Association between willingness to exercise and incident disability in older adults: a prospective longitudinal cohort study.

PURPOSE: To investigate whether the willingness to exercise (WTE) and exercise habits affect the incidence of disability among older adults. METHODS: This study included 8,354 individuals (72.5 ± 6.2 years, 55.9% female). The participants were divided into three categories based on their WTE: unwillingness to exercise, willingness to exercise (but without exercise habits), and exercise habits. The incidence of disability was prospectively determined within 24 months of the follow-up. Cox regression analysis was used to examine the relationship between WTE and the incidence of disability. RESULTS: Overall, 600 (7.2%), 4,703 (56.3%), and 3,051 (36.5%) participants were classified as unwillingness to exercise, willingness to exercise, and exercise habits, respectively. Compared with the unwillingness to exercise group, the willingness to exercise group (hazard ratio [HR] 0.71, 95%Confidence Interval [CI] 0.52-0.96) and the exercise habits group (HR 0.65, 95%CI 0.46-0.92) had a lower risk of disability incidence. CONCLUSIONS: These results suggest that WTE reduces the risk of disability in older adults. Therefore, the importance of increasing WTE to prevent the occurrence of disabilities is clear. Our results suggest that even though physical activity declines with age, it is important to have the desire to exercise and develop exercise habits.

Can long-term care insurance prevent worsening of frailty among older Chinese adults? A difference-in-differences study based on CHARLS data.

Frailty, which is accompanied by negative health outcomes associated with aging, is an increasingly serious public health problem. Long-term care insurance (LTCI) is an effective intervention for frailty in older adults, but few studies have linked LTCI to frailty prevention. This study aimed to determine the role of LTCI in preventing worsening of frailty in older adults. This study used five-wave panel data from the China Health and Retirement Longitudinal Study (CHARLS) 2011 to 2020 to construct an indicator system to assess the frailty index (FI) of surveyed older adults and used a difference-in-differences (DID) method to assess the policy effect of LTCI on frailty among older adults. We found that the full-sample mean of the FI of older adults in China was 0.196, and the implementation of LTCI had a significant negative effect on the FI of older adults. The effect was heterogeneous across sex, age, education and medical insurance groups. LTCI had a more significant negative effect on male group, the middle-aged group, the less educated group, and the URRBMI group, while the effect was less significant for the female and the UEBMI group, and not significant for the more educated and other age groups. That is to say, older Chinese adults are generally frail to different degrees, and the implementation of a LTCI system can prevent worsening of frailty among them, but the effect is not equal across populations. The institutional coverage of LTCI should be further strengthened in the future to slow down the frailty process of the enrollees, so as to promote healthy aging.

The impact of long-term care insurance on the utilization of inpatient service: Evidence and mechanisms in China.

This paper empirically investigates the impact of public long-term care insurance (LTCI) on the utilization of inpatient services and associated expenditures among disabled Chinese individuals, using data from the China Health and Retirement Longitudinal Study from 2011 to 2018. Employing a staggered difference-in-difference approach within a propensity score matching framework (PSM-DID), the study finds that the introduction of LTCI significantly reduces the likelihood of inpatient service usage by 4.2%, the annual number of inpatient admissions by 10.2%, the annual inpatient cost by 16.2%, the out-of-pocket expenses by 20.7%, and the reimbursement expenditure by the public medical insurer by 9.9%. The study further explores the mechanisms underlying these effects and identifies that the Substitution Effect, where care services in community healthcare centers and nursing homes replace hospitalizations, outweighs the Income Effect generated by LTCI benefits. By leveraging the quasi-natural experimental setting of diverse LTCI policies across cities, the study also examines the heterogeneous impacts of LTCI based on household income, eligibility criteria, and reimbursement methods. The findings underscore the positive role of LTCI in controlling medical expenses and alleviating congestion in urban hospitals, offering valuable insights for promoting "Healthy Aging".

Mortality in elderly Parkinson's disease patients with long-term care needs: A nationwide population-based study in Korea.

