Abstract
The purpose of this paper is to review male-female differences in the incidence and prevalence of diabetes and diabetic retinopathy. These differences will be established primarily through results from our present research and a review of related literature. Previously, we have demonstrated that neuroretinal dysfunction can be used to predict the location of future retinopathy up to three years before it is manifest. Our current research suggests that, for type 2 diabetes, the normal differences in neuroretinal function between nondiabetic males and females under 50 years of age are altered in patients with type 2 diabetes. Furthermore, local neuroretinal function in type 2 diabetes is more abnormal in adult males compared with adult females. The literature also suggests that there are male-female differences in the occurrence of diabetes. In adolescence, the incidence of type 1 diabetes is greater in males, whereas in type 2 diabetes, the incidence is greater in females. This excess of females in type 2 diabetes shifts to a more equal incidence between the two sexes in adults. In addition, advanced retinopathy in type 1 diabetes appears to be more common in males, and the presence and severity of diabetic retinopathy at the time of diagnosis in type 2 diabetes appears to be more associated with male sex. Although the reasons for male-female differences identified in this review are unknown, sex appears to be a significant factor in certain aspects of diabetes incidence and diabetic retinopathy.

Abstract
We examined racial/ethnic disparities in maternal morbidities (MM) and the number of MM during labor and delivery among hospital discharges in Wisconsin. We conducted a retrospective cohort study of hospital discharge data for 206,428 pregnant women aged 13-53 years using 2005-2007 Healthcare Cost and Utilization Project State Inpatient Dataset (HCUP-SID) for Wisconsin. After adjustments for covariates, MM (preterm labor, antepartum and postpartum hemorrhage, hypertension in pregnancy, gestational diabetes, membrane-related disorders, infections and 3rd and 4th perineal lacerations) were examined using logistic regression models, and number of MM (0, 1, 2, >2 MM) were examined using multivariable ordered logistic regressions with partial proportional odds models. African-Americans had significantly higher likelihood of infections (OR = 1.74; 95% CI 1.60-1.89), preterm labor (OR = 1.42; 1.33-1.50), antepartum hemorrhage (OR = 1.63; 1.44-1.83), and hypertension complicating pregnancy (OR = 1.39; 1.31-1.48) compared to Whites. Hispanics, Asian/Pacific Islanders, and Native Americans had significantly higher likelihood of infections, postpartum hemorrhage, and gestational diabetes than Whites. Major perineal lacerations were significantly higher among Asian/Pacific Islanders (OR = 1.53; 1.34-1.75). All minority racial/ethnic groups, except Asians, had significantly higher likelihood of having 0 versus 1, 2 or >2 MM, 0 or 1 versus 2 or >2 MM, and 0, 1 or 2 versus >2 MM than white women. Findings show significant racial/ethnic disparities in MM, and suggest the need for better screening, management, and timely referral of these conditions, particularly among racial/ethnic women. Disparities in MM may be contributing to the high infant mortality and adverse birth outcomes among different racial/ethnic groups in Wisconsin.

Abstract
BACKGROUND Data about the immigrant population living in Spain, their lifestyle habits, and risk factors for gestational diabetes mellitus (GDM) are limited. Thus, the aim of the present study was to describe risk factors for the onset of GDM, the evolution of gestation and delivery, and newborns of Hispanic women living in Spain compared with those of Spanish women. METHODS A semiquantitative questionnaire regarding lifestyle habits was administered to 459 pregnant women (115 Hispanic) with a positive O'Sullivan test (24-28 weeks gestation) between 1 April 2007 and 31 March 2008. Information was collected regarding gestation, delivery, and the newborn. RESULTS The prevalence of GDM increased with mother's age, pregestational overweight/obesity, and multiparity. In addition, GDM was associated with lower pregestational fiber and a lower intake of low glycaemic index foods in Hispanic women. The odds ratios (OR) for the total population were 2.53 (95% confidence interval [CI] 1.28-5.01) for overweight, 3.68 (95% CI 1.72-7.90) for obesity, 3.83 (95% 2.03-7.23) for age ≥35 years, and 1.64 (95% CI 1.02-3.01) for multiparity. Newborns from the Hispanic population were significantly heavier than newborns from Spanish women and the rate of Caesarean delivery was significantly higher in the Hispanic population with GDM compared with those without GDM. CONCLUSIONS The immigrant Hispanic population living in Spain trends to acquire the same risk factors associated with lifestyle to the indigenous population. Preventive strategies must stress increased physical activity and fiber intake, decreased intake of sweetened beverages, and an effective reduction in body weight before pregnancy.

