Abstract
Robust epidemiological evidence of risk and protective factors for psychosis is essential to inform preventive interventions. Previous evidence syntheses have classified these risk and protective factors according to their strength of association with psychosis. In this critical review we appraise the distinct and overlapping mechanisms of 25 key environmental risk factors for psychosis, and link these to mechanistic pathways that may contribute to neurochemical alterations hypothesised to underlie psychotic symptoms. We then discuss the implications of our findings for future research, specifically considering interactions between factors, exploring universal and subgroup-specific factors, improving understanding of temporality and risk dynamics, standardising operationalisation and measurement of risk and protective factors, and developing preventive interventions targeting risk and protective factors.

Abstract
The international literature review highlights higher neonatal morbimortality in migrant patients and their babies. The explanatory hypotheses include late pregnancy follow-up with difficulty accessing care, language barriers, and different cultural representation in pregnancy support. On the one hand, we propose to explain the cultural factors that can impact the caring relationship during the perinatal period. On the other hand, we set out tools for anthropological and psychological understanding to enhance the sharing of cultural representations around pregnancy follow-up, the needs of a baby, and obstetrical or postnatal complications. The request for a specialised transcultural opinion needs to be more systematic; the transcultural posture is adaptable to each care professional. This requires the professional to address explicitly the impact of culture in care and consider their own cultural distance. Specialised advice is recommended in certain situations of cumulative vulnerability (complex trauma, perinatal depression with cultural coding of symptoms), blockage or refusal of care for cultural reasons and to avoid cultural misunderstandings. We detail two modalities: mediation and a discussion group around cultural issues set up in the maternity ward. The institutional work we propose within the multidisciplinary team in the maternity ward also allows the acquisition of transcultural competencies.

Abstract
Purpose: The reproductive health outcomes of international migrant women differ in comparison with receiving-country-born women, depending on country of birth and immigrant status. Effective interventions to support the reproductive health of international migrant women are not well known. Methods: We conducted a systematic review and meta-analysis of studies between 2010 and 2017 evaluating interventions directly or indirectly affecting the reproductive health (as defined by the World Health Organization) of international migrant women in Western-receiving countries. Results: Sixteen studies representing 5080 migrants were identified. Interventions consisted of linguistically (e.g., translated brochures) or culturally adapted (e.g., cultural narratives) routine care or new interventions. Meta-analysis showed that interventions increased rates of preventive reproductive health activities, including mammography, condom use, and Pap test completion, by almost 18% (95% confidence interval 7.61–28.3) compared with usual care or interventions not adapted to migrant women. Conclusion: Culturally and linguistically adapted care practices congruent with target populations of international migrant women are effective in improving their reproductive health outcomes, particularly their participation in preventative reproductive health activities.

Placental weight in first generation migrant mothers in Germany. Do the length of stay, acculturation or migrant status play a role? Placenta 2021; 108:103-108. [PMID: 33857818 DOI: 10.1016/j.placenta.2021.03.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 03/21/2021] [Accepted: 03/23/2021] [Indexed: 01/31/2023]
Abstract
INTRODUCTION Migration status affects perinatal outcomes. A small placenta is associated with placental dysfunction and poor outcomes. Placental weight and perinatal outcomes are influenced by migrant status, the length of stay and the level of acculturation in the host country. Our aim was to compare placental weight in first generation immigrants to native non-immigrants in a teaching hospital in Berlin. The influence of migrant status, the length of stay and the level of acculturation on placental weight was also ascertained. METHODS At the Charité University Hospital in Berlin Germany between January 2011 and January 2012, 1373 non-migrant and 1243 first generation migrants were included. Data collection was by means of a standardized questionnaire. The level of acculturation was based on the Frankfurter Acculturation Questionnaire (Frankfurter Akkulturationsfragebogen-FRAKK). Demographic parameters such as age, maternal weight, country of origin, parity, anemia, diabetes, hypertension, smoking and neonatal outcomes including neonatal weight, placental weight were measured. RESULTS We found no difference in mean placenta weight when comparing first generation women with a migration background to women of the native population (608 g vs 597 g, p-value 0.41). There was also no difference in placental weight when assessed by the length of stay and degree of acculturation in the host country. DISCUSSION While first generation migrant women have increased perinatal complications, there is no influence of migrant status, length of stay and the degree of acculturation on placenta weight. Pregnancy outcomes maybe be more dependent on factors such as the access to adequate maternal care.