BACKGROUND: The effects of long-term care insurance (LTCI) in reducing medical costs and utilization among older adults have been reported. This study aims to investigate the mortality in patients with Parkinson's disease (PD) requiring LTCI and its relationships with economic status. METHODS: This study was conducted using the database of the Korean National Health Insurance Service (NHIS)-Senior Cohort between 2008 and 2019. A total of 5937 patients with PD were included. Hazard ratios (HRs) of mortality associated with LTCI were estimated using a Cox regression model. Potential confounders such as demographics and comorbidities were adjusted. RESULTS: Out of 5937 PD patients, 821 required LTCI, and 5116 did not. Compared to PD patients without LTCI, PD patients with LTCI were older and exhibited a higher comorbidity burden. The overall incidence rate of mortality was 18.63 per 100 person-years in PD patients with LTCI. PD patients requiring LTCI were associated with an increased HR of 3.61 (95 % CI = 3.13-4.16) for mortality compared to PD patients not eligible for LTCI. Low-income status with LTCI was associated with the highest mortality risk (HR = 4.54, 95 % CI = 3.38-6.09), compared to middle-income status (HR = 3.47, 95 % CI = 2.64-4.61) and high-income status (HR = 3.53, 95 % CI = 2.91-4.91). CONCLUSIONS: Our study suggests that older PD patients requiring LTCI with low economic status have a higher risk of death. Continuous policy efforts to reduce the mortality risk in this group are needed.

Development of a practical framework and indicators for monitoring integrated long-term health and care needs and service use.

This case study presents an evidence-building approach to support policy planning for integrated health and care delivery for older adults. We developed an integrated needs-assessment framework to monitor the complex long-term medical and care needs of older individuals, using routinely collected, standardized needs-assessment and utilization data from the public health and long-term care (LTC) insurance systems in South Korea. We also developed a set of misuse indicators and analyzed service utilization patterns, while accounting for their varying types of needs. Approximately 11 % of older Koreans were identified as having complex long-term medical and care needs, which were categorized into four distinct need groups. More than one-third of those in the higher-medical/lower-care needs group stayed in LTC hospitals for six months or more during the year, and about one-third of those in the higher-medical/higher-care needs group inappropriately resided in LTC facilities, where medical services are limited. The newly developed integrated needs-assessment framework and misuse indicator set provide practical tools for monitoring the extent and nature of complex needs, as well as patterns of over- or under-utilization of health and care services over time. The empirical evidence gathered here highlights the need for reforms in South Korea's health and LTC systems.

Sex- and Age-Specific Associations Between Metabolic Syndrome and Future Functional Disability in the Japanese Older Population.

Whether the association between metabolic syndrome (MetS) and functional disability differs depending on sex or age remains unknown. To determine the association between MetS and functional disability in older people separately by sex and age groups. A total of 11 083 participants (4407 men and 6676 women) aged 65 years or over without functional disability were enrolled. MetS was defined according to the revised NCEP ATP III guidelines. Functional disability was defined by a new certification in the long-term care insurance in Japan. Cox proportional hazards models were used to assess the risk of functional disability with adjustment for possible confounding factors. Over the mean observation period of 10.5 years, 1282 men and 2162 women experienced functional disability. For those aged 65 to 74 years, HRs (95% CIs) for functional disability in the MetS group were 1.33 (1.07-1.66) in men and 1.15 (1.000-1.32) in women. For those aged 75 years or older, there was no significant association in men or women. In subjects with a severe care need level, there was a marginal significant association in men aged 65 to 74 years. Among the MetS components that independently increased the risk of functional disability were glucose intolerance and elevated blood pressure (men and women aged 65-74 years), obesity (women aged 65-74 years), and glucose intolerance (women aged 75 years or older). MetS contributed to an increase in a high risk of future functional disability among individuals aged 65 to 74 years. In this age group, improvement of lifestyle, health promotion and interventions for MetS from middle age may prevent future functional disability.

Technical Efficiency of Prevention Services for Functional Dependency in Japan's Public Long-term Care Insurance System: An Ecological Study.

