Associations Between Changes in Depression/Anxiety Symptoms and Fall Worry Among Community-Dwelling Older Adults

The mediating effect of life satisfaction between daily living abilities and depressive symptoms in the Chinese older people: evidence from CHARLS 2020

Background

Depressive symptoms represent a significant public health challenge, impacting the mental well-being of older adults. Despite this, the understanding of how activities of daily living (ADL) abilities correlate with life satisfaction and depressive symptoms among older Chinese adults remains limited.

Aims

This study aims to investigate the relationship between ADL and depressive symptoms in older people Chinese individuals, with a specific focus on examining the mediating role of life satisfaction within this context.

Methods

The study utilized data from the China Health and Retirement Longitudinal Study (CHARLS) collected in 2020. A cohort of 8,343 individuals aged 60 years and above was included. The analysis was conducted using STATA 17.0 and SPSS 26.0, employing descriptive statistics, chi-square tests, Pearson correlations, and mediation analysis using the percentile Bootstrap method with 5,000 resamples to explore the interrelations among ADL, life satisfaction, and depressive symptoms.

Results

ADL is positively correlated with life satisfaction (r = 0.129, p < 0.01) and negatively correlated with depressive symptoms (r = -0.313, p < 0.01). Additionally, life satisfaction and depressive symptoms are negatively correlated with each other (r = -0.360, p < 0.01). In the model of the mediating effect, ADL directly, significantly and negatively predicts depressive symptoms in the Chinese older people (β = -0.193, t = -17.827, p < 0.001). After incorporating life satisfaction into the regression equation, the direct predictive effect of ADL on depressive symptoms remains significant (β = -0.177, t = -17.099, p < 0.001); furthermore, ADL has a significant positive predictive effect on life satisfaction (β = 0.007, t = 4.959, p < 0.001) and life satisfaction significantly negatively predicts depressive symptoms (β = -2.235, t = -27.799, p < 0.001). Furthermore, the direct effect of ADL on depressive symptoms (-0.177) and its mediating effect (-0.016) account for 91.71% and 8.29% of the total effect (-0.193), respectively.

Conclusion

ADL is inversely associated with the risk of depressive symptoms among older people Chinese individuals, with life satisfaction serving as a significant mediator in this relationship. Interventions aimed at improving life satisfaction in older people individuals with ADL impairments may effectively reduce or prevent the onset of depressive symptoms.

Different neurocognitive controls modulate obstacle avoidance through pregnancy

Understanding why falls during pregnancy occur at over 25% rate over gestation has clinical impacts on the health of pregnant individuals. Attention, proprioception, and perception of the environment are required to prevent trips and falls. This research aimed to understand how the changes to these neurocognitive processes control obstacle avoidance through gestation. Seventeen pregnant participants were tested five times in 6-week intervals. Participants walked an obstacle course (OC), and we analyzed the crossings over obstacles that were set to 10% of participants' body height. Participants also performed an attentional network test (ANT: performance of specific components of attention), an obstacle perception task (OP: ability to visually define an obstacle and translate that to a body posture), and a joint position sense task (JPS: ability to recognize and recreate a joint position from somatosensation). In the OC task, average leading and trailing foot crossing heights significantly reduced by 13% and 23% respectively, with no change in variation, between weeks 13 and 31 of pregnancy, indicating an increased risk of obstacle contact during this time. The variability in minimum leading foot distances from the obstacle was correlated with all three neurocognition tasks (ANT, OP, and JPS). Increased fall rates in the second and third trimesters of pregnancy may be driven by changes in attention, with additional contributions of joint position sense and environmental perception at various stages of gestation. The results imply that a holistic examination on an individual basis may be required to determine individual trip risk and appropriate safety modifications.

The association between depressive symptoms with fear of falling and cognitive decline in older adults in the Korean community: An analysis of the Korean Longitudinal Study of Aging (KLoSA), 2006-2020

OBJECTIVES

This study aimed to investigate the effects of fear of falling (FOF) on cognitive decline in older adults in the Korean community, depending on the presence of accompanying depressive symptoms.

