Abstract
Although health‐enhancing weight reductions are associated with behavioural treatments initially, a trajectory towards full regain typically begins within 6–9 months. Women with obesity (body mass index = 30–40 kg m−2) who lost at least 3% of their baseline weight within two trials of a new cognitive‐behavioural treatment incorporating physical activity prior to changes in eating behaviours, and either regained ≥50% of that weight over 2 years (Regain group, n=32) or continued to lose weight (ContinuedLoss group, n = 34), were assessed from months 6 to 24 on changes in weight‐loss behaviours and psychosocial predictors of those behaviours derived from established behavioural theories. For the Regain group, significant decreases in physical activity and fruit/vegetable intake during months 12–24, from both months 6 to 24 and 12 to 24 in eating‐ and physical activity‐related self‐regulation and from months 6 to 24 in eating‐related self‐efficacy (i.e. feelings of ability), were found. No significant behavioural or psychosocial changes were found over those times in the ContinuedLoss group. Changes in self‐regulation and self‐efficacy completely mediated the relationship between changes in fruit/vegetable intake and group (Regain vs. ContinuedLoss) (McFadden’s R 2 = 0.19 and 0.20, respectively), with self‐regulation independently contributing to the explained variance. Changes over both months 6–24 and 12–24 in self‐regulation significantly mediated the relationship between changes in physical activity and group membership (McFadden's R 2 = 0.24 and 0.27, respectively). Findings suggested that approximately 6 months after treatment initiation would be a suitable time to intervene with some bolstering methods, while approximately 12 months post‐initiation would be most applicable for others.