BACKGROUND: Public long-term care insurance (LTCI) systems can promote equal and wider access to quality long-term care. However, ensuring the financial sustainability is challenging owing to growing care demand related to population aging. To control growing demand, Japan's public LTCI system uniquely provided home- and community-based prevention services for functional dependency for older people (ie, adult day care, nursing care, home care, functional screening, functional training, health education, and support for social activities), following nationwide protocols with decentralized delivery from 2006 until 2015. However, evaluations of the effects of these services have been inconclusive. METHODS: We estimated the marginal gain and technical efficiency of local prevention services using 2009-2014 panel data for 474 local public insurers in Japan, based on stochastic frontier analysis. The outcome was the transformed sex-and age-adjusted ratio of the observed to expected number of individuals aged ≥65 years certified for moderate care. Higher outcome values indicate lower population risk of moderate functional dependency in each region in each year. The marginal gains of the provided quantities of prevention services as explanatory variables were estimated, adjusting for regional medical and welfare access, care demand and supply, and other regional factors as covariates. RESULTS: Prevention services (except functional screening) significantly reduced the population risk of moderate functional dependency. Specifically, the mean changes in outcome per 1% increase in adult day care, other nursing care, and home care were 0.13%, 0.07%, and 0.04%, respectively. The median technical efficiency of local public insurers was 0.94 (interquartile range: 0.89-0.99). CONCLUSION: These findings suggest that population-based services with decentralized local operation following standardized protocols could achieve efficient prevention across regions. This study could inform current discussions about the range of benefit coverage in public LTCI systems by presenting a useful option for the provision of preventive benefits.

Can Long-Term Care Insurance Change Eldercare Patterns? Evidence from China.

Long-term Care Insurance (LTCI), providing care services and economic compensation to older adults with activity limitations, plays a crucial role in addressing the care needs of older adults and easing the burden on family caregivers. This article is based on the 2011-2018 China Health and Retirement Longitudinal Study (CHARLS) and uses China's LTCI pilot program as a quasi-experiment to examine the impact of LTCI on older adults' care patterns in China. It employs a staggered difference-in-differences (staggered DID) methodology to model the economic support, living arrangements and care, and spiritual comfort provided to older adults. Results indicate that LTCI significantly enhances the economic and emotional independence of older adults. On the one hand, LTCI effectively decreases the economic and emotional dependence of older adults on their children. On the other hand, LTCI raises the likelihood that older adults rely on social institutions and personnel for care. Additionally, LTCI is associated with achieving higher life satisfaction. Interestingly, the impact of LTCI varies significantly across sub-samples of different types of older adults and different policy regulations. Overall, findings indicate that LTCI shifts older adults' care patterns from family to socialized care, thereby reducing children's caregiving burden.

The effect of long-term care insurance on women's health outcomes in China: evidence from a disability inclusion action.

BACKGROUND: Long-term care insurance (LTCI) in China provides financial and care security for persons with disabilities and includes caregivers in the paid labour workforce. However, it is unclear how the LTCI affects health outcomes in female recipients, female caregivers, and female non-recipients and female non-caregivers. METHODS: Using the China Health and Retirement Longitudinal Study data and staggered difference-in-differences method, we evaluated the effect of LTCI on health outcomes in women with different roles, including female recipients, female caregivers, and female non-recipients and female non-caregivers, and discussed the heterogeneity of the effect on women's health outcomes. RESULTS: LTCI statistically significant increased self-rated health and reduced depression in women and improved the health in women with different roles by increasing self-rated health in female recipients, reducing chronic diseases in female caregivers, and reducing depression in female non-recipients and female non-caregivers. There was a more pronounced improvement in health outcomes among women in the west and northeast and women in rural village. CONCLUSIONS: After the implementation of LTCI, health outcomes in female recipients, female caregivers, and female non-recipients and female non-caregivers were improved. LTCI' improvement on women's health outcomes was heterogeneous geographically and socially. Our findings highlight the importance of delivering differentiated health interventions for women with different roles in the implementation process of LTCI and minimizing women's health inequalities in geography and society.

Prevalence and characteristics of frailty in older adults in Japan: a cross-sectional study using data from the long-term care insurance system.

