Impact of Diet and Exercise Activity on Pregnancy Outcomes (IDEA)

January 6, 2026 updated by: Garry Shen, University of Manitoba

Impact of a Community-based Obesity and Diabetes Prevention Program on Pregnant Outcomes in Pregnant Women

The general goal of the present study is to assess the impact of a community-based exercise and dietary intervention in pregnant women living in urban areas during and after their pregnancy on the reduction of the risks of both diabetes and obesity in mothers and their offspring.

We hypothesize that a community-based lifestyle intervention program during and after gestation may improve pregnancy outcomes in terms of reducing the risk of developing obesity or type 2 DM in mothers and their children.