Abstract
PURPOSE To investigate the proportion of severely growth-restricted singleton births < 3rd percentile (proxy for severe fetal growth restriction; FGR) undelivered at 40 weeks (FGR_40), and compare maternal characteristics and outcomes of FGR_40 births and FGR births at 37-39 weeks' (FGR_37-39) to those not born small-for-gestational-age at term (Not SGA_37+). METHODS The annual rates of singleton FGR_40 births from 2006 to 2015 were calculated using data from linked Western Australian population health datasets. Using 2013-2015 data, maternal factors associated with FGR births were investigated using multinomial logistic regression to estimate odds ratios (OR) with 95% confidence intervals (CI) while relative risks (RR) of birth outcomes between each group were calculated using Poisson regression. Neonatal adverse outcomes were identified using a published composite indicator (diagnoses, procedures and other factors). RESULTS The rate of singleton FGR_40 births decreased by 23.0% between 2006 and 2015. Factors strongly associated with FGR_40 and FGR_37-39 births compared to Not SGA_37+ births included the mother being primiparous (ORs 3.13: 95% CI 2.59-3.79; 1.69, 95% CI 1.47, 1.94, respectively) and ante-natal smoking (ORs 2.55, 95% CI 1.97, 3.32; 4.48, 95% CI 3.74, 5.36, respectively). FGR_40 and FGR_37-39 infants were more likely to have a neonatal adverse outcome (RRs 1.70, 95% CI 1.41, 2.06 and 2.46 95% CI 2.18, 2.46, respectively) compared to Not SGA 37+ infants. CONCLUSIONS Higher levels of poor perinatal outcomes among FGR births highlight the importance of appropriate management including fetal growth monitoring. Regular population-level monitoring of FGR_40 rates may lead to reduced numbers of poor outcomes.

Abstract
Background To compare the prevalence of preterm birth, post term birth, intra-uterine growth restriction and distribution of Apgar scores in offspring of foreign-born women in Western Australia with that of their Australian-born non-Indigenous and Indigenous counterparts. Methods A population-based linked data study, involving 767,623 singleton births in Western Australia between 1980 and 2010 was undertaken. Neonatal outcomes included preterm birth, post term births, intra-uterine growth restriction (assessed using the proportion of optimal birth weight) and low Apgar scores. These were compared amongst foreign-born women from low, lower-middle, upper middle and high income countries and Australian-born non-Indigenous and Indigenous women over two different time periods using multinomial logistic regression adjusted for covariates. Results Compared with Australian born non-Indigenous women, foreign-born women from low income countries were at some increased risk of extreme preterm (aRRR 1.59, 95% CI 0.87, 2.89) and very early preterm (aRRR 1.63, 95% CI 0.92, 2.89) births during the period from 1980 to 1996. During the period from 1997 to 2010 they were also at some risk of extreme preterm (aRRR 1.42, 95% CI 0.98, 2.04) very early preterm (aRRR 1.34, 95% CI 1.11, 1.62) and post term birth (aRRR 1.93, 95% CI 0.99, 3.78). During this second time period, other adverse outcomes for children of foreign-born women from low income and middle income countries included increases in severe (aRRR 1.69, 95% CI 1.30, 2.20; aRRR 1.72, 95% CI 1.53, 1.93), moderate (aRRR 1.54, 95% CI 1.32, 1.81; aRRR 1.59, 95% CI 1.48, 1.70) and mild (aRRR 1.28, 95% CI 1.14, 1.43; aRRR 1.31, 95% CI 1.25, 1.38) IUGR compared to children of Australian-born non-Indigenous mothers. Uniformly higher risks of adverse outcomes were also demonstrated for infants of Indigenous mothers. Conclusions Our findings illustrate the vulnerabilities of children born to foreign women from low and middle-income countries. The need for exploratory research examining mechanisms contributing to poorer birth outcomes following resettlement in a developed nation is highlighted. There is also a need to develop targeted interventions to improve outcomes for these women and their families.

