Age at Migration and Cognitive Health Among Chinese Older Immigrants in the United States

Guo, M., Li, M., Xu, H., Stensland, M., Wu, B., & Dong, X. Q. (2021). Journal of Aging and Health, 33(9), 709-720. 10.1177/08982643211006612
Abstract
Abstract
Objectives: This study addressed two questions: (1) Is age at migration associated with cognitive function among Chinese older immigrants? and (2) what personal and environmental factors confound the above relationship? Methods: Data were derived from the Population Study of Chinese Elderly (N = 2957). Quantile and linear regressions were used to examine the associations between age at migration and Mini-Mental State Examination (MMSE) and global cognitive function, respectively. Results: Migration in late middle age (50–64) or late adulthood (65 or older) was associated with lower MMSE scores. Global cognition did not vary by age at migration. Associations between age at migration and MMSE were stronger among individuals with lower education or social engagement. Discussion: Migrating late in one’s life has important implications for cognitive health over the life course. Findings are helpful to identify vulnerable older immigrant segments and provide tailored interventions to promote their cognitive health.

Assessment of Coronavirus Disease 2019 Infection and Mortality Rates Among Nursing Homes With Different Proportions of Black Residents

Travers, J. L., Agarwal, M., Estrada, L. V., Dick, A. W., Gracner, T., Wu, B., & Stone, P. W. (2021). Journal of the American Medical Directors Association, 22(4), 893-898.e2. 10.1016/j.jamda.2021.02.014
Abstract
Abstract
Objective: Coronavirus disease 2019 (COVID-19) has disproportionately impacted nursing homes (NHs) with large shares of Black residents. We examined the associations between the proportion of Black residents in NHs and COVID-19 infections and deaths, accounting for structural bias (operationalized as county-level factors) and stratifying by urbanicity/rurality. Design: This was a cross-sectional observational cohort study using publicly available data from the LTCfocus, Centers for Disease Control and Prevention Long-Term Care Facility COVID-19 Module, and the NYTimes county-level COVID-19 database. Four multivariable linear regression models omitting and including facility characteristics, COVID-19 burden, and county-level fixed effects were estimated. Setting and Participants: In total, 11,587 US NHs that reported data on COVID-19 to the Centers for Disease Control and Prevention and had data in LTCfocus and NYTimes from January 20, 2020 through July 19, 2020. Measures: Proportion of Black residents in NHs (exposure); COVID-19 infections and deaths (main outcomes). Results: The proportion of Black residents in NHs were as follows: none= 3639 (31.4%), <20% = 1020 (8.8%), 20%-49.9% = 1586 (13.7%), ≥50% = 681 (5.9%), not reported = 4661 (40.2%). NHs with any Black residents showed significantly more COVID-19 infections and deaths than NHs with no Black residents. There were 13.6 percentage points more infections and 3.5 percentage points more deaths in NHs with ≥50% Black residents than in NHs with no Black residents (P <.001). Although facility characteristics explained some of the differences found in multivariable analyses, county-level factors and rurality explained more of the differences. Conclusions and Implications: It is likely that attributes of place, such as resources, services, and providers, important to equitable care and health outcomes are not readily available to counties where NHs have greater proportions of Black residents. Structural bias may underlie these inequities. It is imperative that support be provided to NHs that serve greater proportions of Black residents while considering the rurality of the NH setting.

Association between childhood conditions and arthritis among middle-aged and older adults in China: The China Health and Retirement Longitudinal Study

