Project description:ObjectivesThis report aims to examine income-related inequalities in informal care among older people with functional limitations in China.MethodsData are drawn from the 2005, 2008, 2011, and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey. Erreygers concentration index, concentration index, and horizontal inequity index are used to examine inequalities in informal care. A random effects model is then used to investigate the relationship between household income and informal care.ResultsThere is no significant association between household income and the probability of receiving informal care. However, we observed a significant positive association between household income and hours of informal care received, indicating that those with higher household income receive more hours of informal care compared to those with lower household income. The degree of this inequality increases as the number of functional limitations increases.DiscussionLower household income is associated with lower intensity of informal care received, particularly for older people with more functional limitations. Policies are required to support low-income older people with more functional limitations.

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

Project description:The objectives of this review article are to facilitate deeper research and better policy analysis for healthy aging, which not only means surviving to old ages in good health, but also mean the economics and society of our country would be aging healthily, with sound policy and intervention programs. Toward these objectives, we introduce the Chinese Longitudinal Healthy Longevity Survey (CLHLS), which has been conducted by Center for Healthy Aging and Development Studies, National School of Development of Peking University since 1998. We present a comprehensive and summarized introduction of the CLHLS study design, sample distributions, contents, general quality assessment and availability of the CLHLS data collected. Such an introduction would be helpful for our colleagues who may be interested in using this unique and more-than-fourteen-year longitudinal survey data resource for deeper interdisciplinary research and better policy analysis on healthy aging. To illustrate how the unique data resources of CLHLS may be useful, we also summarize and discuss ten selected healthy aging policy related research based on data from the CLHLS. Finally, we discussed the future perspectives using the unique and rich CLHLS datasets.

Project description:As health challenging rural elderly in an aging population, more attention is being paid on impact of family intergenerational support on the health of the elderly. This paper investigates the effects of children's intergenerational economic support and non-economic support on physical, mental, and functional health of rural elderly in China in the mean while. This paper applies the 2014 Chinese Longitudinal Healthy Longevity Survey (CLHLS), in particular, applying exploratory factor analysis to ascertain latent variables and Structural Equation Model (SEM), and analyzes the impacts of "Upward" intergenerational support on health of rural elderly. As resulted, after controlling the socioeconomic status of the rural elderly, the family "upward" intergenerational support influences the elderly's physical health at a percentage of 11.7%, mental health 29.8%, and physiological function 12.6%. Moreover, "Upward" economic support has a positive effect on physiological function (P<0.05). "Upward" non-economic support has negative effects on physiological function and mental health (P<0.05), while it has a positive effect on physical health. In addition, economically independent rural elderly are more likely to benefit from the health of "upward" intergenerational support, especially mental health. In particular, those results are robust. "Upward" intergenerational support plays an important role for the health of rural elderly. For the rural elderly of economic independence, to improve the quality of care and spiritual support, it is important to solve the health problems. In addition, it is necessary to build a comprehensive old-age security and support system for family, community, and society jointly to improve the health of the rural elderly.

Project description:BackgroundThe mental health and living arrangements of older adults are worthy of attention. Previous studies have pointed out that the living arrangements may be related to older adults' depression. However, it has not been found that studies concern the relationship between actual living arrangements, living arrangement preferences, and the fit between living arrangement preferences and reality and depression in older adults, so we carried out this study.MethodsThe data from the Chinese longitudinal healthy longevity survey were used in this study. With the older adults' depression as the dependent variable and the living arrangement related variables as the independent variable, we constructed three binary-logistic regression analysis models to explore the potential relationship between living arrangement related variables and depression in older adults.ResultsWe found that the actual living arrangements, living arrangement preferences, and the fit between living arrangement preferences and reality are significantly correlated with depression in older adults. Specifically, older adults living alone or only with the spouse are at greater risk of depression. Older adults who prefer living alone or only with the spouse are at relatively low risk of depression. Older adults whose living arrangement preferences do not match reality have a higher risk of depression.ConclusionThe living arrangement related variables are significantly correlated with depression in older adults. In addition to the actual living arrangements, living arrangement preferences and whether the living arrangement preferences fit with reality are also related to the depression of older adults.

