The purpose of this study is to learn the impact stress may have on weight management and
emotional eating.
emotional eating.
The investigator's long-term goal is to contribute to the development of empirically-based,
clinically-useful weight loss and weight maintenance interventions. The objective in this
application is to obtain proof of feasibility for a weight loss and maintenance intervention
that addresses the underlying issue of stress, as an effective approach to long-term weight
loss and maintenance. The central hypothesis for this application is that the weight
management intervention utilizing stress management skills will produce weight loss and
significant improvements in stress and metabolic syndrome biomarkers at 10 and 20 weeks
follow-up. This hypothesis was formulated based upon data showing that stress is associated
with increased risk of obesity and a few small studies that have shown this method of stress
management can produce long-term weight loss and maintenance and decreased depression and
stress. The rationale for the proposed studies is that proof of feasibility for such an
intervention will enable subsequent definitive studies at the R01 level. If, however, the
investigators were to unexpectedly disprove the concept, such a result would also be
valuable because it would lead the investigators to shift focus and redistribute resources
accordingly. To test the central hypothesis, and thereby accomplish the objective for this
application, the following specific aims will be pursued:
1. Compare a stress management based program to a standard behavioral weight loss program
for weight loss and cost-effectiveness. The approach will involve two different
intervention groups. Group 1(control) will receive a standard behavioral weight loss
program. Group 2 will receive a stress management based intervention built on research
in neuroscience and principles of the attachment theory.
2. Determine secondary outcomes from both interventions, including stress as measured by
salivary cortisol and telomere length; depression, disordered eating patterns, dietary
intake, and physical activity. It is hypothesized that Group 2 will show greater
improvements in all secondary outcomes at both 10 and 20 weeks follow-up than Group 1.
3. Establish proof of concept that decreases in stress variables are associated with
improvement in weight and stress-related psychological variables.
At the completion of this study, the investigators expect to determine the type of
intervention that produces the greatest weight loss in a community sample at 10 and 20 weeks
follow-up. The investigators will also have determined what impact the two interventions
have on secondary outcomes, including stress as measured by salivary cortisol and telomere
length; depression, disordered eating patterns, dietary intake, and physical activity.