[Purpose] Owing to rapid population aging, prevention of frailty in older adults and minimizing the burden on the long-term care insurance system are priorities for the Japanese government. However, limited data are available regarding the prevalence and characteristics of frailty among older adults requiring support in Japan. In this study, we investigated the prevalence and characteristics of frailty in older adults requiring support in Japan. [Participants and Methods] The study included 695 new users of preventive long-term care services certified as "requiring support" between 2011 and 2019. In this cross-sectional investigation, we used data obtained from a community comprehensive support center. Frailty prevalence was assessed using the Kihon Checklist, followed by a χ2 test. Logistic regression analysis was performed to identify the characteristics (basic information and service type) associated with frailty. [Results] A significantly large percentage of robust/pre-frail participants (72.7%) belonged to urban areas, although we observed no significant difference in robust participants with regard to residence. Furthermore, we observed significant intergroup differences in age and orthopedic conditions. [Conclusion] It is important to encourage older adults to access the long-term care insurance system and seek support at an early stage.

Long-Term Care Insurance for Older Adults in Terms of Community Care in South Korea: Using the Framework Method.

This study aimed to analyze the long-term care insurance for older adults in South Korea in terms of community care. An analytical framework was designed for the study, focusing on comprehensiveness, adequacy, and integration. The findings suggest that Korean LTCI is significantly limited for the development of community care. First, in terms of comprehensiveness, the use of visiting nurses and the availability of short-stay services have been significantly reduced, and the supporting services for informal caregivers are at the beginning stage of their introduction. Second, in terms of adequacy, the quantity of benefits, such as three to four hours of care a day, are insufficient to meet older adults' substantial needs. Furthermore, the overall quality of home care services is low, particularly with regard to short-stay services and welfare equipment. Finally, in terms of integration, basic linkage of organizations has not been properly conducted in local areas, and there remains an absence of care managers in the LTCI system. To cope with these challenging issues, the following policy measures are suggested: the activation of rehabilitation services, the expansion of benefit quantities, the improvement of service quality, and the creation of organizational linkages through local authorities and long-term care centers.

Last year of life care transitions between long-term care insurance services in Japan: Analysis of long-term care insurance claims data.

AIM: We determined the number of care transitions in the year before death among older adults requiring long-term care (LTC) and those receiving public LTC insurance (LTCI) services in Japan, along with care transition pathways and factors associated with the number of care transitions. METHODS: This study used data from the Japanese LTCI claims, which store national information on certification of needed LTC and LTCI claims data. Services received in the year before death were classified as in-home, facility, mixture of in-home and facility, and not using LTCI services. The transition count is presented, and Sankey diagrams are produced to visualize care transition pathways. We used a multivariable analysis to identify factors associated with the number of care transitions. RESULTS: Of the participants, 276 896 (65.2%) experienced at least one transition in LTCI care settings in the year before death. Further, 72.0% of those requiring mild LTC underwent one or more transitions. Participants who were 75-84 years old (vs. 65-74 years old), male, without medical care needs, with symptoms of dementia, and with changes in LTC needs in the year before death were more likely to require care transitions. Moreover, participants with higher baseline LTC needs were less likely to require transitions. CONCLUSION: Over half the participants requiring LTC underwent one or more care transitions in the year before death. Policy deliberations regarding enhancing care under the LTCI system at the end of life and optimizing care transitions are necessary. Geriatr Gerontol Int 2024; ••: ••-••.

Addressing healthy aging in China: Practices and prospects.

