This study aimed to illustrate the association between cervical cancer with the intake of food groups in women with a history of cervical neoplasia.<span style="font-size:9.0pt"></span></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Methods:</span></i></b> This nested case-control study was conducted in 558 people with a history of cervical intraepithelial neoplasia (CIN), including 279 women with cervical cancers and 279 controls with low-grade squamous intraepithelial lesions (LSIL). A validated food frequency questionnaire (FFQ) was used to assess the intake of food groups.<i><span style="font-size:10.0pt"></span></i></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results:</span></i></b> The intake of fruits and vegetables in the case group was significantly lower than the control group (P=0.001). Low intake of dairy products, vegetables, and fruits was associated with cervical cancer risk (OR=4.67; 95% CI 1.2-9.49, P=0.001; OR=9.75, 95% CI 1.36-19. 51, P=0.001; and OR=4.82, 95% CI 1.09-7.25, P=0.001, respectively). After adjusting for<span lang="EN"> age, family history, age at first menstruation, number of children, history of vaginal infection, and age at first sexual intercourse, the results were still significant. Additional adjustments to BMI did not change the results.</span><b><i><span style="color:blue"></span></i></b></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> <span lang="EN">The results indicate that the risk of cervical cancer can be affected by the intake of certain food groups. Further longitudinal studies are needed to confirm these findings and determine the underlying mechanism of the influence of dietary components on cervical cancer risk.</span><b><i><span style="color:#0033cc"></span></i></b></span></span></span> cervical cancer, cervical intraepithelial neoplasia, dietary intake, food groups 599 606 http://caspjim.com/browse.php?a_code=A-10-2324-1&slc_lang=en&sid=1 Moge Hajiesmaeil MogHajiesmaeil548@yahoo.com 100319475328460037595 100319475328460037595 No Department of Biology and Biotechnology Samaneh Mirzaei Dahka Samanehirzaei478@yahoo.com 100319475328460037596 100319475328460037596 No Student Research Committee, Guilan university of Medical Sciences, Rasht, Iran Ruin Khorami NasrinKho45mi345@yahoo.com 100319475328460037597 100319475328460037597 No Garmsar Islamic Azad university.
