The aim of this study was to evaluate the impact of coronavirus disease 2019 (COVID-19) lockdown on body mass index (BMI) z-score of adolescents treated for obesity, and to assess the correlation between BMI z-score changes and lifestyle variables.
This cross-sectional study recruited 66 participants aged 11-18 years with overweight or obesity who attended our obesity clinics before and after the lockdown. We assessed demographic and anthropometric characteristics as well as lifestyle variables.
The mean BMI z-score of the participants was stable during this period (p = 0.233). Balanced diet, snacking, and sweet beverage consumption improved in about half of the participants. Having at least one parent at home was associated with a significantly more balanced diet (p = 0.008) and an increase in family activities (p = 0.015). Physical activities decreased (51.5%) and screen time increased for most of the adolescents (86.4%). The BMI z-score decreased significantly when three or more lifestyle habits improved (p<0.001).
This study showed that BMI z-scores were stable for a majority of adolescents treated for obesity during the COVID19 lockdown, along with positive and negative changes on weight-related lifestyle habits. This extraordinary period may have created opportunities for lifestyle modification and has emphasized the importance of family support in the management of obesity in adolescents.
本研究旨在评估 2019 年冠状病毒病（COVID-19）封锁对肥胖青少年治疗的体重指数（BMI）Z 评分的影响，并评估 BMI Z 评分变化与生活方式变量之间的相关性。
这项横断面研究招募了 66 名年龄在 11-18 岁之间的超重或肥胖青少年，他们在封锁前后参加了我们的肥胖症诊所。我们评估了人口统计学和人体测量特征以及生活方式变量。
在此期间，参与者的平均 BMI Z 评分保持稳定（p=0.233）。大约一半的参与者的均衡饮食、零食和含糖饮料摄入量有所改善。至少有一位家长在家与饮食更均衡（p=0.008）和家庭活动增加（p=0.015）显著相关。大多数青少年的体育活动减少（51.5%），屏幕时间增加（86.4%）。当三种或更多生活习惯改善时，BMI Z 评分显著下降（p<0.001）。
这项研究表明，在 COVID19 封锁期间，大多数接受肥胖治疗的青少年的 BMI Z 评分保持稳定，同时与与体重相关的生活方式习惯也出现了积极和消极的变化。这个特殊时期可能为生活方式的改变创造了机会，并强调了家庭支持在青少年肥胖管理中的重要性。
