Using Qualitative Research to Explore Maternal and Child Health Experiences Among Brazilian Immigrants in the U.S.: A Systematic Review and Meta-Synthesis

Background: Maternal and child health (MCH) is a critical public health issue affecting individuals, families, and communities worldwide. Immigrant populations, including Brazilian mothers and children in the United States (U.S.), face unique challenges, such as language barriers, limited healthcare access, and socioeconomic disparities that exacerbate health risks. Despite their growing numbers, Brazilian immigrants in the U.S. are an understudied group in MCH research. Objective: This systematic review and qualitative meta-synthesis aims to identify, appraise, and synthesize qualitative and mixed-methods research focused on the MCH experiences of Brazilian immigrants in the U.S. Methods: This review will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines and is registered with PROSPERO, an international prospective registry of systematic reviews. Qualitative and mixed-methods research published between 2004 and 2024 that explicitly report qualitative methodology, analysis, and findings related to MCH experiences among Brazilians in the U.S. will be eligible to be included. Studies will be identified through a comprehensive search of seven databases (CINAHL, MEDLINE, PubMed, PsycINFO, Web of Science, Scopus, SocINDEX), and selected according to predefined inclusion/exclusion criteria. Only studies available in English, Portuguese, or Spanish and reporting original qualitative data will be included. Data extraction will be conducted using the Joanna Briggs Institute (JBI) Data Extraction Tool for Qualitative Research. Findings will be synthesized using the JBI meta-aggregation approach in MAXQDA software and evaluated for confidence using the JBI Confidence in Qualitative Research (ConQual) tool. Conclusions: By synthesizing qualitative findings, this review aims to inform the development of culturally responsive healthcare policies, community-based interventions, and future research tailored to the unique needs and experiences of Brazilian immigrant mothers and children in the U.S.
