Lockdown due to COVID-19 pandemic has forced a decrease in physical activity (PA), an increase in sedentary behavior (SB) and a possibly worsening of fat accumulation in already obese subjects. The aim of this study was to investigate how social restriction may have contributed to weight changes in adolescents with obesity. Secondary aim was to evaluate possible parameters influencing weight changes.
Parameters of 51 obese adolescents were compared between two visits: within 2 months before 8 March, start of lockdown, and within 40 days after the end of it.
Mean weight gain during lockdown was 2.8 ± 3.7 kg (p < 0.001). Weight increase was higher in males than in females (3.8 ± 3.4 kg vs 1.2 ± 3.7 kg, p = 0.02). The hours dedicated to SB increased (+2.9 ± 2.8 h/day; p < 0.001) while the hours of PA decreased (-1.0 ± 1.6 h/week; p < 0.001). Males spent more hours in SB than females (+3.8 ± 2.7 h/day vs +1.5 ± 2.5 h/day; p = 0.003). There were minor changes in diet during lockdown. The most significant variables influencing both delta BMI and waist/height ratio increase were hours devoted to SB during lockdown and differences in mild and moderate PA before and after lockdown.
Obese adolescents showed a worsening of obesity during lockdown, with males mainly affected, mainly due to a reduced mild PA and increased hours spent in SB.
由于 COVID-19 大流行而实施的封锁措施迫使人们减少体力活动（PA），增加久坐行为（SB），并且已经肥胖的人群脂肪堆积可能恶化。本研究旨在探讨社交限制如何导致肥胖青少年体重发生变化。次要目的是评估可能影响体重变化的参数。
在两次就诊期间比较了 51 名肥胖青少年的参数：在 3 月 8 日封锁开始前的 2 个月内和封锁结束后的 40 天内。
封锁期间的平均体重增加了 2.8 ± 3.7kg（p<0.001）。男性的体重增加高于女性（3.8 ± 3.4kg 比 1.2 ± 3.7kg，p=0.02）。SB 时间增加（+2.9 ± 2.8h/天；p<0.001），而 PA 时间减少（-1.0 ± 1.6h/周；p<0.001）。男性比女性在 SB 上花费更多的时间（+3.8 ± 2.7h/天比 +1.5 ± 2.5h/天；p=0.003）。封锁期间饮食有轻微变化。影响 deltaBMI 和腰围/身高比增加的最重要变量是封锁期间用于 SB 的时间以及封锁前后轻度和中度 PA 的差异。
肥胖青少年在封锁期间肥胖状况恶化，主要受男性影响，主要是由于轻度 PA 减少和 SB 时间增加所致。
