Abstract Diet plausibly has a role in the aetiology of endometriosis through effects on steroid hormone levels; however, few published studies have examined the diet and endometriosis risk.

We evaluated dietary risk factors for endometriosis in a population-based case—control study. Cases were Group Health GH enrollees aged 18—49 years with newly diagnosed, surgically confirmed endometriosis between and Controls were randomly selected age-matched female GH enrollees without a history of endometriosis.

OR of endometriosis risk associated with dietary exposures were estimated using unconditional logistic regression and adjusted for identified covariates. Increased total fat consumption was associated with decreased endometriosis risk fourth quartile v.

The present study suggests that specific dietary components may be associated with endometriosis risk. Case—control studies, Population-based studies, Diet, Endometriosis Endometriosis is a gynaecological disorder characterised by the presence of functioning endometrial glands and stroma outside the uterus.

Symptoms associated with endometriosis include severe menstrual pain, excessive menstrual bleeding, chronic and severe pelvic pain, dyspareunia and subfertility. Increased exposure to oestrogens is a common link among several known risk factors for endometriosis.

Local oestrogen production coupled with circulating oestrogen stimulates the proliferation of ectopic endometrial tissue potentially leading to endometriosis 23. Menarche at early age, shorter menstrual cycle length, nulliparity and greater height are all risk factors for endometriosis that are also associated with increased levels of circulating oestrogen concentrations 4 — 8.

The relationship between diet and endometriosis risk is not well characterised.

Diet may have a role in the aetiology of endometriosis through its influence on steroid hormone levels, among other potential mechanisms.

Some observational studies have shown that plant-based diets and diets high in fibre increase oestrogen excretion and decrease concentrations of bioavailable oestrogen, and thus may lower endometriosis risk 9 Additionally, high-fat diets have been associated with increased serum oestrone, oestrone sulphate and oestradiol levels in premenopausal women 911suggesting that diets low in fat and high in fibre may modify endometriosis risk by altering steroid hormone metabolism.

The few published reports evaluating dietary risk factors for endometriosis have been somewhat contradictory. In the first of two case—control studies of endometriosis and specific foods published to date, increased consumption of ham, beef and red meat was associated with increased endometriosis risk in women visiting gynaecology clinics in northern Italy Conversely, in that study, green vegetable, fresh fruit and oil were all associated with decreased risk In the second study, a Belgian clinic-based case—control study, butter was marginally associated with an increased risk of peritoneal endometriosis Recently, a large US cohort study evaluated dietary fat consumption and endometriosis risk using 12 years of prospectively collected data The authors of that study reported that total dietary fat intake was not associated with endometriosis risk, but increased long-chain n-3 fatty acid consumption was associated with decreased risk of endometriosis and trans-fat intake was associated with increased risk of endometriosis The purpose of this analysis was to further investigate the role of diet — assessing both nutrients and a wide variety of food groups — as a risk factor for endometriosis in a population-based case—control study of US women.

Women who did not speak English or who reported a hysterectomy or bilateral oophorectomy upon initial telephone eligibility screening were excluded from the participation.

The present study was conducted according to the guidelines established in the Declaration of Helsinki, and all procedures involving human subjects were approved by the GH Institutional Review Board.A nested case-control study in the Swedish Västerbotten intervention programme (a prospective population-based study) investigated the effect of diet, looking at food groups, macronutrients and dietary pattern, including the Mediterranean diet.

This study comprised incident RA cases and matched controls and did not find an. Background: International comparisons and case-control studies have suggested a positive relation between dietary fat intake and breast cancer risk, but prospective studies, most of them involving.

Most of the participants in both groups had received a low level of education (case = %; control = %) and had a low family income (case = %; control = %). Of the total in both the groups, % of patients in the case group were smokers compared with % in the control group.

Therefore, in this case-control study, we aimed to explore the dose-response relationship between dietary calcium intake and colorectal cancer risk in the Korean population, where national average calcium intake level is relatively lower than western countries.

One case-control study,40 after adjustment for smoking, found that intake of β-carotene was associated with a 40% greater reduced risk of colorectal adenomas than consumption of other dietary carotenoids.
