Background Women with polycystic ovarian syndrome have a high prevalence of metabolic syndrome and type 2 diabetes mellitus. Blacks and Hispanics have a high morbidity and mortality due to cardiovascular disease and diabetes mellitus in the general population. Since metabolic syndrome is a risk factor for development of type 2 diabetes and cardiovascular disease, understanding any racial and ethnic differences in metabolic syndrome amongst women with polycystic ovarian syndrome is important for prevention strategies. However, data regarding racial/ethnic differences in metabolic phenotype amongst women with polycystic ovary syndrome is inconsistent. Objective To determine if there are racial/ethnic differences in insulin resistance, metabolic syndrome and hyperandrogenemia in women with polycystic ovarian syndrome. Study Design Secondary data analysis of a prospective multicenter, double blind controlled clinical trial, the Pregnancy in Polycystic Ovary Syndrome II study, conducted in 11 academic health centers. Data on 702 women with polycystic ovarian syndrome aged 18-40 years who met modified Rotterdam criteria for the syndrome and wished to conceive were included in the study. Women were grouped into racial/ethnic categories Non-Hispanic Whites, non-Hispanic Blacks and Hispanic. The main outcomes were the prevalence of insulin resistance, metabolic syndrome and hyperandrogenemia in the different racial/ethnic groups. Results BMI (35.1 ± 9.8 vs. 35.7 ± 7.9 vs. 36.4 ± 7.9 kg/m2) and waist circumference (106.5 ± 21.6 vs. 104.9 ± 16.4 vs. 108.7 ± 7.3 cm) did not differ significantly between non-Hispanic White, non-Hispanic Black and Hispanic women. Hispanic women with PCOS had a significantly higher prevalence of hirsutism (93.8 vs. 86.8%), abnormal free androgen index (FAI) (75.8 vs. 56.5%), abnormal homeostasis model assessment (HOMA) (52.3 vs. 38.4%) and hyperglycemia (14.8 vs. 6.5%), as well as lower sex hormone binding globulin compared to non-Hispanic Whites. Non-Hispanic Black women had a significantly lower prevalence of metabolic syndrome (24.5 vs. 42.2%) compared with Hispanic women, and lower serum triglyceride levels compared to both Hispanics and non-Hispanic Whites (85.7 ± 37.3 vs. 130.2 ± 57.0 vs. 120.1 ± 60.5 vs. mg/dL, p<0.01), with a markedly lower prevalence of hypertriglyceridemia (5.1 vs. 28.3 vs. 30.5%, p<0.01) compared to the other two groups. Comment Hispanic women with PCOS have the most severe phenotype, both in terms of hyperandrogenism and metabolic criteria. Non-Hispanic Black women have an overall milder polycystic ovarian syndrome phenotype than Hispanics and in some respects, than Non-Hispanic White women.
Context The relationship between reproductive and cardiometabolic aging is unclear. It is unknown if the relationship differs across different clinical populations. Objective To determine whether markers of ovarian reserve are associated with cardiometabolic risk in reproductive aged women with unexplained infertility (UI), polycystic ovary syndrome (PCOS), and regularly cycling women (OVA). Design and setting Cross-sectional data from 8 US-based academic centers. Participants Women aged 25–40 from 3 clinical populations: 870 with UI, 640 with PCOS, and 921 community-based OVA. Main Outcome Measures Multivariable linear regression models were used to relate anti-mullerian hormone (AMH) and antral follicle count with cardiometabolic parameters including body mass index (BMI), waist circumference (WC), fasting glucose and insulin, homeostasis model assessment-insulin resistance (HOMA-IR), lipids, and C-reactive protein. Results In age and study site-adjusted models, AMH inversely related to BMI in the UI and OVA groups (P = 0.02 and P < 0.001). Among women with PCOS, AMH inversely related to BMI (P < 0.001), and also to WC (P < 0.001), fasting insulin (P < 0.01), HOMA-IR (P < 0.01), triglycerides (P = 0.04), and C-reactive protein (P < 0.001) and directly related to higher total (P = 0.02), low-density lipoprotein (P < 0.01), and high-density lipoprotein cholesterol (P < 0.01). In OVA, AMH also varied inversely with WC (P < 0.001), fasting insulin (P = 0.02), and HOMA-IR (P = 0.02). Adjustment for BMI eliminated associations in the OVA group but in PCOS, the relationship of AMH to total (P = 0.03) and low-density lipoprotein cholesterol (P = 0.003) remained. Conclusion Associations observed between AMH and cardiometabolic indices are largely explained by BMI in women with and without PCOS. (J Clin Endocrinol Metab XX: 0-0, 2019)
Objective: To evaluate the quantity and use of embryos cryopreserved at assisted reproductive technology (ART) clinics in the United States from 2004 through 2013 and to characterize trends in ART cycles in which all embryos were cryopreserved. Design: Retrospective analysis.
