Background:
Previous studies provided inconsistent results regarding the association between inflammatory bowel disease (IBD) and risk of abnormalities of uterine cervix. The study aimed to make a meta-analysis to evaluate the association between IBD and risk of abnormalities of uterine cervix.
Methods:
Articles published until April 2021 and regarding the association between IBD and risk of abnormalities of uterine cervix were searched in the following databases: PubMed, Web of Science, EMBASE, Medline, and Google Scholar. Odds ratios (ORs) from case-control studies and relative risks (RRs) from cohort studies with their 95% confidence intervals (CIs) were computed to generate a pooled effect size and 95% CI using STATA 12.0 software.
Results:
The present study finally included seven cohort studies (including 94 144 IBD patients and 53 661 004 HC) and four case-control studies (including 20 267 cases and 60 034 matched controls). The meta-analysis indicated a positive association between IBD and risk of abnormalities of uterine cervix with a random-effects model (OR/RR = 2.46, 95% CI 1.55-3.91, I2 = 91.8%, p < 0.001). However, no significant association between IBD and risk of cervical cancer was showed in the study with a random-effects model (OR/RR = 1.54, 95% CI 0.83-2.85, I2 = 82.2%, p < 0.001).
Conclusion:
In conclusion, IBD is associated with a 146% higher risk of abnormalities of uterine cervix. However, the study demonstrated no significant association between IBD and risk of cervical cancer. Thus, a conventional screening for abnormalities of uterine cervix is essential for IBD patients.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