Abstract
OBJECTIVE The aim was to provide a scholarly review of the published literature on biological, clinical, and nonclinical contributors to race/ethnic and sex disparities in endocrine disorders and to identify current gaps in knowledge as a focus for future research needs. PARTICIPANTS IN DEVELOPMENT OF SCIENTIFIC STATEMENT: The Endocrine Society's Scientific Statement Task Force (SSTF) selected the leader of the statement development group (S.H.G.). She selected an eight-member writing group with expertise in endocrinology and health disparities, which was approved by the Society. All discussions regarding the scientific statement content occurred via teleconference or written correspondence. No funding was provided to any expert or peer reviewer, and all participants volunteered their time to prepare this Scientific Statement. EVIDENCE The primary sources of data on global disease prevalence are from the World Health Organization. A comprehensive literature search of PubMed identified U.S. population-based studies. Search strategies combining Medical Subject Headings terms and keyword terms and phrases defined two concepts: 1) racial, ethnic, and sex differences including specific populations; and 2) the specific endocrine disorder or condition. The search identified systematic reviews, meta-analyses, large cohort and population-based studies, and original studies focusing on the prevalence and determinants of disparities in endocrine disorders. consensus process: The writing group focused on population differences in the highly prevalent endocrine diseases of type 2 diabetes mellitus and related conditions (prediabetes and diabetic complications), gestational diabetes, metabolic syndrome with a focus on obesity and dyslipidemia, thyroid disorders, osteoporosis, and vitamin D deficiency. Authors reviewed and synthesized evidence in their areas of expertise. The final statement incorporated responses to several levels of review: 1) comments of the SSTF and the Advocacy and Public Outreach Core Committee; and 2) suggestions offered by the Council and members of The Endocrine Society. CONCLUSIONS Several themes emerged in the statement, including a need for basic science, population-based, translational and health services studies to explore underlying mechanisms contributing to endocrine health disparities. Compared to non-Hispanic whites, non-Hispanic blacks have worse outcomes and higher mortality from certain disorders despite having a lower (e.g. macrovascular complications of diabetes mellitus and osteoporotic fractures) or similar (e.g. thyroid cancer) incidence of these disorders. Obesity is an important contributor to diabetes risk in minority populations and to sex disparities in thyroid cancer, suggesting that population interventions targeting weight loss may favorably impact a number of endocrine disorders. There are important implications regarding the definition of obesity in different race/ethnic groups, including potential underestimation of disease risk in Asian-Americans and overestimation in non-Hispanic black women. Ethnic-specific cut-points for central obesity should be determined so that clinicians can adequately assess metabolic risk. There is little evidence that genetic differences contribute significantly to race/ethnic disparities in the endocrine disorders examined. Multilevel interventions have reduced disparities in diabetes care, and these successes can be modeled to design similar interventions for other endocrine diseases.

Abstract
Background. Medical nutritional therapy is the most important method for normalizing glucose levels in pregnancy. In this setting, there is a new problem to consider relating to migrants, their personal food preferences, and ethnic, cultural, and religious aspects of their diet. We compared maternal and fetal outcomes between two multiethnic groups of pregnant women, one adopting a food plan that included dishes typical of the foreign women's original countries (the "ethnic meal plan" group), while the other group adopted a standard meal plan. Findings. To develop the meal plan, each dish chosen by the women was broken down into its principal ingredients. The quantity of each food was given in tablespoons, teaspoons, slices, and cups, and there were photographs of the complete dish. The group treated with the ethnic meal plan achieved a better metabolic control at the end of the pregnancy and a lower weight gain (though the difference was not statistically significant). As for fetal outcome, the group on the ethnic meal plan had babies with a lower birth weight and there were no cases of macrosomia or LGA babies. Conclusions. This preliminary study indicates the positive effect of an ethnic approach to diet on the outcome of pregnancy.

