Abstract: Objective To determine appropriate reference ranges for evaluating local fetal head circumference(HC). Methods HC measurements of fetuses who accepted ultrasound detection from Sep?tember 2012 to December 2016 in our hospital were collected. Kappa value and Youden index were used to compare the consistency between the reference ranges and the actual data,and evaluate the sensitivity and specificity. Results Data on HC of singleton fetuses at 13-40 gestational weeks were collected. The aver?age age of the pregnant women was 29 years. The proportions of male and female fetuses were 53.1% and 46.9%,respectively,and 97.5% of the fetuses were from Guangdong. The Kappa value and Youden index of the Chinese national reference ranges were 0.86 and 0.97 respectively,higher than those of the other four reference ranges. But the Youden index was on the low side at 23,28,and 40 gestational weeks.In 18 to 28 weeks,the reference ranges of fetal development in white population was doser to the actual detection value. Conclusion s The Chinese national reference ranges of fetal HC are highly consistent with local fetal HC,but not suitable for all gestational weeks. It was recommended to update the reference ranges for Guangdong fetuses.
