A real-time data monitoring and management system for Thailand’s first national sizing survey

Following the success of SizeUK and SizeUSA, Thailand had embarked on its first National Sizing Survey (SizeThailand), to construct a major anthropometrics database of over 12,500 people. Using a 3D body scanning technology that takes less than 10 seconds per scan to capture a highly accurate 3D body image, from which hundreds of body measurements can be extracted, the survey was able to be conducted rapidly and accurately. As it was not possible to measure everyone in the country, a statistically significant sample of subjects needed to be recruited. Throughout the 14-month data collection period in 13 locations around the country, information on the subjects such as age, region of residence, socio-economic data, as well as size and body mass index data had to be continuously monitored in real-time so that those eligible would be chosen to take part. This paper describes a complete Web-based data management system which was implemented to dynamically monitor the 5-stage subject recruitment process and perform integrity checking on the data being collected for the SizeThailand database.
