Association between tooth loss and frailty among Chinese older adults: the mediating role of dietary diversity

Xu, X., Zhao, Y., Wu, B., Pei, Y., & Gu, D. (2023). BMC Geriatrics, 23(1). 10.1186/s12877-023-04355-6
Abstract
Abstract
Background: This study aimed to examine the association between tooth loss and frailty among Chinese older adults and the mediating role of dietary diversity in this association. Methods: Data from five waves of the Chinese Longitudinal Healthy Longevity Survey conducted between 2005 and 2018 were used. Path analyses were employed to assess both concurrent and cross-lagged relationships between tooth loss and frailty index while accounting for intrapersonal correlation. Furthermore, the mediation effect of dietary diversity was also examined. Results: In concurrent models, severe tooth loss was associated with frailty after adjusting for demographic characteristics (odds ratio [OR] = 1.82, p < 0.001). The OR of frailty for severe tooth loss was only slightly decreased to 1.74 (p < 0.001) when dietary diversity was added to the model and to 1.64 (p < 0.001) when socioeconomic status, family support, and healthy lifestyles were further adjusted. In the cross-lag or longitudinal models, the ORs were mildly or moderately reduced to 1.29, 1.27, and 1.23, respectively, yet remained statistically significant (p < 0.001 or p < 0.01). The mediation analyses showed that dietary diversity had some small yet significant effects on the relationship between tooth loss and frailty in both concurrent and longitudinal settings. Conclusions: This study improves current knowledge regarding the impact of tooth loss on frailty among Chinese older adults. Future intervention strategies designed to improve healthy diets may have preventive effects against the risk of frailty among Chinese older adults with severe tooth loss.

Association Between Types of Family Support and Glycemic Control for Adults With Cognitive Impairment

Zheng, Y., Lawrence, K., Fletcher, J., Qi, X., & Wu, B. (2023). Gerontology and Geriatric Medicine, 9, 23337214231218800. 10.1177/23337214231218800
Abstract
Abstract
BACKGROUND: Family support is important in assisting with diabetes self-management for individuals with cognitive impairment, but what types of family support are most effective remain unknown.OBJECTIVES: We aimed to examine the association between the types of family support in diabetes self-management with glycemic control in middle-aged and older adults with cognitive impairment.METHODS: A total of 267 individuals were included with diabetes and cognitive impairment (27-point Telephone Interview for Cognitive Status score <12), using the data of 2003 Health and Retirement Study (HRS) Diabetes Study and 2004 wave of the HRS.RESULTS: Most respondents were White (68.9%), followed by Black (25.8%). The mean age was 73.4±8.4 years. Adults with strong family support (as indicated by a "strongly agree" response) in testing sugar and in handling feelings about diabetes had significantly lower A1C compared with those with less family support (mean ± standard deviation: 7.08±1.39 vs. 7.51±1.42, P=.03; 6.79±0.87 vs. 7.57±1.53; P=.007 respectively).CONCLUSIONS: Our findings indicate that family members of individuals with cognitive impairment provide critical support to patients with diabetes and cognitive impairment, and may need additional intervention to assist with diabetes self-management tasks that require unique knowledge and skills.

Association Between Types of Loneliness and Risks of Functional Disability in Older Men and Women: A Prospective Analysis

