Cheung Yin BinAs part of an international research collaboration, Professor Cheung Yin Bun of the Centre for Quantitative Medicine (CQM) at Duke-NUS Medical School, developed a set of gestational weight gain (GWG) charts and published them in the prestigious American Journal of Clinical Nutrition [1]. Using prospectively collected weight measurements of pregnant women from 14 to 41 weeks of gestation and statistical methodology for longitudinal data analysis, the team developed not only a conventional, cross-sectional GWG chart but also longitudinal GWG charts, which takes prior weight status into account. That is, the (longitudinal) GWG chart for a woman is calibrated according to her weight in the previous visit, as opposed to using one chart for all women or one chart for a woman at all time.
