RESUMEN

INTRODUCTION: Hip fractures are very common injuries in elderly patients and are associated with increased mortality. OBJECTIVE: To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program. METHODS: We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables. RESULTS: Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001). CONCLUSIONS: Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

RESUMEN

The early identification of seniors at high risk of geriatric syndromes is fundamental for targeting interventions to those who most need them. To date, the predictive value of the Short Physical Performance Battery (SPPB) for multifactorial clinical conditions has not been clearly established. Thus, the aim of the present study was to determine whether the SPPB could identify frailty and predict geriatric syndromes in community-dwelling older adults. Participants comprised men and women aged 60 years and older who participated in the Health and Well-being and Aging Survey in Colombia 2015 (n=4125, 57.6% women). A structured interview was administered to obtain socio-demographic data which included age, sex, ethnicity, socioeconomic status, and urbanicity. The study included the measurement of body mass, grip strength, SPPB, Lawton´s instrumental ADL scale, specific subjective memory complaints (SSMC), frailty phenotype (Fried and FRAIL Scale), and self-reported falls, geriatric syndromes and/or medical conditions. ROC analysis was used to examine the ability of the SPPB test to predict frailty and geriatric syndromes. The cutoff that maximized both sensitivity and specificity for the frailty phenotype was 8 points or below for men and 7 points or below for women. These cutoff values significantly predicted four geriatric syndromes in descending order: mild dementia (♂ ORajus 3.34, and ♀ ORajus 2.79), low grip strength (♂ ORajus 1.98, and ♀ ORajus 2.45), falls (♂ ORajus 1.39, and ♀ ORajus 1.49), and SSMC (♂ ORajus 1.39). In summary, the main finding of the present study was that SPPB score (i.e., ≤ 8 ♂ and ≤ 7 ♀) seems to be a useful measure for identifying the physical frailty phenotype and predicting geriatric syndromes in community-dwelling older adults.

RESUMEN

BACKGROUND: Frailty is a clinical state defined as an increase in an individual's vulnerability to developing adverse health-related outcomes. OBJECTIVES: We propose that healthy behaviors could lower the incidence of frailty. The aim is to describe the association between healthy behaviors (physical activity, vaccination, tobacco use, and cancer screening) and the incidence of frailty. DESIGN: This is a secondary longitudinal analysis of the Mexican Health and Aging Study (MHAS) cohort. SETTING: MHAS is a population-based cohort, of community-dwelling Mexican older adults. With five assessments currently available, for purposes of this work, 2012 and 2015 waves were used. PARTICIPANTS: A total of 6,087 individuals 50-year or older were included. MEASUREMENTS: Frailty was defined using a 39-item frailty index. Healthy behaviors were assessed with questions available in MHAS. Individuals without frailty in 2012 were followed-up three years in order to determine their frailty incidence, and its association with healthy behaviors. Multivariate logistic regression models were used to assess the odds of frailty occurring according to the four health-related behaviors mentioned above. RESULTS: At baseline (2012), 55.2% of the subjects were male, the mean age was 62.2 (SD ± 8.5) years old. The overall incidence (2015) of frailty was 37.8%. Older adults physically active had a lower incidence of frailty (48.9% vs. 42.2%, p< 0.0001). Of the activities assessed in the adjusted multivariate models, physical activity was the only variable that was independently associated with a lower risk of frailty (odds ratio: 0.79, 95% confidence interval 0.71-0.88, p< 0.001). CONCLUSIONS: Physically active older adults had a lower 3-year incidence of frailty even after adjusting for confounding variables. Increasing physical activity could therefore represent a strategy for reducing the incidence of frailty. Other so-called healthy behaviors were not associated with incident frailty, however there is still uncertainty on the interpretation of those results.

RESUMEN

BACKGROUND AND OBJECTIVE: Muscular dysfunction and cognitive impairment are both disabling states, affecting especially the elderly. Thus, are important subjects of research. Our goal is to describe the association between these two entities in the elderly. METHODS: This is a secondary analysis from the SABE 2012 Bogota survey, which is a cross-sectional study. We define muscular dysfunction as an abnormal result in gait speed and/or handgrip strength tasks. Cognitive impairment was defined as an abnormal result in Mini Mental State Examination. Other independent variables were measured. RESULTS: A total of 1,564 older adults were included in the analysis. Cognitive impairment showed statistically significant association with both low handgrip strength (OR: 2.25; CI 1.52 - 3.33) and low gait speed (OR: 2.76; CI 1.83 - 4.15) in the adjusted model. CONCLUSION: In older adults, muscular dysfunction is associated with cognitive impairment. New studies should address the causality and temporality of this relationship.
