Introduction:
In Mini-Nutritional Assessment-Short Form (MNA-SF) test, a practical and reliable alternative parameter is still necessary for patients with difficult body mass index evaluation. We aimed to show whether or not handgrip strength may be used instead of body mass index (BMI) in MNA-SF test.
Materials And Methods:
MNA-SF test scores, calf circumferences (CC), handgrip strength (HGS), and BMI of 191 patients were evaluated. The first one of calculated MNA-SF tests was with BMI, the second one with CC, and the last one with HGS. Zero point was given if CC was <31 cm and 3 points were given if CC was ≥31 cm. Zero, 1, 2, and 3 points were given if the loss of HGS when compared to expected HGS were ≥%60, from ≥%30 to <%60, from ≥%10 to <%30, and <%10 or greater than expected HGS, respectively. MNA-SF scores and nutritional status according to these three measures were compared.
Results:
Mean age and median MNA-SF scores of the patients were 75±7.6 years and 12 points (min-max: 0-14) respectively. There were strongly positive correlations between MNA-SF scores with BMI and CC, with BMI and HGS, and with CC and HGS (r=0.938 p<0.001, r=0.938 p<0.001, r=0.914 p<0.001, respectively). Substantial agreement in nutritional status of the patients were seen between MNA-SF groups with BMI and CC, with CC and HGS, and with BMI and HGS (kappa: 0.795 p<0.001, kappa: 0.709 p<0.001, and kappa: 0.760 p<0.001, respectively).
Conclusions:
HGS might be considered instead of BMI in MNA-SF test to assess nutritional status of geriatric patients.
