ABSTRACT

BACKGROUND:

Previous studies have shown a relationship between calf circumference (CC) and outcomes in hospitalized patients.

AIMS:

To investigate the relationship between CC and clinical and nutritional outcomes in older in-patients (OiP) in a surgery ward.

METHODS:

This was a cross-sectional study with 417 OiP in a surgery ward. Clinical variables, anthropometry, and nutritional screening instruments such as subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening (NRS) were used in the investigation. The tests Pearson’s chi-square, Mann-Whitney, Kruskal-Wallis, and Spearman’s coefficient, and multiple linear regression analyses were used to review the factors associated with CC.

RESULTS:

Lower CC values were found in the age group 80 years and over (p<0.0001), presence of complications (p=0.0269), NRS (p<0.0001), SGA (p<0.0001), and MNA (p<0.0001). Gender (p=0.0011; partial R²=0.01151), age (p=0.0002; partial R²=0.06032), body mass index (p≤0.0001; partial R²=0.40820), and arm circumference (p≤0.0001; partial R²=0.11890) are variables that together were associated with CC. There was also a relationship between SGA (p=0.0166; partial R²=0.00605) and absence of complications during hospitalization (p=0.0047; R²=0.01154) with CC.

CONCLUSIONS:

Gender, age, body mass index, and arm circumference were jointly associated with CC, in addition to SGA and absence of complications. The CC is a relevant indicator for OiP in the clinical practice.