Objective: To examine the factors associated with increased deoxyribonucleic acid fragmentation index (DFI), evaluate the pregnancy outcomes of men with increased DFI, and compare three independent DFI assays. Design: Secondary analysis. Setting: Nine US-based fertility centers. Patient(s): Infertile men (N ¼ 147) with sperm concentration %15 Â 10 6 /mL, motility %40%, or normal morphology %4% were enrolled. The female partners were ovulatory, %40 years old, and had documented tubal patency. Intervention(s): At a baseline visit, the men provided a semen sample. The couples attempted conception without assistance for 3 months and with ovarian stimulation and intrauterine insemination in the subsequent 3 months. Main Outcome Measure(s): The DFI was analyzed using the sperm chromatin structure assay (SCSA) with increased DFI defined as >30%. The predictors of increased DFI were determined by a multivariable linear regression model. The pregnancy outcomes were compared using the c 2 test. The independent DFI assays (SCSA, deoxynucleotidyl transferase-mediated dUTP nick end labeling, and Comet) were compared with Pearson and Spearman correlations.
STUDY QUESTION What demographic and baseline characteristics are predictive of adherence to reproductive medicine clinical trial protocols, live birth or participation in genetic studies? SUMMARY ANSWER Race, BMI and lower income are associated with likelihood of non-adherent to reproductive medicine clinical trial protocols, while race influences collection of biological samples and non-adherent to study protocols is associated with lower probability of live birth. WHAT IS KNOWN ALREADY Although aspects of adherence to study protocol have previously been evaluated as individual factors in infertile women, the factors that affect overall non-adherent to study protocol have not been previously evaluated. STUDY DESIGN, SIZE, DURATION A secondary data analysis of 1650 participants from two prospective multicenter, double-blind controlled studies was carried out: Pregnancy in Polycystic Ovary Syndrome II (PPCOS II) and Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS). PARTICIPANTS/MATERIALS, SETTING, METHODS The participants were women aged 18–40 years old with either polycystic ovary syndrome (PCOS) with ovulatory dysfunction in combination with either hyperandrogenemia and/or polycystic ovarian morphology (PPCOS II), or regular ovulatory cycles with unexplained infertility (AMIGOS). The study was carried out in 14 clinical sites in the USA. Non-adherence to clinical trial protocol was chosen as the primary outcome for this analysis. To evaluate whether demographic and baseline characteristics were predictive of adherence to study protocols, live birth or participation in blood sampling for DNA and repository, and pregnancy registry, these putative factors were compared between the outcome measures. Logistic regression was used to establish a prediction model using the putative predictors introduced above. MAIN RESULTS AND THE ROLE OF CHANCE Women who self-identified as African American or Asian and those with higher BMI and lower household income were less likely to adhere to protocol. Non-adherence to the study protocol was associated with a lower probability of live birth (odds ratio: 0.180, 95% CI: 0.120, 0.272, P < 0.001). African Americans or Asians were less likely to participate in optional study DNA collection compared to Whites. Participants who were African American or with high annual income or from the Southwest sites or had PCOS were less likely to participate in the blood repository studies. LIMITATIONS, REASONS FOR CAUTION Race and ethnicity were self-reported and such self-classification to strict race and ethnicity may not always be representative of a whole racial or ethnic group. This study included two US multicenter trials and therefore the findings may not be extrapolated to international trials. WIDER IMPLICATIONS OF THE FINDINGS Identification of populations with low participation is an important initial step, as further investigation can develop specific measures to improve adherence to study protocols and participation in biospecimen banking and thereby extend the representativeness of reproductive medicine clinical trial findings.
