Multidimensional Factors Affecting Successful Aging among Empty-Nesters in China Based on Social-Ecological System Theory

Independent and combined associations of handgrip strength and walking speed with cognitive function in older adults: evidence from a national cross-sectional study

OBJECTIVES

Although there have been studies on the association of handgrip strength or walking speed alone with cognitive abilities, few studies have determined the combined associations of handgrip strength and walking speed with cognitive function. Therefore we aimed to explore the independent and combined associations of handgrip strength and walking speed with cognitive function in Chinese older adults using a nationally representative sample.

METHOD

This cross-sectional study included 4,577 adults aged 60 and older. Handgrip strength was measured using a dynamometer and walking speed was assessed using a 2.5-meter walking test. Both handgrip strength and walking speed were organized into low, normal, and high tertiles according to the sample distribution. Cognitive function was measured using the Telephone Interview for Cognitive Status.

RESULTS

Handgrip strength and walking speed were significantly associated with cognitive function. Participants with low handgrip strength or low walking speed separately had a higher rate of lower cognitive function (adjusted odds ratio (OR): 1.22 (95% CI: 1.04 - 1.44) for low handgrip strength; 1.54 (95% CI: 1.31 - 1.81) for low walking speed). Those with both low handgrip strength and low walking speed had an additively higher rate of lower cognitive function (adjusted OR: 1.72 (95% CI: 1.32 - 2.24)).

CONCLUSION

Having low handgrip strength or low walking speed is associated with a greater likelihood of lower cognitive function and vice versa. The concurrence of having low handgrip strength and low walking speed has an additive effect on cognitive function in older adults.

Social Support, Health Behaviors, Self-Esteem, and Successful Aging in a Sub-Saharan African Sample of Older Adults: Test of a Sequential Mediation Model

Background and Objectives

Previous research demonstrates that social support facilitates successful aging across all cultures. However, the factors that potentially mediate the link between social support and successful aging remain unclear. This study examined whether a healthy lifestyle and self-esteem mediate the association between social support and successful aging. It was hypothesized that the relationship between social support (family, friends, and significant other) and successful aging would be serially mediated by both healthy lifestyle and self-esteem.

Research Design and Methods

Participants were 479 Nigerian retirees (53.4% female) aged 60 to 90 years (Mage = 64.81, SD = 6.86). They provided information on relevant demographic variables and completed the following measures: Fantastic Lifestyle Checklist (Fitness Appraisal), Rosenberg Self-esteem Scale, Multidimensional Scale of Perceived Social Support Scale, and Successful Aging Inventory. Three separate regression models (family, friends, and significant other dimensions of social support) were conducted using the Hayes PROCESS macro for SPSS with 5,000 bootstrap estimates.

Results

Controlling for age and sex, family support, significant other support, friends support, healthy lifestyle, and self-esteem were directly associated with successful aging. The association between family support and successful aging was mediated by healthy lifestyle; and this was also seen for friends' support and significant other support. The sequential path from social support to successful aging through healthy lifestyle, and then via improved self-esteem, was significant for family support and significant other support, but not friends support.

Discussion and Implications

Findings suggest that middle-aged to older adults who have strong support from their families and significant others may be more likely to engage in healthy behaviors and, in turn, experience higher levels of self-esteem, thereby aging well.

Significance of an Interprofessional Healthy Aging Program for Community-Dwelling Older Adults: A Narrative Study

Participation is widely recognized as an important health determinant for older adults. Exploring interventions to promote active participation of community-dwelling older adults is an important step in translating current knowledge into practice. Few studies have examined community-level interventions to support older adults' participation. The study purpose was to examine the significance of the lived experiences of community-dwelling older adults who participated in an interprofessional healthy aging promotion program. The specific aims were to uncover the narrative significance of the lived experiences and how they evolved and intertwined with the life histories of the older adults 2 years after the intervention ended. A narrative inquiry design was used. Four key informants participated in two semi-structured interviews and a member-checking process. The data were analyzed from a three-dimensional inquiry space of time and continuity, place and context, and social interactions. The findings affirmed three core threads that wove the participants' lived experiences within the program together with their life histories after the intervention. These were enjoyment, learning, and sharing. Four themes revealed the essential elements of the lived experience, and three others exposed participants' growth and life enrichment, all being fundamental to participation. The 3-year community-level intervention was valued and a novel opportunity for facilitating participation and successful aging. It allowed the participants to acquire an evolved vision of self, have meaningful interactions, develop the means to engage in future community activities, implement new self-care strategies, and establish memories and friendships significant for life participation.

