English abstract
Objectives:This study aimed to compare reference anthropometric measures of Omani neonates
with the international standard growth charts of the World Health Organization (WHO) in order to determine the
appropriateness of these growth charts to assess the growth of Omani neonates. Methods: This cross-sectional
study included all healthy full-term Omani neonates born between November 2014 and November 2015 at the
Sultan Qaboos University Hospital, Muscat, Oman. Birth weight, length and head circumference measurements
were identified and compared to those of the 2006 WHO growth charts. Results: A total of 2,766 full-term neonates
were included in the study, of which 1,401 (50.7%) were male and 1,365 (49.3%) were female. Mean birth weights
for Omani males and females were 3.16 ± 0.39 kg and 3.06 ± 0.38 kg, respectively; these were significantly lower
than the WHO standard measurements (P <0.001). Similarly, the mean head circumferences of Omani males and
females (33.8 پ} 1.27 cm and 33.3 پ} 1.26 cm, respectively) were significantly lower than those reported in the WHO
growth charts (P <0.001). In contrast, mean lengths for Omani males and females (52.0 پ} 2.62 cm and 51.4 پ} 2.64
cm, respectively) were significantly higher than the WHO standard measurements (P <0.001). Conclusion: The
WHO growth charts might not be appropriate for use with Omani neonates; possible alternatives should therefore
be considered, such as national growth charts based on local data.
