This study recruited seventeen pregnant women at 30–35 weeks gestation and monitored uterine contractions remotely with a mobile device while recording vehicle acceleration, velocity, and kinematics. Results showed no significant differences in median velocity or acceleration during contractions, and contractions did not appear to predispose to preterm birth.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/motor-vehicle-driving-during-pregnancy-does-not-influence-uterine-contractions/438065/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/motor-vehicle-driving-during-pregnancy-does-not-influence-uterine-contractions/438065.png","ImageObject",300,407,{"name":42,"@type":43},"awa","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-03","2026-09-29",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",15,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What

Uterine contractions were monitored remotely using a mobile delivery monitoring device. Triaxial acceleration of the vehicle, vehicle velocity, and vehicle kinematics were monitored using a driving recorder.  \nResults: Te average number of uterine contractions per 30 min in all participants was 1.0 (range, 0.26–2.0) . When comparing the median vehicle velocity during a uterine contraction with that when there were no contractions, no signifcant diference was found (23 km/hour vs. 31 km/hour, p 􀂈 0.36) . Te prevalence of low velocity (20 km/hour or less) was signifcantly higher, and that of higher velocity (50 km/hour or more) was lower during a uterine contraction than with no contractions (p 􀂈 0.023 and 0.012, respectively) . When comparing resultant vehicle acceleration, no signifcant diferences were found between women with uterine contractions and those with no contractions. Te distributions were similar before and immediately before a uterine contraction and with no contractions.  \nConclusions: Driving a motor vehicle should be considered a normal activity of daily life in pregnant women and seems unlikely to predispose to preterm birth.  \nKeywords: accidents; cardiotocography; fetus; pregnant woman; uterine contraction  \n1. Introduction  \nWorldwide, approximately 1.19 million people die asa result of road trafc crashes. Road trafc injuries are the leading cause of death among children and young adults aged 5–29 years, including pregnant women [1] . Motor vehicle collisions (MVCs) are also a leading cause of fetal death related to maternal trauma. Because these maternal or fetal deaths are preventable with timely management, greater focus on MVCs among pregnant women drivers is needed. Recently, issues related to gender equality have progressed dramatically worldwide. According to a study  \nin a rural area of Japan, approximately 90% of women continue to drive a motor vehicle during their pregnancy [2] . However, because the abdomen of a pregnant woman protrudes to a varying degree depending on the gestational age, some pregnant vehicle drivers have concerns about whether they should continue driving. According toa study using the National Automotive Sampling System/ Crashworthiness Database, abdominal protrusion in pregnant women did not afect the occurrence or severity of abdominal injuries in relatively low-speed frontal collisions [3] . Terefore, safety among pregnant women drivers must be enhanced.  \n2 Obstetrics and Gynecology International  \nSeveral physical o","cbCaip2CRaBDmvw8","https://ap.wps.com/l/cbCaip2CRaBDmvw8","pdf",432855,"English","# Introduction\n# Materials and Methods\n# Results\n# Conclusions","[{\"question\":\"What was the study designed to evaluate?\",\"answer\":\"The study evaluated whether driving a motor vehicle affects physiological changes in pregnant women by examining uterine contractions during driving.\"},{\"question\":\"How were uterine contractions and driving exposure measured?\",\"answer\":\"Uterine contractions were monitored remotely using a mobile delivery monitoring device, while vehicle acceleration, velocity, and kinematics were captured using a driving recorder.\"},{\"question\":\"Did driving influence uterine contraction-related outcomes?\",\"answer\":\"No. The study found no significant differences in resultant vehicle acceleration between women with and without uterine contractions, and the overall findings suggest driving is unlikely to predispose to preterm birth.\"}]","Motor Vehicle Driving During Pregnancy Does Not Influence Uterine Contractions | PDF",1790684063]
