We aimed to provide a current birth weight percentile table for singleton and twin pregnancies stratified by gestational week at delivery and sex using data from all live births in Hungary between 2011 and 2015. In addition, we examined temporal trends in average birth weights in singleton and twin pregnancies by sex in five-year periods between 1996 and 2015. We calculated the 5th, 10th, 25th, 50th, 75th, 90th, and 95th centiles of birth weight for each gestational week by sex for singleton and twin pregnancies using compulsory collected obstetrical data (Tauffer Statistics) in Hungary in 2011-2015. Furthermore, we described changes in birth weights by gestational week between 5-year periods from 1996 to 2015. We present birth weight centiles for live births in both tabular and graphical forms using data from 2011 to 2015. In general, live birth weights in gestational weeks 35-41 were lower in the period of 1996-2005 (the lowest in 1996-2000) and were higher in the period of 2006-2010 compared to the reference period of 2011-2015 (e.g., the average male newborn weighed 3249 g at gestational week 38 in 2011-2015, which is 34.3 [SE at 3.0] g less in 1996-2000, 11.5 [2.9] g less in 2001-2005, and 18.1 [2.9] g more in 2006-2010). Similar trends were not observed in birth weights of twin pregnancies in gestational weeks 35-38. Given the observed substantial change in birth weights during the past 20 years, renewal of the commonly used percentile tables is necessary. Birth weights increased from 1996 to 2010, mainly of mature newborns, followed by a stabilization or slight decrease in the later periods. Orv Hetil. 2019; 160(36): 1426-1436.
我们旨在利用2011年至2015年匈牙利所有活产的数据，提供一份按分娩孕周和性别分层的单胎和双胎妊娠的当前出生体重百分位数表。此外，我们研究了1996年至2015年期间单胎和双胎妊娠按性别划分的平均出生体重的时间趋势。我们使用2011 - 2015年匈牙利强制收集的产科数据（陶弗统计），按性别计算了单胎和双胎妊娠每个孕周的出生体重第5、10、25、50、75、90和95百分位数。此外，我们描述了1996年至2015年期间每5年出生体重按孕周的变化。我们使用2011年至2015年的数据以表格和图形形式呈现活产的出生体重百分位数。总体而言，1996 - 2005年期间（1996 - 2000年最低）孕周35 - 41的活产出生体重较低，与2011 - 2015年的参考期相比，2006 - 2010年期间较高（例如，2011 - 2015年孕周38时平均男婴体重为3249克，1996 - 2000年低34.3 [标准误3.0]克，2001 - 2005年低11.5 [2.9]克，2006 - 2010年高18.1 [2.9]克）。在孕周35 - 38的双胎妊娠出生体重中未观察到类似趋势。鉴于过去20年观察到的出生体重的显著变化，更新常用的百分位数表是必要的。出生体重从1996年到2010年增加，主要是成熟新生儿，随后在后期趋于稳定或略有下降。《匈牙利医学周报》。2019年；160(36): 1426 - 1436。
