Contributions of Psychosocial Factors and Physical Activity to Successful Aging

Weight loss rather than weight gain has a detrimental effect on successful aging in older adults: A 4-year longitudinal study in China

This study explored the effect of weight change on successful aging in older adults. A total of 1865 adults (≥65 years) were divided into the weight gain group (weight gain ≥5 %), the weight loss group (weight loss ≥5 %), and the weight stable group (weight change <5 %) according to weight changes over 4 years. Results showed that compared to the stable weight, the weight loss is associated with a lower rate of successful aging (OR=0.64, 95 % CI: 0.49-0.83), and the association was found greater in women (OR=0.61, 95 % CI: 0.43-0.86) and young-old adults (OR=0.66, 95 % CI: 0.41-0.88) than their counterparts. However, no significant association was found between weight gain and successful aging. The findings suggest that weight loss rather than weight gain in older adults has a detrimental impact on successful aging, and this detrimental impact is greater in women and young-old adults.

Satisfaction with the Exercise Program and Successful Aging Among Older Adults Who Exercise Regularly: The Multiple Mediation of Physical Self-Efficacy and Exercise Adherence

OBJECTIVES

As the Republic of Korea transitions towards a super-aged society, the health and mental well-being of older adults are emerging as critical issues. While many researchers are focusing on successful aging among older adults who participate in exercise, there is a research gap in the Korean literature regarding the preconditions that foster this outcome. Therefore, this study analyzed the relationship between satisfaction and exercise, physical self-efficacy (PSE), exercise adherence, and successful aging among Korean older adults who exercise regularly.

METHODS

The participants were 369 (234 male and 135 female) older adults aged 65 or older living in the Republic of Korea, with an average age of 69.91 years. Data were collected from March 2024 to June 2024 and analyzed using descriptive statistics, correlation analysis, and structural equation modeling.

RESULTS

There was no problem with the model fit. Satisfaction with exercise positively affected PSE (β = 0.317, p < 0.001), exercise adherence (β = 0.487, p < 0.001), and successful aging (β = 0.669, p < 0.001). PSE positively affected exercise adherence (β = 0.356, p < 0.001), and exercise adherence positively affected successful aging (β = 0.190, p < 0.05). Furthermore, PSE (β = 0.019, p < 0.01) and exercise adherence (β = 0.081, p < 0.05) mediated the relationship between satisfaction with exercise and successful aging.

CONCLUSIONS

Satisfaction with exercise is important for promoting successful aging among Korean older adults who exercise. Satisfaction with exercise can increase their efficacy for performing physical activities and encourage them to continue exercising. This can ultimately lead to a happy life in old age.

Relationship Between Life Satisfaction and Psychological Characteristics Among Community-Dwelling Oldest-old: Focusing on Erikson's Developmental Stages and the Big Five Personality Traits

OBJECTIVE

To clarify the relationship between life satisfaction and the psychological characteristics of the oldest-old, and explore the factors for achieving mental health and longevity.

DESIGN

This cross-sectional study conducted questionnaire surveys and face-to-face interviews as part of a larger prospective cohort study.

SETTING

Arakawa Ward, a district in Tokyo, Japan.

PARTICIPANTS

A total of 247 oldest-old individuals from two age groups, 85+ (aged 85-87 years) and 95+ (aged 95 years or older).

MEASUREMENTS

Life satisfaction was assessed using the Satisfaction with Life Scale (SWLS), developmental stages of the elderly (Erikson's 8th and 9th stages, i.e., ego integrity, and gerotranscendence), and the Big Five personality traits (extraversion, agreeableness, openness, conscientiousness, and neuroticism) using the NEO-Five Factor Inventory. Multiple regression analyses were performed to examine the relationship between the SWLS scores and each assessment, controlling for age, sex, education, activities of daily living, depressive symptoms, and cognitive function.

RESULTS

The SWLS scores of 85+ were positively correlated with scores of ego integrity, extraversion, and conscientiousness. Contrastingly, the SWLS scores of 95+ were positively correlated with gerotranscendence scores.

CONCLUSIONS

Psychological characteristics associated with the level of life satisfaction among community-dwelling oldest-old individuals were identified, but a causal relationship between these factors and life satisfaction was not established. Ego integrity, extraversion, conscientiousness, and gerotranscendence may be associated with enhanced life satisfaction and mental health in the oldest-old. Further, the factors associated with life satisfaction in the 85+ and 95+ age groups varied, suggesting that life satisfaction among the oldest-old has different foundations in different age groups.

