Companion animals have recently been proposed as ideal translational models of human aging due to their shared susceptibility for certain diseases, similar environments, and sophisticated veterinary medicine diagnostics, all of which are not possible in rodent laboratory models. Here, we introduce and propose the study of companion animals in China as a largely untapped resource in academic and veterinary aging research. Pet ownership rates along with economic gains in the pet industry have skyrocketed over the last decade in China. Yet, the majority of research institutions still focus on agricultural animal research, not companion animals. In this perspective, we compare available pet ownership rates between the USA, the European Union, and China before focusing on the potential of companion animal aging research in China. In addition, we highlight some ethical considerations that must be addressed before large-scale companion animal aging research can be completed., (© 2021. The Author(s).)

With the introduction of the New Rural Social Pension Scheme (NRSPS), pension coverage in rural China has increased substantially during the last decade. We investigate how the new public pension benefits influence intergenerational transfers and subjective well-being of older adults in rural China using panel data from the 2011 and 2013 waves of the China Health and Retirement Longitudinal Study (CHARLS). The results of our first-difference regression models show that receiving a public pension goes along with an increase in intergenerational financial support and has a positive impact on the subjective well-being of older adults in rural China. Our analysis represents one of the first studies examining the effects of the introduction of the NRSPS from a longitudinal perspective. The results demonstrate that public pension benefits as a form of institutional financial support are beneficial to the well-being of older adults, while they do not hinder intergenerational exchange.

Conventionally, the 2-parameter Weibull model, Arrhenius-Weibull model, has been used vastly for transformer aging-dependent unavailability modeling. However, this model only uses the lifetime feature to describe the transformer's degradation process and to calibrate the Weibull parameters, which harms the accuracy of aging-dependent unavailability forecasting. In response, this paper develops a 3-calibratable-parameter Weibull model for evaluating the transformer aging-dependent unavailability. In the proposed model, both the individualized aging threshold and lifetime are taken into the calibration of the Weibull parameters to accurately characterize the heterogeneity in transformer populations. First, a degree of polymerization (DP) analysis and Monte Carlo Simulation (MCS) based approach is proposed for estimating the transformers’ uncertain aging thresholds and lifetimes. Then, the Maximum Likelihood Estimate and Particle Swarm Optimization are jointly adopted to model the relationship among the calibratable Weibull parameters, aging threshold, and lifetime. Finally, the analytical formula of aging-dependent unavailability is derived from the established 3-calibratable-parameter Weibull model using an integral-discretization method. A real utility application example in China's Chongqing power system has been presented to validate and demonstrate the practicality and usefulness of this method. [ABSTRACT FROM AUTHOR]

This paper examines the influence of consumers' gender and age on the relationship between their attitudes and purchase intentions for choosing a sustainable retirement village, drawing on the Ecological Theory of Aging and the Theory of Reasoned Goal Pursuit. About 931 research participants were collected in China through an online research firm, which distributed questionnaires to its sampling database. Partial Least Squares Structural Equation Modeling was employed to test the proposed hypotheses. The study reveals that (1) consumers' attitudes toward sustainable retirement villages mediate the relationship between social and environmental sustainability and purchase intentions; (2) The link between the attributes of sustainable retirement villages and consumers' purchase intentions is mediated by their attitudes, which are not influenced by the consumers' gender or age. This research demonstrates that neither the gender nor age of consumers significantly impact their attitudes and purchase intentions regarding sustainable retirement villages. The scope of this study is constrained by its sample and variables, as the research subject focuses specifically on Chinese consumers' attitudes and intentions toward sustainable retirement villages.

This study explores the role of family and community support in promoting active aging among the elderly in China, utilizing data from the seventh wave of the Chinese Longitudinal Healthy Longevity Survey. We analyzed how family support and psychological resilience contribute to active aging. Our findings indicate that while general family support shows a negative correlation with psychological resilience and active aging, emotional support from the family positively influences both. Additionally, psychological resilience is a partial mediator in this relationship, with community support as a moderator. The results suggest that interventions to increase emotional support from family and community could significantly enhance active aging., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Introduction: A standardized measure for inflammaging is lacking. We introduced the inflammatory age (iAge) as a quantification method and explored its associations with age-related traits and diseases in an older Chinese cohort., Methods: Inflammatory markers including white blood cell count (WBC), neutrophils, lymphocytes, monocytes, C-reactive protein, platelets and albumin were measured. Quantitative real-time polymerase chain reaction was used to measure telomere length. Traditional multivariable linear, partial least squares, and logistic regression were used., Results: iAge was constructed based on WBC, neutrophils, monocytes and albumin, which were associated with telomere length independently. A higher iAge indicated a heavier aging-related inflammation burden. Per 1-year increase in iAge was associated with higher body mass index (β 0.86 (95 % CI 0.67, 1.05) kg/m 2 ), waist circumference (β 2.37 (95 % CI 1.85, 2.90) cm), glycosylated hemoglobin A 1c (β 0.06 (95 % CI 0.02, 0.10) %), systolic blood pressure (β 1.06 (95 % CI 0.10, 2.03) mmHg), triglycerides (β 0.05 (95 % CI 0.01, 0.08) mmol/L), 10-year cardiovascular diseases risk (β 0.05 (95 % CI 0.02, 0.08) %), diabetes (OR 1.22 (95 % CI 1.02, 1.46)), hypertension (OR 1.21 (95 % CI 1.04, 1.42)) and metabolic syndrome risks (OR 1.25 (95 % CI 1.04, 1.51)), and lower fasting plasma glucose (β -0.016 (95 % CI -0.024, -0.007) mmol/L), total cholesterol (β -0.06 (95 % CI -0.12, -0.01) mmol/L) and high-density lipoprotein cholesterol (β -0.05 (95 % CI -0.07, -0.03) mmol/L)., Conclusion: The newly introduced iAge, derived from inflammatory markers and telomere length, aligns with various metabolic dysfunctions and age-related disease risks, underscoring its potential ability in identifying aging-related phenotypes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Income increase is an important way to achieve comprehensive human development and to escape from poverty, and the growing aging problem in rural China poses a challenge to farm household income increase. In order to gain a deeper understanding of the impact of China's rural old-age burden on farm household income, this paper empirically examines the impact and mechanism of household old-age burden on farm household income based on the data from the 2023 micro-farm field survey of China's Henan Province, utilizing linear regression modeling and mediation effect modeling, filling the research gaps in the related fields. The results of the study found that, firstly, family old-age burden has a significant impact on the income of farm households, and that the heavier the family old-age burden, the lower the total income of farm households. Secondly, from the results of the heterogeneity of the impact, the poorer the health condition, the greater the negative impact of family old-age burden on farm household income. Old-age burden has a greater impact on high-income farm households than on low-income farm households, and old-age burden has a significant impact on the income of part-time farm households, while the impact is not significant on purely farm and non-farm households. Thirdly, the heavier the household old-age burden, the more unfavorable it is to the non-farm employment of farm households, thus affecting the income capacity of farm households. Finally, corresponding countermeasures and recommendations are put forward in three areas, namely, the continuous improvement of the social old-age security system, the realization of the function of the social old-age mechanism as an old-age pocket for key special groups, and the improvement of the social flexible employment mechanism.

