Síntomas depresivos y prevalencia de fragilidad en adultos mayores colombianos. Análisis secundario de la encuesta SABE Colombia 2015

Objetivo: Analizar la relación entre los síntomas depresivos y la prevalencia de fragilidad medida como fenotipo de fragilidad. Materiales y métodos: Estudio secundario de la encuesta SABE Colombia 2015. Se utilizaron las puntuaciones de la escala Yesavage como variable independiente, la prevalencia de fragilidad calculada con el fenotipo de fragilidad de Fried. Realizamos un análisis descriptivo y bivariado de la muestra, seguido de un análisis multivariado ajustando por variables de confusión. Resultados: Analizamos información de un total de 19 004 participantes mayores de 60 años, participantes sin deterioro cognitivo de la encuesta, a quienes se les administró la escala Yesavage. La media de edad fue 69.25 años, el 56 % de los participantes eran mujeres, la prevalencia de fragilidad fue del 12 % y se encontró síntomas depresivos en 57,4 % de la muestra. En el análisis multivariado encontramos asociaciones estadísticamente significativas entre las puntuaciones más altas de la escala Yesavage y la presencia de fragilidad (Yesavage 5-10) OR 1.20 (0.98-1.46) p valor 0.066 y (Yesavage >10) 2.05 (1.46-2.89) <0.001 después de ajustar por edad, sexo, comorbilidades, funcionalidad, escolaridad y estado marital Conclusiones: Nuestro estudio muestra asociaciones estadísticamente significativas entre la presencia de síntomas depresivos medidos con la escala Yesavage y la prevalencia de fragilidad según el índice de Fried. Aunque existe escasa evidencia en cuanto a la asociación de estas dos entidades en Latinoamérica, nuestros resultados son consistentes con estudios previos en la región.

Objetive: There is scarce evidence in Latin America that describes depression in the elderly population with fragility. The aim of this paper is to provide a better understanding of the relationship between depressive symptoms in elderly and the prevalence of frailty. Material and methods: We performed secondary analysis of the SABE Colombia 2015 survey. The Yesavage scale scores were used as an independent variable, the prevalence of frailty was estimated with the Fried fragility phenotype. We performed a descriptive and bivariate analysis of the sample, followed by a multivariate analysis adjusting for confounding variables. Results: We analyzed information from a total of 19,004 participants over 60 years of age, participants without cognitive impairment of the survey, who were administered the Yes-avage scale. The mean age was 69.25 years, 56 % of the participants were women, the prevalence of frailty was 12 % and depressive symptoms were found in 57.4 % of the sample. In the multivariate analysis we found statistically significant associations between frailty and the higher Yesavage scores (score 5-10) OR 1.20 (0.98-1.46) p valor 0.066 and (score> 10) 2.05 (1.46-2.89) <0.001 after adjusting for age, sex, comorbidities, functionality, schooling and marital status. Conclusions: Our study shows an independent relationship between depressive symptoms and frailty phenotype in the SABE Colombia 2015s survey There is lack of data and characterization of this population in Latin America regarding the relationship of these conditions, however our results are consistent with previous reports from this region.

Association of Malnutrition with Functional and Cognitive Trajectories in People Living with Dementia: A Five-Year Follow-Up Study.

BACKGROUND: In dementia, functional status depends on multiple factors in addition to cognition. Nutritional status is a potentially modifiable factor related to homeostasis and proper functioning of body systems and may contribute to cognitive and functional decline. OBJECTIVE: This paper aims to analyze the association of malnutrition with the course of cognitive and functional decline in people living with dementia. METHODS: This is an analysis of a longitudinal cohort study, the Dementia Study of Western Norway. Data of 202 patients diagnosed with mild dementia were analyzed; Alzheimer's disease (AD) (n = 103), Lewy body dementia (LBD) (n = 74), and other dementias (OD) (n = 25). Cognition was assessed with the Mini-Mental State Examination and functional decline through the activities of daily living included in the Rapid Disability Rating Scale. The Global Leadership Initiative on Malnutrition Index was used to determine nutritional status. Associations of nutritional status with cognitive and functional decline were evaluated through adjusted linear mixed models. RESULTS: At baseline, the prevalence of general malnutrition was 28.7%; 17.3% were classified as moderate malnutrition and 11.38% as severe malnutrition (there were no significant differences between AD and LBD). Malnutrition at diagnosis and over follow-up was a significant predictor of functional-decline, but not of cognitive decline. CONCLUSION: According to our results malnutrition was associated with faster functional loss but, not cognitive decline in older adults with dementia. A more comprehensive dementia approach including nutritional assessments could improve prognosis.

Association between physical activity and cognition in Mexican and Korean older adults.

