The authors investigate whether there is a correlation between mid-upper arm circumference (MUAC) and body mass index (BMI). The authors explored using MUAC as a low-resource alternative (or supplement) to BMI in assessing nutrition in adolescent populations. They conclude that using MUAC has the potential to provide simple, low-resource nutrition screening when BMI is not possible. However, more research with more nutritionally and demographically diverse populations is needed to better understand the nutritional status of adolescents and practical contribution of MUAC cut-offs.
