During the coronavirus disease 2019 (COVID-19) pandemic, the Australian state of Victoria (in particular, its capital, Melbourne) experienced some of the longest lockdowns in the world.
This repeated cross-sectional study examined changes between March to June 2019 (pre-pandemic) and April to August 2022 (6 to 11 months following pandemic-related lockdowns) in overweight and obesity prevalence, physical activity, sedentary behaviour, sleep, diet quality, and health-related quality of life (HRQoL) among primary school children in north-east Victoria, Australia.
Height and weight were measured for Grade 2, 4, and 6 students in 2019 (3889 children) and 2022 (1816 children). Grade 4 and 6 students self-reported on their movement behaviours, diet quality, and HRQoL.
Participation declined among schools (2019:56%, 2022:34%) and students (2019:87%, 2022:75%). Compared to children in 2019, children in 2022 had a higher prevalence of overweight and obesity; were less likely to have met guidelines for moderate-to-vigorous physical activity, recreational screen time, and vegetable consumption; had higher intakes of takeaway food, energy-dense nutrient-poor snacks, and sugar-sweetened beverages; and had lower HRQoL.
Children's health-related behaviours and outcomes seemed not to have returned to pre-pandemic levels 6 to 11 months after the final lockdowns lifted for their communities. Continued monitoring and interventions targeting the drivers of childhood obesity are urgently needed.
在2019年冠状病毒病（COVID-19）大流行期间，澳大利亚维多利亚州（尤其是其首府墨尔本）经历了世界上一些持续时间最长的封锁。
这项重复横断面研究调查了2019年3月至6月（大流行前）与2022年4月至8月（与大流行相关的封锁解除后的6至11个月）之间，澳大利亚维多利亚州东北部小学生的超重和肥胖患病率、身体活动、久坐行为、睡眠、饮食质量以及健康相关生活质量（HRQoL）的变化。
测量了2019年（3889名儿童）和2022年（1816名儿童）二、四、六年级学生的身高和体重。四、六年级学生自行报告了他们的运动行为、饮食质量和健康相关生活质量。
学校参与率下降（2019年：56%，2022年：34%），学生参与率也下降（2019年：87%，2022年：75%）。与2019年的儿童相比，2022年的儿童超重和肥胖患病率更高；达到中度至剧烈身体活动、娱乐屏幕时间和蔬菜消费指南的可能性更低；外卖食品、能量密集但营养匮乏的零食和含糖饮料的摄入量更高；健康相关生活质量更低。
在社区最后一次封锁解除6至11个月后，儿童与健康相关的行为和结果似乎尚未恢复到大流行前的水平。迫切需要持续监测并针对儿童肥胖的驱动因素进行干预。
