Immigrant populations, particularly undocumented immigrants, are often considered ‘hidden’ or ‘hard to reach’ in research. This invisibilisation—under-representation or exclusion in data collection—leads to data inequities and biased findings that fail to capture their unique experiences. Starfish sampling mitigates selection bias and improves access to invisibilised populations by recruiting ‘seed’ participants at randomly selected times and locations and leveraging their social networks to recruit the next wave of participants. In this protocol paper, we outline the sampling strategy for the BRAVE (Building community, Raising All immigrant Voices for health Equity) study, a multi-site, cross-sectional survey examining the relationship between immigration history and sexual and reproductive health (SRH) service utilisation among Asian immigrant women in the USA. This protocol is an adaptation of novel starfish sampling in combination with various data tools and a community-based participatory research approach.

Using data from the American Community Survey and insights from community partners, we will conduct community mapping across four study sites (Atlanta, Houston, Los Angeles County and New York City). We will select census tracts that reflect the primary ethnic groups of interest and diverse socioeconomic backgrounds. From these selected census tracts, we will construct a venue universe by identifying key activity areas for Asian immigrant women through data scraping from online sources. We will then randomly select venue-date-time combinations and deliberately choose various community engagement events for recruitment. Culturally competent field officers who are fluent in Asian languages will recruit participants at these events. Participants can refer up to three peers from their social networks to take part in the survey. Results will be presented as descriptive statistics and logistic regression models to test the association between immigration history and SRH service utilisation.

The overarching BRAVE study protocol was approved by the University of California Los Angeles Institutional Review Board (IRB) (IRB-22–0493-AM-016). The results will be disseminated through academic journal publications and relevant data will be shared with our community partners.

The COVID-19 pandemic disrupted maternal healthcare access globally, leading many women to give birth outside of healthcare facilities, often assisted by traditional birth attendants (TBAs). This study explored the experiences of Kenyan women who gave birth outside of healthcare facilities during the COVID-19 pandemic based on the Person-Centered Maternity Care (PCMC) framework.

This study used data from descriptive qualitative indepth interviews with Kenyan women who gave birth outside of healthcare facilities between March and November 2020. Participants lived within the catchment areas of six health facilities in Kiambu and Nairobi counties and were recruited by community leaders and community health workers. Interviews were conducted in 2020 via phone and inductively coded and analysed by a team of researchers.

A total of 28 Kenyan women who gave birth outside of healthcare facilities between March and November 2020 completed indepth interviews.

In this sample, approximately one-third of women were assisted by TBAs, while the majority were supported by friends and family members. Women generally described salient aspects of their care pertaining to the PCMC domain of supportive care. During labour, birth and the immediate postpartum, women received emotional support, basic medical assistance and instrumental support such as preparing food and baths. However, women also described concerns about giving birth outside of healthcare facilities, including poor hygiene and lack of privacy in birthing spaces as well as instances of verbal and physical harassment by TBAs. Overall, women worried about potential complications during birth, and many women delayed seeking postpartum and postnatal care.

Women who were unable to access healthcare facilities during the COVID-19 pandemic relied on TBAs and/or friends and family for support during labour and birth. These women faced gaps in PCMC, specifically related to supportive care. Given that birthing outside of healthcare facilities remains common globally, particularly during emergencies such as pandemics, TBAs should be supported to provide more person-centred care to women giving birth outside of healthcare facilities.
