循证在线行为减肥（BWL）治疗的目标是饮食，身体活动和行为技能训练的组合。虽然减肥的结果是有据可查的，但对身体活动的变化知之甚少。这项研究检查了在一个完全自动化的在线BWL程序中，客观测量的身体活动在能量消耗谱中的变化。超重或肥胖的成年人（n= 63）完成了为期12周的在线BWL计划。参与者佩戴加速度计7天，并在治疗前和治疗后在诊所测量体重。在治疗后，平均每日中度至剧烈体力活动增加约4分钟（SE= 1.59，p = 0.01）。轻度体力活动或久坐时间无统计学显著变化（p> 0.05）。尽管总体上中度至剧烈体力活动的变化很小，但较大的增加与较大的体重减轻相关（r=-0.28，p = 0.02），治疗后平均为基线体重的6.1%。虽然取得了重要的减肥成果，但在线计划可能无法在身体活动方面产生临床相关的改善，这可能会使减肥维持处于危险之中。
Evidence-based online behavioral weight loss (BWL) treatment targets a combination of diet, physical activity, and behavioral skills training. While weight loss outcomes are well documented, little is known about changes in physical activity. This study examined changes in objectively measured physical activity across the energy expenditure spectrum during a fully automated, online BWL program. Adults with overweight or obesity (n= 63) completed a 12-week, online BWL program. Participants wore an accelerometer for 7 days and body weight was measured in-clinic at pre- and post-treatment. At post-treatment, mean daily moderate-to-vigorous physical activity increased by about 4 min (SE= 1.59,p= 0.01). There were no statistically significant changes in light physical activity or time spent sedentary (p’s > 0.05). Despite only minimal changes in moderate-to-vigorous physical activity overall, larger increases correlated with greater weight loss (r= − 0.28,p= 0.02), which averaged 6.1% of baseline weight at post-treatment. Though achieving important weight loss outcomes, online programs may fail to produce clinically relevant improvements in physical activity, which can put weight loss maintenance at risk.