BMC Pregnancy Childbirth 2019; 19:217. [PMID: 31248386 PMCID: PMC6598349 DOI: 10.1186/s12884-019-2364-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Accepted: 06/14/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In many Western countries, higher rates of cesarean have been described among migrant women compared to natives of receiving countries. We aimed to estimate this difference comparing women originating from France and Sub-Saharan Africa (SSA), identify the clinical situations explaining most of this difference and assess whether maternal origin was independently associated with cesarean risk. METHODS The PreCARE prospective multicenter cohort study was conducted in 2010-2012 in the north Paris area. Our sample was restricted to 1500 women originating from Sub-Saharan Africa and 2206 from France. Profiles of cesarean section by maternal origin were described by the Robson classification. Independent associations between maternal origin and 1) cesarean before labor versus trial of labor, then 2) intrapartum cesarean versus vaginal delivery were assessed by logistic regression models to adjust for other maternal and pregnancy characteristics. RESULTS Rates of cesarean for women originating from France and SSA were 17 and 31%. The Robson 5A category "unique uterine scar, single cephalic ≥37 weeks" was the main contributor to this difference. Within this category, SSA origin was associated with cesarean before labor after adjustment for medical risk factors (adjusted odds ratio [aOR] = 2.30 [1.12-4.71]) but no more significant when adjusting on social deprivation (aOR = 1.45 [0.63-3.31]). SSA origin was associated with cesarean during labor after adjustment for both medical and social factors (aOR = 2.95 [1.35-6.44]). CONCLUSIONS The wide difference in cesarean rates between SSA and French native women is mainly explained by the Robson 5A category. Within this group, medical factors alone do not explain the increased risk of cesarean in SSA women.

Abstract
OBJECTIVES To evaluate the prevalence and risks of developmental disability (autism spectrum disorder, intellectual disability, and cerebral palsy) in Western Australian children of different groups of foreign-born women. STUDY DESIGN Western Australian population-based linked data of 764 749 singleton live births from 1980 to 2010 were used to compare disability outcomes among children of foreign-born, Australian-born non-Indigenous, and Indigenous women. The risk of disability was assessed using multinomial logistic regression. RESULTS Overall, the prevalence of any disability was lowest for the children of foreign-born mothers. From 1980 to 1996 but not from 1997 to 2010, children born to mothers from foreign-born low-income countries had an increased relative risk of autism spectrum disorder with intellectual disability, and children born to foreign-born mothers from upper-middle-income countries had an increased risk of cerebral palsy with intellectual disability. After adjusting for smoking, the relative risks of intellectual disability and cerebral palsy with intellectual disability were markedly decreased in children of Australian-born Indigenous mothers. CONCLUSIONS Although we did not find among children born to foreign-born women an increased prevalence across all the measured developmental outcomes, we did observe an increased risk of autism spectrum disorder with intellectual disability and cerebral palsy with intellectual disability for mothers of some foreign-born groups. Our findings related to smoking in the Indigenous population underscore its possible role on the causal pathway to intellectual disability. Maternal migration is considered a factor on the causal pathway to intellectual disability. Maternal migration may be either a risk or a protective factor on the causal pathway to developmental disabilities and the direct role of migration is inconclusive in our study.

Abstract
Introduction
Perinatal data of women with a Vietnamese migration background have not been systematically studied in Germany to date. Numerous details of important maternal and child outcomes were compared and analysed. The studyʼs primary parameters were the frequency of and indication for c-section.
Methodology
The perinatal data from a Berlin hospital were analysed retrospectively. The women (Vietnamese migration background vs. autochthonous) were grouped using name analysis. Datasets of 3002 women giving birth, including 999 women with a Vietnamese migration background, were included. The associations between primary or secondary cesarean delivery and different child outcomes depending on the migration background (exposure) were studied using logistical regression analysis.
Results
Women with a Vietnamese migration background have a lower c-section rate of 8.0% for primary and 12.6% for secondary c-section than women without a migration background (11.1% primary and 16.4% secondary c-section respectively). Regression analysis shows that the odds that women with a Vietnamese migration background will have a primary (OR 0.75; p = 0.0884) or secondary c-section (OR 0.82; p = 0.1137) are not significantly lower. A Vietnamese migration background was associated with higher odds for an episiotomy but not for a grade 3 – 4 perineal tear. A Vietnamese migration background does not have a significant influence on poor 5-min Apgar scores ≤ 7 and low umbilical cord arterial pH values ≤ 7.10. Newborns of mothers with a Vietnamese migration background have higher odds of a relatively higher birth weight (> 3110 g).
Summary
There was no evidence that women with a Vietnamese migration background are delivered more often by caesarean section. There were also no differences as regards important child outcome data from women in the comparator group. Overall, the results do not provide any evidence for poorer quality of care of women with a Vietnamese migration background in Berlin despite the cultural and communication barriers in the reality of care provision.

