Understanding the Wellbeing of the Oldest-Old in China: A Study of Socio-Economic and Geographical Variations Based on CLHLS Data

Socioeconomic support, quality of life, and prognosis of frailty among the older adults

Background

Although socioeconomic support is recommended for frailty management, its association with the prognosis of frailty is unclear.

Methods

Using data from participants aged ≥65 years in the Chinese Longitudinal Healthy Longevity Survey (2008-2018), the associations between socioeconomic support (source of income, medical insurance, community support, living status), onset of prefrailty/frailty, and worsening of prefrailty, were analyzed using multinominal logistic regression models. The associations between self-reported low quality of life (QoL) and reversion of prefrailty/frailty were analyzed using multivariate logistic regression models. Associations with mortality risk were analyzed using Cox proportional hazard regression models.

Results

A total of 13,859 participants (mean age: 85.8 ± 11.1 years) containing 2056 centenarians were included. Financial dependence was a risk factor for low QoL among prefrail/frail individuals, but not among robust individuals. Having commercial or other insurance, and receiving social support from the community were protective factors for low QoL among prefrail/frail individuals and for the worsening of prefrailty. Continuing to work was a risk factor for low QoL, but a protective factor for worsening of prefrailty. A negative association between continuing to work and mortality existed in prefrail individuals aged <85 years and ≥85 years. Living alone was a risk factor for low QoL, but was not significantly associated with frailty prognosis.

Conclusions

Prefrail and frail individuals were vulnerable to changes in socioeconomic support and more sensitive to it compared with robust individuals. Preferential policies regarding financial support, social support, and medical insurance should be developed for individuals with frailty.

Geographic differences in psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease: A multicenter study in China

OBJECTIVE

We aimed to explore the geographic differences in psychological symptoms, sleep quality, and quality of life (QoL) among adult patients with inflammatory bowel disease (IBD).

METHODS

A unified questionnaire was developed to collect data on psychological status and QoL of IBD patients from 42 hospitals across 22 provinces, municipalities, and autonomous regions in China's mainland from September 2021 to May 2022.

RESULTS

A total of 2478 patients with IBD were surveyed. The proportions of patients with anxiety (28.5% vs 23.1%), depression (32.3% vs 27.8%), and poor QoL (44.8% vs 32.2%) were significantly higher in patients from the northern region compared to the southern region (all P < 0.05). In the western region, the proportions of patients with anxiety (31.9% vs 23.0%), depression (37.7% vs 26.7%), sleep disturbances (64.5% vs 58.5%), and poor QoL (44.9% vs 34.8%) were significantly higher than in the eastern and central regions (all P < 0.01). Patients from inland regions had significantly higher rates of anxiety (27.1% vs 23.3%), depression (32.5% vs 26.0%), sleep disturbance (62.0% vs 57.7%), and poor QoL (43.5% vs 29.9%) compared to those from coastal regions (all P < 0.05). In economically underdeveloped areas, the proportions of patients with depression (33.1% vs 28.5%) and poor QoL (52.0% vs 32.4%) were significantly higher than in economically (relatively) developed areas (both P < 0.05).

CONCLUSION

There are significant geographic differences in psychological symptoms, sleep quality, and QoL among Chinese patients with IBD, which might provide valuable insights for global IBD research and clinical practice.

Enhancing understanding of healthy aging based on time-varying dependencies among multidimensional health, life satisfaction, and health behaviors of older adults aged 60 years and over

BACKGROUND

Healthy aging is a process of not only achieving good health but also increasing the life satisfaction of older adults aged 60 years and over, in which health behaviors play an important role. There is a lack of research on the time-varying dependencies between health, life satisfaction, and health behaviors, impeding a deeper understanding of healthy aging.

PURPOSE

To develop an integrated framework for modeling the interrelationships among the components of healthy aging between multiple time slices.

METHODS

Based on the Chinese Longitudinal Healthy Living Survey (CLHLS) data in the three waves of 2011/2012, 2014, and 2017/2018, Bayesian network and dynamic Bayesian network are jointly employed to study the relationships among the components of healthy aging within one time slice, as well as to explore the time-varying dependencies among the components between time slices.

RESULTS

The results of structure learning reveal the direction of effects between different dimensions of health, with mental health and social health affecting physical health and self-rated health affecting both physical and mental health. In addition, health behaviors are found to affect mental health and social health, while self-rated health can influence life satisfaction. The parameters learned from the data show the magnitude and direction of concurrent effects, one-period lagged effects and two-period lagged effects between the factors, which find that the time-varying dependencies vary but are generally positive, long-term, and accumulative over time. In addition, the results of autoregressive effects show the positive predictive effects of health and life satisfaction.

