Factors related to indecisive attitudes toward non-invasive prenatal testing among women of reproductive age in Japan.

AIM: This study aimed to investigate the factors related to indecisive attitudes toward noninvasive prenatal testing (NIPT) among nonpregnant women of reproductive age. METHODS: We conducted an online survey involving nonpregnant Japanese women aged 20-49 years. The questionnaires consisted of a hypothetical question about whether they would decide to undergo NIPT if they were to become pregnant, and responses with "unsure" were defined as indecisive attitudes. RESULTS: Of 1250 participants, 412 (33%) held indecisive attitudes on whether to undergo NIPT. Multivariable logistic regression analysis demonstrated indecisive attitudes were related to a low level of knowledge about prenatal testing (adjusted odds ratio [AOR] 3.89) and preferences for family-driven decisions (AOR 1.44) instead of provider-driven. CONCLUSION: Even though the NIPT is widespread, many nonpregnant women of reproductive age are unable to decide whether to undergo the NIPT or not. Hence, indecisive women toward NIPT require adequate information and communication about future NIPT among their families prior to conception. Therefore, preconception support of providing adequate information about testing and facilitating communication regarding future NIPT among women and their family members may help indecisive women make autonomous decisions on NIPT.

Depression and diet-related distress among Japanese women with gestational diabetes mellitus.

Although the association between gestational diabetes mellitus (GDM) and maternal postpartum depression has been reported, the association between these two factors during pregnancy has not been sufficiently examined. We compared pregnant women with and without GDM to clarify the association and examined factors related to depression in pregnant women with GDM. Questionnaires were administered longitudinally to pregnant Japanese women in the third trimester and at 2 and 4 weeks postpartum. One hundred and five and 108 pregnant women with and without GDM, respectively, were included in the study. Of the 105 women with GDM, 20 (19.0%) reported being depressed during pregnancy, which was significantly higher than that among those without GDM (9.3%). Binomial logistic regression analysis revealed that depression was significantly positively associated with diet-related distress and negatively associated with social support among women with GDM. Diet-related distress and social support are important factors in managing depression in pregnant women with GDM.

Traditional menstruation practices among Nepalese women living in Japan.

BACKGROUND: Traditional menstruation practices in Nepal (Chhaupadi in Nepalese) lack scientific support and undermine women's health. This study aimed to understand the changes in the traditional menstruation practices due to migration from Nepal to Japan. METHODS: This study included 104 Nepalese women of reproductive age living in an urban area of western Japan. Participants were recruited using snowball sampling, and the method of data collection was a questionnaire survey. To examine how Nepalese women adapt traditional menstruation practices to their living environment, we compared how women followed frequently 17 traditional practices when they lived in Nepal and later in Japan. We examined the relationships among behavioural changes in traditional practices, education level, and caste. RESULTS: The frequency of 14 of the 17 traditional practices decreased after the women moved to Japan. Among women who reduced the frequency of traditional practices after moving from Nepal to Japan, the reduction was not associated with educational level or caste of the participants. CONCLUSIONS: This study suggests that the attitudes towards the traditional menstruation practices change in response to living circumstances. Future studies should focus on determining living environment factors related to behavioural changes in traditional practices.

Development of a scale to evaluate negative menstrual attitudes among Nepalese women.