Social-ecological perspective on the suicidal behaviour factors of early adolescents in China: a network analysis

Background

In early adolescence, youth are highly prone to suicidal behaviours. Identifying modifiable risk factors during this critical phase is a priority to inform effective suicide prevention strategies.

Aims

To explore the risk and protective factors of suicidal behaviours (ie, suicidal ideation, plans and attempts) in early adolescence in China using a social-ecological perspective.

Methods

Using data from the cross-sectional project 'Healthy and Risky Behaviours Among Middle School Students in Anhui Province, China', stratified random cluster sampling was used to select 5724 middle school students who had completed self-report questionnaires in November 2020. Network analysis was employed to examine the correlates of suicidal ideation, plans and attempts at four levels, namely individual (sex, academic performance, serious physical illness/disability, history of self-harm, depression, impulsivity, sleep problems, resilience), family (family economic status, relationship with mother, relationship with father, family violence, childhood abuse, parental mental illness), school (relationship with teachers, relationship with classmates, school-bullying victimisation and perpetration) and social (social support, satisfaction with society).

Results

In total, 37.9%, 19.0% and 5.5% of the students reported suicidal ideation, plans and attempts in the past 6 months, respectively. The estimated network revealed that suicidal ideation, plans and attempts were collectively associated with a history of self-harm, sleep problems, childhood abuse, school bullying and victimisation. Centrality analysis indicated that the most influential nodes in the network were history of self-harm and childhood abuse. Notably, the network also showed unique correlates of suicidal ideation (sex, weight=0.60; impulsivity, weight=0.24; family violence, weight=0.17; relationship with teachers, weight=-0.03; school-bullying perpetration, weight=0.22), suicidal plans (social support, weight=-0.15) and suicidal attempts (relationship with mother, weight=-0.10; parental mental illness, weight=0.61).

Conclusions

This study identified the correlates of suicidal ideation, plans and attempts, and provided practical implications for suicide prevention for young adolescents in China. Firstly, this study highlighted the importance of joint interventions across multiple departments. Secondly, the common risk factors of suicidal ideation, plans and attempts were elucidated. Thirdly, this study proposed target interventions to address the unique influencing factors of suicidal ideation, plans and attempts.

Separate and combined associations of obesity and handgrip strength with cognitive function in older adults: A national cross-sectional study in China

This study examined the separate and combined associations of obesity and handgrip strength with cognitive function in older adults. In total 4,839 older adults were included in this cross-sectional study, and their body mass index (BMI) and handgrip strength were measured. Cognitive function was evaluated using the Telephone Interview for Cognitive Status. Three individual categories were created for BMI (normal weight: 18.5≤ BMI < 24.0 kg/m2 overweight: 24.0≤ BMI < 28.0 kg/m2 and obesity: BMI ≥ 28.0 kg/m2 and handgrip strength (low, normal, and high tertiles), and then these categories were pooled together. Logistic regression analyses were used to examine the individual and combined associations of obesity and handgrip strength with cognitive function. Results indicated that overweight adults had a lower rate of lower cognitive function than normal weight adults. There was an inverse association between handgrip strength and cognitive function. Participants with overweight and high handgrip strength had a lower likelihood of lower cognitive function compared to those with normal weight and normal handgrip strength. The findings suggested that overweight or high handgrip strength was associated with lower odds of cognitive decline. Moreover, the concurrence of overweight and high handgrip strength had an additive effect on cognitive function in older adults.

Influencing factors of two-way social support for the old adults in China: A cross-sectional study

This study aims to investigate the status and influencing factors of two-way social support among old adults. A cross-sectional study of 408 convenient samples of old adults was conducted using socio-demographic questionnaire, Brief 2-Way Social Support Scale, Modified Barthel index, General Well-being Schedule, Family APGAR Index, and Lubben Social Network Scale 6. The two-way social support score for old adults in China was (43.74±7.86), with the receiving and giving social support scoring (22.80±4.06) and (20.94±4.52), respectively. The multiple linear regression analysis revealed that family care, residence place, socioeconomic status, and social network were associated with both receiving and giving social support. Chronic diseases and religious beliefs were related to receiving social support, while gender, general well-being, and residence form were related to giving social support. Tailored interventions based on the distinct influencing factors are needed to enhance old adults' social support both as recipients and providers.

