Relationship between hukou conversion and psychological integration of rural older migrants: the mediating effect of accessibility to health resources.

OBJECTIVE: This study investigates the relationship between hukou conversion and the psychological integration of rural older migrants, exploring the mediating role of accessibility to health resources. METHODS: The 3,963 valid samples of rural older migrants included in the study were sourced from the 2017 China Migrants Dynamic Survey (CMDS). The study established a multiple linear regression model for estimation and utilized inverse probability-weighted regression adjustment (IPWRA) method to correct for the selection bias of hukou conversion. RESULTS: Compared to older migrants with rural hukou, merit-based (ß = 0.384, 95% CI: 0.265 to 0.504), family-based (ß = 0.371, 95% CI: 0.178 to 0.565) and policy-based (ß = 0.306, 95% CI: 0.124 to 0.487) converters have significantly higher psychological integration. These findings remain robust even after addressing the potential issue of endogenous selection bias using the IPWRA method. Bootstrap mediating effect tests indicate that hukou conversion can indirectly affect psychological integration through the mediator role of health resources accessibility. CONCLUSION: Accessibility of health resources mediates the association between hukou conversion and psychological integration. Policymakers should enhance the implementation of hukou conversion, strengthen the health resource guarantee system, and achieve a deeper psychological integration among rural older migrants.

Social participation, subjective well-being, and cognitive function as serial mediators between tooth loss and functional limitations in older Chinese adults.

BACKGROUND: Although tooth loss appears to be related to functional limitations, the mechanisms that underpin this relationship are unknown. We sought to address this knowledge gap by examining a multiple mediation hypothesis whereby tooth loss is predicted to indirectly affect functional limitations through social participation, subjective well-being, and cognitive function. METHODS: This study included 7,629 Chinese adults from the 2017/2018 Chinese Longitudinal Healthy Longevity Survey wave. The serial mediation effects were examined using Model 6 in the Hayes' PROCESS macro for SPSS. RESULTS: Tooth loss was significantly related to functional limitations. There was a direct (ß = - 0.0308; 95% CI, - 0.0131 to - 0.0036) and indirect (ß = - 0.0068; 95% CI, - 0.0096 to - 0.0041) association between tooth loss and instrumental activities of daily living (IADL) limitations, but only an indirect correlation with activities of daily living (ADL) limitations (ß = - 0.0188; 95% CI, - 0.0259 to - 0.0121). Social participation, subjective well-being, and cognitive function serially mediated the relationship between tooth loss and ADL/IADL limitations. CONCLUSION: The association between tooth loss and functional limitations is serially mediated by social participation, subjective well-being, and cognitive function. Our findings underscore the necessity of considering psychological and social factors as integrated healthcare approaches for the functional health of older adults.

Longitudinal associations between social relationships and cognitive function among Chinese older adults: The mediating role of healthy lifestyles.

BACKGROUND: We aimed to explore whether social relationships and cognitive function were reciprocally related and whether healthy lifestyles mediate their association. METHODS: This study included 3372 Chinese adults from the years 2014-2018 wave of the Chinese Longitudinal Healthy Longevity Survey. RESULTS: Baseline social relationships were negatively associated with a change in cognitive function (ß = -0.030, p = 0.043). Participants with a 1 standard deviation (SD) increase in social relationships had an approximately 6% reduced risk of developing cognitive impairment. However, baseline cognitive function did not independently predict social relationships. The association between △social relationships and △cognitive function was partially mediated by △a healthy lifestyle (B = 0.025, 95% CI = 0.013-0.041). CONCLUSIONS: The association between social relationships and cognitive function may be unidirectional. Policies that promote cognitive function based on social relationships would benefit by taking into account lifestyle factors.

Instrumental support primarily provided by adult children and trajectories of depressive symptoms among older adults with disabilities in rural China.

OBJECTIVES: This study aimed to examine the trajectories of depressive symptoms over a 5-year period in a sample of community-dwelling older adults with disabilities in rural China, and the association between duration of instrumental support primarily provided by adult children and the trajectories of depressive symptoms. METHODS: Data were drawn from three waves of the China Health and Retirement Longitudinal Study (2011-2015). The sample included 1,466 older adults living in rural areas aged 60 and over who had at least one child in all three waves. Duration of instrumental support provided by adult children was measured by the number of waves that older adults received instrumental support primarily from any adult children in the data collection. Growth mixture modelling was used to identify the trajectory classes of depressive symptoms among these older adults, and logistic regression was used to examine the association between duration of instrumental support primarily provided by adult children and the trajectory classes of depressive symptoms. RESULTS: This study identified two distinct trajectories of depressive symptoms among the respondents: high but decreasing levels of symptoms and persistently low levels of symptoms. Respondents who received a longer duration of instrumental support primarily from adult children were more likely to have high but decreasing symptoms after controlling for other covariates. CONCLUSION: The findings have important implications for promoting the mental health of older adults with disabilities in rural China. There are still very limited long-term care services and programs are available for older adults, particularly in rural China. It is critical to develop these services at both community and institutional levels to meet the care needs of older adults and their families.