Project description:PurposeTo investigate the association between polypharmacy, anxiety, and depression among Chinese older adults.Patients and methodsThe data used in this study were from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), the 2018 wave. Polypharmacy status was measured by the accumulation of self-reported medications. Anxiety and depression were assessed by the Generalized Anxiety Disorder (GAD-7) scale and the Center for Epidemiologic Studies Depression Scale (CES-D-10), respectively. Logistic regression models were performed.ResultsA total of 2484 Chinese older adults (female: 1321, 53.2%) aged from 60 to 117 years old were included in the analysis. Regression analysis showed that polypharmacy was associated with depression after controlling for the covariates. No association was observed between polypharmacy and anxiety.ConclusionThere was a suggestive link between polypharmacy and depression among Chinese older adults. Having polypharmacy might be an indicator for the possible depression among this population, but a comprehensive assessment of polypharmacy is necessary.

Project description:BackgroundThe combined effect of cognitive impairment (CoI) and frailty on falls is controversial. This study aimed to explore whether older adults with cognitive frailty (CF) were at a higher risk of falls than those with only CoI or frailty and to present a fall prediction model based on CF.MethodsA total of 4,067 adults aged ≥ 60 years were included from the Chinese Longitudinal Healthy Longevity Survey through face-to-face interviews. Cognitive function and frailty were assessed using the mini-mental state examination scale and frailty index, respectively. Logistic regression was used to determine fall-associated risk factors and develop a fall prediction model. A nomogram was then plotted. The model performance was evaluated using the area under the curve (AUC), concordance index (C-index), and calibration curve. All analyses were performed using SPSS and R statistical packages.ResultsThe prevalence of CF and falls were 1.4 and 19.4%, respectively. After adjusting for covariates, the odds ratio of CF, frailty only, and CoI only for falls were 2.27 (95% CI: 1.29-3.97), 1.41 (95% CI: 1.16-1.73), and 0.99 (95% CI: 0.43-2.29), respectively. CF, sex, age, hearing difficulty, depression, anxiety, disability in instrumental activities of daily living, and serious illness in the past 2 years were independently associated with falls. A prediction model based on these factors yielded an AUC of 0.646 and a C-index of 0.641.ConclusionCognitive frailty (CF) exerted a cumulative effect on falls than did CoI or frailty alone. Joint assessments of cognitive function and frailty status may be beneficial for fall risk screening in community. A prediction model using CF as a factor could be helpful for this process.

Project description:Background: Inflammation has been reported to play an important role in frailty syndrome. The neutrophil-lymphocyte ratio (NLR) has recently emerged as an informative marker for systematic inflammation. However, few studies have examined the association between NLR and frailty. This study aims to examine the association between NLR and frailty in community-dwelling older adults. Methods: Community-dwelling older adults aged ≥ 65 years in the 2011 (n = 2,354) and 2014 (n = 2,458) waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were included. Frailty status was determined using the 38-item frailty index (FI) and categorized into "robust" (FI ≤ 0.1), "pre-frail" (0.1 < FI ≤ 0.21), or "frail" (FI > 0.21). NLR was calculated using a derived formula: NLR = (white blood cell-lymphocyte)/lymphocyte. Results: A total of 3,267 participants were finally included. In cross-sectional analyses, participants with higher NLR levels had increased likelihood of frailty [the 3rd quartile: adjusted odds ratio (OR) = 1.29; 95% confidence interval (CI): 1.02-1.63; the 4th quartile: OR = 1.59; 95% CI: 1.23-2.02) compared with those in the 1st quartile group. During the 3-year follow-up, 164 of the 1,206 participants, robust or pre-frail at baseline, developed frailty, and 197 of the 562 participants, robust at baseline, developed pre-frailty or frailty. Among the robust and pre-frail participants in 2011, after multivariate adjustment, those in the 4th quartile group had a higher frailty incidence than those in the 1st quartile group (OR = 2.06; 95% CI: 1.18-3.59). Among the robust participants in 2011, those in the 4th quartile group also had a higher pre-frailty or frailty incidence than those in the 1st quartile group (OR = 1.95; 95% CI: 1.07-3.55). Conclusion: Among community-dwelling older adults, higher NLR levels were found to be associated with increased odds of prevalent and incident frailty.

