Longitudinal analysis of the mediating role of self-perception of aging in the relationship between frailty and intrinsic capacity: A cross-lagged mediation model. Arch Gerontol Geriatr 2024; 120:105336. [PMID: 38301318 DOI: 10.1016/j.archger.2024.105336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/06/2024] [Accepted: 01/18/2024] [Indexed: 02/03/2024]
Abstract
OBJECTIVES The causal relationship between intrinsic capacity and frailty in older adults, as well as the underlying temporal mechanisms, remained poorly understood. The study aimed to investigate the causal association between intrinsic capacity and frailty while exploring the potential mediating role of self-perception of aging. MEASUREMENTS A survey was conducted with a sample of 429 participants who completed measures of intrinsic capacity, self-perception of aging, and frailty at baseline and were followed for one year. The relationships between these variables were assessed using an autoregressive cross-lagged model. RESULTS The study found reciprocal associations between intrinsic capacity and frailty (p < 0.01). Furthermore, the results indicated that self-perception of aging partially mediated the effect of frailty at baseline (T1) on intrinsic capacity at one-year follow-up (T2) (β = -0.02, confidence interval: [-0.055, -0.004]). However, the reverse causation was not observed. CONCLUSIONS AND IMPLICATIONS This study demonstrates a bidirectional causal relationship between intrinsic capacity and frailty in older adults. Self-perception of aging plays a significant mediating role in this relationship. Older adults with a worse level of frailty should be made aware of the potentially vicious cycle related to self-perception of aging, which can negatively affect their intrinsic capacity. Maintaining a positive self-perception of aging may help preserve physical and psychological reserves, maintain intrinsic capacity, and slow the decline of frailty.

Abstract
WHO defines ageism as stereotypes, prejudice, and discrimination based on age. Ageism is a multidimensional concept that encompasses multiple components related to the individual, the social group, and the institution in different cultural and environmental settings. In people ageing with HIV these elements include self-stigma, discrimination in society, and experiences in care, many of which are unique to older people. In this Position Paper, we use experience of people with HIV and clinicians taking care of them to explore these issues in high-income countries. The intersectionality of multiple -isms, which affect the lives of older people living with HIV, and ageism enhance several HIV-related issues, including self-inflicted stigma, and loneliness. Research is needed to explore how ageism contributes to worse physical, mental, and social wellbeing outcomes for people with HIV. The model of care for older people living with HIV needs to go beyond virological success by adopting a geriatric mindset, which is attentive to the challenge of ageism and is proactive in promoting a comprehensive approach for the ageing population. All stakeholders and the community should work together to co-create institutional strategies and educational programmes and enable respectful intergenerational dialogue to foster a stigma-free future for older people living with HIV.

Abstract
This article updates and extends an earlier meta-analysis (Westerhof et al., 2014) on the longitudinal effects of subjective aging (SA) on health outcomes. A systematic search in different databases (APA PsycInfo, PubMed, Web of Science, and Scopus) resulted in 99 articles, reporting on 107 studies. Participants: Studies had a median sample size of 1,863 adults with a median age of 66 years. A randomized effect meta-analysis showed a significant, small effect (likelihood ratio = 1.347; 95% confidence interval [1.300, 1.396]; p < .001), similar in magnitude to the previous meta-analysis of 19 studies. Although the results showed high heterogeneity in the longitudinal link between SA and health outcomes, there were no differences in effects according to chronological age of participants, welfare state status (more or less developed social security system), length of follow-up, type of health-related outcome, or quality of the study. Effects were stronger for multiitem measures of self-perceptions of aging than for the frequently used single-item measures assessing subjective age, especially for indicators of physical health. Based on this meta-analysis, building on five times more studies than the 2014 review, we consider the associations of measures of SA with health and longevity across time as robust, albeit small in size. Future research should concentrate on the clarification of pathways mediating the relation between SA and health outcomes, as well as potential bidirectional effects.

[PMID: 36936666 PMCID: PMC10023232 DOI: 10.1155/2023/5212712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 07/11/2022] [Accepted: 07/21/2022] [Indexed: 03/12/2023]
Abstract
Network public opinion represents public social opinion to a certain extent and has an important impact on formulating national policies and judgment. Therefore, China and other countries attach great importance to the study of online public opinion. However, the current researches lack the combination of theory and practical cases and lack the intersection of social and natural sciences. This work aims to overcome the technical defects of traditional management systems, break through the difficulties and pain points of existing network public opinion risk management, and improve the efficiency of network public opinion risk management. Firstly, a network public opinion isolation strategy based on the infectious disease propagation model is proposed, and the optimal control theory is used to realize a functional control model to maximize social utility. Secondly, blockchain technology is used to build a network public opinion risk management system. The system is used to conduct a detailed study on identifying and perceiving online public opinion risk. Finally, a Chinese word segmentation scheme based on Long Short-Term Memory (LSTM) network model and a text emotion recognition scheme based on a convolutional neural network are proposed. Both schemes are validated on a typical corpus. The results show that when the system has a control strategy, the number of susceptible drops significantly. Two days after the public opinion is generated, the number of susceptible people decreased from 1,000 to 250; 3 days after the public opinion is generated, the number of susceptible people stabilized. 2 days after the public opinion is generated, the number of lurkers increased from 100 to 620; 3 days after the public opinion is generated, the number of lurkers stabilized. The data demonstrate that the designed isolation control strategy is effective. Changes in public opinion among infected people show that quarantine control strategies played a significant role in the early days of Corona Virus Disease 2019. The rate of change in the number of infections is more affected when quarantine controls are increased, especially in the days leading up to the outbreak. When the system adopts the optimal control strategy, the influence scope of public opinion becomes smaller, and the control becomes easier. When the dimension of the word vector of emergent events is 200, its accuracy may be higher. This method provides certain ideas for blockchain and deep learning technology in network public opinion control.
