Technical Abstract: This study examined weight loss among Mexican American students in a weight management program. A total of 358 participants completed a 12-week intervention that incorporated four program components: nutrition education (NE), physical activity (PA), sedentary behavior (SB), and a snacking intervention (SI). NE, PA, and SB were all consistent with USDA dietary guidelines. The SI consisted of providing students with peanuts or peanut butter, a nutrient dense snack intended to promote satiety. Self-report of adherence to program components was collected at 6 months. Students were classified as having successful weight outcomes if they maintained or decreased their weight at 6 months. Participants' weight decreased by an average of 1.5 percentile points (t=9.4, p<.001). High levels of adherence to all program components except PA were found to increase the likelihood of having successful weight outcomes (Odds ratios: 2.8-4.0; ps<.001). When accounting for variance between variables, SB accounted for the most variance in having a successful weight outcome, followed by NE adherence. The SI was the final predictive variable in the model. With the exception of PA, higher levels of adherence were shown to be predictive of successful weight outcomes for Mexican American students. Each of these components appeared to independently impact weight outcomes.