One important challenge for global development is aging. China is one of the world's countries with the highest elderly population and the most rapid aging; in 2022, the percentage of the population over 65 was 14.9%; by 2050, it is expected to rise to 26.1%. China's health security, elderly care, and healthcare services are facing serious challenges as a result of this aging trend. With 80% of provinces including medical and elderly care in national basic public health care programs, China has adopted a proactive national plan to combat population aging. Moreover, geriatric departments have been established at 69.3% of public general hospitals at secondary and higher tiers, 48% of provinces have devises preventive interventions for disability and dementia in the elderly, 48 percent of provinces are serving as test regions for medical care related to rehabilitation, and 49 cities are involved in long-term care insurance (LTCI) trials that encompass 170 million people. There are 4,259 medical and health care facilities that provide hospice care services, 152 hospice care pilot regions, and 87,000 pairs of contracts between medical and health care facilities and elderly care providers. These developments provide a strong basis, but there are still major obstacles to overcome. The Chinese Government is urged to adopt early preventive measures, offer more ongoing, practical, and cost-effective diagnostic and treatment services, allocate resources equitably, and use intelligent technologies to enhance elderly care. The ultimate goals are to lessen the financial burden, enhance the health of the elderly, and offer a vital global resource.

Long-term care insurance in Italy: medico-legal and socio-economic profiles.

Long-term care insurance (LTCI) plays a crucial role in providing substantial aid in non-self-sufficient situations and complementing existing state protection mechanisms. With an aging population and increasing demand for healthcare services LTC policies have become indispensable. While individual LTCI policies face adoption challenges, group insurances offer a more streamlined alternative. However, realizing the full potential of these insurances necessitates targeted legislative intervention to improve accessibility and ensure sustainability. This article explores the evolution of LTCI policies in Italy, offering an overview of the current landscape and highlighting the socio-economic and medico-legal factors shaping the present scenario. By providing this analysis, we seek to offer insights into the dynamic evolution of LTCI policies and the crucial role of legislative measures in enhancing their effectiveness and accessibility.

Long-run consequences of informal elderly care and implications of public long-term care insurance.

We estimate a dynamic structural model of labor supply, retirement, and informal caregiving to study short and long-term costs of informal caregiving in Germany. Incorporating labor market frictions and the German tax and benefit system, we find that in the absence of Germany's public long-term insurance scheme, informal elderly care has adverse and persistent effects on labor market outcomes and, thus, negatively affects lifetime earnings and future pension benefits. These consequences of caregiving are heterogeneous and depend on age, previous earnings, and institutional regulations. Policy simulations suggest that while public long-term care insurance policies are fiscally costly and induce negative labor market effects, they can largely offset the personal costs of caregiving and increase welfare, especially for low-income individuals.

Does income matter for the policy effect of public long-term care insurance on informal care use in China? A quasi-experimental study.

OBJECTIVE: Since 2016, the Chinese government has been piloting a public long-term care insurance (LTCI) scheme. This study examined whether the LTCI scheme reduced the use of informal care and how this has varied across income groups. METHOD: We used data from the 2011, 2014, and 2018 waves of Chinese Longitudinal Healthy Longevity Survey, focusing on community-dwelling older adults aged 65 years and older. We used staggered difference-in-differences analyses with propensity score matching to examine the effects of the policy. RESULTS: The LTCI scheme reduced the probability and intensity of informal care use by 5.7% (p < .05) and 17.4% (p < .05), respectively. The policy impact was limited to older people in the middle-income group, reducing the probability and intensity of informal care use by 15.6% (p < .001) and 43.1% (p < .05), respectively. We did not find a statistically significant policy effect for older adults with high or low incomes. CONCLUSIONS: The LTCI scheme had different effects on reducing the informal care burden for family caregivers by income level. We suggest that the scheme should entitle people with low incomes to a preferential co-payment rate, thereby enhancing their access to formal care.

Gendered Trends in Formal and Informal Care Utilization Among Older Adults in South Korea.

Drawing on data from two waves of the Korean Longitudinal Study of Ageing (2010 and 2018), this study examined how community-dwelling older men and women (65+) with functional limitations utilized formal and informal sources of care and how their patterns of care utilization changed over time. The usage patterns of formal and informal caregiving services were categorized into three groups: (a) informal help only, (b) formal-informal mix, and (c) no help from either. More men and women used both formal and informal help for their care needs in 2018 than in 2010 (15% compared to 7%). The proportion of older men who relied on informal help only remained similar across survey years, whereas a smaller proportion of older women relied on informal help only in 2018. Although formal care use has been expanded in South Korea, older men continue to utilize help from their families. However, for older women, the proportion who did not receive any help increased - despite an increase in formal care utilization. These findings highlight the importance of considering gendered resources in caregiving in Korea.

