RESUMEN
In newborn screening (NBS), it is important to consider the availability of multiplex assays or other tests that can be integrated into existing systems when attempting to implement NBS for new target diseases. Recent developments in innovative testing technology have made it possible to simultaneously screen for severe primary immunodeficiency (PID) and spinal muscular atrophy (SMA) using quantitative real-time polymerase chain reaction (qPCR) assays. We describe our experience of optional NBS for severe PID and SMA in Osaka, Japan. A multiplex TaqMan qPCR assay was used for the optional NBS program. The assay was able to quantify the levels of T-cell receptor excision circles and kappa-deleting recombination excision circles, which is useful for severe combined immunodeficiency and B-cell deficiency screening, and can simultaneously detect the homozygous deletion of SMN1 exon 7, which is useful for NBS for SMA. In total, 105,419 newborns were eligible for the optional NBS program between 1 August 2020 and 31 August 2023. A case each of X-linked agammaglobulinemia and SMA were diagnosed through the optional NBS and treated at early stages (before symptoms appeared). Our results show how multiplex PCR-based NBS can benefit large-scale NBS implementation projects for new target diseases.

AIM: This study aimed to determine the weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy body mass index (BMI) and make recommendations for optimal weight gain in Japan. METHODS: The Japan Society of Obstetrics and Gynecology perinatal database for 2015-2017 was used. From the 719 723 deliveries included in this database, parturients with underlying diseases or missing data were excluded, and 419 114 deliveries were analyzed. A questionnaire survey was also conducted to weigh each perinatal adverse event. For each of the nine outcomes, a restricted cubic spline model was made to estimate the association between the "expected gestational weight gain at 40 weeks" and the outcome risk. RESULTS: Since the classes of medical facilities were generally the same, weights were assigned according to the mean of the questionnaires rather than by the class of the facility. For each pre-pregnancy BMI, the weight gains during pregnancy that minimized the predicted probability of various adverse perinatal events were 12-15, 10-13, 7-10, and upper limit of 5 kg for the underweight, normal-weight, obese 1, and obese ≥2 groups, respectively. CONCLUSIONS: The weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy BMI was established.

OBJECTIVES: The objective of the study was to compare the efficacy of intravenous immunoglobulin (IVIG) therapy for obstetric antiphospholipid syndrome (APS) refractory to conventional treatment. METHODS: We conducted a single-arm, open-label multicentre clinical intervention trial. The enrolled criteria were patients with refractory APS who had a history of still or premature birth before 30 weeks of gestational age, even though they had been treated with conventional treatment, i.e. heparin and low-dose aspirin. After confirming the foetal heartbeats, a single course of IVIG (0.4 g/kg body weight daily for 5 days) was added to conventional treatment. The primary outcome was a live birth ratio of >30 weeks of gestational period, and the secondary outcome included improving pregnancy outcomes compared to previous pregnancy. RESULTS: Twenty-five per cent of patients (2 of 8 cases) achieved a live birth after the 30th week of pregnancy by IVIG-only add-on treatment, which is the same prevalence as the historical control. However, by adding other second-line therapy to IVIG and conventional treatment, further three patients (37.5%) achieved improvements in pregnancy outcome compared to previous treatments. In total, five patients (62.5%) were able to achieve preferable pregnancy outcomes through combination treatment including IVIG. CONCLUSIONS: This clinical trial could not demonstrate the efficacy of IVIG-only add-on therapy at improving the pregnancy outcomes of patients with obstetric APS refractory to conventional treatment. However, the combination of IVIG with rituximab or statins adding to conventional treatment improved pregnancy outcomes and resulted in more live births. Further studies are needed to investigate the efficacy of multi-targeted therapy to treat obstetric refractory APS.

