Attitudes towards dementia among Chinese adults aged 50 years and older: a comparative study of immigrants living in Melbourne and nonimmigrants living in Beijing.

OBJECTIVES: This study investigated attitudes towards dementia among Chinese immigrants aged 50 years and over living in Australia and compares these attitudes with those of individuals living in mainland China. It aimed to better understand what older Chinese adults think about dementia and to inform the development of tailored dementia-related services for this group of people. DESIGN: A qualitative design involving individual interviews was employed in this study. PARTICIPANTS: Forty-six participants were recruited: 21 in Melbourne and 25 in Beijing. All interviewees were born in mainland China, were community-dwelling, and did not have a dementia diagnosis. MEASUREMENTS: The tripartite model of attitudes was used to guide the semi-structured interview design and report the results. Thematic qualitative analysis was employed. RESULTS: In both groups, most participants held negative feelings, stigmatized views and negative stereotypes of dementia. However, most participants expressed a willingness to help individuals living with dementia. Regarding dementia care, nearly all participants preferred home care but thought formal care would become the mainstream form of care in the future. Fewer Melbourne participants expressed concerns regarding developing dementia, were interested in dementia, or perceived a need for dementia-related educational activities. Melbourne participants also reported more avoidant responses to dementia or individuals living with dementia. CONCLUSION: This study carefully compares attitudes towards dementia between older Chinese immigrants in Melbourne and older Chinese adults in Beijing. Similarities and differences were observed between these two groups. Dementia-related service providers should consider the sociocultural changes and migration-related barriers experienced by Chinese immigrants.

Effects of asymptomatic infection and self-initiated awareness on the coupled disease-awareness dynamics in multiplex networks

There has been growing interest in exploring the coupled epidemic-awareness dynamics within the multiplex network framework. Nevertheless, two important factors are not considered in the existing works, one is that the asymptomatic state is ignored in many epidemic dynamics, which can significantly affect the awareness and the epidemic dynamics simultaneously. The other is that the self-initiated awareness mechanism is omitted, which addresses that individuals can be altered spontaneously by the infected neighbors rather than just be informed by others. To this arm, we propose a novel coupled epidemic-awareness model in multiplex networks by incorporating these two factors and investigate their impacts on the dynamics of epidemic and awareness. Based on the microscopic Markov chain approach and Monte-Carlo simulation, our findings indicate that the asymptomatic state makes people underestimate the risk of disease, leading to insufficient diffusion of awareness and further inducing the outbreak of epidemic. On the contrary, even though the self-initiated mechanism plays a positive role on the control of epidemic, whose effect is also weakened by the existence of the asymptomatic state. More importantly, a fundamental quantity underlying the spreading dynamics–the epidemic threshold is analytically derived.

Prevalence and Risk Factors of Anxiety, Depression, and Sleep Problems Among Caregivers of People Living With Neurocognitive Disorders During the COVID-19 Pandemic.

Objectives: To estimate the prevalence of anxiety, depression, and sleep problems among caregivers of persons living with neurocognitive disorders (PLWND) during the COVID-19 pandemic in China and investigate whether the COVID-19-related experiences were associated with the presence of anxiety, depression, and sleep problems. Methods: From March 1 to 31, 2020, 160 caregivers of PLWND participated in an online cross-sectional survey on the prevalence of anxiety, depression, and sleep problems. The 7-item Generalized Anxiety Disorder Scale (GAD-7) was administered to measure anxiety symptoms, and the 2-item Patient Health Questionnaire (PHQ-2) was used to assess depressive symptoms. Questions on sleep duration and sleep quality enquired about sleep problems. Six items were used to explore the COVID-19-related experiences, including community-level infection contact and the level of exposure to media information. We computed the prevalence rate of anxiety, depressive symptoms, and sleep problems. Univariate and multivariate logistic regression analyses were performed to investigate factors associated with these mental health problems. Results: The prevalence rate of anxiety, depression, and sleep problems were 46.9%, 36.3%, and 9.4%. Approximately 55 participants (34.4%) presented with two or more mental health problems. Women had a higher risk of developing anxiety symptoms (OR, 5.284; 95% CI, 2.068-13.503; p = 0.001). Having a mental disorder (OR, 5.104; 95% CI, 1.522-17.114; p = 0.008) was associated with an increased risk of depressive symptoms. Caregivers who preferred to access positive information (OR, 0.215; 95% CI, 0.058-0.793; p = 0.021) was associated with decreased risk of sleep problems. Conclusion: Anxiety and depressive symptoms were common among caregivers of older adults with dementia or mild cognitive impairment during the COVID-19 pandemic. Being female was an independent risk factor for experiencing anxiety symptoms. Preexisting mental disorders increased the risk of depressive symptoms among caregivers, while caregivers who prefer to access positive media information decreased sleep problems.

Mental Health Multimorbidity among Caregivers of Older Adults During the COVID-19 Epidemic.

OBJECTIVE: To investigate mental health status and associated factors among caregivers of older adults during the COVID-19 epidemic in China. METHODS: From March 1 to 31, 2020, 916 caregivers of older adults participated in an online cross-sectional survey on the prevalence of anxiety, depression, and sleep problems. The seven-item Generalized Anxiety Disorder Scale (GAD-7) was administered to measure anxiety symptoms, the two-item Patient Health Questionnaire (PHQ-2) was used to assess depressive symptoms, and a self-developed questionnaire was used to assess sleep quality and duration. Six questions about COVID-19-related experiences were used to assess community-level infection contact and the level of exposure to media information. The prevalence rates of anxiety, depression and sleep problems were computed. The Wald χ2 were applied to compare the differences between subgroups. Multiple logistic regression analyses were performed to investigate factors associated with anxiety, depression, sleep problems, and multimorbidity. RESULTS: The prevalence rates of anxiety, depression, and sleep problems were 46.8%, 29.8%, and 10.8%, respectively. Approximately 263 participants (28.7%) presented with two or more mental health problems. Being female (OR, 2.254; 95% CI, 1.510-3.363), having community-level COVID-19 contact (OR, 1.856; 95% CI, 1.189-2.898), and having a mental disorder (OR, 3.610; 95% CI, 1.644-7.930) were associated with increased risk of multimorbidity among caregivers. Caregivers who preferred positive information (OR, 0.652; 95% CI, 0.472-0.899) had reduced risk of multimorbidity. CONCLUSION: Anxiety and depression were common among caregivers of older adults during the COVID-19 epidemic. Being female and having community-level COVID-19 contact were independent risk factors for experiencing multiple mental health problems. Preexisting mental disorders increased the risk of multimorbidity among caregivers, while enhanced access to positive media information decreased the risk of multimorbidity.
