RESUMO
OBJECTIVES: We aimed to clarify the accuracy of pregnant women's knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children. METHODS: A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women. We then investigated whether participants had knowledge regarding the risk of mother-to child transmission in these diseases and factors associated with their knowledge. RESULTS: We enrolled 2,838 respondents in this study. The rates of agreement for HBV and cervical cancer screening related to human papillomavirus infection were "substantial," those for syphilis was "moderate," and those for HCV and HTLV-1 were "fair," according to the Kappa coefficient. The rate of knowledge regarding mother-to-child transmission of syphilis was highest (37.0%); this rate for the other items was approximately 30%. Increased knowledge was associated with higher educational level and higher annual income. CONCLUSIONS FOR PRACTICE: Pregnant women in Japan had generally good levels of understanding regarding their results in early-pregnancy infectious disease screening. However, they had insufficient knowledge regarding mother-to-child transmission of these diseases. Health care providers should raise awareness in infectious disease prevention among pregnant women and the general public, providing appropriate measures and implementing effective perinatal checkups and follow-ups for infectious diseases.

AIM: Maternal vaccination is a promising strategy for protecting pregnant women and newborns against severe infections. This review aims to describe the current status and challenges associated with maternal vaccination against seasonal influenza, tetanus-diphtheria-pertussis (Tdap/DTaP), and novel coronavirus disease of 2019 (COVID-19) in Japan and other countries, mainly the United States and the United Kingdom. METHODS: A literature search was conducted in PubMed and other public websites (e.g., Centers for Disease Control and Prevention) to obtain information on maternal vaccination. RESULTS: Inactivated vaccines are recommended for pregnant women by gynecologic societies in Japan, the United States, and the United Kingdom. Among pregnant Japanese women, the influenza and COVID-19 (two doses) vaccine coverage rates were 27.0%-53.5% (six studies) and 73.6% (one study), respectively; there are no studies on maternal vaccination with DTaP. Concerns regarding vaccine safety are a major barrier to maternal vaccination across countries. Maternal vaccination is effective in preventing severe disease in pregnant women and protecting infants aged <6 months, is generally safe, and does not increase the risk of adverse maternal and fetal outcomes. Providing accurate information regarding vaccination through healthcare providers and the government and government funding for vaccines may help improve maternal vaccination rates in Japan. CONCLUSION: Current coverage for maternal vaccination is still low globally mainly because of vaccine hesitancy among pregnant women. The government, drug-regulatory authorities, and healthcare professionals must educate pregnant women about the effectiveness and safety of maternal vaccines and encourage vaccination when the benefits outweigh the risks.

AIM: The 2011 Great East Japan Earthquake (GEJE) was a disaster leading to radiation exposure and psychological distress, particularly among pregnant women. However, it is not known how this affected the seasonal changes of pregnancy and childbirth. Therefore, this study investigated the impact of the GEJE in the Fukushima Prefecture on spontaneous and induced abortions with regard to seasonal variability. METHODS: We used the data of vital statistics of live birth and stillbirth registry and the census survey of the Fukushima Maternity Care Facility. We calculated the spontaneous and induced abortion rate for 2011-2016 using two different methods (cross-sectional and longitudinal). We calculated the quartiles and outliers to determine the impact and duration of the GEJE. Periodicity was investigated using spectral density analysis. The data were analyzed for the entire Fukushima Prefecture and by region. RESULTS: The spontaneous abortion rate did not show specific changes after the GEJE. Contrarily, the monthly analysis in the cross-sectional method, revealed specific increases in induced abortion rate during the year after the GEJE; in the longitudinal method, induced abortions increased among women who became pregnant within 1 year after the GEJE. Spontaneous abortion showed no specific periodicity, while induced abortion showed cycles of 6 and 12 months, with a particular increase in May each year. CONCLUSIONS: The spontaneous abortion rate was not affected by the GEJE. The changes in the induced abortion rate after the disaster may have overlapped with the timing of the increased periodicity, and cannot be attributed solely to the GEJE.