Lu, N., Wu, B., Jiang, N., & Dong, T. (2021). Ageing and Society, 41(11), 2484-2501. 10.1017/S0144686X20000343
Abstract
Abstract
This study examined the association between childhood conditions and arthritis among middle-aged and older adults in China. The data were derived from the 2015 wave and the life-history module of the China Health and Retirement Longitudinal Study. Face-to-face interviews were conducted with respondents age 45 and over across China. Multiple imputation was used to handle the missing data, generating a final analytic sample of 19,800. Doctor-diagnosed arthritis was the main outcome variable. Random-effects logistic regression models were used to test the proposed models. Approximately 8 per cent of the respondents had better family financial status in childhood than their neighbours. Close to 8 per cent had been hospitalised or encountered similar conditions (e.g. confined to bed or home) for at least one month in childhood. Around one-third reported better subjective health in childhood than their peers. The majority of the respondents (80%) reported that they had stable health resources, and that their mothers were illiterate during their childhood. Childhood family financial status, subjective health, mother's education, access to health care and medical catastrophic events were found to be significant factors associated with arthritis in later life, after controlling for adulthood and older-age conditions (family financial status: odds ratio (OR) = 0.885, 95 per cent confidence interval (95% CI) = 0.848-0.924; subjective health: OR = 0.924, 95% CI = 0.889-0.960; mother's education: OR = 0.863, 95% CI = 0.750-0.992; access to health care: OR = 0.729, 95% CI = 0.552-0.964; medical catastrophic events: OR = 1.266, 95% CI = 1.108-1.446). The study results highlight an important role that childhood conditions play in affecting the onset of arthritis in late life in China. Health-care providers may consider childhood conditions as a valuable screening criterion to identify risk populations, which could be used to guide health promotion and prevention programmes, and promote healthy ageing.

Association between home health agency ownership status and discharge to community among Medicare beneficiaries

Basu, R., Wu, B., Luo, H., & Allgood, L. (2021). Home Health Care Services Quarterly, 40(4), 340-354. 10.1080/01621424.2021.1984360
Abstract
Abstract
To investigate the association of ownership status, discharge rate and length of stay (LOS) of home health care (HH) services under the prospective payment system (PPS). We used 2016–2018 Outcome Assessment and Information Set (OASIS) data sets for Medicare beneficiaries. Two outcome variables were investigated: rate of discharge from an HH agency and LOS. Our main independent variable was ownership status: for-profit (FP) versus not-for-profit (NFP). FP agencies were 4.2% (p <.01) less likely to discharge patients to the community but more likely (7.3%; p <.001) to have longer LOS (>99 days) compared to NFPs. Findings that FP agencies were less likely to discharge patients to the community and more likely to have a longer length of stay than NFP agencies have implications for quality of care initiatives by the Medicare Post-Acute Transformation Act 2014.

Association between primary caregiver type and mortality among Chinese older adults with disability: a prospective cohort study

Liu, Y., Li, H., Wu, B., Liu, X., Chen, H., Jin, H. Y., & Wu, C. (2021). BMC Geriatrics, 21(1). 10.1186/s12877-021-02219-5
Abstract
Abstract
Background: Socio-demographic transitions have dramatically changed the traditional family care settings in China, caused unmet care needs among older adults. However, whether different primary caregiver types have different influences on disabled older adults’ health outcomes remain poorly understood. We aimed to examine the association between the type of primary caregiver (e.g., spouse and children) and death among community-dwelling Chinese older adults disabled in activities of daily living. Methods: We used data from Chinese Longitudinal Healthy Longevity Survey. The analytic sample comprised 4278 eligible adults aged ≥ 80 years. We classified primary caregiver type into five categories: spouse, son/daughter-in-law, daughter/son-in-law, grandchildren, and domestic helper. We used Cox regression model to examine the association between primary caregiver type and all-cause mortality. Covariates included age, sex, residence, years of education, co-residence status, financial independence, whether living with children, number of ADL disability, number of chronic conditions, and self-reported health, cognitive impairment, and caregiving quality. Results: Married older adults whose primary caregivers were son/daughter-in-law had a 38% higher hazard of death than those who had spouse as the primary caregiver. Married men who received care primarily from son/daughter-in-law or daughter/son-in-law had a 64 and 68% higher hazard of death, respectively, than those whose primary caregiver was spouse. The association between primary caregiver type and mortality among widowed older adults differed between urban and rural areas. Urban residents who had domestic helpers as the primary caregiver had an 16% lower hazard of death, while those living in rural areas had a 50% higher hazard of death, than those having son/daughter-in-law as the primary caregiver. Conclusions: The quality of care of the primary caregiver may be a risk factor for mortality of disabled older adults in China. Interventions are necessary for reducing unmet needs and managing care burden.