Qi, X., Belsky, D. W., Yang, Y. C., & Wu, B. (2023). American Journal of Geriatric Psychiatry, 31(8), 621-632. 10.1016/j.jagp.2023.02.046
Abstract
Abstract
Objective: To examine the association between types of loneliness (transient, incident, and chronic) and the risk of functional disability. Methods: Data were from the Health and Retirement Study 2006/2008-2016/2018. A total of 7,148 adults aged ≥50 was included. Functional status was measured by activities of daily living (ADL) and instrumental activities of daily living (IADL). Loneliness was assessed using the 3-item UCLA Loneliness Scale. We defined loneliness as no/transient/incident/chronic loneliness based on the pattern and duration of loneliness across 2006/2008 and 2010/2012. We applied multivariate Cox proportional hazard models with the new-onset ADL/IADL disability as outcome. Results: Overall, 69.3% respondents showed no loneliness; while 10.3%, 8.9%, and 11.5% showed transient, incident, and chronic loneliness, respectively. A total of 1,298 (18.16%) and 1,260 (17.63%) functionally normal respondents developed ADL and IADL disability during 36,294 person-years of follow-up, respectively. After adjusting for socio-demographic, behavioral, and health factors, chronic loneliness was associated with higher risks of ADL (hazard ratio [HR] = 1.37, 95% confidence interval [CI] = 1.16–1.63, p <0.001, χ2 = 3.60, degree of freedom [df] = 1) and IADL disability (HR = 1.25, 95% CI = 1.09–1.44, p = 0.002, χ2 = 3.17, df = 1) compared to no loneliness. By contrast, no significant associations between transient loneliness and ADL (HR = 1.17, 95% CI = 0.88–1.57, p = 0.273, χ2 = 1.10, df = 1) or IADL disability (HR = 1.16, 95% CI = 0.97–1.39, p = 0.112, χ2 = 1.59, df = 1) were found. Chronic loneliness was not associated with the risk of IADL disability in men (HR = 1.13, 95% CI = 0.91–1.40, p = 0.263, χ2 = 1.12, df = 1). Conclusion: Chronic loneliness, rather than transient loneliness, is an independent risk factor for functional disability in middle-aged and older adults, especially for women.

Associations of social isolation and loneliness with the onset of insomnia symptoms among middle-aged and older adults in the United States: A population-based cohort study

Qi, X., Malone, S. K., Pei, Y., Zhu, Z., & Wu, B. (2023). Psychiatry Research, 325. 10.1016/j.psychres.2023.115266
Abstract
Abstract
There is an inconsistent conclusion regarding the relationship of social isolation and loneliness with poor sleep. We investigated the associations of social isolation and loneliness with new-onset insomnia symptoms in a nationally-representative sample of 9,430 adults aged ≥50 who were free of any insomnia symptoms/sleep disorders at baseline (wave 12/13) and followed up to 4 years from the Health and Retirement Study. Social isolation was measured by Steptoe's Social Isolation Index. Loneliness was measured by the revised 3-item UCLA-Loneliness Scale. Insomnia symptoms were quantified using the modified Jenkins Sleep Questionnaire. During a mean follow-up of 3.52 years, 1,522 (16.1%) participants developed at least one insomnia symptom. Cox models showed that loneliness was associated with the onset of difficulties initiating or maintaining sleep, early-morning awakening, nonrestorative sleep, and at least one of these symptoms after adjusting for potential covariates; while social isolation was not associated with the onset of difficulties maintaining sleep, early-morning awakening, or at least one insomnia symptom after adjusting for health indicators. These results are consistent in sensitivity analyses and stratified analyses by age, sex, race/ethnicity, and obesity. Public health interventions aimed at fostering close emotional relationships may reduce the burden of poor sleep among middle-aged and older adults.

Children’s Divorce and their Financial Support to Older Parents in Rural China

Cong, Z., Pei, Y., Silverstein, M., Li, S., & Wu, B. (2023). Research on Aging, 45(2), 119-132. 10.1177/01640275221079400
Abstract
Abstract
This study examined how adult children’s divorce affected their financial support to older parents in rural China and how that relationship was dependent on children’s gender. The sample was from rural Anhui Province and the working sample included 1629 older parents who reported their interactions with 6210 children across six waves of observations in 14 years (2001–2015). Generalized Estimating Equations showed that divorced sons provided less financial support to their parents than married sons. In contrast, divorced daughters did not necessarily provide less financial support than married daughters. This gender difference was statistically significant. The findings were discussed in the context of changing rural Chinese families, where the norm of filial piety is still strong but patrilineal tradition and gender ideology have experienced desynchronized changes.

