This case-control study investigated the association between alcohol consumption and endometriosis risk among infertile women. The researchers compared 80 women with histologically confirmed endometriosis to 90 controls, analyzing data through multiple logistic regression while adjusting for education, body mass index, and adolescent physical exercise. Although the results indicated higher odds ratios for wine, beer, and spirits intake in women with endometriosis compared to non-drinkers, these associations did not reach statistical significance due to the small sample size. This paper is centrally about endometriosis — specifically examining potential dietary risk factors such as alcohol consumption in an infertile population.

Abstract

Background: Alcohol consumption, a common habit worldwide, may affect estrogen levels. A relation between alcohol intake and endometriosis risk has been suggested. Materials and Methods: Case-control study including 80 infertile women with histologically confirmed endometriosis and 90 women, admitted for a wide spectrum of acute conditions unrelated to known potential risk factors for endometriosis, were interviewed using a structured questionnaire. Potential risk factors for endometriosis were analyzed using unconditional multiple logistic regression, fitted by the method of maximum likelihood. Results: Women with endometriosis were more educated and leaner. They also performed physical exercise during adolescence. The estimated odds ratios (ORs), in comparison with women reporting no alcohol intake, were 1.45 (95% confidence intervals (CIs) 0.76-2.78) for alcohol in general, 1.48 (95% CI 0.76-2.87) for women who drank wine, 1.29 (95% CI 0.65-2.58) for beer, and 1.30 (95% CI 0.56-3.03) for spirits. These findings were confirmed in strata of education, BMI, and leisure physical exercise during adolescence. Conclusions: This analysis, although base on limited number of subjects, may offer some information about the suggested relation between endometriosis and alcohol intake.