AIM: To clarify the state of screening and support systems for socially high-risk pregnant women at obstetric facilities across Japan and identify the characteristics of facilities related to the implementation of screening. METHODS: This cross-sectional study used a self-administered questionnaire. Participants were managers of hospitals, clinics, and midwifery birth centers handling deliveries in 47 prefectures across Japan. The questionnaire comprised items regarding the characteristics of participants and their facilities, service provision related to socially high-risk women available at the facility, the number of specified pregnant women (tokutei ninpu) per year, methods of screening, and support systems within the obstetric facilities. Descriptive statistics and multivariate logistic regression analysis were performed using IBM-SPSS version 24 for the association between facility characteristics and screening practices for socially high-risk pregnant women. RESULTS: Valid responses were received from 716 of 2512 obstetric facilities. Rates of specified expectant mothers per annual number of deliveries were identified as follows: perinatal medical centers (2.7%), general hospitals (1.6%), obstetrics and gynecology hospitals (1.0%), and clinics (0.8%). A total of 426 facilities (60.6%) reported screening all expectant mothers to identify socially high-risk pregnant women. Multiple logistic regression analysis revealed that facility characteristics and service/care provision related to screening practices included availability of in-hospital midwife-led care and in-hospital midwifery clinics (adjusted odds ratio 1.61; 95% CI [1.30, 1.47]), one-on-one care by midwife (1.73; 95% CI [1.15, 2.59]), multidisciplinary meetings within the facility (1.70; 95% CI [1.14, 2.56]), follow-up support systems after discharge (1.90; 95% CI [1.17, 3.09]), and participation in the regional council for children in need of protection (2.33; 95% CI [1.13, 4.81]). CONCLUSIONS: Approximately 60% of surveyed obstetric facilities screen for socially high-risk women. Increasing service provision at facilities may be necessary to implement screening.

BACKGROUND: Evidence on the association between severe maternal morbidity (SMM) and mother-infant bonding and self-harm ideation is limited. We aimed to examine these associations and the mediating effect of Neonatal Intensive Care Unit (NICU) admission at one-month postpartum. METHODS: This multicenter, prospective cohort study was conducted in Japan (n = 5398). SMM included preeclampsia, eclampsia, severe postpartum hemorrhage, placental abruption, and a ruptured uterus. Lack of affection (LA) and Anger and Rejection (AR) were assessed using the Mother-Infant Bonding Scale (MIBS), and self-harm ideation was assessed using the 10th item of the Edinburgh Postnatal Depression Scale (EPDS). Linear and logistic regression models were used to examine the association between SMM and MIBS score and self-harm ideation. A structural equation model (SEM) was employed to examine the mediating effect of NICU admission on the association between SMM and mother-infant bonding and postpartum depressive symptoms. RESULTS: Women with SMM had a 0.21 (95 % confidence interval [CI]: 0.03-0.40) point higher MIBS score and a decreasing trend in the risk of self-harm ideation (odds ratio 0.28, 95 % CI: 0.07-1.14) compared to those without SMM. SEM analysis revealed that SMM was associated with MIBS partially through NICU admission. LIMITATIONS: EPDS scores during pregnancy could be an unmeasured confounder. CONCLUSIONS: Women with SMM had higher MIBS scores, particularly on the LA subscale, which was partially mediated by NICU admission. Psychotherapy to support parent-infant relationships is necessary for women with SMM.

