Recognizing racial and ethnic disparities in women's reproductive health is not enough.

This Views and Reviews is a compilation of reports summarizing the published literature describing racial and ethnic disparities in polycystic ovary syndrome, fibroids, endometriosis, assisted reproductive technology, and disorders of mental health in women. The disparities are unique for each of these conditions and encompass disease prevalence and severity, access to care, and the outcomes of treatment.

Necesidades en salud sexual y reproductiva en migrantes de origen venezolano en el municipio de Cali (Colombia) / Sexual and reproductive health needs of Venezuelan migrants in the municipality of Cali, Colombia / Necessidades de saúde sexual e reprodutiva de migrantes de origem venezuelana no município de Cali (Colômbia)

RESUMEN Objetivo. Este estudio busca comprender las necesidades asociadas con la salud sexual y reproductiva (SSR) de migrantes de origen venezolano asentados de forma temporal o permanente en Santiago de Cali, Colombia. Método. Se realizó un estudio cualitativo con migrantes de origen venezolano de entre 15 y 60 años. Los participantes se seleccionaron mediante la técnica de bola de nieve, y la recopilación de la información se inició con personas referenciadas por las organizaciones de personas migrantes y luego con recorridos en zonas de alta concentración de personas migrantes de origen venezolano. Se realizaron entrevistas en profundidad y análisis de contenido temático. Resultados. Participaron 48 personas migrantes, de las cuales 70,8% no tenía regularizada su condición migratoria y se hallaban en condiciones de vulnerabilidad socioeconómica. Las personas participantes contaban con pocos recursos económicos, tenían falta de oportunidades de trabajo, precariedad de capital humano y niveles variables de capital social, sumado a una integración social débil que limitaba su apropiación como titulares de derechos. El estatus migratorio se constituye en una barrera para el acceso a los servicios de salud y otros servicios sociales. Sobresalen las necesidades de información sobre derechos de salud sexual y reproductiva, un mayor riesgo entre jóvenes de 15 y 29 años y en la comunidad LGBTIQ+, debido a la mayor vulnerabilidad y la exposición a espacios inseguros para su autocuidado, aseo personal e intimidad, necesidades de atención y tratamiento de infecciones de transmisión sexual, apoyo psicosocial por violencia, consumo de sustancias psicoactivas, conflictos familiares y procesos de transición de género. Conclusiones. Las necesidades en temas de salud sexual y reproductiva de las personas migrantes de origen venezolano están determinadas por sus condiciones de vida y trayectorias migratorias.

ABSTRACT Objective. This study seeks to understand the needs associated with the sexual and reproductive health of migrants of Venezuelan origin settled temporarily or permanently in Santiago de Cali, Colombia. Methods. A qualitative study was conducted with Venezuelan migrants between 15 and 60 years old. Participants were selected using the snowball technique. Information was initially gathered from people identified by migrant organizations, followed by information gathering in areas with high concentrations of migrants of Venezuelan origin. In-depth interviews were held, and thematic content was analyzed. Results. Of the 48 migrants who participated, 70.8% did not have legal migratory status and were living in conditions of socioeconomic vulnerability. The participants had scarce economic resources, a lack of job opportunities, precarious human capital, and varying levels of social capital, coupled with weak social integration that limited their awareness and appropriation of their rights. Immigration status constituted an access barrier to health services and other social services. There was a particular need for information on sexual and reproductive health rights, with increased risk among young people 15 to 29 years old and members of the LGBTIQ+ community, due to their greater vulnerability and exposure to unsafe spaces for self-care, personal hygiene, and privacy, in addition to their greater need for health care, treatment of sexually transmitted infections, psychosocial support for violence, substance abuse, family conflicts, and gender transition processes. Conclusions. The sexual and reproductive health needs of Venezuelan migrants are determined by their living conditions and migratory experiences.

