INTRODUCTION: Obesity is known to increase susceptibility to certain infections in men. It is unclear whether obesity increases women's risk for human papillomavirus (HPV) infection. METHODS: In a prospective cohort of 696 perimenopausal women enrolled in 2008-2012, we sought to determine whether obesity predicted incident HPV detection or nondetection. Obesity was defined as body mass index (BMI) ≥ 30 kg/m(2). RESULTS: Baseline any type HPV prevalence was comparable between obese and nonobese women (18.7% vs 19.1%; P > .05). Over a median follow-up period of 17.9 months (interquartile range: 12.1-24.5), 187 new HPV detections occurred among 123 women, 60 of whom subsequently lost 76 detectable infections. When compared with nonobese participants, obese women had a similar rate of new HPV detection (7.1 vs 7.8 infections per 1000 infection-years; P > .05) or loss of detection (100.3 vs 85.8 infections per 100 infection-years; P > .05). Similar results were found after adjusting for age, menopausal status, smoking habit, and sexual exposure history. CONCLUSIONS: Results from the current analysis suggest little effect of obesity on HPV detection and loss of detection in mid-adult women. More research is needed to determine whether adipokines or cytokines better capture the potential immune modulating effects of obesity on HPV infection.