BACKGROUND: Adverse child experiences (ACEs), childhood maltreatment and household dysfunction, are risk factors of hyperglycemia in pregnancy (HIP), including diabetes before pregnancy, gestational diabetes (GDM), and overt diabetes in pregnancy, through increased risk of unhealthy behaviors, obesity, and stress response system dysfunction. While ACEs are often difficult to be assessed in hospital settings, parent-daughter relationship, that is, pregnant women's relationship with their parents can be considered as a measurable maker for ACEs that may be associated with HIP. The purpose of this study is to examine the association between poor parent-daughter relationship and HIP. METHODS: Hospital-based prospective cohort study was conducted in Japan (N = 6,264). Women visiting participating 58 facilities for delivery between April 2019 and March 2020 were included. Parent-daughter relationship was assessed by a questionnaire asking whether participants were satisfied with their relationship with their parents. HIP was diagnosed based on the criteria used in Japan. A multiple logistic regression model was applied to adjust for covariates. RESULTS: Pregnant women who were not very satisfied and not satisfied at all with the relationship with their parents, and HIP were 343 (5.5%), 74 (1.2%), and 274 (4.4%), respectively. Pregnant women who were not very satisfied with their parent-daughter relationship showed a significant positive association with HIP in the crude model (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.11-2.63). When stratified by psychiatric disease history, we found a significant positive association among those without psychiatric disease history (OR: 1.77, 95% CI: 1.11-2.84), but not among those with psychiatric disease history (OR: 0.61, 95% CI: 0.16-2.28). CONCLUSIONS: Poor parent-daughter relationship was associated with the risk of HIP among pregnant women without psychiatric disease history, suggesting that this simple question could be used to estimate the risk of HIP when it was challenging to inquire directly about ACEs. Further research is needed to elucidate the mechanism of the association.

OBJECTIVE: To clarify the relationship between the number of deliveries and maternal outcomes in Japan, considering the declining birth rate and the evidence that hospitals with few deliveries have medical safety issues. METHODS: Hospitalizations for deliveries were analyzed using the Diagnosis Procedure Combination database from April 2014 to March 2019, after which maternal comorbidities, maternal end-organ injury, medical treatment during hospitalization, and hemorrhage volume during delivery were compared. Hospitals were divided into four groups based on the number of deliveries per month. RESULTS: A total of 792 379 women were included in the analysis, among whom 35 152 (4.4%) received blood transfusions, with a median blood loss of 1450 mL during delivery. Regarding complications, pulmonary embolism was significantly more frequent in hospitals with the lowest number of deliveries. CONCLUSION: Using a Japanese administrative database, this study suggests an association between hospital case volume and the occurrence of preventable complications, such as pulmonary embolisms.

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: Low-dose aspirin (LDA) has been shown to reduce the incidence of preeclampsia (PE). Previous studies have focused on the timing of LDA initiation, but no study to date has assessed the timing of LDA discontinuation. This study aimed to evaluate the effect of LDA when LDA is initiated between 12 and 16 weeks of gestation and continued until 28 weeks of gestation. METHODS: This prospective cohort study with historical controls investigated singleton pregnancies that were at a high risk for PE. High-risk factors were defined as a history of hypertensive disorders of pregnancy, chronic hypertension, diabetes mellitus, autoimmune disease, obesity, and high normal blood pressure in the first trimester. We performed adjustments using propensity score matching (PSM) for each indication of LDA, maternal age, primiparity, and assisted reproductive technology. The primary outcome was the incidence of PE. Secondary outcomes were the incidence of preterm PE, fetal growth restriction (FGR), preterm birth, fetal malformation, and maternal postpartum hemorrhage (PPH). RESULTS: A total of 203 and 543 participants were assigned to the LDA and control group, respectively. After PSM, there was no significant difference in the incidence of PE (22.0% vs. 16.8%; p = 0.20), preterm PE (12.0% vs. 13.1%; p = 0.76), FGR (7.9% vs. 12.0%; p = 0.17), or preterm birth (17.3% vs. 15.7%; p = 0.68). There was also no significant increase in maternal PPH or in the incidence of fetal malformations. CONCLUSION: Discontinuing the use of LDA at 28 weeks of gestation did not result in a lower incidence of PE and FGR.