CONCLUSIONS

It confirms the influence pathway from health behaviors to multidimensional health to life satisfaction, and the time-varying dependencies among the components of healthy aging, which facilitates a deeper understanding of healthy aging. Combining the results of autoregressive effects and descriptive statistics, it further indicates that healthy aging is a comprehensive result arising from interactions of multiple factors. Policymakers should guide older adults aged 60 years and over to adopt healthier behaviors and ensure the long-term sustainability and continuity of policies.

Everyday life experiences of Chinese community-dwelling oldest old who live alone at home

PURPOSE

Older adults aged ≥ 80 years living alone at home are more likely to experience challenges. Daily life experiences regarding living alone are still limited in the Asian context. This study explored the everyday life experiences of older Chinese residents living alone at home. Research questions included: (1) How do Chinese community-dwelling old people describe everyday life experiences related to living alone? (2) What kind of difficulties and needs do Chinese community-dwelling older people living alone face in everyday lives? (3) How do Chinese community-dwelling older people cope with challenges faced in their everyday lives related to living alone?

METHODS

This was qualitative descriptive research. Purposive sampling was adopted to recruit 13 participants aged 80-92 years of age from communities and one hospital. Semi-structured interviews were conducted to collect data which was analysed by conventional content analysis.

RESULTS

Three themes were identified: theme 1-difficulty in finding a sense of belonging, theme 2-striving to maintain independence, theme 3-hard to gain a sense of control.

CONCLUSIONS

This study provided novel insights into understanding the difficulties and needs of Chinese older people living alone at home. Three key challenges and associated strategies they used to cope with in daily lives were presented.

Dietary patterns from mid-through later-life in relation to sarcopenia risk over 20 years among Chinese community-dwelling oldest old individuals

BACKGROUND

Evidence regarding how dietary patterns (DPs) from mid- (60 years old) to later-life (over 80 years old) affect sarcopenia risk in old age is scarce.

METHODS

We included 7267 participants aged ≥80 years from the Chinese Longitudinal Healthy Longevity Survey in 2018. The Simplified Healthy Eating Index (SHE index) based on nine dietary variables was used to measured DPs and changes in DPs, with a higher score indicating better diet quality. The term "Mid-life" DPs denoted dietary habits at the age of 60 whereas "Later-life" DPs referred to dietary habits acquired over 80 years old. Sarcopenia risk was evaluated using the SARC-CalF questionnaire. We applied multivariable adjusted logistic regression models to investigate the cross-sectional association between DPs in a life course and sarcopenia risk in 2018 after adjusting for potential confounders including sociodemographic characteristics, lifestyle risk factors, and unfavorable health conditions. Several sensitivity analyses were conducted to verify the robustness of the results.

RESULTS

We found that healthier DPs during both mid- and later-life were associated with a decreased odds of sarcopenia risk, with adjusted odds ratios (ORs) of 0.69 (95 % confidence interval [CI]: 0.54-0.88) and 0.84 (95 % CI: 0.71-0.99), respectively. The odds of sarcopenia risk were also decreased among those with healthier DPs over a period of 20 years (OR = 0.80, 95 % CI: 0.69-0.93). For each nutrient consumption, participants who had high-quality fish consumption both in mid- and later-life had a 23 % decreased odds of sarcopenia risk (OR = 0.77, 95 % CI: 0.67-0.88) compared with those who had low-quality fish consumption all the time. The results were largely unchanged in sensitivity analyses.

CONCLUSIONS

Our findings highlight the importance of maintaining healthy dietary habits throughout life to reduce the risk of sarcopenia in old age.

Self-rated physical and mental health among older adults 80 years and older: cross-sectional results from a National community sample in Thailand

BACKGROUND

The aim of this study was to assess the self-reported physical health (SRPH) and self-reported mental health (SRMH) of older adults 80 years and older in Thailand.

METHODS

We analyze national cross-sectional data from the Health, Aging and Retirement in Thailand (HART) in 2015. Physical and mental health status was assessed by self-report.

RESULTS

The sample included 927 participants (excluding 101 proxy interviews), 80-117 years, median age 84 years [interquartile range (IQR) 81-86 years]. The median SRPH was 70.0 (IQR = 50.0-80.0), and median SRMH was 80.0 (IQR = 70.0 to 90.0). The prevalence of (good) SRPH was 53.3%, and the prevalence of (good) SRMH was 59.9%. In the final adjusted model, low or no income, living in the Northeastern, Northern and Southern region, daily activity limitations, moderate/severe pain, having one or two or more physical conditions, and low cognitive functioning were negatively associated, and higher physical activity was positively associated with good SRPH. No or low income, residing in the northern region of the country, daily activity limitations, low cognitive functioning, and probable depression were negatively associated with good SRMH, and physical activity was positively associated with good SRMH.

