Chapter 5, Problem 56P

Officials in the State Health Department are considering using the active intervention in the general population of women with GDM. However, they expect that 80% of the women who are offered the intervention will actually comply with the intervention and are expected to have a weight gain distribution similar to the active group. The remaining 20% of women will lose interest and are expected to have a weight gain distribution similar to the control group.

What % of the GDM women in the program will be expected to be no more than 2 lbs. above their pre-pregnancy weight?

The program will be implemented if at least 50% of the GDM women in the program are no more than 2 lbs. above their pre-pregnancy weight at 12 months postpartum.
