Mid‐upper arm circumference in hospitalized pediatric patients with cancer: Is there an association with malnutrition?

Abstract

AbstractBackgroundMalnutrition is common in children/adolescents with cancer. Mid‐upper arm circumference (MUAC) is recommended by the International Society of Pediatric Oncology for measuring nutrition status. The aim was to evaluate the nutrition status of pediatric patients with cancer and verify whether MUAC is associated with malnutrition and length of stay (LOS).MethodsThis was an observational study of patients aged 0–19 years with solid and hematological neoplasms. Data included anthropometric measurements of nutrition status by body mass index/age (BMI/A), weight/age, weight/height, height/age, MUAC, mid‐arm muscle circumference, triceps skinfold thickness (TSF), and biochemical measurements of characterizing inflammation (serum prealbumin level, serum albumin level, and C‐reactive protein [CRP]). Statistical tests such as the Student t test, Mann‐Whitney test, and Spearman correlation were employed to analyze the data. Logistic regression was used for multivariate analysis.ResultsOf 111 patients, 51.7% (n = 57) were male, and solid tumors were prevalent (76.6%, n = 85). The median age was 8.5 years. The anthropometric measurements of the arm revealed a higher prevalence of malnutrition when compared with anthropometric indices. According to the Spearman correlation, a high and positive correlation was observed between MUAC and BMI/A (ρ = 0.800 and P < 0.001). There was an association between MUAC, TSF, and high CRP with LOS (P = 0.025, P = 0.003, and P < 0.001, respectively). Patients with a MUAC (less than the fifth percentile) had almost 2.73 times the chance of having a prolonged LOS.ConclusionMUAC was a good parameter for the classification of nutrition status and the assessment of LOS in pediatric patients with cancer.
