ABSTRACT

Objetivo : Avaliar relações entre estado nutricional, sarcopenia e osteoporose em idosas.Sujeitos e métodos : Estudamos 44 mulheres, 67-94 anos, mediante miniavaliação nutricional (MAN), filtração glomerular (FG) corr. 1,73 m2, índice de massa corporal (IMC), circunferência da panturrilha e braquial (CP e CB), densidade mineral óssea e composição corporal, DXA (massa gorda – MG; massa magra – MM). Aferimos sarcopenia: IMM = MM MSS + MIS/altura2. Utilizamos o coeficiente de correlação de Pearson, e p < 0,05 como significativo.Resultados : MNA e IMM se correlacionaram positivamente com IMC, CP, CB e MG. A idade influenciou negativamente FG corr., IMC, MG, IMM e CP. Quatorze tinham história de fraturas osteoporóticas. O mais baixo T-score foi diretamente relacionado a MAN e MG.Conclusões : O envelhecimento acarretou o declínio da FG, MG e massa muscular; a circunferência da panturrilha e braquial refletiu estado nutricional e composição corporal; e as grandes influências na DMO foram estado nutricional e MG.

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 m2, 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/height2. 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.Arq Bras Endocrinol Metab. 2014;58(3):226-31.
