Public Discourse and Sentiment Toward Dementia on Chinese Social Media: Machine Learning Analysis of Weibo Posts

Kong, D., Chen, A., Zhang, J., Xiang, X., Lou, W. Q., Kwok, T., & Wu, B. (2022). Journal of Medical Internet Research, 24(9). 10.2196/39805
Abstract
Abstract
Background: Dementia is a global public health priority due to rapid growth of the aging population. As China has the world’s largest population with dementia, this debilitating disease has created tremendous challenges for older adults, family caregivers, and health care systems on the mainland nationwide. However, public awareness and knowledge of the disease remain limited in Chinese society. Objective: This study examines online public discourse and sentiment toward dementia among the Chinese public on a leading Chinese social media platform Weibo. Specifically, this study aims to (1) assess and examine public discourse and sentiment toward dementia among the Chinese public, (2) determine the extent to which dementia-related discourse and sentiment vary among different user groups (ie, government, journalists/news media, scientists/experts, and the general public), and (3) characterize temporal trends in public discourse and sentiment toward dementia among different user groups in China over the past decade. Methods: In total, 983,039 original dementia-related posts published by 347,599 unique users between 2010 and 2021, together with their user information, were analyzed. Machine learning analytical techniques, including topic modeling, sentiment analysis, and semantic network analyses, were used to identify salient themes/topics and their variations across different user groups (ie, government, journalists/news media, scientists/experts, and the general public). Results: Topic modeling results revealed that symptoms, prevention, and social support are the most prevalent dementia-related themes on Weibo. Posts about dementia policy/advocacy have been increasing in volume since 2018. Raising awareness is the least discussed topic over time. Sentiment analysis indicated that Weibo users generally attach negative attitudes/emotions to dementia, with the general public holding a more negative attitude than other user groups. Conclusions: Overall, dementia has received greater public attention on social media since 2018. In particular, discussions related to dementia advocacy and policy are gaining momentum in China. However, disparaging language is still used to describe dementia in China; therefore, a nationwide initiative is needed to alter the public discourse on dementia. The results contribute to previous research by providing a macrolevel understanding of the Chinese public’s discourse and attitudes toward dementia, which is essential for building national education and policy initiatives to create a dementia-friendly society. Our findings indicate that dementia is associated with negative sentiments, and symptoms and prevention dominate public discourse.

Public trust in the long-term care insurance pilot program in China: An analysis of mediating effects

Peng, R., Zhang, W., Deng, X., & Wu, B. (2022). Frontiers in Public Health, 10. 10.3389/fpubh.2022.928745
Abstract
Abstract
Objective: This study aimed to evaluate the implementation of the long-term care insurance (LTCI) pilot program in China through an examination of public trust in the system and its associated factors of insurance awareness and satisfaction with the LTCI policy. Method: An online survey was used to collect data from 786 participants in the city of Guangzhou, one of the pilot sites of the LTCI. Ordinal logistic regression models were used to investigate the related factors of public trust in the LTCI. Structural equation modeling (SEM) was conducted to test the mediating effect of satisfaction with LTCI policy on the relationship between insurance awareness and public trust. Results: More than 60% of participants gave a positive evaluation of the LTCI pilot program. More than 70% of the participants recognized the important role of the program. Both an understanding of insurance and satisfaction with LTCI policies were associated with public trust. The proportion of the indirect effect with regard to the total effect of satisfaction on trust was 70.133%, greater than the direct effect of 29.867%. Conclusions: Our findings supported the hypothesis that satisfaction with the LTCI policy plays a mediating role between insurance awareness and public trust. Optimalization of the LTCI policy was recommended to improve public trust in the LTCI program.

A qualitative analysis of communication workflows between adult day service centers and primary care providers

