Falls Are Associated With Decreased Autonomy, and Self-Efficacy Moderates This Relation: Results From a National Study

Association Between Falls and Social Frailty in Community-Dwelling Older Japanese Adults

OBJECTIVES

This study aimed to investigate the association between falls and social frailty and its components among older Japanese adults.

METHODS

This is a cross-sectional study. Participants were categorized into 3 groups based on the number of falls in the past year: no fall (none), a single fall (occasional), and more than one fall (recurrent). The participants who met 2 or more of the following criteria were defined as socially frail: living alone, going out less frequently compared with the previous year, rarely visiting friends, feeling unhelpful to friends or family, and not talking with someone daily.

RESULTS

A total of 4,495 older Japanese adults living in a community analyzed in this study (51.0% women). Of the participants in this study, 3,851 (85.7%) were categorized as none, 443 (9.9%) as occasional, and 201 (4.5%) as recurrent. The proportion of participants considered socially frail was 11.5% in this study. Recurrent falls were associated with social frailty, even after adjusting for covariates (odds ratio [OR]: 1.49; 95% confidence interval [CI]: 1.01-2.19). The experience of recurrent falls was associated with the following components: "feeling unhelpful to friends and family" (OR: 1.62; 95% CI: 1.14-2.31) and "going outside less frequently compared with last year" (OR: 1.57; 95% CI: 1.06-2.31).

DISCUSSION

Among older Japanese adults, recurrent falls were associated with social frailty and with 2 of its components in particular: social roles and social participation. Future longitudinal studies should be conducted to gain insight into any causal relationships between these variables.

Delirium in Head Trauma: Looking for a Culprit

Head trauma and delirium are two common conditions in the elderly population. They both carry a heavy burden in terms of mortality and morbidity and are associated with one another through several environmental and clinical factors, such as comorbidities, age, and sex. One factor that may play a role in both these conditions is inflammation, which might also represent a link between them. In particular, head trauma can cause both systemic and neuroinflammation, while delirium appears to be precipitated by inflammatory conditions, while also involving a number of inflammatory pathways in its pathogenesis. Interleukin 6 and tumor necrosis factor α are only two of the main actors in this crosstalk, which also involves microglia and immune cells. An indirect proof is that anti-inflammatory drugs have proven effective in reducing post-traumatic delirium, thus demonstrating the importance of inflammation in the pathophysiology of this disease. In this paper, we have revised the available literature exploring the links between inflammation, head trauma and delirium and we will discuss the mechanisms of this relationship, paying particular attention to the possible future implications.

Evaluation of therapy in traumatic elderly falls to return autonomy and functional status

Background

Traumatic falls among the elderly (≥ 65 years old) are the leading cause of injury, morbidity and mortality are increasing with rising medical costs.

Methods

This is a retrospective medical record review of elderly mechanical fall patients (288 patients) admitted to an American College of Surgeons level II trauma center from January 2016 to January 2021. Demographics and comorbidities were determined, and physical/occupational therapy used to predict subsequent fall readmissions.

Results

Out of 288 patients, 243 received therapy with 45 readmissions for subsequent falls. Age (P = .016), body mass index (P = .035), previous falls (P = .003), walker/cane use (P = .039), and dementia (P = .038) were predictive of readmission. Therapy was shown to benefit patients, but deferred therapy sessions were shown to be associated with prolonged hospitalization.

Conclusion

Directed therapy may improve functionality and return autonomy to elderly mechanical fall patients admitted to trauma services.

•

Elderly fall patient evaluation after falls can predict need for therapy.

•

Directed therapy can benefit and potentially prevent recurrence of falls.

•

Deferrals of therapy are associated with prolonged hospital stays.

Use and effect of embodied conversational agents for improving eating behavior and decreasing loneliness among community-dwelling older adults: A randomized controlled trial (Preprint)

Background

Embodied conversational agents (ECAs) have been proposed as a promising interaction modality for the delivery of programs focused on promoting lifestyle changes. However, it is not understood what factors influence the health effects of ECAs or their use.

Objective

We aimed to (1) identify whether ECAs could persuade community-dwelling older adults to change their dietary behavior and whether ECA use could decrease loneliness, (2) test the pathways to these effects, and (3) understand factors influencing the use of ECAs.