RESUMO Objetivo. Compreender as necessidades associadas à saúde sexual e reprodutiva (SSR) dos migrantes de origem venezuelana estabelecidos temporária ou permanentemente em Santiago de Cali, Colômbia. Método. Foi realizado um estudo qualitativo com migrantes de origem venezuelana entre 15 e 60 anos. Os participantes foram selecionados pela técnica de bola de neve. A coleta de informações começou com pessoas encaminhadas por organizações de migrantes e, posteriormente, percorrendo áreas com alta concentração de migrantes de origem venezuelana. Foram realizadas entrevistas em profundidade e análise de conteúdo temático. Resultados. Participaram 48 migrantes, dos quais 70,8% não tinham sua situação imigratória regularizada e se encontravam em situação de vulnerabilidade socioeconômica. Os participantes tinham poucos recursos econômicos, falta de oportunidades de trabalho, capital humano precário e níveis variáveis de capital social, somados a uma fraca integração social que limitava a efetivação dos direitos dos quais são titulares. O status migratório é uma barreira ao acesso aos serviços de saúde e outros serviços sociais. Destacam-se as necessidades de informação sobre direitos à saúde sexual e reprodutiva, maior risco entre jovens de 15 a 29 anos e na comunidade LGBTIQ+ - devido à maior vulnerabilidade e exposição a espaços inseguros para autocuidado, higiene pessoal e privacidade -, necessidade de cuidados e tratamento de infecções sexualmente transmissíveis, apoio psicossocial em casos de violência, consumo de substâncias psicoativas, conflitos familiares e processos de transição de gênero. Conclusões. As necessidades em matéria de saúde sexual e reprodutiva dos migrantes de origem venezuelana são determinadas por suas condições de vida e trajetórias migratórias.

Reproductive Health Disparities in the USA: Self-Reported Race/Ethnicity Predicts Age of Menarche and Live Birth Ratios, but Not Infertility.

Self-identified race/ethnicity and socioeconomic status (SES) contribute to disparities in several health domains, although research on their effects on women's reproductive function has largely focused on links between SES and age of menarche. Here, we assessed whether race/ethnicity, SES, and downstream correlates of SES such as food security and health-insurance security are associated with age of menarche, infertility, and live birth ratios (ratios of recognized pregnancies resulting in live births) in the USA. We used cross-sectional data from 1694 women aged 12-18 years for menarche (2007-2016), 974 women aged 23-45 for infertility (2013-2016), and 1714 women aged 23-45 for live birth ratios (2007-2016) from the National Health and Nutrition Examination Survey. We estimated multiple linear and logistic regressions with survey weights to test these associations. When controlling for lifestyle (activity levels, smoking, alcohol consumption) and physiological factors (diabetes, weight status), non-Hispanic (NH) black and Hispanic girls reported a significantly lower age of menarche by about 4.3 (standard error [SE] = 0.08, p < 0.001), and 3.2 months (SE = 0.09, p < 0.001), respectively, relative to NH white girls. NH black women reported live birth ratios 9% (SE = 0.02, p < 0.001) lower than NH white women. Women with unstable health insurance reported live birth ratios 6% (SE = 0.02, p = 0.02) lower than women with stable health insurance. Race/ethnicity, SES, and its downstream correlates were not associated with infertility. One hypothesized explanation for observed disparities in age of menarche and live birth ratios is the embodiment of discrimination faced by NH black women within the USA. Our findings also underscore the importance of health insurance access for favorable reproductive health outcomes. Future work should elucidate the role of embodied discrimination and other downstream correlates of SES in modulating women's reproductive health outcomes to inform strategies to mitigate health disparities.

Behind bars: the burden of being a woman in Brazilian prisons.

BACKGROUND: Brazil has the third largest prison population in the world. In 2016, the female prison population totaled 42,000, an increase of 656% over the population recorded in the early 2000s. The objective of this study was to describe the socialeconomic and reproductive health of women in Brazilian prisons, and the specific assistance received within the prison system. METHODS: This is a first of its kind national survey conducted in 15 female prisons in eight Brazilian states between 2014 and 2015. The sample consisted of 1327 women in closed or semi-open prison regimes. Data collection used Audio Computer-Assisted Self-Interviewing (ACASI). STATA v.15. Was use in analysis. The study was submitted to the Research Ethics Committee of the Federal University of Ceará, under CEP protocol No. 1,024,053. RESULTS: The population was overwhelmingly Black or Brown, poor and little educated. When women worked previously, they had worked as domestic servants and were the sole source of income for their families. Most were mothers, with 39% having children less than 10 years old, now in the care of others. Most were in jail for drug-related crimes. Prisons were crowded, with more than 2/3rds of the inmates sharing a cell with 6 or more inmates. Services were provide, but women had not had a cervical cancer screening within the past 3 years and breast cancer screening was not conducted. CONCLUSIONS: Overall, given their backround and prison conditions they are unlikely to change the circumstances that brought them to prison in the first place.