Zhong, J., Boafo, J., Brody, A. A., Wu, B., & Sadarangani, A. T. (2022). Journal of the American Medical Informatics Association, 29(5), 882-890. 10.1093/jamia/ocab284
Abstract
Abstract
Objectives: Our study documented communication workflows across adult day care centers (ADCs) and primary care providers (PCPs) around complex needs of persons living with dementia (PLWD). We also identified barriers and facilitators to productive communication in clinical decision support and clinical information systems. Materials and Methods: We conducted 6 focus groups with ADC staff (N=33) and individual semistructured interviews with PCPs (N=22) in California. The eHealth Enhanced Chronic Care Model was used to frame the directed qualitative content analysis. Results: Our results captured cumbersome and ineffective workflows currently used to exchange information across PCPs and ADCs. Stakeholders characterized current communication as (1) infrequent, (2) delayed, (3) incomplete, (4) unreliable, (5) irrelevant, and (6) generic. Conversely, communication that was bidirectional, relevant, succinct, and interdisciplinary was needed to elevate the standard of care for PLWD. Discussion and Conclusion: ADCs possess a wealth of information that can support clinical decision-making across community-based providers involved in the care of PLWD, especially PCPs. However, effective information exchange is mired by complicated workflows that rely on antiquated technologies (eg, facsimile) and standard templates. Current information exchange largely focuses on satisfying regulatory guidelines rather than supporting clinical decision-making. Integrating community-based services into the health care continuum is a necessary step in elevating the standard of care for PLWD. In the absence of interoperable electronic health records, which may not be financially viable for ADCs, other options, such as mobile health, should be explored to facilitate productive information exchange of personalized relevant information.

Quality of Life and Its Influencing Factors Among Centenarians in Nanjing, China: A Cross-Sectional Study

Xu, X., Zhao, Y., Xia, S., Cui, P., Tang, W., Hu, X., & Wu, B. (2022). Social Indicators Research, 160(2), 735-755. 10.1007/s11205-020-02399-4
Abstract
Abstract
As centenarians are the most vulnerable social group among older adults, their quality of life (QoL) is of great significance for the realization of healthy aging and a harmonious society. The purpose of this cross-sectional study was to propose a multidimensional analysis of centenarians’ QoL to examine the factors associated with QoL. In the study, a factor analysis method, including exploratory factor analysis and confirmatory factor analysis, was used to uncover the latent structure of QoL and to monitor the dimension, reliability, and validity of the measurement scale. Structural equation model was performed to test the proposed hypotheses. Based on Lawton’s “the good life” theoretical framework, we constructed our QoL model with four dimensions: physical health, mental health, family and social relationships, and socioeconomic status. After the factor analysis, three main hypotheses were presented. The results of the final QoL model revealed that two hypotheses of the relationships between QoL and “physical health” and “socioeconomic status” were supported. This paper suggests that interventions related to improving functional health and living standard could enhance the QoL for centenarians.

Racial/Ethnic Disparities in Getting COVID-19 Vaccine: Do Age, Gender, and Education Matter?

Zhang, W., Wu, Y. Y., & Wu, B. (2022). Health Equity, 6(1), 500-507. 10.1089/heq.2022.0025
Abstract
Abstract
Objectives: COVID-19 disproportionately affects racial/ethnic minorities and vaccine can help mitigate infection and transition, decrease rate of hospitalization, lower mortality rate, and control the pandemic. This study aims to examine disparities in COVID-19 vaccination rate by age among Whites, Hispanics, Blacks, and Asian Americans, and the modification effects by gender and education. Methods: We used seven waves of biweekly surveys from the Household Pulse Survey collected between July 21, 2021, and October 11, 2021. Results: Asians reported the highest, Blacks reported the lowest vaccination rate, and gender differences were minimal. Increasing age was associated with higher vaccination rate except for the oldest age group. The decline was from 84.4% (70-79 years) to 41.1% (80-88 years: 41.1%) among Hispanics and 92.8% to 69.6% among Asians. Educational effect was the most salient among younger adults with the largest gaps observed in Blacks. Among 18-29-year Black participants, the vaccination rates were 31.1% (confidence interval [95% CI]: 25.7-37.1) for high school or lower, 58.9% (95% CI: 54.2-63.5) for some college or associate degree, and 74.2% (95% CI: 69.4-78.5) for bachelor or higher degrees, leaving a 43.1% gap between the lowest and the highest education levels. The gaps in this age group were 33.7% among Whites, 32.1% among Hispanics, and 20.5% among Asian Americans. Conclusion: Our study advances the existing literature on COVID-19 vaccination by providing empirical evidence on the dynamic race/ethnic-age-education differences across racial/ethnic groups. The findings from our study provide scientific foundation for the development of more strategies to improve vaccination rate for the minority populations.