Exploring the adoption intention of smart senior care services can help improve the actual adoption rate. Taking a questionnaire survey of 1600 households in Anhui Province as an example, structural equation modeling was used to study the adoption intention and influencing factors of smart senior care services. The results show that subjective norms, perceived usefulness and perceived ease of use are the key factors influencing the adoption intention of smart senior care services. Further, age has an impact on perceived usefulness and adoption intention, education has an impact on perceived ease of use and adoption intention, and monthly household income has an impact on perceived usefulness and adoption intention. This paper broadens the existing technology acceptance model (TAM) theory and provides some basis for the development of economics. The findings will be beneficial to the government in formulating more precise policies on elderly services to properly address the challenges of aging. [ABSTRACT FROM AUTHOR]

Although a number researchers have acknowledged that the aging population inhibits firm digital transformation, others find it promoting digital transformation in some firms. As the relevant literature to clarify such paradox is still scare, this paper wants to fill the gap regarding the labor cost theory, the capital-skill complementarity hypothesis, and the human capital externality theory. Based on the empirical tests of Chinese A-share listed companies from 2001 to 2022, this study detected a U-shaped relationship between the aging population and digital transformation. In terms of the institutional environment, higher marketization strengthens the U-shaped relationship by making the slopes on either side of it steeper. However, higher minimum wage levels weaken the U-shaped relationship. In terms of firm strategy, firms with stronger marketing capabilities strengthened the U-shaped relationship. However, firms with higher customer concentration weakened the U-shaped relationship. Overall, we enriched scholarly understanding of the impact of the aging population on digital transformation and demonstrated the dual potential impact of aging populations. Instead of assuming they are detrimental to the economy and society, positive contributions in the form of innovation and progress for companies can be detected., (© 2024. The Author(s).)

Background: In China, the healthcare financing structure involves multiple parties, including the government, society and individuals. Medicare Fund is an important way for the Government and society to reduce the burden of individual medical costs. However, with the aging of the population, the demand of Medicare Fund is increasing. Therefore, it is necessary to explore the sustainability of the healthcare financing structure in the context of population ageing. Objective: The purpose of this paper is to organize the characteristics of population ageing as well as healthcare financing in China. On this basis, it analyzes the impact mechanism of population ageing on healthcare financing and the sustainability of existing healthcare financing. Methods: This paper mainly adopts the method of literature research and inductive summarization. Extracting data from Health Statistics Yearbook of China and Labor and Social Security Statistics Yearbook of China. Collected about 60 pieces of relevant literature at home and abroad. Results: China has already entered a deeply ageing society. Unlike developed countries in the world, China's population ageing has distinctive feature of ageing before being rich. A healthcare financing scheme established by China, composing of the government, society, and individuals, is reasonable. However, under the pressure of population ageing, China's current healthcare financing scheme will face enormous challenges. Scholars are generally pessimistic about the sustainability of China's healthcare financing scheme. Conclusions: Population ageing will increase the expenditure and reduce the income of the Medicare Fund. This will further affect the sustainability of the healthcare financing structure. As a consequence, the state should pay particular attention to this issue and take action to ensure that the Fund continues to operate steadily. [ABSTRACT FROM AUTHOR]

The Chinese government implemented the universal two-child policy on January 1, 2016 to arrest the decline in the nation's birthrate and address the challenge of a rapidly aging population. We find that this policy significantly increased the possibility of having children and this effect was not attenuated from 2016 to 2018. This policy can explain 14.8% of the average number of newborns in 2016-2018. Our back-of-the-envelope calculation suggests that the three-child policy implemented in 2021 will bring additional 283.2 thousand newborns each year. [ABSTRACT FROM AUTHOR]

This paper documents the patterns and correlates of retirement in China using a nationally representative survey, the China Health and Retirement Longitudinal Study. After documenting stark differences in retirement ages between urban and rural residents, the paper shows that China's urban residents retire earlier than workers in many Organization for Economic Co-operation and Development countries and that rural residents continue to work until advanced ages. Differences in access to generous pensions and economic resources explain much of the urban–rural difference in retirement rates. The paper suggests that reducing disincentives created by China's Urban Employee Pension system, improving health status, providing childcare and elder care support may all facilitate longer working lives. Given spouse preferences for joint retirement, creating incentives for women to retire later may facilitate longer working lives for both men and women. [ABSTRACT FROM AUTHOR]

In China, the number of senior citizens has grown, along with the burden of old age, and aging has hampered economic growth. The advent of the digital age has led to the emergence of the digital economy as a new engine for economic growth. This paper uses DEA-Malmquist index model to measure the total factor productivity growth rate of 31 provinces in China from 2011 to 2021, and uses the moderating effects model to empirically investigate the relationship between the digital economy, aging and total factor productivity, and to verify whether the development of the digital economy can mitigate the negative impact of aging on total factor productivity. The results show that aging inhibits total factor productivity growth, and the digital economy can promote total factor productivity growth. Digital economy can alleviate the negative impact of aging on total factor productivity growth, and has a moderating effect. Digital economy plays a moderating role by improving the level of human capital and facilitating technological progress. The regional heterogeneity analysis shows that the moderating effect of the digital economy exists in the eastern and western regions and the southern region, but not in the central region and the northern region. Furthermore, the digital economy has a moderating effect on both the high and low aging groups. The research in this paper not only helps to evaluate the productivity effects of the digital economy, but also has important implications for finding ways to mitigate the negative effects of aging., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Meng, Wen.

