Abstract

Background Modifiable risk factors such as diet may be important in both the etiology and progression of endometriosis as well as the prevalence of pain symptoms and infertility associated with this condition. In adults, higher intake of dairy has been associated with a lower risk of endometriosis diagnosis. There is currently no literature on whether dairy intake during adolescence, a potentially critical window of exposure, influences endometriosis risk.Objective The objectige of the study was to evaluate the association between consumption of dairy foods in adolescence and the risk of laparoscopically confirmed endometriosis.Study design This was a prospective cohort study, the Nurses' Health Study II, which has prospectively collected data since 1989. In 1998, when participants were aged 34-51 years, they completed a 124 item food frequency questionnaire about their high school diet. Cases were defined as those who self-reported laparoscopically confirmed endometriosis. Cox proportional hazard models were used to calculate hazard ratios and 95% confidence intervals for the association between dairy foods and laparoscopically confirmed endometriosis.Results Among women who completed the questionnaire about their high school diet in 1998, 581 cases of laparoscopically confirmed endometriosis were diagnosed among 32,868 premenopausal women from 1998 to 2013. Women who consumed more than 4 servings per day of dairy foods during adolescence had a 32% lower risk of laparoscopically confirmed endometriosis during adulthood (95% confidence interval, 0.47-0.96; P trend = .04) compared with women consuming 1 or fewer servings per day. The association was similar for low-fat and high-fat dairy foods. Yogurt and ice cream consumption, specifically, were associated with a lower risk of endometriosis. Those who consumed 2 or more servings of yogurt per week as an adolescent had a 29% lower risk of endometriosis diagnosis (95% confidence interval, 0.52-0.97; P trend = .02) compared with those consuming less than 1 serving per week. In addition, women who consumed 1 or more servings per day of ice cream per day during adolescence had a 38% lower risk of endometriosis diagnosis (95% confidence interval, 0.40-0.94; P trend = .20) compared with those consuming less than 1 serving per week.Conclusion Our findings suggest that dairy consumption, specifically yogurt and ice cream intake, in adolescence may reduce the risk of subsequent endometriosis diagnosis. Future studies in adolescent populations are needed to confirm these results.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
