Luiz MM, Máximo RDO, de Oliveira DC, Ramírez PC, de Souza AF, Delinocente MLB, Cochar-Soares N, Steptoe A, de Oliveira C, Alexandre TDS. Could poor glycaemic control be a predictor of walking speed decline in older adults? Evidence from the English Longitudinal Study of Ageing. Diabetes Obes Metab 2024; 26:2349-2358. [PMID: 38514386 PMCID: PMC11078602 DOI: 10.1111/dom.15549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/13/2024] [Accepted: 02/22/2024] [Indexed: 03/23/2024]
Abstract
AIM Although diabetes is a risk factor for walking speed decline in older adults, it remains unclear how glycaemic control [assessed by glycated haemoglobin (HbA1c)] might affect the long-term trajectories of walking speed. We investigated whether the glycaemic control status accelerates the walking speed decline and whether this decline differs depending on previous mobility conditions. MATERIALS AND METHODS In total, 3202 individuals aged ≥60 years from the English Longitudinal Study of Ageing (ELSA) were classified at baseline and after 4 and 8 years of follow-up according to glycaemic control status as 'without diabetes' (no self-reported diabetes and HbA1c <6.5%), 'good glycaemic control' (self-reported diabetes and HbA1c ≥6.5% and <7.0%) and 'poor glycaemic control' (PGC) (self-reported diabetes and HbA1c ≥7.0%). The generalized linear mixed models verified the walking speed trajectories in m/s. A second analysis was performed, including only participants without slowness at baseline (>0.8 m/s). RESULTS Compared with the status 'without diabetes', the annual walking speed decline was -0.015 m/s for PGC and -0.011 m/s for good glycaemic control, totalling -0.160 and -0.130 m/s, respectively, over 8 years. Among those without slowness at baseline, only PGC had a significant walking speed decline, corresponding to -0.014 m/s per year and -0.222 m/s over 8 years. CONCLUSIONS Poor glycaemic control is a discriminator of walking speed decline in older adults, regardless of previous mobility conditions. It may serve as an early screening tool for those at risk of decreased functional performance later in life.

Abstract
We tested if a dance trial yielded improvements in physical function and cardiorespiratory fitness (CRF) in middle-aged/older Latino adults. Physical activity was assessed using the Community Healthy Activities Model Program for Seniors, physical function with the Short Physical Performance Battery (SPPB) protocol, and estimated CRF with the Jurca nonexercise test model. Multivariate analysis of covariance models found significant change in SPPB protocol total scores, F(1, 329) = 4.23, p = .041, and CRF, F(1, 329) = 5.16, p = .024, between the two study arms in favor of the dance group. Mediation models found moderate- to vigorous-intensity physical activity to mediate to mediate between group and SPPB scores (β = 0.054, 95% confidence interval [0.0142, 0.1247]). Moderate- to vigorous-intensity physical activity and total physical activity were found to partially mediate between group and CRF (β = 0.02, 95% confidence interval [-0.0261, 0.0751]), with the direct pathway no longer being significant (p > .05). This provides support for Latin dance programs to have an effect on SPPB protocol and CRF.

Abstract
Skeletal muscle index (SMI) remains a strong predictor of mortality in cirrhosis patients. However, the extent to which SMI varies by race/ethnicity has not been fully evaluated. Among 317 patients, 55% identified themselves as non-Hispanic White (NHW), 26% Hispanic White (HW), 13% Asian, and 6% Black. There was significant variation in SMI by race/ethnicity; median SMI was lowest in Asian and highest in Black patients. There were significant differences of sarcopenia by race/ethnicity using established SMI cutpoints: 48% NHW, 33% HW, 67% Asian, and 37% Black (P = 0.003). Using these cutpoints, SMI was significantly associated with waitlist mortality only in NHW patients but not in other racial/ethnic groups.

Abstract
BACKGROUND Emerging research has elucidated pathophysiological relationships among diabetes, disability, cognitive impairment, and incident dementia. However, the relationships between diabetes, disability, and dementia have been largely underexamined in Latino populations, which have a disproportionate prevalence of diabetes and its complications. AIMS This study examines diabetes as a risk factor for subsequent disability and dementia risk in a Mexican-origin older adult sample. METHODS The data are drawn from eight waves (1993-2013) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE; N = 3,050, mean age at baseline = 73.6 (±6.8)). Respondents' diabetes status at baseline was ascertained by self-report. Disability was assessed using eight functional domains assessed through the Lawton Instrumental Activities of Daily Living (IADL) Scale. Dementia risk was assessed using a Mini-Mental Status Exam (MMSE) score below 18 and the need for aid with at least two IADLs. We used multivariable Cox proportional hazards models to predict the relation between diabetes and time to disability, cognitive impairment, and incident dementia, adjusting for age at migration, socioeconomic status, acculturation, and health status. RESULTS At baseline, diabetes prevalence was 28.1%, and 37.7% had IADL disability. Diabetes was associated with a higher risk of developing dementia (Hazard Ratio (HR) = 1.22, p < .001) over the approximetely 20 year study period. In addition, immigrants who migrated at age 50 or older had a higher dementia risk (HR = 1.35, p = .01) when compared to their US-born counterpart. CONCLUSION Our results highlight the importance of better characterizing the role of diabetes and nativity in the co-occurrence of disability and dementia risk.

Abstract
BACKGROUND Latinos are the fastest growing minority group of the older adult population. Although physical activity (PA) has documented health benefits, older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance, popular among Latinos, holds promise as a culturally relevant form of PA. PURPOSE To describe self-reported and device-assessed changes in PA as a result of a randomized controlled trial of BAILAMOS, a 4-month Latin dance program with a 4-month maintenance program, versus a health education control group. METHODS Adults, aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels at baseline, and risk for disability were randomized to the dance program (n = 167) or health education condition (n = 166). Data were analyzed using multilevel modeling with full information maximum likelihood. RESULTS A series of multilevel models revealed significant time × group interaction effects for moderate-to-vigorous physical activity (MVPA), dance PA, leisure PA, and total PA. Exploring the interaction revealed the dance group to significantly increase their MVPA, dance PA, leisure PA, and total PA at months 4 and 8. Household PA and activity counts from accelerometry data did not demonstrate significant interaction effects. CONCLUSIONS The study supports organized Latin dance programs to be efficacious in promoting self-reported PA among older Latinos. Efforts are needed to make dancing programs available and accessible, and to find ways for older Latinos to add more PA to their daily lives. CLINICAL TRIAL INFORMATION NCT01988233.

Abstract
BACKGROUND Depressive symptoms are common in older adults and predict functional dependency. AIMS To examine the ability of depressive symptoms to predict low physical performance over 20 years of follow-up among older Mexican Americans who scored moderate to high in the Short Physical Performance Battery (SPPB) test and were non-disabled at baseline. METHODS Data were from the Hispanic Established Population for the Epidemiologic Study of the Elderly. Our sample included 1545 community-dwelling Mexican American men and women aged 65 and older. Measures included socio-demographics, depressive symptoms, SPPB, handgrip strength, activities of daily living, body mass index (BMI), mini-mental state examination, and self-reports of various medical conditions. General Equation Estimation was used to estimate the odds ratio of developing low physical performance over time as a function of depressive symptoms. RESULTS The mean SPPB score at baseline was 8.6 ± 1.4 for those with depressive symptoms and 9.1 ± 1.4 for those without depressive symptoms. The odds ratio of developing low physical performance over time was 1.53 (95% Confidence Interval = 1.27-1.84) for those with depressive symptoms compared with those without depressive symptoms, after controlling for all covariates. CONCLUSION Depressive symptoms were a predictor of low physical performance in older Mexican Americans over a 20-year follow-up period. Interventions aimed at preventing decline in physical performance in older adults should address management of their depressive symptoms.