Longitudinal correlates of bullying victimization among Chinese early adolescents: A cross-lagged panel network analysis

BACKGROUND

Bullying victimization is a major public health issue often faced by adolescents. This highlights the need to identify the relevant risk factors to inform intervention. Based on the ecological systems theory and applied cross-lagged panel network analysis, this study explored the longitudinal correlates of bullying victimization among Chinese early adolescents.

METHODS

A total of 1686 early adolescents (60.4 % were boys) from the Chinese Early Adolescent Cohort study were included in this study. Bullying victimization and its associated factors were assessed using the self-report questionnaires, which was administered from 2019 (T1), 2021 (T2), and 2022 (T3). The longitudinal relationships between bullying victimization and its correlates were examined using a cross-lagged panel network analysis.

RESULTS

27.0 %, 14.9 %, and 13.2 % of the participants reported being bullied by peers at T1, T2, and T3, respectively. The temporal network suggested that individual-level (sex, depression, and anxiety), family-level (child abuse), school-level (satisfaction with classmates), and social-level (satisfaction with society) factors were associated with bullying victimization. The node with the greatest centrality strength was anxiety. Notably, relationship with teachers and classmates were the unique nodes in the T2 → T3 replication network.

LIMITATIONS

The sample is unrepresentative, as it is from only one middle school.

CONCLUSIONS

The findings provide important insights into bullying victimization prevention and intervention among Chinese early adolescents: 1) highlighting the importance of joint interventions across multiple departments; 2) focusing on the most central factors of bullying victimization; and 3) considering the effect of time when exploring the correlates of bullying victimization.

Associated factors of health-promoting lifestyle of the elderly based on the theory of social ecosystem

OBJECT

To explore the factors related to health-promoting lifestyles of the elderly based on social-ecosystem theory.

DESIGN

A cross-sectional survey study was carried out to include 627 elderly people in communities in three cities of Hebei Province (Shijiazhuang, Tangshan, and Zhangjiakou) from October 2021 to January 2022 for questionnaire survey (601 validly returned cases).

VENUE

Three cities of Hebei Province (Shijiazhuang, Tangshan, and Zhangjiakou).

PARTICIPANTS

627 elderly people.

INTERVENTIONS

A cross-sectional survey study.

MAIN MEASUREMENTS

The questionnaire survey was conducted by using the general demographic data, health promotion life scale, frailty scale, general self-efficacy scale, health engagement scale, General Self-Efficacy Scale, The family Adaptability, Partnership, Growth, Affection, and Resolve scale, and Perceived Social Support Scale.

RESULTS

The total health promotion lifestyle score for the elderly was 100.20±16.21, which was at the lower limit of the good level, with the highest mean score for nutrition (2.71±0.51) and the lowest mean score for physical activity (2.25±0.56). Stepwise linear regression showed that exercise frequency (95% confidence interval (CI) 1.304-3.885), smoking status (95% CI -4.190 to -1.556), self-efficacy (95% CI 0.071-0.185), health management (95% CI 0.306-0.590), frailty (95% CI -3.327 to -1.162) in the microsystem, marital status (95% CI 0.677-3.660), children's attention to the elderly health (95% CI 4.866-11.305), family care in the mesosystem (95% CI 1.365-4.968), and pre-retirement occupation (95% CI 2.065-3.894), living area (95% CI 0.813-3.912), whether receive community-based chronic disease prevention and management services (95% CI 2.035-8.149), social support (95% CI 1.667-6.493) in the macrosystem were the main factors affecting health promotion of life in the elderly (P<0.05). Hierarchical regression analysis showed the microsystem accounted for 17.2%, the mesosystem accounted for 7.1%, and the macrosystem accounted for 11.4%.

CONCLUSION

The health promotion lifestyle of the elderly in Hebei Province was at the lower limit of good level. Among them, exercise frequency, children's attention to the elderly health, and pre-retirement occupation played a major role in relation to the health-promoting lifestyle of the elderly. Hence, it needs the joint action of individuals, families, and society to promote the elderly to adopt the health promotion lifestyle and realize healthy aging.

Handgrip strength is positively associated with successful aging in older adults: A national cross-sectional study in China

OBJECTIVES

Muscle strength gradually decreases with advancing age. This study aimed to explore the relationship between handgrip strength and successful aging and its specific dimensions in older adults using a nationally representative sample.