Background and Objectives: Aging poses a significant challenge worldwide, with China's aging status becoming particularly severe. What is the impact of Internet use on the health of the elderly? Existing studies have drawn conflicting conclusions that Internet use improves or harms health. The purpose of this study was to explore how Internet use affects the health of older adults, and the mechanisms and heterogeneity of these effects., Research Design and Methods: Based on Grossman's theory, this paper constructs a health production function model. Using the data of China Family Panel Studies (CFPS) from 2014 to 2020, we investigated the impact of Internet use on the health of older adults using fixed effect model and instrumental variable method. We also examined the mediating role of health information acquisition, lifestyle, and social interaction in these associations., Results: Internet use is positively associated with self-rated health and negatively associated with psychological sub-health level. Internet use promotes the health of older adults by facilitating access to health information, healthy lifestyles, and enhancing social interaction. And the impacts are heterogeneous at the individual and regional levels., Discussion and Implications: We should progressively enhance the level of internet accessibility for older adults, while concurrently addressing and narrowing the 'digital divide'. By generating an abundance of superior health-related information, we can significantly improve health education tailored for the elderly. Additionally, it is crucial to offer extensive training opportunities designed to equip older adults with the necessary skills to proficiently navigate the internet., (© 2024. The Author(s).)

Background: With the intensification of China's aging population, the demand for elderly care services has become increasingly prominent. At the same time, rapid development of internet technology provides more convenience and possibilities for the elderly. However, the coordinated development between the internet and elderly care services still faces challenges. This study aims to measure the level of coupling and coordinated development between the internet and elderly care services in China, and analyze the influencing factors, in order to provide reference for promoting elderly care services., Methods: In this paper, the entropy method and coupling coordination degree model were used to measure the coupling coordination development index of the internet and elderly care services in China from 2012 to 2021. In addition, considering that the coordinated development between the two is affected by many factors, the Tobit model was used to analyze the main factors affecting the integration of the internet and elderly care services., Results: (1) The coupling and coordination of the Internet and senior care services is in its infancy, but the coupling and coordination of the two is on the rise, and there is still a lot of room for development in the future. (2) In terms of time scale, the coupling coordination development level between the internet and elderly care services in China has gone through three stages of "disorder recession-transition coordination-coordinated development". (3) In terms of influencing factors, government management ability has a more positive impact on the development of the integration of the Internet and senior care services, financial support, scientific and technological investment and the level of innovation play a mild pulling role, while the level of informatization to a certain extent restricts the level of integration of the Internet and senior care services., Conclusion: In order to promote the coordinated development of China's Internet and senior care services, it is necessary to comprehensively understand the current situation and development space of China's Internet and senior care services coupling coordination degree, accurately grasp the dynamic trend of China's Internet and senior care services coupling and coordinated development, promote the stage of leapfrogging, and fully consider the influencing factors, so as to realize the optimal allocation of policies and resources. These measures will help to promote a more coordinated and sustainable development of the internet and elderly care services in China., (© 2024. The Author(s).)

High carbon emissions and population aging are two obstacles to China's development as an emerging economy. It is urgent to scientifically examine the impacts of population aging on carbon emissions to discover new pathways for urban carbon emission reduction. However, existing studies face challenges in terms of focusing on and methodology for accurately capturing the role of industrial production and energy consumption in the environmental effects of population aging. This paper constructs a chain mediation analytical framework and systematically examines the intrinsic linkages between population aging and carbon emissions in Chinese cities from 2000 to 2020 using a two-way fixed effects model. This paper has three main findings. (1) The positive correlation between urban population aging and carbon emissions development is generally low, with coupling coordination degree values of 0.4233, 0.4458, 0.4220, 0.4715, and 0.4665 for each yearly cross-section. (2) For every 1% increase in the population aging rate, carbon emissions decrease by 0.3478% on average. The carbon reduction effect of population aging is significantly greater in low-emissions cities and high-income cities than in other cities. (3) The industrial upgrading (IU) path, energy conservation (EC) path and chain mediation (CM) path account for 72.43%, 7.23% and 20.34%, respectively, of the indirect effects. If the causal link between IU and EC is not considered, the EC effect will be overestimated by 281.16%. The results of the study suggest that properly coping with population aging and reducing carbon emissions are not completely opposed to each other, a conclusion that passes both endogeneity exclusion and robustness check. This paper advocates replacing the one-size-fits-all approach in carbon emissions management and investing more in policy preferences to support carbon emission reduction in both high-emissions and low-income cities., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Considering data from the fourth wave of the China Family Panel Studies (CFPS2016), this paper examines the impact of mobile Internet usage on the relationship between adult children and elderly parents. Results drawn from ordered Probit and mediation models show that mobile Internet use, rather than the usage of the fixed Internet, enhances the parent–child relationship. Secondly, older parents, having two or more children, cannot benefit well from using the mobile Internet, and they may rely more on phone calls to uphold intergenerational contact. Thirdly, the mobile Internet enhances the non-face-to-face contact between the two generations. Also, it reduces face-to-face contact in child–parent relationships and improves face-to-face contact in the parent–child relationship. Therefore, related to increasing in the population aging, relevant departments should continue to enhance the use of mobile Internet by reducing the usage costs, improving the usage capabilities, and innovating mobile phone functions, and remain cautious due to the reduction in face-to-face communication caused by the mobile Internet use.

In the context of the deepening of population aging and the trial implementation of a progressive retirement delay policy in China, understanding the relationship between the labor force participation and health status of the elderly will not only enrich relevant research but also help the elderly better achieve their goals of active aging and aging. Using the 2018 China Health and Retirement Longitudinal Study, this paper first established multiple linear regression models to analyze the impact of labor force participation on the health status of elderly people in China and then established simultaneous equation models using households living on minimum living allowances and the community average of labor participation as instrumental variables to deal with the endogeneity caused by two-way causality. The findings confirmed significant positive correlations between labor force participation and physical and mental health, while caring for grandchildren and participating in social activities were found to be negatively moderated the relationship between labor force participation and the physical and mental health of older adults. The impact of labor force participation on the physical health status of older men and the mental health status of older women may be greater. In addition, labor force participation may have a greater impact on the physical health of the rural elderly, and its impact on mental health was not found to be statistically significant between urban and rural areas.