Abstract
The objective of this study was to examine pain as a predictor of frailty over 18 years of follow-up among older Mexican Americans who were nonfrail at baseline. Data were from a prospective cohort study of 1545 community-dwelling Mexican Americans aged ≥67 years from the Hispanic Established Populations for the Epidemiological Study of the Elderly (1995/1996-2012/2013). Frailty was defined as meeting 2 or more of the following: unintentional weight loss of >10 pounds, weakness, self-reported exhaustion, and slowness. The independent predictor was self-reported pain. Covariates included age, sex, marital status, education, comorbid conditions, body mass index, Mini-Mental State Examination, depressive symptoms, and limitation in activities of daily livings. General equation estimation was performed to estimate the odds ratio of frailty as a function of pain. A total of 538 participants (34.8%) reported pain at baseline. The prevalence of frailty among those with pain ranged from 24.4% in wave 3 to 41% in wave 8. The odds ratio of becoming frail over time as a function of pain was 1.71; 95% confidence interval: 1.41 to 2.09 after controlling for all covariates. Older age, hip fracture, high depressive symptoms, and activities of daily living disability were also associated with higher odds of becoming frail over time. Female participants and those with higher levels of education and high Mini-Mental State Examination scores were less at risk. In conclusion, pain was a significantly predictor of frailty. Early assessment and better management of pain may prevent early onset of frailty in older Mexican Americans.

Abstract
Background: Diabetes-related disability occurs in approximately two-thirds of older adults with diabetes and is associated with loss of independence, increased health care resource utilization, and sedentary lifestyle. The objective of this randomized controlled trial was to determine the effect of a center-based functional circuit exercise training intervention followed by a 10-week customized home-based program in improving mobility function in sedentary older adults with diabetes. Methods: Participants (n = 111; mean age 70.5 [7.1] y; mean body mass index 32.7 [5.9] kg/m2) were randomized to either a moderate-intensity functional circuit training (FCT) plus 10-week home program to optimize physical activity (FCT-PA) primary intervention or one of 2 comparison groups (FCT plus health education [FCT-HE] or flexibility and toning plus health education [FT-HE]). Results: Compared with FT-HE, FCT-PA improvements in comfortable gait speed of 0.1 m/s (P < .05) and 6-minute walk of 80 ft were consistent with estimates of clinically meaningful change. At 20 weeks, controlling for 10-week outcomes, improvements were found between groups for comfortable gait speed (FCT-PA vs FT-HE and FCT-HE vs FT-HE) and 6-minute walk (FCT-PA vs FCT-HE). Conclusions: Functional exercise training can improve mobility in overweight/obese older adults with diabetes and related comorbidities. Future studies should evaluate intervention sustainability and adaptations for those with more severe mobility impairments.

Abstract
This article presents a systematic review of the literature on correlates/predictors of mobility limitation among community-dwelling U.S. Hispanic older adults. A search of scientific databases (PubMed, CINAHL, and PsycINFO) was conducted. After abstract and full text review, 20 epidemiologic studies that met all eligibility criteria were included. The theoretical framework of mobility was used to categorize factors related to mobility limitation. The majority of the studies reviewed (n = 17) examined some aspect of physical factors in relation to mobility limitation. Several factors emerged as important influences on mobility outcomes: diabetes mellitus, stroke, obesity, arthritis, and depression. None examined the influence of built environment. This review suggests that multilevel factors can impact both mobility limitations and disability among U.S. Hispanic older adults. However, the study findings were inconsistent, with some studies showing significant relationships or effects and others demonstrating no associations or mixed findings.

Abstract
INTRODUCTION Limited information is available on the health burden of diabetes at the state level. This study estimated state-specific attributable fractions and the number of cases attributable to diabetes for diabetes-related complications. METHODS For each state, diabetes-attributable fractions for nine diabetes complications were estimated: three self-reported complications from the 2013 Behavioral Risk Factor Surveillance System, hospitalizations with three complications from 2011 to 2014 State Inpatient Databases, and three complications from 2013 Medicare data. Attributable fractions were calculated using RR and diabetes prevalence and the total number of cases using attributable fractions and total number of complications. Adjusted RR of each complication for people with and without diabetes by age and sex was estimated using a generalized linear model. Analyses were conducted in 2015-2016. RESULTS Median state-level diabetes-attributable fractions for self-reported complications were 0.14 (range, 0.10-0.19) for mobility limitations; 0.13 (range, 0.04-0.21) for limitations in instrumental activities of daily living; and 0.12 (range, 0.06-0.20) for severe visual impairment or blindness. Median state-level diabetes-attributable fractions for diabetes-associated hospitalizations were 0.19 (range, 0.08-0.24) for congestive heart failure; 0.08 (range, 0.02-0.16) for myocardial infarction; and 0.62 (range, 0.46-0.73) for lower extremity amputations. Median state-level diabetes-attributable fractions for complications among Medicare beneficiaries were 0.17 (range, 0.14-0.23) for coronary heart disease; 0.28 (range, 0.24-0.33) for chronic kidney disease; and 0.22 (range, 0.08-0.32) for peripheral vascular disease. CONCLUSIONS Diabetes carries a significant health burden, and results vary across states. Efforts to prevent or delay diabetes or to improve diabetes management could reduce the health burden because of diabetes.

Abstract
AIMS To assess whether disturbances in glucose regulation are associated with impairment in physical performance during a 10-year follow-up. METHODS 475 Men and 603 women from the Helsinki Birth Cohort Study were studied. Glucose regulation was evaluated with a 2-h 75-g oral glucose tolerance test (OGTT) in 2001-2004. Subjects were categorised as having either impaired fasting glucose (IFG), impaired glucose tolerance (IGT), newly diagnosed diabetes or previously known diabetes. Physical performance was assessed approximately 10 years later using the validated senior fitness test (SFT). The relationship between glucose regulation and the overall SFT score was estimated using multiple linear regression models. RESULTS The mean age was 70.8 years for men and 71.0 years for women when physical performance was assessed. The mean SFT score for the whole population was 45.0 (SD 17.5) points. The SFT score decreased gradually with increased impairment in glucose regulation. Individuals with previously known diabetes had the lowest overall SFT score in the fully adjusted model (mean difference compared to normoglycaemic individuals - 11.56 points, 95% CI - 16.15 to - 6.98, p < 0.001). Both individuals with newly diagnosed diabetes and individuals with IGT had significantly poorer physical performance compared to those with normoglycaemia. No significant difference in physical performance was found between those with IFG and those with normoglycaemia. CONCLUSIONS Among older people, impaired glucose regulation is strongly related with poor physical performance. More severe disturbances in glucose regulation are associated with a greater decrease in physical function, indicating the importance of diagnosing these disturbances at an early stage.

Abstract
The relationship between blood mitochondrial DNA (mtDNA) copy number and subsequent cancer risk has been investigated previously. However, such association has never been examined in Mexican Americans. In the current study, we examined association between social-demographic factors and blood mtDNA copy number, as well as longitudinal relationship between cancer and mtDNA copy number, among 10,802 Mexican Americans in the Mano-A-Mano Mexican American Cohort. Overall, mtDNA copy number was statistically significantly higher among participants who developed cancer during the study period than among cancer-free controls (0.17 vs 0.13, P = 0.007). Among cancer-free control participants, mtDNA copy number significantly differed by social-demographic characteristics. However, there was a large degree of heterogeneity in these effects across the mtDNA copy number distribution. In the longitudinal analysis, we observed that higher mtDNA copy number was positively associated with increased risk of all cancer types (adjusted hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.09–1.17). Participants with mtDNA copy number in the fourth (highest) quartile had a higher risk of all cancer (adjusted HR, 2.12; 95% CI, 1.65–2.73) than did participants in the first (lowest) quartile. In summary, our results in Mexican Americans support an association between increased mtDNA copy number and cancer risk. Our results also suggest that mtDNA copy number may be influenced by social and demographic factors.

