Maternal & Pediatric Obesity

Our research focuses on the genetic, environmental, social and behavioral contributors to obesity.

We are re-engineering care to improve screening, tailoring preventive counseling and using systems design to direct families to multi-disciplinary, treatment programs when indicated. We are training primary care providers and support staff to use motivational interviewing skills, utilizing tele-health, apps and electronic health records, and coordinating care between clinics and community agencies and schools to help families identify and act on solutions that make healthy, active choices easier.

The goals of our research include:

  • Intergenerational prevention of obesity and related chronic diseases for families 
  • Integrated framework for childhood obesity prevention and treatment across spheres of influence
  • Multi-level interventions that address biological, behavioral, environmental, economic, and policy factors
  • Implementation and dissemination research
  • Pragmatic trials and longitudinal studies
  • Patient-centered clinical decision support
  • Behavioral and environmental correlates of obesity, adiposity, fitness and metabolic-related diseases

WEE Baby Care Study

The goal of the pragmatic trial is to build and evaluate a Chronic Care Model for delivering consistent personalized messages to coordinate care across multiple settings- health care clinics and Women, Infants and Children (WIC) clinics- to support mothers and children and their related health outcomes.  Our solution-oriented approach aims to coordinate care to optimize parenting education for the primary prevention of early pediatric obesity.

PREVENT

This project integrates an evidence-based behavior and home environment risk assessment into pediatric well child visits for children aged 2- to 9-years of age, as a component of universal prevention screening. The Family Nutrition and Physical Activity (FNPA) risk assessment is collected prior to scheduled visits as patient-reported data and instantly documented in the child’s electronic health record as clinical decision support.  Parents also indicate attitude toward discussion topics to help inform preventive counseling to prevent and reduce childhood obesity. This quality improvement initiative has been implemented as standard of care in pediatric primary care.  Longitudinal analyses are underway to evaluate behavior, environment, and weight outcomes associated with this annual, brief intervention.

Grow with WIC

The project aims to improve retention of WIC clients until age 5 years in Pennsylvania.  Program enhancements regarding messaging and customer service were informed by clients and incorporated into local clinics.  An observational, case-matched controlled study design is being used to evaluate retention (primary outcome) until age 5 years as sell as participation, awareness, knowledge, satisfaction, barriers and beliefs associated with the WIC Program.

Teaching Appropriate Gestational Weight Gain (TAGG)

This project aims to improve obstetrical care by managing gestational weight gain among high risk gravida to decrease maternal and fetal complications and to reduce economic costs associated with excessive gestational weight in women with obesity. A randomized controlled trial is underway to assess the difference in proportion of patients that do not gain above the Institute of Medicine’s Gestational Weight Gain guidelines when exposed to nutrition consultation and regular telephone coaching calls vs. standard of care. Additional outcomes include pregnancy complications, maternal and neonatal intensive care unit admissions as well as psychosocial and behavioral outcomes. 

Study Name: Addressing High Gestational Weight Gain to Improve Patient-Experience, Reduce Intensive Care Unit Admissions, and Lower Costs

Funding Support: Geisinger Health Plan

Early Healthy Lifestyles

This project integrates an evidence-informed behavior and home environment risk assessment into pediatric well child visits for children aged 0-26 months for children with elevated weight for length. Parents complete the brief risk assessment prior to scheduled well child visits and results are instantly recorded in the child’s electronic health record with clinic decision support. Analyses are underway to evaluate behavior, environment, and weight outcomes associated with this annual, brief intervention. The original risk assessment fielded in 2013-2015 was updated with evidence-based findings and incorporated into the WEE Baby Care Study since 2016.
