2131-P: Cardiometabolic Health Indices as Predictors of Hypertensive Disorders of Pregnancy

Introduction and Objective: The rate of hypertensive disorders of pregnancy (HDP) is rising. HDP has been linked to pre-existing cardiometabolic (CM) risk factors, including insulin resistance (IR), BMI, blood lipids, and lactate. Therefore, we sought to understand if an association exists between these markers in early pregnancy and development of HDP in our population. Methods: This cohort was derived from two prospective studies of CM health in pregnant individuals through 22 weeks gestation at a regional academic medical center. Fasting venous blood draws were performed. Differences between groups (those that developed HDP and those that did not) were assessed using T-test and Mann-Whitney U, as appropriate, and binary logistic regression was used to assess which factors predicted subsequent HDP diagnosis. Results: A total of 52 individuals were included in our analysis, with 24 (46.2%) developing HDP (Table). AdipoIR, HOMA-IR, and fasting insulin values were significant predictors of HDP. When controlling for maternal age, gestational age at study visit, and pre-pregnancy BMI, AdipoIR, HOMA-IR, and fasting insulin values remained significant predictors of HDP (p < 0.02). Conclusion: Despite a relatively small sample, markers of IR significantly predicted HDP, even when controlling for maternal age and BMI. Future studies with a larger sample should focus on specific indices of IR and their thresholds for risk assessment of developing HDP. Disclosure R. Purvis: None. N. Zite: None. J. van Nes: None.