Social capital, perceived neighborhood environment, and depressive symptoms among older adults in rural China: The role of self-rated health

Lu, N., Wu, B., Pei, Y., & Peng, C. (2022). International Psychogeriatrics, 34(8), 691-701. 10.1017/S1041610221000958
Abstract
Abstract
Objectives: This study examined the relationships between social capital, perceived neighborhood environment, and depressive symptoms among older adults living in rural China, and the moderating effect of self-rated health (SRH) in these relationships. Participants: A quota sampling method was applied to recruit 447 participants aged 60 years and older in rural communities in Jilin province, China in 2019. Measurements: Depressive symptoms were measured by the Center for Epidemiologic Studies Depression Scale. Structural equation modeling was used to build latent constructs of social capital and test the proposed model. Multiple group analysis was used to test the moderation effects. Results: Cognitive social capital and structural social capital were both associated with depressive symptoms controlling for participants' demographics, socioeconomic status, and health status. After adding perceived environment variables in the model, the relationship between cognitive social capital and depressive symptoms became nonsignificant, while structural social capital remained became a significant factor (β = -.168, p <.01). Satisfaction with health care was significantly associated with depressive symptoms among those with poor SRH (β = -.272, p <.01), whereas satisfaction with security and transportation were strongly associated with depressive symptoms among those with good SRH (security: β = -.148, p <.01; transportation: β = -.174, p <.01). Conclusions: Study findings highlighted the importance of social capital and neighborhood environment as potential protective factors of depressive symptoms in later life. Policy and intervention implications were also discussed.

Social isolation and psychological well-being among older Chinese Americans: Does resilience mediate the association?

Qi, X., Zhang, W., Wang, K., Pei, Y., & Wu, B. (2022). International Journal of Geriatric Psychiatry, 37(8). 10.1002/gps.5791
Abstract
Abstract
Objectives: Social isolation imposes risks to an individual's psychological well-being. However, few studies have examined the role of resilience on these associations among older Chinese Americans, the fastest-growing aging population across all racial/ethnic groups in the United States. We aim to examine the associations of social isolation with indicators of psychological well-being and the mediating role of resilience in these associations. Methods: Data were derived from 398 Chinese older adults aged over 55 residing in Honolulu, Hawaii, in 2018. Psychological well-being was measured by psychological distress, life satisfaction, and happiness. Multivariate linear regressions and ordered logistic regressions were conducted. Results: Social isolation was positively associated with psychological distress and negatively associated with life satisfaction and happiness (all p < 0.05). By contrast, resilience was associated with lower levels of psychological distress and higher levels of life satisfaction and happiness (all p < 0.05). Moreover, the findings supported our hypothesis that resilience mediated the association between social isolation and psychological well-being. With regard to social isolation, resilience contributed to 32.0% of its association with distress, 24.9% of the association with life satisfaction, and 16.3% of the association with happiness. Conclusion: Our findings revealed a significant association between social isolation and psychological well-being and the mediating role of resilience in the association of older Chinese Americans in Hawaii. The study findings expand our understanding of psychological resources in older Chinese Americans and emphasize the importance of developing intervention programs to foster social connection and resilience among an understudied population.

A Social Media–Based Diabetes Intervention for Low-Income Mandarin-Speaking Chinese Immigrants in the United States: Feasibility Study

Hu, L., Islam, N., Trinh-Shevrin, C., Wu, B., Feldman, N., Tamura, K., Jiang, N., Lim, S., Wang, C., Bubu, O. M., Schoenthaler, A., Ogedegbe, G., & Sevick, M. A. (2022). JMIR Formative Research, 6(5). 10.2196/37737
Abstract
Abstract
Background: Chinese immigrants bear a high diabetes burden and face significant barriers to accessing diabetes self-management education (DSME) and counseling programs. Objective: The goal of this study was to examine the feasibility and acceptability and to pilot test the potential efficacy of a social media–based DSME intervention among low-income Chinese immigrants with type 2 diabetes (T2D) in New York City. Methods: This was a single group pretest and posttest study in 30 Chinese immigrants with T2D. The intervention included 24 culturally and linguistically tailored DSME videos, focusing on diabetes education and behavioral counseling techniques. Over 12 weeks, participants received 2 brief videos each week via WeChat, a free social media app popular among Chinese immigrants. Primary outcomes included the feasibility and acceptability of the intervention. Feasibility was evaluated by recruitment processes, retention rates, and the video watch rate. Acceptability was assessed via a satisfaction survey at 3 months. Secondary outcomes, that is, hemoglobin A1c (HbA1c), self-efficacy, dietary intake, and physical activity, were measured at baseline, 3 months, and 6 months. Descriptive statistics and paired 2-sided t tests were used to summarize the baseline characteristics and changes before and after the intervention. Results: The sample population (N=30) consisted of mostly females (21/30, 70%) who were married (19/30, 63%), with limited English proficiency (30/30, 100%), and the mean age was 61 (SD 7) years. Most reported an annual household income of <US $25,000 (24/30, 80%) and a high school education or less (19/30, 63%). Thirty participants were recruited within 2 months (January and February 2020), and 97% (29/30) of the participants were retained at 6 months. A video watch rate of 92% (28/30) was achieved. The mean baseline HbA1c level was 7.3% (SD 1.3%), and this level declined by 0.5% (95% CI –0.8% to –0.2%; P=.003) at 6 months. The mean satisfaction score was 9.9 (SD 0.6) out of 10, indicating a high level of satisfaction with the program. All strongly agreed or agreed that they preferred this video-based DSME over face-to-face visits. Compared to baseline, there were significant improvements in self-efficacy, dietary, and physical activity behaviors at 6 months. Conclusions: This pilot study demonstrated that a social media–based DSME intervention is feasible, acceptable, and potentially efficacious in a low-income Chinese immigrant population with T2D. Future studies need to examine the efficacy in an adequately powered clinical trial.

