OBJECTIVE
The Chinese government decisively imposed nationwide confinement in response to the COVID-19 outbreak. This study aimed to evaluate the impact of the COVID-19 pandemic on the progression of obesity in children and adolescents in Changshu, China.
METHODS
Based on the Health Promotion Program for Children and Adolescents (HPPCA), which is a prospective cross-sectional and school-based study, BMI assessed in seven consecutive years (2014 to 2020) among children and adolescents aged 6 to 17 years in Changshu city was extracted. The standardized BMI z scores (zBMI) and prevalence of obesity between 2020 (after COVID-19 home confinement) and the previous 6 years were compared among age-specific subgroups and between sexes.
RESULTS
The mean number of participants per year was 29,648. The overall mean zBMI drastically increased from 0.29 in 2019 to 0.45 in 2020, resulting in a rise of 0.16 (95% CI: 0.14-0.18); the prevalence of obesity substantially elevated to 12.77% in 2020 (versus 10.38% in 2017), with an acceleration of 2.39% (95% CI: 1.88%-2.90%). Of note, these increases were more likely to be observed in boys and those 6 to 11 years old.
CONCLUSIONS
The COVID-19 pandemic seemed to exacerbate the obesity epidemic among pediatric populations in Changshu, China.
目的
中国政府果断对新冠肺炎疫情实施全国性封控。本研究旨在评估新冠肺炎疫情对中国常熟市儿童和青少年肥胖进展的影响。
方法
基于儿童和青少年健康促进计划（HPPCA），这是一项前瞻性的连续的基于学校的研究，提取了 2014 年至 2020 年 6 至 17 岁儿童和青少年连续 7 年的 BMI（体重指数）评估数据。比较了 2020 年（新冠肺炎居家隔离后）与前 6 年的年龄特异性亚组和性别之间的标准化 BMI z 分数（zBMI）和肥胖患病率。
结果
每年的平均参与者人数为 29648 人。总体而言，zBMI 的平均值从 2019 年的 0.29 急剧上升到 2020 年的 0.45，上升了 0.16（95%CI：0.14-0.18）；肥胖患病率从 2017 年的 10.38%显著上升到 2020 年的 12.77%，增长率为 2.39%（95%CI：1.88%-2.90%）。值得注意的是，这些增长更可能发生在男孩和 6 至 11 岁的儿童中。
结论
新冠肺炎疫情似乎加剧了中国常熟市儿童人群中的肥胖流行。