BACKGROUND: Menstrual attitudes include negative and positive perceptions of menstruation and are associated with reproductive health, underscoring the importance of its evaluation in women. Given that social and cultural factors affect menstrual attitudes, developing evaluation methods specific to distinct societal cultures is necessary. METHODS: We developed a scale based on the menstrual attitude questionnaire, which is the most widely used measure of menstrual attitudes, to evaluate negative menstrual attitudes among Nepalese women in consideration of Nepalese cultural backgrounds and literacy. In total, 352 Nepalese women aged 20-45 years living in urban or suburban areas in Nepal were enrolled in the study. Participants were randomly divided into two groups using the permuted block method. Using the prototype, Group 1 (n = 176) was evaluated with an exploratory factor analysis to develop a reliable scale, and Group 2 (n = 176) was evaluated with a confirmatory factor analysis to confirm the structure of negative menstrual attitudes. Further, we preliminarily examined the relationship of negative menstrual attitudes with the frequency of traditional menstrual practices and intensity of menstrual pain, which are significant reproductive health issues in Nepal, in Group 2. RESULTS: We developed a 15-item, 3-factor scale to evaluate negative menstrual attitudes among Nepalese women using exploratory factor analysis. The first, second, and third factors were "Natural event" (α = 0.82), "Debilitating event" (α = 0.76), and "Bothersome event" (α = 0.69), respectively. Confirmatory factor analysis revealed that negative menstrual attitudes comprised a 3-factor structure. Participants who performed three traditional menstrual practices ("stay in their own house", "go to public spaces", and "contact with others generally") demonstrated significantly higher scores for negative menstrual attitudes than did non-performers. Negative menstrual attitudes were positively correlated with the intensity of menstrual pain (r = 0.558). CONCLUSIONS: This study is the first to evaluate menstrual attitudes and analyse its factor structure among Nepalese women. In the future, the relationship between accurately evaluated negative menstrual attitudes and reproductive health issues should be examined more comprehensively.

For sexually mature women, menstruation may be considered burdensome, but its absence may also be a source of concern. Perceptions regarding menstruation are collectively referred to as menstrual attitudes. Previous studies have reported that negative menstrual attitudes are associated with various reproductive health issues in women and vary according to social and cultural backgrounds. To adequately evaluate negative menstrual attitudes among Nepalese women (20­45 years old), we developed a 15-item scale that considers their cultural background and literacy. We observed that attitudes toward menstruation among Nepalese women consisted of three emotions: one positive emotion, including "menstruation is a natural phenomenon", and two negative emotions, including "menstruation is debilitating" and "menstruation is bothersome". In several developing countries, menstruating women are considered unclean, and various restrictions are imposed on women during menstruation (traditional menstrual practices). Nepalese women with strong negative menstrual attitudes, as assessed by our scale, engaged in several traditional menstrual practices with higher frequency. We also observed that women with more negative menstrual attitudes presented with more severe menstrual pain. Our scale was developed to be compatible with the values and literacy of Nepalese women and was easy to answer. We believe that reducing negative emotions toward menstruation will contribute to reducing the frequency of traditional menstrual practices and menstrual pain, thereby facilitating school attendance and entry into the workforce among women in Nepal.

Effects of past environmental tobacco smoke exposure on the menstrual cycle and menstrual phase-related symptoms: A cross-sectional study.

AIM: This study examined the effects of current and past environmental tobacco smoke exposure on the menstrual cycle and menstrual phase-related symptoms in nonsmoking Japanese women of child-bearing age. METHODS: Of 5000 women who agreed to participate, 3935 were analyzed (932 smokers, 2326 nonsmokers, and 677 past smokers). Nonsmokers were divided into three groups based on smoking status and environmental tobacco smoke exposure: nonsmokers without exposure (n = 352), nonsmokers with past exposure (n = 1196) and nonsmokers with current exposure (n = 778). Participants completed a questionnaire on background characteristics, environmental tobacco smoke exposure (location and relationship to smokers), abnormal menstrual cycle, days of menstrual cycle and menstrual cycle-related symptoms experienced in the past 3 months (assessed by the Menstrual Distress Questionnaire). RESULTS: Mean age was 29.7 ± 7.0 (20-44) years. Compared with nonsmokers without environmental tobacco smoke exposure, current smokers had the highest risk of an abnormal menstrual cycle (adjusted odds ratio [OR], 1.74 [1.194-2.545]), followed by nonsmokers with past exposure (adjusted OR, 1.70 [1.171-2.464]), past smokers (adjusted OR, 1.60 [1.081-2.366]) and nonsmokers with current environmental tobacco smoke exposure (adjusted OR, 1.49 [0.901-1.212]). Irrespective of environmental tobacco smoke exposure, current smokers reported significantly more severe premenstrual and menstrual symptoms than nonsmokers, and nonsmokers with past environmental tobacco smoke exposure had significantly more severe premenstrual and menstrual symptoms than nonsmokers without environmental tobacco smoke exposure. CONCLUSION: Past environmental tobacco smoke exposure, especially during childhood or adolescence, might harm women's reproductive health when they reach reproductive age.

