Rena Wing is well known for her research on behavioral treatment of obesity and particularly its application to type II diabetes. She has published over 200 peer-reviewed articles on these topics. Currently, she is the principal investigator on the Diabetes Prevention Program and has developed the lifestyle intervention being used in all 27 centers in that study. In addition, she is principal investigator at The Miriam Hospital site for a 15-center trial entitled, Study of Health Outcomes of Weight Loss and serves as chair of this multi-site study. Wing is a member of the council for National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and serves on the NIDDK Task Force on the Prevention and Treatment of Obesity.
Research DescriptionRena Wing's research focuses on behavioral treatment of obesity and addresses the following questions:
1. What are the health benefits of modest weight loss?
She was responsible for developing and implementing the lifestyle intervention that was used in the Diabetes Prevention Program (DPP). DPP was a randomized, controlled trial testing whether lifestyle intervention or metformin (a diabetes medication) could delay the onset of type 2 diabetes. More than 3,000 overweight patients with impaired glucose tolerance, recruited at 27 centers nationwide, participated and were randomly assigned to placebo, metformin, or intensive lifestyle intervention. The DPP showed that modest weight losses (14 pounds on average) reduced the risk of developing diabetes by 58% compared to placebo, whereas metformin reduced risk by only 31%. This study is the most compelling evidence to date of the health benefits of weight loss.
Currently, Dr. Wing is examining whether weight loss improves urinary incontinence in over 330 overweight women with this disorder.
Most importantly, she is currently chair of Look AHEAD, an ongoing study funded by National Institutes of Health (NIH) testing whether weight loss reduces cardiovascular morbidity or mortality in over 5,000 overweight individuals with type 2 diabetes. Participants are recruited from 16 centers across the United States with a center at the Miriam Hospital. Although weight loss is known to have positive short-term (1 year) effects on diabetes, this study is the first to examine the long-term (12 years) health impact.
2. How can we improve behavioral treatment of obesity?
Rena Wing has been studying ways to improve behavioral approaches to obesity for many years. She had approached this topic by conducting randomized clinical trials comparing different strategies that might be included in behavioral programs. She has shown, for example, that higher exercise goals and structured approaches to diet can improve weight loss outcomes. She has conducted studies evaluating the role of involving overweight spouses, using financial incentives, encouraging taking breaks from dieting, and creating intra-group and inter-group competitions. Current studies are investigating the effects of reducing variety in the diet and examining the effect of modifying the home environment.
Recently, this research has expanded to include studies to increase the dissemination of behavioral techniques by using the internet. Randomized trials have evaluated various approaches using human e-mail counseling or automated counseling.
3. Is it possible to prevent weight gain and subsequent obesity?
A third focus has been on key time periods where prevention of weight gain might be most effective. These periods have included childhood, the period surrounding pregnancy, and the menopausal transition. Working with Leonard Epstein, Rena Wing did a number of clinical trials of behavioral treatments for obese children aged 8-12 and their overweight parent(s). Current approaches target younger children (ages 4-8) and adolescents.
Rena Wing participated in a single center clinical trial of weight loss during menopause and showed that the lifestyle intervention successfully reduced weight gain and the increases in LDL-cholesterol that are typically seen in middle-aged women.
4. What are the characteristics of successful weight loss maintainers?
A key issue in the treatment of obesity is the maintenance of weight loss. Her research incorporates several different approaches to this problem. First, she is a founder of the National Weight Control Registry, a registry of over 5,000 people who have lost over 30 pounds (mean = 70 pounds) and kept it off at least one year (mean = 5.7 years). Self-reported data from these successful weight losers has been used to provide information about the behaviors associated with long-term maintenance of weight loss.
In addition, she has shown that it is possible to teach the strategies of successful weight losers to others and thereby improve their maintenance of weight loss. In a project called STOP Regain, she has found that a self-regulation intervention delivered via internet or face-to-face can reduce the risk of weight regain.
A current study by Rena Wing compares successful weight losers with normal weight controls and obese controls on both behavioral measures and brain responses to food cues. The question being addressed is whether successful weight losers who have reduced to normal weight now respond to food cues as always-normal weight controls, or whether they continue to respond as if obese.
