Successful Present, Successful Future? Assessment of a Nonbinary Model of Successful Aging

The Relationship Between Successful Aging and All-Cause Mortality Risk in Older Adults: A Systematic Review and Meta-Analysis of Cohort Studies

Background

This meta-analysis aimed to explore the effect of successful aging (SA) on all-cause mortality risk in older people to provide a theoretical basis for promoting SA.

Methods

PubMed, Embase, CINAHL, CNKI, and WanFang databases (inception to March 4, 2021) were searched for cohort studies to evaluate the relationship between SA and mortality in older people. A random-effects model was used to synthesis hazard ratio and 95% confidence intervals. Quality assessment was performed using the Newcastle–Ottawa scale. All statistical analyses were conducted in STATA 16.0.

Results

In total, 21,158 older adults from 10 studies were included in the current systematic review and meta-analysis. The SA group tended to have 50% lower risk of all-cause mortality than the non-SA group (pooled hazard ratio = 0.50, 95% confidence intervals: 0.35–0.65, P < 0.001; I² = 58.3%). The risk of all-cause mortality in older people increased by 17% for each unit increment in the healthy aging index (HAI) (I² = 0%, P = 0.964). Compared with the reference group (HAI 0-2), older people with HAI 3-4, HAI 5-6, and HAI 7-10 had 1.31-fold, 1.73-fold, and 2.58-fold greater risk of all-cause mortality, respectively. Subgroup analysis did not reveal possible sources of heterogeneity.

Conclusions

This meta-analysis suggests that older adults with SA reduced the risk of all-cause mortality by 50%. However, few interventional studies have been conducted. Therefore, healthcare providers must be aware of the relationship between SA and mortality risk and actively develop intervention methods for helping old people achieve SA.

Convivir (to Coexist) and Other Insights: Results From the Positive Aging for Latinos Study

Many Latinos in the United States do not have access to culturally sensitive services to help them age well. We combined community-based participatory research with concept mapping methods to understand how a sample of community-dwelling Latino older adults view positive aging. Nine focus groups (N = 101) generated 85 non-repeating statements, which were used to produce a final map with 11 clusters, organized into four overarching regions: Convivir (To Coexist), Self-Sufficiency, Perspectives on Life, and Healthy Behaviors. Further analyses revealed three themes: (1) the importance of varied social connections, as conveyed by the region labeled Convivir; (2) a multifaceted understanding of "stability" that includes finances, relationships, and spirituality; and (3) the need for a mature mindset reflected in the thematic cluster Tomalo Suave (Take It Easy). Findings can inform the development of interventions for Latino older adults and the cultural adaptation of programs initially designed for non-Latinos.

Active Ageing across the Life Course: Towards a Comprehensive Approach to Prevention

"Active ageing" has become the leading scientific and policy conceptualization of a later life over the past two decades in the European Union (EU). It has been used as a key strategy for responding to demographic ageing. In the United States, in contrast, discourses around successful ageing have been more prevalent. This review article charts the development of active ageing responses to demographic change, showing how the concept compares with the notion of successful ageing and other terms associated with "ageing well." It identifies how, in practice, active ageing has been dominated by a narrow economic or productivist interpretation that prioritizes the extension of working life (to reduce the "burden" of population ageing). Such interpretations of active ageing undermine its value and emphasize the need for a more comprehensive approach which is set out. The development of the Active Ageing Index in 2012 provided a new analytical tool to promote evidence-based strategies towards population ageing. However, in practice, we show how it has not yet engaged fully with a comprehensive approach to active ageing or with the critical role of the life course in shaping the experience of old age. Nonetheless, this review article shows that the concept of active ageing still has an important role to play in our understanding of and responses to population ageing.