Regret over the delay in childbearing decision negatively associates with life satisfaction among Japanese women and men seeking fertility treatment: a cross-sectional study.

BACKGROUND: Currently, in developed countries, increasing numbers of women and men are delaying childbearing but begin seeking fertility treatment later in life. Some women undergoing infertility treatment develop negative feelings such as depression associated with low life satisfaction and regret over the delay in childbearing. We therefore examine the association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors among Japanese women and men seeking fertility treatment. METHODS: This cross-sectional study included 253 women and 196 men referred to fertility facilities in Japan from July to December 2018. Participants completed a questionnaire on life satisfaction, regret over the delay in childbearing decision, infertility-related factors and sociodemographic characteristics. Life satisfaction was measured using the Satisfaction with Life Scale (SWLS), and the degree of regret over delay in childbearing decision was measured on a 7-point Likert scale. Multiple linear regressions, conducted separately by sex, were used to analyze the association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors. RESULTS: Of the 253 women and 196 men, 102 (40.3%) women and 43 (21.9%) men answered "strongly agree" regarding their regret over the delay in childbearing decision. Among women, life satisfaction was negatively associated with regret (ß = - 0.155, 95% CI [- 0.938, - 0.093], p = 0.017), use of assisted reproduction technology (ART) (ß = - 0.135, 95% CI [- 2.977, - 0.020], p = 0.047). In contrast, previous live birth was positively associated with life satisfaction (ß = 0.134, 95% CI [0.122, 3.739], p = 0.037). In men, we found no significant association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors. CONCLUSIONS: Regret over the delay in childbearing decision is negatively associated with life satisfaction among Japanese women seeking fertility treatment. It may be important for women to make better informed decision regarding the timing of childbearing to not regret later in life. Health professionals should address regret over the delay in childbearing decision during fertility treatment and explore ways to spread information on fertility awareness.

Parental factors predicting unnecessary ambulance use for their child with acute illness: A cross-sectional study.

AIMS: To examine characteristics of parents of children with acute, albeit mild, illnesses who used ambulance transport unnecessarily. DESIGN: A cross-sectional study. METHODS: From 2016 - 2017, we recruited parents who visited the emergency room of a Japanese paediatric hospital and whose children were discharged without hospitalization. Participants whose children arrived by ambulance were classified as using ambulance services unnecessarily. Participants answered a questionnaire consisting of parents' characteristics, including health literacy scales and the Parents' Uncertainty regarding their Children with Acute Illness Scale. We conducted a receiver operating characteristic analysis to convert the Parents' Uncertainty regarding their Children with Acute Illness Scale results to binary scores. We analysed questionnaire responses using logistic regression analysis. RESULTS: Analysed data were from 171 participants. The cut-off score was 59 for the Parents' Uncertainty regarding their Children with Acute Illness Scale. Results of the logistic regression indicated that parents who did not use resources to obtain information regarding their child's illness, had low health literacy, were observing presenting symptoms for the first time in their child, or had high uncertainty, were significantly more likely to unnecessarily use ambulances. CONCLUSION: Publicizing available resources regarding child health information, social healthcare activities to raise parents' health literacy and providing explanations in accordance with parents' uncertainty, especially when confronting new symptoms in their child, might reduce unnecessary ambulance use. IMPACT: Of patients transported to hospitals by ambulance, the rate of paediatric parents with mild conditions has been found to be high. The study findings could contribute to the appropriateness of using ambulances and have implications for policymakers and healthcare providers, particularly in the Japanese paediatric emergency system. In particular, parental uncertainty, one of four significant characteristics, could be resolved in clinical settings. Generalization for global health services requires further research.

Assessing body dissatisfaction in Japanese women during the second trimester of pregnancy using a new figure rating scale.

