Nezu, PhD, Erik Lehman, MS, Cheryl Dellasega, PhD Background: Few studies have examined the weight-control practices that promote weight loss and weight-loss maintenance in the same sample. Purpose: To examine whether the weight control practices associated with weight loss differ from those associated with weight-loss maintenance. Methods: Cross-sectional survey of a random sample of 1165 U.S. adults. The adjusted associations of the use of 36 weight-control practices in the past week with success in weight loss (10% lost in the past year) and success in weight-loss maintenance (10% lost and maintained for 1 year) were examined. Results: Of the 36 practices, only 8 (22%) were associated with both weight loss and weight-loss maintenance. Overall, there was poor agreement (kappa=0.22) between the practices associated with weight loss and/or weight-loss maintenance. For example, those who reported more often following a consistent exercise routine or eating plenty of low-fat sources of protein were 1.97 (95% CI=1.33, 2.94) and 1.76 (95% CI=1.25, 2.50) times more likely, respectively, to report weight-loss mainte- nance but not weight loss. Alternatively, those who reported more often doing different kinds of exercises or planning meals ahead of time were 2.56 (95% CI=1.44, 4.55) and 1.68 (95% CI=1.03, 2.74) times more likely, respectively, to report weight loss but not weight-loss maintenance. Conclusions: Successful weight loss and weight-loss maintenance may require two different sets of practices. Designing interventions with this premise may inform the design of more effective weight-loss maintenance interventions.
