RESUMEN

OBJECTIVE: We studied cis-women with uterine cancer presenting to the two Public Hospitals in Queens, New York from 2006 to 2015 to examine the relationship between nativity (birthplace) and survival. METHODS: A retrospective review of tumor registries identified women diagnosed with uterine cancer between January 1, 2006, and December 31, 2015. Data from 259 women were available for this analysis. RESULTS: Most women were born outside the United States (US) (76% versus 24%). The majority of US-born women were black (68%). Seventy-seven women (30%) were born in Latin America, 76 in the Caribbean Islands (29%) and 44 in Asia/South Asia (17%). Most women presented with stage I/II disease (70%) and endometrioid/mucinous histology (68%) with no significant differences observed among nativity groups. Kaplan-Meier estimated survival curves stratified by birthplace demonstrated significant differences in survival distributions among the groups using the log-rank test (P < 0.0001). The most favorable survival curves were observed among all foreign-born women, whereas the least favorable survival was demonstrated in US-born women. Time to death was analyzed using the Cox proportional hazards model. Adjusting for age of diagnosis, insurance status, stage, and treatment modality, Latin American and Asia/South Asia birthplace was significantly associated with increased survival time. CONCLUSION: An immigrant health paradox was defined for foreign-born Latin American and Asian/South Asian women presenting to the two Public Hospitals of Queens, New York, as women born in these geographic regions were less likely to die at any given time compared to those born in the United States.

RESUMEN

BACKGROUND: Decision-making around birthplace is complex and multifactorial. The role of clinicians is to provide unbiased, evidence-based information to support women and birthing people to make decisions based on what matters to them. Some decisions may fall outside of clinical guidance and recommendations. Birth Choices Clinics can provide an opportunity for extended discussion and personalized birthplace planning. This study aimed to explore the rationale behind choosing birthplace "outside of guidance" and examine the outcomes for women who attended a Birth Choices Clinic. METHODS: The study was descriptive using data extracted from clinical documentation and consultation. The data included demographic information, maternal characteristics, reason for choosing a midwifery-led birth setting, birthplace preference, and outcome. RESULTS: Eighty-two women used the Birth Choices Clinic between April 2022 and February 2023 in one large maternity unit in the UK. Reasons for choosing birth in a midwifery-led setting included having access to a birthing pool, to reduce the chance of obstetric interventions and pragmatic reasons. Sixty-five percent of women experienced a spontaneous vaginal birth, 10% experienced an assisted vaginal birth, and 23% experienced a cesarean birth. Of the 33 women who ultimately commenced labor care in a midwifery-led setting, 76% (n = 25/33) birthed in this setting without complications. Transfer rates in labor were similar to those in a "low-risk" pregnant population. DISCUSSION: Birth choice clinics may facilitate an understanding of material risk and support individualizing birth planning. There is evidence that women changed their planned birthplace, possibly in recognition of a move along the risk spectrum.

RESUMEN

AIM: The study explores the experiences of women with low-risk pregnancies and no complications who planned a home birth. DESIGN: A cross-sectional study was conducted using an online questionnaire. METHODS: The questionnaire included socio-demographic, obstetric and perinatal variables. Birth satisfaction was evaluated via the Spanish version of the childbirth experience questionnaire. The study group comprised home-birthing women in Catalonia, Spain. Data were collected from 1 January 2019 to 31 December 2021. Statistical analysis was performed using SPSS. RESULTS: A total of 236 women responded. They reported generally positive experiences, with professional support and involvement being the most highly rated dimensions. Better childbirth experiences were associated with labour lasting less than 12 h, no perineal injuries, no intrapartum transfers to hospital, euthocic delivery and the presence of a midwife. CONCLUSIONS: Women's positive home birth experiences were linked to active participation and midwife support. Multiparous women felt safer. Medical interventions, especially transfers to hospitals, reduced satisfaction, highlighting the need for improved care during home births. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Home births should be included among the birthplace options offered by public health services, given the extremely positive feedback reported by women who gave birth at home. IMPACT: Home birth is not an option offered under Catalonia's public health system only as a private service. The experience of home-birthing women is unknown. This study shows a very positive birth experience due to greater participation and midwife support. The results help stakeholders assess home birth's public health inclusion and understand valued factors, supporting home-birthing women. REPORTING METHOD: The study followed the STROBE checklist guidelines for cross-sectional studies. PUBLIC CONTRIBUTION: Women who planned a home birth participated in the pilot test to validate the instrument, and their contributions were collected by the lead researcher. The questionnaire gathered the participants' email addresses, and a commitment was made to disseminate the study's results through this means.