Dietary and Physical Activity Behaviours in African Migrant Women Living in High Income Countries: A Systematic Review and Framework Synthesis.

Dietary and physical activity behaviours during preconception and in pregnancy are important determinants of maternal and child health. This review synthesised the available evidence on dietary and physical activity behaviours in pregnant women and women of childbearing age women who have migrated from African countries to live in high income countries. Searches were conducted on Medline, Embase, PsycInfo, Pubmed, CINAHL, Scopus, Proquest, Web of Science, and the Cochrane library. Searches were restricted to studies conducted in high income countries and published in English. Data extraction and quality assessment were carried out in duplicate. Findings were synthesised using a framework approach, which included both a priori and emergent themes. Fourteen studies were identified; ten quantitative and four qualitative. Four studies included pregnant women. Data on nutrient intakes included macro- and micro-nutrients; and were suggestive of inadequacies in iron, folate, and calcium; and excessive sodium intakes. Dietary patterns were bicultural, including both Westernised and African dietary practices. Findings on physical activity behaviours were conflicting. Dietary and physical activity behaviours were influenced by post-migration environments, culture, religion, and food or physical activity-related beliefs and perceptions. Further studies are required to understand the influence of sociodemographic and other migration-related factors on behaviour changes after migration.

Disparities in Preconception Health Indicators - Behavioral Risk Factor Surveillance System, 2013-2015, and Pregnancy Risk Assessment Monitoring System, 2013-2014.

PROBLEM/CONDITION: Preconception health is a broad term that encompasses the overall health of nonpregnant women during their reproductive years (defined here as aged 18-44 years). Improvement of both birth outcomes and the woman's health occurs when preconception health is optimized. Improving preconception health before and between pregnancies is critical for reducing maternal and infant mortality and pregnancy-related complications. The National Preconception Health and Health Care Initiative's Surveillance and Research work group suggests ten prioritized indicators that states can use to monitor programs or activities for improving the preconception health status of women of reproductive age. This report includes overall and stratified estimates for nine of these preconception health indicators. REPORTING PERIOD: 2013-2015. DESCRIPTION OF SYSTEMS: Survey data from two surveillance systems are included in this report. The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing state-based, landline and cellular telephone survey of noninstitutionalized adults in the United States aged ≥18 years that is conducted by state and territorial health departments. BRFSS is the main source of self-reported data for states on health risk behaviors, chronic health conditions, and preventive health services primarily related to chronic disease in the United States. The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing U.S. state- and population-based surveillance system administered collaboratively by CDC and state health departments. PRAMS is designed to monitor selected maternal behaviors, conditions, and experiences that occur before, during, and shortly after pregnancy that are self-reported by women who recently delivered a live-born infant. This report summarizes BRFSS and PRAMS data on nine of 10 prioritized preconception health indicators (i.e., depression, diabetes, hypertension, current cigarette smoking, normal weight, recommended physical activity, recent unwanted pregnancy, prepregnancy multivitamin use, and postpartum use of a most or moderately effective contraceptive method) for which the most recent data are available. BRFSS data from all 50 states and the District of Columbia were used for six preconception health indicators: depression, diabetes (excluded if occurring only during pregnancy or if limited to borderline/prediabetes conditions), hypertension (excluded if occurring only during pregnancy or if limited to borderline/prehypertension conditions), current cigarette smoking, normal weight, and recommended physical activity. PRAMS data from 30 states, the District of Columbia, and New York City were used for three preconception health indicators: recent unwanted pregnancy, prepregnancy multivitamin use, and postpartum use of a most or moderately effective contraceptive method by women or their husbands or partners (i.e., male or female sterilization, hormonal implant, intrauterine device, injectable contraceptive, oral contraceptive, hormonal patch, or vaginal ring). Heavy alcohol use during the 3 months before pregnancy also was included in the prioritized set of 10 indicators, but PRAMS data for each reporting area are not available until 2016 for that indicator. Therefore, estimates for heavy alcohol use are not included in this report. All BRFSS preconception health estimates are based on 2014-2015 data except two (hypertension and recommended physical activity are based on 2013 and 2015 data). All PRAMS preconception health estimates rely on 2013-2014 data. Prevalence estimates of indicators are reported for women aged 18-44 years overall, by age group, race-ethnicity, health insurance status, and reporting area. Chi-square tests were conducted to assess differences in indicators by age group, race/ethnicity, and insurance status. RESULTS: During 2013-2015, prevalence estimates of indicators representing risk factors were generally highest and prevalence estimates of health-promoting indicators were generally lowest among older women (35-44 years), non-Hispanic black women, uninsured women, and those residing in southern states. For example, prevalence of ever having been told by a health care provider that they had a depressive disorder was highest among women aged 35-44 years (23.1%) and lowest among women aged 18-24 years (19.2%). Prevalence of postpartum use of a most or moderately effective method of contraception was lowest among women aged 35-44 years (50.6%) and highest among younger women aged 18-24 years (64.9%). Self-reported prepregnancy multivitamin use and getting recommended levels of physical activity were lowest among non-Hispanic black women (21.6% and 42.8%, respectively) and highest among non-Hispanic white women (37.8% and 53.8%, respectively). Recent unwanted pregnancy was lowest among non-Hispanic white women and highest among non-Hispanic black women (5.0% and 11.6%, respectively). All but three indicators (diabetes, hypertension, and use of a most or moderately effective contraceptive method) varied by insurance status; for instance, prevalence of current cigarette smoking was higher among uninsured women (21.0%) compared with insured women (16.1%), and prevalence of normal weight was lower among women who were uninsured (38.6%), compared with women who were insured (46.1%). By reporting area, the range of women reporting ever having been told by a health care provider that they had diabetes was 5.0% (Alabama) to 1.9% (Utah), and women reporting ever having been told by a health care provider that they had hypertension ranged from 19.2% (Mississippi) to 7.0% (Minnesota). INTERPRETATION: Preconception health risk factors and health-promoting indicators varied by age group, race/ethnicity, insurance status, and reporting area. These disparities highlight subpopulations that might benefit most from interventions that improve preconception health. PUBLIC HEALTH ACTION: Eliminating disparities in preconception health can potentially reduce disparities in two of the leading causes of death in early and middle adulthood (i.e., heart disease and diabetes). Public health officials can use this information to provide a baseline against which to evaluate state efforts to improve preconception health.

