With the aim of monitoring the mental and physical health of mothers and children following the Fukushima nuclear accident and providing them with necessary care, we have been conducting an annual survey of expectant and nursing mothers since 2011. The Pregnancy and Birth Survey is a mail-in survey of about 15,000 individuals, with a response rate of approximately 50.0% each year. In addition, because respondents to a survey conducted in the immediate aftermath of the disaster showed a particularly high rate of depression, follow-up surveys have been conducted at 4 years after childbirth. Reviewing the results of surveys from FY 2011 through FY 2018, we found that the prevalence of depressive symptoms among mothers was highest in the survey after childbirth and decreased over time. Data of follow-up surveys showed that the prevalence of depression was lower than immediately after childbirth and then decreased over time. The proportion of mothers with radiation anxiety was higher among respondents in the FY 2011 follow-up than in the FY 2014 follow-up, indicating the prolonged impact of the nuclear accident, especially among those who gave birth immediately after the disaster. Characteristics of mothers who received telephone parenting counseling included first delivery, caesarean section, living in evacuation zones, not being able to receive medical examinations as scheduled, and having radiation anxiety. Continuous care should be provided to mothers who gave birth immediately after the nuclear accident, including routine perinatal care and parenting support, provision of information on radiation, and long-term monitoring of their wellbeing.

There are limited studies on the long-term effects of natural/environmental disasters, especially nuclear disasters, on obstetric outcomes. This study aimed to review the results of perinatal outcomes immediately after the Great East Japan Earthquake (GEJE) and the Fukushima Daiichi Nuclear Power Plant accident, as well as their long-term trends over 8 years, in the Fukushima Health Management Survey. The annual population-based Pregnancy and Birth Survey is conducted as part of the Fukushima Health Management Survey. The Fukushima Prefecture government launched it to assess the health conditions of pregnant women and their neonates after the GEJE. The self-reported questionnaire was sent to 115,976 pregnant women by mail from January 2012, with 58,344 women responding to the questionnaire (50.3% response rate). Pregnancy complications, such as gestational hypertension, respiratory diseases, and mental disorders, increased in some women who were pregnant at the time of the earthquake and immediately after the earthquake. However, the direct effects on newborns, such as preterm birth, low birth weight, and congenital anomalies, were not immediately clear after the earthquake. Although there were significant differences in the occurrence of preterm birth and low birth weight among the districts, there was no change in the occurrences of preterm birth, low birth weight, or anomalies in newborns in Fukushima Prefecture from the fiscal year 2011 to the fiscal year 2018. Therefore, the long-term effects of the post-disaster radiation accident on perinatal outcomes are considered to be very small.

To identify factors, including mental health, associated with smoking relapse among women in Japan from pregnancy to early parenthood.Secondary analysis of data from an ongoing cross-sectional study conducted between 2013 and 2016.We mailed questionnaires to all women who received a maternal and child health handbook from a municipality in Fukushima Prefecture or who underwent a maternal health checkup and gave birth in Fukushima Prefecture.Of the 28,562 women who responded to the questionnaire, 6,747 who previously smoked and quit around the time they registered their pregnancies were included in the analysis.Participants were divided into groups according to smoking relapse status: a nonrelapse group, which included those who maintained smoking cessation, and a relapse group, which included those who quit smoking but later relapsed. We further classified the latter group into those who quit smoking before or after pregnancy registration. We used a logistic regression model with forced entry to calculate adjusted odds ratios.Of the 6,747 participants who previously smoked, 881 (13.1%) relapsed. Regardless of the timing of smoking cessation, younger age and living in a specific region of Fukushima Prefecture were associated with smoking relapse. Relapse was associated with symptoms of depression in participants who quit smoking before registration and with multiparity in participants who quit smoking after registration of their pregnancies.Support for women at risk of smoking relapse after pregnancy requires consideration of regional characteristics and incorporation of family and mental health support with a focus on younger women.

Postpartum depression is a serious problem not only for mothers, but also for their children and families. Evidence is scarce on the effectiveness of couple-targeted antenatal interventions aimed at preventing postpartum depression in Asia. Therefore, we implemented an antenatal parenting support program from Australia ("empathy program") at three sites in Japan, and assessed the characteristics of participating couples and changes in their mental health indicators before and after the program (during pregnancy and 6 weeks postpartum, respectively). In this program, participant couples discussed concerns during pregnancy and a "difficult day" scenario with other same-gender participants and then with their own partners. In total, 100 couples attended the program. Among 60 participating mothers, 20% screened positive for maternal depression symptoms (defined as an Edinburgh Postnatal Depression Scale greater than 9). Changes in paternal empathy and maternal antenatal Edinburgh Postnatal Depression Scale score were significantly associated with maternal postpartum Edinburgh Postnatal Depression Scale score in multivariable analyses. Our results indicate that a key in preventing postpartum depression is paternal involvement and long-term support from antenatal phase.

The Pregnancy and Birth Survey was started by Fukushima Medical University as part of the Fukushima Health Management Survey in 2011 in order to assess the physical and mental health of mothers and provide parenting support (telephone counseling) for those in need. The present study reviewed the major findings from 4 annual surveys conducted from 2011 to 2014. Overall proportions of preterm deliveries, low birth weight infants, and congenital anomalies in the first year were almost the same as those in national surveillance data. The prevalence of depressive symptoms among the mothers held steady at about 25% over the 4 years. Regarding the content of parenting counseling, the proportion of mothers who voiced concerns about radiation decreased each year. This survey should be continued to provide support to mothers in Fukushima.