Background: The ageing of the population has become an escalating problem in China, which has led to an increasing demand for healthcare throughout society. The care services of elderly institutions, as a more mature way of aging, can alleviate various social problems brought about by ageing to a certain extent. The aim of this paper is to explore the degree of acceptance of institutional care by rural elderly people in Shandong Province and the factors that influence whether rural elderly people accept institutional care services., Methodology: Based on the theory of planned behavior, an analytical framework was constructed for the willingness of rural elderly people to receive nursing services from elderly care institutions. Using survey data from 192 rural elderly people in Shandong Province, descriptive statistics, binary logistic regression, and horizontal comparative analysis methods were used to analyze the willingness of rural elderly people to provide for the elderly and its influencing factors., Result: Only 17.71% of respondents expressed willingness to receive services from elderly care institutions. Among them, education level, trust in elderly care institutions, and support from adult children have a significant positive impact on whether rural elderly people receive nursing services from elderly care institutions; The number of children, the level of understanding of elderly care institutions, neighbors' choices of elderly care methods, and their ability to contribute to the family have a significant negative impact on whether rural elderly people receive nursing services from elderly care institutions. There are significant differences in the willingness and influencing factors of rural elderly people to provide for the elderly among different regions., Conclusion: The non-acceptance of institutional care by rural older people is a general phenomenon rather than a sample characteristic, thus justifying the supplementary status of institutional care services. The pension intention of the rural elderly in Shandong Province is obviously affected by personal will factors, and the influencing factors are various. The traditional concept of old-age care in Shandong province has a strong path-dependent effect on the choice of the rural elderly. There is heterogeneity in the willingness and influencing factors of the rural elderly in different regions and countries. Based on this, this paper puts forward the following suggestions: strengthen the spiritual and cultural construction of residents; The government should pay attention to the correct guidance of public opinion; And increase pension subsidies. It is hoped that reduce the burden of national elderly care through these suggestions., (© 2023. The Author(s).)

Population aging and carbon emissions are critical issues for China's development. As an enormous complex system, the population and the carbon emission development process have non-negligible differences in time, space, and speed. Therefore, this paper first demonstrates the spatial and temporal correlation between population aging and carbon emissions from 1995 to 2020, then uses the allometric growth analysis model to make a cross-sectional temporal comparison and a vertical spatial comparison of the relationship and development rate of the two, and finally uses the ridge regression model to determine the forces and interaction mechanisms of the factors influencing the relationship between population aging and carbon emissions at allometric rates. The results show that (1) China has a long-term positive temporal correlation effect relationship between population aging and carbon emissions from 1995 to 2020, and the overall correlation is high. The spatial correlation intensity between population aging and carbon emissions varies significantly across Chinese provinces, with a general spatial distribution trend of high in the south, low in the north, and prominent in the center. (2) China's population aging and carbon emissions mainly show a negative allometric growth type of relationship, i.e., a strong trend of population aging expansion and a strengthening trend of carbon emission system shrinking. The number of provinces with negative allometric growth is gradually increasing, mainly in North, East, Central, and Southwest China. (3) From 1995-2010 period to the 2011-2020 period, the influence of the factors of the population, production, and economic dimensions on the population aging index and the carbon emission allometric scalar index gradually weakened, and the influence of the consumption and technology dimensions increased significantly. The factors on the population and consumption side of the dimension mainly contribute to the expansion of carbon emissions and drive positive allometric growth. The production side, the economic structure, and technology dimension factors drive negative allometric growth. The paper fully explores the bidirectional correlation, differential development trend, and interaction mechanism between the two systems of population and carbon emissions and effectively compensates for the lack of research content in terms of elemental correlation, spatial and temporal connection, and speed synergy., (© 2023.

China's population is showing the characteristics of "fewer children" and "aging", which will have a long-term and far-reaching impact on the food and nutritional needs of China and the world. In this paper, adult equivalent scale ( AES ) variables representing the household population structure were introduced into the energy intake model to quantify the impact of population structure changes on energy intake and reveal the characteristics of energy intake changes in the life cycle of Chinese residents. It is found that the change in the population structure has a significant impact on the energy intake of urban households in China, and the elasticity is 0.446. The energy intake of Chinese elderly over the age of 60 shows a trend of first increasing and then decreasing, especially after the age of 65, which indicates that the aging will promote a decline in food consumption in China. The energy intake of 1-10-year-old children, 22-30 year old, and 40-45 year old women all showed a change of first a decrease and then an increase, which may be related to parents' care for young children and women with children's management of body size. The average household size expressed by the adult equivalent scales of energy consumption is 2.341, which is smaller than the 3.052 calculated by the population number. The conclusion indicates that the prediction of the food and nutritional demand should be adjusted according to the changes and differences in accordance with the intensification of "fewer children" and "aging", as well as the life cycle changes in residents' energy intake, which is conducive to the formulation of food and nutrition security policies.

Background: Presently, global aging has become increasingly serious, whereas the health concerns brought by aging have become a public issue that warrants an urgent solution from all countries across the world. Therefore, this research paper discusses the influence of neighborhood health on elderly individuals' health, and extending a realistic basis for the other economies to improve the neighborhood environment and promote the health of the elderly., Methods: Based on the data of CHARLS2018, this research paper adopts the samples that fulfill the study requirements (N = 7326). we constructed a comprehensive research framework integrating oprobit regression model, heterogeneity analysis, conditional mixed process(CMP)robustness testing, Furthermore, the KHB decomposition method is implemented to ascertain the influential mechanism of NMH and NPH on the mental- and physical health of elderly persons., Results: The oprobit regression model analysis indicates that NMH 0.434 and NPH 0.550 exert positive influences on the elderly's mental- and physical health. Meanwhile, the effects of conditional mixed process on NMH and NPH stand at 0.381 and4.372, which are different from the oprobit regression results; thereby, indicating the existence of endogeneity. Afterward, KHB mediating effect confirms that Internet use, gift reciprocity, and charity activity contribute 30.21% and 16.83% to mental- and physical health, respectively., Conclusions: Firstly, the NMH and NPH demonstrate a positive influence on the mental- and physical health of the elder population. However, there exist heterogeneous differences. Secondly, the conditional mixed process deals with the endogeneity of NMH and NPH. Thirdly, social integration, social interaction, and social engagement serve as significant transmission mechanisms for the influences of NMH and NPH on the health of elderly persons., (© 2023.