AIM: This nationwide study aimed to investigate the practical management of term premature rupture of membrane (PROM) and its relationship with maternal and neonatal outcomes. METHODS: We conducted a questionnaire survey of 415 facilities participating in the Japan Perinatal Registry Network of the Japan Society of Obstetrics and Gynecology in 2016. The patients were women expecting vaginal birth after PROM at term without clinical chorioamnionitis. We classified the facilities into three groups based on duration of the expectant management after PROM (within 24, 24, and 48 h). Furthermore, we analyzed the association between perinatal outcomes and management protocol using the Japan Perinatal Registry Network Database 2016. RESULTS: Of 415 facilities, 346 (83.4%) completed and returned the survey. Among 231 facilities with management protocols, an interval of 3 days from PROM to delivery was acceptable in 167 facilities (72.3%). One hundred forty-nine facilities (64.5%) responded that they did not perform mechanical cervical dilation, and 90 (39.0%) used oxytocin as a uterotonic irrespective of cervical maturation. The number of hospitals that had a policy to administer antibiotics to Group B streptococcus-positive patients was 211 (91.3%). Neonatal outcomes at birth and the frequency of cesarean section and postpartum fever did not differ among the three groups. CONCLUSIONS: Most facilities in the Japan Perinatal Registry Network managed women at term to delivery within 3 days after PROM with attention to bacterial infection. Expectant management up to 48 h after PROM did not increase the risk of postpartum fever, compared to labor induction immediately after PROM.

AIM: The number of babies born with Down syndrome has changed in recent years because of widespread availability of prenatal screening and advanced maternal age at delivery. In Japan, which has no public institutions that record data on babies born with chromosomal abnormalities (including Down syndrome), the accurate number remains unknown. METHODS: The Japan Association of Obstetricians and Gynecologists Birth Defects Monitoring Program (hereafter the JAOG Program) is the only national survey of congenital anomalies in Japan. Using data from this survey and vital statistics, we investigated the changes in the number of babies born with Down syndrome in Japan from 2006 to 2019. RESULTS: On performing linear regression analysis with the proportion of babies born with Down syndrome as the response variable, and the proportion of mothers giving birth at the age of 35 years or older as the explanatory variable, the regression coefficient was 0.0054 (p < 0.001). The proportion of mothers giving birth at the age of 35 years or older was useful for predicting the proportion of babies born with Down syndrome. This proportion has increased since 2006 but has remained almost unchanged since 2015. In 2019, it was 1/734. CONCLUSIONS: This study revealed that the proportion of mothers giving birth at the age of 35 years or older strongly affected the proportion of babies born with Down syndrome. We assume that the proportion of babies is slightly affected by the increased number of pregnant women currently undergoing prenatal screening after the introduction of noninvasive prenatal genetic testing in 2013.

AIM: The aim of this study was to clarify the physical and mental burden of the COIVD-19 pandemic on obstetricians and gynecologists in Japan and to identify factors that increase the burden of their psychological stress. METHODS: A web-based questionnaire was sent to obstetricians and gynecologists in Japan via email and social media to collect voluntary responses. This survey was conducted from September 1 to 30, 2020. RESULTS: A total of 852 valid responses were included in the analysis; 76% (644) of the physicians felt that the COVID-19 pandemic caused them physical and mental stress equal to or greater than the most severe disaster they had ever experienced. Physicians who reported high mental and physical stress were more likely to be in areas with high numbers of infected patients (odds ratio (OR) 1.571, p = 0.012). Physicians experienced great stress to the point of wearing heavy personal protective equipment during routine vaginal deliveries by mothers with no COVID-19 symptoms. This trend was markedly pronounced for physicians working in regions with fewer cases of COVID-19 infection. CONCLUSIONS: Obstetricians and gynecologists who reported high mental and physical stress were more likely to be in areas with high numbers of infected patients. One potential reason for this may be that they were required to wear more personal protective equipment than necessary. Infection control methods that ensure the safety of obstetricians and gynecologists while not causing unnecessary physical or psychological stress are needed.