CONCLUSION

SRPH and SRMH was relatively high rated among the oldest old in Thailand, and influenced by various social, economic, and health-related factors. Special attention should be given to those with no or low income, those living in the non-central regions and those having no or low formal social engagement. Health care and other services should improve physical activity, financial support, and physical and mental care management to promote physical and mental well-being of older adults 80 years and older in Thailand.

Age-varying relationships between family support and depressive symptoms in Chinese community-dwelling older adults

BACKGROUND

Adequate family support is an important factor in reducing the risk of depressive symptoms in older adults. We aimed to explore the age-varying relationships of family support and depressive symptoms in community-dwelling older adults.

METHODS

A total of 22,163 person-waves of older adults aged 60 to 85 years from the China Health and Retirement Longitudinal Survey were included. Depressive symptoms were assessed by the Center for Epidemiological Studies Depression Scale. Family support was divided into instrumental family support and emotional family support. A Time-Varying Effects Model was utilized to analyze the age-varying relationships.

RESULTS

There were age-varying relationships between family support and depressive symptoms in community-dwelling older adults. Around age 70 was an important turning point of age. In instrumental family support, access to living care can reduce the risk of depressive symptoms in almost all age groups. At least medium-level financial support was required to be protective against depressive symptoms, and high-level financial support was necessary after age 70. In emotional family support, meeting children with high frequency was significantly associated with a lower risk of depressive symptoms before age 70. Contacting children with low or medium frequency added the risk of depressive symptoms before age 70.

LIMITATIONS

Limited sample size of participants aged 80 years and above, lack of assessment for expectations of family support.

CONCLUSIONS

Providing the appropriate type and intensity of family support for older adults at a suitable age was encouraged. Future research should further verify and explicate the age-varying relationships longitudinally.

From Agricultural Green Production to Farmers' Happiness: A Case Study of Kiwi Growers in China

Happiness is the ultimate goal of everyone working and earning wealth. At present, in the vast rural areas of China, the excessive and unscientific application of chemical fertilizers and pesticides is raising serious concerns for environmental protection. The Chinese government has strongly promoted agricultural green production as an alternative to the previous agricultural paradigm that sacrificed the environment. A shift towards agricultural green production has become imperative. However, will it bring "happiness" to farmers who partake in this shift? Using data from 1138 farmers in Shanxi, Northwest China, throughout 2022, this article examines the relationship between the adoption of agricultural green production and farmers' happiness. The empirical findings indicate that the adoption of agricultural green production can considerably increase farmers' happiness and that the more types of agricultural green technologies that are implemented, the greater the happiness of farmers. Further mediating effect analysis suggests that this mechanism occurs through raising the absolute and relative income, mitigating agricultural pollution, and elevating the social status. The findings shed new light on the effect of farmers' economic behavior on their happiness and underline the necessity of implementing relevant policies.

Do Community Home-Based Elderly Care Services Improve Life Satisfaction of Chinese Older Adults? An Empirical Analysis Based on the 2018 CLHLS Dataset

Population aging has become a major challenge for the Chinese government. Based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2018, this study adopts the propensity score matching (PSM) method to assess the effect of community home-based elderly care services (CHECS) on the life satisfaction of the elderly in China. The results demonstrate that CHECS can improve their life satisfaction. Compared with life care services (LCS) and medical care services (MCS), the positive effect of spiritual and cultural services (SCS) and reconciliation and legal services (RLS) is more obvious. Moreover, the heterogeneity test demonstrates that the effect is more significant for the elderly who live with their families, whose activities of daily living are unrestricted, and whose depression levels are lower. The results obtained indicate that CHECS need precise policies for different elderly groups, attention to the positive impact of SCS and RLS on the life satisfaction of the elderly, and the substantive effectiveness of LCS and MCS.

