Neonatal outcomes in Syrian and other refugees treated in a tertiary hospital in Turkey

Exploring Predictors of Preterm Birth: A Comparative Study of Turkish and Syrian Refugee Women

OBJECTIVE

This study is designed to explore associated sociodemographic, birth-related and household characteristics with preterm birth (< 37 weeks) among Turkish and Syrian refugee women.

METHODS

The data utilized in this study were obtained from the Turkey Demographic and Health Survey (TDHS) conducted in 2018. Various statistical analyses, including descriptive statistics, independent sample t-tests, and Chi-square tests, were employed to examine the differences in study variables between Turkish and Syrian refugee women. Furthermore, logistic regression analysis was conducted to identify the associated factors with preterm birth among Turkish and Syrian refugee women, allowing for comparative analysis.

RESULTS

The key findings of this study revealed significant differences in sociodemographic (p < 0.05), birth-related (p < 0.05), and household characteristics (p < 0.05) that are associated with preterm birth among Turkish and Syrian refugee women. Also, nationality (OR: 3.427; 95% CI 2.770-4.241), delivery by c-section (OR: 1.630; 95% CI 1.370-1.939), educational status (OR: 0.674; 95% CI 0.547-0.832), place of delivery (OR: 0.806; 95% CI 0.666-0.975), and number of household members (OR: 1.206; 95% CI 1.013-1.437) were found to be important factors associated with preterm birth risk.

CONCLUSIONS

The key findings of this study contribute to the identification of women's factors in preterm birth. By understanding the factors that contribute to preterm birth among both Syrian refugee and Turkish women, appropriate interventions can be developed to improve maternal and child health outcomes.

Comparison of Perinatal Outcomes Between Syrian Refugees and Turkish Women in the Middle Anatolia Region of Turkey

OBJECTIVE

To compare the results of perinatal outcomes between Syrian refugees and Turkish women between 2016 and 2020.

METHODS

The birth results of 17,997 participants (Syrian refugees: 3579 and Turkish women: 14,418) who delivered in the Labor Department of our hospital between January 2016 and December 2020 were retrospectively analyzed.

RESULTS

Maternal age was younger (24.73 ± 6.08 vs. 27.4 ± 5.91 years, p < 0.001) and adolescent pregnancy rate was higher (19.4% vs. 5.6%, p < 0.001) in Syrian refuges than in Turkish women. Bishop scores on admission (4.6 ± 1.6 vs. 4.4 ± 1.1, p < 0.001), birth weight (3088.19 ± 575.32 g vs. 3109.76 ± 540.89 g, p = 0.044), low birth weight (11.3% vs. 9.7%, p = 0.004), and the rate of primary cesarean deliveries (10.1% vs. 15.8%, p < 0.001) were also statistically different. Additionally, the rates of anemia (65.9% vs. 29.2%, p < 0.001), preeclampsia (1.4% vs. 2.7%, p < 0.001), stillbirth (1.3% vs. 0.6%, p < 0.001), preterm premature rupture of membranes (2.7% vs. 1.9%, p = 0.002), and obstetric complications were different between the groups.

CONCLUSIONS

This study showed that inadequate antenatal care, communication and language barrier problems in Syrian refugees caused some adverse perinatal outcomes. All birth data of Syrian refugees must be disclosed by the Ministry of Health to confirm the accuracy of our data.

Disparities in Obstetric, Neonatal, and Birth Outcomes Among Syrian Women Refugees and Jordanian Women

Objectives: To compare obstetric and neonatal characteristics and birth outcomes between Syrian refugees and native women in Jordan. Methods: We used the Jordan Stillbirths and Neonatal Deaths Surveillance System to extract sociodemographic and obstetric characteristics of the mothers and birth characteristics of newborns. Multivariate analysis was used to compare the characteristics of 26,139 Jordanian women (27,468 births) and 3,453 Syrian women refugees (3,638 births) who gave birth in five referral hospitals (May 2019 and December 2020). Results: The proportions of low birthweight (14.1% vs. 11.8%, p < 0.001) and small for gestational age (12.0% vs. 10.0%, p < 0.001) newborns were significantly higher for those born to Syrian women compared to those born to Jordanian women. The stillbirth rate (15.1 vs. 9.9 per 1,000 births, p = 0.003), the neonatal death rate (21.2 vs. 13.2 per 1,000 live births, p < 0.001), and perinatal death rate (21.2 vs. 13.2 per 1,000 births, p < 0.001) were significantly higher for the Syrian births. After adjusting for sociodemographic and obstetric characteristics of women, only perinatal death was statistically significantly higher among Syrian babies compared to Jordanian babies (OR = 1.3, 95% CI: 1.1-1.7, p = 0.035). Conclusion: Syrian refugee mothers had a significantly higher risk of adverse obstetric and neonatal outcomes including higher rate of perinatal death compared to Jordanian women.

