Artigo Low calf circumference adjusted for body mass index is associated with prolonged hospital stay(The American Journal Of Clinical Nutrition, 2023-02) Fayh, Ana Paula Trussardi; Sousa, Iasmin Matias de; Lima, Júlia; Gonzalez, Maria Cristina; Prado, Carla M.; Silva, Flávia MoraesBackground: Calf circumference (CC) is of emerging importance because of its practicality, high correlation with skeletal muscle, and potential predictive value for adverse outcomes. However, the accuracy of CC is influenced by adiposity. CC adjusted for BMI (BMI-adjusted CC) has been proposed to counteract this problem. However, its accuracy to predict outcomes is unknown. Objectives: To evaluate the predictive validity of BMI-adjusted CC in hospital settings. Methods: A secondary analysis of a prospective cohort study in hospitalized adult patients was conducted. The CC was adjusted for BMI by reducing 3, 7, or 12 cm for BMI (in kg/m2) of 25–29.9, 30–39.9, and ≥40, respectively. Low CC was defined as ≤34 cm for males and ≤33 cm for females. Primary outcomes included length of hospital stay (LOS) and in-hospital death, and secondary outcomes were hospital readmissions and mortality within 6 mo after discharge. Results: We included 554 patients (55.2 ± 14.9 y, 52.9% men). Among them, 25.3% presented with low CC, whereas 60.6% had BMI-adjusted low CC. In-hospital death occurred in 13 patients (2.3%), and median LOS was 10.0 (5.0–18.0) d. Within 6 mo from discharge, 43 patients (8.2%) died, and 178 (34.0%) were readmitted to the hospital. BMI-adjusted low CC was an independent predictor of LOS ≥ 10 d (odds ratio = 1.70; 95% confidence interval: 1.18, 2.43], but it was not associated with the other outcomes. Conclusions: BMI-adjusted low CC was identified in more than 60% of hospitalized patients and was an independent predictor of longer LOS
