Factors influencing the stages of frailty among Korean older adults focusing on objective and subjective social isolation

Associations of social engagement and loneliness with the progression and reversal of frailty: longitudinal investigations of 2 prospective cohorts from the UK and the USA

Social connections may impact the dynamic trajectory of frailty. Using data from the British Regional Heart Study (BRHS) in the UK (n = 715) and the US Health, Aging and Body Composition (Health ABC) Study (n = 1256), we conducted multinominal regression analyses to examine the association of baseline and change in social engagement and loneliness with progression to prefrailty and frailty, as well as their association with reversal to prefrailty and robust status among older adults. A higher level of social engagement at baseline (BRHS: relative risk ratio [RRR] 0.69 [95% CI, 0.55-0.85]; Health ABC: 0.56 [0.45-0.70]) and an increase in social engagement (BRHS: 0.73 [0.59-0.90]; Health ABC: 0.51 [0.41-0.63]) were associated with a lower risk of developing frailty. In BRHS, a higher level of loneliness at baseline (1.42 [1.10-1.83]) and an increase in loneliness (1.50 [1.18-1.90]) raised the risk of developing frailty. For reversal of frailty, higher social engagement at baseline (Health ABC: 1.63 [1.08-2.47]) and an increase in social engagement (BRHS: 1.74 [1.18-2.50]; Health ABC: 1.79 [1.17-.274]) were beneficial. Social connections may be potentially important and modifiable factors in both preventing and reversing progression of frailty in older adults.

Independent and combined associations of depression and cognitive impairment with frailty in oldest-old adults

BACKGROUND

Frailty is one of the most significant issues related to human aging. Although studies have confirmed the association of mental and cognitive disorders with frailty, the association might be influenced by age, since oldest-old adults are more likely to have adverse health outcomes. Thus, this study aimed to examine independent and combined associations of mental health and cognitive function with frailty in oldest-old adults using data from the Chinese Longitudinal Healthy Longevity Survey in 2018.

METHODS

A sum of 6,891 and 3,171 older adults aged 80 and older were included in this study when analyzing the association of depression and cognitive impairment with frailty, respectively. Frailty was measured by the Study of Osteoporotic Fractures frailty index, depression was assessed by the Center for Epidemiologic Studies Depression Scale, and cognitive impairment was evaluated by the Chinese version of modified Mini-Mental State Examination. Independent sample t-test, Chi-square tests, and logistic regression analyses were used to examine the associations of depression and cognitive impairment with frailty.

RESULTS

Older persons with depression or cognitive impairment had a higher chance of frailty. The adjusted odds ratio (OR) of frailty was 1.27 (95% CI: 1.01, 1.59, p = 0.044) in those with depression, and 1.85 (95% CI: 1.14, 3.01, p = 0.013) in those with cognitive impairment. Compared to adults who had neither depression nor cognitive impairment, those with either depression or cognitive impairment, and those with both depression and cognitive impairment had a significantly higher likelihood of frailty (adjusted OR: 1.61, 95% CI: 1.07, 2.41; and adjusted OR: 4.03, 95% CI: 2.05, 7.94).

CONCLUSIONS

The findings suggest that depression and cognitive impairment are associated with frailty. The concurrence of depression and cognitive impairment has an additive effect on frailty in oldest-old population.

Exploring the Role of Social Factors in Cognitive Frailty among South Korean Older Adults

Cognitive frailty, which is characterized by the co-occurrence of physical frailty and cognitive impairment, poses significant risks to the well-being and independence of elderly individuals. Previous research has established that demographic, health-related, and social factors contribute to both physical frailty and cognitive decline. However, the role of social factors in influencing cognitive frailty remains unclear. This study aims to identify the relationship between social factors and cognitive frailty among Korean older adults living in the community. We performed secondary analyses of data from the 2020 Survey on Older Adults. After entering demographic factors and health-related factors into the logistic model as covariates, this study explored the association between cognitive frailty and social factors, including living arrangements, social support, the frequency of engagement in social activities per week, and satisfaction with friends and community. Among participants, approximately 2.9% had cognitive frailty, 3.2% had only physical frailty, and 21.9% had only cognitive decline. Lower levels of satisfaction with friends and the community and infrequent participation in social activities were strongly correlated with cognitive frailty. These findings emphasize the necessity of public health programs that encourage older individuals' social involvement. A supportive social environment can be fostered through initiatives that promote community events, group activities, and volunteerism. Public health policies should prioritize the development and maintenance of social activity centers that offer various programs to prevent progression to cognitive frailty in older adults.

The relationship between frailty and social vulnerability: a systematic review

Both frailty (reduced physiological reserve) and social vulnerability (scarcity of adequate social connections, support, or interaction) become more common as people age and are associated with adverse consequences. Analyses of the relationships between these constructs can be limited by the wide range of measures used to assess them. In this systematic review, we synthesised 130 observational studies assessing the association between frailty and social vulnerability, the bidirectional longitudinal relationships between constructs, and their joint associations with adverse health outcomes. Frailty, across assessment type, was associated with increased loneliness and social isolation, perceived inadequacy of social support, and reduced social participation. Each of these social vulnerability components was also associated with more rapid progression of frailty and lower odds of improvement compared with the absence of that social vulnerability component (eg, more rapid frailty progression in people with social isolation vs those who were not socially isolated). Combinations of frailty and social vulnerability were associated with increased mortality, decline in physical function, and cognitive impairment. Clinical and public health measures targeting frailty or social vulnerability should, therefore, account for both frailty and social vulnerability.

The role of frailty, social networks, and depression in self-neglect in an older Chinese population: A cross-sectional descriptive study

OBJECTIVES

To identify the role of frailty, social networks, and depression in self-neglect in an older Chinese population.

METHODS

The study was conducted in 521 older adults recruited from four community healthcare centers in a district in Beijing, China. Participants were investigated by a set of questionnaires.

RESULTS

Frailty (β=0.150, p=0.759) was not associated with self-neglect of older adults. Social isolation (β=1.980, p<0.001) and depression (β=3.606, p<0.001) were both factors associated with self-neglect in older adults.

CONCLUSION

Management of depression and improvement of social networks of older adults should be incorporated into interventional strategies to effectively control self-neglect. Understanding self-neglect and its associated factors will ultimately contribute to the intervention development and well-being of older adults.