AIM: To evaluate psychological stress among pregnant and puerperal women in Japan during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: In this cross-sectional study, we recruited pregnant women and puerperal women who delivered between January and September 2020 in Japan, using an online questionnaire. Participants were divided into low, middle, and high groups according to the degree of the epidemic in their region of residence. Related factors were analyzed using the chi-squared test. The relationship between COVID-19 epidemic regions and depression risks and anxiety using the Edinburgh Postnatal Depression Scale (EPDS) and Kessler 6 scale (K6) was evaluated using a univariate and multivariable logistic regression model. RESULTS: Overall, 7775 cases, including 4798 pregnant and 2977 puerperal women, were analyzed. The prevalence of high EPDS and K6 scores was significantly increased in pregnant women in the high than those in the low epidemic regions (EPDS: adjusted odds ratio [aOR] 1.453, 95% confidence interval [CI] 1.205-1.753; K6: aOR 1.601, 95% CI 1.338-1.918). There was no difference in EPDS score, but the prevalence of high K6 scores was significantly increased in puerperal women in the high than those in the low epidemic regions (aOR 1.342, 95% CI 1.066-1.690). Further, restriction on going to their hometown for delivery increased the prevalence of high EPDS scores among pregnant (aOR 1.663, 95% CI 1.296-2.133) and puerperal women (aOR 1.604, 95% CI 1.006-2.557). CONCLUSIONS: Decreased support due to the COVID-19 pandemic affected the psychological status of pregnant and puerperal women; hence, investing medical resources in their healthcare essential.

AIM: Denosumab prevents osteoporosis by potently inhibiting bone resorption, but requires oral therapy with calcium and vitamin D preparations to prevent the side effects of hypocalcemia. Generally, a combination drug containing calcium, natural vitamin D, and magnesium is used. However, if activated vitamin D has been used before the initiation of denosumab therapy, continued use of activated vitamin D is not uncommon. This study aimed to evaluate the combination vitamin D preparation, alfacalcidol, and eldecalcitol on the therapeutic effect on denosumab therapy, the preventive effect on hypocalcemia, and the effect on renal function, to determine the optimal choice of concomitant medication. METHODS: This is a retrospective and single-center study. Among 39 patients who had used denosumab (60 mg dose) for at least 12 months between November 2013 and October 2015, those who used the combination medication concomitantly as the standard treatment, those who used alfacalcidol concomitantly, and those who used eldecalcitol concomitantly were compared. RESULTS: Denosumab therapy markedly increased lumbar spine and femoral neck bone densities at 12 months in the three groups, showing no particular difference in the rate of increase of bone density. The three groups had marked decreases in bone metabolism markers, but had no intergroup differences. No hypocalcemia, hypercalcemia, or obvious renal dysfunction occurred over 12 months. CONCLUSION: This study indicates that the use of activated vitamin D preparations, as concomitant medications with denosumab therapy, is appropriate considering the therapeutic efficacy of denosumab, prevention of hypocalcemia, and influence on renal function.

We aimed to determine the optimal gestational weight gain (GWG) in Japanese women with a Body Mass Index (BMI) ≥25 kg/m2. The present retrospective study investigated singleton pregnancies in 6,781 Japanese women registered in the Japan Society of Obstetrics and Gynecology system in 2013. We divided overweight and obese women into four GWG categories based on the Institute of Medicine (IOM) recommended: weight loss, small weight gain, within IOM criteria, and above IOM criteria. The adjusted odds ratios and predicted probabilities of maternal and neonatal outcomes of interest with weight change were calculated. In overweight women, GWG was associated with neonatal birth weight. In the loss and small gain subgroups, there was a significant increase in small for gestational age (SGA) and low birth weight neonates (LBW). Predicted probabilities showed the lowest risk was observed in a weight gain of 0 kg; the risk sharply increased at a gain of 11.5 kg. In obese women, weight gain increased the prevalence of large for gestational age (LGA) neonates; however; SGA was not associated with GWG. Predicted probabilities showed an increase in the risk with weight gain. The observed optimal GWG was 0 to 11.5 kg in overweight, and weight loss in obese, pregnant Japanese women.