During pregnancy, women re-evaluate their body image based on their increasing body weight. They are usually concerned about their body size, which leads to body dissatisfaction. In this study, we investigated body dissatisfaction among Japanese women during the second trimester, when they are recommended to gain adequate weight. A cross-sectional survey of body dissatisfaction among pregnant women was conducted using a new figure rating scale corresponding to body mass index with real-life photographs of women in their sixth month of gestation. Pregnant Japanese women expressed body dissatisfaction and preferred to be thinner by 1.6 kg/m2 of their body mass index. They perceived their body size as larger than their real size, and those with a higher body mass index had more body dissatisfaction, although they were of normal weight or underweight. The results indicated that the new figure rating scale could be a useful tool to identify pregnant women with higher body dissatisfaction during the second trimester, providing an opportunity to discuss adequate gestational weight gain with pregnant women.

Pain in labor assessed from two discomfort aspects: Physical pain intensity and psychological stress state.

AIM: To assess two discomfort aspects of pain in labor, physical pain intensity and psychological stress state, we analyzed the association between the two parameters. METHODS: Twenty-nine pregnant Japanese women with a singleton in 37-40 weeks of gestation were analyzed. Physical pain intensity was examined by the Numeric Rating Scale (NRS). Psychological stress state was measured by chromogranin A (CgA) in saliva. Data were collected thrice during labor (at 4-6 cm and 10 cm of cervical dilatation and immediately after delivery) and were accumulated from 4-6 cm and 10 cm of cervical dilatation. The study was approved by the Ethics Committees of Osaka University and Tokyo Women's Medical University. RESULTS: The median NRS score (10, IQR = 10-18) and the median CgA in saliva (8.0, IQR = 4.3-12.0) pmol/mg at 10 cm of cervical dilatation were significantly higher than those at the other two time points (P < 0.05). Although there were no correlations between NRS scores and concentrations of CgA in saliva at the three time points, there was a significant correlation between accumulated NRS and accumulated CgA in saliva (r = 0.68, P = 0.000). There was a significant difference in the accumulated NRS scores (P = 0.005) but not in the accumulated concentrations of CgA between primiparae and multiparae. CONCLUSION: Women in labor perceived severe pain and psychological stress with similar patterns during labor. However, these parameters were independent and need to be measured to evaluate these two discomfort aspects.

Impact assessment of a maternal health project in a megacity, Nigeria: toward a future with more demand for maternal health services.

To improve the quantity and quality of maternal health services in Lagos State, Nigeria having a maternal mortality ratio of 555 per 100 000 live births, a four-year project was implemented since February 2010. The major activity of the project was training for both the service supply and demand sides. This study aimed to examine the impact of the project on coverages and quality of the services in target areas, and guide statewide policies. The Cochran-Armitage test for trend was applied to understand trends in the service coverages during 2009-2013. The same test was performed to analyse trends in the proportions of perineal conditions (i.e. intact or tear) and to evaluate variations in midwives' snkill during 2011-2013. The paired t-test was used to analyse changes in midwives' knowledge. The project interventions contributed to a significant increase in the overall service coverages, including improvements in midwifery knowledge and possibly in their skills. However, the service coverage was still limited as of the termination of the project. To instal the interventions and maximise the effect of them state-wide, it is recommended to undertake five tasks: (i) establishment of public primary health centres offering 24-h maternal health services; (ii) redeployment and recruitment of public health personnel; (iii) expansion of midwifery trainings and continuous education by the local trainers; (iv) review of grass-roots level activities; and (v) scrutiny of barriers to maternal health services.

Paternal postnatal depression in Japan: an investigation of correlated factors including relationship with a partner.