Background: Mild cognitive impairment (MCI) is commonly defined as a transitional subclinical state between normal aging and dementia. A growing body of research indicates that health behaviors may play a protective role against cognitive decline and could potentially slow down the progression from MCI to dementia. The aim of this study is to conduct a bibliometric analysis of literature focusing on health behaviors and MCI to summarize the factors and evidence regarding the influence of health behaviors on MCI. Methods: The study performed a bibliometric analysis by retrieving publications from the Science Citation Index and Social Sciences Citation Index subdatabases within the Web of Science Core Collection. Utilizing VOSviewer and CiteSpace software, a total of 2,843 eligible articles underwent co-citation, cokeywords, and clustering analyses. This methodology aimed to investigate the current status, trends, major research questions, and potential future directions within the research domain. Results: The bibliometric analysis indicates that research on healthy behaviors in individuals with MCI originated in 2002 and experienced rapid growth in 2014, reflecting the increasing global interest in this area. The United States emerged as the primary contributor, accounting for more than one-third of the total scientific output with 982 articles. Journals that published the most articles on MCI-related health behaviors included "Journal of Alzheimer's Disease," "Neurobiology of Aging," "Frontiers in Aging Neuroscience," and other geriatricsrelated journals. High-impact papers identified by VOSviewer predominantly cover concepts related to MCI, such as diagnostic criteria, assessment, and multifactorial interventions. Co-occurrence keyword analysis highlights five research hotspots in health behavior associated with MCI: exercise, diet, risk factors and preventive measures for dementia, cognitive decline-related biomarkers, and clinical trials. Conclusion: This study provides a comprehensive review of literature on health behavior in individuals with MCI, emphasizing influential documents and journals. It outlines research trends and key focal points, offering valuable insights for researchers to comprehend significant contributions and steer future studies. [ABSTRACT FROM AUTHOR]

In this paper, we investigate the heterogeneous treatment effects of retirement on the mental health of older adults using the generalized random forest (GRF) method. GRF has high functional flexibility and can explore complex treatment heterogeneity by selecting covariates from high-dimensional data that contribute to heterogeneity. Results show that retirement significantly reduces the elderly group's depression as well as increases subjective well-being, implying that it will improve mental health. The best linear predictor test suggests that the effect of retirement on depression is heterogeneous among the data for 2014 and 2020 but not in the analysis of well-being. Retirement is more effective in improving depression for males who are at an unhealthy weight, are between the ages of 57 and 67, and have an Internet habit. The results of this paper provide support for promoting the optimization and individualized implementation of relevant policies and improving the lives of the elderly in their later years.

Aims: The purpose of this study was to identify risk factors for cognitive impairment in advanced cancer patients and to develop predictive models based on these risk factors. Background: Cancer‐related cognitive impairment seriously affects the quality of life of advanced cancer patients. However, neural network models of cognitive impairment in patients with advanced cancer have not yet been identified. Design: A cross‐sectional design was used. Methods: This study collected 494 questionnaires between January and June 2022. Statistically significant clinical indicators were selected by univariate analysis, and the artificial neural network model and logistic regression model were used for multivariate analysis. The predicted value of the model was estimated using the area under the subject's working characteristic curve. Result: The artificial neural network and the logistic regression models suggested that cancer course, anxiety and age were the major risk factors for cognitive impairment in advanced cancer patients. All the indexes of artificial neural network model constructed in this study are better than those of the logistic model. Conclusion: The artificial neural network model can better predict the risk factors of cognitive impairment in patients with advanced cancer. Better prediction will enable nurses and other healthcare professionals to provide better targeted and timely support. Summary statement: What is already known about this topic?: Cancer‐related cognitive impairment has significantly affected the quality of life of patients with advanced cancer.Risk factors associated with cognitive impairment in patients with advanced cancer have not been adequately documented, and neural network models have not been identified. What this paper adds?: This study found that long a cancer course, anxiety and ageing were the most important risk factors for cognitive impairment in patients with advanced cancer.The artificial neural network showed good predictive indicators, indicating that it can be used to predict cognitive impairment in patients with advanced cancer. The implications of this paper: Neural network models can help nurses and other clinicians predict cognitive impairment in advanced cancer patients early which will allow provision of timely intervention.

This paper studies the role played by the digitization level of inclusive finance for the aging population. We leverage an unexpected Chinese national strategy that promotes mobile internet and other internet related integration in China to identify the impact of changes in state policies on the digitization level for inclusive finance in a regression discontinuity design. Although aging population is negatively correlated with the digitization level of inclusive finance, our empirical analysis reveals that the policy shock significantly increased the digitization level of inclusive finance among the aging population. We also find two opposite mechanisms: the income effect and the caring effect. Finally, our study suggests that the economic and social outcomes of the digitization level among aging population are bifurcated: happiness decreased but real estate investment increased., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Zhou, Ye.

Background: Accurately predicting the future development trend of population aging is conducive to accelerating the development of the elderly care industry. This study constructed a combined optimization grey prediction model to predict the structure and density of elderly population., Methods: In this paper, a GT-FGM model is proposed, which combines Theta residual optimization with fractional-order accumulation operator. Fractional-order accumulation can effectively weaken the randomness of the original data sequence. Meanwhile, Theta residual optimization can adjust parameter by minimizing the mean absolute error. And the population statistics of Shanghai city from 2006 to 2020 were selected for prediction analysis. By comparing with the other traditional grey prediction methods, three representative error indexes (MAE, MAPE, RMSE) were conducting for error analysis., Results: Compared with the FGM model, GM (1,1) model, Verhulst model, Logistic model, SES and other classical prediction methods, the GT-FGM model shows significant forecasting advantages, and its multi-step rolling prediction accuracy is superior to other prediction methods. The results show that the elderly population density in nine districts in Shanghai will exceed 0.5 by 2030, among which Huangpu District has the highest elderly population density, reaching 0.6825. There has been a steady increase in the elderly population over the age of 60., Conclusions: The GT-FGM model can improve the prediction accuracy effectively. The elderly population in Shanghai shows a steady growth trend on the whole, and the differences between districts are obvious. The government should build a modern pension industry system according to the aging degree of the population in each region, and promote the balanced development of each region., (© 2023.

