Brief Summary:
The purpose is 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 \[OW/OBPW\] and will utilize control systems engineering to optimize this intervention; in other words, make this intervention manage GWG in OW/OBPW as effectively and efficiently as possible.
Detailed Description:
The research proposed here will establish the dosage of components needed to impact GWG and develop an efficient (optimized) intervention to effectively manage GWG in OW/OBPW before a randomized controlled trial (RCT) can be implemented. The aims of the proposed research are: to establish feasibility of delivering an individually-tailored behavioral intervention for managing GWG in OW/OBPW. Two studies will be conducted to establish feasibility. Study 1 will examine viability of delivering dosages/sequencing of components (education, goal-setting, self-monitoring, HE/PA), GWG/HE/PA self-monitoring using e-health technology mechanisms, and data collection by delivering varied dosages to OW/OBPW over a brief, 4-week period followed by focus groups to evaluate user acceptability. The investigators will then make necessary revisions to the intervention. Study 2 will pilot test intervention delivery with decision rules for when/how to adapt dosages for an individual and randomization/retention/data collection procedures with treatment and control groups in a new cohort of OW/OBPW. Also, the investigators aim to use feasibility data collected from Aim 1 and control systems engineering to build a model that characterizes the effects of energy balance and planned/self-regulatory behaviors on GWG over time and use this model to develop an optimized intervention. The investigators will identify a dynamical model from feasibility data collected in Aim 1 that considers how changes in GWG responds to changes in energy intake, PA, and planned/self-regulatory behaviors. Model predictive control (a decision-making method from control systems engineering) will inform how the dosage adaptations are decided. The investigators will then identify a customized intervention plan for each woman based on her levels of energy intake, PA, planned/self-regulatory behaviors and the extent to which she is meeting GWG goals over pregnancy. This will lead to final program modifications and result in an individually-tailored, optimized intervention. The investigators will test the efficacy of this optimized intervention for managing GWG in OW/OBPW in a future RCT. This innovative research will develop an individually-tailored, optimized intervention that effectively and efficiently manages GWG in OW/OBPW and that will eventually be available to all pregnant women (via e-health technology) to improve the health of mothers and infants and impact the etiology of obesity and cardiovascular disease at a critical time in the life cycle.