BACKGROUND: A negative effect of paternal depression on child development has been revealed in several previous studies. The aims of this study were to examine the prevalence and relevant factors associated with paternal postnatal depression at four months postpartum, including age, part-time work or unemployment, experience of visiting a medical institution due to a mental health problem, economic anxiety, unexpected pregnancy, pregnancy with infertility treatment, first child, partner's depression, and lower marital relationship satisfaction. METHODS: We distributed 2032 self-report questionnaires to couples (one mother and one father) with a 4-month old infant between January and April 2013. Data from 807 couples (39.7 %) were analyzed. Depressive symptoms were measured with the Edinburgh Postnatal Depression Scale (EPDS). In order to clarify the factors related with paternal depression, a logistic regression analysis was conducted. RESULTS: One hundred and ten fathers (13.6 %) and 83 mothers (10.3 %) were depressed. According to the logistic regression analysis, paternal depression was positively associated with partner's depression (adjusted odds ratio (AOR) 1.91, 95 % confidence interval (CI) 1.05-3.47), and negatively with marital relationship satisfaction (AOR 0.83, 95 % CI 0.77-0.89). History of infertility treatment (AOR 2.37, 95 % CI 1.32-4.24), experience of visiting a medical institution due to a mental health problem (AOR 4.56, 95 % CI 2.06-10.08), and economic anxiety (AOR 2.15, 95 % CI 1.34-3.45) were also correlated with paternal depression. CONCLUSIONS: This study showed that the prevalence of paternal depression at four months after childbirth was 13.6 % in Japan. The presence of partner's depression and low marital relationship satisfaction were significantly correlated with paternal postpartum depression, suggesting that health professionals need to pay attention to the mental status of both fathers and mothers, and to their relationship.

Childbirth expense support and small-for-gestational-age infants in Japan.

BACKGROUND: Poor nutritional status during the fetal period could cause perinatal and lifelong health disadvantages in neonates. The aim of this study was to investigate the background of pregnant women receiving childbirth expense support (CES), pregnancy outcome, and neonatal anthropometric data. METHODS: A retrospective cohort study was conducted using 823 antenatal and delivery records in a perinatal center located in one of the poorest areas in Japan. Neonates who were small for gestational age (SGA) were compared between the CES and the non-CES groups. RESULTS: The incidences of low birthweight (LBW) and SGA were significantly higher in the group receiving CES (14.6% and 14.6%, respectively). The adjusted OR of CES was 2.78 (95%CI: 1.32-5.87) and the adjusted OR of maternal smoking was 5.03 (95%CI: 2.74-9.21), indicating that CES and maternal smoking were directly associated with SGA. CONCLUSIONS: CES recipients had a higher prevalence of SGA infants. CES was independently associated with SGA. Previous studies have shown that smoking is a major risk factor for SGA. Further studies are needed to identify risk factors of SGA specific to CES recipients.

Reduction of tobacco smoke exposure for pregnant passive smokers using feedback of urinary cotinine test results.

AIMS: Our objective was to evaluate the level of pregnant women's exposure to tobacco smoke by urinary cotinine testing at prenatal examinations, and to examine the effects of disclosing the results of urinary cotinine tests to pregnant women and their families on their smoking activities. METHODS: A prospective cohort study was conducted, enrolling 420 pregnant women who attended prenatal examinations at five private clinics in Japan. Urinary cotinine testing and a questionnaire survey regarding smoking status were conducted in early, middle, and late pregnancy. Urinary cotinine values were measured semiquantitatively using NicCheck I test strips. The results of each urinary cotinine test were handed to the pregnant woman and shared with her family. RESULTS: The percentages of urinary cotinine-positive subjects in middle and late pregnancy were significantly decreased compared with early pregnancy (P<0.001 each). Among the active smokers, there were no significant differences in the urinary cotinine-positive rates and the numbers of cigarettes among the three stages. In contrast, the urinary cotinine-positive rates in the passive smokers in late pregnancy were significantly lower than in early pregnancy (P=0.045) and those in non-smokers in middle and late pregnancy were also lower than in early pregnancy (P=0.001, P<0.001). The numbers of cigarettes smoked by persons close to the passive smokers in middle and late pregnancy were significantly lower than in early pregnancy (P<0.001). CONCLUSIONS: The feedback of the urinary cotinine test results at prenatal examinations decreased the level of exposure of pregnant passive smokers and non-smokers to tobacco smoke.

