However, to date, no studies have simultaneously explored the relationships between maternal stress, placental expression and methylation of HSD11β2, and fetal cortisol metabolites according to fetal growth. The aim of the present study was to evaluate the association between perceived antenatal maternal stress, the expression and methylation of the placental HSD11β2 gene, fetal cortisol metabolites in amniotic fluid and birth weight.</p><p><strong>Methods: </strong>This nested case-control study, which was part of a large prospective cohort study, was conducted at two maternofetal medicine units in Barcelona, Spain (BCNatal: Hospitals Clinic and Sant Joan de Déu). We enrolled singleton pregnancies and classified neonates as small-for-gestational age (SGA) if their birth weight was below the 10<sup>th</sup> percentile (n = 343) or as appropriate-for-gestational-age (AGA) controls (n = 399). The Perceived Stress Scale (PSS) and the State-Trait Anxiety Inventory (STAI) scores were obtained to assess maternal stress and anxiety levels. We analyzed placental HSD11β2 RNA expression (n = 44 SGA and n = 28 AGA) and DNA methylation levels (n = 89 SGA and n = 34 AGA), and fetal cortisol metabolites and the activity of metabolizing enzymes in amniotic fluid (n = 135 SGA and n = 78 AGA) using liquid chromatography-tandem mass spectrometry.</p><p><strong>Results: </strong>Median maternal perceived stress (PSS, 23 (interquartile range (IQR), 17-28) vs 20 (IQR, 15-26); P < 0.001) and median anxiety state (STAI-state, 19.0 (IQR, 14.0-29.0) vs 16.0 (IQR, 11.0-24.0); P < 0.001) scores were significantly higher in the SGA group compared with the control group. SGA cases showed lower median placental HSD11β2 RNA expression (Δ Ct, 50.5 (IQR, 21.6-106.0) vs 92.7 (IQR, 62.3-118.0); P = 0.013) with similar DNA methylation levels (mean ± SD, 10.7 ± 3.0% vs 11.0 ± 2.8%; P = 0.648) compared with AGA controls. Analysis of amniotic fluid revealed altered cortisol metabolism in SGA fetuses, with increased median 5α-tetrahydrocortisol concentration (SGA, 0.09% (IQR, 0.06-0.15%) vs controls, 0.07% (IQR, 0.05-0.11%); P = 0.020) and activity of its related enzyme (5α-reductase activity in SGA, 0.19% (IQR, 0.14-0.31%) vs controls, 0.17% (IQR, 0.12-0.22%); P = 0.007), together with a decrease in median 6-hydroxycortisol concentration (SGA, 0.09% (IQR, 0.06-0.11%) vs controls, 0.11% (IQR, 0.08-0.12%); P < 0.001) and activity of its related enzyme (CYP3A7 activity in SGA, 0.19% (IQR, 0.11-0.25%) vs controls, 0.24% (IQR, 0.17-0.33%); P < 0.001).</p><p><strong>Conclusions: </strong>SGA pregnancy is associated with high perceived maternal stress and dysregulated fetoplacental cortisol metabolism.

The association of all prenatal candidate variables with HDP and GDM was tested on univariable and multivariable logistic regression analyses. Prediction models were built with generalized linear models using the logit link function and classification and regression tree (XGboost) machine learning algorithm. Performance was assessed with repeated 2-fold cross-validation and the area under the receiver-operating-characteristics curve (AUC) was calculated. A P value < 0.001 was considered statistically significant.</p><p><strong>Results: </strong>A total of 707 198 twin pregnancies were included in the HDP analysis and 723 882 twin pregnancies were included in the GDM analysis. The incidence of HDP and GDM increased significantly from 12.6% and 8.1%, respectively, in 2016 to 16.0% and 10.7%, respectively, in 2021. Factors associated with increased odds of HDP in twin pregnancy were maternal age < 20 years or ≥ 35 years, infertility treatment, prepregnancy diabetes mellitus, non-Hispanic Black race, overweight prepregnancy BMI, prepregnancy obesity and Medicaid as the payment source for delivery (P < 0.001 for all). Obesity Class II and III more than doubled the odds of HDP. Factors associated with increased odds of GDM in twin pregnancy were maternal age ≤ 24 years or ≥ 30 years, infertility treatment, prepregnancy hypertension, non-Hispanic Asian race, maternal birthplace outside the USA and prepregnancy obesity (P < 0.001 for all). Maternal age ≥ 30 years, non-Hispanic Asian race and obesity Class I, II and III more than doubled the odds of GDM. For both HDP and GDM, the performances of the machine learning model and logistic regression model were mostly similar, with negligible differences in the performance domains tested. The mean ± SD AUCs of the final machine learning models for HDP and GDM were 0.620 ± 0.001 and 0.671 ± 0.001, respectively.</p><p><strong>Conclusions: </strong>The incidence of HDP and GDM in twin pregnancies in the USA is increasing. The predictive accuracy of the machine learning models for HDP and GDM in twin pregnancies was similar to that of the logistic regression models. The models for HDP and GDM had modest predictive performance, were well calibrated and did not have poor fit. © 2024 The Author(s).
