What the study found
The study found associations between some dominant food patterns and endometriosis in women aged 15 to 45. In particular, patterns high in processed meats, oils, and sugars were linked with higher odds of endometriosis.
Why the authors say this matters
The authors conclude that food patterns high in processed meats, oils, and sugars may increase the risk of endometriosis in women. Endometriosis is described in the abstract as a chronic inflammatory condition, meaning a long-lasting condition involving inflammation.
What the researchers tested
The researchers conducted a case-control study with 180 women, including 60 with endometriosis and 120 without it. Endometriosis was confirmed by ultrasound or laparoscopy, and diet was assessed with a 146-item food frequency questionnaire. They used factor analysis to identify dietary patterns and logistic regression, along with other statistical tests, to examine associations while adjusting for factors such as BMI, menstrual cycle characteristics, physical activity, and education.
What worked and what didn't
Three dominant dietary patterns were identified: one high in red meat, solid oils, high-fat snacks, and processed foods; one featuring vegetables, grains, and coffee; and one including sugar, cereals, and jam. Pattern one and pattern three were significantly associated with increased risk of endometriosis, while pattern two was not reported as significantly associated. Higher energy, lipid, and carbohydrate intake were also significantly associated with endometriosis.
What to keep in mind
This was an observational case-control study, so it can show associations but not prove cause and effect. The abstract does not describe limitations beyond the study design, and the reported confidence interval for one odds ratio appears inconsistent in the abstract as provided.
