Abstract

Background: Limited studies have investigated the influence of body mass index (BMI) trajectories on lung function covering the entire growth period.

Methods: We conducted a prospective study utilizing data from the Swedish BAMSE birth cohort. Latent class mixture modelling was employed to examine the diversity in BMI z-scores from birth to 24 years of age. Participants with four or more BMI z-scores were included (n=3204, 78·4%). Pre-bronchodilator (BD) spirometry was tested at 8, 16, and 24 years, while post-BD spirometry, multiple-breath nitrogen washout (for lung clearance index, LCI), and urinary metabolomics data were assessed at 24 years.

Results: Six distinct BMI development groups were identified. Compared to the stable normal BMI group, the accelerated increasing BMI group exhibited reduced pre- and post-BD FEV1/FVC ratio z scores (β=-0·26, 95% CI=[-0·44, -0·08], and -0·22, [ -0·39, -0·05], respectively), along with elevated LCI (0·30, [0·22, 0·42]) at 24 years. The persistent high BMI group demonstrated lower FEV1, and FVC z scores growth between 16 and 24 years (-0.24, [-0.42, -0.05], and -0.27, [-0.45, -0.01], respectively), and elevated LCI (0·20, [0·03, 0·39]) at 24 years. However, those impairments were not observed in the accelerated resolving BMI group. Conversely, the persistent low BMI group displayed persistently decreased FEV1, and FVC from 8 to 24 years, as well as decreased lung function growth. Additionally, histidine-related metabolites were associated with pre- and post-BD FEV1 (hypergeometric FDR=0.008 and <0.001, respectively).

Conclusions: Early interventions aiming for normal BMI during childhood may contribute to improved lung health later in life.

从出生到成年早期的体重指数轨迹与肺功能发育。
背景:对身体质量指数(BMI)轨迹对整个生长期肺功能影响的研究有限:我们利用瑞典 BAMSE 出生队列的数据进行了一项前瞻性研究。方法:我们利用瑞典 BAMSE 出生队列的数据进行了前瞻性研究,采用了潜类混合模型来研究从出生到 24 岁期间体重指数 z 值的多样性。研究纳入了具有四个或更多 BMI z 值的参与者(n=3204,78-4%)。8、16和24岁时测试了支气管扩张剂(BD)前肺活量,24岁时评估了BD后肺活量、多次呼吸氮冲洗(用于肺清除指数LCI)和尿液代谢组学数据:结果:确定了六个不同的 BMI 发展组。与稳定的正常 BMI 组相比,BMI 加速增长组在 24 岁时表现出 BD 前和 BD 后 FEV1/FVC 比值 z 评分降低(β=-0-26,95% CI=[-0-44,-0-08]和-0-22,[ -0-39,-0-05]),LCI 升高(0-30,[0-22,0-42])。持续高体重指数组在16至24年间的FEV1和FVC z得分增长较低(分别为-0.24,[-0.42,-0.05]和-0.27,[-0.45,-0.01]),24岁时的LCI升高(0-20,[0-03,0-39])。然而,在 BMI 加速消退组中没有观察到这些损伤。相反,持续低体重指数组在 8 至 24 年间显示出持续的 FEV1 和 FVC 下降,以及肺功能增长下降。此外,组氨酸相关代谢物与BD前后的FEV1相关(超几何FDR=0.008,结论:以儿童期正常体重指数为目标的早期干预可能有助于改善日后的肺部健康。

期刊介绍: The European Respiratory Journal (ERJ) is the flagship journal of the European Respiratory Society. It has a current impact factor of 24.9. The journal covers various aspects of adult and paediatric respiratory medicine, including cell biology, epidemiology, immunology, oncology, pathophysiology, imaging, occupational medicine, intensive care, sleep medicine, and thoracic surgery. In addition to original research material, the ERJ publishes editorial commentaries, reviews, short research letters, and correspondence to the editor. The articles are published continuously and collected into 12 monthly issues in two volumes per year.