Effect of the Use of Home and Community Care Services on the Multidimensional Health of Older Adults

Home and community care is an important way to actively respond to population aging and to promote healthy aging. This study aims to estimate the effect of using home and community care services on the multidimensional health of older adults. We used data from the China Health and Retirement Longitudinal Study conducted in 2018 and relied mainly on the propensity score matching method for data analysis. The results showed that using home and community care increased the probability of maintaining and improving physical health by 2.9%, decreased the score of depression by 0.471, and improved the score of cognitive function by 0.704. Using home and community care also increased the probability of actively participating in life by 4.1% and elevated the score of life satisfaction by 0.088. The heterogeneity analysis showed that the use of home and community care had a significant effect on promoting all health indicators in rural older adults and a more obvious promoting effect on the social adaptation of urban older adults. Using home and community care significantly promoted the multidimensional health of people aged 60 to 79 years but had no impact among people aged ≥ 80 years. The use of home and community care significantly improved all health indicators in non-disabled older adults. Whereas, it only improved the levels of cognitive function and life satisfaction in disabled older people. Using this form of care significantly improved all health indicators in those with low socio-economic status, but it only had a partial positive effect on the multidimensional health of those with high socio-economic status. Our results are of importance to the government as they may be used to further improve the quality of home and community care services for the targeted older population.

The Impact of Family Socioeconomic Status on Elderly Health in China: Based on the Frailty Index

China is about to enter a moderate aging society. In the process of social and economic development, the family socioeconomic status and health status of the elderly have also changed significantly. Learning the impact of family socioeconomic status on elderly health can help them improve family socioeconomic status and better achieve healthy and active aging. Using the data of the Chinese Longitudinal Healthy Longevity Survey in 2018, this study firstly analyzed the impact of family socioeconomic status on elderly health using the multivariate linear regression model and quantile regression model, the heterogeneity of different elderly groups using subsample regression, and the mediation effects of three conditions associated with the family socioeconomic status of the elderly. The results show that family socioeconomic status has a negative effect on the frailty index, that is, it has a positive impact on elderly health. Family socioeconomic status has a higher positive impact on the health status of the middle and lower age elderly and rural elderly. Overall living status and leisure and recreation status both have mediation effects, while health-care status has no mediation effect.

Are there gender differences in the trajectories of self-rated health among chinese older adults? an analysis of the Chinese Longitudinal Healthy Longevity Survey (CLHLS)

BACKGROUND

Self-rated health (SRH) is a good predictor of morbidity and mortality. Extensive research has shown that females generally report poorer SRH than males but still tend to live longer. Previous studies used cross-sectional or pooled data for their analyses while ignoring the dynamic changes in males' and females' SRH statuses over time. Furthermore, longitudinal studies, especially those that focus on older adults, typically suffer from the incompleteness of data. As such, the effect of dropout data on the trajectories of SRH is still unknown. Our objective is to examine whether there are any gender differences in the trajectories of SRH statuses in Chinese older adults.

METHODS

The trajectories of SRH were estimated using the pattern-mixture model (PMM), a special latent growth model, under non-ignorable dropout data assumption. We analyzed the Chinese Longitudinal Healthy Longevity Survey (CLHLS) data of 15,613 older adults aged 65 years and above, collected from 2005 to 2014.

RESULTS

The results demonstrated the effect of non-ignorable dropout data assumptions in this study. The previous SRH score was negatively associated with the likelihood of dropping out of the study at the next follow-up survey. Our results showed that both males and females in China perceive their SRH as decreasing over time. A significant gender difference was found in the average SRH score (female SRH was lower than male SRH) in this study. Nonetheless, based on the results obtained using the PMM, there are no gender differences in the trajectories of SRH at baseline as well as in the rate of decline among the total sample. The results also show that males and females respond to SRH predictors similarly, except that current drinking has a more pronounced positive effect on males and healthcare accessibility has a more pronounced positive effect on females.

CONCLUSIONS

Our results suggest that missing data have an impact on the trajectory of SRH among Chinese older adults. Under the non-ignorable dropout data assumptions, no gender differences were found in trajectories of SRH among Chinese older adults. Males and females respond to SRH predictors similarly, except for current drinking habit and healthcare accessibility.

The effect of social participation on income-related inequality in health outcome among Chinese older adults

Background

This study aimed to investigate the effect of social participation on income-related inequality in health outcome among older adults in China.

Methods

The panel data used in this study were sourced from the 2011 and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Furthermore, this study employed a concentration index to assess the income-related inequality in health outcome. Moreover, this study used the decomposition method of concentration index to analyse the effect of social participation on income-related inequality in health outcome.

Results

The total concentration index of Instrumental Activity of Daily Living (IADL) status decreased from 0.0257 in 2011 to 0.0172 in 2014. Furthermore, the total concentration index of psychological health decreased from 0.0309 in 2011 to 0.0269 in 2014. The decomposition analysis indicates that social participation made a major contribution to the pro-rich inequality in IADL status. Moreover, the results also indicate that social participation made a minor contribution to the pro-rich inequality in psychological health.

