Regular physical activity is essential for asthma control in children, but it remains understudied within the context of COVID-19. Physical activity and sedentary time levels before and during the COVID-19 pandemic among children with asthma were documented and differences by characteristics were explored.
This was a cross-sectional self-administered online survey study of 5- to 17-year-old children with asthma from the United States between December 2020 and April 2021.
This study included 68 children with asthma. Although only 4.6% of the children were fully inactive before the pandemic, this number increased to 24.6% during the survey period ( < 0.001). Children spent significantly less time outdoors and more time in front of screens during the pandemic versus before ( < 0.001). The variety of activities in which children with asthma engaged in during the pandemic was lower than what they used to do prior to the COVID-19 crisis. Boys, Hispanic children, those of low-income households, and those not attending school in-person were significantly associated with less participation in physical activity during the pandemic. Ethnicity remained significantly associated after adjusting for multiple comparisons.
During the COVID-19 pandemic, children with asthma were less active and spent more time in front of screens and less time outdoors. Subgroup analyses revealed individual, parental, and organizational characteristics being associated with differential participation in physical activity, highlighting disparities in opportunities for children with asthma of different circumstances to remain active and healthy during the pandemic. Additional, more robust longitudinal studies are needed to confirm these results.
有规律的身体活动对儿童哮喘控制至关重要，但在 COVID-19 背景下，这方面的研究仍然不足。本研究记录了 COVID-19 大流行前和大流行期间哮喘儿童的身体活动和久坐时间水平，并探讨了其特征差异。
这是一项横断面自我管理的在线调查研究，对象为 2020 年 12 月至 2021 年 4 月期间来自美国的 5 至 17 岁哮喘儿童。
本研究共纳入 68 名哮喘儿童。尽管在大流行前只有 4.6%的儿童完全不活动，但这一数字在调查期间增加到 24.6%（<0.001）。与大流行前相比，儿童在大流行期间户外活动时间明显减少，屏幕前时间明显增加（<0.001）。哮喘儿童在大流行期间参与的活动种类比 COVID-19 危机前减少。男孩、西班牙裔儿童、低收入家庭儿童和不上学的儿童在大流行期间身体活动参与度显著降低。在进行多次比较调整后，种族仍与身体活动参与度显著相关。
在 COVID-19 大流行期间，哮喘儿童的活动量减少，在屏幕前的时间增加，户外活动时间减少。亚组分析显示，个人、父母和组织特征与身体活动参与度的差异相关，突出了不同情况下哮喘儿童在大流行期间保持活跃和健康的机会存在差异。需要进行更多的、更有力的纵向研究来证实这些结果。