Objectives The objective of this study was to assess the frequency of and factors associated with infant feeding methods after the Fukushima nuclear power plant accident using data from the Fukushima Health Management Survey. Methods We conducted an anonymous self-administered questionnaire survey of 16,001 women who gave birth around the time of the Great East Japan Earthquake and registered their pregnancies at Fukushima Prefecture municipal offices between August 1, 2010 and July 31, 2011. The responses of 8366 women were analyzed. Chi square tests and multiple logistic regression analysis were used to compare various factors between women who had formula-fed their children because of concern regarding radioactive contamination or other reasons and those who had breastfed exclusively. Results The percentage of women who had breastfed exclusively was 30.9 %. The percentage of women who had both breastfed and formula-fed or formula-fed exclusively was 69.1 %, of which 20.3 % formula-fed because of concern regarding radioactive contamination of breast milk. The use of formula feeding because of concern about radioactive contamination was significantly higher in women who had resided within the evacuation area and those whose regular antenatal care had been interrupted. The use of formula feeding for other reasons was significantly higher in women who had resided within the evacuation area and lower for those who had willingly switched to another medical institution. Conclusions for Practice Our results suggest the importance of providing breastfeeding support to women who are forced to evacuate or whose antenatal care is interrupted after a disaster.

This study aimed to clarify the frequency of and temporal changes in the content of mothers' free written opinions obtained in the Fukushima Health Management Survey Pregnancy and Birth Survey from 2011 to 2013. A self-administered questionnaire was mailed to women who delivered babies in Fukushima Prefecture. The questionnaire asked about maternal and child health. Expression of mothers' concerns about radiation decreased over time. Common to the top 5 codes across the 3 years were "radiation effect on fetus and infant" and "information provision including survey results." Participants who wrote free opinions were significantly more likely to be aged ≥30 years and to have depressive symptoms. Our descriptive analysis of the qualitative data showed a clear shift in mothers' concerns from radiation-related issues to their own physical and mental health. Mothers who expressed concerns were more likely to report negative physical and mental health.

The Pregnancy and Birth Survey of the Fukushima Health Management Survey is a questionnaire survey that has been conducted annually since 2011 in Fukushima Prefecture. Since 2016, the survey has been available online as well as in paper form. This study aimed to determine whether making the survey available online improved response rates and to identify the characteristics of paper and online survey respondents and their results. Using LimeSurvey, we constructed an online survey environment that enabled responses via computer or mobile device. Respondents could choose whether to respond on paper or online. The response rate for the 2016 survey was 51.8%, an increase of 3.5% over the previous year. Of these responses, 15.8% were made online. Online respondents were mostly primiparous. Further, while there was no difference in the percentage of respondents who provided free responses, the amount written was higher in paper surveys than in online surveys. The combination of paper and online surveys increased convenience for respondents and contributed to improved response rates. In addition, paper surveys were superior in terms of allowing respondents to express their feelings and opinions.

The aim of this study was to produce monoclonal antibodies specific for neurones that are generated earliest in the rat neocortex. One of the established clones, K1, showed a strong immunoreactivity in the marginal zone at the 19th day of gestation (E19). The immunoreactivity of K1 initially appeared in the primordial plexiform layer at E15, in the subplate at E16, and in the marginal zone by E17. It became undetectable in the first postnatal week. The immunoreactivity was not detected in the neocortex of adults or elderly. Western blotting analysis revealed reactive bands at positions corresponding to proteins of 290 and 280 kDa for the neocortical membrane fractions prepared from E16 to E21 embryos. In these stages, smears of bands were also found at positions corresponding to higher molecular weights. A single band of protein of 280 kDa was detected for the soluble fractions prepared from the embryos at E19 and E21. These reactivities were susceptible to protease, but not to enzymatic or chemical destruction of carbohydrate residues. Electron microscopic analysis showed that the K1 immunoreactivity was detected primarily on the cellular membranes of neurites. In the marginal zone at E19, the K1 immunoreactivity was localised where neurites make contact with other neurites or somata. A portion of these contact points had typical features of synapses. In the cortical plate of the same stage, arrays of tiny K1-immunoreactive puncta were observed on a subset of radial processes. These results suggest that monoclonal antibody K1 is a marker recognising neurites of subplate neurones that extend radially and make neuronal contacts in the marginal zone.

A monoclonal antibody, K1, immunostains neurones generated earliest in the rat neocortex. The K1 immunoreactivity was found in both mouse and human embryos. In the human marginal zone, the subpial granular layer and the inner sublayer were stained at the 19th and 20th week of gestation, respectively. Western blot analysis revealed that the K1 immunoreactivity was conserved in a variety of vertebrates. While a protein of low molecular weight (200 kDa) reacted dominantly in an amphibian (Xenopus laevis) and a reptile (Agkistrodon blomhoffii), proteins of higher molecular weights (280 and 290 kDa) reacted dominantly in mammals (mouse, rat and macaque). In the brain of the reptile (Lacerta triliniata) embryo, K1 stained a marginal part of the superficial molecular layer in the dorsal cortex that is probably homologous to the mammalian marginal zone in the neocortex. In the chick embryo at the 8th day of incubation, the immunoreactivity was observed on neurones generated earliest in the dorsal cortex but not in the superficial molecular layer. The dorsal ventricular ridge and pallial thickening in either the reptile or chick were not stained. The K1 antigen could be a good marker for evolutional study of the mammalian neocortex.
