Considerable numbers of pregnant women do not understand the correct way to use seatbelts; thus, they are inappropriately restrained when wearing seatbelts. To improve appropriate seatbelt wearing by pregnant women vehicle passengers, we examined their use by pregnant women drivers and the independent factors influencing appropriate use. We undertook a cross-sectional survey of 1,000 pregnant women in Shiga Prefecture, Japan. Among 774 returned questionnaires, we analysed those of 680 pregnant women who always wore a seatbelt. The mean participant age was 31.4 ± 5.0 years and mean gestational age 26.2 ± 8.2 weeks; 97.7% of subjects always wore a seatbelt; 86.9% wore a seatbelt correctly and 13.1% incorrectly. Multivariate analysis indicated that receiving information about correct seatbelt use (odds ratio, 2.25; P < 0.005) and gestational age (odds ratio, 1.06; P < 0.001) were significant independent factors for correct seatbelt use. Providing information about correct seatbelt use during the early term is required for pregnant women to protect both the mother and fetus.
Pregnant women commonly report various health complaints during pregnancy, the occurrence of which is believed to cause human error. However, no study has examined the relationship between the occurrence of pregnancy complaints and the risk of motor vehicle collisions (MVCs). This study aimed to clarify the relationship between the frequency and severity of common pregnancy complaints and the occurrence of MVCs or near-miss incidents. We conducted a multicenter cross-sectional survey of 1000 pregnant women in Shiga Prefecture, Japan. The event group experiencing MVCs or near-miss incidents during pregnancy comprised 10.8% of respondents. The frequency of compression of the stomach or abdomen, tension and cramps in the lower abdomen, pelvic pain, irritability, depressed mood, distractedness, and hot flashes was significantly higher in the event group. The results of our multivariate logistic regression analysis revealed that tension and cramps in the lower abdomen, distractedness, and irritability were independent contributory factors to such events, with an odds ratio of 2.414, 1.849, and 1.746, respectively. Educating pregnant women to avoid driving when experiencing these symptoms would improve maternal and fetal safety.
Objective: To investigate the actual sleep conditions at four time points from the last trimester of pregnancy to 3 months postpartum, and to examine the relationship between sleep and minor problems affecting sleep. Methods: A cross-sectional survey on the frequency of minor problems, Pittsburgh Sleep Quality Index (PSQI), and observations in a sleep diary was carried out on women at the end of pregnancy, 2 weeks postpartum, 1 month postpartum, and 3 months postpartum. The questionnaires were distributed to 165 participants. Correlation coefficients were obtained for each item and each scale, and the associations were analyzed. Results: The number of valid responses was 127. In the evaluation of sleep, sleep duration was the shortest and sleep quality was the lowest in the first month after delivery based on the PSQI score. In the correlation between “psychiatric symptoms” and sleep, women with anxiety and nervousness at the end of pregnancy were associated with poorer sleep quality. At all time-points, there was a significant association between “psychiatric symptoms” and poor sleep quality. Conclusion: An association exists between “psychiatric symptoms” and poor sleep quality in women from the last trimester of pregnancy to 3 months postpartum.
