Awareness, knowledge, perceptions, and attitudes towards genetic testing for cancer risk among ethnic minority groups: a systematic review.

ABSTRACT:

Background

Genetic testing for risk of hereditary cancer can help patients to make important decisions about prevention or early detection. US and UK studies show that people from ethnic minority groups are less likely to receive genetic testing. It is important to understand various groups' awareness of genetic testing and its acceptability to avoid further disparities in health care. This review aims to identify and detail awareness, knowledge, perceptions, and attitudes towards genetic counselling/testing for cancer risk prediction in ethnic minority groups.

Methods

A search was carried out in PsycInfo, CINAHL, Embase and MEDLINE. Search terms referred to ethnicity, genetic testing/counselling, cancer, awareness, knowledge, attitudes, and perceptions. Quantitative and qualitative studies, written in English, and published between 2000 and 2015, were included.

Results

Forty-one studies were selected for review: 39 from the US, and two from Australia. Results revealed low awareness and knowledge of genetic counselling/testing for cancer susceptibility amongst ethnic minority groups including African Americans, Asian Americans, and Hispanics. Attitudes towards genetic testing were generally positive; perceived benefits included positive implications for personal health and being able to inform family. However, negative attitudes were also evident, particularly the anticipated emotional impact of test results, and concerns about confidentiality, stigma, and discrimination. Chinese Australian groups were less studied, but of interest was a finding from qualitative research indicating that different views of who close family members are could impact on reported family history of cancer, which could in turn impact a risk assessment.

Conclusion

Interventions are needed to increase awareness and knowledge of genetic testing for cancer risk and to reduce the perceived stigma and taboo surrounding the topic of cancer in ethnic minority groups. More detailed research is needed in countries other than the US and across a broader spectrum of ethnic minority groups to develop effective culturally sensitive approaches for cancer prevention.

Project description:BackgroundThe twenty first century can be called the genomic era referring to the rapid development of genetics, and the beginning of genomic medicine. An initial step towards genomic medicine is to evaluate the knowledge and attitude towards genetic testing among different populations. The aims of this study were to assess the genetic knowledge and attitude towards genetic testing among the Jordanian population and patients with immune diseases. In addition, we evaluated the association between knowledge, attitude and several demographic factors of the population.MethodsThis study was performed using an online questionnaire that was distributed to respondents from different regions of Jordan.ResultsA total of 1149 participants were recruited from the Jordanian population. Overall factual genetic knowledge of the participants was good (65.4%), with education level, working or studying in a health-related field and household average monthly income being significant predictors of factual knowledge scores (P = 0.03, P < 0.001 and P < 0.001, respectively). However, factual knowledge results revealed that scores of questions related to diseases were significantly higher than scores of gene-related scientific facts (P < 0.01). Participants of our study reported to have low perceived knowledge on medical uses (39.5%) and social consequences (23.9%) of genetic testing. Regarding the participants' attitudes, favorable attitudes towards genetic testing were prevailing (91.5%). Favorable attitudes were more prominent among higher educated participants, and participants with higher scores of factual knowledge.ConclusionDespite the fact that our Jordanian-based study revealed a good level of genetic knowledge as well as a favorable attitude towards genetic testing, we realized an imbalance of knowledge between gene-related scientific facts and disease-related concepts as well as between factual and perceived genetic knowledge, which indicates the necessity of increasing the awareness about genetic testing in order to ensure that individuals can take informed decisions that help in the employment of personalized medicine.

Project description:BackgroundCertain racial/ethnic minority groups have a higher risk of developing dementia, yet studies have demonstrated that they often have limited knowledge and understanding of this disease. An increasing number of educational and advocacy programs have been developed to promote dementia knowledge. We aimed at assessing current evidence and quality regarding educational interventions for promoting dementia knowledge.MethodsWe searched for intervention studies published in English that focused on educational interventions for promoting dementia knowledge among racial/ethnic minority groups. We identified 25 relevant studies through PubMed, PsycINFO, CINAHL, and Scopus, using tailored search terms. We screened titles and abstracts, reviewed full texts, synthesized relevant evidence, and evaluated the studies' quality based on the Mixed Methods Appraisal Tool. Relevant intervention studies took place in communities, hospitals or clinics, and schools, and online.ResultsMost studies were conducted in the United States (n = 21), followed by the UK (n = 3). Over half of the studies included Asian/Pacific Islander groups (n = 14), followed by Black groups (n = 12) and Hispanic groups (n = 11). The intervention delivery mode varied across studies-from workshops hosted in a faith community to talk shows on YouTube. Target populations included middle-aged and older adults, caregivers and family members, health students and professionals, and elementary school students. Common content included symptoms and signs of dementia, protective and risk factors, and local resources. The assessment of study outcomes varied across studies. Improvement in dementia knowledge and attitudes towards dementia was reported in many studies. Among the included studies, intervention satisfaction was high. The overall quality of the interventions was low.ConclusionFormally evaluated educational interventions promoting dementia knowledge are at an early stage. Existing published interventions showed adequate acceptability and promise in promoting better understanding and awareness of dementia in minority groups. More well-designed randomized controlled trials are needed.

Project description:BackgroundOutbreaks of dengue fever are often found among Dai ethnical communities along China-Myanmar border. The objective of this study was: 1) to investigate residents' health perceptions, knowledge and control willingness to participate in dengue control and 2) to identify factors associated with control willingness among the Dai ethnic community.MethodsThis is a mixed method study of a cross-sectional design, in which qualitative in-depth interviews and quantitative household questionnaire surveys are included.ResultsQuestionnaire was administered to 261 household heads, and in-depth interview was conducted with 18 key informants. Of them, many participants (70%, 182/259) and 12 key informants (66.7%) from the two rural communities believed that the Lord Buddha would protect the good people. Majority of the participants (81.4%, 206/253) knew that fever was one of dengue fever symptoms and most of them (82.2%, 213/259) indicated that mosquitoes could transmit dengue fever. However, only one third of the participants (30.1%, 78/259) indicated the perceived susceptibility of dengue fever, and only a half of them (50.2%, 130/259) indicated the perceived severity of dengue fever. Multivariate logistic analysis (MLA) indicated that the participants with family wealth index (FWI) 4-5 (OR: 22.9728; 95%CI: 2.4257-217.5688, p = 0.0063) were more likely to turn containers upside down (TCUD) compared to those with FWI 1-3; and the participants in the urban community (OR: 0.0239; 95%CI: 0.0019-0.3032, p = 0.004) were less likely to TCUD compared to those in the two rural communities. Around one third of the participants (36.8%, 96/239) reported that they were willing to seek treatment first for dengue fever from public health facilities. The MLA identified that the participants with the perceived severity of dengue fever (OR: 5.0564; 95%CI: 2.0672-12.3683, p = 0.0004), and with beliefs of sound hygiene helpful to people's health (OR: 11.5671; 95%CI: 2.0505-65.2502, p = 0.0055) were more likely to seek treatment first for dengue fever from the public health facilities.ConclusionThe study finds that most of Dai people have sound knowledge. However, health educational interventions should target to promote the perceived susceptibility and the perceived severity of dengue fever among Dai people.