Relationship in Japan between maternal grandmothers' perinatal support and their self-esteem.

This study investigated the influence on their mental well-being of the perinatal support given by Japanese grandmothers. The Rosenberg self-esteem and the Center for Epidemiologic Studies Depression (CES-D) scales were used to assess grandmothers' mental well-being before and after their daughters' childbirth. Of 198 grandmothers, 176 (88.9%) supported their daughters and three patterns of perinatal support were observed: grandmothers' support at the grandparents' house before childbirth (n = 95) (Satogaeri bunben; Japanese traditional perinatal support), grandmothers' support at the grandparents' house after childbirth (n = 53); and grandmothers' support at the daughters' house (n = 28). Those who supported their daughters at the grandparents' house before childbirth - especially the middle-aged (less than 60 years old) - showed significantly lower scores of self-esteem. Scores of CES-D did not significantly change before and after childbirth in either subgroup of grandmothers. It was concluded that grandmothers play an important role in supporting their daughters, and Satogaeri bunben is a typical event in modern Japan. However, Satogaeri bunben is a burden for middle-aged grandmothers, and we need to support them.

Longitudinal analysis of body dissatisfaction: the desire to be thinner among women in Japan during low-risk pregnancies.

Body dissatisfaction during pregnancy can significantly impact maternal and child health. Therefore, this longitudinal study investigated changes in body dissatisfaction using two figure rating scales developed from photographic digital data of Japanese pregnant women during the sixth and tenth months of pregnancy. Study participants were recruited at their sixth month prenatal visit at a primary maternity clinic in Japan from October 2014 to March 2015. Body dissatisfaction was estimated based on the perceived and ideal body sizes of 135 pregnant women, expressed as body mass index. Data were collected using self-administered questionnaires. The study found that body dissatisfaction in the tenth month was significantly higher than that in the sixth month. Among the participants, 75 (55.6%) and 79 (58.5%) experienced body dissatisfaction, desiring to be thinner (where perceived body size exceeded ideal body size) during the sixth and tenth months of pregnancy, respectively. Pregnant women who had body dissatisfaction and a desire to be thinner in the sixth month tended to experience an increase in body dissatisfaction by the tenth month compared to those without body dissatisfaction in the sixth month. During the sixth and tenth months, women with body dissatisfaction showed significantly larger perceived body sizes than those without body dissatisfaction. These results indicated that the use of a figure rating scale at the sixth month of pregnancy may help identify women with body dissatisfaction; moreover, perceived body size might be a key factor in preventing an increase in body dissatisfaction from the second to third trimesters.

Association of menstrual phase with smoking behavior, mood and menstrual phase-associated symptoms among young Japanese women smokers.

BACKGROUND: Previous studies of the relationship between the menstrual phases and smoking behavior have been problematic, so the association of menstrual phases with smoking behavior and correlations among smoking, psychological and physical conditions in each phase of the menstrual cycle are unclear. METHODS: To accurately examine the association between menstrual phases and the amount of smoking (number of cigarettes smoked and breath CO concentration), craving of smoking on visual analogue scale (VAS), depression in the Center for Epidemiologic Studies Depression (CES-D) Scale, and menstrual phase-associated symptoms in the Menstrual Distress Questionnaire (MDQ), we improved various methodological issues, specifically, 1) Ovulation was confirmed by measuring the basal body temperature and identifying a urinary luteinizing hormone (LH) surge in two cycles; 2) The menstrual, follicular, and luteal phases were clearly defined for subjects with different menstrual cycles; 3) The breath CO concentration was measured every day. A notice was posted on public bulletin boards to recruit research subjects and twenty-nine young Japanese women smokers aged 19 to 25 years old were analyzed. RESULTS: The number of cigarettes smoked was greater and the CO concentration was higher in the luteal phase than in the follicular phase. The levels of craving for smoking (VAS), depressiveness (CES-D), and menstrual phase-associated symptoms (MDQ) in the menstrual and luteal phases were higher than those in the follicular phase. The mean score for CES-D was 16 points (the cut-off value in screening for depression) or higher in the menstrual (16.9 ± 8.2) and luteal phases (17.2 ± 8.4).The number of cigarettes smoked and CO concentration were significantly correlated with the levels of craving for smoking, depressiveness, and menstrual phase-associated symptoms in all phases except for MDQ scores in follicular phase. The amount of smoking in the luteal phase was most strongly correlated with these symptoms. CONCLUSIONS: In the menstrual and luteal phases, young Japanese women smokers increased their amount of smoking and suffered from greater craving for smoking, depressiveness and menstrual phase-associated symptoms. The amount of smoking was correlated with these symptoms, but their cause-effect relationship has not been determined yet.

