Obesity treatment-associated transfer of exercise-related self-regulation to eating-related self-regulation changes in women.

Abstract

Obesity in the United States has risen to 42 percent of its adult population and is similarly problematic in many other countries. Although the U.S. government has provided education on healthy eating and the need to exercise regularly, behavioral obesity treatments have largely failed to sustain reductions in weight. Self-regulation, and the incorporation of exercise for its psychological impacts on eating, has sometimes been targeted. While there has been sporadic investigation into the carry-over of exercise-related self-regulation to eating-related self-regulation, the present aim is to further inquiry in that area to inform future treatment content for improved effects. Women enrolled in community-based obesity treatments with either a self-regulation (n = 106) or education (n = 54) focus were assessed on changes in exercise- and eating-related self-regulation, negative mood, completed exercise, and weight. Improvements were significantly greater in the self-regulation-focused group. After controlling for initial change in eating-related self-regulation, change in that measure from Month 3 to 6 was significantly predicted by change in exercise-related self-regulation during the initial 3 treatment months. This suggested a carry-over effect. A stronger predictive relationship was associated with the self-regulation-focused treatment. In further analyses, paths from changes in exercise→negative mood→self-regulation of both exercise and eating were significant. Increase in eating-related self-regulation was significantly associated with weight loss over 6, 12, and 24 months. The self-regulation-focused group had stronger relationships, again. Findings suggested utility in targeting exercise-related self-regulation to impact later change in eating-related self-regulation, and the use of exercise-associated mood improvement to bolster participants' self-regulation capabilities.