RESUMEN

Immigrants to Canada increasingly come from regions where child marriage (<18 years) is prevalent. We described the prevalence, demographic characteristics, and reproductive health correlates of marriage among births to Canadian-born and foreign-born adolescent mothers. Using Canadian birth registrations from 1990 to 2018, marriage prevalence, parental birth region, and parental age gap were examined by maternal birthplace (Canada and 12 world regions) among births to mothers <18 years. Adjusted odds ratios (AORs) of preterm birth (PTB), small for gestational age (SGA), and repeat birth were estimated for the joint associations of adolescent maternal age group (<18-year, 18-19-year, and 20-24-year), marriage, and nativity status (n = 1,904,200). Depending on maternal birthplace, marital births represented 2.6% to 81.8% of births to mothers <18 years. Marriage among mothers giving birth at <18 years was associated with higher proportions of parents from the same birthplace and larger parental age gaps. AORs of PTB tended to increase with lower maternal age. AORs of SGA were generally higher among births to foreign-born mothers. Marriage was associated with lower AORs of PTB and SGA among births to Canadian-born mothers and PTB among births to foreign-born mothers in the older adolescent age groups, but no association existed in the <18-year group. Marriage was positively associated with repeat birth in all adolescent age groups, with stronger associations in the <18-year group. The reproductive health correlates of marriage are similar between births to Canadian-born and foreign-born mothers <18 years but some differ between births to mothers <18 years and those to older adolescent mothers.

RESUMEN

OBJECTIVE: To estimate the association between maternal origin and obstetric anal sphincter injury (OASI), and assess if associations differed by length of residence. DESIGN: Population-based cohort study. SETTING: The Medical Birth Registry of Norway. POPULATION: Primiparous women with vaginal livebirth of a singleton cephalic fetus between 2008 and 2017 (n = 188 658). METHODS: Multivariable logistic regression models estimated adjusted odds ratios (aORs) for OASI with 95% CI by maternal region of origin and birthplace. We stratified models on length of residence and paternal birthplace. MAIN OUTCOME MEASURES: OASI. RESULTS: Overall, 6373 cases of OASI were identified (3.4% of total cohort). Women from South Asia were most likely to experience OASI (6.2%; aOR 2.24, 95% CI 1.87-2.69), followed by those from Southeast Asia, East Asia & the Pacific (5.7%; 1.59, 1.37-1.83) and Sub-Saharan Africa (5.2%; 1.85, 1.55-2.20), compared with women originating from Norway. Among women born in the same region, those with short length of residence in Norway (0-4 years), showed the highest odds of OASI. Migrant women across most regions of origin had the lowest risk of OASI if they had a Norwegian partner. CONCLUSIONS: Primiparous women from Asian regions and Sub-Saharan Africa had up to two-fold risk of OASI, compared with women originating from Norway. Migrants with short residence and those with a foreign-born partner had higher risk of OASI, implying that some of the risk differential is due to sociocultural factors. Some migrants, especially new arrivals, may benefit from special attention during labour to reduce morbidity and achieve equitable outcomes. TWEETABLE ABSTRACT: Anal sphincter injury during birth is more common among Asian and Sub-Saharan migrants and particularly among recent arrivals.

