Peripartum mental health problems (such as anxiety and depression), affecting more than 20% of mothers, is one of the most common complications around childbirth and gradually have become global public health issues. However, little is known about the course of peripartum mental health problems and possible fluctuations, as well as related risk factors among Chinese women. In addition, there are no effective prediction and preventive strategies for postpartum depression. The Peripartum Mental Health Cohort Study in Guangzhou will collect the epidemiological, clinical information and biological specimens across pregnancy and childbirth to establish trajectory of peripartum mental health and identify the factors influencing the fluctuations and build a comprehensive prediction model of postpartum depression, as well as explore its adverse outcomes. This study would help to determine the timing of screening and target interventions to improve women's and their offspring's health.
The purpose of this study is to determine the incidence,development trajectory and risk factors of the main peripartum mental health problems as well as explore its adverse outcomes.
