Percentiles of birth weight by gestational age (GA) are an essential tool for clinical assessment and initiating interventions to reduce health risks. Unfortunately, Poland lacks a reference chart for assessing newborn growth based on the national population. This study aimed to establish a national reference range for birth weight percentiles among newborns from singleton deliveries in Poland. Additionally, we sought to compare these percentile charts with the currently used international standards, INTERGROWTH-21 and WHO.
All singleton live births ( = 3,745,239) reported in Poland between 2010 and 2019 were analyzed. Using the Lambda Mu Sigma (LMS) method, the Generalized Additive Models for Location Scale, and Shape (GAMLSS) package, smoothed percentile charts (3-97) covering GA from 23 to 42 weeks were constructed.
The mean birth weight of boys was 3453 ± 540 g, and this was higher compared with that of girls (3317 ± 509 g). At each gestational age, boys exhibited higher birth weights than girls. The weight range between the 10th and 90th percentiles was 1061 g for boys and 1016 g for girls. Notably, the birth weight of Polish newborns was higher compared to previously published international growth standards.
The reference values for birth weight percentiles established in this study for Polish newborns differ from the global standards and are therefore useful for evaluating the growth of newborns within the national population. These findings hold clinical importance in identifying neonates requiring postbirth monitoring.
按胎龄（GA）划分的出生体重百分位数是临床评估和启动干预措施以降低健康风险的重要工具。不幸的是，波兰缺乏基于全国人口评估新生儿生长情况的参考图表。本研究旨在建立波兰单胎分娩新生儿出生体重百分位数的全国参考范围。此外，我们试图将这些百分位数图表与目前使用的国际标准INTERGROWTH - 21和世界卫生组织（WHO）的标准进行比较。
分析了2010年至2019年波兰报告的所有单胎活产（n = 3,745,239）。使用λμσ（LMS）方法、位置尺度和形状的广义相加模型（GAMLSS）软件包，构建了涵盖23至42周胎龄的平滑百分位数图表（3 - 97）。
男孩的平均出生体重为3453±540克，高于女孩（3317±509克）。在每个胎龄，男孩的出生体重都高于女孩。第10至90百分位数之间的体重范围，男孩为1061克，女孩为1016克。值得注意的是，波兰新生儿的出生体重高于先前公布的国际生长标准。
本研究为波兰新生儿建立的出生体重百分位数参考值与全球标准不同，因此有助于评估全国人口中新生儿的生长情况。这些发现对于识别需要产后监测的新生儿具有临床重要性。