'It means everyone should know their status': exploring lay conceptions of sickle cell trait and sickle cell trait screening among African Americans within middle reproductive age.

OBJECTIVE: This study examined the meaning of sickle cell trait and sickle cell trait screening from the lay perspective of African Americans. DESIGN AND METHODS: African Americans (N = 300), ages 18-35 and unaware of their sickle cell trait status, completed two open-ended questions from a larger survey. One question asked for their understanding of sickle cell trait; the other asked for their understanding of sickle cell trait screening. Content analysis occurred in two phases: (1) In vivo and holistic coding; and (2) focused coding. RESULTS: Four categories emerged illustrating lay conceptions of sickle cell trait; (1) Perceived as an illness; (2) Perceived recognition of the inheritance pattern of sickle cell trait; (3) Perceived lack of knowledge of sickle cell trait; and (4) Perceived importance of sickle cell trait. Five categories emerged illustrating lay conceptions for sickle cell trait screening: (1) Perceived recognition that screening means getting tested for sickle cell trait; (2) Perceived lack of knowledge of sickle cell trait screening; (3) Perceived health benefit of sickle cell trait screening; (4) Perceived importance of sickle cell trait screening; and (5) Perceived barriers to sickle cell trait screening. CONCLUSIONS: Sickle cell trait and sickle cell trait screening are concepts that are both regarded as important among this high-risk population. However, there is still misunderstanding concerning the hereditary nature and reproductive implications of sickle cell trait. Interventions seeking to improve communication on the need for sickle cell trait screening should begin by identifying what the population at large understands, knows and/or believes to improve their ability to make informed health decisions.

Adverse effects of female obesity and interaction with race on reproductive potential.