INTRODUCTION: As the world's population ages, the prevalence of cognitive impairment associated with age increases. This increase is particularly pronounced in Asia and South-America. The objective of this study was to investigate separately the longitudinal association of physical activity and cognitive function in; older adults in Mexico and South Korea. MATERIALS AND METHODS: This is a secondary analysis of two surveys, The Mexican Health and aging Study (MHAS) (n = 5853) and Korean Longitudinal Study of aging (KLoSA) (n = 5188), designed to study the aging process of older adults living in Mexico and South Korea. Participants older than 50 years were selected from rural and urban areas achieving a representative sample. Physical activity was assessed using self-report. Cognition was assessed using Cross-Cultural Cognitive Examination (CCCE) and Minimental state examination (MMSE) in Mexico and South Korea respectively. Here we investigate the longitudinal association between physical activity and cognition during 3 years for MHAS and 4 years for KLoSA using multiple linear regression analyses. RESULTS: The prevalence of physical activity was 40.68 % in MHAS and 35.57 % in KLoSA. In the adjusted longitudinal multivariate analysis, an independent association was found between physical activity and MMSE score OR 0.0866 (CI 0.0266-0.1467 p-value 0.0047) in the Korean older adults, while there was no significant association in MHAS. CONCLUSIONS: Physical activity could have a protective effect on the cognitive decline associated with aging in the Korean population.

Asociación entre fuerza de prensión y comorbilidades: estudio SABE, Ecuador, 2009 / Association between Grip Strength and Comorbidities: SABE Ecuador 2009 Study / Associação entre força de preensão e comorbidades: estudo SABE, Equador, 2009

Resumen Introducción : el aumento de enfermedades crónicas ha motivado la creación de métodos de evaluación del adulto mayor que permitan estimar su estado general de salud. Entre estos, se ha propuesto la fuerza de prensión. El objetivo de este estudio fue buscar la asociación entre el número de comorbilidades y la fuerza de prensión. Materiales y métodos : se analizaron los datos del estudio SABE Ecuador 2009, un estudio transversal que incluyó una muestra probabilística y representativa de 5235 adultos mayores de 60 años o más. La variable dependiente fue el desempeño en la fuerza de prensión y la sumatoria de comorbilidades, como la variable independiente. Se realizó un modelo de regresión logística lineal para estimar asociaciones independientes. Resultados: de un total de 5235 personas, la media de la suma de comorbilidades fue 1.54 ± 1.36 y la media de la fuerza de prensión fue de 21.45 ± 9.37 kg. Se encontró una asociación negativa de la fuerza de prensión y la suma de comorbilidades, desde 0 comorbilidades -0.88, hasta más de 6 comorbilidades -3.52 (p < 0.05). Ninguna enfermedad por sí sola tuvo mayor asociación con la disminución de la fuerza muscular que el tener más de dos enfermedades concomitantes. Conclusiones: este estudio encontró una asociación lineal negativa entre la fuerza de prensión y la sumatoria de comorbilidades. Los resultados reportados abren la puerta para plantear nuevos estudios que permitan desarrollar herramientas de evaluación que beneficien a la población adulta mayor.

Abstract Introduction : The increase of chronic pathologies is a consequence of the demographic transition which represents a challenge for current societies. Concurrently this motivated the development of new methods for evaluating the elderly which allow estimating their health state of health, that amongst others include the grip strength. The objective of this study was to look for the association between the number of present comorbidities and the grip strength. Materials and Methods : We analyzed data from SABE Ecuador 2009 study, a cross-sectional study that includes a probabilistic and representative sample of 5235 older adults of 60 years or older living in the community. The dependent variable was the performance in the grip strength and the sum of comorbidities as the independent variable. A linear logistic regression model was used to estimate independent associations. Results : Out of a total of 5235 people, the mean of the sum of comorbidities was 1.54 ± 1.36, and the average of the grip strength was 21.45kg ± 9.37 kg. We found a negative linear association of the grip strength and the sum of comorbidities, from one comorbidity -0.88 up to more than six comorbidities -3.52 (p <0.05). No disease by itself had a higher association with the decrease in muscle strength than having two or more concomitant afflictions. Conclusions : This study found a negative association between grip strength and the presence of comorbidities. Our results open the door to propose new studies to develop assessment tools that benefit the elderly population.

Educational level and its Association with the domains of the Montreal Cognitive Assessment Test.

Objective: To explore the association between educational level and the scores obtained in each of the domains of the Montreal Cognitive Assessment test. Methods: This is a secondary analysis of the SABE/2012 Bogotá survey; a cross-sectional study including 2000 subjects aged ≥60years. The MoCA test was the dependent variable and was stratified by cognitive domains, incorrect answers and scores were considered. Educational level was assessed through years of formal education. Age, sex and selected medical conditions were also included to adjust the multivariate models. Bivariate analyses, fitted logistic and linear regression models were employed for analyzing association between these variables. Results: The proportion of incorrect answers increased as schooling years decreased and as age increased. In the multivariate analysis, visuospatial and executive function were the most affected domains. Educational level displayed less influence than age on short memory-recall task (standardized beta 0.19 vs -0.24). Educational level showed a greater influence than age on no-memory tasks (the sum of all other domains; standardized beta 0.50 vs -0.29). Conclusions: It seems logical to consider that performance in most domains of the MoCA is influenced by years of education. Therefore, low scores on these tasks could lead to low total MoCA scores and thus to bias and over diagnosis of cognitive impairment in patients with lower educational levels. Memory-recall domain is not affected much by education and applying it separately could be useful in patients with low educational level in whom we suspect memory impairment.
