Arthritis, physical function, and disability among older Mexican Americans over 23 years of follow-up
Our study demonstrates the independent effect of arthritis in increasing ADL and mobility disability and decreased physical function in older Mexican Americans over 23-years of follow-up
Effect of Electronic Activity Monitors and Pedometers on Health: Results from the Tame Health Pilot Randomized Pragmatic Trial
Background: Brief counseling and self-monitoring with a pedometer are common practice within primary care for physical activity promotion. It is unknown how high-tech electronic activity monitors compare to pedometers within this setting. This study aimed to investigate the outcomes, through effect size estimation, of an electronic activity monitor-based intervention to increase physical activity and decrease cardiovascular disease risk. Method: …
Impact of Self-Care and Mobility on One or More Post-Acute Care Transitions
Objective: To investigate the association between functional status and post-acute care (PAC) transition(s). Methods: Secondary analysis of 2013-2014 Medicare data for individuals aged ≥66 years with stroke, lower extremity joint replacements, and hip/femur fracture discharged to one of three PAC settings (inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies). Functional scores were co-calibrated into a 0-100 …
Comparisons of the Association of Family and Social Factors With Functional Limitations Across the United States, Mexico, and South Korea: Findings From the HRS Family of Surveys
Objective: The association of family and social factors with the level of functional limitations was examined across the United States, Mexico, and Korea. Method: Participants included adults from the 2012 Health and Retirement Study ( n = 10,017), Mexican Health and Aging Study ( n = 6,367), and Korean Longitudinal Study of Aging ( n = 4,134). A common functional limitation scale was created based on Rasch analysis with a higher score indicating…
Functional Status Is Associated With 30-Day Potentially Preventable Readmissions Following Home Health Care
BACKGROUND: Beginning in 2019, home health agencies' rates of potentially preventable hospital readmissions over the 30 days following discharge will be publicly reported. OBJECTIVES: Our primary objective was to determine the association between patients' functional status at discharge from home health care and 30-day potentially preventable readmissions. A secondary objective was to identify the most common conditions resulting in potentially p…
Muscle weakness and functional limitations in an ethnically diverse sample of older adults
Objectives: Muscle weakness is often linked to functional limitations in older adults. However, certain demographic characteristics, such as ethnicity, may differentially impact the association between weakness and functional limitations. This investigation sought to (1) identify sex- and ethnically-specific muscle weakness thresholds associated with functional limitations among older adults, and (2) determine the odds of functional limitations f…
Association Between Lower Extremity Performance and Health-Related Quality of Life in Elderly Mexican Americans
Increased LEP was associated with slower rates of decline in physical and mental HRQoL in older Mexican Americans
Handbook for Clinical Research: Design, Statistics, and Implementation
Inpatient Rehabilitation Volume and Functional Outcomes in Stroke, Lower Extremity Fracture, and Lower Extremity Joint Replacement
BACKGROUND: It is unclear if volume-outcome relationships exist in inpatient rehabilitation. OBJECTIVES: Assess associations between facility volumes and 2 patient-centered outcomes in the 3 most common diagnostic groups in inpatient rehabilitation. RESEARCH DESIGN: We used hierarchical linear and generalized linear models to analyze administrative assessment data from patients receiving inpatient rehabilitation services for stroke (n=202,423), l…
Social Support, Stressors, and Frailty Among Older Mexican American Adults
Frailty has been hypothesized to reflect age-related physiological vulnerability to stressors, and the analyses presented indicate partial support for this hypothesis in an older sample of Mexican Americans. Future research needs to incorporate measures of stressors and social support in examining those who become frail, especially in minority populations
Frailty as a Predictor of Falls in Older Mexican Americans
Frailty increases the odds of falls in older Mexican Americans. Interventions tailored to reduce fall incidence and improve health care quality for older Mexican Americans are needed
The Protective Effect of Neighborhood Composition on Increasing Frailty Among Older Mexican Americans: A Barrio Advantage
Personal as well as neighborhood characteristics confer protective effects on individual health in this representative, well-characterized sample of older Mexican Americans. Potential mechanisms that may be implicated in the protective effect of ethnically homogenous communities are discussed
Mexican Americans and Frailty: Findings From the Hispanic Established Populations Epidemiologic Studies of the Elderly
Objectives. We examined the prevalence of frailty among Mexican American older adults and explored the correlates associated with becoming frail to determine their affect on disability and morbidity in this population. Methods. We studied the trajectory of frailty over 10 years in 2049 Mexican Americans participating in the Hispanic Established Populations Epidemiologic Studies of the Elderly. We constructed a frailty index based on weight loss, …
Associations Between Positive Emotion and Recovery of Functional Status Following Stroke
OBJECTIVE: Accumulating evidence indicates the beneficial effects of positive emotion on health and general well-being in older age. Less evidence is available on whether positive emotion supports improvement in functional status after an acute medical event such as stroke. This study examined the association between positive emotion at discharge from inpatient medical rehabilitation and functional status 3 months later in persons with stroke. ME…
The Effect of Depressive Symptoms on the Association between Functional Status and Social Participation
Hypertension in Older Adults and the Role of Positive Emotions
OBJECTIVE: Negative emotions have been linked to increases in blood pressure, but relations between positive emotion and blood pressure have not been investigated. Our aim was to test the hypothesis that high positive emotion would be associated with lower blood pressure in older adults. METHODS: A cross-sectional study included 2564 Mexican Americans aged 65 or older living in one of five southwestern states. Primary measures included blood pres…
Does Change in Functional Performance Affect Quality of Life in Persons with Orthopaedic Impairment
Outcomes and Reimbursement of Inpatient Rehabilitation Facilities and Subacute Rehabilitation Programs for Medicare Beneficiaries With Hip Fracture
OBJECTIVE: We sought to assess whether outcomes and reimbursement differ for Medicare beneficiaries with hip fracture when treated in an inpatient rehabilitation facility (IRF) compared with a skilled nursing facility (SNF) subacute rehabilitation program. PARTICIPANTS: Clinical data were linked with Medicare claims for 29,793 Medicare fee-for-service beneficiaries with a recent hip fracture who completed treatment in 1996 or 1997 in rehabilitati…
Disparity in Health Services and Outcomes for Persons With Hip Fracture and Lower Extremity Joint Replacement
OBJECTIVE: Examine disparity in health services and outcomes for adults with a hip fracture or lower extremity joint replacement. MATERIALS AND METHODS: This study examined 28,522 patient records including 12,328 (mean age 76.6 years) with hip fracture and 16,194 (mean age 71.8 years) with joint replacement. RESULTS: Non-Hispanic white and black patients were significantly (P < 0.05) more likely to be discharged home alone and responsible for the…
