Abstract

Objective: To categorize growth and correlate growth categories with morbidities in infants born before 32 weeks of gestation.

Study design: This retrospective study categorized weight growth by correlating mean growth velocity (GV) with growth trajectory z-score changes ( $Δ G T Z$ ), as measured using 2023 Postnatal Growth Charts for Preterm Infants. The associations between weight categories and morbidities were assessed.

Results: Weight gain of infants without morbidities was categorized into three groups based on correlating $Δ G T Z$ with mean GV: slower ( $Δ G T Z$ < -0.1), in-parallel ( $Δ G T Z$ -0.1 to 0.3), and faster ( $Δ G T Z$ > 0.3). The proportions of infants with and without morbidities in these categories were evaluated across two distinct cohorts, revealing similar patterns. Both slower and faster growth were associated with bronchopulmonary dysplasia, while only slower growth was associated with retinopathy of prematurity.

Conclusion: Using the 2023 Postnatal Growth Charts for Preterm Infants, this study presents an alternative method for weight growth categorization.

使用2023年早产儿产后生长图对妊娠32周前出生婴儿的体重增长进行分类。

目的：对妊娠32周前出生的婴儿进行生长分类，并将生长分类与发病率联系起来。研究设计：这项回顾性研究通过将平均生长速度（GV）与生长轨迹Z -score变化（Δ G - T - Z）相关联来对体重增长进行分类，该研究使用2023年早产儿出生后生长图进行测量。评估了体重类别与发病率之间的关系。结果：根据Δ gtz与平均GV的相关性，将无发病婴儿体重增加分为三组：较慢组（Δ gtz Δ gtz -0.1 ~ 0.3）和较快组（Δ gtz > 0.3）。在两个不同的队列中评估了这些类别中有和没有发病率的婴儿的比例，揭示了相似的模式。较慢和较快的生长均与支气管肺发育不良有关，而只有较慢的生长与早产儿视网膜病变有关。结论：利用2023年早产儿出生后生长图，本研究提出了一种体重增长分类的替代方法。
