Abstract
Objective
To evaluate the associations between dietary fiber intake and ovarian cancer
risk.
Methods
A literature survey was conducted by searching the PubMed, Web of Science,
and Wanfang Med Online databases up to March 1st, 2018. The effect of
dietary fiber intake on ovarian cancer risk was evaluated by calculating
relative risks with 95% confidence intervals (95%CI) using Stata 12.0
software.
Results
A total of 17 articles with 149,177 participants including 7609 ovarian
cancer patients were included in this analysis. The summarized relative risk
for ovarian cancer in participants with the highest compared with the lowest
fiber intake was 0.760 (95%CI=0.702–0.823), with no significant
between-study heterogeneity (I2=12.4%). Subgroup
analysis according to study design demonstrated positive associations in
both cohort studies and case-control studies. Moreover, the results were
consistent among populations from America, Europe, and Asia. No publication
bias was found by Egger’s test or funnel plots.
Conclusion
This meta-analysis concluded that a high intake of dietary fiber could
significantly reduce the risk of ovarian cancer compared with a low fiber
intake.
