Obesity

Faculty in the SPHHP are engaged in work dedicated
to understanding how complex factors may affect
childhood obesity including policy, economics, and environments. Projects are guiding interventions that
will help fight the growing global epidemic.

Causes and Interventions for Childhood Obesity: Innovative Systems Analysis

Youfa Wang, MD, MS, PhD and Hong Xue, PhD, MS

Department: Epidemiology and Environmental Health

Objectives: Using integrated conceptual framework, innovative statistical analysis approaches, and rich data from multiple sources we will study how complex factors may affect childhood obesity and test potential intervention options.

Multilevel Systems-oriented Childhood Obesity Study In China

Youfa Wang, MD, MS, PhD and Hong Xue, PhD, MS

Location: China
Department: Epidemiology and Environmental Health

Objectives: To use a systems-oriented conceptual framework, unique rich longitudinal data collected in China from large cohorts, and novel systems analysis to study the interplay, impact, and feedback loops of the built, social, economic, environmental and policy factors and their changes on individual children and their families' decisions, eating, physical activity, and adiposity outcomes. We will also study why some individuals /families may respond differently to the environments and how they may affect their environments. China offers an unprecedented opportunity for systems-oriented pediatric obesity research considering its large population size, area and regional contextual variation; the rapid economic growth and many social- environmental transformations over the past 2-3 decades including dramatic changes in its food systems and food environment. Findings will have many important policy implications for other countries as well. 

Evaluation of Childhood Obesity Prevention Programs

Youfa Wang, MD, MS, PhD and Hong Xue, PhD, MS

Location: China
Department: Epidemiology and Environmental Health

Objectives: A systematic review and meta analysis to assess the effects of intervention programs conducted in high-income countries that directed at children and/or their families (including school-based and non-school based programs, as well as those related to policies and the built environment) on childhood obesity and related conditions, and children's related knowledge, belief and attitude. The project will help guide future interventions and policies in the U.S., and other countries fighting the growing global epidemic.