RESUMEN

BACKGROUND: Cities such as Shenzhen in southern China have large immigrant populations, and the reproductive health issues of pregnant women in these populations have not received sufficient attention. Stillbirth seriously threatens their health and is becoming a social issue worthy of attention. We conducted this study to estimate the trend in stillbirths at 28 or more gestational weeks and the related sociodemographic characteristics of pregnant women among a large internal migrant population in South China. METHODS: A stillbirth is defined as a baby born with no signs of life after a given threshold, and are restricted to births of 28 weeks of gestation or longer, with a birth weight of at least 1000 g for international comparison. A population-based retrospective cohort of all births from January 2010 to December 2019 in Baoan, Shenzhen, was conducted using the Shenzhen Birth Registry Database. The overall stillbirth rate and year-specific stillbirth rate were calculated as the number of foetal deaths ≥28 gestational weeks or a birth weight ≥ 1000 g divided by the number of births over the last decade or in each year, respectively. The associations between the risk of stillbirth and maternal sociodemographic status were assessed using logistic regression. Spearman's rank correlation was calculated to evaluate the correlation between the economic status of the maternal birthplace and the stillbirth. RESULTS: An overall stillbirth rate of 4.5 per 1000 births was estimated in a total of 492,184 births in our final analysis. Migrant women accounted for 87% of the total population but had a higher stillbirth rate (4.8 per 1000 births) than the permanent population (2.8 per 1000 births). The stillbirth rate varied by region of maternal birthplace, from 4.1 per 1000 births in women from East China to 5.7 per 1000 births in women from West China. The GDP per capita of the maternal birthplace was strongly correlated with the stillbirth rate. CONCLUSIONS: Large disparities in the stillbirth rate exist between migrant and permanent populations and among regions of maternal birthplace in China. Strategies targeting migrant women based on their maternal birthplace are needed to further reduce the burden of stillbirth.

RESUMEN

Earlier research shows that wide regional variations exist in the success of athletes' talent development but is divided with respect to the role of urbanity: both low and high urbanity have been identified as settings that contribute to the presence of talent hotspots. In this article, we intend to provide more insight into the role of urbanity in talent development in Dutch football. We used public data on the regional background of male elite players (N = 825) and combined this with public data on municipal characteristics from Statistics Netherlands and other sources: urbanity, football participation, instructional resources and population composition effects (migration background and income of inhabitants). Linear regression analysis showed that football participation, the proportion of non-western migrants and median income predict "talent yield", i.e., the proportion of young people that reach an elite level in a municipality. Urbanity does not have an independent influence when the proportion of non-western migrants in the municipality is taken into account. The presence of instructional resources does not have an independent influence. The results suggest that characteristics of the built environment, such as indoor and outdoor play opportunities, may be less influential in talent development than previously assumed.

RESUMEN

BACKGROUND: Updated prevalence and outcome data for nonobese NAFLD for the multi-ethnic US population is limited. OBJECTIVES: We aimed to investigate the prevalence, clinical characteristics and mortality of obese and nonobese individuals with NAFLD in the United Sates. METHODS: A retrospective study was conducted using the 1999-2016 NHANES databases. We determined hazard ratio stratified by obesity status in NAFLD individuals using Cox regression and log-rank test. RESULTS: Overall NAFLD prevalence was 32.3%: 22.7% were obese and 9.6% were nonobese, with increasing trend over time for obese NAFLD, but not nonobese NAFLD. Amongst those with NAFLD, 29.7% (95% CI: 27.8%-31.7%) were nonobese, of which 13.6% had lean NAFLD. Nonobese NAFLD was more common in older (40.9% if ≥ 65 vs. 24.2% if < 65 years), male (34.0% vs. 24.2%) and foreign-born Asian people (39.8% vs. 11.4%) and uncommon in black (11.5% vs 30-35% in other ethnicities, P < 0.001). Metabolic comorbidities were common in nonobese NAFLD individuals who also had more advanced fibrosis. Nonobese NAFLD individuals had higher 15-year cumulative all-cause mortality (51.7%) than obese NAFLD (27.2%) and non-NAFLD (20.7%) (P < 0.001). However, DM and fibrosis, but neither obese nor nonobese NAFLD compared to non-NAFLD was independently associated with higher mortality. CONCLUSION: Nonobese NAFLD makes up about one-third of the NAFLD in the United States (even higher in older, male and foreign-born individuals) and carries higher mortality than obese NAFLD. Screening for NAFLD should be considered in high-risk groups even in the absence of obesity.

