Incidence Rates of Disability and Its Associated Factors among Korean Community-Dwelling Older Adults

Background: We aimed to identify incidence rates of disability and its associated factors among Korean community-dwelling older adults. Methods: The sample included 1,739 Koreans aged over 65 yr from the Korean Longitudinal Study of Aging (2006-2016) who reported no limitations in activities of daily living (ADL) or instrumental activities of daily living (IADL) at baseline (2006) and had complete data for other covariates. ADL, IADL, socio-demographic, lifestyle, and health-condition data were collected and analyzed using multiple logistic regression models. Results: The 10-yr incidence rates of ADL and IADL disability in subjects with no disability at baseline were 11.6% and 21.6%, respectively. After adjusting for socio-demographic, lifestyle, and health-condition factors, the incidence of ADL disability was higher in women (odds ratio [OR] =1.418, 95% confidence interval [CI]=1.102- 2.613) and increased with age (OR=1.170, 95% CI=1.133-1.208), multi-morbidity (OR=1.194, 95% CI=1.015- 1.406), and obesity (OR=1.563, 95% CI=1.057-2.311). It decreased in subjects living alone (OR=0.531, 95% CI=0.328-0.856). The incidence of IADL disability increased with age (OR=1.131, 95% CI=1.102-1.161), multimorbidity (OR=1.199, 95% CI=1.054-1.365), and cognitive disability (OR=1.422, 95% CI=1.083-1.866) and decreased for subjects living alone (OR=0.484, 95% CI=0.328-0.715) and with overweight (OR=0.725, 95% CI=0.532-0.988). Conclusion: Incidence rates of disability differed considerably based on socio-demographic, lifestyle, and health-condition factors. These results suggest the importance of identifying factors that can decrease the risk of disability in this group and of prevention efforts in populations with a higher disability risk.

Background:This cross-sectional study was performed to examine associations of objectively measured sedentary time (ST) and breaks in sedentary time (BST) with instrumental activities of daily living (IADL) disability in Japanese community-dwelling older adults.Methods:The sample comprised 1634 older adults (mean age: 73.3 y, men: 38.4%). Sedentary behavior was measured using a triaxial accelerometer. Disability was defined as inability in at least 1 of the IADL tasks using the Tokyo Metropolitan Institute of Gerontology Index of Competence.Results:After adjusting for potential confounders and moderate-to-vigorous physical activity (MVPA), longer ST was significantly associated with higher likelihood of IADL disability, whereas a greater number of BST was associated with lower likelihood of IADL disability. ST and BST remained statistically significant after mutual adjustment with odds ratio of 1.30 (95% confidence interval [CI)], 1.00–1.70) and 0.80 (95% CI, 0.65–0.99), respectively.Conclusions:This study first demonstrated that shorter ST and more BST were associated with lower risk of IADL disability independent of MVPA and that the association for ST was independent of BST and vice versa. These findings suggest not only total ST but also the manner in which it is accumulated may contribute to the maintenance of functional independence in older adults.

Aspirin Group

Abstract Background Cerebrovascular events, dementia and cancer can contribute to physical disability with activities of daily living (ADL). It is unclear whether low-dose aspirin reduces this burden in aging populations. In a secondary analysis, we now examine aspirin’s effects on incident and persistent ADL disability within a primary prevention aspirin trial in community-dwelling older adults. Methods The ASPREE (ASPirin in Reducing Events in the Elderly) trial of daily 100mg aspirin versus placebo recruited 19,114 healthy adults aged 70+ years (65+ years if U.S. minority) in Australia and the U.S. Six basic ADLs were assessed every six months. Incident ADL disability was defined as inability or severe difficulty with ≥1 ADL; persistence was confirmed if the same ADL disability remained after six months. Proportional hazards modelling compared time to incident or persistent ADL disability for aspirin versus placebo; death without prior disability was a competing risk. Results Over a median 4.7 years, incident ADL disability was similar in those receiving aspirin (776/9525) and placebo (787/9589) with walking, bathing, dressing and transferring the most commonly reported. Only 24% of incident ADL disability progressed to persistent. Persistent ADL disability was lower in the aspirin group (4.3 versus 5.3 events/1000py; HR=0.81, 95% CI:0.66-1.00), with bathing and dressing the most common ADL disabilities in both groups. Following persistent ADL disability there were more deaths in the aspirin group (24 versus 12). Discussion Low-dose aspirin in initially healthy older people did not reduce risk of incident ADL disability, although there was evidence of reduced persistent ADL disability.

Learning Trials

Abstract Objective Object location learning and memory may be important for older adults to successfully complete some everyday activities. Method This cross-sectional, correlational study investigated the ecological relevance of the Location Learning Test-Revised (LLT-R) in 195 community-dwelling, older adults in Western Australia. The LLT-R assesses object location learning and memory for everyday objects over five learning trials and after a 30-min delay. Knowledgeable informants provided structured ratings of participants’ activities of daily living and memory symptoms. Results A greater number of errors on LLT-R total learning trials were associated with mild problems in activities of daily living (particularly in travel and household domains), but not with memory symptoms. The LLT-R’s association with activities of daily living was accompanied by a small-to-medium effect size and was not better explained by demographics, global cognitive functioning, mood, or chronic medical conditions. Conclusions Findings provide some support for the ecological relevance of the LLT-R among older community-dwelling adults and suggest that object location learning may play a role in some everyday functioning problems that accompany typical aging.
