Purpose:
The National Weight Control Registry (NWCR) was founded in 1993 and is a collaborative venture between Dr. James Hill of the University of Colorado and Dr. Rena Wing of Brown University and University of Pittsburgh. The NWCR is a longitudinal prospective study of individuals 18 years and older, who have successfully maintained a 30 pound weight loss for a minimum of 1 year. Currently, the registry includes approximately 4,500 individuals.
NWCR Fast Facts:
- Successful weight losers report making substantial changes in eating and exercise habits to lose weight and maintain their losses.
- The average registrant has lost approximately 60 pounds and has maintained that loss for roughly 5 years.
- Two-thirds of these successful weight losers were overweight as children and 60% report a family history of obesity.
- Approximately 50% of participants lost weight on their own without any type of formal program or help.
- Walking is the most frequently cited physical activity performed by NWCR members.
- There is no cost to join the registry and names are always kept confidential.
If you are interested in joining the registry, please call 1-800-606-NWCR (6927).