RESUMEN

BACKGROUND: The purpose of this systematic review (PROSPERO Ref: CRD42017053264) was to describe and interpret the qualitative research on parent's decision-making and informed choice about their pregnancy and birth care. Given the growing evidence on the benefits of different models of maternity care and the prominence of informed choice in health policy, the review aimed to shed light on the research to date and what the findings indicate. METHODS: a systematic search and screening of qualitative research concerning parents' decision-making and informed choice experiences about pregnancy and birth care was conducted using PRISMA guidelines. A meta-synthesis approach was taken for the extraction and analysis of data and generation of the findings. Studies from 1990s onwards were included to reflect an era of policies promoting choice in maternity care in high-income countries. RESULTS: Thirty-seven original studies were included in the review. A multi-dimensional conceptual framework was developed, consisting of three analytical themes ('Uncertainty', 'Bodily autonomy and integrity' and 'Performing good motherhood') and three inter-linking actions ('Information gathering,' 'Aligning with a birth philosophy,' and 'Balancing aspects of a choice'). CONCLUSIONS: Despite the increasing research on decision-making, informed choice is not often a primary research aim, and its development in literature published since the 1990s was difficult to ascertain. The meta-synthesis suggests that decision-making is a dynamic and temporal process, in that it is made within a defined period and invokes both the past, whether this is personal, familial, social or historical, and the future. Our findings also highlighted the importance of embodiment in maternal health experiences, particularly when it comes to decision-making about care. Policymakers and practitioners alike should examine critically current choice frameworks to ascertain whether they truly allow for flexibility in decision-making. Health systems should embrace more fluid, personalised models of care to augment service users' decision-making agency.

RESUMEN

BACKGROUND: A previous study reported that Eastern-African-born black women in the United States had lower prevalence of estrogen receptor-negative breast cancer than those in US-born and Western-African-born black women, among whom the prevalence was similar. It is unknown whether the prevalence of triple-negative breast cancer (negative for estrogen receptor, progesterone receptor, and human epidermal growth factor 2 receptor) among black women in the United States differs similarly by birthplace. METHODS: In the National Program of Cancer Registries and US Cancer Statistics, the authors identified 65,211 non-Hispanic black women who were diagnosed with invasive breast cancer from 2010 through 2015 and were recorded as being born in the United States, East Africa, West Africa, or the Caribbean. The prevalence of triple-negative and hormone receptor-negative breast cancer (negative for estrogen receptor and progesterone receptor) among each group of foreign-born black women was compared with that among US-born black women and was expressed as the adjusted prevalence rate ratio, accounting for sociodemographic and tumor characteristics. Analyses were stratified by Census region, and region-specific estimates were summarized using random-effects meta-analyses. RESULTS: Compared with US-born black women, the prevalence rate ratio of triple-negative breast cancer was 0.92 (95% CI, 0.81-1.04) among Western-African-born, 0.87 (95% CI, 0.78-0.98) among Caribbean-born, and 0.53 (95% CI, 0.37-0.77) among Eastern-African-born black women. Patterns for hormone receptor-negative tumors were generally similar, although the differences between populations were attenuated. The test for heterogeneity by Census region was not significant in any of the comparisons (all P for heterogeneity >.05). CONCLUSIONS: The prevalence of triple-negative breast cancer among black women in the United States varied significantly by birthplace, particularly among Eastern-African-born black women. These findings underscore the importance of considering geographic origin in studies characterizing breast cancer among women of African descent in the United States and elsewhere.

RESUMEN

Although jihadist threats are regarded as foreign, most Islamist terror attacks in Europe and the United States have been orchestrated by Muslims born and raised in Western societies. In the present research, we explored a link between perceived deprivation of Western Muslims and endorsement of extremism. We suggest that Western-born Muslims are particularly vulnerable to the impact of perceived relative deprivation because comparisons with majority groups' peers are more salient for them than for individuals born elsewhere. Thus, we hypothesized that Western-born, compared with foreign-born, Muslims would score higher on four predictors of extremism (e.g., violent intentions), and group-based deprivation would explain these differences. Studies 1 to 6 ( Ns = 59, 232, 259, 243, 104, and 366, respectively) confirmed that Western-born Muslims scored higher on all examined predictors of extremism. Mediation and meta-analysis showed that group-based relative deprivation accounted for these differences. Study 7 ( N = 60) showed that these findings are not generalizable to non-Muslims.