Backgrounds: A history of childhood abuse and subsequent poor relationship with parents in adulthood among pregnant women is a known risk factor for postpartum depression (PPD). Although parent-daughter relationship can change during pregnancy, little is known whether the trajectories have an impact on PPD. The aim of this study is to examine whether trajectories of parent-daughter relationship during pregnancy are associated with PPD in Japanese mothers. Methods: In a hospital-based prospective cohort study conducted in Japan, 4,772 women were followed from their first visit to their 1-month postpartum check-up (follow-up rate: 77.4%). Parent-daughter relationship was assessed whether participants were satisfied with their parents at first visit and after delivery. We defined four parent-daughter relationship trajectory categories: consistently satisfied, improving, deteriorating, and consistently unsatisfied. PPD was assessed by the Edinburgh Postnatal Depression Scale. Logistic regression model was applied to adjust covariates. Results: There were 129 (2.7%), 122 (2.6%), and 181 (3.8%) cases of improving, deteriorating, and consistently unsatisfied relationship, respectively. Compared to the group that was consistently satisfied, pregnant women of the deteriorating and consistently unsatisfied group showed 2.81 (95% CI: 1.73-4.55) and 2.39 (95% CI: 1.58-3.62) times, respectively, more likely to show PPD after adjustment for confounders. Conclusion: Women who felt that their relationship with parents "deteriorated" or was "consistently unsatisfactory" during pregnancy showed significant risk of PPD. Paying attention to the pregnant women's feelings about the relationship with their parents and promoting positive change may help predict and prevent PPD.
RESUMEN
OBJECTIVE: To develop and validate the Social Life Impact for Mother (SLIM) scale to identify mothers in Japan who need social support postpartum. METHODS: Hospital-based prospective study was implemented nationwide in Japan. A total of 7462 pregnant women completed the SLIM scale in their first trimester, and postpartum social problems (postpartum depression and bonding disorders) were assessed at 1 month after delivery (N = 5768, follow-up rate 77.3%). Multivariate logistic regression was applied to investigate the association between SLIM scale and postpartum social problems. RESULTS: The SLIM scale is made up of nine risk factors for postpartum social problems, including relationship problems, lower financial status, and lack of social support. The SLIM scale predicted postpartum social problems with moderate accuracy (area under the curve 0.63, 95% confidence interval 0.60-0.65). Further stratification by local clinic and tertiary hospital did not affect the estimates. CONCLUSION: The SLIM scale at prenatal check-up may be useful for obstetricians to detect mothers with postpartum social problems. Further intervention studies using the SLIM score are warranted.

OBJECTIVE: To elucidate the impact of the intended delivery mode on long-term outcomes among extremely preterm infants. MATERIALS AND METHODS: Women who delivered singletons between 23 0/7 and 25 6/7 weeks of gestation from January 2010 to March 2014 and their infants were included in this study. The cases of fetal growth restriction and those with a chromosomal or major structural abnormality were excluded. The cases of fetal death that was diagnosed before labor onset and cases of non-reassuring fetal status, placental abruptions or umbilical cord prolapse that was diagnosed at labor onset were also excluded. The primary outcome was the incidence of composite adverse events, including death, cerebral palsy, or neurodevelopmental delay, at the age of three years. The composite adverse events, including death, grade III or IV intraventricular hemorrhage, cystic periventricular leukomalacia, necrotizing enterocolitis, focal intestinal perforation, and sepsis of neonatal period, were assessed as short-term outcomes. The association between the intended delivery mode and primary outcome, short-term outcome, and each component was analyzed using a multivariate logistic regression model. RESULTS: Eighty cases were included in the analyses. Primary outcomes could be assessed in 72 cases. Infantile composite adverse events before discharge were observed in 19 cases (24%). The prevalence of primary outcomes was 40% (29 cases). The intended delivery mode was not associated with primary and short-term outcomes and each component complication. CONCLUSION: An advantage of intended cesarean delivery in terms of prognosis at three years of age in extremely preterm infants was not observed.

