Associations between low birth weight, childhood adversity, and natural disaster with delay discounting among children.

According to the Developmental Origins of Health and Disease (DOHaD) hypothesis, low-birthweight (LBW) infants are programmed to seek additional resources as compensation for early deprivation. However, no study has yet explored this in the context of delay discounting (DD), which refers to the tendency to prefer smaller, immediate rewards over larger, delayed ones. Both prenatal factors, such as LBW, and postnatal factors, including adverse childhood experiences (ACEs) and exposure to natural disasters, may influence DD.

Heat Stress and Placental Abruption: A Space-Time Stratified Case-Crossover Study.

Objective: To examine whether heat stress, measured by wet bulb globe temperature (WBGT), a comprehensive heat stress index is associated with placental abruption within 7 days.

Design: A space-time-stratified case-crossover design.

Setting: All 11 regions in Japan during the warm season (June-September) from 2011 to 2020.

Drops in Atmospheric Pressure and Subsequent Fluctuations in Daily Delivery Volume: A Case-Crossover Study.

Background: Fluctuations in daily delivery volume impact obstetricians' workload and maternal-fetal complications. While sudden drops in atmospheric pressure (e.g.

Household Income, Maternal Allostatic Load During Pregnancy, and Offspring With Autism Spectrum Disorders.

Relative maternal poverty is a suggested social determinant of autism spectrum disorders (ASDs) in offspring; however, this association may be confounded by the maternal broader autism phenotype (BAP). The biological mechanisms underlying this association are largely understudied. We examined the association between household income during pregnancy and ASDs in offspring, adjusting for confounders including maternal BAP, and explored whether maternal chronic stress, measured by allostatic load (AL) during pregnancy, mediates this association.

Years of education mediate the association between adverse childhood experiences and unintended pregnancy: A population-based study in Japan.

Background: Adverse childhood experiences (ACEs) have been associated with unintended pregnancies, including mistimed pregnancies (MP) and unwanted pregnancies (UWP). However, it remains unknown which cluster of ACEs (i.e.

Association between gestational weight gain and behavioral problems of the offspring aged 6-7 years: A population-based study in Japan.

Objective: To identify the optimal gestational weight gain (GWG) thresholds for behavioral problems and prosocial behavior in 6- to 7-year-old children.

Methods: A retrospective cohort study was conducted using data from the Adachi Child Health Impact of Living Difficulty study, including all first-graders in public schools in Adachi, Tokyo, in 2017, 2019, and 2021 (n = 11 048, response rate = 80.1%).

Ambient temperature and preterm birth: A case-crossover study.

Objective: To investigate the association between ambient temperature and preterm birth (PTB) and to estimate the population attributable fraction (PAF) of PTBs due to low and high temperatures.

Design: Time-stratified case-crossover design.

Setting: Japan (46 prefectures, excluding Okinawa), 2011-2020.

Association of severe maternal morbidity with bonding impairment and self-harm ideation: A multicenter prospective cohort study.

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).

Association of maternal pre-pregnancy body mass index with resilience and prosociality of the offspring aged 6-7 years old: a population-based cohort study in Japan.

The association between maternal pre-pregnancy obesity and child behavior problems has been widely researched, leaving a gap in understanding the positive aspects of children's mental health. The present study aimed to investigate the association between maternal pre-pregnancy body mass index (BMI) and resilience and prosociality among 6-7 year-old children in Japan. A retrospective cohort study was conducted using data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, a population-based study in 2017 and 2019 including all first-grade students in public schools in Adachi, Tokyo, Japan (n = 7328, response rate = 84.

Relationship trajectories of pregnant women with their parents and postpartum depression: A hospital-based prospective cohort study in Japan.

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.

Association of Paternity Leave with Impaired Father-Infant Bonding: Findings from a Nationwide Online Survey in Japan.

Although the number of fathers taking childcare leave is increasing, the impact of paternity leave on father-infant bonding remains to be fully investigated. This study aimed to assess the association between paternity leave and father-infant bonding among fathers with children under two years old. A cross-sectional study was performed using data from the Japan COVID-19 and Society Internet Survey study, a nationwide online survey conducted between July and August 2021 (N = 1194).

The relationship between postpartum depression and social support during the COVID-19 pandemic: A cross-sectional study.

Aim: This study aims to examine the prevalence of postpartum depression and its relationship with social support adjusted for self-perceived impact of COVID-19 in parturient women admitted to a perinatal medical center in Japan.

Methods: This cross-sectional study included 513 women who underwent a 1-month postpartum checkup between August 3 and November 27, 2020. Postpartum depression was measured using the Edinburgh Postnatal Depression Scale.

Changes in the Ultrasonographical Appearance of Intertwin-Dividing Membrane of Monochorionic Diamniotic Twin Pregnancy.

Ultrasound determination of chorionicity in the first trimester has a high accuracy, but it is associated with some pitfalls. This report presents changes in ultrasound findings during a monochorionic pregnancy with chorionic membrane folding (CMF). The patient was a 32-year-old woman, gravida 2 para 0.
