“…This study was conducted in almost the same hospitals as our previous study (study 2013) without the intervention 9. In comparison with data from the 2013 study, pregnant Japanese women without the intervention in this study (control group) exhibited behaviour changes (table 2 and figure 2).…”

“…The rate of seat belt use during pregnancy decreases from that before pregnancy in Japan 9 26. This decrease probably arises from misunderstandings about the safety of seat belt use for a fetus during motor vehicle accidents, despite reports that seat belt use is effective for lowering rates of mortality and morbidity in motor vehicle accidents 15 16.…”

“…Thus, the authors concluded that ‘pregnancy is associated with a substantial risk of a serious motor-vehicle crash during the second trimester, and this risk merits attention for prenatal care’ 8. Using a multicentre questionnaire survey targeting pregnant Japanese women in 2013, we have previously demonstrated that the incidence of motor vehicle accidents during pregnancy was 2.9% 9…”

“…Despite guideline recommendations and clear evidence of the efficacy of seat belt use, the rate of seat belt use by women decreases after confirmation of pregnancy in Japan, probably because of the inappropriate concern that seat belt use might be harmful to the fetus if the pregnant woman is in a motor vehicle accident 9. In a questionnaire survey examining the driving habits of 135 pregnant women in France, between 90% and 100% of pregnant women wore their seat belts irrespective of their stage of pregnancy, although nearly one-third of subjects considered that the seat belt was dangerous for their unborn child 19…”

ObjectiveTo determine whether an educational leaflet had any effect on seat belt use, seat preference and motor vehicle accidents rate during pregnancy in Japan.DesignProspective, non-randomised control trial with a questionnaire survey.SettingEight obstetric hospitals in Sapporo, Japan.Participants2216 pregnant women, of whom 1105 received the leaflet (intervention group) and 1111 did not (control group).InterventionsDistribution of an educational leaflet on seat belt use to women in the intervention group.Primary outcome measuresThe effect of an educational leaflet on seat belt use, each pregnant woman’s seat preference and the women’s rates of motor vehicle accidents rate during their pregnancies. To evaluate the effects, the intervention group’s responses to the questionnaires were compared with those of the control group.ResultsThe proportion of subjects who always used seat belts during pregnancy was significantly higher in the intervention group (91.3%) than in the control group (86.7%; p=0.0005). Among all subjects, the percentage of women who preferred the driver’s seat was lower during pregnancy (27.0%) than before pregnancy (38.7%), and the percentage of women who preferred the rear seat was higher during pregnancy (28.8%) than before pregnancy (21.0%). These two rates did not differ between two groups. Seventy-one women (3.2%) reported experiencing a motor vehicle accident during pregnancy. The motor vehicle accident rate for the intervention group (3.3%) was similar to that for the control group (3.2%).ConclusionsAn educational seat belt leaflet was effective in raising the rate of consistent seat belt use during pregnancy, but it did not decrease the rate of motor vehicle accidents. The wearing of seat belts should be promoted more extensively among pregnant women to decrease rates of pregnancy-related morbidity and mortality from motor vehicle accidents.

PurposeSeatbelt use during pregnancy is important to improve maternal and fetal survival after motor vehicle collisions. However, because the rear seatbelt of a motor vehicle tends to make contact with the neck, even if it is adequately used, some pregnant women sitting in the rear seat opt not to fasten the belt. The purpose of this study is to explore seatbelt–neck contact for pregnant women sitting in the rear seat of a motor vehicle.MethodsWe carried out an anthropometric study. Japanese women who were ≥30 weeks pregnant (n = 12) sat in the left side of the rear seat of a typical mid-size passenger sedan and fastened the seatbelt. Seating posture was investigated by measuring the coordinates of the anthropometric data points of the pregnant women (head, shoulder, hip joint, and knee joint). The belt path was analyzed by measuring the clearance between the belt and the sternum or navel.ResultsAmong the 12 pregnant women at 33.9 week ± 3.3 week gestation, the shoulder belt deviated to the right side and subsequently contacted to the neck in four pregnant women (Contact group). The height of the Contact group was significantly shorter than that of Non-contact group (152.3 cm ± 3.0 cm vs. 159.0 cm ± 3.3 cm, p = 0.008). Regarding the relative position of the seatbelt to the subject's body, the distances from the top of the sternum to the center of the shoulder belt were significantly shorter in Contact group (3.9 cm ± 3.5 cm) than that in the Non-contact group (8.0 cm ± 1.6 cm, p = 0.03). However, no significant difference was found for the distance from the umbilicus to the center of the lap belt.ConclusionOur findings show that because of short height and late term of pregnancy with protrusion of the abdomen, the shoulder belt deviates to the right or left, avoiding the protruded uterus, and subsequently makes contact with the neck. Seatbelt systems for rear seats need to be developed to improve passenger safety, especially for pregnant women.

Seatbelt use and seat preference among pregnant women in Sapporo, Japan, in 2013

Abstract: The careful attitude of pregnant women toward driving safety may be associated with reduced risk of MVA in pregnancy. There is a need for an intensified campaign to promote seatbelt use among pregnant women.
