ObjectiveThe aim of this study was to investigate and compare the dietary patterns of Korean women diagnosed withendometrioma or other benign ovarian cysts. MethodsA total of 66 patients, comprising 39 patients who were surgically diagnosed with ovarian endometrioma and27 control patients with other benign ovarian cysts, were included in this case-control study. Trained interviewersidentified and interviewed the case patients and controls on the day before the laparoscopic ovarian surgery, using asemiquantitative food frequency questionnaire developed by the Ministry of Health and Welfare of Korea. Statisticalanalysis was performed using the Wilcoxon sum-rank test for continuous variables and the χ2 test or Fisher’s exact testfor categorical variables. ResultsThe calcium intake from daily food consumption was significantly lower in patients with endometrioma than in thosewith other benign ovarian cysts. The dietary intakes of vitamin D, iron, and zinc were also relatively lower in patientswith endometrioma than in patients with other benign ovarian cysts, although they did not reach the statisticalsignificance threshold. ConclusionThe risk of endometrioma is significantly associated with a lower dietary intake of calcium. Future studies including alarger number of patients on a nationwide scale are urgently required for further clarification.