AIMS: Placental abruption is an important cause of perinatal mortality and morbidity. Although there are many reports on the risk factors for placental abruption, there are few on its classification. Our aim is to evaluate the associations between primary symptoms and the outcomes of placental abruption. MATERIAL AND METHODS: We carried out a retrospective cohort study of 12,474 births at the Perinatal Center for Maternity and Neonates of the Yokohama City University Medical Center between January 2000 and December 2012. There were 151 women with placental abruption, 136 of whom were included in this study. The subjects were classified into two groups according to their primary symptoms: those with bleeding (external bleeding group) and those with abdominal pain (abdominal pain group). Maternal and neonatal outcomes were compared between the two groups. RESULTS: Both fetal and maternal outcomes were significantly poorer in the abdominal pain group than in the external bleeding group in terms of intrauterine fetal death (6.5% vs 33.3%, P < 0.001), perinatal mortality (8.1% vs 33.3%, P = 0.001), umbilical arterial pH < 7.1 (15.7% vs 57.1%, P < 0.001), bleeding volume, rate of blood transfusion, and disseminated intravascular coagulation incidence. CONCLUSIONS: This classification based on primary symptoms was found to be useful for predicting both maternal and neonatal outcomes of placental abruption.

AIM: The aim of this study was to elucidate the risk of poor pregnancy outcomes in women with adenomyosis by comparing their outcomes to those of women without uterine abnormalities. MATERIAL AND METHODS: The subjects were 36 women diagnosed with adenomyosis before pregnancy who were managed at a tertiary care center between January 2002 and December 2012. Our hospital database was retrospectively reviewed to identify pregnancy outcomes associated with adenomyosis. The control group consisted of 144 women without uterine abnormalities who gave birth during the same period and whose age at delivery was adjusted by applying propensity scores. Pregnancy outcomes were compared between the adenomyosis and control groups. The main outcomes were gestational age at delivery, preterm delivery, preterm premature rupture of membranes, fetal malpresentation, cesarean delivery, small-for-gestational age, 5-min Apgar score < 7, umbilical arterial pH < 7.1, and neonatal intensive care unit admission. The data are presented as medians (range) or frequencies (percentage). RESULTS: The adenomyosis group had significantly higher rates of preterm delivery (41.7% vs 12.5%), preterm premature rupture of membranes (19.4% vs 4.2%), small-for-gestational age (33.3% vs 10.4%), fetal malpresentation (27.8% vs 8.3%), and cesarean delivery (58.3% vs 24.3%), as compared with the control group. No significant differences were observed in 5-min Apgar score < 7 or umbilical arterial pH < 7.1 between the two groups. CONCLUSIONS: Pregnancies in women with adenomyosis were associated with a higher preterm delivery rate and more frequent occurrences of fetal growth restriction and fetal malpresentation, such that both pregnancy and delivery outcomes were poor.