Abstract
AIMS To evaluate how depression and diabetes severity impact disability progression among Mexican Americans over a 15-year period. METHODS We used seven waves of the Hispanic Established Population for the Epidemiologic Study of the Elderly (H-EPESE). Primary disability outcomes included the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales. Explanatory variables included time since diagnosis with diabetes (no type 2 diabetes, 1-10, 11-20, 21+), an indicator of disease severity, and depression. Longitudinal generalized estimating equation models were used to estimate the relationship between time since diabetes diagnosis, depressive symptoms and ADL and IADL disability progression over a 15-year time period. RESULTS Years since diabetes diagnosis was associated with more rapid ADL and IADL disability progression compared to those without type 2 diabetes. Depression accelerated the disabling process in participants who were diagnosed with diabetes 11years or more years ago. CONCLUSIONS Longer duration of diabetes and greater symptoms of depression increase vulnerability for disability among older Mexican American adults.

Abstract
Sarcopenia is an age-related syndrome characterised by progressive and generalised loss of skeletal muscle mass and strength; it is a major contributor to the risk of physical frailty, functional impairment in older people, poor health-related quality of life and premature death. Many different definitions have been used to describe sarcopenia and have resulted in varying estimates of prevalence of the condition. The most recent attempts of definitions have tried to integrate information on muscle mass, strength and physical function and provide a definition that is useful in both research and clinical settings. This review focuses on the epidemiology of the three distinct physiological components of sarcopenia, and highlights the similarities and differences between their patterns of variation with age, gender, geography and time and the individual risk factors that cluster selectively with muscle mass, strength and physical function. Methods used to measure muscle mass, strength and physical functioning and how differences in these approaches can contribute to the varying prevalence rates will also be described. The evidence for this review was gathered by undertaking a systematic search of the literature. The descriptive characteristics of muscle mass, strength and function described in this review point to the urgent need for a consensual definition of sarcopenia incorporating these parameters.

Abstract
BACKGROUND AND OBJECTIVES Hispanics are the most rapidly aging minority population in the United States. Our objective is to provide a summary of current knowledge regarding disability among Hispanics, and to propose an agenda for future research. RESEARCH DESIGN AND METHODS A literature review was conducted to identify major areas of research. A life course perspective and the Hispanic Paradox were used as frameworks for the literature review and for identifying future areas of research. RESULTS Four research areas were identified: (1) Ethnic disparities in disability; (2) Heterogeneity of the U.S. older Hispanic population; (3) Risk factors for disability; and (4) Disabled life expectancy. Older Hispanics are more likely than non-Hispanic whites to be disabled or to become disabled. Disability varied by country of origin, nativity, age of migration, and duration in the United States. Important risk factors for disability included chronic health conditions, depression, and cognitive impairment. Protective factors included positive affect and physical activity. Older Hispanics have longer life expectancy than non-Hispanic whites but spend a greater proportion of old age disabled. Future research should continue to monitor trends in disability as younger generations of Hispanics reach old age. Attention needs to be given to regional variation within the United States for disability prevalence, early-life risk factors, and factors that may contribute to variation in disabled life expectancy. There is also an urgent need for interventions that can effectively prevent or delay the onset of disability in older Hispanics. DISCUSSION AND IMPLICATIONS Considerable research has examined disability among older Hispanics, but continued research is needed. It is important that research findings be used to inform public policies that can address the burden of disability for older Hispanic populations.

Abstract
In the current study, we examined cross-sectional associations among social-demographics, lifestyle behaviors, and relative telomere length (RTL) in peripheral blood leukocytes, as well as longitudinal relationships among major chronic diseases, weight gain, and RTL, among 12,792 Mexican Americans aged 20 to 85 years in the Mano-A-Mano, the Mexican American Cohort. As expected, RTL was inversely correlated with age (ρ=-0.15, ρ<0.001). In the multivariate analysis, we found that RTL was positively correlated with levels of education (ρ=0.021), self-insurance (ρ=0.041), body mass index (BMI) (ρ<0.001), and sleeping time per day (ρ for trend<0.001), and RTL was inversely correlated with sitting time per day (ρ for trend =0.001). In longitudinal analysis, we found that longer RTL was modestly but positively associated with increased risks of overall cancer (adjusted hazard ratio (adj.HR)=1.05, 95% conference interval (95%CI)=1.02-1.09). In quartile analysis, 4th quartile (longest RTL) was associated with 1.53-fold increased risk of overall cancer (adj.HR=1.53, 95%CI=1.11-2.10), compared to 1st quartile (shortest RTL). RTL was reversely associated with the risk of type-2 diabetes (adj.HR=0.89, 95%CI=0.82-0.94). In quartile analysis, 4th quartile (longest RTL) was associated with 48% decreased risk of typle-2 diabetes (adj.HR=0.52, 95%CI=0.32-0.70), compared to 1st quartile (shortest RTL). In addition, longer RTL was a positive predictor of at least 10% weight gain (adj.HR=1.03, 95%CI=1.00-1.05). In summary, our results in Mexican Americans support the notion that telomere length is a biological mechanism by which social demographics and health behaviors “get under the skin” to affect health.

Abstract
BACKGROUND The identification of novel rehabilitative impairments that are risk factors for mobility limitations may improve their prevention and treatment among older adults. We tested the hypothesis that impaired rhythmic interlimb ankle and shoulder coordination are risk factors for subsequent mobility limitations among older adults. METHODS We conducted a 1-year prospective cohort study of community-dwelling older adults (N = 99) aged 67 years and older who did not have mobility limitations (Short Physical Performance Battery score > 9) at baseline. Participants performed antiphase coordination of the right and left ankles or shoulders while paced by an auditory metronome. Using multivariable logistic regression, we determined odds ratios (ORs) for mobility limitations at 1-year follow-up as a function of coordination variability and asymmetry. RESULTS After adjusting for age, sex, body mass index, Mini-Mental State Examination score, number of chronic conditions, and baseline Short Physical Performance Battery score, ORs were significant for developing mobility limitations based on a 1 SD difference in the variability of ankle (OR = 1.88; 95% confidence interval [CI]: 1.16-3.05) and shoulder (OR = 1.96; 95% CI: 1.17-3.29) coordination. ORs were significant for asymmetry of shoulder (OR = 2.11; 95% CI: 1.25-3.57), but not ankle (OR = 0.95; 95% CI: 0.59-1.55) coordination. Similar results were found in unadjusted analyses. CONCLUSIONS The results support our hypothesis that impaired interlimb ankle and shoulder coordination are risk factors for the development of mobility limitations. Future work is needed to further examine the peripheral and central mechanisms underlying this relationship and to test whether enhancing coordination alters mobility limitations.

Abstract
OBJECTIVE The aim of this study is to determine the independent and joint effects of muscle weakness and diabetes on incident activities of daily living (ADL) disability in older Mexican Americans. METHOD A subsample of 2,270 Mexican Americans aged at least 65 years at baseline were followed for 19 years. Handgrip strength was normalized to body weight (normalized grip strength [NGS]). Weakness was defined as NGS ≤0.46 in males and ≤0.30 in females. Diabetes and ADL disability were self-reported. RESULTS Compared with participants that were not weak and did not have diabetes, those that had diabetes only, were weak only, and were both weak and had diabetes experienced a 1.94 (95% confidence interval [CI] = [1.89, 1.98]), 1.17 (CI = [1.16, 1.19]), and 2.12 (CI = [2.08, 2.16]) higher rate for ADL disability, respectively. DISCUSSION Muscle weakness and diabetes were independently and jointly associated with higher rates for ADL disability in older Mexican Americans.