China is in a period of rapid population aging. The total population of the elderly aged 60 and above in mainland China was 264 million in 2020, and is the country with the largest elderly population in the world, which is home to 1/5 of the world's older people. The urgency of actively coping with the aging population has never been greater, and China has raised it to the height of national strategy. To this end, China has issued several plans and projects on aging work. Many of them include multiple overlapping components. The management of physical illness and mental illness in the elderly is over-differentiated and segmented. However, it is common for older adults with complex health problems. The body and mind are inherently integrated and interact with each other, and should not be separated. There is an urgent need for integrated healthcare services for the physical and mental health of the elderly population. The national basic public health services play an important role in early detection and awareness of health problems for the elderly in community health services. This paper introduces the elderly health management services, one of the national basic public health projects, and the psychological care project for the elderly in Shenzhen, Guangdong Province, China. Taking Long-gang District's exploration of the joint management of physical and mental health of the elderly as an example, this review discusses the difficulties of the elderly health work, and the feasibility of integrating the elderly mental health and physical health in medical care. We outlook to build an integrated platform for physical and mental health of the elderly in China. Focus on the needs of older population, strengthen community health services, build a integrative team, fully publicize and improve health literacy of the elderly, link up and down and work together, improve coordination between providers of medical care and social services. It is of great significance to construct a strong public health system for the elderly and promote the realization of the grand goal of Healthy China. [ABSTRACT FROM AUTHOR]

With the aggravation of population aging, the health of the elderly has become an important issue in the aging society. The Mediterranean diet (MD) contributes to healthy aging by changing dietary patterns to delay and prevent disease onset. This paper summarizes the concepts related to the MD pattern and its relationship with cardiovascular diseases, cognitive dysfunction, depression, chronic inflammation and other brain and heart comorbidity in the elderly, so as to provide thinking and reference for the optimization and upgrading of the elderly, and contribute to the development of healthy China.

This study investigates the gender disparities and cohort differences in the health trajectories of older Chinese adults. Drawn on a nationally representative dataset from the 2008–2018 Chinese Longitudinal Healthy Longevity Survey, this paper uses a growth-curve model to identify the health trajectories of older adults in functional limitations, chronic diseases, depressive symptoms and cognitive skills. Older women are found to have slightly fewer functional limitations than older men at an earlier age; however, this gap is reversed later because of women's higher deterioration rate in physical function. Compared to men, older women have more chronic diseases at younger ages, but this trend is changed after age 90 years due to a faster decline rate in chronic diseases for women. The gender gap in the depressive symptom trajectories narrows with age, whereas the gap in the trajectories of cognitive skills widens. The cohort differences favouring later-born cohorts decrease with age in the trajectory of functional limitations. The latest cohort born in 1940 or after has the fastest increase in chronic diseases and depressive symptoms among all the cohorts. These results are further verified using the random-effect model and pooled ordinary least squares. Policymakers should promote gender equality and reduce cohort differences to achieve the national goal of "Healthy China". [ABSTRACT FROM AUTHOR]

The steady increase in China's ageing population and an upswing in migration among the country's population, on the whole, has caused a continuous expansion of the scale of older migrants. The migration of older adults not only directly affects the well-being of individual families but also significantly impacts the population structure and economic development of the places of origin and destination. Despite this, in China, the various relevant aspects concerning this age group and, in particular, its migration choices and the patterns thereof have only rarely been the subject of sound research. The study presented in this paper seeks to fill this gap; the present study makes use of the microdata obtained from the national population censuses of 2000 and 2010 and the 1% population sample surveys conducted nationally in 2005 and 2015. The findings of the present study were the following: ① During 1995-2015, the efficiency of older adults' migration was significantly higher in the eastern region than in the central and western regions. ② Older individuals migrating to urban areas are increasingly choosing, for their relocation, economically developed, urban areas such as the Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Hebei region. ③ Relocation of older adults to urban areas was much more than to rural areas. The latter group has a more diverse choice of destination, and the larger migration flow is primarily from developed provinces to relatively underdeveloped provinces. ④ The results of binary logit regression indicated that the factors that significantly and consistently influence the migration decisions of older adults were found to be the following: age, education level, health status, the primary financial resource, children aged ≤ 6 years being members of the household that would receive the migrants, and the average wage of employees. As for the geographical characteristics of the province to which the older adults migrate, a substantial difference was observed between the preferences of older adults migrating to urban regions and those of older adults relocating to rural areas. The findings of the present study provide further insight into the decision-making of older adults regarding migration. Further, these findings constitute an empirical basis for the local governments concerned to devise and implement policies to better cope with an ageing population., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Wu, Wu.

Alzheimer's disease (AD) is the most common cause of dementia. Accurate prediction and diagnosis of AD and its prodromal stage, i.e., mild cognitive impairment (MCI), is essential for the possible delay and early treatment for the disease. In this paper, we adopt the data from the China Longitudinal Aging Study (CLAS), which was launched in 2011, and includes a joint effort of 15 institutions all over the country. Four thousand four hundred and eleven people who are at least 60 years old participated in the project, where 3,514 people completed the baseline survey. The survey collected data including demographic information, daily lifestyle, medical history, and routine physical examination. In particular, we employ ensemble learning and feature selection methods to develop an explainable prediction model for AD and MCI. Five feature selection methods and nine machine learning classifiers are applied for comparison to find the most dominant features on AD/MCI prediction. The resulting model achieves accuracy of 89.2%, sensitivity of 87.7%, and specificity of 90.7% for MCI prediction, and accuracy of 99.2%, sensitivity of 99.7%, and specificity of 98.7% for AD prediction. We further utilize the SHapley Additive exPlanations (SHAP) algorithm to visualize the specific contribution of each feature to AD/MCI prediction at both global and individual levels. Consequently, our model not only provides the prediction outcome, but also helps to understand the relationship between lifestyle/physical disease history and cognitive function, and enables clinicians to make appropriate recommendations for the elderly. Therefore, our approach provides a new perspective for the design of a computer-aided diagnosis system for AD and MCI, and has potential high clinical application value. [ABSTRACT FROM AUTHOR]

Background: With the prolongation of the life expectancy of the Chinese population and the intensification of the aging process of the population, the mental health problems of the elderly have become increasingly prominent. This study aims to explore whether self-employment can promote and how to promote the mental health of the elderly., Method: Based on the 2018 China Longitudinal Aging Social Survey (CLASS) data, this paper uses OLS model and KHB method to verify the impact of self-employment on the mental health of the younger elderly and its mechanism., Results: The results indicate that self-employment can significantly reduce the depression tendency of the younger elderly and promote their mental health. Heterogeneity analysis shows that self-employment has a more significant positive impact on the mental health of the younger elderly who are self-rated healthy, free of chronic diseases and low-level medical service utilization. The mechanism shows that self-employment can indirectly improve the mental health of the younger elderly through income growth effect and self-worth realization effect, in which the self-worth realization effect is greater than the economic effect. It illustrates that with the development of China's economy, the elderly are pursuing more intrinsic values brought by self-employment than economic benefits., Conclusion: In view of the above research results, it is suggested to encourage the elderly to actively participate in social activities, provide policy support for the younger elderly to engage in self-employment, increase government support as well as health guarantee level, and improve the subjective initiative of the elderly to participate in self-employment, so that the society can truly realize the healthy aging of "being useful and productive for the elderly"., (© 2023.