AIM: To investigate the clinical features of gestational thrombocytopenia (GT) difficult to differentiate from immune thrombocytopenia (ITP) during pregnancy. METHODS: The January 2000-December 2012 hospital database was analyzed to identify women with ITP or GT (after excluding other possible causes of thrombocytopenia) among those first noted to have platelet counts of less than 100 000/µL during pregnancy. The maternal characteristics, platelet count fluctuations and pregnancy outcomes were compared between women with ITP and GT. RESULTS: There were 23 pregnancies (22 women) with thrombocytopenia (GT, 13; ITP, 10). The GT group included five twin pregnancies (38.5%), whereas all pregnancies of the ITP group were singleton pregnancies, with significantly more twin pregnancies in the GT group (P = 0.046). Thrombocytopenia in the first trimester occurred in 70% (7/10) of ITP cases and 23.1% (3/13) of even GT cases. The nadir platelet count was less than 70 000/µL in 100% (10/10) of ITP cases and 30.8% (4/13) of GT cases (P < 0.001). Maternal treatment was required in 80% (8/10) of ITP cases, but in none of the GT cases. The pregnancy outcomes were favorable in both groups, and no case required fetal treatment. CONCLUSION: Gestational thrombocytopenia with platelet counts of less than 10 0000/µL occurred more frequently in twin pregnancies. Although onset of thrombocytopenia in the first trimester and a platelet count of less than 70 000/µL is more common in ITP, these findings were not uncommon in GT. Differentiation between ITP and GT may be feasible only with post-partum changes in the platelet count.

OBJECTIVES: Systemic lupus erythematosus (SLE) flare and preeclampsia are difficult to differentiate from each other and occasionally coexist; This study aimed to analyze cases requiring termination of pregnancy due to SLE flare or preeclampsia and to elucidate the association between these two conditions; Methods. Out of 71 pregnancies in 60 women managed for SLE-complicated pregnancies who delivered at or after 22 weeks' gestation at a tertiary center, 7 pregnancies were terminated due to uncontrollable severe SLE flare or severe preeclampsia We retrospectively analyzed the clinical courses and laboratory findings of these 7 cases to determine whether their pathological conditions were attributable to SLE flare alone, preeclampsia alone, or the coexistence of these two conditions. RESULTS: One of the 7 cases had preeclampsia alone, two had SLE alone, and four had both conditions. The coexistence of preeclampsia and SLE was thus the most common condition. In cases with both conditions, SLE flare had preceded preeclampsia, thereby making treatment after delivery difficult. CONCLUSION: Severe SLE flare often preceded severe preeclampsia and worsened after delivery. When differentiating severe SLE flare from severe preeclampsia is difficult during pregnancy, women should be regarded as having SLE flare rather than preeclampsia and aggressively treated.

OBJECTIVE: To evaluate pregnancy outcomes in women with uterine anomalies by applying a method for diagnosing and classifying congenital uterine malformations. DESIGN: Retrospective study. SETTING: Tertiary care center. POPULATION: Ninety-four women with uterine anomalies who delivered after 22 gestational weeks. METHODS: Excluding the 14 women with a history of surgery and seven with one endometrial cavity, 73 women with two endometrial cavities were subdivided into those with two external uterine orifices (2-OS subgroup) and those with one external uterine orifice (1-OS subgroup). MAIN OUTCOME MEASURES: Pregnancy outcomes, such as preterm birth, abnormal fetal presentation, cesarean delivery and placental abruption. RESULTS: The 2-OS subgroup comprised women with a didelphic or complete septate uterus who had a significantly higher rate of cesarean delivery (91% vs. 18%, p < 0.001) than the control group (normal uterine morphology; n = 5763). The 1-OS subgroup comprised women with a bicornuate or incomplete septate uterus who had significantly higher rates of preterm birth (27% vs. 5%, p < 0.001) and placental abruption (14% vs. 0.7%, p < 0.001) than the control group. CONCLUSIONS: Classification of uterine anomalies by the number of uterine endometrial cavities and external uterine orifices is an easy and reliable means of predicting pregnancy outcomes.

