Evaluating Maturity by Using Mid Upper Arm Circumference among Neonates at Salahadeen General Hospital

Abstract

Background:   Anthropometry   is   the   single   most   easily   available, universally applicable, does not need expertise, economical, and non- invasive method of assessing body composition. It reflects both the health and  nutrition  of  human  body  and  predicts  performance,  health,  and survival. Aim of the present study evaluating the efficacy of mid-arm circumference in assessing birth weight and maturity among new born Methodology:  A  cross  sectional  study  done  in  Salah  Aldeen  general hospital in the Tikrit  city during the period from the (1st   November 2021 to 1st April 2022). During the period of the study had a total of 200 neonates were selected randomly. Each newborn was examined and mid upper arm circumference was measured, birth weight was measured with a calibrated digital weighing scale to the nearest 10 g.
Results: Most of the preterm babies had mid upper arm circumference  of ≤9.25 cm 47(90.4%) significantly higher than the full-term babies most of them had mid upper arm circumference  of >9.25 cm 126(85.1%). The mid upper arm circumference  is good parameter for diagnosing of prematurity with sensitivity of 90.4%, specificity (85%) and accuracy of the test was (87%).  The  PPV  for  diagnosing  low  prematurity  was  (68%)  and  the negative predictive value was (96.2%). Most of the Low birth weight babies had MUAC of ≤9.25 cm 53(93 %) while the Normal birth weight babies most of them had MUAC of >9.25  cm 127(88.8%)  this relation was statistically significant.
Conclusions: Mid upper arm circumference could be used as a diagnostic tool to identify low birth weight and preterm newborns needing extra care when taken at birth and up to day 7 of life.