Perinatal and Neonatal Outcomes of Refugee Infants in a Tertiary Hospital in Turkey

Background Worldwide, the immigration problem has been increasing due to conflicts. In recent years, Turkey accepted more than 3.8 million refugees from many countries, principally Syria. Aims In this study, we aimed to evaluate the prenatal features and neonatal outcomes of refugees and Turkish controls hospitalized in a tertiary neonatal intensive care unit in Turkey. Materials and methods This retrospective case-control study included comparative data related to populations based on whether they were refugees or not. Their perinatal and neonatal "outcomes" were compared. Results Among the 254 analyzed neonates, 127 were born to refugee mothers, and 127 controls were born to non-refugee Turkish mothers. The refugee rate in our hospitalized neonates was nine, a young mother's age (p=0.010) with a higher rate of adolescent pregnancies at OR 2.78 (95% CI 0.96-8.05) (p=0.032), and consanguineous marriage at OR 0.57 (95% CI 0.32-1.02) (p=0.031) in comparison to non-refugees. The incidence of ABO incompatibility-related hemolytic jaundice (p=0.013) was higher in the refugees. The rate of formula feeding in the first month of life was significantly higher at OR 0.49 (95% CI 0.25-0.92) (p=0.027) in neonates born to refugee mothers. Despite lower perinatal care rates in refugees at OR 7.23 (95%CI 4.12-12.69) (<0.001), preterm morbidities did not differ between refugees and non-refugee preterm infants ≤32 gestational age (p>0.05). Conclusion The importance of breast milk must be strongly encouraged to initiate and promote exclusive breastfeeding for the infants of refugees. Race is still an important risk factor for ABO incompatibility-related hemolytic jaundice. Providing high-quality healthcare is sufficient to prevent worse outcomes in refugee neonates.

Adverse Pregnancy Outcomes and International Immigration Status: A Systematic Review and Meta-analysis

Background:

Disparities in health outcomes between immigrant and native-origin populations, particularly pregnant women, pose significant challenges to healthcare systems. The aim of this systematic-review and meta-analysis was to investigate the risk of adverse pregnancy outcomes among immigrant-women compared to native-origin women in the host country.

Methods:

PubMed (including MEDLINE), Scopus, and Web of Science were searched to retrieve studies published in English language up to September 2020. All observational studies examining the prevalence of at least one of the short-term single pregnancy outcomes for immigrants who crossed international borders compared to native-origin pregnant population were included. The meta-prop method was used for the pooled-estimation of adverse pregnancy-outcomes’ prevalence. For pool-effect estimates, the association between the immigration-status and outcomes of interest, the random-effects model was applied using the model described by DerSimonian and Laird. I² statistic was used to assess heterogeneity. The publication bias was assessed using the Harbord-test. Meta-regression was performed to explore the effect of geographical region as the heterogeneity source.

Findings:

This review involved 11 320 674 pregnant women with an immigration-background and 56 102 698 pregnant women as the native-origin population. The risk of emergency cesarean section (Pooled-OR = 1.1, 95%CI = 1.0–1.2), shoulder dystocia (Pooled-OR = 1.1, 95%CI = 1.0–1.3), gestational diabetes mellites (Pooled-OR = 1.4, 95%CI = 1.2–1.6), small for gestational age (Pooled-OR=1.3, 95%CI = 1.1–0.4), 5-min Apgar less than 7 (Pooled-OR = 1.2, 95%CI = 1.0–1.3) and oligohydramnios (Pooled-OR = 1.8, 95%CI = 1.0–3.3) in the immigrant women were significantly higher than those with the native origin background. The immigrant women had a lower risk of labor induction (Pooled-OR = 0.8, 95%CI = 0.7–0.8), pregnancy induced hypertension (Pooled-OR = 0.6, 95%CI = 0.5–0.7) preeclampsia (Pooled-OR = 0.7, 95%CI = 0.6–0.8), macrosomia (Pooled-OR = 0.8, 95%CI = 0.7–0.9) and large for gestational age (Pooled-OR = 0.8, 95%CI = 0.7–0.8). Also, the risk of total and primary cesarean section, instrumental-delivery, preterm-birth, and birth-trauma were similar in both groups. According to meta-regression analyses, the reported ORs were not influenced by the country of origin.

