“Obesity is the number-one health problem in the United States because it negatively affects our population’s health more than any other condition,” said Kaiser Permanente Washington Health Research Institute Senior Investigator David Arterburn, MD, MPH. Kaiser Permanente Washington researchers are doing practical research to learn how doctors, patients, families, employers, and policymakers can best work together to prevent and treat obesity.
“We’re focusing on three ways to halt the obesity epidemic,” said Senior Investigator Dori Rosenberg, PhD, MPH. “We’re helping to change obesity-promoting environments, bringing evidence-based prevention and treatment programs into health care systems, and helping people develop lifelong healthy diet and activity habits.”
Kaiser Permanente Washington obesity research areas include:
“Obesity is caused by many factors, so at Kaiser Permanente Washington, we’re working on many levels,” said Paula Lozano, MD, MPH, a senior investigator and Kaiser Permanente Washington’s assistant medical director for preventive care. “We’re improving health care to help people who are obese now. But since obesity is a societal problem, we’re also studying how to change our homes and workplaces and neighborhoods to create more healthy environments.”