Cross-cultural adaptation and psychometric properties of the Brazilian Portuguese version of successful aging scale in community-dwelling older adults

There is a growing consensus regarding the multidimensional nature of successful aging (SA), including both the biomedical and psychosocial domains of the aging process. The Successful Aging Scale (SAS) is a self-rated instrument addressing both of these components. The aim of this study was to analyze the psychometric properties of the Brazilian Portuguese version of the SAS (SAS-B) with regard to reliability and validity in 949 Brazilian community-dwelling older adults (53.60% women; M = 69.49 years; standard deviation = 7.67). Confirmatory factorial analysis (CFA) was performed to provide evidence on its structural validity. Convergent and divergent validity was studied by means of examining the relationships of SAS-B with scales concerning resilience, life satisfaction, self-esteem, social support, perceived stress, and health, as well as mental health. The CFA showed that the SAS-B is multidimensional with three correlated factors (χ² /df = 2.74; standardized root mean square residual = 0.03; root mean square error approximation = 0.04; comparative fit index = 0.91), and its factors showed adequate reliability (ω = 0.70 for Healthy living habits, ω = 0.69 for Adaptive coping, and ω = 0.70 for Engagement with Life). Convergent and divergent validity was endorsed by correlations with related factors. The SAS-B is a reliable and valid self-rated instrument to measure the SA from a multidimensional perspective.

Definitions of successful ageing: a brief review of a multidimensional concept

Successful ageing has become an important concept to describe the quality of ageing. It is a multidimensional concept, and the main focus is how to expand functional years in a later life span. The concept has developed from a biomedical approach to a wider understanding of social and psychological adaptation processes in later life. However, a standard definition of successful ageing remains unclear and various operational definitions of concept have been used in various studies. In this review we will describe some definitions and operational indicators of successful ageing with a multidimensional approach. (www.actabiomedica.it)

Midlife predictors of active and healthy aging (AHA) among older businessmen

Background

Active and healthy aging (AHA) is an important phenomenon in aging societies.

Aims

Our aim was to investigate midlife predictors of AHA in a socioeconomically homogenous male cohort.

Methods

In 2010, AHA was defined in the Helsinki Businessmen Study (men born in 1919–1934) with six criteria: (1) being alive, (2) responding to the mailed survey, (3) no reported cognitive problems, (4) feeling of happiness, (5) no difficulties in activities of daily living (ADL), and (6) no significant chronic diseases. Midlife factors were assessed in 1974 (n = 1759, mean age 47 years). Of the survivors in 2010 (n = 839), 10.0% (n = 84) fulfilled all AHA criteria, whilst 13.7% (n = 115) had chronic diseases but fulfilled other five criteria. Midlife predictors of AHA were analyzed with logistic models.

Results

Of the midlife factors, smoking [Odds ratio (OR) 0.44, 95% confidence interval (CI) 0.25–0.77], higher body mass index (BMI) (OR 0.75, 0.59–0.96), and higher total cholesterol (OR 0.76, 0.60–0.97) prevented significantly full AHA criteria, whereas higher self-rated health (SRH) (OR 1.73, 1.07–2.80) predicted significantly of fulfilling all AHA criteria. Midlife smoking (OR 0.87, 0.84–0.91), higher BMI (OR 0.73, 0.61–0.86), and higher alcohol consumption (OR 0.73, 0.60–0.90) prevented significantly of fulfilling the five AHA criteria with chronic diseases, and higher SRH (OR 1.90, 1.37–2.63) predicted significantly the five AHA criteria (chronic diseases present).

Discussion

Our study suggests that midlife factors, especially good SRH and low levels of cardiovascular risk factors, are associated with AHA.

Conclusions

The study emphasizes the importance of life-course predictors of healthy aging.

What Is Successful Aging? A Psychometric Validation Study of Different Construct Definitions

Background and Objectives

We examined the validity of 5 successful aging (SA) operationalizations that assessed different facets of the SA construct (cognitive and physical health and disability; well-being; social engagement).

Research Design and Methods

A total of 2,478 participants (mean age = 82.5 years, standard deviation [SD] = 3.47) were studied. We used confirmatory factor analysis to investigate the relationships between facets and to determine the convergent validity as well as short-term (1.5 years) and long-term (4.5 years) predictive validity of the 5 SA operationalizations for measures of quality of life (QoL) and objective health outcomes.

Results

A general SA operationalization that included all SA facets but also allowed differences between them showed the best model fit and construct validity. A biomedical operationalization of SA that excluded either the well-being or the social engagement facet showed lower convergent and predictive validity for subjective measures (e.g., QoL) but higher associations with objective measures (e.g., health). A purely psychosocial SA operationalization that excluded the physiological facet did not allow good prediction of objective health outcomes.

Discussion and Implications

Our results suggest that a well-balanced SA operationalization should include measures assessing health, disability, well-being, and social engagement.
