Maternal and newborn health inequality among Syrian refugees in Turkey: a systematic review and meta-analysis

OpenAlex İngilizce

OBJECTIVE: In this meta-analysis we explore significant health disparities in maternal and newborn health among Syrian refugees residing in Turkey. METHOD: The study protocol was registered in PROSPERO. We conducted a comprehensive literature search across six databases, including sources in English and Turkish, as well as relevant UN agencies, covering the period from 2011 (the onset of the Syrian conflict) to September 2024. This research specifically targets Syrian mothers aged 15 to 49 who were either pregnant or had recently given birth in Turkey, including studies with observational cross-sectional or retrospective designs. The quality of the included studies was evaluated using the JBI Critical Appraisal Checklist. Statistical analyses were performed using R version 4.4.1. RESULT: Of 382 studies in English and Turkish, 29 papers, 2 reports and 1 postgraduate thesis were selected for full-text evaluation. Syrian migrants were more at risk of anemia in the third trimester of pregnancy [RR: 2.27 (95% CI: 1.57 to 3.32)], and had less access to antenatal care [RR: 0.39 (95% CI: 0.26 to 0.58)] and iron supplementation during pregnancy [RR: 0.69 (95% CI: 0.46 to 0.96)] compared to the native population. The risks of adolescent pregnancy [RR: 3.78 (95% CI: (3.06 to 4.88)] and home birth [RR: 3.68 (95% CI: (2.53 to 5.27)] were higher among migrants [RR: 3.78 (95% CI: (3.06to 4.88)]. Conversely, migration was an important factor in gestational diabetes [RR: 0.44 (95% CI: (0.21 to 0.90)] and newborn macrosomia [RR: 0.54 (95% CI: (0.50 to 0.58)] as well as preeclampsia [RR: 0.56 (95% CI: (0.32 to 0.98)]. CONCLUSION: Our data revealed that Syrian migrant mothers face a higher risk of anemia, limited access to antenatal care and iron supplements, and higher rates of adolescent pregnancies and home births compared to their native counterparts. However, migration appears to have a protective effect on gestational diabetes and preeclampsia. The results underscore the need for targeted health interventions and policies that address access to maternal healthcare services.
