Summary

This pilot and feasibility study will enroll newly pregnant women at risk for high sedentary behavior (SED) and elevated APO risk (n=53) and will randomize them to either a SED reduction intervention or control. Research aims include to: 1) demonstrate our ability to decrease SED and increase standing and light activity in pregnant women; 2) evaluate feasibility; and 3) gather preliminary effects on clinical outcomes including APOs, cardiometabolic risk factors, well-being, and fetal outcomes.