Abstract
Musculoskeletal ageing is a major public health concern owing to demographic shifts in the population. Sarcopenia, generally defined as the age-related loss of muscle mass and function, is associated with considerable risk of falls, loss of independence in older adults and hospitalization with poorer health outcomes. This condition is therefore associated with increased morbidity and health care costs. As with bone mass, muscle mass and strength increase during late adolescence and early adulthood, but begin to decline substantially from ∼50 years of age. Sarcopenia is characterized by many features, which include loss of muscle mass, altered muscle composition, infiltration with fat and fibrous tissue and alterations in innervation. A better understanding of these factors might help us to develop strategies that target these effects. To date, however, methodological challenges and controversies regarding how best to define the condition, in addition to uncertainty about what outcome measures to consider, have delayed research into possible therapeutic options. Most pharmacological agents investigated to date are hormonal, although new developments have seen the emergence of agents that target myostatin signalling to increase muscle mass. In this review we consider the current approaching for defining sarcopenia and discuss its epidemiology, pathogenesis, and potential therapeutic opportunities.

Abstract
Type 2 diabetes, a common metabolic disease in older people, is a major risk factor for functional limitation, impaired mobility, and loss of independence. In older people, the pathogenesis of functional limitation and disability is complex and multifactorial. A number of potential pathways are involved including cardiovascular disease, peripheral neuropathy, overweight, osteoarthritis, visual deficit, and cognitive impairment, conditions that are all more prevalent among patients with diabetes. Sarcopenia, a geriatric condition characterized by a progressive and generalized loss of skeletal muscle mass and strength, is also involved in the pathogenesis of functional limitations and disability. Recent research has shown that older patients with type 2 diabetes are often affected by skeletal muscle impairment, leading to reduced muscle strength and physical function. Insulin resistance, hyperglycemia, muscle fat infiltration, and peripheral neuropathies are hypothesized as the fundamental biological mechanisms leading to muscle impairment in people with diabetes. This review summarizes the current literature on the biological pathways responsible for skeletal muscle dysfunction in type 2 diabetes and analyzes the role of decline in muscle strength and quality on the association between diabetes and mobility disability.

Abstract
Objective: The authors examined the contribution of life-course exposures to gender differences in mobility in later life. Method: Data originate from a survey of persons aged 60 and older living in six Latin American and Caribbean cities ( n = 10,661). Lower extremity limitations (LEL) were defined as the presence of three or more reported difficulties with five activities: lifting and carrying 10 lb, walking several blocks, climbing a flight of stairs, kneeling/ stooping/crouching, and getting up from a chair. Data were pooled after testing homogeneity of effects across cities. A multivariate model was fitted using logistic regression analysis. Complete data analyses were performed on 8,166 (72%) participants. Results: Prevalence of LEL varies across cities (9.3—23.7% in men, 23.3—42.9% in women). Intervening life-course and health factors explained a small proportion of the gender difference in LEL (odds ratio = 2.39; 95% confidence interval = 2.04—2.79). Childhood hunger was predictive of LEL in women, and a stronger association between depression and LEL was found in men than in women. Little education and insufficient income were associated with LEL for both men and women. Discussion: Life-course exposures predict mobility, but further research is needed to identify intervening factors relating gender to mobility in old age.

Abstract
Background The extant literature on gender differentials in health in developed countries suggests that women outlive men at all ages, but women report poorer health than men. It is well established that Indian women live longer than men, but few studies have been conducted to understand the gender dimension in self-rated health and self-reported disability. The present study investigates gender differentials in self-rated health (SRH) and self-reported disability (SRD) among adults in India, using a nationally representative data. Methods Using data on 10,736 respondents aged 18 and older in the 2007 WHO Study on Global Ageing and Adult Health in India, prevalence estimates of SRH are calculated separately for men and women by socio-economic and demographic characteristics. The association of SRH with gender is tested using a multinomial logistic regression method. SRD is assessed using 20 activities of daily living (ADL). Further, gender differences in total life expectancy (TLE), disability life expectancy (DLE) and the proportion of life spent with a disability at various adult ages are measured. Results The relative risk of reporting poor health by women was significantly higher than men (relative risk ratio: 1.660; 95% confidence Interval (CI): 1.430–1.927) after adjusting for socio-economic and demographic characteristics. Women reported higher prevalence of severe and extreme disability than men in 14 measures out of a total20 ADL measures. Women aged less than 60 years reported two times more than men in SRD ≥ 5 ADLs. Finally, both DLE and proportion of life spent with a disability were substantially higher for women irrespective of their ages. Conclusion Indian women live longer but report poorer health than men. A substantial gender differential is found in self-reported disability. This makes for an urgent call to health researchers and policy makers for gender-sensitive programs.

Abstract
This study examined possible subtle degradation in sensory functions, balance, and mobility in older adults with type 2 diabetes (T2D) prior to overt development of diabetic peripheral neuropathy (DPN). Twenty-five healthy controls (HC group, age = 74.6 ± 5.4) and 35 T2D elderly without DPN (T2D group, age = 70.6 ± 4.7) were recruited. Sensory assessment included vibrotactile sensitivity, bilateral caloric weakness, and visual contrast sensitivity. Self-report measures comprised of Activity-Specific Balance Confidence (ABC), Human Activity Profile–adjusted activity scores (HAP-AAS), falls, and mobility disability. Performance measures included modified Timed-Up and Go (mTUG), Clinical Test of Sensory Integration for Balance (mCTSIB), and Frailty and Injuries (FICSIT-4) balance test. T2D group demonstrated significantly worse bilateral caloric weakness, marginally higher threshold of vibrotactile sensitivity and lower visual contrast sensitivity, and as well as signifcantly lower HAP-AAS. A significantly higher proportion of the T2D group failed mCTSIB Condition 4 than in the HC group. Subtle changes in multiple sensory systems of older adults with T2D may reduce redundancy available for balance control while performing challenging activities much before DPN development.

Abstract
Background The rapid population ageing has been accompanied by a growing number of older adults experiencing chronic conditions, especially diabetes and hypertension, which are conditions associated to the decline in physical functioning. The aim of this study was to investigate changes in the strength of the association between mobility and two chronic conditions (hypertension and diabetes) in a large representative sample of Brazilian older adults over a ten year period. Methods The data came from the Brazilian National Household Sample Survey (PNAD) of 1998, 2003 and 2008. The sample comprised 28,943 participants aged 60 years and older investigated in 1998, 35,042 in 2003 and 41,269 in 2008, totalling 105,254 older adults. The dependent variable was the physical mobility index (PMI) constructed based on the Item Response Theory (IRT) using five physical mobility indicators. The chronic conditions were self-reported and the confounders included: age, sex, schooling, ethnicity, family income, household composition, other co-morbidities and use of health services. The association between physical mobility (three different groups) and chronic conditions (hypertension and diabetes) was performed using multinomial logistic regression. Results Over the ten year period the prevalence of hypertension increased from 44 % (1998), 49 % (2003) to 53 % (2008) (p < 0.001). Similar pattern was observed for the prevalence of diabetes: 10 % in 1998, 13 % in 2003 and 16 % in 2008 (p < 0.001). Overall, physical mobility showed a statistical significant association with both chronic diseases studied even after adjusting for potential confounders. The time-disease interaction term was significant (p < 0.05) for the two chronic conditions studied, and the strength of the associations decreased over the first five years, but it was not sustained between 2003 and 2008. Conclusions Despite the increases observed in the prevalence of the hypertension and diabetes over the ten year period, the decrease in strength of the association with physical mobility during the first period could be explained by improvements in health services and treatment of older adults. Special attention should be given to the treatment and management of diabetes in order to avoid declines in physical mobility levels.