Association between frailty and cognitive function in older Chinese people: A moderated mediation of social relationships and depressive symptoms.

BACKGROUND: To date, few studies have focused on examining either the direct or indirect effect of physical frailty on cognitive impairment. This study aimed to investigate the moderating effects of social relationships, including their individual components in the role of depressive symptoms as a mediator between frailty and cognitive impairment. METHODS: This study included a total of 7525 Chinese older adults from the 2017-2018 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Mediation analyses and moderated mediation effect analysis fully adjusted for all potential confounding factors were conducted. RESULTS: Significant correlations were found between frailty, depression, social relationships, and cognitive function. Depression partially mediated the association of frailty with cognitive function [B = -0.198; 95 % confidence interval (CI): (-0.258, -0.143)]. Social relationships moderated the effect of frailty on cognitive function through both path b (depression-cognitive function) [B = 0.137; 95 % CI: (0.045, 0.230)], and path c' (frailty-cognitive function) [B = 0.870; 95 % CI: (0.562, 1.178)]. In addition, social activities and social networks moderated both the direct and indirect effect of the moderated mediation model. Social support only moderated the direct effect. LIMITATIONS: The cross-sectional design of this study precludes any conclusion from the results as to the causality of cognitive impairment. CONCLUSIONS: Social relationships moderated both the direct and indirect effects of depressive symptoms on the association between frailty and cognitive impairment. The findings suggest that interventions, such as paying attention to the mental health of old people and improving the quality of social relationships, may help break the link between frailty and cognitive impairment.

Outpatient Visits among Older Adults Living Alone in China: Does Health Insurance and City of Residence Matter?

This study aimed to examine the association between health insurance, city of residence, and outpatient visits among older adults living alone in China. A sample of 3173 individuals was derived from "Survey on Older Adults Aged 70 and Above Living Alone in Urban China" in five different cities. Logistic regression models indicated that older adults living alone who had urban employee basic medical insurance, urban resident basic medical insurance, and public medical insurance were more likely to have outpatient visits than those without any health insurance. After controlling the number of chronic diseases, only those with public medical insurance were more likely to have outpatient visits than uninsured older adults. Additionally, older adults who resided in Shanghai and Guangzhou were more likely to have outpatient visits than those in Chengdu, whereas older adults who were in Dalian and Hohhot were less likely to have outpatient visits. To improve the equity of outpatient visits among older adults living alone in China, policy efforts should be made to reduce fragmentation of different health insurance plans, expand the health insurance coverage for older adults, provide programs that consider the needs of this special group of older adults, and reduce the inequality in health resources and health insurance policies across cities.

Access to Community Living Infrastructure and Its Impact on the Establishment of Community-Based Day Care Centres for Seniors in Rural China.

Community-based day care centres play an important role in service delivery for Chinese seniors. Little research has examined how community living infrastructure has influenced the establishment of these day care centres in rural communities. The purposes of this study were: (1) explore regional differences in community living infrastructure; and (2) to examine the impact of such infrastructure on the establishment of day care centres for Chinese seniors in rural communities. The data were derived from “The Fourth Sample Survey on the Living Conditions of Elderly People in Urban and Rural China (2015)”. The establishment of at least one day care centre was the outcome of interest, which was dichotomized at the community level into the establishment of at least one day care centre or the absence of any day care centres. Logistic regression analysis was employed to examine the impact of various community living infrastructural characteristics on the establishment of day care centres. The results showed that of the 4522 rural communities surveyed in 2015, only 10.1% had established at least one day care centre. Community living infrastructural characteristics that were significantly associated with the establishment of day care centres were the availability of cement/asphalt roads, natural gas, tap drinking water, sewage systems, and centralized garbage disposal. Our findings suggest that the significant association between community-level characteristics, especially community living infrastructure, and the establishment of rural day care centre for seniors may inform policy decision making.

Long-term care arrangements in rural China: review of recent developments.

Developing long-term care systems for the elderly has become an increasingly urgent policy issue in China, especially in rural areas. This article provides an overview of the current status of long-term care development in rural China and discussion on the future development of institutional care and its policy implications. Formal long-term care systems are emerging but remain in the preliminary stages of development. Several policy considerations and practical implications deserve further attention: increases in regional and national government funding, integration of long-term care with the acute health care system, and creating more multilevel and multifunctional LTC facilities with a well-trained and skilled workforce.