RESUMEN

BACKGROUND: The aim of this study is to use data representative of the U.S. population to determine if households (HHs) age, birth country, and marital status, are strong predictors as HHs education for dental sealants, restorations, and caries in children 5 to 19 years of age. METHODS: A cross sectional analysis was performed with oral health data from three waves of the National Health and Nutrition Examination Survey (NHANES 2005 to 2010). The sample size consisted of children 5 to 19 years of age (n = 9151) and households > 18 years of age (n = 31,034). Dependent variables included the number of children with dental sealants, restorations, and caries. HHs independent variables consisted of gender, age, race, country of birth, HHs education level, marital status, and HHs spouse education. Multivariate regression analysis models were adjusted for HHs citizenship, health insurance, family size, and children age categories. RESULTS: The prevalence of children 5-19 years of age with dental sealants, restorations, and caries was 31.3, 43, and 15.8% respectively. The odds of children having sealants were higher among HHs with a college education or above OR 2.05 [1.54.-2.73] vs. HHs with a < 9th grade, in HHs ages 39-49 (OR 1.78 [1.41-2.24) vs. 18-29 years of age, and in HHs spouses with a college education and above OR 1.71 [1.14-2.56] vs. HHs with a < 9th grade. The odds of having at least one restored tooth were higher in children from HHs born in Mexico 1.74 [1.44-2.10] vs. US born. The highest odds for caries were among children from HHs that were never married 1.91 [1.47-2.48] vs. married HHs. In HHs with a college education the odds for caries in children were 0.31 (0.22-0.43) for college and above, and 0.78 (0.60-1.01) for some college. CONCLUSIONS: The odds of children having dental sealants were higher in HHs with a college education, however, HHs ages 30-49 provided higher odds for sealants than spouses with college education. HHs birth place increased the odds of children with restorations more than HHs education. Children from HHs that never married had higher odds of experiencing dental caries. Recognizing the impact of these HHs characteristics could augment efforts in the prevention of adverse oral health outcomes in U.S. children. Households' age, country of birth, and marital status, stronger predictor variables than education in the prevalence of dental sealants, restorations, and caries among US children 5-19 years of age, NHANES 2005-2010.

RESUMEN

OBJECTIVE: We studied cervical cancer patients who presented to the Public Hospital System in ethnically-diverse Queens, New York from 2000 to 2010 with the purpose of examining the relationship between nativity (birthplace) and survival. METHODS: A retrospective review of tumor registries was used to identify patients diagnosed with cervical cancer between January 1, 2000 and December 31, 2010. Using electronic medical records, data from 317 patients were available for this analysis. RESULTS: The majority of patients were born outside the United States (US) (85.5% versus 14.5%). One hundred patients (31.5%) were born in Latin America, 105 in the Caribbean Islands (33.1%), 48 in Asia (15.1%), 8 in the South Asia (2.5%), 10 in Russia/Eastern Europe (3.2%) and 46 (14.5%) in the United States. Patients presented at varying stages of disease: 51.4% at stage I, 19.6% at stage II, 19.6% at stage III, and 8.5% at stage IV. Kaplan-Meier estimated survival curves stratified by birthplace demonstrated significant differences in survival distributions among the groups using the log-rank test (P<0.0001). The most favorable survival curves were observed among patients born in Latin America and Asia whereas the least favorable was demonstrated in US-born patients. Time to death was analyzed using the Cox proportional hazards model. Adjusting for age at diagnosis, insurance status, stage and treatment modality, nodal metastases and hydronephrosis, birthplace was significantly associated with survival time (P<0.0001). CONCLUSION: An immigrant health paradox was defined for foreign-born Latino and Asian patients presenting with cervical cancer to the Public Hospital System of Queens, New York as patients born in Latin America and Asia were less likely to die at any given time compared to those born in the United States.

RESUMEN

Previous studies have found significant differences in the likelihood of becoming an elite athlete depending on community population sizes and densities, an effect known as the place of early development, or birthplace effect. However, the results have not been consistent between sports or European countries. As both professional and voluntary clubs are vital to the talent development systems in Europe, the proximity of an athlete's place of early development to the location of talent clubs may be an important predictor of the likelihood of becoming an elite athlete. Therefore, the primary purpose of this study was to investigate the place of early development effect and the effect of proximity to talent clubs. The samples included elite youth league athletes (579 football and 311 handball) and national youth athletes (85 football and 80 handball) and a comparison group of 147 221 football and 26 290 handball youth athletes. Odds ratios showed variations in the optimal community size and density across sports. Geospatial analyses of proximity to talent clubs highlighted a trend indicating that most national and elite youth league athletes in both sports had their place of early development in their sport near a talent club. The results suggest that proximity is an important predictor in the development of expertise across sports, but future studies need to clarify if proximity is important in other countries and sports.