Effects of tai chi, ba duan jin, and walking on the mental health status of urban older people living alone: the mediating role of social participation and the moderating role of the exercise environment

With the global trend of aging, lacking of interpersonal communication and spiritual support and companionship have had a great impact on the mental health of older people living alone. This study examines the multifaceted impacts of engaging in tai chi, ba duan jin, and walking on the mental wellbeing of older people residing alone in urban areas. Additionally, this research aims to explore the association between tai chi, ba duan jin, and walking, and the mental health status of urban older people living alone, by considering the mediating influence of social participation and the moderating influence of the exercise environment. To do so, 1,027 older people living alone in six Chinese cities were investigated using the Physical Activity Rating Scale (PARS-3), the Geriatric Health Questionnaire (GHQ-12), the Social Participation Indicator System Scale, and the Exercise Environment Scale. SPSS 25.0 was utilized for conducting mathematical statistical analysis, specifically for doing linear regression analysis. Additionally, AMOS was employed to develop the study model. We found that a significant negative correlation between tai chi, ba duan jin, and walking and mental health status; among these, tai chi had the greatest impact on the mental health status of urban older people living alone. Social participation mediated the relationship between tai chi, ba duan jin, walking, and mental health status, and the exercise environment had a moderating effect on this relationship. The findings of this study indicate that tai chi, ba duan jin, and walking have a positive impact on the mental health of urban older people living alone, which can be influenced by the mediating efficacy of social participation and the moderating effect of the exercise environment.

Early aging and premature vascular aging in chronic kidney disease

Aging is the progressive decline of body functions and a number of chronic conditions can lead to premature aging characterized by frailty, a diseased vasculature, osteoporosis, and muscle wasting. One of the major conditions associated with premature and accelerated aging is chronic kidney disease (CKD), which can also result in early vascular aging and the stiffening of the arteries. Premature vascular aging in CKD patients has been considered as a marker of prognosis of mortality and cardiovascular morbidity and therefore requires further attention. Oxidative stress, inflammation, advanced glycation end products, fructose, and an aberrant gut microbiota can contribute to the development of early aging in CKD patients. There are several key molecular pathways and molecules which play a role in aging and vascular aging including nuclear factor erythroid 2-related factor 2 (Nrf-2), AMP-activated protein kinase (AMPK), sirtuin 1 (SIRT1), and klotho. Potential therapeutic strategies can target these pathways. Future studies are needed to better understand the importance of premature aging and early vascular aging and to develop therapeutic alternatives for these conditions.

How to Promote Gerotranscendence in Older Adults? A Scoping Review of Interventions

Gerotranscendence is a psychosocial theory that proposes older adults experience a mindset shift in multiple dimensions (cosmic, coherence, solitude), associated with different constructs, such as life satisfaction and well-being. Increasing studies are employing gerotranscendence, but the practical aspects of how gerotranscendence can be developed are still underexplored. This review involved an assessment of the size and scope of the existing literature on interventions related to gerotranscendence and their effect on participants' well-being. Six databases were searched, and eight studies were selected: five were observational, while three were randomized control trials. Findings showed that gerotranscendence can be developed through weekly thematic encounters. Moreover, the interventions examined in the selected studies were described as having positively impacted participants' mental health and life satisfaction. Future studies should explore gerotranscendence interventions using a rigorous methodology and long-term follow-up data to add consistency to these findings.

Effectiveness of Otago Exercise Program on Successful Aging within Older Women with Migrant Children Referring to Public Health Centers in Shiraz City, Iran

Background: Successful aging (SA) is considered an indicator of satisfaction of older people. This study aimed to evaluate the effectiveness of the Otago Exercise Program (OEP) on SA among older women. Materials and Methods: quasi-experimental research with a control group was conducted in 2021 on 120 older women in Shiraz city, south Iran. Eligible samples were selected by a three-stage cluster sampling method and were classified into two equal intervention and control groups. Eight training sessions (exercises) were conducted for the intervention group using the OEP. SA questionnaire was completed at the beginning and 2 months after the intervention. The data were analyzed using the IBM-SPSS version 26, and the effect sizes were extracted. Results: The mean age of samples in the intervention and control groups was 69.71 + 59.59 and 68.83 + 5.08 years, respectively. Although there was no significant difference in the mean scores of SA between the two groups at the beginning of the study, 2 months after the intervention implementation, the mean scores of SA increased significantly in the intervention group (t = 8.57, p ≤ .001). Conclusion: It seems that OEP is an effective strategy for supporting SA in older people.