Care partner–assisted intervention to improve oral health for older adults with cognitive impairment: A feasibility study

Wu, B., Anderson, R. A., Pei, Y., Xu, H., Nye, K., Poole, P., Bunn, M., Lynn Downey, C., & Plassman, B. L. (2021). Gerodontology, 38(3), 308-316. 10.1111/ger.12528
Abstract
Abstract
Background and Objectives: Older adults with cognitive impairment often experience poor oral health outcomes due to inadequate oral hygiene practices. This pilot study aimed to evaluate the feasibility of a care partner–assisted intervention to improve the oral hygiene of community-dwelling older adults with cognitive impairment. Material and Methods: The 6-month intervention included 25 older adults with mild dementia or mild cognitive impairment, who were randomly assigned to Treatment Group 1 or Treatment Group 2. Treatment Group 1 (n = 7) received an educational booklet. Treatment Group 2 (n = 18) received a booklet, a tailored care plan for the participants with cognitive impairment and the care partner received four coaching sessions to learn to facilitate good oral hygiene. Both groups received electric toothbrushes. The study consisted of a 3-month active intervention and 3-month maintenance phase. The outcomes of gingival index, plaque index and overall oral health status based on the Oral Health Assessment Tool were measured at baseline, 3 months (end of active intervention) and 6 months of the study. Results: This study had very low dropout rate. Participants’ oral hygiene improved in this study. In comparison to Treatment Group 1, participants in Treatment Group 2 had a greater reduction in plaque level and gingival inflammation, and greater improvement in overall oral health status. Conclusion: This study demonstrates the feasibility of this intervention designed to improve the oral health of persons with cognitive impairment and it lays the foundation for using this protocol in a future large randomised clinical trial.

The Compliance of End-of-Life Care Preferences Among Older Adults and Its Facilitators and Barriers: A Scoping Review

Master, J. F., Wu, B., Ni, P., & Mao, J. (2021). Journal of the American Medical Directors Association, 22(11), 2273-2280.e2. 10.1016/j.jamda.2021.05.007
Abstract
Abstract
Objectives: To explore the compliance of end-of-life (EOL) care preferences, and the facilitators and barriers of promoting quality of EOL care among older adults. Design: A scoping review was used to identify key themes in the compliance of EOL care preferences among older adults. Setting and participants: Studies published between 2009 and 2020 were identified from the Medline and Cochrane libraries. Eligible articles containing components related to the compliance of EOL care preferences among older adults were selected. Measures: The eligible articles were thematically synthesized. Factors that affected the compliance of EOL care preferences among older adults were identified from the key components. Results: In total, 35 articles were included to identify the key components in the compliance of EOL care preferences: (1) supportive policy, (2) supportive environment, (3) cultural characteristics, (4) advance care planning (ACP), (5) the concordance of EOL care preferences between patients and surrogate decision makers, (6) prognosis awareness, and (7) patient's health status and the type of disease. Facilitators for the compliance of EOL care preferences included enactment of relevant policy, sufficient care institutions, the utilization of ACP, and poor health status. Barriers included lack of supportive policy, different culture, and low utilization of ACP. Conclusions/Implications: The compliance of EOL care preferences was low among older adults. The compliance of EOL care preferences can be improved through relevant policy development and the utilization of ACP.

The development of a personalized symptom management mobile health application for persons living with hiv in China

Han, S., Pei, Y., Wang, L., Hu, Y., Qi, X., Zhao, R., Zhang, L., Sun, W., Zhu, Z., & Wu, B. (2021). Journal of Personalized Medicine, 11(5). 10.3390/jpm11050346
Abstract
Abstract
Persons living with HIV (PLWH) continuously experience symptom burdens. Their symptom prevalence and severity are also quite different. Mobile health (mHealth) applications (apps) offer exceptional opportunities for using personalized interventions when and where PLWH are needed. This study aimed to demonstrate the development process of the symptom management (SM) app and the structure and content of it. Our research team systematically searched for evidence-based resources and summarized up-to-date evidence for symptom management and health education. Our multidisciplinary research team that included physicians, nurses, software engineers, and nursing professors, evaluated the structure and content of the drafted app. Both quantitative data and qualitative results were collected at a group discussion meeting. Quantitative data were scores of sufficient evidence, situational suitability, practicability, cost-effectiveness, and understandability (ranged from one to four) for 119 items of the app contents, including the health tracking module, the self-assessment module, coping strategies for 18 symptoms (80 items), medication management, complementary therapy, diet management, exercise, relaxation techniques, and the obtaining support module. The SM app was comprised of eight modules and provided several personalized symptom management functions, including assessing symptoms and receiving different symptom management strategies, tracking health indicators, and communicating with medical staff. The SM app was a promising and flexible tool for HIV symptom management. It provided PLWH with personalized symptom management strategies and facilitated the case management for medical staff. Future studies are needed to further test the app’s usability among PLWH users and its effects on symptom management.

