Age at diagnosis of diabetes, obesity, and the risk of dementia among adult patients with type 2 diabetes

Qi, X., Zhu, Z., Luo, H., Schwartz, M. D., & Wu, B. (2024). PloS One, 19(11). 10.1371/journal.pone.0310964

Abstract

Abstract

Background While Type 2 Diabetes Mellitus (T2DM) prevalence is increasing among younger individuals, few studies have examined how age at T2DM diagnosis relates to dementia risk in diabetic populations. We aimed to investigate the association between age at T2DM diagnosis and subsequent dementia risk, and to determine whether obesity moderates this relationship. Methods We conducted a prospective cohort study using data from the Health and Retirement Study (2002–2016) matched with its 2003 Diabetes Mail-Out Survey. The study included 1,213 dementia-free adults aged ≥50 with diagnosed T2DM. Primary exposures were age at T2DM diagnosis (categorized as <50, 50–59, 60–69, and ≥70 years) and obesity status (BMI ≥30 kg/m2). The outcome was incident dementia, assessed using the Telephone Interview for Cognitive Status. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for sociodemographic factors, health behaviors, health status, and diabetes medication use. Results Over a median follow-up of 10 (interquartile range, 6–14) years, 216 (17.8%) participants developed dementia. Compared to participants diagnosed with T2DM at age ≥70 years, those diagnosed at younger ages had increased dementia risk: HR 1.70 (95% CI, 1.03–2.80) for 60–69 years, 1.72 (95% CI, 1.06–2.79) for 50–59 years, and 1.90 (95% CI, 1.14–3.18) for <50 years. Obesity significantly moderated this relationship, with obese individuals diagnosed with T2DM before age 50 showing the highest dementia risk (HR 3.05; 95% CI 1.23–7.56) compared to non-obese individuals diagnosed at ≥50 years. Conclusions Younger age at diagnosis of T2DM was significantly associated with a higher risk of dementia, particularly among individuals with obesity. Interventions specifically targeting obesity may be more effective in preventing dementia for adults with a younger onset of T2DM.

Abstract

Abstract

INTRODUCTION: This study examines the associations of gum treatment with cognitive decline and dementia risk among older adults with periodontal symptoms in the USA.METHODS: A cohort of 866 adults aged ≥50 with periodontal symptoms was recruited for the 2008 Health and Retirement Study "Dental Health Experimental Module" and followed until 2020. Cognitive function was assessed with the Telephone Interview for Cognitive Status (TICS). Dementia status was ascertained with the Langa-Weir algorithm based on TICS scores and proxy assessments. Linear mixed-effects model and multivariable Cox regression models were utilized to analyze the associations of gum treatment with cognitive decline and the risk of dementia, respectively.RESULTS: Of 866 participants (mean age 67.7, 61.4% women), 105 (12.1%) developed dementia with a median follow-up of 9 (IQR, 6-10) years. The dementia incidence rates were lower in the group with gum treatment (7.4 vs. 12.9 per 1,000 person-years). Compared with participants who did not have gum treatment, those with gum treatment experienced a decline in TICS score that was on average 0.025 (95% CI, 0.005-0.044) points less per year and a 38% lower incidence of dementia (hazard ratio, 0.62; 95% CI, 0.41-0.93). These associations were consistent across participants with a different severity of periodontal symptoms and sociodemographic characteristics (age, sex, race, ethnicity, and education) except for income levels.CONCLUSION: Prompt gum treatment for older adults with periodontal symptoms may be beneficial for their cognitive health.

Can formal home and community-based care substitute informal care? Evidence from Chinese Longitudinal Healthy Longevity Survey

Wang, Y., Wu, B., & Yang, W. (2024). BMC Geriatrics, 24(1). 10.1186/s12877-024-05312-7

Abstract

Abstract

Background: Formal home and community-based care are often considered as the preferable option to institutional care, offering older individuals the convenience of receiving care in their homes. Although research has found that these services may alleviate the burden on informal caregivers, there is a lack of research on which specific types of formal home and community-based care influence informal care provision. Methods: Employing fixed-effects and quantile regression models, this study seeks to explore the effects that various formal home and community-based care services have on reducing the burden of informal care. This study draws data from the Chinese Longitudinal Healthy Longevity Survey 2005, 2008, 2011, 2014, and 2018. Results: Our findings indicate that two types of formal care substantially influence the provision of informal care. The availability of daily living assistance services correlates with reduced informal caregiving hours, especially for those with extensive care needs. The availability of community-based health care services is linked to a reduction in the direct expenses incurred from informal caregiving, especially for those incurring greater direct caregiving costs. These effects are more prominent among urban residents. Other services, such as mental health support and legal advice services, do not demonstrate significant effects on reducing informal care hours and costs. Conclusions: Daily living assistance and community-based health care services play a crucial role in benefiting informal caregivers. It is important to prioritize the expansion of these services, especially among those with greater care needs.

