Abstract

Abstract : Objective: The aim of this study was to examine the association between the amount, intensity, and pattern of steps·day −1 with weight loss. Methods: Participants ( N = 260; age = 42.8 ± 8.9 y; BMI = 32.8 ± 3.5 kg/m 2 ) completed an 18‐month weight‐loss intervention that included a calorie‐restricted diet and prescribed physical activity. Participants were categorized by 18‐month weight loss as weight gain (GAIN), weight loss of 0% to < 5% (WL < 5%), 5% to < 10% (WL < 10%), or ≥ 10% (WL ≥ 10%). Steps·day −1 were measured at 0, 6, 12, and 18 months and defined as total steps·day −1, total steps·day −1 of moderate‐to‐vigorous physical activity (MVPA) (≥3 metabolic equivalents) in bouts of ≥ 10 minutes (BOUT‐MVPA), MVPA in bouts of < 10 minutes (NON‐BOUT‐MVPA), or non‐MVPA steps·day −1 (NON‐MVPA). Results: There was a weight‐loss category by time interaction ( P < 0.0001) for total and BOUT‐MVPA steps·day −1 . The total steps·day −1 at 18 months were WL ≥ 10% = 9, 822 (95% CI: 9, 073‐10, 571), WL < 10% = 8, 612 (7, 613‐9, 610), WL < 5% = 7, 802 (6, 782‐8, 822), and GAIN = 7, 801 (6, 549‐9, 053). BOUT‐MVPA steps·day −1 at 18 months were WL ≥ 10% = 3, 482 (2, 982‐3, 981), WL < 10% = 1, 949 (1, 269‐2, 629), WL < 5% = 1, 735 (1, 045‐2, 426), and GAIN = 1, 075 (210‐1, 941). Participants were also categorized based on achieving ≥ 10% weight loss at either 6 or 18 months, and a similar pattern was observed. Conclusions: These findings show that 10, 000 steps·day −1, with approximately 3, 500 steps·day −1 performed as BOUT‐MVPA, are associated with enhanced weight loss in a behavioral intervention.