Conclusion:

The relationship between the immigration status and adverse perinatal outcomes indicated a heterogenous pattern, but the immigrant women were at an increased risk of some important adverse pregnancy outcomes. Population-based studies with a focus on the various aspects of this phenomena are required to explain the source of these heterogenicities.

A Systematic Review and Meta-Analysis of the Risk of Stillbirth, Perinatal and Neonatal Mortality in Immigrant Women

Objectives: This study aimed to investigate the risk of stillbirth, perinatal and neonatal mortality in immigrant women compared to native-origin women in host countries. Methods: A systematic literature review and meta-analysis was conducted. Relevant studies were identified using a thorough literature search and their quality was appraised. The analysis of heterogeneous data was carried out using the random effects model and publication bias was assessed using the Harbord-test. Also, the pooled odds ratio of events was calculated through the DerSimonian and Laird, and inverse variance methods. Results: In the search process 45 studies were retrieved consisting of 8,419,435 immigrant women and 40,113,869 native-origin women. The risk of stillbirth (Pooled OR = 1.35, 95% CI = 1.22-1.50), perinatal mortality (Pooled OR = 1.50, 95% CI = 1.35-1.68), and neonatal mortality (Pooled OR = 1.09, 95% CI = 1.00-1.19) in the immigrant women were significantly higher than the native-origin women in host countries. According to the sensitivity analyses, all results were highly consistent with the main data analysis results. Conclusion: The immigrant women compared to the native-origin women had the higher risks of stillbirth, perinatal and neonatal mortality. Healthcare providers and policy makers should improve the provision of maternal and neonatal healthcare for the immigrant population.

Perinatal and Neonatal Outcomes in Immigrants From Conflict-Zone Countries: A Systematic Review and Meta-Analysis of Observational Studies

Objectives

There are controversies regarding the risk of adverse pregnancy outcomes among immigrants from conflict-zone countries. This systematic review and meta-analysis aimed to investigate the risk of perinatal and neonatal outcomes among immigrants from conflict-zone countries compared to native-origin women in host countries.

Methods

A systematic search on the databases of PubMed/MEDLINE, Scopus, and Web of Science was carried out to retrieve studies on perinatal and neonatal outcomes among immigrants from Somalia, Iraq, Afghanistan, Yemen, Syria, Nigeria, Sudan, Ethiopia, Eritrea, Kosovo, Ukraine, and Pakistan. Only peer-reviewed articles published in the English language were included in the data analysis and research synthesis. The odds ratio and forest plots were constructed for assessing the outcomes of interests using the DerSimonian and Laird, and the inverse variance methods. The random-effects model and the Harbord test were used to account for heterogeneity between studies and assess publication bias, respectively. Further sensitivity analysis helped with the verification of the reliability and stability of our review results.

Results

The search process led to the identification of 40 eligible studies involving 215,718 pregnant women, with an immigration background from the conflict zone, and 12,806,469 women of native origin. The adverse neonatal outcomes of the risk of small for gestational age (Pooled OR = 1.8, 95% CI = 1.6, 2.1), a 5-min Apgar score <7 (Pooled OR = 1.4, 95% CI = 1.0, 2.1), stillbirth (Pooled OR = 1.9, 95% CI = 1.2, 3.0), and perinatal mortality (Pooled OR = 2, 95% CI = 1.6, 2.5) were significantly higher in the immigrant women compared to the women of native-origin. The risk of maternal outcomes, including the cesarean section (C-S) and emergency C-S, instrumental delivery, preeclampsia, and gestational diabetes was similar in both groups.

Conclusion

Although the risk of some adverse maternal outcomes was comparable in the groups, the immigrant women from conflict-zone countries had a higher risk of neonatal mortality and morbidity, including SGA, a 5-min Apgar score <7, stillbirth, and perinatal mortality compared to the native-origin population. Our review results show the need for the optimization of health care and further investigation of long-term adverse pregnancy outcomes among immigrant women.

Neonatal morbidity among African refugee women in Israel: a case-control study

OBJECTIVES

Reports on neonatal morbidity (NM) among refugees in developed countries remain inconsistent. We aimed to compare NM among infants of African refugees in Israel to the native population based on a large population sample.

