Abstract
Objective: This study aimed to evaluate the effect of inter-pregnancy interval (IPI) on the gestational diabetes (GDM) recurrence rate in subsequent pregnancies following an initial pregnancy complicated by GDM.
Study design: A multicenter retrospective cohort study was conducted. The study included women diagnosed with GDM during their index pregnancy who subsequently delivered between 26 and 42 weeks of gestation from 2005 to 2021. The study population was categorized into 8 groups according to their IPIs: up to 3 months, 3-5 months, 6-11 months, 12-17 months, 18-23 months, 24-35 months, 36-47 months, and over 48 months. We examined the recurrence rate of GDM in the different groups compared to the 18-23 months group that was defined as the reference. Statistical analyses included univariate analyses and multiple logistic regression.
Results: Out of 3,532 women that were included in the study, 1776 (50.3%) experienced GDM recurrence in subsequent pregnancy. The recurrence rate was 44.6% for women IPI <6 months, 42.6% for women IPI of 6-11 months, 48.0% for women IPI of 12-17 months, 49.7% for women IPI of 18-23 months, 58.0% for women IPI of 24-47 months and 62.6% for women IPI above 48 months. Multivariable logistic regression revealed that IPIs of 24-47 months and over 48 months were significantly associated with higher recurrence rates as compared to the 18-23 months reference group (adjusted odds ratio [aOR], 95% confidence interval [CI] 1.66 [1.04-2.64] and 3.15 [1.07-9.29], respectively). This analysis also revealed other independent risk factors for GDM recurrence including medication-controlled GDM in the index pregnancy, obesity, maternal age, parity, and gravidity.
Conclusion: Longer IPIs (over 24 months) are associated with an increased risk of GDM recurrence in subsequent pregnancies. Clinicians should consider IPI when managing postpartum care and planning future pregnancies for women with a history of GDM.
期刊介绍：
The American Journal of Perinatology is an international, peer-reviewed, and indexed journal publishing 14 issues a year dealing with original research and topical reviews. It is the definitive forum for specialists in obstetrics, neonatology, perinatology, and maternal/fetal medicine, with emphasis on bridging the different fields.
The focus is primarily on clinical and translational research, clinical and technical advances in diagnosis, monitoring, and treatment as well as evidence-based reviews. Topics of interest include epidemiology, diagnosis, prevention, and management of maternal, fetal, and neonatal diseases. Manuscripts on new technology, NICU set-ups, and nursing topics are published to provide a broad survey of important issues in this field.
All articles undergo rigorous peer review, with web-based submission, expedited turn-around, and availability of electronic publication.
The American Journal of Perinatology is accompanied by AJP Reports - an Open Access journal for case reports in neonatology and maternal/fetal medicine.
