Takeaway

  • Unhealthy dietary habits are associated with increased odds of high-risk HPV infection (hrHPV).
  • Medium-high adherence to the Mediterranean diet lowers the risk.

Why this matters

  • First report on the association between dietary patterns, hrHPV status, and high-grade cervical intraepithelial neoplasia (CIN+).

Study design

  • Cross-sectional study of 539 women with abnormal Papanicolaou test who completed a Food Frequency Questionnaire.
  • 2 dietary patterns based on dietary habits were:
    • Western: high intake of chips, snacks, dipping sauces, plant oils, processed and red meats, low olive oil intake.
    • Prudent: high intake of legumes, vegetable soups, potatoes, cooked/raw vegetables, and olive oil.
  • Funding: Department of Medical and Surgical Sciences and Advanced Technologies “GF Ingrassia,” University of Catania, Italy.

Key results

  • High and medium adherence to the Mediterranean diet was associated with lower risk for hrHPV (OR, 0.79 [P=.018] and 0.40 [P=.008], respectively).
  • Increased “Western pattern” diet was associated with greater risk for hrHPV (OR, 1.44; P=.036), particularly for women in the third (aOR, 1.77; 95% CI, 1.04-3.54) and fourth quartiles (aOR, 1.97; 95% CI, 1.14-4.18).
  • Women in the third vs first quartile of the “prudent pattern” had lower risk for CIN+ (OR, 0.50; 95% CI, 0.26-0.98).

Limitations

  • Cross-sectional study.