AIM: To investigate the incidence of complications associated with cervical cerclage by indication. METHODS: This was a retrospective cohort study of women with singleton pregnancies who underwent cervical cerclage in a single perinatal center between 2008 and 2019. The participants were divided into three groups according to indication: history-indicated cerclage (HIC) group, ultrasound-indicated cerclage (UIC) group, and physical examination-indicated cerclage (PEIC) group. The incidences of perioperative complications within 2 weeks after the procedure, including intraoperative rupture of membranes, intraoperative bleeding, anesthesia complications, clinical chorioamnionitis, premature rupture of membranes (PROM), preterm delivery, and displacement of the suture, and those of peripartum complications, including difficult suture removal and cervical laceration, for each group were compared using Fisher's exact test or Pearson's chi-square test. Factors associated with severe adverse event, defined as PROM or delivery within 2 weeks after the procedure, were analyzed using multivariate logistic regression analysis. RESULTS: A total of 279 women (HIC, 38; UIC, 96; PEIC, 145) were enrolled. The incidence of perioperative complications was different among the three groups (7.9%, 10.4%, and 27.6%, respectively; p < 0.01), whereas that of peripartum complications was similar (18.4%, 11.5%, and 12.4%, respectively; p = 0.54). Severe adverse events occurred only in PEIC group, with an incidence of 18.6%. The associated factor for severe adverse events in PEIC group was prolapsed membranes into the vagina. CONCLUSIONS: Incidences of perioperative complications of cerclage differed among the indications. Women who underwent PEIC had higher risk of severe adverse events, especially when accompanied with prolapsed membranes into the vagina.

OBJECTIVES: Various patterns of Doppler deterioration exist in fetal growth restriction (FGR). However, the factors that differentiate these patterns are still unknown. The purpose of this study was to clarify the perinatal outcomes and factors to determine the pattern of Doppler deterioration in severe FGR. MATERIALS AND METHODS: We conducted a retrospective cohort study of preterm severe FGR with Doppler abnormality, wherein the clinical features, including maternal characteristics, medical history, and sonographic findings, were compared between the patterns of Doppler deterioration. We used the multivariable logistic regression analyses to identify the factors associated with the pattern of Doppler deterioration. RESULTS: Of 322 eligible fetuses, 143 had Doppler abnormalities. Fetuses with Doppler deterioration from ductus venosus uniquely featured fetal and placental-umbilical abnormalities detected after birth. Gestational age (GA) at diagnosis of FGR and at the first diagnosis of Doppler abnormality in fetuses with Doppler deterioration from middle cerebral artery (MCA) were later than those from umbilical artery. In addition, the factor associated with Doppler deterioration from MCA was 31-week GA at the first diagnosis of Doppler abnormality (adjusted odds ratio [aOR]: 26.7; 95% CI: 8.35-103), not GA at diagnosis of FGR (aOR: 1.82; 95% CI: 0.50-5.96). CONCLUSIONS: Characteristics of each Doppler deterioration pattern might reflect FGR etiology. Undetectable anomalies and umbilical-placental abnormalities were found in fetuses with Doppler deterioration from the ductus venosus. Doppler deterioration from the MCA was observed after 31 weeks of gestation not only in the late-onset FGR but also in the early-onset FGR with normal umbilical artery Doppler findings.

BACKGROUND: Complex anorectal malformations (ARMs) are a group of rare congenital malformations involving numerous anomalies that require reconstruction and can affect sexuality, fertility, and pregnancy outcomes. Few cases of pregnancy in complex ARM patients have been reported. CASES: We report on 2 patients with ARMs who delivered 3 term infants, all by cesarean section with successful collaboration between pediatric urologists and obstetricians. Both patients fully recovered with no long-term consequences after experiencing maternal morbidities including urinary infections, clitoral abscesses, vaginal lacerations, extensive adhesive disease, bladder injury, and maternal hemorrhage. SUMMARY AND CONCLUSION: In managing pregnancies and deliveries in women with complex ARMs, coordination between obstetricians, pediatric urologists, and pediatric surgeons is crucial.