Effect of long-term care insurance policy on depression in non-disabled people: evidence from China.

BACKGROUND: Policy effect might be multidimensional and spill over to non-recipients. It is unclear how the implementation of Long-Term Care Insurance (LTCI) policy affects depression in non-disabled people and how this effect differs in different non-disabled groups. METHODS: Using time-varying differences-in-differences method and nationally representative health survey data in wave 2011, wave 2013, wave 2015 and wave 2018 from the China Health and Retirement Longitudinal Study, we assessed the effect of LTCI policy on depression in non-disabled people aged 45 years and older, and discussed the heterogeneity of effect across different population characteristics: retirement, financial support and social participation status. RESULTS: We found LTCI policy statistically significant reduced depression by 0.76 units in non-disabled people compared to non-pilot cities. Depression in non-disabled people who unretired, with financial support and without social participation was reduced by 0.8267, 0.7079 and 1.2161 units, respectively. CONCLUSIONS: Depression in non-disabled people was statistically significant reduced because of LTCI policy in China, and non-disabled people who unretired, with financial support and without social participation benefited more from LTCI policy. Our findings highlight the depression-reducing effect of LTCI policy in non-recipients and suggest that non-disabled people who unretired, with financial support and without social participation should be concerned during LTCI policy progress.

Long-term care needs and hospitalization costs with long-term care insurance: a mixed-sectional study.

Background: With the rapid aging of the population, the health needs of the older adult have increased significantly, resulting in the frequent occurrence of the "social hospitalization" problem, which has led to a rapid increase in hospitalization costs. This study investigates whether the "social hospitalization problem" arising from the long-term care needs can be solved through the implementation of long-term care insurance, thereby improving the overall health of the older adults and controlling the unreasonable increase in hospitalization costs. Methods: The entropy theory was used as a conceptual model, based on data from the China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018. The least-squares method was used to examine the relationship between long-term care needs and hospitalization costs, and the role that long-term care insurance implementation plays in its path of influence. Results: The results of this study indicated that long-term care needs would increase hospitalization cost, which remained stable after a series of tests, such as replacing the core explanatory variables and introducing fixed effects. Through the intermediary effect test and mediated adjustment effect test, we found the action path of long-term care needs on hospitalization costs. Long-term care needs increases hospitalization costs through more hospitalizations. Long-term care insurance reduces hospitalization costs. Its specific action path makes long-term care insurance reduce hospitalization costs through a negative adjustment of the number of hospitalizations. Conclusion: To achieve fair and sustainable development of long-term care insurance, the following points should be achieved: First, long-term care insurance should consider the prevention in advance and expand the scope of participation and coverage; Second, long-term care insurance should consider the control in the event and set moderate levels of treatment payments; Third, long-term care insurance should consider post-supervision and explore appropriate payment methods.

Evaluation of China's long-term care insurance policies.

Introduction: In response to the increasing demand for long-term care services for older people, the Chinese government has launched a pilot program for long-term care insurance (LTCI) since 2016. The objective of this study is to evaluate the performance and effectiveness of this program in China and provide recommendations for the future development and expansion of the LTCI system. Methods: We developed a comprehensive evaluation framework to assess these LTCI policies implemented in all 49 pilot cities in China. Results: Based on our evaluation, the average assessment score for the LTCI program across all pilot cities was 71.8 points, with scores ranging from 57.5 to 92.5 points in these cities. Furthermore, most of the pilot cities achieved higher scores in the fact-based assessment compared to the value-based assessment. Discussion: The results suggested that the overall pilot effect regarding LTCI was favorable, but there were significant regional disparities. Moreover, in most of pilot cities, current LTCI policies were designed to alleviate both the financial burden and the burden of caring for people with disabilities that families faced. However, some challenges still remained, such as the lack of community and home-based care services, the need to expand the coverage of insurance, and the importance of diversifying funding sources.
