Experiences and attitudes of residents regarding a community-based genome cohort study in Japan: a population-based, cross-sectional study

Participant mothers' attitudes toward genetic analysis in a birth cohort study

To conduct a long-term birth cohort study that includes genetic analysis, it is crucial to understand the attitudes of participants to genetic analysis and then take appropriate approaches for addressing their ambiguous and negative attitudes. This study aimed to explore participants’ attitudes toward genetic analysis and associated background factors among mothers who were enrolled in a large Japanese birth cohort. A questionnaire was sent to participants’ households, and the responses of 1762 mothers (34.0%) were used for the study. The majority of mothers recognized genetic analysis for themselves and their children and sharing of genetic data as beneficial. A low knowledge level of genomic terminology was associated with ambiguous attitudes toward genetic analysis and data sharing. Education level was positively associated with the recognition of the benefits of genetic analysis. Concern about handling genetic information was associated with the unacceptability of data sharing. Trust was associated with the approval of genetic analysis. Most mothers preferred that genetic analysis results be returned. These findings suggest the need for multiple efforts to maximize participants’ acceptance of genetic analysis, such as utilizing an educational approach to encourage familiarity with genetics/genomics, optimizing explanations for different educational levels, and explicitly disclosing the handling policy for genetic information.

Citizens' Attitudes, Knowledge, and Educational Needs in the Field of Omics Sciences: A Systematic Literature Review

Background: The huge development of omics sciences is changing the classical medical approach and making new technologies available. In this context, education of citizens is essential to allow appropriate decisions about their own health. Hence, we aimed to summarize existing literature regarding citizens' knowledge, attitudes, and educational needs on omics sciences. Methods: We performed a systematic literature review (SLR) using Pubmed, ISI Web of Science, and Embase databases. The eligibility criteria for inclusion in this review required that the studies investigated knowledge, attitudes, or educational needs regarding omics sciences among the general population. Results: We included 54 studies, published between 2006 and 2020. Most of the included studies (72%) investigated citizens' knowledge, half of them (56%) attitudes, and 20% educational needs in the field of omics sciences, while 52% investigated attitudes and perceptions about genetic and/or omics tests. Most studies (64%) reported a limited knowledge level among citizens, even though most (59%) reported participants understood the benefits of the use of omics sciences into medicine. As for omics tests, a controversial opinion toward their use into practice was reported among citizens. Most of the studies (82%) investigating citizens' educational needs highlighted a clear gap to be filled. Conclusions: Our SLR summarizes current knowledge on citizens' literacy, attitudes, and educational needs on omics science, underlining the need for strengthening public engagement on this topic. Further research is needed, however, to identify appropriate methods and models to achieve such an improvement.

The survey of public perception and general knowledge of genomic research and medicine in Japan conducted by the Japan Agency for Medical Research and Development

Japan has been proactively promoting genomic medicine initiatives as national policy. With rapid pace developments in genomic medicine, an increasing number of patients and their families will be able to access genomic information. In such circumstances, a consideration of public interests and an assessment of the general knowledge about genomic research and genomic medicine are becoming imperative. This study aims to elucidate public attitude to the handling of genetic information during research and general medicine. The results of the questionnaire survey of 3000 people have revealed the following points: (1) older participants were likely to have better knowledge of genetic information than younger ones; (2) people with better understanding of genetic information tended to care more strongly about technical issues; (3) respondents with higher literacy regarding genetic issues favored stricter rules for handling of genetic information compared to handling of ordinary medical data; and (4) research community and funding agencies should preserve and develop public trust in genomic research and medicine. These results suggest the importance of education for younger people, the need of different types of explanation and transparency aimed at individuals with different levels of knowledge about the genome, and indicate the adequacy of the current governmental guidelines.
