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 100 mg aspirin versus placebo recruited 19 114 healthy adults aged 70+ years (65+ years if U.S. minority) in Australia and the United States. Six basic ADLs were assessed every 6 months. Incident ADL disability was defined as inability or severe difficulty with ≥1 ADL; persistence was confirmed if the same ADL disability remained after 6 months. Proportional hazards modeling compared time to incident or persistent ADL disability for aspirin versus placebo; death without prior disability was a competing risk.Results: Over a median of 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 vs 5.3 events/1000 py; hazard ratio [HR] = 0.81, 95% confidence interval [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 vs 12).Discussion: Low-dose aspirin in initially healthy older people did not reduce the risk of incident ADL disability, although there was evidence of reduced persistent ADL disability.

Background: There are no primary prevention trials of aspirin with relevant geriatric outcomes in elderly people. ASPirin in Reducing Events in the Elderly (ASPREE) is a placebo-controlled trial of low-dose aspirin that will determine whether 5 years of daily 100-mg enteric-coated aspirin extends disability-free and dementia-free life in a healthy elderly population and whether these benefits outweigh the risks.Methods: Set in primary care, this randomized double-blind placebo-controlled trial has a composite primary endpoint of death, incident dementia or persistent physical disability. Participants aged 70+ years (non-minorities) or 65+ years (U.S. minorities) were free of cardiovascular disease, dementia, or physical disability and without a contraindication to, or indication for, aspirin. Baseline data include physical and lifestyle, personal and family medical history, hemoglobin, fasting glucose, creatinine, lipid panel, urinary albumin:creatinine ratio, cognition (3MS, HVLT-R, COWAT, SDMT), mood (CES-D-10), physical function (gait speed, grip strength), Katz activities of daily living and quality of life (SF-12).Results: Recruitment ended in December 2014 with 16,703 Australian and 2,411 U.S. participants, a median age of 74 (range 65-98) years and 56% women. Approximately 55% of the U.S. cohort were from minority groups; 9% of the total cohort. Proportions with hypertension, overweight, and chronic kidney disease were similar to age-matched populations from both countries although lower percentages had diabetes, dyslipidemia, and osteoarthritis.Discussion: Findings from ASPREE will be generalizable to a healthier older population in both countries and will assess whether the broad benefits of daily low-dose aspirin in prolonging independent life outweigh the risks.

Objective: To test the hypothesis that urinary incontinence (UI) is associated with incident parkinsonism in older adults.Methods: We used data from 2,617 older persons without dementia. Assessment included baseline self-report UI and annual structured exam which assessed parkinsonian signs, motor performances, cognitive function, and self-report disabilities. We used a series of Cox proportional hazards models to examine the association of UI with parkinsonism and adverse health outcomes and a mixed-effect model to examine the association of UI with the annual rate of cognitive decline. In decedents, regression models were used to examine if UI proximate to death was related to postmortem indices of neuropathologies.Results: At baseline, more than 45% of participants reported some degree of UI. Over an average of nearly 8 years of follow-up, UI was associated with incident parkinsonism (hazard ratio [HR] = 1.07, 95% CI = 1.02, 1.12), death (HR = 1.07, 95% CI = 1.03, 1.11), incident ADL disability (HR = 1.11, 95% CI = 1.07, 1.16), and incident mobility disability (HR = 1.07, 95% CI = 1.02, 1.13). UI was not related to incident MCI (HR = 1.02, 95% CI = 0.97, 1.07), incident AD dementia (HR = 1.00, 95% CI = 0.95, 1.05) or to the rate of cognitive decline (Estimate = -.002, standard error = .002, p = .167). In 1,024 decedents with brain autopsy, UI proximate to death was related to PD pathology (Lewy body pathology and nigral neuronal loss), but not Alzheimer's disease pathology or other age-related neuropathologies.Conclusion: UI in older adults is associated with incident parkinsonism and may identify older adults at risk for accumulating PD brain pathology.

Background. Identifying mobility disability risk factors may facilitate development of interventions promoting functional independence in older persons. We tested the hypothesis that musculoskeletal pain is associated with first occurrence of severe mobility disability. Methods. In a prospective observational study at 40 community-based sites, 759 older Catholic clergy in the Rush Religious Orders Study without baseline dementia, stroke, Parkinson's disease, or severe performance-based mobility disability (defined as gait speed less than or equal to 0.4 m/s) and at least one follow-up mobility evaluation were evaluated over a mean of 8.5 (SD = 3.8) years. All participants were queried about musculoskeletal pain in the year before baseline and underwent annual assessment of mobility. Results. Using a proportional hazards model adjusted for age, sex, and education, the hazard for incident severe mobility disability was greater for participants reporting pain in the year before baseline (odds ratio = 1.47, 95% confidence interval = 1.17–1.85). Results were unchanged after adjusting for self-reported mobility disability, gait speed, depressive symptoms, body mass index, physical activity, chronic medical conditions, and analgesic use. Compared with no report of musculoskeletal pain, musculoskeletal pain in one or two areas was associated with a 30% greater hazard for incident disability (odds ratio = 1.31, 95% confidence interval = 1.00–1.70). Musculoskeletal pain in three or more areas was associated with an 80% greater hazard for incident disability (odds ratio = 1.80, 95% confidence interval = 1.31–2.47). In participants without baseline self-reported mobility disability (n = 486), musculoskeletal pain was associated with greater hazard for incident self-reported mobility disability (odds ratio = 1.38, 95% confidence interval = 1.11–1.73). Conclusion. In older persons, musculoskeletal pain is associated with incident mobility disability. [ABSTRACT FROM PUBLISHER]