Abstract
Serious mental illness (SMI) and Latino ethnicity can produce a compounded health disparity, placing individuals at particularly high risk for excess morbidity and premature mortality. Culturally sensitive strategies are needed to improve health behaviors, including exercise and healthy eating within this population. The purpose of this qualitative study was to explore facilitators, barriers, and preferences for health behavior change among Latinos with SMI. Semi-structured interviews were conducted with 20 Latinos with SMI who were enrolled in a randomized trial evaluating the effectiveness of a motivational health promotion intervention, In SHAPE. The interviews explored perceived facilitators and barriers to health behavior change, focusing on the role of family, and exercise preferences. The primary facilitator identified by participants was having someone (either professional or significant other) to hold them accountable for engaging in healthy behaviors. A major barrier to making lasting health behavior change was cultural influences on food. Participants preferred aerobic exercises set to music that kept their minds occupied in contrast to strenuous activities such as weight lifting. This exploratory research provides insight into the perspectives, experiences, and preferences of Latinos with SMI participating in a health promotion intervention. Findings will be used to inform future health promotion efforts adapted to meet the needs of an ethnically diverse, underserved community.

Abstract
BACKGROUND Physical activity (PA) has documented health benefits, but older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance holds a promise as a culturally appropriate form of PA that challenges individuals physically and cognitively. This paper describes a randomized controlled trial that will test the efficacy of BAILAMOS, a 4-month Latin dance program followed by a 4-month maintenance program, for improving lifestyle PA and health outcomes. METHODS Older adults (n=332), aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels, and at risk for disability will be randomized to one of two programs, a dance program or health education control group. BAILAMOS is a 4-month program that meets two times per week for one 1h per session. Dance sessions focus on instruction, including four styles of dance, and couples dancing. Bi-monthly Fiestas de Baile (dance parties) are also included, in which participants dance and practice what they have learned. Monthly 1-hour discussion sessions utilize a Social Cognitive framework and focus on knowledge, social support, and self-efficacy to increase lifestyle PA. The health education control group will meet one time per week for two 2h per session. OUTCOMES Primary outcomes including PA changes and secondary outcomes including self-efficacy, physical function, cognitive function, and disability will be assessed at baseline, 4, and 8 months. It is hypothesized that PA, self-efficacy, physical function, cognitive function, and functional limitations and disability scores will be significantly better in the BAILAMOS group at 4 and 8 months compared to the control group.

Physical Activity, Physical Performance, and Biological Markers of Health among Sedentary Older Latinos. Curr Gerontol Geriatr Res 2014; 2014:535071. [PMID: 25136359 PMCID: PMC4119654 DOI: 10.1155/2014/535071] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2014] [Accepted: 05/26/2014] [Indexed: 11/18/2022] Open
Abstract
Background. Physical activity is associated with better physical health, possibly by changing biological markers of health such as waist circumference and inflammation, but these relationships are unclear and even less understood among older Latinos-a group with high rates of sedentary lifestyle. Methods. Participants were 120 sedentary older Latino adults from senior centers. Community-partnered research methods were used to recruit participants. Inflammatory (C-reactive protein) and metabolic markers of health (waist circumference, HDL-cholesterol, triglycerides, insulin, and glucose), physical activity (Yale physical activity survey), and physical performance (short physical performance NIA battery) were measured at baseline and 6-month followup. Results. Eighty percent of the sample was female. In final adjusted cross-sectional models, better physical activity indices were associated with faster gait speed (P < 0.05). In adjusted longitudinal analyses, change in self-reported physical activity level correlated inversely with change in CRP (β = -0.05; P = 0.03) and change in waist circumference (β = -0.16; P = 0.02). Biological markers of health did not mediate the relationship between physical activity and physical performance. Conclusion. In this community-partnered study, higher physical activity was associated with better physical performance in cross-sectional analyses. In longitudinal analysis, increased physical activity was associated with improvements in some metabolic and inflammatory markers of health.

Abstract
Background To assess the association of diabetes with postoperative limitation of activities of daily living (ADLs) after primary total knee arthroplasty (TKA). Methodology/Principal Findings We used the prospectively collected data from the Mayo Clinic Total Joint Registry to assess the association of diabetes and diabetes with complications with moderate-severe ADL limitation 2- and 5-years after primary TKA. Multivariable logistic regression with general estimating equations adjusted for preoperative ADL limitation, comorbidity and demographic and clinical covariates. Odds ratio (OR) and 95% confidence interval (CI) are presented. 7,139 primary TKAs at 2-years and 4,234 at 5-years constituted the cohorts. In multivariable-adjusted analyses, diabetes was associated with higher odds of moderate-severe limitation at 2- and 5-years, 1.71 (95% CI: 1.26, 2.32; P = 0.001) and 1.66 (95% CI: 1.13, 2.46; P = 0.01). Respective ORs for patients with diabetes with complications were 2.73 (95% CI: 1.47, 5.07; P = 0.001) and 2.73 (95% CI: 1.21, 6.15; P = 0.016). Sensitivity analyses that adjusted for anxiety and depression or anxiety, depression and ipsilateral hip involvement showed minimal attenuation of magnitude of the association. Conclusions/Significance In this large study of patients who underwent primary TKA, diabetes as well as its severity were independently associated with poorer functional outcome. Given the increasing rates of both diabetes as well as arthroplasty, more insight is needed into disease-related and treatment-related factors that underlie this higher risk of ADL limitation in patients with diabetes. Poor functional outcomes may be preventable by modifying the control of diabetes and associated comorbidity in pre- and post-arthroplasty periods.

Abstract
BACKGROUND According to previous reports, the risk of disability as a result of diabetes varies from none to double. Disability is an important measure of health and an estimate of the risk of disability as a result of diabetes is crucial in view of the global diabetes epidemic. We did a systematic review and meta-analysis to estimate this risk. METHODS We searched Ovid, Medline, Embase, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature up to Aug 8, 2012. We included studies of adults that compared the risk of disability-as measured by activities of daily living (ADL), instrumental activities of daily living (IADL), or mobility-in people with and without any type of diabetes. We excluded studies of subpopulations with specific illnesses or of people in nursing homes. From the studies, we recorded population characteristics, how diabetes was diagnosed (by doctor or self-reported), domain and definition of disability, and risk estimates for disability. We calculated pooled estimates by disability type and type of risk estimate (odds ratio [OR] or risk ratio [RR]). RESULTS Our systematic review returned 3224 results, from which 26 studies were included in our meta-analyses. Diabetes increased the risk of mobility disability (15 studies; OR 1.71, 95% CI 1.53-1.91; RR 1.51, 95% CI 1.38-1.64), of IADL disability (ten studies; OR 1.65, 95% CI 1.55-1.74), and of ADL disability (16 studies; OR 1.82, 95% CI 1.63-2.04; RR 1.82, 95% CI 1.40-2.36). INTERPRETATION Diabetes is associated with a strong increase in the risk of physical disability. Efforts to promote healthy ageing should account for this risk through prevention and management of diabetes.

Gait speed correlates in a multiracial population of community-dwelling older adults living in Brazil: a cross-sectional population-based study. BMC Public Health 2013; 13:182. [PMID: 23448191 PMCID: PMC3598989 DOI: 10.1186/1471-2458-13-182] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2012] [Accepted: 02/13/2013] [Indexed: 12/25/2022] Open
Abstract
Background Gait speed is a strong predictor of a wide range of adverse health outcomes in older adults. Mean values for gait speed in community-dwelling older adults vary substantially depending on population characteristics, suggesting that social, biological, or health factors might explain why certain groups tend to self-select their gait speed in different patterns. The vast majority of studies reported in the literature present data from North American and European populations. There are few population-based studies from other regions with a different ethnicity and/or social and health conditions. To address this, the present study identified the mean usual and fast gait speeds in a representative multiracial population of community-dwelling older adults living in a developing country, and explored their association with sociodemographic, mental and physical health characteristics. Methods This was a cross-sectional population-based study of a sample of 137 men and 248 women, aged 65 years and over. Usual gait speed and fast gait speed were measured on a 4.6 m path. Participants were classified into slow, intermediate, and faster groups by cluster analysis. Logistic regression analysis was used to estimate the independent effect of each factor on the odds of presenting with a slower usual and slower fast gait speeds. Results Participants had a mean (SD) usual gait speed of 1.11 (0.27) m/s and a mean fast gait speed of 1.39 (0.34) m/s. We did not observe an independent association between gait speed and race/ethnicity, educational level, or income. The main contributors to present a slower usual gait speed were low physical activity level, stroke, diabetes, urinary incontinence, high concern about falling, and old age. A slower fast gait speed was associated with old age, low physical activity, urinary incontinence and high concern about falling. Conclusion A multiracial population of older adults living in a developing country showed a similar mean gait speed to that observed in previously studied populations. The results suggest that low physical activity, urinary incontinence and high concern about falling should not be neglected and may help identify those who might benefit from early intervention.

