Cervical cancer (CC) is the second most frequent malignancy. Infections with the human papillomavirus have a crucial role in the Pathology of CC. The association of nutrient and dietary pattern with CC have been reported in few studies. This study was conducted to evaluate the relationship between dietary patterns and CC situations in the Iranian population. This is a case-control study in which totally 260 controls and 132 patients aged 30-79 were included as control, and case groups. Dietary data were evaluated by 147-items semi-quantitative food frequency questionnaire. Multivariate logistic regression was used to estimate the relationship between dietary patterns and risk of cervical cancer. Statistical analysis investigated two dietary patterns (healthy and unhealthy). Two dietary patterns covered 17.76% of total variance of dietary intake. Higher adherence of the unhealthy dietary pattern was associated with increased risk of CC (OR= 2.23, 95% CI= 1.77-4.24); however, there was no association between healthy dietary pattern and CC (OR= 1.91, 95% CI= 0.90-3.20). Our results indicate that unhealthy dietary pattern is significantly associated with CC.
