Where culture meets genetics: Exploring Latina immigrants' lay beliefs of disease inheritance. Soc Sci Med 2019; 271:112179. [PMID: 30853189 DOI: 10.1016/j.socscimed.2019.02.030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Revised: 02/10/2019] [Accepted: 02/19/2019] [Indexed: 01/06/2023]
Abstract
As medical genetic services become a standard part of healthcare, it will become increasingly important to understand how individuals interpret and use genetic information. Exploring lay beliefs of disease inheritance that differ along cultural lines is one research strategy. The purpose of this study was to describe conceptualizations of disease inheritance held by members of the Latina immigrant population in the United States. Semi-structured interviews were employed to gather qualitative, exploratory data from 20 Latina immigrant women. All interviews were conducted in Spanish, and thematic analysis was used to analyze interview transcripts. Demographic and acculturation data were also collected and analyzed. The final sample was diverse in age, time lived in the United States, country of birth, and education level. From participant interviews, the authors identified one dominant model of disease inheritance to which most participants ascribed as well as two non-dominant models. The main model was characterized by a focus on the ability to modify an underlying disease risk, especially in the case of hereditary predisposition to common complex disease. Of the non-dominant models, one focused on genetic disease as extraordinary and less modifiable while the other placed less emphasis on the role of genes in health and greater emphasis on non-genetic factors. Across these models, participants expressed their uncertainty about their understanding of genetics. Many of the themes that arose from the interviews, including uncertainty in their own understanding of genetics, were similar to those seen in studies among other populations. Importantly, participants in this study demonstrated a lack of genetic fatalism, which may allay fears that explaining the role of genetics in common health conditions will reduce uptake of positive health behaviors. These findings have practice implications for healthcare providers communicating genetic information to Latina immigrants.

Ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries: a systematic review. Genet Med 2018; 23:2270-2280. [PMID: 30072741 DOI: 10.1038/s41436-018-0090-9] [Citation(s) in RCA: 39] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Accepted: 06/04/2018] [Indexed: 12/17/2022] Open
Abstract
PURPOSE We performed a systematic review of the ethical, social, and cultural issues associated with delivery of genetic services in low- and middle-income countries (LMICs). METHODS We searched 11 databases for studies addressing ethical, social, and/or cultural issues associated with clinical genetic testing and/or counselling performed in LMICs. Narrative synthesis was employed to analyze findings, and resultant themes were mapped onto the social ecological model (PROSPERO #CRD42016042894). RESULTS After reviewing 13,308 articles, 192 met inclusion criteria. Nine themes emerged: (1) genetic counseling has a tendency of being directive, (2) genetic services have psychosocial consequences that require improved support, (3) medical genetics training is inadequate, (4) genetic services are difficult to access, (5) social determinants affect uptake and understanding of genetic services, (6) social stigma is often associated with genetic disease, (7) family values are at risk of disruption by genetic services, (8) religious principles pose barriers to acceptability and utilization of genetic services, and (9) cultural beliefs and practices influence uptake of information and understanding of genetic disease. CONCLUSION We identified a number of complex and interrelated ethical, cultural, and social issues with implications implications for further development of genetic services in LMICs.