Abstract
Recent studies show adverse outcomes of pregnancy among immigrant women from countries with high diabetes rates. We compared maternal and fetal outcomes in immigrant and Italian women with gestational diabetes mellitus (GDM) followed up at our center. Maternal characteristics considered were age, pre-pregnancy body mass index (BMI), HbA1c, frequency of insulin treatment, timing and mode of delivery, and hypertensive disorders; and, for fetal outcome, infants large or small for gestational age, and fetal complications. Pre-pregnancy BMI and HbA1c were higher in immigrant GDM women than in Italians, and more of them were on insulin. No differences in maternal outcome emerged between the two groups. More large for gestational age (LGA) babies were born to immigrant women than to Italians, but no other differences emerged. Apart from newborn LGA, maternal and fetal outcomes were comparable in our immigrant and Italian GDM women. Immigrant GDM women have favourable outcomes if given access to health care and language and cultural barriers are removed.

Abstract
Separate from scholarship in religion and medicine, a burgeoning field in religion and population health, includes religion and reproductive health. In a survey of existing literature, we analyzed data by religious affiliation, discipline, geography and date. We found 377 peer-reviewed articles; most were categorized as family planning (129), sexual behavior (81), domestic violence (39), pregnancy (46), HIV/AIDS (71), and STDs (61). Most research occurred in North America (188 articles), Africa (52), and Europe (47). Article frequency increased over time, from 3 articles in 1980 to 38 articles in 2008. While field growth is evident, there is still no cohesive "scholarship" in religion and reproductive health.

Abstract
OBJECTIVE To examine factors that influence the morbidity and mortality of peripartum hysterectomy and analyze the effect of hospital volume on maternal mortality. METHODS We examined women who underwent peripartum hysterectomy at the time of cesarean delivery in a quality and resource utilization database. Procedure-associated intraoperative, perioperative, and postoperative medical complications, length of stay, intensive care unit use, and maternal mortality were analyzed. Hospitals were stratified into tertiles based on procedure volume and complications and compared using adjusted generalized estimating equations. Results are reported as odds ratios. RESULTS Maternal mortality among the 2,209 women who underwent peripartum hysterectomy was 1.2%. After adjusting for other clinical and demographic factors, perioperative mortality was 71% (odds ratio 0.29, 95% confidence interval 0.10-0.88) lower in women who underwent operation at high-volume hospitals compared with those treated at low-volume facilities. Hospital volume had no effect on the rates of intraoperative injuries, medical complications, length of stay, or transfusion. In contrast, compared with women treated at low-volume centers, patients who underwent operation at high-volume hospitals had a lower incidence of perioperative surgical complications (odds ratio 0.66, 95% confidence interval 0.47-0.93) and a lower rate of intensive care unit usage (odds ratio 0.53, 95% confidence interval 0.34-0.83). CONCLUSION Peripartum hysterectomy is associated with substantial morbidity and mortality. Maternal mortality is lower when the procedure is performed in high-volume hospital settings.

Abstract
OBJECTIVE To determine the effect of maternal body mass index (BMI) and pregnancy weight gain on neonatal illness severity in very low birth weight infants. METHODS Cohort study of infants with birth weight less than 1500 g at a level 3 Neonatal Intensive Care Unit from July 2003 to July 2005, n = 301. The main outcome included neonatal illness severity, as measured by the Score for Neonatal Acute Physiology (SNAP). SNAP was investigated in relationship to maternal BMI and pregnancy weight gain. Statistical analysis included Pearson correlation, ANOVA and multivariable linear regression. RESULTS At delivery and pre-pregnancy, 49 and 54% of mothers were overweight, respectively. Black mothers were more likely to be overweight with less pregnancy weight gain compared with white mothers. After controlling for confounding variables, maternal pre-pregnancy BMI, pregnancy BMI and weight gain were not associated with neonatal illness. CONCLUSIONS In our population of very low birth weight infants, maternal BMI was not associated with neonatal illness severity. Black mothers had higher pre-pregnancy BMI and less weight gain than white mothers. The significance of these differences needs further exploration.