Abstract
BACKGROUND Uterine tachysystole (more than 5 contractions per 10 minutes in 2 consecutive intervals) is common during labour, particularly with use of labour-stimulating agents. Tachysystole may reduce fetal oxygenation by interrupting maternal blood flow to the placenta during contractions. Reducing uterine contractions may improve placental blood flow, improving fetal oxygenation. This review aimed to evaluate the use of tocolytics to reduce or stop uterine contractions for improvement of the condition of the fetus in utero. This new review supersedes an earlier Cochrane Review on the same topic. OBJECTIVES To assess the effects of the use of acute tocolysis during labour for uterine tachysystole or suspected fetal distress, or both, on fetal, maternal and neonatal outcomes. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (2 February 2018), and reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) evaluating acute tocolysis for uterine tachysystole, intrapartum fetal distress, or both. DATA COLLECTION AND ANALYSIS We used standard methods expected by Cochrane. MAIN RESULTS We included eight studies (734 women), conducted in hospital settings, predominantly in high-income countries (USA, Austria, Uruguay). Two trials were conducted in upper and lower middle-income countries (South Africa, Sri Lanka). The hospital facilities all had the capacity to perform caesarean section. Overall, the studies had a low risk of bias, except for methods to maintain blinding. All of the trials used a selective beta2 (ß2)-adrenergic agonist in one arm, however the drug used varied, as did the comparator. Limited information was available on maternal outcomes.Selective ß2-adrenergic agonist versus no tocolytic agent, whilst awaiting emergency deliveryThere were two stillbirths, both in the no tocolytic control group (risk ratio (RR) 0.23, 95% confidence interval (CI) 0.01 to 4.55; 2 studies, 57 women; low-quality evidence). One had gross hydrocephalus and the second occurred with vaginal delivery after waiting 55 minutes for caesarean section. The decision for caesarean section delivery was an inclusion criterion in both studies so we could not assess this as an outcome under this comparison. Abnormal fetal heart trace is probably lower with tocolytic treatment (RR 0.28, 95% CI 0.08 to 0.95; 2 studies, 43 women; moderate-quality evidence). The effects on the number of babies with Apgar score below seven were uncertain (low-quality evidence).Intravenous (IV) atosiban versus IV hexoprenaline (1 study, 26 women) One infant in the hexoprenaline group required > 24 hours in the neonatal intensive care unit (NICU) following a forceps delivery (RR 0.33, 95% CI 0.01 to 7.50; low-quality evidence). There were no fetal or neonatal mortalities and no Apgar scores below seven. There was one caesarean delivery in the IV hexoprenaline group (RR 0.33, 95% CI 0.01 to 7.50; low-quality evidence), and one case of abnormal fetal heart score in the atosiban group (RR 3.00, 95% CI 0.13 to 67.51; very low-quality evidence).IV fenoterol bromhydrate versus emergency delivery (1 study, 390 women) No data were reported for perinatal death, severe morbidity or fetal or neonatal mortality. IV fenoterol probably increases the risk of caesarean delivery (RR 1.12, 95% CI 1.04 to 1.22; moderate-quality evidence). Fenoterol may have little or no effect on the risk of Apgar scores below seven (RR 1.28, 95% CI 0.35 to 4.68; low-quality evidence).IV hexoprenaline versus no tocolytic agent, whilst awaiting emergency delivery (1 study, 37 women) No data were reported for perinatal death or severe morbidity. There were two fetal deaths in the no tocolytic control group (RR 0.23, 95% CI 0.01 to 4.55; low-quality evidence). The rate of caesarean delivery was not reported. There were two babies with Apgar scores below seven in the control group and none in the hexoprenaline group (RR 0.24, 95% CI 0.01 to 4.57; 35 women; low-quality evidence).Subcutaneous terbutaline versus IV magnesium sulphate (1 study, 46 women)No data were reported for perinatal death, severe morbidity or fetal or neonatal mortality. The decision for caesarean section was an inclusion criterion, so we could not assess this. The effects on abnormal fetal heart trace are uncertain (very low-quality evidence).Subcutaneous terbutaline with continuation of oxytocic infusion versus cessation of oxytocic infusion without tocolytic agent (1 study, 28 women) No data were reported for perinatal death, severe morbidity or fetal or neonatal mortality. There may be little or no difference in the rates of caesarean delivery in the subcutaneous terbutaline (8/15) and control groups (4/13) (RR 1.73, 95% CI 0.68 to 4.45; low-quality evidence). There were no cases of Apgar scores below seven or abnormal fetal heart trace.Subcutaneous terbutaline versus no tocolytic agent, whilst awaiting emergency delivery (1 study, 20 women) No data were reported for perinatal death or severe morbidity. There were no fetal or neonatal mortalities. The decision for caesarean section was an inclusion criterion, so we could not assess this. There were two babies with Apgar scores below seven in the control group and none in the terbutaline group (RR 0.17, 95% CI 0.01 to 3.08; low-quality evidence).IV terbutaline versus IV nitroglycerin (1 study, 110 women)No data were reported for perinatal death or severe morbidity or fetal or neonatal mortality. There may be little or no difference in the rates of caesarean delivery between the IV terbutaline (30/57) and control groups (29/53) (RR 0.96, 95% CI 0.68 to 1.36; low-quality evidence). There were no cases of Apgar scores below seven. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the effects of tocolytics for uterine tachysystole or suspected fetal distress during labour. The clinical significance for some of the improvements in measures of fetal well-being with tocolytics is unclear. The sample sizes were too small to detect effects on neonatal morbidity, mortality or serious adverse effects. The majority of studies are from high-income countries in facilities with access to caesarean section, which may limit the generalisability of the results to lower-resource settings, or settings where caesarean section is not available.Further well-designed and adequately powered RCTs are required to evaluate clinically relevant indicators of maternal and neonatal morbidity and mortality.

