Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: To investigate the growth and development status for children of 1 \~ 3 years old in China, and to explore and analyze the influencing factors of infant growth. Mother's health status would also be investigated simultaneously.

Methods and analysis: This is a multicenter prospective cohort study. Participants were all from the Chinese Pregnant Women Cohort Study (CPWCS), which is a multicenter prospective cohort study we conducted before. In simple terms, pregnant women during the first trimester (5\~13 weeks' gestational age) were included from 25 July 2017 to 26 November 2018. Related information were collected by electronic self-administered questionnaire, including general information, environmental exposure assessment, physical activity assessment, dietary and nutritional assessment, depression assessment, sleep quality assessment and economic burden assessment. Subsequently, objective medical information, obstetric and neonatal outcomes were collected through hospital information system (HIS).

To further assess the mothers' and infants' health status, a new multicenter prospective cohort study, including more than 1000 participants of the CPWCS from 5 hospitals of 5 different provinces in China, will be conducted. Through the electronic self-administered questionnaire surveys and laboratory testing methods, information about infants' feeding, sleeping, defecating, oral health, early development and common allergic diseases will be collected. And we will also assess mothers' current health habits and status, such as sleeping, diet, anxiety, physical activity, and oral health. SAS statistical software will be used for data analysis.

Ethics and Dissemination Permission for the study was obtained from Chinese Academy of Medical Sciences and Peking Union Medical College. Ethics approval was obtained from the Ethics Review Committee of Department of Scientific Research, School of Basic Medicine, Peking Union Medical College, Beijing, China. The results will be published in peer-reviewed journals or disseminated through conference presentations.