China’s Ambitious Policy Experiment with Social Long-Term Care Insurance: Promises, Challenges, and Prospects

Feng, Z., Lin, Y., Wu, B., Zhuang, X., & Glinskaya, E. (2023). Journal of Aging and Social Policy, 35(5), 705-721. 10.1080/08959420.2023.2182574
Abstract
Abstract
In 2016, China launched long-term care insurance (LTCI) pilot programs in 15 cities across the country. In this Commentary, we provide an overview of these pilots regarding the target insured population, sources of financing, beneficiary eligibility criteria, and benefit design. We offer perspectives on the strengths and limitations, implementation challenges, and future prospects of these ongoing pilots. Also, we highlight the needs for addressing several key policy issues and challenges before further expanding these programs toward national implementation. These include solidifying the LTCI financing pool for independence and self-sustainability, balancing national priorities and local needs in LTCI design, reducing coverage gaps and disparities, ensuring quality of care through pay-for-performance and regulatory oversight, and strengthening independent evaluation of LTCI implementation and impacts.

Shieu, B., Teng, C. H., Chan, Y. N., Cho, Y., Dictus, C., Wang, J., Beeber, A. S., Bryant, A., Wu, B., Plassman, B. L., & Anderson, R. A. (2023). Innovation in Aging, 7(9). 10.1093/geroni/igad123
Abstract
Abstract
Background and Objectives: Cognitive impairment is associated with poor oral health outcomes. Oral hygiene tasks are an essential target of interventions aiming to improve oral health for older adults with cognitive impairment. We aimed to examine whether experiences in an oral health intervention based on the Adaptive Leadership Framework for Chronic Illness differed between individuals with mild cognitive impairment (MCI) or mild dementia (MD) and their respective care partners. Research Design and Methods: This was a secondary analysis using directed content analysis and then an interpretive-description approach to analyze the data from a theory-driven intervention study. We included 10 people with MCI and their care partners (n = 20) and 8 people with MD and their care partners (n = 16) in the treatment arm of the intervention. For each participant, we analyzed audio recordings of 4 intervention coaching sessions, each ranging between 30 and 45 min. We managed the data and coding using ATLAS.TI software. Results: Participants in both the MCI and MD groups experienced similar challenges in adapting to changes in oral hygiene techniques, and both groups worked on learning new oral hygiene techniques taught by the dental hygienist and meeting individualized goals developed with their care partner, interventionist, and hygienist. On the other hand, there were subtle differences in technical challenges between participants in MCI and MD groups; participants in the MCI group reacted more actively to dental hygienist suggestions than the MD group. Discussion and Implications: Study findings provide information about how researchers and clinicians might tailor interventions to meet the learning needs of individuals and care partners in each group.

Creating a supportive environment for older adults in China ——exploring factors associated with the need for home modifications based on a cross-sectional survey in Central China

Li, J., Wu, B., & Wang, J. (2023). BMC Geriatrics, 23(1). 10.1186/s12877-023-04458-0
Abstract
Abstract
Background: A supportive home environment is critical to the safety and quality of life of older adults. Home modification is an effective way to build a supportive home environment for older adults’ aging in place. However, there is a lack of knowledge on older adults’ need for home modifications in China. Methods: We conducted a cross-sectional survey in three provinces of China (Hubei, Hunan, and Henan) using stratified and cluster sampling methods in 2021. A total of 5485 older adults aged 60 and over were included. The outcome variables were: need for home modifications, level of need, and type of modification needed. Exposure variables included: demographic and socioeconomic characteristics, as well as health conditions. Logistic and Poisson regressions were applied to examine the needs for home modifications and its associated factors. Results: Nearly 30% of the older adults needed home modifications. The most common choice of home modification was the need for handrails at the bedside, toilet, or threshold (31.64%), and paving un-slip tiles or vinyl flooring (17.45%). Age (IRR = 1.01, P < 0.001), education (IRR = 1.11, P < 0.01), and level of assistance (IRR = 2.31, P < 0.001) were more likely to be positively associated with needs for modification. Participants in the age group of 70 to 79 years, with primary school education, and low-level physically dependent had significantly higher needs for modifications than those of advanced age, lower level of education, or higher level of physically dependent (p < 0.01). Conclusions: The overall need for home modifications in China is low. Home modification programs are needed to tailor individuals’ needs and provide services to those with the most home modification need.

