{"doi":"10.1002/oby.70082","title":"Association Between Wake‐Time Movement Behaviors and Weight Loss Maintenance","abstract":"OBJECTIVE: We examined whether wake-time movement composition was associated with weight loss maintenance among individuals who experienced clinically meaningful weight loss (> 5% of initial weight) using compositional data analysis. METHODS: This was a secondary analysis from a behavioral weight loss maintenance intervention on weight regain over 12 months following clinically meaningful 3-month weight loss. Body weight was assessed at baseline, after weight loss (3 months), and at end of intervention (15 months). Wake-time behaviors (sedentary time [ST], light physical activity [LPA], and moderate-to-vigorous PA [MVPA]) were assessed at two time points during the maintenance intervention using accelerometry. Compositional data analysis was used to examine associations between wake-time movement composition and weight regain (kg). RESULTS: Among 153 individuals (80.4% female, 69.9% White), wake-time movement composition was related to weight regain (p = 0.001). MVPA was negatively associated with weight regain (p's < 0.05). Reallocating 10 min/day from ST or LPA to MVPA was associated with less weight regain (ST: -0.32 kg [-0.53, -0.12]; LPA: -0.37 kg [-0.59, -0.15]). Individuals who maintained clinically meaningful weight loss and those who did not differed in wake-time movement composition, driven by MVPA (36.1 vs. 24.3 min/day). CONCLUSIONS: The composition of wake-time behaviors, specifically MVPA, reduces weight regain after clinically meaningful weight loss in a behavioral weight loss maintenance intervention.
