ABSTRACT

Background: Middle Upper Arm Circumference (MUAC) is the circumference of the left upper arm, measured at the middle point between the tip of the shoul­der and the tip of the elbow (olecranon process and the acromium). MUAC is used for the assessment of nutritional status. It is a good predictor of mortality and in many studies, MUAC predicted death in children better than any other anth­ro­­­pometric indicator. This study aimed to validity of middle-upper arm cir­cum­­­ference as an indicator of nutritional status in patients with cancer under­going chemotherapy.

Subjects and Method: A cross-sectional study was conducted at Sultan Agung Is­lamic hospital, Semarang, Central Java. A sample of 52 cancer patients un­der­going chemotherapy was selected for this study. The independent variable was body mass index (BMI) served as the gold standard. The dependent variable was mid­dle upper arm circumference (MUAC). Both indicators were measured by an­thro­pometric measurement. Sensitivity and specificity were calculated to indicate va­lidity. BMI and MUAC scores were analyzed by Pearson correlation.

Results: MUAC had a strong and positive correlation with BMI (r= 0.76; p<0.001). In comparison with BMI, MUAC showed high sensitivity (94.7%) and mo­de­­rate specificity (75.8%).

Conclusion: MUAC is strongly correlated with BMI with high sensitivity and moderate specificity. It can be used as an indicator of nutritional status in cancer pa­tients undergoing chemotherapy.