Conclusions

This study demonstrated that overall there were pro-rich inequalities in IADL status and psychological health among older adults in China. Moreover, social participation made a major contribution to the pro-rich inequality in IADL status, while it made a minor contribution to the pro-rich inequality in psychological health.

A Comparative Psycholinguistic Study on the Subjective Feelings of Well-Being Outcomes of Foreign Language Learning in Older Adults From the Czech Republic and Poland

Positive psychology has recently seen unprecedented rise and has reached vast achievements in the area of quality of life (QoL) improvement. The purpose of this study is to show that there are different aspects of well-being that make healthy older people motivated to learn a foreign language at a later age. The research was conducted in the Czech Republic and Poland in two groups of learners aged 55 years and more. The experimental group consisted of 105 Czech respondents who were targeted with an online questionnaire with the aim to determine the level of FLL outcomes connected to QoL in healthy older adults in their L2 acquisition. The second experimental group (n = 100) was established of Polish seniors who attended similar language courses. The findings of the research clearly show that FLL has an irreplaceable role as one of several non-pharmacological strategies utilized to improve the aging process and reduce drawbacks of aging. The results indicate that seniors' overall satisfaction and subjective feelings of well-being are enormously high when attending foreign language classes at older age. FLL, therefore, creates an environment that can enhance QoL of older adults that can be supplemented by other means such as well-balanced diet, other social activities, sport and physical activity, music, or computer games. All these intervention methods can significantly improve QoL of older adults and the parties engaged and/or responsible for taking care of older generation should take it into serious consideration.

All-cause mortality rate in China: do residents in economically developed regions have better health?

Background

Urban-rural disparities have been extensively investigated, while most investigators overlooked urban-suburban-rural variations in population health. Although regional disparities in East-West China have been largely discussed, limited attention has been directed to the interaction between regional differences and urban-suburban-rural disparities. This study aims to analyze urban-suburban-rural variations in all-cause mortality rates across four geographic regions in China.

Methods

Data came from China’s National Census Survey and public statistical yearbooks in 2000 and 2010. Urban districts, county-level cities, and counties were respectively defined as urban, suburban, and rural areas. We obtained 2322 areas, including 2148 areas with two observations and 174 areas with only one observation. Data visualization was performed to depict geographic variations and changes in all-cause mortality rates. Five hierarchical linear regression analyses with generalized estimating equations (GEE) were employed to analyze variations in all-cause mortality rates over time. Demographic and socioeconomic attributes were introduced as covariates.

Results

Despite an overall decline in all-cause mortality rate, rural residents generally achieved worse health than urban and suburban counterparts. In contrast, urban-suburban disparities could be fully explained by demographic and socioeconomic differences. In addition, Northeastern and Central residents achieved better health than Eastern and Western residents. Last, there existed urban/suburban-rural disparities in all regions, except Northeastern, where urban/suburban-rural disparities were eliminated after controlling for socioeconomic and demographic attributes.

Conclusion

Even though suburban and rural areas were often merged, there exist urban/suburban-rural disparities in population health. Furthermore, urban/suburban-rural disparities vary across regions.

Factors associated with health-related quality of life (HRQoL): differential patterns depending on age

PURPOSE

The aims of this study were: (1) to analyze age differences in health-related quality of life (HRQoL) between the young old (aged 65-84) and the oldest old (aged 85 and over), and (2) to investigate three types of predictors: (a) physical health [Basic Activities of Daily Living (BADL), Instrumental Activities of Daily Living, comorbidity, use of medication], (b) global cognitive ability and (c) psychosocial factors, specifically personality traits, social support and emotional functioning (positive and negative affect and life satisfaction), which may influence the HRQoL of both the young old and the oldest old.

METHOD

A cross-sectional study was conducted with 257 healthy community-dwelling elderly people. HRQoL was assessed using the SF-36 Health Survey. Functional and health status, global cognitive ability and psychosocial variables were also assessed.

RESULTS

Age differences were found in HRQoL, with the oldest old scoring lower for this variable. Multiple stepwise hierarchical linear regression analyses revealed that, in relation to the physical health component, use of medication, BADL and positive affect had the greatest influence among the young old (65-84), whereas among the oldest old, neuroticism and the BADL were the most influential factors. As regards the mental health component, neuroticism, use of medication and positive affect were the main predictor variables among the young old, while neuroticism and negative affect had the greatest influence among the oldest old group.

CONCLUSION

The oldest old had a poorer HRQoL in both dimensions measured (physical and mental). There appear to be differences between the determinants of HRQoL for young old and oldest old adults, suggesting that these associations change with age.
