Background: The aim of this cross-sectional study was to assess the dementia literacy of community-dwelling adults in four cities (Hong Kong, Guangzhou, Macau, and Zhuhai) of the Greater Bay Area of China, and to determine their mass media preferences for receiving dementia information. Methods: The survey was completed by 787 community-dwelling adults. Dementia literacy was indirectly measured using two validated scales—the 30-item Alzheimer’s Disease Knowledge Scale and the 20-item Dementia Attitude Scale (DAS). Participants were also asked to indicate whether they wanted to receive dementia information via digital or traditional media. Chi-square tests, logistic regressions, and MANOVA analyses were conducted. Results: Unemployed or retired people had poor attitudes towards dementia and lower levels of knowledge about dementia. Single, cohabiting, or divorced people in Hong Kong and Macau had lower DAS scores than married people. Young people and those with a secondary education preferred to get their dementia information from social media. People with a tertiary education and employed people enjoyed searching government or hospital websites for information. Middle-aged, unemployed, or retired people tended to learn about dementia from television or radio. Conclusion: It is worth educating the public about dementia and developing strategies consistent with their preferences for types of mass media.

Background: This study aimed to assess the dementia literacy (DL) level of community-dwelling adults in the four cities (Hong Kong, Guangzhou, Macau and Zhuhai) of the Greater Bay Area of China and to determine the preferred mass media for receiving dementia information. Methods: A multi-city cross-sectional study with 788 community-dwelling adults completed the survey. Dementia literacy was indirectly measured by two validated scales, 30-item Alzhiemer’s Disease Knowledge Scale (ADKS) and 20-item Dementia Attitudes Scale (DAS). When the ADKS total score was <15 and DAS total score was <70, it was considered as ‘inadequate dementia literacy’. Participants were also asked to indicate whether they would like to receive dementia information via digital media or traditional media. Chi-square tests and logistic regressions were undertaken. Results: About one-third of the participants had inadequate dementia literacy. Those with young age or secondary education preferred to get dementia information from social media. But people living in public housing would like to get information from government or hospital websites. Middle-aged participants inclined to learn dementia from television or radio. Conclusion: It is worthy to conduct territory-wide public education in dementia and develop strategies according to their preferences in the types of mass media.

Background: As population ageing and dementia incidence continue to increase worldwide, health systems are urged to empower the public to address factors related to dementia. This study aims to assess Macau citizens’ knowledge of dementia, attitudes towards persons with dementia, and help-seeking behaviours and intention toward dementia.Methods: This is a mixed-methods study with both quantitative (cross-sectional survey) and qualitative components (focus group interviews). The Alzheimer’s Disease Knowledge Scale (ADKS) and Dementia Attitude Scale (DAS) were utilized in the quantitative data collection, whereas focus group interviews were employed to gather context-specific understanding of dementia in the local setting. Descriptive statistics and Chi-square tests were used to analyze quantitative data, while content analysis was used for qualitative data.Results: The overall level of knowledge on dementia was low (ADKS mean total score = 17.38, SD = 3.31), with the least amount of knowledge in the caregiving domain. Meanwhile, attitudes toward persons with dementia was generally positive (mean [SD] = 89.07 [11.99]). Many of the focus group participants were also uncertain regarding the availability of dementia services in the region. The general public was interested to obtain dementia information through social media.Conclusions: Efforts should be made to build up dementia literacy in Macau, especially in terms of caregiving. Information about dementia could be disseminated in social media and by healthcare professionals.