Abstract
OBJECTIVE To examine the association between weight change and the incidence of disability in activities of daily living (ADL) among elderly women. METHOD In 2006, 227 women aged ≥75 years and independent in ADL were selected from SABE Study (Health, Well-being, and Aging) in Sao Paulo, Brazil. The dependent variable was the report of difficulty on ≥1 ADL in 2009. Differences in weight were calculated between baseline and second interview, and converted to percentage change in relation to initial weight. A change (gain or loss) ≥5% was considered significant. A logistic regression analysis was performed including sociodemographic and health-related variables. RESULTS After adjusting, weight gain remained associated to disability (OR = 2.42; p = .027), whereas weigh loss lost significance (OR = 1.66; p = .384). DISCUSSION Weight loss is generally considered more worrisome than weight gain in elderly. However, weight loss alone was not a risk factor for disability in our study.

Abstract
UNLABELLED BACKGROUND Diabetes and increased age are known risk factors for physical disability. With the increasing prevalence of diabetes within our aging population, the future burden of disability is expected to increase. To date, there has not been a pooled estimate of the risk for disability associated with diabetes or its precursor states, impaired glucose tolerance and impaired fasting glucose. We aim to conduct a systematic review and meta-analysis of the association between prediabetes and diabetes with disability, and quantify the risk of association. METHODS/DESIGN We will search for relevant studies in Medline via Pubmed, Embase, Cochrane library and Cumulative Index to Nursing and Allied Health Literature (CINAHL), as well as scan reference lists from relevant reviews and publications included in our review. We will review all publications that include studies on human adults (18 years and older) where information is included on diabetes status and at least one measure of disability (Activities of Daily Living (ADL), Instrumental ADL (IADL) or functional/mobility limitation), and where a risk association is available for the relationship between diabetes and/or prediabetes with disability, with reference to those without diabetes.We will further conduct a meta-analysis to pool estimates of the risk of disability associated with prediabetes and diabetes. Sensitivity analysis will be conducted to assess for publication bias and study quality.Findings from this systematic review and meta-analysis will be widely disseminated through discussions with stake-holders, publication in a peer-reviewed journal and conference presentation.

Abstract
AIM To examine how diabetes in combination with cardiovascular diseases (hypertension, heart disease and stroke) and geriatric conditions (cognitive impairment and depressive symptoms) affects the odds of disability in older adults. METHODS We analyzed data from a nationally representative sample of people aged 65 years and over (n=2727) participating in the 2005 National Health Interview Survey in Taiwan. A total of 473 participants had a history of self-reported physician diagnosed diabetes. Disability was defined as reporting limitations in one or more tasks of activities of daily living (ADL), instrumental activities of daily living (IADL) or general physical activities (GPA). The Mini-Mental State Examination was used to assess cognitive function. The Center for Epidemiologic Studies Depression Scale was used to assess depressive symptoms. RESULTS After adjustment for other factors, cardiovascular diseases and geriatric conditions independently contributed to the excess odds of disability among participants with diabetes. Participants who had diabetes combined with cardiovascular diseases and geriatric conditions had odds ratios for ADL, IADL and GPA disability of 18.02 (95% CI 5.13-63.34), 7.95 (95% CI 4.07-15.50) and 5.89 (95% CI 3.19-10.90), respectively. CONCLUSION Our results highlight the high prevalence of co-occurrence of cardiovascular diseases with geriatric conditions in people with diabetes. Furthermore, the combined presence of these diseases and conditions is strongly associated with an excess odds of disability. These findings highlight the critical importance of preventing cardiovascular disease morbidity, and improving depressed mood and cognitive function in order to reduce disability risk in older adults with diabetes.

Abstract
INTRODUCTION International recommendations of the exploration of non-insulin-dependent diabetes mellitus (NIDDM) are focused on deficiency and not incapacity. AIMS (1) To estimate the incapacity of NIDDM patients through the 6-minute walk test (6MWT) data. (2) To determine their 6-minute walk distance (6MWD) influencing factors (3) To compare data of NIDDM patient group (PG; n = 100) with those of two control groups (CG): CG1 (n = 174, healthy nonobese and nonsmoker); CG2 (n = 55, obese nondiabetic free from comorbidities). POPULATION AND METHODS The anthropometric, socioeconomic, clinical, metabolic, and 6MWT data of 100 NIDDM patients (45 females) were collected. RESULTS Total sample means ± standard deviation of age, weight, and height were 54 ± 8 years, 81 ± 14 kg, and 1.64 ± 0.09 m. (1) Measured 6MWD (566 ± 81 m) was significantly lower than the theoretical 6MWD (90% ± 12%). The profile of the PG carrying the 6MWT, was as follows: 23% had an abnormal 6MWD; at the end of the 6MWT, 21% and 12% had, respectively, a low heart rate and a high dyspnea (>5/10), and 4% had desaturation during the walk. The estimated "cardiorespiratory and muscular chain" age (68 ± 16 years) was significantly higher than the chronological age. (2) The factors that significantly influenced the 6MWD (r(2) = 0.58) are included in the following equation: 6MWD (m) = -73.94 × gender (0, male; 1, female) - 3.25 × age (years) + 7.33 × leisure activity score - 35.57 × obesity (0, no; 1, yes) + 32.86 × socioeconomic level (0, low; 1, high) - 27.67 × cigarette use (0, no; 1, yes) + 8.89 × resting oxyhemoglobin saturation - 105.48. (3) Compared to the CGs, the PG had a significantly (P < 0.05) lower 6MWD (100%+9% and 100%+8%, respectively, for the CG1 and CG2). CONCLUSION NIDDM seems to accelerate the decline of the submaximal aerobic capacity evaluated through the 6MWD.

Abstract
BACKGROUND In some older adults, higher blood pressure (BP) is associated with a lower risk of mortality. We hypothesized that higher BP would be associated with greater mortality in high-functioning elders and lower mortality in elders with lower functional status. METHODS Participants were 1,562 Latino adults aged 60-101 years in the Sacramento Area Latino Study on Aging. Functional status was measured by self-reported walking speed, and BP was measured by automatic sphygmomanometer. Death information was determined from vital statistics records. RESULTS There were 442 deaths from 1998 to 2010; 53% were cardiovascular. Mean BP levels (mmHg) varied across fast, medium, and slow walkers: 136, 139, and 140 mmHg (systolic), p = .02 and 75, 76, and 77 mmHg (diastolic), p = .08, respectively. The relationship between systolic BP and mortality varied by self-reported walking speed: The adjusted hazard ratio for mortality in slow walkers was 0.96 per 10 mmHg higher systolic BP (95% confidence interval: 0.89, 1.02) and 1.29 (95% confidence interval: 1.08, 1.55) in fast walkers (p value for interaction <.001). We found a similar pattern for diastolic BP, although the interaction did not reach statistical significance; the adjusted hazard ratio per 10 mmHg higher diastolic BP was 0.89 (95% confidence interval: 0.78, 1.02) in slow walkers and 1.20 (95% confidence interval: 0.82, 1.76) in fast walkers (p value for interaction = .06). CONCLUSIONS In high-functioning older adults, elevated systolic BP is a risk factor for all-cause mortality. If confirmed in other studies, the assessment of functional status may help to identify persons who are most at-risk for adverse outcomes related to high BP.