Wu, B., Plassman, B. L., Poole, P., Siamdoust, S., Bunn, M., Burwell, B., Pei, Y., Downey, C., Gomes, D., Kamer, A., Yu, G., Leak Bryant, A., & Anderson, R. A. (2022). BMJ Open, 12(6). 10.1136/bmjopen-2021-057099
Abstract
Abstract
Introduction Individuals with mild dementia are at high risk of poor oral health outcomes. To address this issue, we describe an intervention to teach care partners skills to guide individuals with mild dementia in proper oral hygiene techniques and provide reminders to practice oral hygiene care. By providing support to perform these tasks successfully, we aim to delay oral health decline among this vulnerable population. Methods and analysis This multisite study is a three-arm randomised controlled trial. The primary objective is to evaluate the efficacy of an intervention to improve oral hygiene outcomes by promoting positive oral hygiene behaviours and skills among individuals with mild dementia. Care partners' behaviour factors, such as oral care self-efficacy and implementation of the care plan, serve as mediators of the intervention. Participant-care partner dyads will be randomly assigned to either Treatment Group 1, Treatment Group 2 or the Control Group. All groups will receive an educational booklet. Treatment Group 1 and Treatment Group 2 will receive a smart electronic toothbrush. Treatment Group 2 (the intervention group) will also receive an oral hygiene care skill assessment, personalised oral hygiene instruction and treatment plan; and care partners will receive in-home and telephone coaching on behaviour change. Oral health outcomes will be compared across the three groups. The duration of the active intervention is 3 months, with an additional 3-month maintenance phase. Data collection will involve three home visits: baseline, 3 months and 6 months. The study enrollment started in November 2021, and the data collection will end in Spring 2024. Ethics and dissemination The study has been approved by the Institutional Review Board of the NYU Grossman School of Medicine and Duke University, and is registered at Clinicaltrials.gov. A Data Safety Monitoring Board has been constituted. The study findings will be disseminated via peer-reviewed publications, conference presentations and social media. Trial registration number NCT04390750.

Trajectories of General Health Status and Depressive Symptoms Among Persons With Cognitive Impairment in the United States

Zang, E., Guo, A., Pao, C., Lu, N., Wu, B., & Fried, T. R. (2022). Journal of Aging and Health, 34(4), 720-735. 10.1177/08982643211060948
Abstract
Abstract
ObjectivesTo identify and examine heterogeneous trajectories of general health status (GHS) and depressive symptoms (DS) among persons with cognitive impairment (PCIs). Methods: We use group-based trajectory models to study 2361 PCIs for GHS and 1927 PCIs for DS from the National Health and Aging Trends Survey 2011-2018, and apply multinomial logistic regressions to predict identified latent trajectory group memberships using individual characteristics. Results: For both GHS and DS, there were six groups of PCIs with distinct trajectories over a 7-year period. More than 40% PCIs experienced sharp declines in GHS, and 35.5% experienced persistently poor GHS. There was greater heterogeneity in DS trajectories with 55% PCIs experiencing improvement, 16.4% experiencing persistently high DS, and 30.5% experiencing deterioration. Discussion: The GHS trajectories illustrate the heavy burden of poor and declining health among PCIs. Further research is needed to understand the factors underlying stable or improving DS despite declining GHS.
