Abstract
Background: Studying human papillomavirus (HPV) genotype concordance between male and female partners and between multiple anatomical sites can help our understanding of HPV epidemiology.
Methods: Heterosexual couples aged 18+ formed within the past 6 months attended visits at 0, 2, 4, 6, 9, and 12 months. They answered questionnaires and provided genital, oral, and anal samples for HPV genotyping. We calculated observed/expected (O/E) concordance (with 95% confidence intervals [CI]) between anatomical sites of HPV genotype-specific infections, across all visits and cumulatively (i.e., ever-positivity). We used mixed-effects logistic regression with random intercepts at the person-level to estimate odds ratios (OR) for concordance and to assess predictors of genital HPV detection and partner concordance.
Results: Within-individual O/E genital/anal concordance was 23.37 (CI: 15.55-38.05) for females and 14.79 (CI: 9.20-43.45) for males, whereas genital/genital O/E concordance between partners was 14.99 (CI: 12.47-18.41). Genital/genital concordance for ever-positivity within couples was substantial: O/E: 10.06 (CI: 8.55-12.12), OR: 70.75 (CI: 43.70-114.56) for females and 67.34 (CI: 41.96-108.06) for males. Significant predictors of genital ever-positivity were one's partner's ever-positivity, OR: 66.2 (CI: 40.96-107.08) in females and 61.53 (CI: 38.19-99.14) in males, and age above the median in females and males, OR: 1.66 (CI: 1.06-2.59) in females and 1.95 (CI: 1.30-2.91) in males. Concordance doubled (OR: 1.96, CI: 1.12-3.46) with occasions of intimacy above the median.
Conclusions: We observed substantial genital/anal concordance within individuals (particularly females) and genital/genital concordance between partners. Certain sociodemographic and behavioral factors influenced concordance.
Impact: Findings shed light on HPV natural history and transmissibility.
期刊介绍:
Cancer Epidemiology, Biomarkers & Prevention publishes original peer-reviewed, population-based research on cancer etiology, prevention, surveillance, and survivorship. The following topics are of special interest: descriptive, analytical, and molecular epidemiology; biomarkers including assay development, validation, and application; chemoprevention and other types of prevention research in the context of descriptive and observational studies; the role of behavioral factors in cancer etiology and prevention; survivorship studies; risk factors; implementation science and cancer care delivery; and the science of cancer health disparities. Besides welcoming manuscripts that address individual subjects in any of the relevant disciplines, CEBP editors encourage the submission of manuscripts with a transdisciplinary approach.