Project description:BackgroundAlthough frailty is a common geriatric syndrome in old adults, a simple method to assess the degree of frailty in a person has not yet been established. In this study we have tried to establish the association between calf circumference (CC) and frailty among older Chinese people.MethodsWe used the data obtained from the 2014 edition of the Chinese Longitudinal Healthy Longevity Survey; 1216 participants aged ≥60 years were included for the study. Body mass index, CC and waist circumference measurement data, and laboratory test results were collected. Frailty status was measured using the frailty index (FI). Participants were then classified into non-frail (FI < 0.25) and frail (FI ≥ 0.25) groups.ResultsThere were 874 participants (71.9%) in the non-frail group and 342 (28.1%) in the frail group. The CC was significantly different between the two groups (31.54 ± 4.16 versus 28.04 ± 4.53, P < 0.001). Logistic regression analysis revealed that CC (odds ratio = 0.947, 95% confidence interval: 0.904-0.993, P = 0.023) was an independent impact factor associated with frailty. The CC value of 28.5 cm was considered the best cut-off value in women with area under the curve (AUC) was 0.732 (P < 0.001) and 29.5 cm in men with AUC was 0.592 (P = 0.004);We created a simple prediction model for frailty that included age,sex and CC:[Formula: see text]P = elogit(P) /1 + elogit(P), and AUC is 0.849 (P < 0.001).ConclusionsCC is a convenient and predictable marker of frailty in older adults.

Project description:Background and Objective: Few studies have explored the relationship between malnutrition measured by the Geriatric Nutritional Risk Index (GNRI) and cognitive performance. This study aimed to investigate the association of malnutrition with cognitive function in the Chinese population. Methods: It was a prospective longitudinal study and used three waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) data in 2011-2012, 2014, and 2017-2018. Participants aged 60 years or older without mental illness and cerebrovascular diseases were eligible. The GNRI was used to assess nutritional status as follows: normal nutrition (a GNRI > 98), mild malnutrition (92 ≤ a GNRI ≤ 98), and moderate-to-severe malnutrition (a GNRI < 92). Cognitive performance was evaluated by the Mini-Mental State Examination (MMSE) scores. The relationship between the GNRI and cognitive function was analyzed using a linear mixed-effects model. Results: A total of 1,632 subjects were analyzed, including 741 males and 891 females. Of these, 65.0, 19.4, and 15.6% of subjects were at normal nutritional status, mild, and moderate-to-severe malnutrition, respectively. After adjusting for potential confounders, participants under mild and moderate-to-severe malnutrition status have a lower MMSE score [β (95% CI): -0.95 (-1.60, -0.25) and -1.39 (-2.21, -0.57), respectively], compared with those having normal nutrition. Also, there was a linear trend in the association of malnutrition risk with cognitive function in the total population [β (95% CI): -0.74 (-1.13, -0.35)]. However, a significant association of malnutrition with cognitive function was observed only among illiterate females aged above 90 years. Conclusion: This study suggested that there was a significant relationship between the GNRI and cognitive function in the Chinese elderly. Furthermore, subjects with more serious malnutrition have a worse cognitive function, especially in the oldest illiterate females. Clinicians should put more emphasis on assessing the nutritional and cognitive status of the elderly to timely intervene and prevent cognitive impairment.