PURPOSE: To clarify the relationship between light vaginal bleeding (LVB) before physical examination-indicated cerclage (PEIC) and perinatal adverse outcomes. METHODS: This was a retrospective cohort study involving 94 singleton pregnancies undergoing PEIC <26 weeks of gestation at a single perinatal medical center between 2008 and 2015. The primary outcome was set as spontaneous preterm birth (sPTB) <34 weeks of gestation. The secondary outcomes were set as the second-trimester loss prior to 22 weeks of gestation, sPTB before 28 weeks of gestation, sPTB before 37 weeks of gestation, and stillbirth or neonatal death. Relationships between LVB and adverse outcomes were evaluated using logistic regression analysis. RESULTS: Preoperative LVB was detected in 16 cases (17.0%). Multivariate logistic regression analyses revealed that preoperative LVB was an independent risk factor for sPTB <34 weeks of gestation (adjusted odds ratio [aOR]: 8.42; 95% confidence interval [CI]: 1.72-41.1; p < .01), sPTB <28 weeks of gestation (aOR: 5.98; 95% CI: 1.67-21.4; p < .01) and perinatal death (aOR: 8.47; 95% CI: 1.11-64.5; p = .04). CONCLUSIONS: Vaginal bleeding prior to PEIC, even nonsignificant or self-limiting, is associated with sPTB before 28 or 34 weeks of gestation and perinatal death.

AIM: Streptococcal toxic shock syndrome is associated with the highest infection-related maternal mortality rates. We conducted a comparative analysis of the background factors and treatment course between survivors and nonsurvivors to improve our understanding concerning the optimal initial treatment approach for this fulminant disease. METHODS: This retrospective observational study was conducted based on clinical data collected from two national organizations. Clinical data of patients who died or survived (i.e. background information, clinical course and treatment administered) were collected. RESULTS: Records of 13 dead and 15 surviving patients were collected and analyzed. No statistically significant differences were found between the groups regarding age, parity, season, gestational age or the patients' location at the onset of symptoms. After the initial symptom onset, the survivors received antibiotics more systematically during their first visit to a clinic (P = 0.006). More survivors had received treatment within 1 h of onset of fulminant disease (P = 0.069). The number of fetal deaths was significantly higher in the mortality group (P = 0.003), while the fetal survival number was higher in the group of maternal survivors (P = 0.055). Maternal survivors with nonspecific initial symptoms received early intervention when there was a family history of group A streptococcal infection or a positive rapid antigen test result. CONCLUSION: Intensive care, including systemic antibiotic administration, may contribute to maternal survival when administered immediately (within 1 h) after the fulminant streptococcal toxic shock syndrome onset. Eliciting a family history of streptococcal infection and conducting a rapid antigen test can identify the patients needing early intervention.