METHODS

A total of 5269 adults aged 60 and older were included in this study. Handgrip strength was measured using a dynamometer and was organized into quartiles by sex. Successful aging was defined by Rowe and Kahn's conceptual model including the following five dimensions: (a) no major diseases; (b) freedom from disability; (c) high cognitive function; (d) good psychological status; and (e) active social engagement in life. Logistic regression models were used to examine the association between handgrip strength and successful aging and its specific dimensions.

RESULTS

The prevalence of successful aging was found to be 35.1 % in Chinese older adults. Compared to older adults with handgrip strength in the first quartile, those with handgrip strength in the second quartile, third quartile, and fourth quartile had a higher probability of successful aging (adjusted odds ratio (OR): 1.40 (95 % CI: 1.16, 1.69) to 2.06 (95 % CI: 1.70, 2.50)). We further found that the association between handgrip strength and successful aging was related to different ages.

CONCLUSION

This study suggested that there is a close association between handgrip strength and successful aging. Older adults who have greater handgrip strength can successfully deal with the challenges of aging. For older people, keeping a high level of muscle strength in late life may be helpful to the constant successful aging.

β-Hydroxybutyrate Regulates Activated Microglia to Alleviate Neurodegenerative Processes in Neurological Diseases: A Scoping Review

This scoping review aimed to summarise the effects of the ketone body β-hydroxybutyrate. The review details the revealed pathways and functional properties following its intervention in the context of neurodegenerative diseases. In this study, 5 research publications that met the inclusion and exclusion criteria were shortlisted. Following the intervention, we discovered a tendency of reduced inflammatory status in microglia, as evidenced by lower levels of pro-inflammatory mediators produced, reduced microgliosis in afflicted tissues, and enhanced cognitive functions in neurodegenerative models. We found that there is a significant overlap in the mechanism of action of β-hydroxybutyrate (BHB) via activation of the G-protein-Coupled Receptor 109A (GPR109a) receptor and deactivation of the inflammasome complex. Furthermore, although comparing outcomes can be challenging due to the heterogeneity in the study model, the results we have assembled here were consistent, giving us confidence in the intervention's efficacy. We also discussed new studies where BHB is involved in various roles in regulating inflammation in microglia, allowing for fresh therapeutic targets against neurodegeneration. This brief review provides evidence to support the huge potential of BHB in the treatment of neurodegenerative illnesses.

Promoting the Integration of Elderly Healthcare and Elderly Nursing: Evidence from the Chinese Government

The increase of the aging population in China and the rise of the concept of healthy aging have accelerated the transformation and upgrading of the traditional elderly nursing pattern. Nevertheless, there is a critical limitation existing in the current situation of China's elderly care, i.e., the medical institutions do not support elderly nursing and the elderly nursing institutions do not facilitate access to medical care. To eliminate the adverse impact of this issue, twelve ministries and commissions of the Chinese government have jointly issued a document, i.e., the Several Opinions on Further Promoting the Development of Combining the Healthcare with the Elderly care (SOFPDCHE), to provide guidance from the government level for further promoting the integration of elderly healthcare and elderly nursing. Under this background, this paper constructs a healthcare-nursing information collaboration network (HnICN) based on the SOFPDCHE, proposing three novel strategies to explore the different roles and collaboration relationships of relevant government departments and public organizations in this integration process, i.e., the node identification strategy (NIS), the local adjacency subgroup strategy (LASS), and the information collaboration effect measurement strategy (ICEMS). Furthermore, this paper retrieves 484 valid policy documents related to "the integration of elderly healthcare and elderly nursing" as data samples on the official websites of 12 sponsored ministries and commissions, and finally confirms 22 government departments and public organizations as the network nodes based on these obtained documents, such as the National Health Commission of the People's Republic of China (NHC), the Ministry of Industry and Information Technology of the People's Republic of China (MIIT), and the National Working Commission on Aging (NWCA). In terms of the collaboration effect, the results of all node-pairs in the HnICN are significantly different, where the collaboration effect between the NHC and MIIT is best and that between the NATCM and MIIT is second best, which are 84.572% and 20.275%, respectively. This study provides the quantifiable results of the information collaboration degree between different government agencies and forms the optimization scheme for the current collaboration status based on these results, which play a positive role in integrating elderly healthcare and elderly nursing and eventually achieving healthy aging.
