The coronavirus disease pandemic is predicted to have adverse health effects on children and adolescents who are overweight or obese due to restricted school activity and stay-at-home orders. The purpose of this observational study was to determine the factors associated with weight gain in children and adolescents with overweight and obesity during coronavirus disease 2019 (COVID-19) lockdown.
Ninety-seven participants (sex- and age-specific body mass index (BMI) ≥ 85th percentile) were included. A baseline examination was conducted pre-COVID-19 (August 2019 to January 2020), and re-examination was performed post-lockdown (June to September 2020) and the results were compared. Correlation and regression analyses were conducted to investigate the association among changes in cardiometabolic markers and lifestyle behaviors with changes in BMI z-score.
During the COVID-19 pandemic, an increase in BMI z-score (2.56 [2.01-2.94] to 2.62 [2.03-3.18]) was noticed in children and adolescents with obesity. Changes in cardiometabolic markers including liver enzymes, triglycerides ( = 0.398), leptin ( = 0.578), and adiponectin ( = -0.326), as well as muscular strength ( = -0.212), were correlated with the increase in BMI z-score. According to a multivariate regression analysis, changes in sedentary time (B = 0.016; 95% confidence interval [CI], 0.001-0.032) and fast-food consumption (B = 0.067; 95% CI, 0.013-0.122) were the lifestyle variables associated with BMI z-score increase.
Changes in lifestyle behaviors including fast-food consumption and sedentary time during the COVID-19 pandemic may be associated with weight gain. In order to prevent health-related risks in children and adolescents with obesity during the pandemic, it is important to maintain the level of physical activity and healthy dietary habits.
由于学校活动受限和居家令的实施，预计冠状病毒病大流行将对超重或肥胖的儿童和青少年的健康产生不利影响。本观察性研究的目的是确定与 2019 年冠状病毒病（COVID-19）封锁期间超重和肥胖儿童和青少年体重增加相关的因素。
纳入 97 名参与者（性别和年龄特异性体重指数（BMI）≥第 85 百分位）。在 COVID-19 之前进行基线检查（2019 年 8 月至 2020 年 1 月），并在封锁后进行重新检查（2020 年 6 月至 9 月），比较结果。进行相关和回归分析，以调查代谢标志物和生活方式行为变化与 BMI z 评分变化之间的关联。
在 COVID-19 大流行期间，肥胖儿童和青少年的 BMI z 评分（2.56 [2.01-2.94] 至 2.62 [2.03-3.18]）增加。代谢标志物的变化，包括肝酶、甘油三酯（=0.398）、瘦素（=0.578）和脂联素（=0.326）以及肌肉力量（=0.212），与 BMI z 评分的增加相关。根据多元回归分析，久坐时间的变化（B=0.016；95%置信区间[CI]，0.001-0.032）和快餐消费（B=0.067；95%CI，0.013-0.122）是与 BMI z 评分增加相关的生活方式变量。
COVID-19 大流行期间，包括快餐消费和久坐时间在内的生活方式行为的变化可能与体重增加有关。为了防止大流行期间肥胖儿童和青少年的健康相关风险，保持身体活动水平和健康饮食习惯非常重要。