DESIGN

A case-control study.

SETTING

A tertiary hospital in Israel.

PARTICIPANTS

Data on hospital-based live births of refugee women and their newborns who were born in 2014 and 2017 were retrieved from medical records. Perinatal and neonatal data were compared between the refugee group and the native residents matched for gestational age and year of birth as well as within the refugee group.

PRIMARY OUTCOME

Prevalence of NM among African refugees in Israel.

RESULTS

Newborns delivered by 357 refugee women (mean age 30.2 years) and 357 controls (mean age 32.2 years) were analysed. Both groups were similar for the newborns' weight and gestational age. There were no significant differences in NM between the groups. A within-refugee comparison conducted between 2014 and 2017 yielded significant differences in birth weight (3051.4 vs 3373.6 gr, p<0.001, 95% CI (198.3 to 446.2), d=0.56), the number of twin deliveries (10 vs 4, p=0.002, Φ=0.173), the number of neonates evaluated as small for gestational age (15 vs 10, p=0.003, Φ=0.167) and the use of human milk (71% vs 93%, p<0.001, Φ=-0.298).

CONCLUSIONS

We conclude that NM among neonates born to refugee mothers was not higher than that of neonates born to native Israeli mothers. We suggest that successful implementation of health policies for refugees has improved their accessibility to mother-child health services.

Comparison of Clinical Characteristics and Pregnancy and Neonatal Outcomes Between Turkish Citizens and Syrian Refugees with High-Risk Pregnancies

Refugee women experience more negative pregnancy and neonatal outcomes, such as low birth weight and preterm birth. The aim of the present study was to compare the clinical characteristics and pregnancy and neonatal outcomes between Turkish citizens and Syrian refugees with high-risk pregnancies. This prospective cohort study was conducted between March and December 2020 in Sanliurfa, Turkey. The maternal characteristics and pregnancy and neonatal outcomes were compared between the two groups. In this study, a total of 302 high-risk pregnant women (233 Turkish citizens and 69 Syrian refugees) were included. Parity and pregnancy spacing shorter than 2 years were significantly higher in Syrian refugees. Age, previous abortion or miscarriage and rates of cesarean section (C/S) were significantly higher in Turkish citizens. The live birth (Turkish: 94.8% vs Syrian: 92.8%), preterm birth (Turkish: 10% vs Syrian: 9.4%), low birth weight (Turkish: 7.7% vs Syrian: 3.1%) rates and birth weight (g) (Turkish: 3097.5 ± 501.3 g; Syrian: 2980.2 ± 395.0 g) were not significantly different between Turkish citizens and Syrian refugees with high-risk pregnancy. Similar pregnancy and neonatal outcomes could be attributed to the Syrians receiving adequate and free maternity care, similar to the Turkish citizens.

[A unique population in today's paediatric intensive care unit: Immigrant children presenting with infectious diseases]

INTRODUCTION

Despite similar disease severity scores; we found a higher crude death rate in the group of immigrant children compared to the group of native children in a paediatric intensive care unit. Our study aimed to compare descriptive data and standardised mortality ratios (SMR) in order to analyse differences in mortality.

MATERIAL AND METHODS

We conducted a retrospective study comparing demographic characteristics, diagnostic data, disease severity scores and mortality in immigrant children of Syrian descent and children of Turkish descent. We included data for the medical and surgical patients admitted in 1 year. The sample included 1283 patients.

RESULTS

We compared the age and sex distribution, presence of underlying disease, frequency of community-acquired infectious diseases, length of say, PRISM scores, SMR and crude death rates in the 2 groups. There were 1077 patients in the Turkish group and 206 patients in the immigrant group. The proportion of patients with underlying disease was greater in the Turkish group (42% vs. 37.4%). The proportion of patients with a community-acquired infectious disease as the presenting complaint was similar in both groups (52.9% vs. 47.4%). The mortality in patients with infectious disease was higher in the immigrant group (19.3% vs. 9.8%). There was not significant difference in the mean PRISM score between the 2 groups. We found a higher mortality in the immigrant group (16% vs. 11%). The standardised mortality ratio was 0.32 in the total sample group; 0.4 in the immigrant group and 0.24 in the Turkish group.

CONCLUSIONS

In our study, we found an association between community-acquired infectious disease and increased mortality in the immigrant group. The underlying mechanism for this increase remains to be explained and further research is required to determine whether parameters related to infection should be added to this severity score for its use in this specific population.
