The effect of adverse pregnancy outcomes on vascular aging in young women: the Kailuan study.

Adverse pregnancy outcomes (APOs) are at increased future cardiovascular risk and require effective risk mitigation. However, data regarding appropriate postpartum screening for young women with APOs are lacking. We aimed to investigate the association between APOs and vascular aging by the determination of high pulse wave velocity (PWV) in young women. Women who gave birth from 1990 to 2020 and underwent brachial-ankle pulse wave velocity (baPWV) assessments in the postpartum period were recruited. We excluded women with age ≥50 years at the baPWV assessment or missing postpartum health examinations. The history of APOs including hypertensive disorders of pregnancy, gestational diabetes, preterm delivery, and low birth weight were assessed by medical records. High PWV was defined as baPWV above the 90th percentile for different age group. Multivariable Logistic regression was used to evaluate the association of APOs and high PWV. 3193 participants were included in the analysis, including 912 (28.6%) individuals with APOs. The prevalence of high PWV in the non-APO group and the APOs group were 7.19% (164) and 13.9% (127), respectively (P < 0.05). Compared with non-APO group, the OR (95% CI) of APOs group was 1.67 (1.29-2.16). The risks in the 20-29, 30-39, and 40-49 age groups were 2.51 (1.13-5.59), 1.83 (1.30-2.59), and 1.35 (0.82-2.21) (P for trend <0.05). We conclude that APOs are risk factors of vascular aging for young women and the risk decreased with increasing age. BaPWV should be an important indicator for preventive cardiovascular risk management in young women with APOs.