Methods

A randomized controlled trial was conducted. The intervention group received access to the PACO service for 8 weeks. The waitlist group started PACO use after waiting for 4 weeks. Two primary outcomes (eating behavior and loneliness) were assessed via online questionnaires at intake, upon joining the waitlist, after 4 weeks, and after 8 weeks. The third primary outcome (use) was assessed via data logs. Secondary outcomes were measured at the same time points, via questionnaires or an optional interview.

Results

In total, 32 participants completed the intervention. We found a significant correlation between use in minutes on the one hand, and perceived usefulness (r=0.39, P=.03) and enjoyment on the other (r=0.38, P=.03). However, these did not predict use in the full regression model (F_2,29=1.98, P=.16, R²=0.12). Additionally, PACO use did not lead to improvement in eating behavior (χ²₂=0.34, P=.85) or a decrease in loneliness (χ²₂=0.02, P=.99).

Conclusions

Our study did not provide any concluding evidence about factors that are linked to the use or health effects of ECAs. Future service design could benefit from either creating a functional design catering to the predominant stage in the precaution adoption process model of the targeted population, or by personalizing the service based on an intake in which the end user’s stage is determined.

Use and Effect of Web-Based Embodied Conversational Agents for Improving Eating Behavior and Decreasing Loneliness Among Community-Dwelling Older Adults: Protocol for a Randomized Controlled Trial

BACKGROUND

An unhealthy eating pattern and loneliness negatively influence quality of life in older age. Embodied conversational agents (ECAs) are a promising way to address these health behaviors in an engaging manner.

OBJECTIVE

We aim to (1) identify whether ECAs can persuade community-dwelling older adults to change their dietary behavior and whether ECA use can decrease loneliness, (2) test these pathways to effects, and (3) understand the use of an ECA.

METHODS

The web-based eHealth app PACO is a fully automated 8-week intervention in which 2 ECAs engage older adults in dialogue to motivate them to change their dietary behavior and decrease their loneliness. PACO was developed via a human-centered and stakeholder-inclusive design approach and incorporates Self-determination Theory and various behavior change techniques. For this study, an unblinded randomized controlled trial will be performed. There will be 2 cohorts, with 30 participants per cohort. Participants in the first cohort will immediately receive the PACO app for 8 weeks, while participants in the second cohort receive the PACO app after a waiting-list condition of 4 weeks. Participants will be recruited via social media, an online panel, flyers, and advertorials. To be eligible, participants must be at least 65 years of age, must not be in paid employment, and must live alone independently at home. Primary outcomes will be self-assessed via online questionnaires at intake, control, after 4 weeks, and after 8 weeks, and will include eating behavior and loneliness. In addition, the primary outcome-use-will be measured via data logs. Secondary outcomes will be measured at the same junctures, via either validated, self-assessed, online questionnaires or an optional interview.

RESULTS

As of July 2020, we have begun recruiting participants.

CONCLUSIONS

By unraveling the mechanisms behind the use of a web-based intervention with ECAs, we hope to gain a fine-grained understanding of both the effectiveness and the use of ECAs in the health context.

The Onset of Falls Reduces Subjective Well-Being. Findings of a Nationally Representative Longitudinal Study

Introduction: The prevalence of older individuals experiencing a fall is high. Moreover, falls can have deleterious effects on health status. Additionally, falls can affect the subjective well-being of individuals. However, there is a lack of studies examining the link between falls and subjective well-being. Therefore, the objective of this study was to investigate whether the onset of falling is associated with (intraindividual) decreases in subjective well-being in men and women. Materials and Methods: Longitudinal data (from wave 5 to wave 6) were taken from a population-based sample of individuals residing in private households in Germany [in our analytical sample: 3,906 observations (men), and 3,718 observations (women)]. Positive and negative affect were quantified using the Positive and Negative Affect Schedule (PANAS). Life satisfaction was assessed using the Satisfaction with Life Scale (SWLS). Results: Adjusting for various potential confounders, fixed effects regressions showed that the onset of falls was associated with a decrease in positive affect (β = 0.08, p < 0.01), and an increase in negative affect (β = 0.07, p < 0.01) among men. While the onset of falls was not associated with changes in positive affect in women, it was associated with a decrease in negative affect in women (β = 0.06, p < 0.05). Sex differences were significant. The onset of falls was not associated with decreases in life satisfaction in men, nor in women. Discussion: The present study particularly highlights the link between the onset of falls and reduced affective well-being among men. Avoiding falls may contribute to maintaining affective well-being among middle-aged and older men.