Diabetes, Edentulism, and Cognitive Decline: A 12-Year Prospective Analysis

Wu, B., Luo, H., Tan, C., Qi, X., Sloan, F. A., Kamer, A. R., Schwartz, M. D., Martinez, M., & Plassman, B. L. (2023). Journal of Dental Research, 102(8), 879-886. 10.1177/00220345231155825
Abstract
Abstract
Diabetes mellitus (DM) is a recognized risk factor for dementia, and increasing evidence shows that tooth loss is associated with cognitive impairment and dementia. However, the effect of the co-occurrence of DM and edentulism on cognitive decline is understudied. This 12-y cohort study aimed to assess the effect of the co-occurrence of DM and edentulism on cognitive decline and examine whether the effect differs by age group. Data were drawn from the 2006 to 2018 Health and Retirement Study. The study sample included 5,440 older adults aged 65 to 74 y, 3,300 aged 75 to 84 y, and 1,208 aged 85 y or older. Linear mixed-effect regression was employed to model the rates of cognitive decline stratified by age cohorts. Compared with their counterparts with neither DM nor edentulism at baseline, older adults aged 65 to 74 y (β = −1.12; 95% confidence interval [CI], −1.56 to −0.65; P < 0.001) and those aged 75 to 84 y with both conditions (β = −1.35; 95% CI, −2.09 to −0.61; P < 0.001) had a worse cognitive function. For the rate of cognitive decline, compared to those with neither condition from the same age cohort, older adults aged 65 to 74 y with both conditions declined at a higher rate (β = −0.15; 95% CI, −0.20 to −0.10; P < 0.001). Having DM alone led to an accelerated cognitive decline in older adults aged 65 to 74 y (β = −0.09; 95% CI, −0.13 to −0.05; P < 0.001); having edentulism alone led to an accelerated decline in older adults aged 65 to 74 y (β = −0.13; 95% CI, −0.17 to −0.08; P < 0.001) and older adults aged 75 to 84 (β = −0.10; 95% CI, −0.17 to −0.03; P < 0.01). Our study finds the co-occurrence of DM and edentulism led to a worse cognitive function and a faster cognitive decline in older adults aged 65 to 74 y.

Differences in the oral health status in hospitalised stroke patients according to swallowing function: A cross-sectional study

Tian, F., Li, J., Wu, B., Xiao, R., Liu, J., Yu, J., Liu, L., & Zhu, R. (2023). Journal of Clinical Nursing, 32(7), 1140-1147. 10.1111/jocn.16254
Abstract
Abstract
Background: Dysphagia is one of the common complications caused by stroke, leading to poor oral health. Oral health is often neglected after stroke by clinical care providers and the patients. Identifying the status of oral health in hospitalised stroke patients with swallowing disorders will facilitate the attention of clinical care providers. Aim: To investigate the differences in the oral health status between hospitalised post-stroke patients with dysphagia and non-dysphagia. Design: A cross-sectional study. Methods: A purposive sampling method was used to recruit participants. Participants included hospitalised post-stroke patients with dysphagia and without dysphagia. Stroke patients were recruited from the Department of Neurology, Guizhou Provincial People's Hospital in China. A total of 120 stroke patients completed the survey. The data collected included their demographics, the scores on the Oral Health Assessment Tool (OHAT), Geriatric Oral Health Assessment Index (GOHAI), and the Eating Assessment Tool-10 (EAT-10). The study was compliant with the STROBE checklist. Results: The average age of the dysphagia group was 67 (64~76) vs the participants without dysphagia group 67 (65~76), (p =.610). The mean standard deviation (SD) OHAT score of participants with dysphagia was 5.28 (2.33) compared to participants without dysphagia 8.89 (3.07), (p <.05). This result indicates post-stroke dysphagia (PSD) patients had worse oral health than stroke patients without dysphagia. Binary logistic regression analysis showed that oral health status was the independent influencing factor of swallowing function (p <.01). Conclusion: The participants with dysphagia had worse oral health status compared to those without dysphagia, illustrating the critical importance of improving attention to oral health management in patients with post-stroke swallowing disorders. Relevance to clinical practice: Oral health was often omitted when comparing to other functional impairments resulting from stroke. Health caregivers of post-stroke patients with dysphagia should be aware of the importance of evaluating patient’s oral condition and implementing oral care.