Abstract
AIMS To describe the prevalence of limitations in Activities of Daily Living (ADL) among older Singaporeans, examine the association of ADL limitations with various self-reported health conditions, assess perceived causes of ADL limitations, and compare prevalence of health conditions among those who perceive only 'old age' vs those who perceive at least one specific health condition as the cause of their limitations. METHODS Data from a national survey of Singaporeans 60 years and over was used. The association between ADL limitations and health conditions was assessed through logistic regression. Those with ADL limitations were asked about the perceived cause/s of their limitation/ s. Any significant difference in the prevalence of health conditions between those attributing their ADL limitations only to old age and those attributing to at least one specific health condition was ascertained. RESULTS Overall prevalence of ADL limitations was 9.7%. Joint/nerve pain, stroke, pelvic/femoral fractures, heart diseases, diabetes, osteoporosis, chronic respiratory illness and renal/urinary tract illness were significantly associated with ADL limitations, and the most common perceived cause was 'old age' (33%). The prevalence of most health conditions was similar in older adults attributing their limitations to only 'old age' and to at least one specific health condition. CONCLUSION Clinical suspicion is called for if individuals with ADL limitations attribute them solely to 'old age'.

BMC Public Health 2011; 11:953.

Abstract
BACKGROUND Diabetes is associated with an increased risk of functional decline in older adults. Few studies have investigated the contribution of functional decline to excess mortality risk in older people with diabetes. The aim of this study was to examine how diabetes in combination with different levels of functional decline affects 7-year mortality in older adults. METHODS We analyzed data from a nationally representative sample of people aged 65 years and over, participating in the 2001 National Health Interview Survey in Taiwan. A total of 1873 participants were followed through 2002-2008, of whom 286 (15.3%) had a history of diabetes confirmed by a medical professional. Participants were divided into three functional status groups: (1) high functioning-no limitations involving activities of daily living (ADLs), instrumental activities of daily living (IADLs), or physical functioning; (2) low functioning-limitations in one or more ADLs; (3) middle functioning-all participants in between groups 1 and 2. RESULTS The crude mortality rate was 52.7 per 1,000 person-years in those with diabetes and 34.1 per 1,000 person-years in those without diabetes. After adjustment for other factors, diabetes alone was not associated with an increased mortality risk in those with high functioning. However, diabetes alone had a hazard ratio (HR) for mortality of 1.90 (95%CI = [1.02-3.53]) in those with middle functioning and 3.67 (95%CI = [1.55-8.69]) in those with low functioning. The presence of diabetes and one or more other chronic conditions was associated with a HR for mortality of 2.46 (95%CI = [1.61-3.77]) in those with middle functioning and 4.03 (95%CI = [2.31-7.03]) in those with low functioning. CONCLUSIONS Our results indicate that diabetes is not associated with increased mortality in those with high functioning. There was a gradient effect of functional decline on mortality in individuals with diabetes. Additionally, among participants with other chronic conditions, functional decline was associated with a greater burden of mortality in older adults with diabetes. These findings highlight the critical importance of the prevention of cardiovascular disease morbidity and the maintenance of functional abilities in order to reduce mortality risk in older adults with diabetes.

Abstract
BACKGROUND research on life expectancy has demonstrated the negative impact of disability on the health of older adults and its differential effects on women as evidenced by their higher disabled life expectancy (DLE). The goal of the present study was to investigate gender differences in total life expectancy (TLE), disability-free life expectancy (DFLE), and DLE; examine gender differences on personal care assistance among older adults in São Paulo, Brazil; and discuss the implications for public policies. METHODS the sample was drawn from two waves (2000, 2006) of the dataset of Salud, Bienestar, y Envejecimiento, a large longitudinal study conducted in São Paulo (n = 2,143). The study assessed disability using the activities of daily living (ADL). The interpolation of Markov Chain method was used to estimate gender differences in TLE, DLE, and DFLE. FINDINGS TLE at age 60 years was approximately 5 years longer for women than men. Women aged 60 years were expected to live 28% of their remaining lives-twice the percentage for men-with at least one ADL disability. These women also lived more years (M = 0.71, SE = 0.42) with three or more ADL disabilities than men (M = 0.82, SE = 0.16). In terms of personal care assistance, women received more years of assistance than men. CONCLUSION among older adults in São Paulo, women lived longer lives but experienced a higher and more severe disability burden than men. In addition, although women received more years of personal assistance than men, women experienced more unmet care assistance needs.

Abstract
BACKGROUND New diabetes medications introduced over the last decade have led to changes in diabetes treatment recommendations for the increasing number of elderly patients with diabetes. It is, however, not clear whether these changes are accompanied by changes in prevalence of comorbid geriatric syndromes. OBJECTIVE To determine whether changes in diabetes treatment between 1993/1994 and 2004/2005 were accompanied by changes in prevalence of geriatric syndromes in Mexican Americans aged 75 years and older. METHODS Data from the Hispanic Established Population for the Epidemiologic Study of the Elderly were used. Participants aged 75 years and older with diabetes in 1993/1994 (n = 284) and in 2004/2005 (n = 324; new cohort added in 2004/2005) were included in the analyses. Medication use and geriatric syndromes prevalence rates were estimated and compared using descriptive and univariate statistics for continuous variables and contingency tables (chi(2)) for categorical variables. RESULTS Older Mexican Americans with diabetes in 2004/2005 were more likely to be taking 2 or more oral diabetes medications than were those in the 1993/1994 cohort; most of the drugs taken by the 2004/2005 cohort were the newly introduced oral diabetes medications. Use of insulin as sole diabetes therapy decreased from 20.3% in the 1993/1994 cohort to 7.5% in the 2004/2005 cohort. The 2004/2005 cohort reported longer diabetes duration and higher prevalence of obesity and hypertension; they were also more likely than the 1993/1994 cohort to have more geriatric syndromes: pain, arthritis, incontinence, and self-reported activities of daily living disability. No significant differences exist between the 2 cohorts in objective measures of cognitive and physical function. CONCLUSIONS Older Mexican Americans with diabetes in 2004/2005 used more of the newer diabetes medications and less insulin compared to the 1993/1994 cohort. The prevalence rates of geriatric syndromes were higher in the 2004/2005 cohort. Our findings suggest that screening for and treating comorbid geriatric syndromes is increasingly important for optimal geriatric diabetes care.

Diabetes, functional ability, and self-rated health independently predict hospital admission within one year among older adults: a population based cohort study. Arch Gerontol Geriatr 2010; 52:147-52.

Abstract
The aims of the present study were to determine the relationships among diabetes, functional ability and self-rated health, and whether they predict subsequent hospital admission in a representative sample of older adults. We conducted a prospective study on persons aged 65 and above (N=2064) who participated in the National Health Interview Survey in Taiwan, 2001. A total of 1609 participants consented to data linkage and were successfully linked to 2002 National Health Insurance claims data. Functional ability was defined as the ability to perform six activities of daily living (ADL). After adjustment for potential confounders, older adults with diabetes were significantly more likely to have ADL limitation and worse self-rated health and had an increased risk of hospitalization. Diabetes, ADL limitation and worse self-rated health all independently predicted hospital admission within one year. Older adults with diabetes, ADL limitation and worse self-rated health are important target populations for interventions aimed at preventing hospitalization.

