M N ENTRE sarcopenia , DESNUTRICI N,MOVILIDAD F SICA Y ACTIVIDADES B SICAS DE LA VIDA DIARIA EN UN GRUPODE ANCIANAS DE LA CIUDAD DE M XICOR esumenAntecedentes:La sarcopenia es un s ndrome geri tricoque afecta el estado funcional y la movilidad de losancianos.

2 Objetivo:Identificar la prevalencia de sarcopenia ydesnutrici n, y evaluar la asociaci n entre sarcopenia ymovilidad, y sarcopenia y actividades b sicas de la vidadiaria (ABVD), en un grupo de mujeres ancianas. Sujetos y m todos:Un estudio de corte transversal, fuellevado a cabo en pacientes que asist an a un servicio degeriatr a en un hospital p blico en la ciudad de M sarcopenia fue identificada aplicando la ecuaci n deBaumgartner para obtener el ndice de masa muscularesquel tica apendicular (IMEA) y la desnutrici n fuediagnosticada usando la evaluaci n m nima del estado denutrici n (MNA).

3 El cuestionario de SENECA y el ndicede Katz fueron usados para evaluar movilidad y ABVD,respectivamente. An lisis estad stico: un modelo deregresi n lineal fue construido usando IMEA comovariable dependiente y SENECA, y la calificaci n deABVD como variables independientes, ajustado por edad. Resultados:90 mujeres con un promedio de edad de78,2 ( 6,8) a os fueron estudiadas. La desnutrici n fueidentificada en 15,5% de las pacientes. La prevalencia desarcopenia fue de 41,1%. Las pacientes con sarcopeniapresentaron una alta prevalencia de desnutrici n (p <0,001).

4 La sarcopenia se asoci con dificultad para subirescaleras (OR = 2,63, p = 0,03), ajustada por edad. Lamovilidad se asoci con sarcopenia ; en el grupo sin sarco-penia el promedio de la escala fue 16,3, y con sarcopenia18,3, (p = 0,04). En relaci n a ABVD, 64,9% de laspacientes con independencia intermedia/dependenciaten a sarcopenia , mientras que 35,1% con independenciatotal present sarcopenia , (p < 0,001). Conclusiones:Las pacientes con sarcopenia ten an unamayor prevalencia de desnutrici n. La sarcopenia seasoci con dificultad para la movilidad, particularmentesubir escaleras.

Objective:To identify the prevalence of sarcopenia andundernutrition, and to assess the association betweensarcopenia and mobility , and sarcopenia and basic activi-ties of daily living (ADL) in a group of elderly women. Subjects and methods:A cross-sectional study wasperformed in patients attending a geriatric service at agovernment hospital in Mexico City. sarcopenia was identi-fied applying Baumgartner s equation by obtaining skeletalmuscle mass index (SMI) and undernutrition was diag-nosed using mini-nutritional assessment instrument(MNA).

6 The SENECA questionnaire and Katz index wereused to evaluate mobility and ADL, respectively. Statisticalanalysis: lineal regression models were constructed fittingSMI as a dependent variable and SENECA, and ADLscores as independent variables, adjusted for age. Results:90 women with a mean age of ( ) werestudied. undernutrition was identified in of thepatients. The prevalence of sarcopenia was Patientswith sarcopenia presented a high prevalence of undernutri-tion (p < ). sarcopenia was associated with difficulty inclimbing stairs (OR = , p = ), adjusted for age.

7 Themobility score was associated with sarcopenia , in the groupwithout sarcopenia the mean score was , and withsarcopenia it was , (p = ). Regarding ADL, ofthe patients with intermediate independence and depen-dence had sarcopenia , while with total independencepresented sarcopenia (p < ). Conclusions:The elder women with sarcopenia had ahigher prevalence of undernutrition . sarcopenia wasassociated with difficulties in mobility , particularly diffi-culties in climbing stairs.(Nutr Hosp. 2013;28:514-521) words: sarcopenia . undernutrition .

9 It is a syndrome characterized byprogressive and generalized loss of skeletal mass,strength, and muscle sarcopenia is associ-ated with weakness, loss of independence, disability,higher risk of falls, and also, a decrease in quality ,3,4 The significant clinical impact of sarcopeniaand its high costs both direct and indirect that thiscondition generates, in an aging society, emphasizesthe need of health care systems to focus on this geri-atric epidemiological data available indicates that theprevalence of sarcopenia varies widely, this variation isnot only related to the population being studied, but alsofor the diagnostic criteria that is selected by study known as Rosetta, comparedthe muscle mass distribution of young versus elderlypeople and it was one of the first reports that showed adecrease in skeletal muscle mass with fromthis study has been used as a reference for defining thecut-off point of the skeletal muscle mass index (SMI),which is the value of SMI corresponding to < 2 SD inyoung the results of the Rosettastudy, Baumgartner et al.

10 ,9 developed an equation to esti-mate both the appendicular skeletal muscle mass (ASM)and the relative appendicular skeletal muscle mass index[ASM (kg)/height (m2)]. The decline in SMI is associ-ated with the reduction of muscle strength, which in turnis a good predictor of musclemass is a vital tissue that must be preserved, particularlyin the elderly, in order to avoid serious consequences inthe nutritional and health status of this ,12 Clinicaland epidemiological studies have shown that there is adecrease in food intake in older adults; they eat less andhave a poor diet, which increases the risk of negative feedback mechanism takes place andundernourished elders become sick more often, and sickelders become undernourished with greater prevalence of undernutrion is higher in institutional-ized elderly patients as compared with community-dwelling In Mexico, undenutrition in elderlypeople is a common finding in hospital ,16 Onlya few studies on sarcopenia have considered the associa-tion of this condition with undernutrition , mobility , andactivities of daily living (ADL).