Across the reproductive spectrum, obesity is associated with greater risks for adverse health outcomes, including higher rates of infertility, subfertility, early pregnancy loss, fetal deaths and stillbirths, congenital anomalies, and pregnancy complications. The excess reproductive morbidity associated with obesity may increase with longer duration, making the current trends among children and young adults particularly critical in terms of their future reproductive potential. Obese women have a lower chance of pregnancy following in vitro fertilization (IVF), require higher dosages of gonadotropins, and have reduced rates of implantation, clinical intrauterine gestation, and live birth rates and increased rates of pregnancy loss, as well as greater risks for prematurity and preeclampsia even when stratified by plurality. Racial and ethnic differences by overweight and obesity in IVF outcomes have been reported. Compared with normal-weight women, failure to achieve a clinical intrauterine gestation is significantly more likely among obese women overall, normal-weight and obese Asian women, normal-weight Hispanic women, and overweight and obese Black women. Among women who do conceive, compared with normal-weight women, failure to achieve a live birth is significantly more likely among overweight and obese women overall, and among overweight and obese Asian women, overweight and obese Hispanic women, and normal-weight and obese Black women. Although weight loss should theoretically be the first line of therapy for obese women, other lifestyle factors, such as regular physical exercise, elimination of tobacco use and alcohol consumption, and stress management, may be of more immediate benefit in achieving conception.

Healthcare-seeking behaviour in relation to sexual and reproductive health among Thai-born women in Sweden: a qualitative study.

Thailand is one of the most common countries of origin among immigrants in Sweden and Thai immigrants comprise the immigrant group most frequently diagnosed with HIV. Little is known about their healthcare-seeking behaviour and views on HIV prevention. This study explored Thai women's healthcare-seeking behaviour in relation to sexual and reproductive health and their views on HIV prevention. Nineteen in-depth interviews were conducted with Thai-born women in the Stockholm area. Three themes were identified: (1) poor access to healthcare in Sweden, preferring to seek care in Thailand; (2) partners playing a key role in women's access to healthcare; (3) no perceived risk of HIV, but a positive attitude towards prevention. Despite expressing sexual and reproductive healthcare needs, most women had not sought this type of care, except for the cervical cancer screening programme to which they had been invited. Identified barriers for poor access to healthcare were lack of knowledge about the healthcare system and language difficulties. To achieve 'healthcare on equal terms', programmes and interventions must meet Thai women's healthcare needs and consider what factors influence their care-seeking behaviour. Integrating HIV prevention and contraceptive counselling into the cervical screening programme might be one way to improve access.

FASN, dietary fat intake, and risk of uterine leiomyomata in the Black Women's Health Study.

OBJECTIVE: To replicate results from a previous genome-wide association study of European ancestry women, in which a positive association was found between uterine leiomyomata (UL) and rs4247357, a single-nucleotide polymorphism located near the fatty acid synthase (FASN) gene. DESIGN: Prospective cohort study. SETTING: Not applicable. PATIENT(S): African-American women aged 23-50 years, who were premenopausal and had an intact uterus in 1997. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): We genotyped rs4247357 among 2,301 incident UL cases and 3,005 controls from the Black Women's Health Study (1997-2011). Odds ratios (ORs) and 95% confidence intervals (CI) were estimated using logistic regression with control for age, geographic region of residence, and percent European ancestry using a panel of validated ancestry informative markers. RESULT(S): Overall, rs4247357 was not associated with UL risk. Relative to the CC genotype, ORs were 1.04 (95% CI 0.92-1.19) for the AC genotype and 1.09 (95% CI 0.93-1.29) for the AA genotype. A positive association was found, however, among those with higher European ancestry (≥40%). Relative to the CC genotype, ORs were 2.03 (95% CI 1.12-3.69) for the AC genotype and 2.44 (95% CI 1.20-4.96) for the AA genotype. Dietary fat intake also appeared to modify the FASN-UL association. CONCLUSION(S): Although there was little overall association between rs4247357 and UL risk, a positive association was observed among women with ≥40% European ancestry. Direct sequencing of this genomic region might be warranted to determine whether rs4247357, or some other variant, is causally related to UL.

Medical borderlands: engineering the body with plastic surgery and hormonal therapies in Brazil.

