RESUMO
OBJECTIVE: Describe the protocol sample and instruments of the Cognitive Aging Ancillary Study in Mexico (Mex-Cog). The study performs an in-depth cognitive assessment in a subsample of older adults of the ongoing Mexican Health and Aging Study (MHAS). The Mex-Cog is part of the Harmonized Cognitive Assessment Protocol (HCAP) design to facilitate cross-national comparisons of the prevalence and trends of dementia in aging populations around the world, funded by the National Institute on Aging (NIA). METHODS: The study protocol consists of a cognitive assessment instrument for the target subject and an informant questionnaire. All cognitive measures were selected and adapted by a team of experts from different ongoing studies following criteria to warrant reliable and comparable cognitive instruments. The informant questionnaire is from the 10/66 Dementia Study in Mexico. RESULTS: A total of 2,265 subjects aged 55-104 years participated, representing a 70% response rate. Validity analyses showed the adequacy of the content validity, proper quality-control procedures that sustained data integrity, high reliability, and internal structure. CONCLUSIONS: The Mex-Cog study provides in-depth cognitive data that enhances the study of cognitive aging in two ways. First, linking to MHAS longitudinal data on cognition, health, genetics, biomarkers, economic resources, health care, family arrangements, and psychosocial factors expands the scope of information on cognitive impairment and dementia among Mexican adults. Second, harmonization with other similar studies around the globe promotes cross-national studies on cognition with comparable data. Mex-Cog data is publicly available at no cost to researchers.
RESUMO
Osteosarcopenic obesity (OSO) is a condition associated with adverse outcomes in older adults. Since it is a condition which includes three tissues (obesity, sarcopenia and osteopenia/osteoporosis), it requires simultaneous and multidisciplinary clinical interventions to revert it. Until this moment, there have been published review articles only focused on nutrition or physical activity. However, we believe that assembling the existing evidence on potential treatments (nutritional intervention with micro- and macronutrients), physical activity, farmacological treatment for osteopenia/osteoporosis, possible farmacological treatment for sarcopenia, and, finally, psychological interventions focused on the treatment of psychiatric comorbidities (such as anxiety or depression) will help healthcare providers to improve the body composition of older adults.
La obesidad osteosarcopénica (OOS) es una condición que representa diversos desenlaces adversos en el adulto mayor. Al ser una condición que incluye tres tejidos (obesidad, sarcopenia y osteopenia/osteoporosis), se requiere de intervenciones clínicas simultáneas y multidisciplinarias para lograr revertirla. Hasta el momento, han sido publicados artículos de revisión enfocados solo a la nutrición y a la actividad física. Sin embargo, consideramos que es necesario reunir la evidencia del nivel nutricional (en cuanto a micro- y macronutrientes), de la actividad física habitual o personalizada, de los potenciales tratamientos farmacológicos para la sarcopenia, del actual tratamiento farmacológico para la osteopenia/osteoporosis y, por último, en torno a las posibles intervenciones psicológicas enfocadas a tratar la comorbilidad psiquiátrica (ansiedad o depresión) y directamente hacia la mejora de la composición corporal en adultos mayores.
