The objective of this study was to assess maternal gestational outcomes and offspring growth trajectories following prepregnancy metabolic and bariatric surgery (MBS) compared with non-MBS controls.
Single-center deliveries between January 2020 and March 2023 with prepregnancy Roux-en-Y gastric bypass (herein referred to as "bypass"), sleeve gastrectomy (herein referred to as "sleeve"), and non-MBS controls were included. Offspring growth trajectories were compared with the World Health Organization child growth standards. Linear mixed models assessed MBS-bypass and MBS-sleeve offspring weight, length, and BMI trajectories with a prepregnancy BMI 27 to 37 kg/m and propensity score-matched controls.
The study included 440 participants with prepregnancy MBS (MBS-bypass, 185; MBS-sleeve, 225; 76% Hispanic/Latino) and 13,434 non-MBS controls. Gestational weight gain and gestational diabetes mellitus were similar, whereas hypertensive disorders of pregnancy were more common after MBS. The post-MBS offspring had lower birth weight but higher weight gain at 24 months (sleeve, +1.4 kg [95% CI: 1.0-1.9]; bypass, +0.5-0.7 kg [95% CI: 0.0-1.2]) compared with non-MBS groups. Male children had higher weight gain than females. The post-MBS-sleeve but not the post-MBS-bypass offspring had higher BMI z scores.
The higher early-life weight gain and sex differences in the post-MBS-sleeve group compared with the post-MBS-bypass group provide a window toward elucidating pathways to mitigate intergenerational metabolic risk transfer.
本研究旨在评估与非代谢和减重手术(MBS)对照组相比,孕前 MBS 后母婴的妊娠结局和后代生长轨迹。
纳入 2020 年 1 月至 2023 年 3 月间单中心分娩的孕前 Roux-en-Y 胃旁路术(以下简称“旁路”)、袖状胃切除术(以下简称“袖套”)和非 MBS 对照组患者。后代生长轨迹与世界卫生组织儿童生长标准进行比较。线性混合模型评估了孕前 BMI 为 27 至 37kg/m 且具有倾向评分匹配对照的 MBS-旁路和 MBS-袖套后代体重、身长和 BMI 轨迹。
本研究共纳入 440 名孕前 MBS 患者(MBS-旁路 185 例,MBS-袖套 225 例,76%为西班牙裔/拉丁裔)和 13434 名非 MBS 对照组。两组的妊娠体重增加和妊娠糖尿病相似,但 MBS 后妊娠高血压疾病更为常见。与非 MBS 组相比,MBS 后后代出生体重较低,但 24 个月时体重增加更多(袖套:+1.4kg[95%CI:1.0-1.9];旁路:+0.5-0.7kg[95%CI:0.0-1.2])。男性儿童体重增加高于女性。MBS-袖套后而非 MBS-旁路后后代的 BMI z 评分更高。
与 MBS-旁路后相比,MBS-袖套后后代更早的体重增长更高,且存在性别差异,为阐明减轻代际代谢风险传递的途径提供了一个窗口。
