik, Quebec. Methods: We recruited a cohort of Inuit women seeking routine care and living in communities in Nunavik. Baseline demographic and lifestyle data was collected and cervic...

Methods: We recruited a cohort of Inuit women seeking routine care and living in communities in Nunavik. Baseline demographic and lifestyle data was collected and cervical specimens were tested for HPV-DNA using the PGMY-Line blot assay. Results: Overall and high-risk (HR) HPV prevalence were 28.9% and 20.4%, respectively. Co-infections were observed in 40% of HPV-positive subjects. The most common HPV type was HPV-16; other prevalent HR types included HPV-31, HPV-52, and HPV-58. The most prevalent papillomavirus species were alpha-9 and alpha-3. In multivariate logistic regression, age (OR: 0.95; 95% CI: 0.93-0.98) and ten or more lifetime sexual partners (OR: 2.25; 95% CI: 1.41-3.60) were associated with HR-HPV infection. Conclusions: HPV prevalence is elevated when compared to most Canadian populations. Age and markers of sexual activity appear to be risk factors for HR-HPV infection. Objectif: Déterminer la prévalence et les déterminants du VPH chez les femmes inuites du Nunavik, Québec. Méthode: Nous avons recruté une cohorte de femmes vivant au Nunavik. Des données démographiques et reliées au mode de vie ont été récoltées. Des échantillons de cellules du col de l'utérus ont été analysés à l'aide du PGMY-Line blot assay afin de détecter de l'ADN-VPH. Résultats: La prévalence du VPH et du VPH-HR était respectivement de 28.9% et 20.4%. Les types de VPH-HR les plus répandus étaient VPH-16, VPH-31, VPH-52 et VPH-58. Une analyse de régression logistique multivariée a révélé que l'âge (RC: 0.95; 95% CI: 0.93-0.98) et avoir dix partenaires sexuels ou plus au cours d'une vie (RC: 2.25; CI: 1.41-3.60) sont associés à l'infection au VPH-HR. Conclusion: La prévalence du VPH est élevée comparée à la majorité des populations canadiennes. L'âge et des marqueurs d'activité sexuelle sont des facteurs de risque pour l'infection au VPH-HR.
