This study examined effects of COVID-19 restrictions in early 2020 on movement (physical activity, sedentary behavior and sleep) and healthy eating behaviors in families with 0-12-year-old children in western Sydney, Australia. A total of 1,371 parents completed an online survey about changes in children's and families' food intake and movement behaviors. There was an increase in sedentary screen use by children (4.18/5.00) and families (3.91/5.00) and a slight increase in reported physical activity (3.56/5.00), amount of food consumed (3.58/5.00) and meals and snacks eaten (3.69/5.00) during the height of the COVID-19 restrictions compared to before. There was little change in reported sleep (3.17/5.00). Lower socioeconomic families were disproportionately affected, with greater increases in unhealthy eating (t = 2.739, = 0.06), lower levels of improvement in physical activity, such as walking and cycling (t = -7.521, < 0.001) and outdoor activity (t = 5.415, < 0.001), and higher increases in family sedentary behavior (t = 2.313, = 0.021). Therefore, even short periods of restrictions can result in detrimental health behavior changes. Such changes could become entrenched leading to increased risk of lifestyle diseases. Programmatic and policy strategies should be geared toward promoting healthy movement behaviors, focusing on families of lower socioeconomic status to ensure the pandemic does not widen an existing gap.
本研究考察了 2020 年初 COVID-19 限制措施对澳大利亚西悉尼 0-12 岁儿童家庭中儿童的运动（身体活动、久坐行为和睡眠）和健康饮食行为的影响。共有 1371 名家长完成了一项关于儿童和家庭食物摄入和运动行为变化的在线调查。儿童（4.18/5.00）和家庭（3.91/5.00）久坐屏幕使用时间增加，报告的身体活动（3.56/5.00）、食物摄入量（3.58/5.00）和用餐和零食（3.69/5.00）略有增加，与 COVID-19 限制措施实施前相比。报告的睡眠（3.17/5.00）几乎没有变化。社会经济地位较低的家庭受到的影响不成比例，不健康饮食（t = 2.739， = 0.06）增加更多，身体活动（如步行和骑自行车）（t = -7.521， < 0.001）和户外活动（t = 5.415， < 0.001）改善水平较低，家庭久坐行为（t = 2.313， = 0.021）增加更多。因此，即使是短期的限制也会导致健康行为的不利变化。这种变化可能会变得根深蒂固，从而增加生活方式疾病的风险。计划和政策战略应侧重于促进健康的运动行为，关注社会经济地位较低的家庭，以确保大流行不会扩大现有的差距。
