A secondary aim was to determine the accuracy of EFW by assessing the difference between EFW and actual birth weight.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a prospective cross\u2010sectional cohort study. Viable singleton pregnancies at 11\u201313\u2009weeks' gestation were recruited to undergo a single standardized fetal biometric scan after 20\u2009weeks. The gestational age at which the scan was performed was allocated randomly at the time of recruitment. EFW was predicted using both the Hadlock and INTERGROWTH\u201021<jats:sup>st<\/jats:sup> weight estimation model formulae. Population\u2010specific EFW references were constructed. <jats:italic>Z<\/jats:italic>\u2010scores were used to compare these references against the INTERGROWTH\u201021<jats:sup>st<\/jats:sup> and WHO international size references. Gestational\u2010age\u2010adjusted projection was used to assess the difference between EFW on the day of delivery and birth weight for fetuses having biometry scans \u2265\u200934\u2009weeks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fetuses of 970 participants had biometry scans. The median number of scans per gestational week was 48 (interquartile range, 43\u201353). <jats:italic>Z<\/jats:italic>\u2010score comparison indicated that the WHO 10<jats:sup>th<\/jats:sup>, 50<jats:sup>th<\/jats:sup> and 90<jats:sup>th<\/jats:sup> centiles of the EFW reference were consistently higher than the corresponding local centiles, whilst the INTERGROWTH\u201021<jats:sup>st<\/jats:sup> 10<jats:sup>th<\/jats:sup> centile was lower. Fewer than 2% of fetuses scanned at or after 34\u2009weeks would be considered as potentially large\u2010for\u2010gestational age, irrespective of which model was used to predict weight. Adopting the WHO international reference would result in approximately one in six fetuses being regarded as potentially small\u2010for\u2010gestational age, 50% more than the number determined using a population\u2010specific reference. Systematic errors of extrapolated EFW were similar, ranging from 5.5% to 7.4%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Centers seeking to use new references, such as the INTERGROWTH\u201021<jats:sup>st<\/jats:sup> and\/or WHO international references, as a means of determining whether a fetus is small\u2010 or large\u2010for\u2010gestational age, would be advised to assess the suitability of these references within their own population using standardized methodology.