Abstract
OBJECTIVE To examine the association between frailty status and incidence of disability among non-disabled older Mexican Americans. DESIGN A 10-year prospective cohort study. SUBJECTS A total of 1645 non-institutionalized Mexican Americans aged 67 years and older from the Hispanic Established Population for the Epidemiological Study of the Elderly (H-EPESE), who reported no limitation in activities of daily living at baseline. METHODS Frailty was defined as meeting 3 or more of the following components: (i) unintentional weight loss of > 2.26 kg; (ii) weakness (lowest 20% in hand grip strength); (iii) self-reported exhaustion; (iv) slow walking speed; and (v) low physical activity level. Socio-demographic factors, Mini Mental State Examination, medical conditions, body mass index, and self-reported activities of daily living were obtained. RESULTS Of the 1645 non-disabled subjects at baseline, 820 (50%) were not frail, 749 (45.7%) were pre-frail, and 71 (4.3%) were frail. The hazard ratio of activities of daily living disability at 10-year follow-up for pre-frail subjects was 1.32 (95% confidence interval 1.10-1.58) and 2.42 (95% confidence interval 70-3.46) for frail subjects compared with not frail subjects. This association remained statistically significant after controlling for potential confounding factors at baseline. CONCLUSION Pre-frail and frail status in older Mexican Americans was associated with an increased risk of activities of daily living disability over a 10-year period among non-disabled subjects.

Abstract
AIMS We aimed at determining the associations of type 2 diabetes (T2DM) and of angiographically determined coronary artery disease (CAD) with impaired mobility. METHODS We enrolled 747 consecutive patients undergoing coronary angiography for the evaluation of stable CAD. Mobility was assessed by the standardized timed-up-and-go (TUG) test, a functional test of physical performance. RESULTS Mobility was impaired (TUG time >10s) in 199 (26.6%) patients. The proportion of subjects with impaired mobility was higher among patients with T2DM than among non-diabetic individuals (40.2% vs. 22.0%; p<0.001), whereas it did not differ significantly between patients with significant coronary stenoses >or=50% and those without such lesions (p=0.802). Multivariate adjustment in logistic regression analyses confirmed that T2DM (adjusted odds ratio (OR)=2.05 [95% CI 1.35-3.11]; p=0.001) but not the presence of significant coronary stenoses (adjusted OR=0.81 [0.55-1.21]; p=0.306) was independently associated with impaired mobility. CONCLUSIONS T2DM but not coronary atherosclerosis is an independent determinant of impaired mobility in the high risk population of angiographied coronary patients. Mobility enhancing exercise programs are needed for diabetic coronary patients.

Abstract
The purpose of this study was to establish prevalence and five-year incidence, and explore functional decline among older Mexican Americans with Parkinson's disease (PD). Using data from the Hispanic EPESE, baseline characteristics were compared across PD response profiles. Weighted generalized estimating equations (GEE) modeled the association between PD and outcomes. Prevalence was 1.30%; incidence at wave 4 was 1.18%. Those with prevalent PD had worse function than those without PD at each wave. Progressive functional decline across time was observed among those with PD. Older Mexican Americans with PD often live in the community, and those who provide care for them may be overburdened.

Abstract
OBJECTIVE To explore the nature of functional impairment in older people with diabetes. RESEARCH DESIGN AND METHODS A population-based case-control study with detailed assessment of diabetes and functional status was undertaken. RESULTS Altogether, 403 case subjects and 403 matched control subjects were studied (median age 75 years, 51% female). Subjects with diabetes had more comorbidities than control subjects (mean 2.5 vs. 1.9, P < 0.0001) and were more likely to have severe functional impairment (4 vs. 1%, Barthel score <5, P < 0.001). Health status pertaining to physical function was reduced in case subjects (SF36 60 vs. 40, P < 0.0001). In a multivariate model controlling for age, hypertension, cerebrovascular disease, chronic obstructive pulmonary disease, cancer, osteoarthritis, and dementia, diabetes remained significantly associated with mobility limitation (odds ratio 2.1, P < 0.001). CONCLUSIONS Older people with diabetes have considerable functional impairment associated with reduced health status. This population may benefit from comprehensive geriatric assessment and tailored diabetes management.

Abstract
BACKGROUND AND AIMS Obesity among older persons is rapidly increasing, thus affecting their mobility negatively. The aim of this study was to examine the association of high body mass index (BMI) with walking limitation, and the effect of obesity-related diseases on this association. METHODS In a representative sample of the Finnish population of 55 years and older (2055 women and 1337 men), maximal walking speed, chronic diseases, and BMI were ascertained in a health examination. Walking limitation was defined as maximal walking speed of less than 1.2 m/s or difficulty in walking 500 meters. To analyze the effects of chronic conditions, smoking, marital status, and education on BMI class differences in walking limitation, covariates were sequentially adjusted in logistic regression analyses. RESULTS In women, an increasing gradient in the age-adjusted risk of walking limitation was observed with higher BMI: overweight (OR 1.47, 95% CI 1.10-1.96), obese (OR 2.77, 95% CI 2.01-3.82), and severely obese (OR 5.80, 95% CI 3.52-9.54). In men, the risk was significantly increased among the obese (OR 1.63, 95% CI 1.04-2.55) and severely obese (OR 4.33, 95% CI 2.20- 8.53). After adjustment of multiple covariates, the association remained significant among the obese (OR 1.99, 95% CI 1.38-2.86) and severely obese women (OR 3.64, 95% CI 2.12-6.26), as well as severely obese men (OR 2.78, 95% CI 1.30-5.95). Knee osteoarthritis in women and diabetes in men contributed most to the excess risk of walking limitation among obese persons, 18 and 32% respectively. CONCLUSIONS Obesity increases the risk of walking limitation, independent of obesity-related diseases, smoking, marital status, and education, especially in older women. The results of this study emphasize the importance of maintaining normal body weight, in order to prevent obesity-related health risks and loss of functioning in older age.

Abstract
BACKGROUND The older Hispanic population of the U.S. is growing at a tremendous rate. While ethnic-related risk and complications of diabetes are widely-acknowledged for older Hispanics, less is known about how health related quality of life is affected in this population. METHODS Cross-sectional study assessing differences in health related quality of life between older Mexican Americans with and without diabetes. Participants (n = 619) from the Hispanic Established Population for the Epidemiological Study of the Elderly were interviewed in their homes. The primary measure was the Medical Outcomes Study Short Form (SF-36). RESULTS The sample was 59.6% female with a mean age of 78.3 (SD = 5.2) years. 31.2% (n = 193) of the participants were identified with diabetes. Individuals with diabetes had significantly (F = 19.35, p < .001) lower scores on the Physical Composite scale (mean = 37.50, SD = 12.69) of the SF-36 compared to persons without diabetes (mean = 43.04, SD = 12.22). There was no significant difference between persons with and without diabetes on the Mental Composite scale of the SF-36. CONCLUSION Diabetes was associated with lower health related quality of life in older Mexican Americans. The physical components of health related quality of life uniformly differentiated those with diabetes from those without, whereas mental component scores were equivocal.

Abstract
To implement preventive policies of disability in older diabetic people, the role of diabetes in the disablement process should be investigated. Diabetes mellitus is consistently associated with a higher prevalence of disability at all states, as well as with a progression in disability states and may be considered as a brake on recovery. This association is partially explained by existing complications, associated conditions (obesity, depression, arterial hypertension) treatment burden, and other social characteristics (lower income, lower educational level). Finally, in the disablement process, the role of altered muscle metabolism due to diabetes, aging, nutrition and sedentary lifestyle may represent a major target for interventions to improve functions and potentially activities in elderly people.

Abstract
We are approaching an epidemic of diabetes in the elderly. This epidemic and its associated complications will have a significant impact on quality of life in this age group. Recent studies suggest that diabetes can be prevented in a large number of patients with appropriate interventions. It seems that diabetes in this age group is metabolically distinct. As a result, the approach to therapy in the elderly differs from that in younger patients. Unfortunately, we still have huge gaps in our understanding of the pathogenesis and treatment of diabetes in the aged, and further studies are needed urgently.
