dc.description.abstractThe relevance of using literature derived birth weight for gestational age centile charts for the Maltese population is debatable. The study set out to develop national weight for gestational age centile charts and compare these to other populations. Method: Anonymised birth weight for gestational age data with relevant maternal and neonatal observations over the period 1995-2009 were obtained from national statistics. The formats were standardised and imported into an SQL database that enabled filtration for single live births and grouping by sex. The data was scrutinized manually for obvious keying errors. The best estimate of gestational age from the last menstrual period (LMP) and expected date of delivery (EDD) was selected using established guidelines. A Box-Cox gamma transform was used to fit the model and generate separate centile charts. The data was compared to previous birth weight data reported in Maltese newborns in previous decades and to data from other countries. Results: A total of 58,899 neonates were included in the study and birth weight for gestational age centile charts were generated between 23 and 42 weeks of gestation using Revolution R with VGAM. There has been a statistically significant gradual fall in mean birth weight in Maltese newborns over the last four decades. There are also statistically significant differences between the Maltese data and those from other countries. Conclusion: The observed differences make the use of national birth weight for gestational age centile charts desirable both for routine clinical assessment and epidemiological studies.en_GB