Analyzing Successful Aging and Longevity: Risk Factors and Health Promoters in 2020 Older Adults

Geriatric syndromes (GSs) and aging-associated diseases (AADs) are common side effects of aging. They are affecting the lives of millions of older adults and placing immense pressure on healthcare systems and economies worldwide. It is imperative to study the factors causing these conditions and develop a holistic framework for their management. The so-called long-lived individuals-people over the age of 90 who managed to retain much of their health and functionality-could be holding the key to understanding these factors and their health implications. We analyzed the health status and lifestyle of the long-lived individuals and identified risk factors for GSs. Family history greatly contributes to the health and prevention of cognitive decline in older adults. Lifestyle and certain socioeconomic factors such as education, the age of starting to work and retiring, job type and income level, physical activity, and hobby were also associated with certain GSs. Moreover, the levels of total protein, albumin, alpha-1 globulins, high-density lipoprotein, free triiodothyronine, and 25-hydroxyvitamin D were direct indicators of the current health status. The proposed mathematical model allows the prediction of successful aging based on family history, social and economic factors, and life-long physical activity (f1 score = 0.72, AUC = 0.68, precision = 0.83 and recall = 0.64).

Psychosocial Mediation of Light-Moderate Physical Activity and Cognitive Performance among Adults Aged 60+ in China

Physical activity is a key determinant of healthy ageing; yet, little is known about the varying degrees of benefits by intensity nor the mediating mechanisms that operate through psychosocial health. Leveraging structural mediation analysis using the 2018 China Health and Retirement Longitudinal Study (CHARLS) national survey data, we screened 4371 community-dwelling older adults, and investigated the mediation mechanism of psychosocial health on the link between light-moderate physical activity and cognitive performance. Physical activity intensity, psychosocial health, and cognitive performance were measured by the international physical activity questionnaire (IPAQ), the Center for Epidemiological Studies Depression Scale (CESD), and the mini-mental state examination (MMSE) instruments, respectively. Results show that, while light physical activity (LPA) and moderate physical activity (MPA) both significantly contribute to better cognitive performance, psychosocial health is a significant mediator only for LPA but not for MPA. For direct pathways, both LPA (std. β = 0.062, p < 0.001, 95% confidence interval = 0.032−0.091) and MPA (std. β = 0.049, p = 0.001, 95% CI = 0.019−0.078) have significant influence on cognitive performance. For mediation pathways, results show that there exists only one indirect channel through which psychosocial health mediates the influence of LPA (std. β = 0.024, p < 0.001, 95% CI = 0.016−0.033), which accounts for 27.9% of the total effect linking LPA and cognitive performance. Findings uncover an important indirect psychosocial mediation channel through which LPA affects cognitive performance among older adults.

Utilization of Host and Microbiome Features in Determination of Biological Aging

The term 'old age' generally refers to a period characterized by profound changes in human physiological functions and susceptibility to disease that accompanies the final years of a person's life. Despite the conventional definition of old age as exceeding the age of 65 years old, quantifying aging as a function of life years does not necessarily reflect how the human body ages. In contrast, characterizing biological (or physiological) aging based on functional parameters may better reflect a person's temporal physiological status and associated disease susceptibility state. As such, differentiating 'chronological aging' from 'biological aging' holds the key to identifying individuals featuring accelerated aging processes despite having a young chronological age and stratifying them to tailored surveillance, diagnosis, prevention, and treatment. Emerging evidence suggests that the gut microbiome changes along with physiological aging and may play a pivotal role in a variety of age-related diseases, in a manner that does not necessarily correlate with chronological age. Harnessing of individualized gut microbiome data and integration of host and microbiome parameters using artificial intelligence and machine learning pipelines may enable us to more accurately define aging clocks. Such holobiont-based estimates of a person's physiological age may facilitate prediction of age-related physiological status and risk of development of age-associated diseases.

Ageing rate of older adults affects the factors associated with, and the determinants of malnutrition in the community: a systematic review and narrative synthesis

BACKGROUND

Malnutrition negatively impacts on health, quality of life and disease outcomes in older adults. The reported factors associated with, and determinants of malnutrition, are inconsistent between studies. These factors may vary according to differences in rate of ageing. This review critically examines the evidence for the most frequently reported sociodemographic factors and determinants of malnutrition and identifies differences according to rates of ageing.

METHODS

A systematic search of the PubMed Central and Embase databases was conducted in April 2019 to identify papers on ageing and poor nutritional status. Numerous factors were identified, including factors from demographic, food intake, lifestyle, social, physical functioning, psychological and disease-related domains. Where possible, community-dwelling populations assessed within the included studies (N = 68) were categorised according to their ageing rate: 'successful', 'usual' or 'accelerated'.

