Rationale: Calf circumference (CC) is a simple, non-invasive, and useful tool for evaluating the nutritional and muscular status of hospitalized patients, particularly those at risk of malnutrition or sarcopenia. Our aims is to determine muscle mass using CC upon admission in patients monitored by the Nutrition Unit of CAULE at 2024. Additionally, to assess whether CC values are associated with longer hospital stays.

Methods: A prospective study of hospitalized patients monitored by the Nutrition Unit of CAULE. Nutritional assessment was performed, including CC measurement adjusted for BMI upon admission. The association between low CC (<32 cm in men and <31 cm in women)¹ and the length of hospital stay was also evaluated.

Results: A total of 144 patients were included, 62.5% of whom were men, with a mean age of 67.6 years (SD 16.2). CC measurements were available for 125 patients. The main reasons for admission were oncological (27.3%), digestive (15.4%), surgical (15.4%), and hematological (11.4%) conditions. Among the patients, 40.3% were at risk of disease-related malnutrition, 38.2% and 16% met the GLIM criteria for severe and moderate malnutrition, respectively, and 5.6% had dysphagia. The mean weight was 66.1 kg (SD 16.4), BMI was 24.3 kg/m² (SD 5.8), and CC was 32.6 (SD 4.1) cm. Table 1 presents the hospital stay duration based on CC categorization as low or normal according to the defined cut-off points.

Conclusion: Nearly 30% of hospitalized patients had low CC values. In our sample, patients with low CC experienced longer hospital stays, although no statistically significant differences were observed, possibly due to sample size differences between groups.
