  1. aPercentage weight change above target range = change in weight in kilograms during the pregnancy divided by the top of the target range in kilograms (defined by the IOM guidelines) multiplied by 100. A value above 100% would indicate that on average the change in weight during pregnancy was greater than the expected target range