Bryant, A. L., Hirschey, R., Caiola, C. E., Chan, Y. N., Cho, Y., Plassman, B. L., Wu, B., Anderson, R. A., & Bailey, D. E. (2024). Geriatric Nursing, 56, 40-45. 10.1016/j.gerinurse.2023.12.021

Abstract

Abstract

Oral health declines in older adults with cognitive impairment. We aimed to improve oral hygiene outcomes for individuals with mild cognitive impairment (MCI) or mild dementia (MD) by fostering behavior changes among carepartners assisting them. We used qualitative data of verbatim transcripts of coaching sessions with carepartners (n = 17 dyads:10 dyads for MCI, 7 dyads for MD). Directed and emergent coding were used to understand behavior change techniques (BCTs). BCTs were compared with carepartners of participants with MCI and MD. Most frequently used BCTs in both groups: prompts and cues, instruction on how to perform the behavior, review behavioral goal, and problem solving. Different BCTs emerged in study: social support-unspecified of the MCI group and credible source for MD group. Findings clarified active intervention components, common BCTs used by carepartners, and different BCT approaches for both participants. Findings help to elucidate the mechanisms of changes in individuals’ behaviors in these interventions.

Caregiving in Asia: Priority areas for research, policy, and practice to support family caregivers

Jiang, N., Wu, B., & Li, Y. (2024). Health Care Science, 3(6), 374-382. 10.1002/hcs2.124

Abstract

Abstract

Population aging presents a growing societal challenge and imposes a heavy burden on the healthcare system in many Asian countries. Given the limited availability of formal long-term care (LTC) facilities and personnel, family caregivers play a vital role in providing care for the increasing population of older adults. While awareness of the challenges faced by caregivers is rising, discussions often remain within academic circles, resulting in the lived experiences, well-being, and needs of family caregivers being frequently overlooked. In this review, we identify four key priority areas to advance research, practice, and policy related to family caregivers in Asia: (1) Emphasizing family caregivers as sociocultural navigators in the healthcare system; (2) addressing the mental and physical health needs of family caregivers; (3) recognizing the diverse caregiving experiences across different cultural backgrounds, socioeconomic status, and countries of residence; and (4) strengthening policy support for family caregivers. Our review also identifies deficiencies in institutional LTC and underscores the importance of providing training and empowerment to caregivers. Policymakers, practitioners, and researchers interested in supporting family caregivers should prioritize these key areas to tackle the challenge of population aging in Asian countries. Cross-country knowledge exchange and capacity development are crucial for better serving both the aging population and their caregivers.

Mao, W., Wu, B., Zhang, F., & Yang, W. (2024). Gerontologist, 64(11). 10.1093/geront/gnae133

Abstract

Abstract

Background and Objectives: Dental care utilization is an important, yet understudied aspect of healthcare in informal caregivers of persons with dementia. This study examined how caregiving-related characteristics are associated with dental care utilization among U.S. informal caregivers of persons with dementia and further examined gender differences. Research Design and Methods: Pooled data came from the Behavioral Risk Factor Surveillance System in 2016, 2018, 2020, and 2022. A nationally representative sample of informal caregivers (n = 3,909) was included. Dental care utilization was "yes"versus "no"within the past year. Caregiving-related characteristics included caregiver role, intensity of care, duration of care, and type of care. Logistic regressions and subgroup analyses were conducted. Results: In total sample, compared to adult child caregivers, spousal caregivers were 28% less likely to visit a dentist (odds ratio [OR] = 0.72; 95% confidence interval [CI] = 0.56, 0.94). Caregivers who provided care for more than 20 hr per week were 18% less likely to visit a dentist (OR = 0.82; 95% CI = 0.69, 0.98). In subgroup analyses, intensity of care was a barrier to dental care utilization for female caregivers (OR = 0.78; 95% CI = 0.62, 0.98), whereas caregiver role such as spousal caregiver (OR = 0.59; 95% CI = 0.39, 0.89) or other relative caregiver (OR = 0.70; 95% CI = 0.50, 0.99) was a barrier to dental care utilization for male caregivers. Discussion and Implications: The findings highlight the importance of caregiving-related characteristics in dental care utilization and suggest gender-tailored interventions.