AIM: The primary aim of this study was to examine the association between maternal height and mode of delivery in nulliparous Japanese women. The secondary aim was to examine the association between maternal height and maternal and neonatal morbidities. METHODS: This retrospective cohort study included women who gave birth at Osaka Women's and Children's Hospital, a tertiary perinatal center in Japan, from January 2015 to December 2017. Nulliparous Japanese women with singleton gestation, who went into labor at term were included in the study. The primary outcome was mode of delivery, and the secondary outcomes were maternal and neonatal morbidities. The relationships between maternal height and the outcomes were evaluated using multivariate logistic regression analysis adjusted for potential confounders. Maternal height was categorized into five groups with 5-cm increments for the analysis. RESULTS: A total of 1593 women were analyzed in this study. Shorter women had higher rate of cesarean delivery (CD) than taller women. There were no significant differences in the rates of operative vaginal delivery, maternal morbidity and neonatal morbidity among the maternal-height groups. The adjusted odds ratios (95% confidential interval) of maternal heights of <150 cm, 150-154 cm, 160-164 cm and ≥165 cm for CD, compared with a maternal height of 155-159 cm, were 3.56 (1.79-7.09), 1.68 (1.06-2.64), 0.63 (0.40-1.00) and 0.57 (0.30-1.01), respectively. CONCLUSION: Shorter nulliparous Japanese women were more likely to undergo intrapartum CD. However, the rates of maternal and neonatal morbidities in shorter women were similar to those in taller women.
RESUMEN
This study aimed to investigate whether watching an educational video on infant crying and the dangers of shaking and smothering within 1 week after delivery at maternity wards reduces self-reported shaking and smothering, at a 1-month health checkup. A cluster randomized controlled trial, stratified by area and hospital function, was employed in 45 obstetrics hospitals/clinics in Osaka Prefecture, Japan. In the intervention group, mothers watched an educational video on infant crying and the dangers of shaking and smothering an infant, within 1 week of age, during hospitalization at maternity wards, without blinding on group allocation. Control group received usual care. A total of 4722 (N = 2350 and 2372 for intervention and control group, respectively) mothers who delivered their babies (still birth and gestational age < 22 weeks were excluded) between October 1, 2014, and January 31 were recruited. Outcomes were self-reported shaking and smothering behaviors, knowledge on infant crying and shaking, and behaviors to cope with infant crying, assessed via a questionnaire at a 1-month health checkup. In all, 2718 (N = 1078 and 1640) responded to the questionnaire (response rate: 58.3%), and analytic sample size was 2655 (N = 1058 and 1597 for intervention and control group, respectively). Multilevel analysis was used to adjust for correlation within the cluster. Prevalence of shaking was significantly lower in the intervention group (0.19%) than in the control group (1.69%). Intention-to-treat analysis showed an 89% reduction in the reported prevalence of self-reported shaking (OR: 0.11, 95% CI: 0.02-0.53) due to watching the educational video. However, self-reported smothering behavior showed no significant reduction (OR: 0.66, 95% CI: 0.27-1.60). No side effects were reported. Watching an educational video on infant crying and the dangers of shaking and smothering within 1 week after delivery at maternity wards reduced self-reported shaking at 1 month of age.

Background: Child maltreatment induces significant health problems, both during childhood and into adulthood. To prevent child maltreatment, it is important to detect perinatal risk factors for earlier intervention. The aim of this study was to evaluate the perinatal risk factors associated with child maltreatment during pregnancy. Methods: A case-control study was conducted to compare perinatal data from the Maternal and Child Health Handbook between the case and control groups. Cases were collected from children registered in two Child Guidance Centers in Japan. The control group consisted of 3.5-year-old children in a city in Osaka Prefecture whose mothers responded to questionnaires containing information from the Maternal and Child Health Handbook. The association between perinatal factors and child maltreatment was assessed using multiple logistic regression analysis. Results: The data of 70 cases and 345 controls were collected. The following were found to be perinatal factors related to child maltreatment: teenage pregnancy (OR: 257.3, 95% CI: 17.3-3832.7), a mother aged 20-24 years (OR: 22.8, 95% CI: 4.4-117.8), a father who is older than the mother by 10 years or more (OR: 14.1, 95% CI: 2.1-94.8), an unmarried mother (OR: 15.7, 95% CI: 2.6-93.6), maternal mental disorder (OR: 48.9, 95% CI: 9.3-258.3), the first maternal prenatal visit being later than 20 weeks (OR: 132, 95% CI: 12.7-1384.7), little prenatal care (<10 visits) (OR: 21.4, 95% CI: 2.9-157.1), a low-birth-weight baby (OR: 5.1, 95% CI: 1.1-24.1), and congenital disease (OR: 7.9, 95% CI: 1.1-56.4). Conclusions: This study revealed that young mothers, fathers much older than mothers, unmarried mothers, and maternal mental disorder, mothers with late first visit or little perinatal care, and low-birth-weight babies and babies with congenital disease were associated with child maltreatment. These findings can be used to detect high-risk families for child maltreatment during or after pregnancy.
