[Analysis of elderly outpatients in relation to nutritional status, sarcopenia, renal function, and bone density]. / Análise de idosos ambulatoriais quanto ao estado nutricional, sarcopenia, função renal e densidade óssea.

OBJECTIVES: To evaluate relationships between nutritional status, sarcopenia and osteoporosis in older women. SUBJECTS AND METHODS: We studied 44 women, 67-94 years, by mini-nutritional assessment (MAN), glomerular filtration corr. 1.73 m(2), body mass index (BMI), arm circumference and calf (CP and CB), bone mineral density and body composition, DXA (fat mass MG; lean MM). We gauge sarcopenia: IMM MM = MSS + MIS/height(2). We used the Pearson correlation coefficient, p < 0.05 as significant. RESULTS: MNA and IMM were positively correlated with BMI, CP, CB and MG. Age influenced negatively FG corr., BMI, FM, IMM and CP. Fourteen had a history of osteoporotic fractures. The lowest T-score was directly related to MAN and MG. CONCLUSIONS The aging caused the decline of FG, fat mass and muscle; the calf circumference, and brachial reflected nutritional status and body composition; and major influences on BMD were nutritional status and fat mass.
