Diagnóstico da sarcopenia baseado em 5 pontos de corte para a força muscular e a associação com estado nutricional em idosos da comunidade

Abstract

The aim: to determine the frequency of sarcopenia according to five cutoff points for muscle strength and its association with nutritional status in community-dwelling elderly people. Method: Cross-section with 321 elderly people from community centers-Cuiabá-MT. The main variable was the frequency of sarcopenia and association with nutritional status. Sarcopenia was diagnosed by low muscle strength (palm grip strength - HGS; kgf) according to five cut-off points and by low calf circumference (CP; cm) and nutritional status by reduced mini nutritional assessment (MAN-r). Results: The median age was 69 years and 24.7% were not nourished. Sarcopenia ranged from 1.6 to 7.6%. This frequency was lower between the EWGSOP2 criterion and the EWGSOP (p=0.005), ESCEO and SDOC (p<0.001). The overlap of sarcopenia with non-nourished was 0.9% (EWGSOP2), 1.3% (AWGS), 2.5% (EWGSOP), 3.1% (SDOC) and 3.5% (ESCEO) with no difference between the five cut-off points (p>0.05). On the other hand, the non-nourished were almost 3.5 times more likely to have sarcopenia (OR=3.49; p=0.019) when the ESCEO criterion was used and almost 2.5 times (OR=2.43; p=0.037 ) times more for the SDOC. Conclusion: The frequency of sarcopenia ranged from 1.6 to 7.6% and the overlap with the diagnosis of malnourished occurred in 0.9 to 3.5%. The non-nourished elderly were almost 3.5 and 2.5 times more likely to have sarcopenia, respectively, according to ESCEO and SDOC.
