Routine Life-Course Health Records in Infancy Predict Being Overweight in Childhood and Adolescence
Background/Objectives : Being overweight in childhood is a strong predictor of later obesity and related health disorders, underscoring the importance of the early identification of at-risk children. The aim of this study was to develop a prediction model for being overweight across childhood and adolescence using routine life-course health records available up to 18-23 months of age. Methods : We analyzed 1581 participants from the Tohoku Medica…
Paternal bonding failure and depression at 1 month postpartum are associated with neurodevelopmental delay in 4‐year‐old children
We aimed to determine the association between paternal bonding failure and depression in the postpartum period and children's neurodevelopment, as an Adjunct Study of the Japan Environment and Children's Study (JECS), a prospective cohort study. We evaluated the association between the Japanese version of the Mother‐to‐Infant Bonding Scale (MIBS) / Edinburgh Postnatal Depression Scale (EPDS) scores for fathers and the Ages and Stages Questionnair…
Trajectories of paternal depression symptoms from 1 to 6 months postpartum and associated factors
This prospective birth‐cohort study aimed to determine the factors associated with new‐onset paternal depression symptoms from 1 to 6 months postpartum in Japan. Paternal depression symptoms were evaluated using the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS‐J) at 1 to 6 months postpartum. The definition of paternal depression symptoms was EPDS‐J ≥8 in this study. Multivariate regression analysis was performed to analyze t…
Association between being Overweight in Young Childhood and during School Age and Puberty
To examine whether body type at birth, body weight, and obesity in early childhood are associated with overweight/obesity during school age and puberty. Data from maternal and child health handbooks, baby health checkup information, and school physical examination information of participants at birth and three-generation cohort studies were linked. Association between body type and body weight at different time intervals (at birth and at 1.5, 3.5…
Comprehensive evaluation of machine learning algorithms for predicting sleep–wake conditions and differentiating between the wake conditions before and after sleep during pregnancy based on heart rate…
In the test for predicting three types of sleep-wake conditions, most of the algorithms, except for Naïve Bayes, showed higher areas under the curve (AUCs; 0.82-0.88) and accuracy (0.78-0.81). The test using four types of sleep-wake conditions with differentiation between the wake conditions before and after sleep also resulted in successful prediction by the gated recurrent unit with the highest AUC (0.86) and accuracy (0.79). Among the nine fea…
Associations of Education and Income with Secondhand Smoke Exposure Among Non-smoking Pregnant Women in Japan
Associations between sugar-sweetened beverages before and during pregnancy and offspring overweight/obesity in Japanese women
Objective: The association between high sugar-sweetened beverages (SSB) intake during pregnancy and offspring overweight/obesity has been reported only from Western countries. The objective of this study was to examine the association between SSB intake before and during pregnancy and offspring overweight/obesity among Japanese women. Design: Japanese prospective birth cohort study. Setting: We analysed mother–offspring pairs who participated in …
Heart Rate Information-Based Machine Learning Prediction of Emotions Among Pregnant Women
In this study, the extent to which different emotions of pregnant women can be predicted based on heart rate-relevant information as indicators of autonomic nervous system functioning was explored using various machine learning algorithms. Nine heart rate-relevant autonomic system indicators, including the coefficient of variation R-R interval (CVRR), standard deviation of all NN intervals (SDNN), and square root of the mean squared differences o…
Validity of Diagnostic Algorithms for Inflammatory Bowel Disease in Japanese Hospital Claims Data
Inflammatory bowel disease (IBD) diagnoses are increasing in Japan. Some patients have symptoms that are difficult to control, and further research on IBD is needed. Claims databases, which have a large sample size, can be useful for IBD research. However, it is unclear whether the International Classification of Diseases, Tenth Revision (ICD-10) codes alone can correctly identify IBD. We aimed to develop algorithms to identify IBD in claims data…
Validity of Administrative Data for Identifying Birth-Related Outcomes with the End Date of Pregnancy in a Japanese University Hospital
This study aimed to develop and validate claims-based algorithms for identifying live birth, fetal death, and cesarean section by utilizing administrative data from a university hospital in Japan. We included women who visited the Department of Obstetrics at a university hospital in 2018. The diagnosis, medical procedures, and medication data were used to identify potential cases of live birth, fetal death, and cesarean section. By reviewing elec…
Similarities in cardiometabolic risk factors among random male-female pairs
In this study, few similarities in cardiometabolic risk factors were noted among the random male-female pairs. As spouse pairs may share environmental factors, intervention strategies targeting lifestyle habits and preventing lifestyle-related diseases may be effective
Associations of education and work status with alcohol use and cessation among pregnant women in Japan
Women with higher education were more likely to consume alcohol in early pregnancy and to cease alcohol use between early and middle pregnancy, especially working women. Working women were more likely to consume alcohol throughout pregnancy. Working women with lower education were less likely to cease alcohol use, whereas working women with higher education were more likely to cease alcohol use between early and middle pregnancy