RESUMEN

The surface of Hadean Earth was mainly covered with three types of rocks-komatiite, KREEP basalt and anorthosite-which were remarkably different from those on the modern Earth. The water-rock interaction between these rocks and water provided a highly reducing environment and formed secondary minerals on the surface of the rocks that are important for producing metallo-enzymes for the emergence of primordial life. Previous studies suggested a correlation between the active site of metallo-enzymes and sulfide minerals based on the affinity of their structures, but they did not discuss the origin of metallic elements contained in these minerals which is critical to understanding where life began. We investigated secondary minerals formed through water-rock interactions of komatiite in a subaerial geyser system, then discussed the relationship between the active site of metallo-enzymes and secondary minerals. Instead of komatiite, we used serpentinite collected from the Hakuba Happo area, Nagano Prefecture in central-north Japan, which is thought to be a modern analog for the Hadean environment. We found several minor minerals, such as magnetite, chromite, pyrite and pentlandite in addition to serpentine minerals. Pentlandite has not been mentioned in previous studies as one of the candidates that could supply important metallic elements to build metallo-enzymes. It has been shown to be a catalyst for hydrogen generation possibly, because of structural similarity to the active site of hydrogenases. We consider the possibility that nickel-iron sulfide, pentlandite, could be important minerals for the origin of life. In addition, we estimated what kinds of minor minerals would be obtained from the water-rock interaction of these rocks using thermodynamic calculations. KREEP basalt contains a large amount of iron and it could be useful for producing metallo-enzymes, especially ferredoxins-electron transfer enzymes, which may have assisted in the emergence of life.

RESUMEN

Contextual influences on talent development (e.g., birthplace effects) have become a topic of interest for sport scientists. Birthplace effects occur when being born in a certain city size leads to participation or performance advantages, typically for those born in smaller or mid-sized cities. The purpose of this study was to investigate birthplace effects in Portuguese volleyball players by analysing city size, as well as population density - an important but infrequently used variable. Participants included 4062 volleyball players (Mage = 33), 53.2% of whom were men. Using Portuguese national census data from 1981, we compared participants (within each sex) across five population categories. In addition, we used ANOVAs to study expertise and population density. Results indicated that men and women athletes born in districts of 200,000-399,999 were 2.4 times more likely to attain elite volleyball status, while all other districts decreased the odds of expert development. For men, being born in high-density areas resulted in less chance of achieving expertise, whereas there were no differences for women. The results suggest that athletes' infrastructure and social structure play an important role in talent development, and that these structures are influenced by total population and population density, respectively.

RESUMEN

The community size effect (or birthplace effect) suggests that high-performance athletes are less likely to emerge from regions with population sizes that are very small or very large. However, previous research on elite Canadian ice hockey players has not considered the influence of intra-national regional variation of population distributions with respect to community size effects. Therefore, the purpose of the current study was to test the heterogeneity of the community size effect between Canadian National Hockey League draftees (2000-2014: n = 1505), from 7 provincial regions within Canada (i.e., British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and the Atlantic Provinces). The proportion of athletes in the 9 census population categories were compared to the national and regional general population distributions in the census categories. Results suggest variability of community size effects between the 7 provincial regions within Canada, with only the province of Ontario demonstrating a community size effect congruent with effects reported in previous research. Using regional general population distributions as the comparator to athlete populations changed the direction, meaningfulness and magnitude of community size effects. In conclusion, elite ice hockey player community size effects may not be generalisable to all regions within Canada.

