The GI Baby 3 database contains numerical data and supplementary information relating to a randomised controlled trial study that measures the influence of maternal diet on the the birthweight of the infant. The study aims to identify risk factors associated with gestational diabetes, high birth weight and child obesity.
Data was collected at the Royal Prince Alfred (RPA) Hospital in Sydney, NSW, from a randomised sample of 120 women, recruited between 12 and 18 weeks pregnancy. The women were put on two diets, and data was collected at four-weekly intervals until the baby was born. At birth, data relating to the delivery method, gestational age, birth weight and body fat percentage of the infant was collected.
The resulting dataset consists of tables of information in spreadsheet (MS Excel) format, including clinical and demographic data about each participant, including height, weight, age, ethnicity, dietary factors, and numerical data from survey responses. The dataset also contains clinical data about each infant, including the results of glucose tolerance tests, cord blood glucose tests, delivery methods, gestational age, birth weight and body fat percentage of the infant. The dataset is delivered via a custom Filemaker Database, which is used to manage the spreadsheets and associated metadata, and track appointments and tests undertaken by each of the participants throughout the project.
The project is expected to be completed in 2016. Once the project is complete, the dataset will be de-identified, and may be able to be shared, subject to the appropriate level of human ethics clearance.
