Description
Summary:Introduction: The aim of this study was to determine the trend of head circumference as predictor of microcephaly among term infants born in a teaching hospital in Malaysia from 2011 to 2015. Methodology: This was a cross-sectional study using data from the electronic birth census. The independent variables were mothers' age and height, parity, birth weight and birth length. All term newborns, both alive and stillbirth, with 37-41 completed gestational weeks, and a birth weight of at least 500 g was extracted from the census. Results: A total of 26,503 newborns fulfilled the inclusion criteria (13,655 males, 12,840 females). The mean head circumferences for male and female newborns were 32.93 cm ([+ or -] SD 1.32) and 32.56 cm ([+ or -] SD 1.31). The average head circumference for Malaysian newborns was found to be smaller than the World Health Organization Standard Growth Chart for Term Infant. A total of 17.6% (n=4,669) of the total samples were observed to have microcephaly. Among them, 73.2% (n=3,419) were non-proportionate microcephaly with normal birth weight of 2.5kg and above. Bivariate analyses showed that all independent variables were significant predictors of microcephaly. Both simple and multiple logistic regressions demonstrated that low birth weight was the most significant predictors for microcephaly (adjusted OR 12.14, 95% CI 10.80, 13.65). Conclusion: There is an increasing trend of microcephaly across the years and the low birth weight was noted as the main predictor of microcephaly. Future studies are needed to determine the possible cause of increasing microcephaly by controlling for birth weight and gestational age of the neonates.