Preconception education program for non-invasive prenatal testing focused on interest in genetics among female university students in Japan: a quasi-experimental study comparing pre-intervention, post-intervention, and three-month follow-up results.

BACKGROUND: Non-invasive prenatal testing (NIPT) is offered as a reproductive choice in many countries. However, pregnant women, particularly those who are primipara or lack knowledge of prenatal testing, experience difficulties understanding adequate information and making decisions on NIPT. This study developed a preconception education program about NIPT, focusing on interest in genetics, and aimed to clarify the effectiveness of the program to help women make decisions on future NIPT. METHODS: This was a one-group, quasi-experimental, pre-post-test study. The study population was female undergraduate students in Japan who participated in the education program. This program included two games and was based on the Attention, Relevance, Confidence, and Satisfaction (ARCS) model, which is an instructional design that stimulates learning interest and motivation. The data of 73 pre-pregnant women who completed all three questionnaires-before, immediately after, and three months after the intervention-were analyzed to clarify the time effects. Moreover, all variables were analyzed using logistic regression analysis to investigate factors related to decisional conflict. RESULTS: Interest in genetics, knowledge of genetics and prenatal testing, and indecisive attitudes toward NIPT significantly improved immediately after the intervention, and consequently, these changes and reduction of decisional conflict were maintained at three months. Moreover, low decisional conflict at follow-up was significantly associated with a high interest in genetics (adjusted odds ratio, 3.42). CONCLUSIONS: These findings provide preliminary evidence that this preconception education program, which focused on facilitating interest in genetics, assists pre-pregnant women to reduce decisional conflict about future NIPT. TRIAL REGISTRATION: The trial was registered at the UMIN-CTR registry (January 16, 2023), registration number UMIN000050047.

Assessing Engagement With Patient-Generated Health Data Recording and Its Impact on Health Behavior Changes in Multicomponent Interventions: Supplementary Analysis.

BACKGROUND: The use and sharing of patient-generated health data (PGHD) by clinicians or researchers is expected to enhance the remote monitoring of specific behaviors that affect patient health. In addition, PGHD use could support patients' decision-making on preventive care management, resulting in reduced medical expenses. However, sufficient evidence on the use and sharing of PGHD is lacking, and the impact of PGHD recording on patients' health behavior changes remains unclear. OBJECTIVE: This study aimed to assess patients' engagement with PGHD recording and to examine the impact of PGHD recording on their health behavior changes. METHODS: This supplementary analysis used the data of 47 postpartum women who had been assigned to the intervention group of our previous study for managing urinary incontinence. To assess the patients' engagement with PGHD recording during the intervention period (8 weeks), the fluctuation in the number of patients who record their PGHD (ie, PGHD recorders) was evaluated by an approximate curve. In addition, to assess adherence to the pelvic floor muscle training (PFMT), the weekly mean number of pelvic floor muscle contractions performed per day among 17 PGHD recorders was examined by latent class growth modeling (LCGM). RESULTS: The fluctuation in the number of PGHD recorders was evaluated using the sigmoid curve formula (R2=0.91). During the first week of the intervention, the percentage of PGHD recorders was around 64% (30/47) and then decreased rapidly from the second to the third week. After the fourth week, the percentage of PGHD recorders was 36% (17/47), which remained constant until the end of the intervention. When analyzing the data of these 17 PGHD recorders, PFMT adherence was categorized into 3 classes by LCGM: high (7/17, 41%), moderate (3/17, 18%), and low (7/17, 41%). CONCLUSIONS: The number of PGHD recorders declined over time in a sigmoid curve. A small number of users recorded PGHD continuously; therefore, patients' engagement with PGHD recording was low. In addition, more than half of the PGHD recorders (moderate- and low-level classes combined: 10/17, 59%) had poor PFMT adherence. These results suggest that PGHD recording does not always promote health behavior changes.

