Research Methods and Procedures:This study was a lifetime cost-use analysis from a societal perspective, using a first-order Monte Carlo simulation. Strategies included routine primary care and varying combinations of diet, exercise, behavior modification, and/or pharmacotherapy. Primary data were collected to assess program costs and obesity-related quality of life. Other data were obtained from clinical trials, population-based surveys, and other published literature. This was a simulated cohort of healthy 35-year-old overweight and obese women in the United States. Results: For overweight and obese women, a three-component intervention of diet, exercise, and behavior modification cost $12,600 per quality-adjusted life year gained compared with routine care. All other strategies were either less effective and more costly or less effective and less costeffective compared with the next best alternative. Results were most influenced by obesity-related effects on quality of life and the probabilities of weight loss maintenance. Discussion: A multidisciplinary weight loss program consisting of diet, exercise, and behavior modification provides good value for money, but more research is required to confirm the impacts of such programs on quality of life and the likelihood of long-term weight loss maintenance.

ROUX, LARISSA, AND CAM DONALDSON. Economics and obesity: costing the problem or evaluating solutions? Obes Res. 2004;12:173-179. There is no doubt that obesity is a major public health problem. However, what is the contribution of economics to solving it? In this report, we make the case that the role of economics is not in measuring the economic burden of obesity, through so-called cost-of-illness studies. Such studies merely confirm that obesity is a serious societal issue; adding a monetary figure to this does not add much. The economic foundations of such estimates can also be questioned, thus lessening their policy relevance. The real value of economics in the arena of obesity care is in evaluating, through formal economic evaluation, the use of our scarce health care resources in different strategies to prevent and treat obesity.

ROUX, LARISSA, CHRISTINA UBACH, CAM DONALDSON, AND MANDY RYAN. Valuing the benefits of weight loss programs: an application of the discrete choice experiment. Obes Res. 2004;12:1342-1351. Objective: Obesity is a leading health threat. Determination of optimal therapies for long-term weight loss remains a challenge. Evidence suggests that successful weight loss depends on the compliance of weight loss program participants with their weight loss efforts. Despite this, little is known regarding the attributes influencing such compliance. The purpose of this study was to assess, using a discrete choice experiment (DCE), the relative importance of weight loss program attributes to its participants and to express these preferences in terms of their willingness to pay for them. Research Methods: A DCE survey explored the following weight loss program attributes in a sample of 165 overweight adults enrolled in community weight loss programs: cost, travel time required to attend, extent of physician involvement (e.g., none, monthly, every 2 weeks), components (e.g., diet, exercise, behavior change) emphasized, and focus (e.g., group, individual). The rate at which participants were willing to trade among attributes and the willingness to pay for different configurations of combined attributes were estimated using regression modeling.Results: All attributes investigated appeared to be statistically significant. The most important unit change was "program components emphasized" (e.g., moving from diet only to diet and exercise). Discussion: The majority of participants were willing to pay for weight loss programs that reflected their preferences. The DCE tool was useful in quantifying and understanding individual preferences in obesity management and provided information that could help to maximize the efficiency of existing weight loss programs or the design of new programs.