Abstract
OBJECTIVE To examine trends in caesarean section deliveries and factors associated with these trends for Indigenous and non-Indigenous mothers. DESIGN Total population-based study. SETTING Northern Territory of Australia, 1986-2012. POPULATION Pregnancies among Northern Territory residents, limited to singleton live births with cephalic presentations delivered at 37-42 weeks' gestation (n = 78 561). METHODS Descriptive analyses of demographic and obstetric risk factors. Poisson regression with robust variance to estimate the likelihood of caesarean delivery with and without labour compared with vaginal delivery, over time and between Indigenous and non-Indigenous mothers, adjusting for risk factors. MAIN OUTCOME MEASURES Trends in caesarean sections and risk of caesarean delivery compared with vaginal delivery. RESULTS The total rate of caesarean deliveries in the Northern Territory increased between 1986 and 2012. From the year 2000, the rise was driven by increases in caesareans with labour among nulliparous mothers and no labour caesareans among multiparous mothers. Increases in demographic and obstetric risk factors explained the rise in caesareans with labour among nulliparous Indigenous mothers, whereas other unmeasured variables contributed to the rise among non-Indigenous mothers. Increases in previous caesarean delivery contributed to the rise in all caesareans among multiparous mothers. Following adjustment, the risk of Indigenous nulliparous mothers having a caesarean with labour was 47% greater than for non-Indigenous nulliparous mothers [adjusted risk ratio 1.47 (95% CI 1.34-1.60)]. CONCLUSIONS Increases in demographic and obstetric risk factors partially explained the increase in caesarean rates in the Northern Territory and the contribution of these factors differed between Indigenous and non-Indigenous mothers. TWEETABLE ABSTRACT Caesarean section rates increased between 1986 and 2012 in the Northern Territory of Australia.