RESULTS

Low education level and unmarried status appear to be more frequently associated with malnutrition within the successful ageing category. Indicators of declining mobility and function are associated with malnutrition and increase in severity across the ageing categories. Falls and hospitalisation are associated with malnutrition irrespective of rate of ageing. Factors associated with malnutrition from the food intake, social and disease-related domains increase in severity in the accelerated ageing category. Having a cognitive impairment appears to be a determinant of malnutrition in successfully ageing populations whilst dementia is reported to be associated with malnutrition within usual and accelerated ageing populations.

CONCLUSIONS

This review summarises the factors associated with malnutrition and malnutrition risk reported in community-dwelling older adults focusing on differences identified according to rate of ageing. As the rate of ageing speeds up, an increasing number of factors are reported within the food intake, social and disease-related domains; these factors increase in severity in the accelerated ageing category. Knowledge of the specific factors and determinants associated with malnutrition according to older adults' ageing rate could contribute to the identification and prevention of malnutrition. As most studies included in this review were cross-sectional, longitudinal studies and meta-analyses comprehensively assessing potential contributory factors are required to establish the true determinants of malnutrition.

The Association of Dietary Habits and Lifestyle Characteristics with Successful Aging among Older Greek Origin Individuals Living in France, Canada, and Greece: The Epidemiological Mediterranean Islands Study (MEDIS)

The aim of the present work was to investigate the association of dietary habits and lifestyle characteristics with successful aging among native Greeks and Greeks of Diaspora (Canada and France). During 2005-2019, 2,434 Greek men and women, living in Greece, in France, and in Canada, over 65 years of age were enrolled voluntarily in the study. Anthropometric, clinical and socio-demographic characteristics, dietary habits, and lifestyle parameters were derived through standard procedures, while successful aging was evaluated using the validated Successful Aging Index (SAI, range 0-10). The SAI of the overall sample was 2.8 ± 1.4. Greeks of Diaspora had higher SAI levels compared to their counterparts in Greece (p's < .001). However, there was no difference between Greeks of Canada and these of France (p > .05). Actually, Greeks of Diaspora had almost 1.9 units higher SAI compared to native Greeks (p < .001). Work and financial status, dietary and lifestyle behaviors (i.e., physical activity, smoking habits), and several clinical characteristics (i.e., history of hypertension and hypercholesterolemia) were statistically different between the three groups (all p's < .05). Greeks of Diaspora had higher SAI levels, probably because of their healthier lifestyle practices, which mainly depend on their traditions and cultural background of their homelands and living conditions in the host countries.

Premature Aging in Chronic Kidney Disease: The Outcome of Persistent Inflammation beyond the Bounds

Over the last hundred years, life expectancy in developed countries has increased because of healthier living habits and the treatment of chronic pathologies causing premature aging. Aging is an inexorable, time-dependent, multifactorial process characterized by a series of progressive and irreversible physiological changes associated with loss of functional, psychological, and social capabilities. Numerous factors, such as oxidative stress, inflammation, and cellular senescence, and an irreversible geriatric syndrome known as frailty, contribute to human body deterioration in aging. The speed of aging may differ between individuals depending on the presence or absence of multiple factors (genetic and/or environment) and the subsequent misbalance of homeostasis, together with the increase of frailty, which also plays a key role in developing chronic diseases. In addition, pathological circumstances have been reported to precipitate or accelerate the aging process. This review investigated the mechanisms involved in the developing pathologies, particularly chronic kidney disease, associated with aging.

What intensity of exercise is most suitable for the elderly in China? A propensity score matching analysis

BACKGROUND

The strategy of successful ageing is an important means to deal with the challenges of the current ageing society. This paper aims to explore the effects of different intensities of physical activity on the successful ageing of the elderly.

METHODS

Our data were from wave 4 of the China Health and Retirement Longitudinal Survey (CHARLS), involving 9026 residents aged 60 years and older. The intensity of physical activity was divided into three levels: vigorous, moderate and mild. The concept of successful ageing adopted a four-dimensional model of life satisfaction added to the theoretical model of Rowe and Kahn's. Propensity score matching (PSM) with controlling nine confounding factors were used to analyse the effects of different intensities of physical activity.

RESULTS

The percentage of successful ageing was 1.88% among all subjects. Among them, 30.26, 29.57 and 29.40% of the elderly often participated in vigorous, moderate and mild physical activity, respectively. The results of PSM showed that participation in moderate activity increased the probability of successful ageing of the elderly by 0.76-0.78% (P < 0.001), while participation in vigorous and mild physical activity had no significant effect on successful ageing (P > 0.05). Moderate physical activity had statistically significant effects on four components of successful aging, including major disease, physical function, life satisfaction, and social participation (P < 0.05).