METHODS

A total of 6263 individuals were included in the final analysis. Based on their baseline evaluation results for depressive symptoms and FOF, the subjects were divided into four groups: "normal control" (NC, n = 3783), "depression only" (Dep-only, n = 291), "fear of falling only" (FOF-only, n = 1755), and "depression with fear of falling" (Dep-FOF, n = 434). Cognitive decline was defined as a loss of more than three points in the K-MMSE score in participants with at least two years of follow-up. We examined the association between FOF accompanied by depressive symptoms and cognitive decline using a multivariate Cox proportional hazard model.

RESULTS

Cognitive decline occurred in 76.3%, 68.5%, 63.9%, and 56.4% of the Dep-FOF, FOF-only, Dep-only, and NC groups, respectively. Our findings suggest that individuals with FOF do not always have cognitive decline (HR = 1.03, 95% CI = 0.95-1.12, P = 0.43) compared to individuals without FOF. Furthermore, depressive symptoms with FOF are associated with a higher risk of cognitive decline (HR = 1.23, 95% CI = 1.08-1.41, P = 0.002) in community-dwelling older adults in Korea.

CONCLUSION

Healthcare providers should be attentive to community-dwelling older adults who experience both depressive symptoms and FOF because our findings suggest that this unique combination increases the risk of cognitive decline.

Association Between Pain and Fall Worry Among Community-Dwelling Older People With Cognitive Impairment in the United States

Background and Objectives

Previous studies have found that pain is associated with fall worry among community-dwelling older people. However, both pain and fall worry are poorly understood and underaddressed among community-dwelling older people with cognitive impairment (CI). It is essential to examine the association between pain and fall worry, and how sociodemographic and health characteristics may shape fall worry among this subgroup.

Research Design and Methods

We used data from the 2015 National Health and Aging Trends Study (analytic sample: n = 1150 community-dwelling older people with CI; were self-interviewed; mean age: 81; age range: 65-107). The number of pain sites in the prior month was assessed by presenting a card listing common pain sites (eg, back, knees). Two questions assessed past-month fall worry, "did you worry about falling down" and "did this worry ever limit your activities." Following descriptive statistics, we fit multinomial logistic regression models to examine the associations between different pain characteristics (number of sites, severity, location) and non-activity-limiting and activity-limiting fall worry.

Results

Non-activity-limiting fall worry was endorsed by 21.1% and activity-limiting fall worry by 13.6% of community-dwelling older people with CI. After adjusting for sociodemographic characteristics and fall-worry-related covariates, multinomial logistic regression analysis found that a greater number of pain sites (relative risk ratio [RRR] = 1.22, 95% Confidence Interval [95% CI] = 1.12-1.33, p <.001) and severe pain (RRR = 2.05, 95% CI = 1.12-3.75, p = .020) was associated with activity-limiting fall worry. Both lower body (knee, foot, and leg) and upper body (hand, wrist, shoulder, neck, and stomach) pain were found to be associated with a high risk of activity-limiting fall worry.

Discussion and Implications

These findings suggest pain and fall worry are common among community-dwelling older people with CI and can be elicited directly from those who are communicative. Fall prevention for this population should prioritize pain management to mitigate activity-limiting fall worry because activity limitation increases the risk of falls.

Recurrent Falls over Three Years among Older Adults Age 70+: Associations with Physical and Mental Health Status, Exercise, and Hospital Stay

We used the 2019-2021 U.S. National Health and Aging Trend Study (N = 3,063, age 70+) and multinomial logistic regression and generalized linear models with Poisson and log link to identify correlates of (1) recurrent falls (2 + falls) over 3 years (2019-2021); and (2) any subsequent fall among those who had a fall in 2019. We also examined the associations between falls and hospitalization in 2021. Results show that those with recurrent falls had greater physical/functional and psychological health problems in 2019, while single fallers over the 3 years were not significantly different from those without a fall. Exercise was associated with a lower likelihood of a subsequent fall among those who fell in 2019. Both a single fall and recurrent falls over the 3 years were associated with a higher risk of hospitalization in 2021. Multifactorial fall preventions including exercise and depression/anxiety treatment are needed to mitigate recurrent fall risks.
