“…Nei's genetic distances between Santal population and 28 other published populations.The analysis showed that the Santals lie genetically close to the Munda population belonging to a cluster which includes Kora, Lodha, Karmali, Maheli, Gond, Bhil, Tamil, and Mahadev Koli from different states of India (Fig1). Neighbor-joining tree bases on Nei's DA distance among Santals and 28 other geographically close populations.A previous study conducted from this laboratory based on Ychromosomal STRs also revealed a close genetic relationship between Santal population from Dinajpur, Bangladesh and Munda population from Jharkhand, India25 . The genetic affinity of Santal population with these populations may be due to a possible sharing of paternal lineage and genes during migration.In conclusion, this study demonstrated that the 15 autosomal STR loci reported here offer a highly discriminating system for use in parentage testing and forensic identification of individuals in this population.…”

Fifteen autosomal STR markers, namely D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA were typed using AmpFlSTR® Identifiler® Plus PCR amplification systems in 132 unrelated Santal individuals of Bangladesh. Forensic efficiency parameters like, matching probability (MP), power of discrimination (PD), polymorphism information content (PIC), power of exclusion (PE), typical paternity index (TPI), observed heterozygosity (Hobs), and expected heterozygosity (Hexp) were calculated for all the loci. No deviations from Hardy-Weinberg equilibrium were detected for the loci after Bonferroni correction. The combined matching probability (MP), combined power of discrimination (PD) and combined power of exclusion (PE) for the 15 tested STR markers were 8.38 x 10-17, 0.999999998 and 0.0.999993866, respectively. A comparison of the locus wise allele frequencies of autosomal STR data of the Santal population with the published geographically close population data based on Nei’s genetic distance revealed that the Santal population is closely related to Munda population from Jharkhand, India.

“…Thus, there is a critical need for further research considering the unique family structures and socio-cultural contexts of various underprivileged indigenous women groups residing in Bangladesh's lowlands. To fill this research gap, the current study focused on the case of the Garo indigenous women lived in the lowlands of Mymensingh, Netrakona, Gazipur, Sherpur, and Tangail [ 46 , 47 ].…”

“…Compared to other indigenous groups of this country, the Garo belongs to a matrilineal-matrilocal society [ 47 ] and represents one of the few close-knit indigenous communities in the world [ 48 ]. Being significantly impacted by neighborhood culture and practices, the Garo indigenous population maintains different sociocultural traditions different from other indigenous communities and mainstream Bangladeshis [ 49 ].…”

Background The indigenous Garo is a close-knit matrilineal-matrilocal community. This community's expectant mothers receive less antepartum biomedical care, making them prone to maternal mortality. This study developed a conceptual framework to explore how the external environment, personal predispositions, enabling components and perceived antepartum care needs influence and generate a gap in antepartum biomedical care uptake. Methods The author used qualitative data from the study area. The data were collected through conducting 24 semi-structured interviews with purposively selected Garo women. After transcribing the data, the author generated the themes, grouped them into two broader domains, and analyzed them using the grounded theory approach. Results The emergent themes suggest adding the external environment (i.e., healthcare facilities' availability and services and culturally relevant healthcare services) to Anderson's behavioral model to understand indigenous women's antepartum care uptake disparity. Antepartum care uptake disparities arise when Andersen's behavioral model's other three drivers-personal predisposition, enabling components, and needs components-interact with the external environment. The interplay between enabling resources and the external environment is the conduit by which their predispositions and perceived needs are shaped and, thus, generate a disparity in antepartum care uptake. The data demonstrate that enabling resources include gendered power dynamics in families, home composition and income, men's spousal role, community practices of maternal health, and mother groups' and husbands' knowledge. Birth order, past treatment, late pregnancy, and healthcare knowledge are predispositions. According to data, social support, home-based care, mental health well-being, cultural norms and rituals, doctors' friendliness, affordable care, and transportation costs are perceived needs. Conclusions Garo family members (mothers/in-laws and male husbands) should be included in health intervention initiatives to address the problem with effective health education, highlighting the advantages of biomedical antepartum care. Health policymakers should ensure the availability of nearby and culturally appropriate pregnancy care services.

“…This study examines how racism impacts Garo Indigenous women’s experience of accessing biomedical maternal healthcare in Bangladesh. The Garo community is one of the largest Indigenous communities in Bangladesh [ 46 ], and one of the few close-knit communities worldwide [ 47 ]. They follow a unique ‘matrilineal-matrilocal’ family structure [ 47 ].…”

Racism and access to maternal health care among garo indigenous women in Bangladesh: A qualitative descriptive study

Racism as social determinant of health significantly affects Indigenous women’s maternal healthcare access. This study uses Jones’ ‘Three Levels of Racism’ theory and an intersectional lens to explore how racism shapes the experience of maternal health care access among Garo Indigenous women in Bangladesh. Semi-structured interviews were conducted with 24 women of diverse backgrounds and pregnancy statuses using snowball sampling. Thematic analysis, incorporating inductive and deductive approaches, was employed for data analysis. The findings reveal a significant deviation from Jones’ theory regarding the level of internalized racism within the specific context of Garo Indigenous women’s experiences. Jones’ theory usually focuses on how racism is internalized due to institutional and personally-mediated factors. On the contrary, this study uncovers a unique theme: ‘women agency.’ This theme emerges as a robust response among the Garo Indigenous women to their encounters with institutional and personally-mediated racism, highlighting their cultural resistance and resilience. The findings suggest that the complex relationship between these two forms of racism contributes to the strengthening of agency among Garo Indigenous women. Their agency stems from avoiding hospitals that disrespect their culture, manifesting their cultural resistance practice against the encountered racism at the institutional and relational levels. To increase biomedical healthcare access among Garo Indigenous women, it is recommended to address racism through intercultural competency training with the ‘cultural safety’ ‘cultural humility’ approach. This approach would foster inclusivity and empowerment, recognizing the agency of Garo women in healthcare decisions. Additionally, it would facilitate constructive dialogues between clinicians and Garo Indigenous women, acknowledging the shared experiences of racism within the latter group.