CONCLUSION

Moderate-intensity physical activity was most beneficial to the successful ageing of the elderly and should be promoted in the elderly population.

Finding the Silver Lining: Aging Well Amongst Older Brazilian Women in the Post-Migration Context

STUDY BACKGROUND

The aging population in Canada has been increasing steadily over the past 40 years, however, there is limited information about the meaning of aging well amongst older Brazilian women in Canada.

METHODS

A Heideggerian interpretive phenomenology study was conducted to understand the meaning of aging well amongst older Brazilian women in the post-migration context living in the Greater Toronto Area (GTA) in Ontario, Canada.

RESULTS

Eight older Brazilian women residing in the GTA were recruited through purposive and snowball sampling and participated in individual face-to-face interviews. Through data analysis and the incorporation of Heidegger's four existentials of human existence, the themes that emerged were (a) Embracing being part of a mosaic, (b) Aging with grace, (c) Chasing your dreams and (d) Being a bridge and not a fence. The overarching theme was: Finding the silver lining: Aging well.

CONCLUSION

This study informs nursing practice, research and policy development to advance the health of older immigrant adults in Canada.

Successful aging and environmental factors in older individuals in urban and rural areas: A cross-sectional study

OBJECTIVE

The effects of the environmental factors on successful aging (SA) are not well understood. This study aimed to assess SA and related factors in older individuals in urban and rural areas, exploring differences between groups and investigating the effects of environmental factors.

METHODS

This was a cross-sectional study of 205 and 212 older people in urban and rural areas of Shandong Province, respectively, between March 2019 and September 2019. SA was measured using the Successful Aging Inventory (SAI). The environmental factors were assessed using the WHOQOL-100 scale. Univariable and multivariable analyses were performed to determine associations of different parameters with SA.

RESULTS

The scores of SA and environmental factors of older individuals in urban vs. rural areas were 48.79 vs. 46.14 and 128.63 vs. 107.81, respectively (both P < 0.05). All "Environment" dimensions ("Safety and physical security", "Home environment", "Financial resources", "Health and social care", "Opportunities for acquiring new information and skills", "Participation and opportunities for leisure", and "Transport"), except "Physical environment (pollution/noise/traffic/climate)", were associated with SA (all P < 0.05). Multiple linear regression showed that psychological resilience, physical activity, self-evaluation of SA, environment, social support, and hearing status were shared factors by the urban and rural older individuals.

CONCLUSION

The SA and environmental factor scores were higher in urban older individuals compared with rural ones. Environment dimensions (except "Physical environment (pollution/noise/traffic/climate)") were associated with SA.

Association Between Objectively Measured Physical Activity And Musculoskeletal Disorders, And Perceived Work Ability Among Adult, Middle-Aged And Older Women

Purpose

The purpose of this study was to assess the relationship between objectively measured physical activity and perceived work ability and musculoskeletal disorders among adult, middle-aged, and older women.

Patients and methods

This study used a cross-sectional design with a convenience sample of 348 women divided into 3 age groups: 30–49 years (n=111), 50–65 years (n=120), 66–75 years (n=117). Weekly physical activity was monitored using tri-axial accelerometer ActiGraph Gt3X. Perceived work ability was assessed using the standardized Work Ability Index (WAI) questionnaire. Information about the occurrence and intensity of musculoskeletal disorders was collected using standardized Nordic Musculoskeletal Questionnaire (NMQ) expanded by visual analog pain intensity scale (VAS).

Results

Regardless of age, women who met physical activity recommendations achieved higher scores in each part of the WAI, and also in the total WAI scores. However, the most significant differences were found in women aged 50–64 years, and included the following items: subjective work ability, work ability in relation to demands, work impairments, sick leave in the past year. Total WAI scores were also significantly higher in women aged 30–49 and 50–64 years who met PA recommendations in comparison to women who did not meet recommendations. Also, significant relations between the frequency of occurrence of musculoskeletal problems and meeting physical activity recommendations were found in women aged 50–64 years. Those who were more physically active reported less musculoskeletal problems in shoulders (p=0.006) and ankles/feet (p=0.018) regions.

Conclusion

Adherence to Global Recommendations on Physical Activity for Health disseminated by WHO is related to better-perceived work ability among adult (30–49 years) and middle-aged (50–64 years) women. There is also a relationship between adherence to recommendations of physical activity and frequency and intensity of musculoskeletal pain among middle-aged women.
