Tohoku Medical Megabank Project Three-Generation Cohort Study

10-year efforts and perinatal outcomes

Abstract

The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study (TMM BirThree Cohort Study) included pregnant women, fetuses, and their families and relatives from 2013 to 2017. Currently, we are conducting follow-up surveys through questionnaires, blood and urine tests, disease onset surveys, and the collection of school health check-up information. Based on medical records from pregnancy to a month after delivery, the prevalence of hypertensive disorders of pregnancy, gestational diabetes, premature birth, low birth weight, and small for gestational age were described and characterized according to parity, pre-pregnancy body mass index, and multiple pregnancies. The TMM BirThree Cohort Study promotes collaborative research and expands the use of valuable information for researchers. We aim to continue generating useful findings that would benefit the participants and local people.