What are the psychosocial consequences when fear of falling starts or ends? Evidence from an asymmetric fixed effects analysis based on longitudinal data from the general population

OBJECTIVES

The purpose of this study was to identify whether the onset and the end of fear of falling (FOF) are associated with psychosocial consequences (in terms of depressive symptoms, loneliness, social isolation, autonomy, and subjective well-being).

METHODS/DESIGN

Longitudinal data for this study were taken from the nationally representative German Ageing Survey which included community-dwelling individuals ≥40 years (wave 5 and wave 6). Psychosocial outcome measures were assessed using widely established and well-validated scales. The presence of FOF was used as the main explanatory variable. It was adjusted for age, family status, labor force participation, self-rated health, physical functioning, as well as the number of chronic conditions.

RESULTS

Linear fixed effects regressions revealed that FOF was associated with adverse psychosocial outcomes (increased depressive symptoms, lower life satisfaction, lower positive affect, higher negative affect, and lower perceived autonomy). Asymmetric fixed effects regressions analysis showed that the onset of FOF was associated with reduced life satisfaction as well as reduced autonomy, whereas the end of FOF was associated with reduced depressive symptoms, decreased loneliness scores, as well as decreased negative affect.

CONCLUSIONS

The study findings suggest that future studies should analyze the consequences of FOF differently (onset and end of FOF) which has practical important implications. More specifically, while strategies to avoid the onset of FOF may help to maintain satisfaction with life and autonomy, strategies to end FOF may contribute to avoid increased loneliness, feelings of negative affect, as well as increased depressive symptoms.

Dual sensory impairment and psychosocial factors. Findings based on a nationally representative sample

BACKGROUND

A considerable proportion of individuals in late life experience dual sensory impairment (DSI), which can be defined as the combined presence of hearing and visual problems. However, there is little knowledge regarding the psychosocial correlates of DSI. Consequently, our objective of this study was to identify the link between DSI and psychosocial factors in middle-aged and older adults.

METHODS

Data were used from the sixth wave of the nationally representative German Ageing Survey. Individuals were classified as dual sensory impaired when both visual and hearing impairments existed. As psychosocial correlates, we included life satisfaction, positive affect, negative affect, depressive symptoms, loneliness, social isolation, self-esteem and autonomy. Outcome measures were quantified using widely established scales. In our analytical sample, there were 5138 observations.

RESULTS

Bivariate analysis showed that, compared to individuals with no sensory impairment, individuals with DSI had markedly worse psychosocial factors (in terms of life satisfaction, positive affect, negative affect, depressive symptoms, loneliness, social isolation, self-esteem and autonomy). Adjusting for various covariates, regression analysis showed that individuals with DSI consistently experienced worse psychosocial factors compared to individuals with no sensory impairment.

CONCLUSION

Our current study stressed the cross-sectional association between DSI and worse psychosocial factors. Longitudinal studies are needed to confirm our findings.

The link between falls, social isolation and loneliness: A systematic review

BACKGROUND

The chances of experiencing a fall among those aged 60 years and older increase as risk factors accumulate. In the last few decades, several studies have identified different risk factors for falls in older people, including the role of social isolation and loneliness. This systematic review provides an overview of published literature that analyzes the bidirectional relation between falls and social isolation or loneliness.

MATERIAL AND METHODS

Two databases (PubMed and Europe PMC) were used to search for publications investigating the relationship between falls, social isolation and/or loneliness in older people. Similar articles and references were screened against the inclusion criteria.

RESULTS

17 studies met the inclusion criteria and were included. Only a few studies assessed the association between falls and social isolation/loneliness among older people. Therefore, articles examining the association between falls and living alone status among people aged 60 and older were included as well. In all studies loneliness, social isolation, and living alone were significantly associated with falls in older people.

CONCLUSIONS

The findings emphasize the importance of the relationship between falls and social isolation, loneliness and living alone among older people. As there are only a few studies assessing the relationship between falls and loneliness or social isolation, further research in this field should be conducted. In particular, longitudinal studies that utilize standardized measurement instruments should be carried out.