Abstract
High caesarean birth rates among migrant women living in high-income countries are of concern. Women from sub-Saharan Africa and South Asia consistently show overall higher rates compared with non-migrant women, whereas women from Latin America and North Africa/Middle East consistently show higher rates of emergency caesarean. Higher rates are more common with emergency caesareans than with planned caesareans. Evidence regarding risk factors among migrant women for undergoing a caesarean birth is lacking. Research suggests that pathways leading to caesarean births in migrants are complex, and they are likely to involve a combination of factors related to migrant women's physical and psychological health, their social and cultural context and the quality of their maternity care. Migration factors, including length of time in receiving country and migration classification, have an influence on delivery outcome; however, their effects appear to differ by women's country/region of origin.

Caesarean Section Frequency among Immigrants, Second- and Third-Generation Women, and Non-Immigrants: Prospective Study in Berlin/Germany. PLoS One 2015; 10:e0127489. [PMID: 25985437 PMCID: PMC4435809 DOI: 10.1371/journal.pone.0127489] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2014] [Accepted: 02/10/2015] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE The frequency of caesarean section delivery varies between countries and social groups. Among other factors, it is determined by the quality of obstetrics care. Rates of elective (planned) and emergency (in-labor) caesareans may also vary between immigrants (first generation), their offspring (second- and third-generation women), and non-immigrants because of access and language barriers. Other important points to be considered are whether caesarean section indications and the neonatal outcomes differ in babies delivered by caesarean between immigrants, their offspring, and non-immigrants. METHODS A standardized interview on admission to delivery wards at three Berlin obstetric hospitals was performed in a 12-month period in 2011/2012. Questions on socio-demographic and care aspects and on migration (immigrated herself vs. second- and third-generation women vs. non-immigrant) and acculturation status were included. Data was linked with information from the expectant mothers' antenatal records and with perinatal data routinely documented in the hospital. Regression modeling was used to adjust for age, parity and socio-economic status. RESULTS The caesarean section rates for immigrants, second- and third-generation women, and non-immigrant women were similar. Neither indications for caesarean section delivery nor neonatal outcomes showed statistically significant differences. The only difference found was a somewhat higher rate of crash caesarean sections per 100 births among first generation immigrants compared to non-immigrants. CONCLUSION Unlike earlier German studies and current studies from other European countries, this study did not find an increased rate of caesarean sections among immigrants, as well as second- and third-generation women, with the possible exception of a small high-risk group. This indicates an equally high quality of perinatal care for women with and without a migration history.

Comparison of Perinatal Data of Immigrant Women of Turkish Origin and German Women - Results of a Prospective Study in Berlin. Geburtshilfe Frauenheilkd 2014; 74:441-448. [PMID: 25089056 DOI: 10.1055/s-0034-1368489] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2013] [Revised: 02/24/2014] [Accepted: 02/25/2014] [Indexed: 10/25/2022] Open
Abstract
Aims: The aim of the study was to compare obstetrical process indicators and outcomes for German women with women of Turkish origin residing in Germany. Do women of Turkish origin attend antenatal examinations as frequently as non-immigrant women? Are high-risk pregnancies and anemia more common among immigrant women? Are the rates for epidural analgesia (PDA) and combined spinal-epidural analgesia (CSE) during delivery the same for immigrant women compared to German women? Are there identifiable differences in the mode of delivery and in perinatal outcomes? Patient Population/Methods: Data were obtained from 3 maternity clinics in Berlin for the period 2011 to 2012. The questionnaires covered socio-demographic factors and information on prenatal care as well as immigration/acculturation. The data obtained from these questionnaires was supplemented by information obtained from the official maternal record of prenatal and natal care (Mutterpass) and perinatal data recorded by the clinic. Results: The response rate was 89.6 %; the data of 1277 women of Turkish origin who had immigrated to Germany or whose family had immigrated and of 2991 non-immigrant women in Germany were included in the study. Regression analysis showed no statistically significant difference in the number of antenatal examinations between immigrant and non-immigrant women. Women of Turkish origin born in Germany had a significantly higher risk of postpartum anemia. PDA/CSE rate, arterial umbilical cord pH and 5-minute Apgar scores did not differ. The incidence of cesarean sections (elective and secondary) was significantly lower in the population of immigrant women of Turkish origin. Conclusion: Outcomes for most perinatal parameters were comparable for immigrant and non-immigrant women. These results indicate that the achieved standards of antenatal care and medical care during pregnancy are similar for Turkish immigrant women compared to non-immigrant women in maternity clinics in Berlin. The higher rates of anemia among immigrant women should be targeted by preventive measures.