RESUMEN

BACKGROUND: Latinos born in the US, 36 million, comprise 65% of all US Latinos. Yet their cancer experience is nearly always analyzed together with their foreign-born counterparts, 19 million, who constitute a steady influx of truly lower-risk populations from abroad. To highlight specific cancer vulnerabilities for US-born Latinos, we compare their cancer mortality to the majority non-Latino white (NLW) population, foreign-born Latinos, and non-Latino blacks. METHODS: We analyzed 465,751 cancer deaths from 2008 to 2012 occurring among residents of California and Texas, the two most populous states, accounting for 47% of US Latinos. This cross-sectional analysis, based on granular data obtained from death certificates on cause of death, age, race, ethnicity and birthplace, makes use of normal standardization techniques and negative binomial regression models. RESULTS: While Latinos overall have lower all-cancers-combined mortality rates than NLWs, these numbers were largely driven by low rates among the foreign born while mortality rates for US-born Latinos approach those of NLWs. Among Texas males, rates were 210 per 100,000 for NLWs and 166 for Latinos combined, but 201 per 100,000 for US-born Latinos and 125 for foreign-born Latinos. Compared to NLWs, US-born Latino males in California had mortality rate ratios of 2.83 (95% CI: 2.52-3.18) for liver cancer, 1.44 (95% CI: 1.30-1.61) for kidney cancer, and 1.25 (95% CI: 1.17-1.34) for colorectal cancer (CRC). Texas results showed a similar site-specific pattern. CONCLUSIONS: Specific cancer patterns for US-born Latinos, who have relatively high cancer mortality, similar overall to NLWs, are masked by aggregation of all Latinos, US-born and foreign-born. While NLWs had high mortality for lung cancer, US-born Latinos had high mortality for liver, kidney and male colorectal cancers. HCV testing and reinforcement of the need for CRC screening should be a priority in this specific and understudied population. The unprecedented proximity of overall rates between NLWs and US-born Latino populations runs counter to the prevailing narrative of Latinos having significantly lower cancer risk and mortality. Birthplace data are critical in detecting meaningful differences among Latinos; these findings merit not only clinical but also public health attention.

RESUMEN

BACKGROUND: Maternal socioeconomic disparities strongly affect child health, particularly in low and middle income countries. We assessed whether neonatal outcomes varied by maternal education in a setting where healthcare system provides universal coverage of health services to all women, irrespective of their socioeconomic status. METHODS: A population-based study was performed on 383,103 singleton live births occurring from 2005 to 2010 in Lombardy, an Italian region with approximately 10 million inhabitants. The association between maternal education, birthplace and selected neonatal outcomes (preterm birth, low birth weight, small-for-gestational age, low 5-min Apgar score, severe congenital anomalies, cerebral distress and respiratory distress) was estimated by fitting logistic regression models. Model adjustments were applied for sociodemographic, reproductive and medical maternal traits. RESULTS: Compared with low-level educated mothers, those with high education had reduced odds of preterm birth (Odds Ratio; OR = 0.81, 95% CI 0.77-0.85), low birth weight (OR = 0.78, 95% CI 0.70-0.81), small for gestational age (OR = 0.82, 95% CI 0.79-0.85), and respiratory distress (OR = 0.84, 95% CI 0.80-0.88). Mothers born in a foreign country had higher odds of preterm birth (OR = 1.16, 95% CI 1.11-1.20), low Apgar score (OR = 1.18, 95% CI 1.07-1.30) and respiratory distress (OR = 1.19, 95% CI 1.15-1.24) than Italian-born mothers. The influence of maternal education on neonatal outcomes was confirmed among both, Italian-born and foreign-born mothers. CONCLUSIONS: Low levels of education and maternal birthplace are important factors associated with adverse neonatal outcomes in Italy. Future studies are encouraged to investigate factors mediating the effects of socioeconomic inequality for identifying the main target groups for interventions.

RESUMEN

AIM: To explore first-time pregnant women's expectations and factors influencing their choice of birthplace. BACKGROUND: Although outcomes and advantages for low-risk childbearing women giving birth in midwifery-led units and home compared with obstetric units have been investigated previously, there is little information on the factors that influence women's choice of place of birth. DESIGN: A qualitative Straussian grounded theory methodology was adopted. Fourteen women expecting their first baby were recruited from three large National Health Service organizations that provided maternity services free at the point of care. The three organizations offered the following birthplace options: home, freestanding midwifery unit and obstetric unit. Ethical approvals were obtained and informed consent was gained from each participant. METHODS: Data collection was undertaken in 2013-2014. One tape-recorded face-to-face semistructured interview was conducted with each woman in the third trimester of pregnancy. FINDINGS: Findings are presented as three main themes: (i) influencing factors on the choice of birthplace; (ii) expectations on the midwife's 'being' and 'doing' roles; (iii) perceptions of safety. CONCLUSION: Midwives should consider each woman's expectations and approach to birth beyond the planned birthplace, as these are often influenced by the intersection of various influencing factors. Several birthplace options should be made available to women in each maternity service and the alternatives should be shared with women by healthcare professionals during pregnancy to allow an informed choice. Virtual tours or visits to the birth units could also be offered to women to help them familiarize with the chosen setting.
