“…On the other hand, for the aforementioned adverse pregnancy outcomes, evidence has identified several sociodemographic and medical history factors as potential risk factors, which are also associated with ANS dysfunction. These include age (Jandackova et al, 2016;Geovanini et al, 2020), prenatal alcohol consumption (Karpyak et al, 2014;Jurczyk et al, 2019), smoking (Harte et al, 2013;Bodin et al, 2017;Murgia et al, 2019), drug use (Nayak et al, 2020;Lu et al, 2022;Qiu et al, 2023), and body mass index (BMI) (Rodrigues and Quarto, 2018;Triggiani et al, 2019). Due to the associations between the aforementioned risk factors and pregnancy complications and ANS dysfunction, it seems that the ANS may explain the pathway between the risk factors and the pregnancy outcomes, which already indicated in ANS dysfunction (or maybe correctional but not optimal adaptation) in response to the risk factors resulting in pregnancy complications.…”