AIM: To compare outcomes after emergency cerclage versus expectant management for prolapsed fetal membranes in women with cervical incompetency. METHODS: The January 2000-December 2012 hospital database was analyzed to identify women managed for prolapsed fetal membranes who did not have premature rupture of membranes, clinically discernible chorioamnionitis, or treatment-resistant uterine contractions from 15 to 26 weeks of gestation retrospectively. Durations of pregnancy prolongation and numbers of deliveries after 32 and 28 weeks were compared between women undergoing emergency cervical cerclage and those receiving expectant management. RESULTS: Fifteen of the 35 women underwent emergency cervical cerclage ('cerclage group'), while the other 20 were managed expectantly ('bedrest group'). In the cerclage group, median gestational ages at procedure and delivery times were 22.6 (15.9-26.1) and 32.4 (19.4-41.6) weeks, respectively. Median gestational ages on admission and at delivery in the bedrest group were 23.4 (21.1-26.4) and 26.0 (23.1-36.4) weeks, respectively. The median duration of pregnancy prolongation was 44 days (4-165) in the cerclage group and 12.5 days (2-93) in the bedrest group (P < 0.01). Numbers of deliveries after 28 and 32 weeks were both significantly higher in the cerclage than in the bedrest group (P < 0.05). CONCLUSION: In women with prolapsed fetal membranes but no signs of infection or painful uterine contractions, emergency cervical cerclage prolonged pregnancy duration as compared with expectant management.

AIM: To determine associations of maternal pre-pregnancy underweight with poor outcomes and evaluate how gestational weight gain affects risks for such outcomes in pre-pregnancy underweight Japanese women. METHODS: By analyzing the January 2001-December 2012 hospital database, we retrospectively identified 6954 women with pre-pregnancy normal weights (body mass index, 18.5-24.9 kg/m²) and 1057 pre-pregnancy underweight women (body mass index, <18.5 kg/m²) who delivered at the Perinatal Maternity and Neonatal Center of Yokohama City University. These women were stratified by weekly weight gain during the second/third trimesters to investigate associations of gestational weight gain with spontaneous preterm birth and small for gestational age (SGA). Spontaneous preterm birth and SGA incidences were compared with those of women meeting Institute of Medicine (IO M) guidelines to determine optimal weight gain in Japanese women. RESULTS: Preterm birth and SGA incidences were significantly higher in pre-pregnancy underweight than in pre-pregnancy normal weight women (4.6% vs 2.4% [P=0.005] and 13.9% vs 9.7% [P = 0.003], respectively). For pre-pregnancy normal weight women, preterm birth incidence was significantly higher in those with weight gain of less than 0.2 kg/week than in those IOM guidelines. For pre-pregnancy underweight women, preterm birth and SGA incidences were significantly higher in those with weight gain of less than 0.3 kg/week than in those meeting IOM guidelines. CONCLUSION: Preterm birth and SGA incidences did not differ significantly between pre-pregnancy normal weight women with weight gain of 0.2 kg/week or more and pre-pregnancy underweight women with weight gain of 0.3 kg/week or more, as compared to women meeting IOM guidelines. These results suggest that IOM guidelines for gestational weight gain may lack external validity in Japanese women.

AIM: This study aimed to determine whether mechanical cervical dilatation with a laminaria tent in women with premature rupture of membranes (PROM) at term may influence the maternal/neonatal outcomes. METHODS: We reviewed the medical records and histopathologic results of the placenta in 782 women with PROM at term. Of the 486 women seen prior to 2010 (group 1), 85 had Bishop scores of 5 or less and underwent insertion of laminaria tents (group A). In the 296 women admitted after 2010 (group 2), 27 had Bishop scores of 5 or less and underwent labor management without insertion of laminaria tents (group B). The patient characteristics, delivery course and neonatal outcomes were compared between the groups. RESULTS: There were no significant differences in the maternal age, percentage of nulliparas, body mass index, gestational age at delivery or Bishop score between the groups. The Bishop score improved from 2.5 to 6.1 after laminaria tent insertion in group A. However, there were no significant intergroup differences in the frequency of use of labor-inducing agents or the time interval from PROM to delivery. The incidence of clinical/pathological chorioamnionitis was not higher in group A than in group B. No significant differences were found in the Apgar scores, umbilical artery pH or frequency of asphyxia neonatorum between the groups. Mechanical cervical dilatation by laminaria tent insertion neither increased the incidence of infection nor contributed to improvement of the perinatal prognosis. CONCLUSION: Mechanical cervical dilatation does not provide any benefit for women with PROM at term.