This paper explores medical borderlands where health and enhancement practices are entangled. It draws on fieldwork carried out in the context of two distinct research projects in Brazil on plastic surgery and sex hormone therapies. These two therapies have significant clinical overlap. Both are made available in private and public healthcare in ways that reveal the class dynamics underlying Brazilian medicine. They also have an important experimental dimension rooted in Brazil's regulatory context and societal expectations placed on medicine as a means for managing women's reproductive and sexual health. Off-label and experimental medical use of these treatments is linked to experimental social use: how women adopt them to respond to the pressures, anxieties and aspirations of work and intimate life. The paper argues that these experimental techniques are becoming morally authorized as routine management of women's health, integrated into mainstream Ob-Gyn healthcare, and subtly blurred with practices of cuidar-se (self-care) seen in Brazil as essential for modern femininity.

Racial and ethnic disparities in internet use for seeking health information among young women.

To examine the influence of race/ethnicity on seeking health information from the Internet among women aged 16-24 years, the authors conducted a self-administered survey on 3,181 women regarding their Internet use and obtaining information on reproductive health (menstruation, contraception, pregnancy, sexually transmitted infections) and general health from the Internet. The authors performed multivariate logistic regression to examine the association between race/ethnicity and online health-related information seeking after adjusting for covariates. Racial/ethnic disparities were noted in overall Internet use and its use to locate health information. Overall, more White (92.7%) and Black (92.9%) women used the Internet than did Hispanics (67.5%). More White women (79.2%) used it to find health information than did Blacks and Hispanics (70.3% and 74.3%, respectively). Compared with White women, Blacks and Hispanics were less likely to seek information on contraception [(OR 0.73, 95% CI 0.58-0.91) and (OR 0.75, 95% CI 0.61-0.92)] and more likely to seek information on pregnancy tests [(OR 1.67, 95% CI 1.28-2.18) and (OR 1.40, 95% CI 1.09-1.81] and sexually transmitted infections [(OR 1.39, 95% CI 1.11-1.73) and (OR 1.25, 95% CI 1.01-1.54)], respectively. With regard to general health issues-such as how to quit smoking, how to lose weight, alcohol/drug use, mood disorders, and skin disorders-Blacks, but not Hispanics, were significantly less likely to seek online information than were Whites. Disparities in the way that women from different backgrounds use the Internet for health-related information could be associated with overall health awareness.

Reproductive cancer risk factors among Alaska Native women: the Alaska Education and Research Towards Health (EARTH) Study.

BACKGROUND: The purpose of this study was to provide estimates for the prevalence of reproductive cancer risk factors among Alaska Native (AN) women who enrolled in the Alaska Education and Research Towards Health (EARTH) Study from 2004 to 2006. METHODS: A total of 2,315 AN women 18 years or older completed reproductive health questions as part of a comprehensive health history questionnaire. The reproductive health section included menstrual status (age at menarche and menopause), pregnancy and live birth history, use of hormonal contraception, hormone replacement therapy, and history of hysterectomy and/or oophorectomy. RESULTS: A total of 463 (20%) of women experienced menarche before age 12 with a decline in mean age at menarche by age cohort. More than 86% had been pregnant (mean number of pregnancies, 3.8; mean number of live births, 2.9). More than one half of women (58%) had their first live birth between the ages of 18 and 24. Almost 28% of participants had completed menopause, of whom 24% completed menopause after age 52. Fewer than half (43%) reported ever using hormone replacement therapy. Almost two thirds (62%) reported ever using oral contraceptives, and fewer reported ever using birth control shots (30%) or implants (10%). CONCLUSIONS: This study is unique in reporting reproductive health factors among a large group of AN women. These data show that AN women have selective protective factors for reproductive cancers, including low nulliparity rates, low use of menopausal estrogens, and common use of contraceptive hormones. However, analysis by age cohorts indicates decreasing age at menarche that might increase the risk for reproductive cancers among AN women in the future.

Revisiting the immigrant paradox in reproductive health: the roles of duration of residence and ethnicity.

