OBJECTIVE: Disordered eating behaviors may impact the gynecologic health of adolescents through effects on menstrual cycle function and body size; however, few studies have evaluated these associations. This study aimed to prospectively inv…

INTRODUCTION: There is increasing evidence that women who have experienced infertility are at greater risk for several chronic conditions. However, the mechanisms underlying these associations are not clear. Pathophysiology may be illuminat…

BACKGROUND: Endometriosis is a chronic, gynecologic condition in which tissue similar to the lining of the uterus implants throughout the body. Women with endometriosis have a higher prevalence of infertility and a greater risk of early nat…

OBJECTIVE: To study whether incident endometriosis diagnosis, staging, and typology are associated with concurrent elevated serum inflammatory markers interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF- α ). …

Introduction: Endometriosis, affecting 11% of reproductive-aged persons, is characterized by ectopic endometrial tissue and chronic inflammation. Prior research suggests those with endometriosis have higher cardiovascular disease risk, but …

Background: Individuals with endometriosis, a gynecologic condition affecting approximately 11% of people with a uterus, may have an elevated risk for developing cardiovascular disease (CVD) later in life. However, the mechanisms underlying…

BACKGROUND: While plausible mechanisms exist for an association between endometriosis and hypertriglyceridemia, prior studies have shown inconsistent findings, possibly due to the inability to assess endometriosis severity or subtypes. OBJ…

INTRODUCTION: Endometriosis is a chronic inflammatory condition that profoundly affects those who suffer from pelvic pain and abnormal bleeding, resulting in negative impacts on quality of life and associated socioeconomic burdens. The esti…

BACKGROUND: Endometriosis has been linked to cardiometabolic alterations, but whether these associations vary by disease severity or phenotype is unclear. We examined lipid profiles across endometriosis diagnosis, stage, and typology. MATE…

PurposeCirculating levels of sex steroid hormones have previously been associated with premenopausal breast cancer risk. Few studies have considered the association between dietary patterns and premenopausal hormone levels. Our objective wa…

PurposeThere is a consistent relationship with greater ovulation frequency and increased risk of ovarian cancer. However, prior research on infertility, which may be associated with ovulation frequency through multiple mechanisms, and ovari…

ObjectivesDespite biological and environmental plausibility, risk factors for infertility have not yet been studied among female firefighters. In this exploratory analysis, we investigated the burden of infertility among a subset of US fire…

OBJECTIVE: Endometriosis may increase the risk of cardiovascular disease, possibly through a detrimental impact on circulating biomarkers. However, there is a paucity of research on endometriosis and inflammation, lipids, and adipokines at …

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) exposure is widespread and has been linked with gynecologic disease. To our knowledge, no study has measured PFAS in endometrial tissue. METHODS: Eutopic endometrial tissue specimens (…

STUDY QUESTION: How do endometriosis diagnoses and subtypes reported in administrative health data compare with surgically confirmed disease? SUMMARY ANSWER: For endometriosis diagnosis, we observed substantial agreement and high sensitivi…

BACKGROUND: Although endometriosis is a common condition-affecting ∼10% of premenopausal individuals-its etiology is unknown. Diet receives a lot of attention from patients, but studies of the role of diet are limited. Examining dietary pat…

PurposeHysterectomy is associated with subsequent changes in circulating hormone levels, but the evidence of an association for tubal ligation is unclear. We evaluated whether circulating concentrations of androgens and estrogens differ by …

OBJECTIVE: To prospectively assess the effect of endometriosis and uterine fibroids on the long term risk of premature mortality (younger than 70 years). DESIGN: Prospective cohort study SETTING: The Nurses' Health Study II, United States …

(Abstracted from JAMA 2024;332(6):482–489 Ovarian, breast, and endometrial cancers are known to be associated with endometriosis. This study was designed to assess associations between endometriosis and its subtypes with the overall inciden…

IMPORTANCE: Endometriosis has been associated with an increased risk of ovarian cancer; however, the associations between endometriosis subtypes and ovarian cancer histotypes have not been well-described. OBJECTIVE: To evaluate the associa…

OBJECTIVES: To better understand whether history of infertility is associated with anti-Müllerian hormone (AMH) levels later in life, outside of reproduction. METHODS: Among 1,758 premenopausal women in the Nurses' Health Study II with mea…
