The proposed overall research aims to establish feasibility of delivering an individually-tailored, behavioral intervention to manage gestational weight gain [GWG] that adapts to the unique needs and challenges of overweight/obese pregnant women [OW/OB-PW] and will utilize control systems engineering to optimize this intervention; in other words, make this intervention manage GWG in OW/OB-PW as effectively and efficiently as possible.

You will be randomized into an intervention or attention control group from ~8 weeks gestation to ~37 weeks gestation with a BMI of 25-45 (>40 with physician consent). You will have 1 pre-intervention session that explains the study procedures and to get you ready for the study. Here you will also complete various measures of demographics, behavioral surveys, etc. Over the course of the study, you will weigh yourself each day, wear an activity monitor and complete various surveys. If you are randomized to the intervention group, you may have healthy eating demonstrations and/or physical activity sessions each week. You will have 1 post-intervention session where you will return your devices, complete a 30-60 minute interview and complete the last of the surveys.