OBJECTIVE: To examine the clinicopathological characteristics of pregnant women who presented with intermittent hemorrhage occurring throughout pregnancy until delivery. METHOD: A total of 24 women with intermittent hemorrhage occurring throughout pregnancy were categorized into two groups, a group with persistent subchorionic hematoma (PSH) and another with chronic abruption (CA), and the pregnancy outcomes were compared between the two groups. The data were expressed as medians (range). RESULTS: There were 18 women in the PSH group and 6 women in the CA group. The median gestational age at delivery was 27.9 (22.1-33.4) weeks in the PSH group and 32.9 (24.3-33.1) weeks in the CA group, revealing a significantly earlier gestational age at delivery in the former group (p = 0.014). The percentage of the women developing acute abruption tended to be higher in the CA group [66.7 % (4/6)] than in the PSH group [26.3 % (5/18)]. Small for gestational age (SGA) infants and neonatal chronic lung disease were seen at high incidences, but only in the PSH group [21.1 % (4/18) and 42.1 % (8/18), respectively]. CONCLUSION: PSH was associated with earlier gestational age at delivery, a higher incidence of SGA infants, and poorer pregnancy outcomes than CA.

In Japan, rubella antibodies are tested in all pregnant women to detect subclinical infections. This study aimed to assess the validity of measuring rubella antibodies for detecting subclinical rubella among pregnant women in Japan. This single-center retrospective study measured rubella hemagglutination inhibition (HI) titers and rubella-specific IgM antibody index (IgM) values. IgM values were measured by conducting enzyme immunoassay, and IgM-values >1.2 were considered positive. Of 14,965 included pregnant women, 186 (1.2%) were IgM-positive. Only one patient was clinically diagnosed with rubella (HI titer, 1:2,048; IgM value, 10) and developed fever and skin rash. She decided to terminate her pregnancy without undergoing repeated blood tests. Of the IgM-positive patients, 136 (73.1%) had rubella HI titers of < 1:256. The correlation coefficient between rubella HI and IgM titers was weakly positive (0.2527; P < 0.0001). This study showed that a single combination of rubella HI and rubella-specific IgM measurements alone could not detect subclinical rubella. Creating awareness among pregnant women by informing them that almost all rubella-specific IgM-positive individuals without symptoms are not acutely infected could decrease their anxiety and prevent unnecessary pregnancy termination.

INTRODUCTION: Many developed countries including Japan are experiencing declining birth rates, particularly in urban areas. A gap between the planned number of children and the actual number of children exists, that is attributed to various factors such as: childcare leave and employment policies, childcare services, financial support, husbands' contributions to household chores and childcare, marriage support, community, and couples' well-being. Therefore, we propose HAMA study for having a baby, parenting, and marriage life (HAMA = 'H'aving 'A' baby, parenting, and 'MA'rriage life) in Yokohama (an urban area) to examine these issues. METHODS AND ANALYSIS: In this large-scale cohort study, we will elucidate the actual situation of families and child-rearing in Yokohama, evaluate the current policies and propose future measures to prevent a decline in the birth rate. Overall, 10 000 young married couples (wives aged 20-39 years as of 2022) will be randomly selected, and a survey form will be sent to them annually. They will be followed-up for 5 years to examine the factors associated with the planned number of children, well-being of the couple, childcare support policies, externalisation of housework and childcare, fathers' participation in housework and childcare, wives' free time, loneliness and social connectedness, relationship with the spouse and if they are working, questions regarding their work style and work-life balance will also be included. Ultimately, a conceptual model of the planned number of children and associated factors will be developed. ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of Yokohama City University (reference number: 2022-10) and will be conducted following appropriate ethical guidelines. Opportunities to withdraw consent to participate in the survey are provided to participants. The results of this survey will be published as research papers in relevant journals and will be reported to the administration of Yokohama city and other agencies.