TikTok, as an emerging digital geography, has transformed remote communication to a live, instant, and uncannily realistic interaction. To explore the implications of TikTok on older adults, this paper examines the accounts of older Chinese TikTok celebrities – their participation in TikTok as well as the major discourses of ageing mediated by TikTok. An empirical study was conducted by quantitatively analysing web‐scraped comments on older TikTok celebrities and by interpreting the themes present in these popular TikTok accounts. The empirical results unveil that TikTok facilitates the social interactions of older digital celebrities by creating a caring environment. However, the healthy ageing paradigm promoted by the Chinese government is also promoted by TikTok's recommendation algorithm and platform capitalism. The healthy ageing paradigm prioritises older adults who are healthy and independent, and as a result marginalises those who have a disease or disability or are dependent on others in some way. As a result, the healthy ageing paradigm promoted by TikTok constitutes another form of ageism. Responding to the call to go beyond "the digital", our research contributes to digital geography by examining the geographies of ageing mediated by TikTok. [ABSTRACT FROM AUTHOR]

The Chinese culture of filial piety has historically emphasised children's responsibility for their ageing parents. Little is understood regarding the inverse: parents' responsibility and care for their adult children. This paper uses interviews with 50 families living in rural China's Anhui Province to understand intergenerational support in rural China. Findings indicate that parents in rural China take on large financial burdens in order to sustain patrilineal traditions by providing housing and child care for their adult sons. These expectations lead some rural elders to become migrant workers in order to support their adult sons while others provide live-in grandchild-care, moving into their children's urban homes or bringing grandchildren into their own homes. As the oldest rural generations begin to require ageing care of their own, migrant children are unable to provide the sustained care and support expected within the cultural tradition of xiao. This paper adds to the small body of literature that examines the downward transfer of support from parents to their adult children in rural China. The authors argue that there is an emerging cultural rupture in the practice of filial piety – while the older generation is fulfilling their obligations of upbringing and paying for adult children's housing and child care; these adult children are not necessarily available or committed to the return of care for their ageing parents. The authors reveal cultural and structural lags that leave millions of rural ageing adults vulnerable in the process of urbanisation in rural China. [ABSTRACT FROM AUTHOR]

This paper examines the effect of both cumulative and transitory exposures to air pollution for the same individuals over time on cognitive performance by matching a nationally representative longitudinal survey and air quality data in China according to the exact time and geographic locations of the cognitive tests. We find that long-term exposure to air pollution impedes cognitive performance in verbal and math tests. We provide evidence that the effect of air pollution on verbal tests becomes more pronounced as people age, especially for men and the less educated. The damage on the aging brain by air pollution likely imposes substantial health and economic costs, considering that cognitive functioning is critical for the elderly for both running daily errands and making high-stake decisions.

Scholars who study aging in place generally understand home care and community care as distinct but interrelated concepts. They conceptualise home narrowly as a place with defined boundaries that differentiate 'home' from 'unhome'. In this paper, I propose the term 'institutional home' to describe a space with fluid boundaries between home and unhome that incorporates aspects of both. Here, 'home' is not exclusive to private residential places and homely feelings, but could be constituted outside the private home, with a combination of homely and unhomely feelings. Employing discourse analysis of interviews with older adults and staff, I examine how older adults experience community eldercare centres in China as an institutional home where the practice and meaning of home go beyond one particular space or setting, becoming both home and unhome. This paper contributes to the aging‐in‐place literature by investigating an expanded understanding of home for older adults. [ABSTRACT FROM AUTHOR]

Health risks and hazards caused by the environment have long been one of the most important public issues of concern to the state, society, and the public. At the same time, population aging is becoming a global issue, and residents' health is the most important component of people's livelihood, and residents can only pursue other rights and interests if they can protect their own health. Therefore, based on the micro data from the fifth round of the China Family Panel Studies (CFPS), this paper uses binary logistic regression with propensity score matching (PSM) to analyze the effect of environmental perception on the health status (including mental health and physical health) of middle-aged and older adults. It was found that environmental perceptions significantly affect the depressive state and sickness status of middle-aged and older adults. Among them, middle-aged and older adults who were female, of rural households, with low education and relatively low income were more affected by environmental shocks on their health. Therefore, we should pay attention to the mental and physical health of middle-aged and older adults and change the existing design concept of aging policy: the government should formulate effective policies and increase corresponding social support; and society and families should also give corresponding care and encourage middle-aged and older adults to exercise more and provide reasonable psychological guidance.

Morels are one of the most highly prized edible and medicinal mushrooms worldwide. Therefore, historically, there has been a large international interest in their cultivation. Numerous ecological, physiological, genetic, taxonomic, and mycochemical studies have been previously developed. At the beginning of this century, China finally achieved artificial cultivation and started a high-scale commercial development in 2012. Due to its international interest, its cultivation scale and area expanded rapidly in this country. However, along with the massive industrial scale, a number of challenges, including the maintenance of steady economic profits, arise. In order to contribute to the solution of these challenges, formal research studying selection, species recognition, strain aging, mating type structure, life cycle, nutrient metabolism, growth and development, and multi-omics has recently been boosted. This paper focuses on discussing current morel cultivation technologies, the industrial status of cultivation in China, and the relevance of basic biological research, including, e.g., the study of strain characteristics, species breeding, mating type structure, and microbial interactions. The main challenges related to the morel cultivation industry on a large scale are also analyzed. It is expected that this review will promote a steady global development of the morel industry based on permanent and robust basic scientific knowledge. [ABSTRACT FROM AUTHOR]

Holding large conferences and events usually encourages the corresponding government to upgrade the host city. For this process, incorporating additional costs to increase accessibility for the elderly is a feasible means for a city to develop in an age-friendly manner. Providing evidence-based reports to policy makers is conducive to implementing the policies of age-friendly cities. This study used the scenario method to simulate the effect of promoting the "age-friendly cities" strategy on residents' psychological capital and social engagement (SE). We found that promoting the construction of age-friendly cities can significantly improve residents' psychological capital and SE and that residents from all age groups can benefit. This paper provides an economical means to influence policymakers through evidence-based reports in promoting the development of age-friendly cities. [ABSTRACT FROM AUTHOR]