Dose-Response Meta-Analysis on Tooth Loss With the Risk of Cognitive Impairment and Dementia

Qi, X., Zhu, Z., Plassman, B. L., & Wu, B. (2021). Journal of the American Medical Directors Association, 22(10), 2039-2045. 10.1016/j.jamda.2021.05.009
Abstract
Abstract
Objectives: To quantify the dose-response associations between tooth loss and risk of cognitive impairment and dementia. Design: Longitudinal studies that examined the association between tooth loss and cognitive function were systematically searched on 6 databases through March 1, 2020. The study adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Risk estimates were pooled using random-effects models. The dose-response associations were assessed using generalized least squares spline models. Setting and Participants: Adults from community, institution, outpatient or in-hospital were included in the meta-analysis. Measures: Cognitive impairment and dementia were defined by neuropsychological tests, diagnostic criteria, or medical records. Tooth loss was self-reported or assessed by clinical examinations. Results: Fourteen studies were entered into the meta-analysis, including 34,074 participants and 4689 cases with diminished cognitive function. Participants with more tooth loss had a 1.48 times higher risk of developing cognitive impairment [95% confidence interval (CI) 1.18–1.87] and 1.28 times higher risk of being diagnosed with dementia (95% CI 1.09–1.49); however, the association was nonsignificant for participants using dentures (relative risk = 1.10, 95% CI 0.90–1.11). Eight studies were included in the dose-response analysis, and data supported the use of linear models. Each additional tooth loss was associated with a 0.014 increased relative risk of cognitive impairment and 0.011 elevated relative risks of dementia. Edentulous participants faced a 1.54 times higher risk of cognitive impairment and a 1.40 times higher risk of being diagnosed with dementia. Conclusions and Implications: Moderate-quality evidence suggested tooth loss was independently associated with cognitive impairment and dementia; risk of diminished cognitive function increased with incremental numbers of teeth lost. Furthermore, timely prosthodontic treatment with dentures may reduce the progression of cognitive decline related to tooth loss.

Effects of a symptom management intervention based on group sessions combined with a mobile health application for persons living with HIV in China: A randomized controlled trial

Han, S., Pei, Y., Zhao, R., Hu, Y., Zhang, L., Qi, X., Zhu, Z., Sun, W., & Wu, B. (2021). International Journal of Nursing Sciences, 8(4), 370-379. 10.1016/j.ijnss.2021.07.002
Abstract
Abstract
Objective: This study aims to evaluate the effects of a symptom management intervention (SMI) based on symptom management group sessions combined with a mobile health (mHealth) application (app) on the knowledge of symptom management, the certainty of symptom self-management, symptom severity, symptom distress, medication adherence, social support, and quality of life among persons living with HIV (PLWH) in China. Methods: A parallel randomized controlled trial with 61 PLWH was conducted in Shanghai, China. The participants in the control group (n = 30) downloaded the Symptom Management (SM) app according to their needs and preferences, and received routine follow-ups. The participants in the intervention group (n = 31) were guided to download and use the SM app, and received four tailored weekly group sessions at routine follow-ups. Each group session lasted for approximately 2 h and targeted one of the major modules of the SM app. All the outcomes were assessed at baseline and post-intervention. The study was registered with the Chinese Clinical Trial Registry (ChiCTR1900024821). Results: The symptom management knowledge and certainty of symptom self-management were significantly improved after the intervention (all P < 0.01). Compared with the control group, the scores of symptoms reasons knowledge score improved 11.47 points (95% CI: 3.41, 19.53) and scores of symptoms self-management knowledge score improved 12.80 points (95% CI: 4.55, 21.05) in the intervention group after controlling for covariates. However, other outcomes did not show statistically significant differences between the intervention group and the control group (P > 0.05). Conclusion: The SMI could improve PLWH's symptom management knowledge and certainty of symptom self-management. Multi-center studies with larger sample sizes and longer follow-ups are needed to further understand the effects of SM app on ameliorating symptom severity and symptom distress. More innovative strategies are also needed to promote and maintain the sustainability of the SM app.
