Based on evidence that gravida mental illness is one risk factor for child maltreatment, we implemented an intervention study in which public health nurses visited the homes of high-risk pregnant women living in Adachi City. Domestic violence during pregnancy was also investigated as one major risk factor for maternal mental health (see details on the JST project page).
In another study, pregnancy records are linked with the medical checkups of neonatal to 3-year-old children to investigate the association between gravida mental health and child health outcomes, including development and maltreatment.
In order to determine the long-term impact of disaster-related trauma on child mental health, we are conducting a cohort study of children living in Iwate, Miyagi, and Fukushima prefecture who experienced the Great East Japan Earthquake. For comparison, children in Mie prefecture are also participating. Data collection includes time preference, heart rate variability and blood pressure as well as recordings from FaceReader, which assesses emotion from facial expressions.
Other research includes collecting data on suspected autism spectrum disorder, behavior problems, prosocial behavior, resilience, self-esteem, and the perceived happiness of children.