The immigrant paradox refers to the contrasting observations that immigrants usually experience similar or better health outcomes than the native-born population despite socioeconomic disadvantage and barriers to health care use. This paradox, however, has not been examined simultaneously in relation to varying degrees of exposure to the receiving society and across multiple outcomes and risk factors. To advance knowledge on these issues, we analysed data of the Maternity Experiences Survey, a nationally representative cross-sectional survey of 6421 Canadian women who delivered singleton infants in 2006-07. We compared the prevalence of adverse pregnancy outcomes and related risk factors according to women's ethnicity and time since migration to Canada. We calculated prevalences and prevalence ratios (PR) with 95% confidence intervals. Compared to Canadian-born women of European descent, recent immigrants were at lower risk of preterm delivery and morbidity during pregnancy despite having the highest prevalence of low income and low support during pregnancy among all groups, but the paradox was not observed among immigrants with a longer stay in Canada. In contrast, recent immigrants were at higher risk of postpartum depression. Immigrants of non-European origin also had higher prevalence of postpartum depression, irrespective of their length of residence in Canada, but immigrants from European-origin countries did not. Exposure to Canada was also positively associated with higher alcohol and tobacco consumption and body mass index. Canadian-born women of non-European descent were at higher risk of preterm birth and hospitalisation during pregnancy than their European-origin counterparts. Our findings suggest that the healthy migrant hypothesis and the immigrant paradox have limited generalisability. These hypotheses may be better conceptualised as outcome-specific and dependent on immigrants' ethnicity and length of stay in the receiving country.

Genetic variants and environmental factors associated with hormonal markers of ovarian reserve in Caucasian and African American women.

BACKGROUND: The ovarian reserve (number and quality of oocytes) is correlated with reproductive potential as well as somatic health, and is likely to have multiple genetic and environmental determinants. Several reproductive hormones are closely linked with the oocyte pool and thus can serve as surrogate markers of ovarian reserve. However, we know little about the underlying genes or genetic variants. METHODS: We analyzed genetic variants across the genome associated with two hormonal markers of ovarian reserve, FSH and anti-Mullerian hormone, in a reproductively normal population of Caucasian (n = 232) and African American (n = 200) women, aged 25-45 years. We also examined the effects of environmental or lifestyle factors on ovarian reserve phenotypes. RESULTS: We identified one variant approaching genome-wide significance (rs6543833; P= 8.07 × 10⁻8) and several nominal variants nearby and within the myeloid-associated differentiation marker-like (MYADML) gene, that were associated with FSH levels in African American women; these were validated in Caucasian women. We also discovered effects of smoking and oral contraceptive use on ovarian reserve phenotypes, with alterations in several reproductive hormones. CONCLUSIONS: This work is the largest study on ovarian reserve in women of reproductive age and is the only genome-wide study on ovarian reserve markers. The genes containing or near the identified variants have no known roles in ovarian biology and represent interesting candidate genes for future investigations. The discovery of genetic markers may lead to better long-range predictions of declining ovarian function, with implications for reproductive and somatic health.

Chronic disease risk factors among American Indian/Alaska Native women of reproductive age.

INTRODUCTION: The magnitude of chronic conditions and risk factors among American Indian/Alaska Native women of reproductive age is unknown. The objective of our study was to estimate this magnitude. METHODS: We analyzed data for 2,821 American Indian/Alaska Native women and 105,664 non-Hispanic white women aged 18 to 44 years from the 2005 and 2007 Behavioral Risk Factor Surveillance System. We examined prevalence of high cholesterol, high blood pressure, diabetes, body mass index (kg/m(2)) ≥25.0, physical inactivity, smoking, excessive alcohol consumption, and frequent mental distress, and the cumulative number of these chronic conditions and risk factors (≥3, 2, 1, or 0). In a multivariable, multinomial logistic regression model, we examined whether American Indian/Alaska Native race was associated with the cumulative number of chronic conditions and risk factors. RESULTS: American Indian/Alaska Native women, compared with white women, had significantly higher rates of high blood pressure, diabetes, obesity, smoking, and frequent mental distress. Of American Indian/Alaska Native women, 41% had 3 or more chronic conditions or risk factors compared with 27% of white women (χ(2), P < .001). After adjustment for income, education, and other demographic variables, American Indian/Alaska Native race was not associated with having either 1, 2, or 3 or more chronic conditions or risk factors. CONCLUSION: Three out of every 5 American Indian/Alaska Native women aged 18 to 44 years have 3 or more chronic conditions or risk factors. Improving economic status and education for AI/AN women could help eliminate disparities in health status.