Pregnant women's migration patterns before childbirth after large-scale earthquakes and the added impact of concerns regarding radiation exposure in Fukushima and five prefectures.

The 2011 Great East Japan Earthquake (within Fukushima, Iwate, and Miyagi prefectures) was a complex disaster; it caused a tsunami and the Fukushima Daiichi Nuclear Power Plant accident, resulting in radiation exposure. This study investigated the earthquake's effects on the migration patterns of pregnant women and their concerns regarding radiation exposure. We also considered the following large-scale earthquakes without radiation exposure: Great Hanshin-Awaji (Hyogo prefecture), Niigata-Chuetsu, and Kumamoto. Pregnant women were categorized as outflow and inflow pregnant women. Data on the annual number of births three years before and after the earthquake were used as a denominator to calculate the outflow and inflow rates per 100 births. The odds ratios of annual outflow and inflow rates after the earthquake, using three years before the earthquake as the baseline, were calculated. The odds-ratio for outflow significantly increased for Hyogo, Fukushima, Miyagi, and Kumamoto prefectures after the earthquake, particularly for Fukushima, showing a significant increase until three years post the Great East Japan Earthquake (disaster year: odds-ratio: 2.66 [95% confidence interval: 2.44-2.90], 1 year post: 1.37 [1.23-1.52], 2 years post: 1.13 [1.00-1.26], 3 years post: 1.18 [1.05-1.31]), while the remaining three prefectures reported limited increases post one year. The inflow decreased after the earthquake, particularly in Fukushima, showing a significant decrease until 2 years post the Great East Japan Earthquake (disaster year: 0.58 [0.53-0.63], 1 year post: 0.76 [0.71-0.82], 2 years post: 0.83 [0.77-0.89]). Thus, pregnant women's migration patterns changed after large-scale earthquakes, suggesting radiation exposure concerns possibly have a significant effects. These results suggested that plans for receiving assistance and support that considers the peculiarities of disaster related damage and pregnant women's migration patterns are needed in both the affected and non-affected areas.

Premenstrual and menstrual symptomatology in young adult Japanese females who smoke tobacco.

AIM: The present study examines the correlation between premenstrual and menstrual symptomatology and smoking status in young adult Japanese females. MATERIAL AND METHODS: A cross-sectional study was conducted to assess premenstrual and menstrual symptomatology using the Moos Menstrual Distress Questionnaire (MDQ). Findings were compared between smokers and nonsmokers. The correlation between symptomatology and smoking status assessed by the Fagerström Test for Nicotine Dependency (FTND) and the Reasons for Smoking Scale (RSS), which identifies smoker's motives, was determined. RESULTS: Data were obtained from 785 participants, including 71 smokers, 29 quitters and 685 nonsmokers. All smokers consumed 20 or fewer cigarettes per day with the exception of one heavy smoker. Smoking status affected the cycle of menstruation, but did not affect the duration. Smokers demonstrated more severe symptomatology than nonsmokers during the menstrual and premenstrual phases. Among smokers, premenstrual symptomatology was significantly more severe than menstrual symptomatology. Five premenstrual symptom groups (pain, concentration, water retention, behavior change and negative affect) were significantly higher in smokers than in nonsmokers. Overall MDQ scores and those of three subcategories (concentration, behavior change, and negative affect) during the premenstrual phase were significantly correlated with nicotine dependency and smoking motives. Smoking motives were also correlated with the severity of autonomic reaction. CONCLUSION: Our findings suggest that young adult Japanese females with a light smoking habit have severe premenstrual symptomatology, which was correlated with nicotine dependency and smoking motives.
