There is increasing awareness of the detrimental health impact of frailty as well as malnutrition on older adults. The purpose of this analysis was to examine associations between measures of frailty and nutritional status in a sample from the More-2-Eat project (M2E), which focuses on improving nutrition care in Canadian hospitals.

Measures of frailty were handgrip strength (HGS) and the five-meter timed walk (5m). Nutritional status was measured by the SGA. A chi-square was used to test the associations between SGA (A vs. B/C) and 5m (>6 seconds(s)) and a Kruskal-Wallis test was used to compare SGA to continuous HGS (n=276) and 5 m values (n=123).

The median HGS and 5m scores were 19.0 kg (SD=12.4) and 6.7 s (SD=6.2) respectively. Of all the patients who had an SGA assessment completed, 59% (185/316) were identified to be malnourished (B/C), and ~43% (53/123) were found to be both malnourished and frail based on walking speed. Five meter, either using the >6 s cut-point or continuous values, was not significantly different across SGA categories (A=10.3 s vs. B/C= 10.0 s). However, HGS was significantly different (p<0.026) across SGA categories (A= 19.6 kg vs. B/C= 17.2 kg). 

In this sample, HGS values were significantly associated with malnutrition. Less than 50% of those who completed HGS also completed the 5m. HGS may be a useful measure to conduct with SGA to describe frailty comorbidity with malnutrition. Future work on HGS cut-points to establish frailty levels in an acute care population are needed.