At present, China's population aging presents the characteristics of large base, fast aging process, and old age, but the research and development of product aging design in China is relatively late, which brings additional pressure to the daily life of the elderly. In such an environment, higher requirements are put forward for product aging design and service provision. Only products or services that timely meet the personalized and diversified needs of different customers can attract customers and improve customer satisfaction. How to design aging products with satisfactory appearance and humanized function is the focus of current research. Based on the product quality division of Kano model, this paper summarizes the domestic mainstream products and their functions. The designed questionnaire data are summarized; reliability and validity analysis, as well as descriptive statistical analysis, is performed on this basis for the constructed product service quality evaluation system. The service quality indicators are divided into three categories according to the Kano model: overall one-dimensional quality, charm quality, and necessary quality. [ABSTRACT FROM AUTHOR]

To verify whether the aging workers' employment conditions become worse in aging society compared to pre-aging society, and, if so, whether discrimination can explain for this kind of phenomenon, using data from the China Health and Nutrition Survey questionnaire (1997, 2000, 2004 and 2006), this paper examines the reemployment of retirees in China's aging society. This paper finds that the aging workers' employment conditions became worse, and discrimination could account for the lower share of elderly rehires in 2004 and 2006, in comparison with 1997 and 2000.

The deepening of aging population inevitably in China will exert a far-reaching influence on national consumption and economic transformation. Based on interprovincial panel data in 2000-2018, this paper measured the ratio of five survival and enjoyment consumptions in disposable incomes, reconstructed the indicators for upgrading the consumption structure, used the bilateral stochastic cutting-edge model, and decomposed the aging population to realize the net effect from the positive and negative effects generated by the consumption structure. The findings indicated that (1) aging population played a positive and negative bilateral effect on upgrading the consumption structure, in which the positive effect upgraded 14.04% of the consumption structure while the negative effect degraded 6.18% of the consumption structure. The comprehensive net effect upgraded 7.86% of the consumption structure. (2) From the perspective of the time effect, under the positive and negative effects of aging population, the consumption structure was upgraded 7.861% on average every year. (3) Regarding the regional effect, the promotion role of aging population was the highest in the eastern region, followed by the west. The middle was the lowest. By combining with estimation results of each province, the promotion role brought by aging population in the northeast and southwest was lower. Based on the above-mentioned research results, this paper proposed some advice for positively developing silver hair economy, promoting the improvement on the consumption structure according to circumstances, developing the perfect aging consumption market, exploring the consumption potential of the elderly, accelerating the urbanization development progress, and stimulating consumption growth relying on the Internet., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Wang, Zhao and Meng.)

Background: China now faces an increasingly aging society which may exert economic pressure in the long run. This study illustrates the spatial pattern and evolution of population aging and economic development in China. The coupling coordination degree of population aging and economic development at the national and provincial levels are calculated and demonstrated, and the spatial patterns and characteristics are investigated., Methods: This paper presents a coupling analysis of the elderly population rate (EPR) and per capita Gross Regional Product (GRP pc ) in China by using the coupling and coordination model. Further, the spatial pattern and evolution of population aging and economic development are investigated based on the standard deviational ellipse. The collected data is at the level of provincial administrative units in mainland China covering the period 2002 to 2020., Results: The results reveal the spatial difference in the coupling and coordination degree between EPR and GRP pc across provinces. The eastern coastal areas are higher than the central and western regions of China. The orientation and directions of EPR are more than GRP pc , indicating that the polarization in population aging is more severe than economic development. Significant positive correlations between coupling coordination degree and sustainable competitiveness are detected., Conclusions: Policymakers should fully consider regional differences and sustainable development in policy formulation of China. The western and northeastern provinces should be given priority in the regional sustainable development plan. At the same time, the coordination between population aging and economic development also requires to be examined especially., (© 2022. The Author(s).)

Age-friendly communities (AFCs) are an important measure for fostering active aging. The key to achieving an age-friendly living environment is to construct or renovate it according to the residents' demands. To date, very few studies have attempted to delve into the AFCs' environmental demand from different groups' perspectives. Based on the theory of place attachment, the aim of this paper is to explore the demand diversity of different groups for the AFC environment. This study employs the nonparametric test and the Ordinal Priority Approach (OPA) to investigate the demands from the residents' perspectives, and is enhanced by incorporating experts' opinions. The empirical analysis shows that residents have a high level of demand for the physical environment (indoor and outdoor) and social environment (community services and social participation). At the same time, experts advocate the importance of using digital technologies to support people aged 45-65 who have higher requirements for a community environment than older adults. The findings also show that other backgrounds, such as gender, living arrangements, and year of the community establishment, lead to different demands. However, the impact of residents' education level, occupation, income, and self-care ability on the environmental demands is low. Based on the research findings, the paper provides some practical suggestions for the future design and development of AFCs.

This paper examines the relationship between community care services and ageing in place in urban China. Using data from the 2010 Sample Survey on Aged Population in Urban/Rural China, and within the framework of a revised version of Andersen's model, the paper applies multilevel models and analyses the effects of community care on the preference between ageing in place and institutional care, and reveals that ageing in place is preferred even in urban China. However, the existence of community care services had no significant effect on the preference for ageing in place. The paper concludes by arguing that China needs to develop its community care services and promote the idea of community care in both culture and policy. Realising ageing in place also requires a multidisciplinary approach. A model of shared care, between family and state, is particularly appropriate for China. [ABSTRACT FROM AUTHOR]

This study examines the effects of the geographical distance between adult offspring and their elderly parents on their support provided to their parents in rural China. Monetary and non-monetary support is closely related to the physical and psychological well-being of the elderly. Three waves of the China Health and Retirement Longitudinal Study (CHARLS) are used to identify a causal effect of the location of the adult offspring on outcomes such as financial transfers to the parents and provision of emotion/physical support. We find that the effects vary with the type of support. The effect of geographical distance on financial support sent by adult children to elderly parents shows a semi-inverted 'U-shaped' trend that first increases and then slowly decreases. The frequency of visit by the adult child to elderly parents decreases significantly as distance increase. Further analysis examines the heterogeneity of these effects. The paper combines theoretical and empirical evidence to illustrate how adult children make use of their limited time and money to provide parental support when they migrate different distances from home.
