The spread of COVID-19 and the associated stay-at-home orders and shutdowns of gyms and fitness centers have drastically influenced health behaviors leading to widespread reductions in physical activity (PA). The recent Call to Action from the American College of Sports Medicine has promoted "innovative strategies to promote PA during the COVID-19 pandemic." We aimed to identify individual-level factors that protected against declines in PA levels amid the COVID-19 restrictions.
We used the Pennington Biomedical COVID-19 Health Behaviors Survey for our analyses and used mixed-effect linear and generalized linear models to estimate the effects of individual-level factors on changes in PA levels during the COVID-19 restrictions.
Participants (n = 4376) provided information on PA behaviors before and during the COVID-19 shutdown. Overall, PA levels declined by a mean ± SD of 112 ± 1460 MET·min·wk-1 during the COVID-19 shutdown; however, changes in PA were heterogeneous, with 55% of the participants reporting increases in or maintenance of PA during that time. Several social and demographic factors were significantly related to declines in PA, including high prepandemic PA levels, living alone (difference = 118 MET·min·wk-1), low household income (difference between the highest and the lowest income group = 363 MET·min·wk-1), COVID-19-related changes in income (difference = 110 MET·min·wk-1), and loss of employment (difference = 168 MET·min·wk-1). The substitution of prepandemic gym attendance with the purchase and use of home exercise equipment or exercise through virtual fitness platforms promoted increases in PA during the COVID-19 shutdown.
While promoting PA through the COVID-19 pandemic, it is important to consider demographic factors, which greatly influence health behaviors and implementation of, and access to, replacement behaviors. The promotion of such strategies could help maintain PA levels during potential future stay-at-home orders.
COVID-19 的传播以及随之而来的居家令和健身房及健身中心的关闭,极大地影响了健康行为,导致体力活动(PA)广泛减少。美国运动医学学院最近发出的“行动呼吁”提倡“在 COVID-19 大流行期间促进 PA 的创新策略”。我们旨在确定个人层面的因素,以防止在 COVID-19 限制期间 PA 水平下降。
我们使用彭宁顿生物医学 COVID-19 健康行为调查来进行分析,并使用混合效应线性和广义线性模型来估计个人层面因素对 COVID-19 限制期间 PA 水平变化的影响。
参与者(n=4376)提供了 COVID-19 关闭前后 PA 行为的信息。总体而言,PA 水平在 COVID-19 关闭期间平均下降了 112±1460 MET·min·wk-1;然而,PA 的变化是不均匀的,有 55%的参与者报告在此期间 PA 增加或维持不变。一些社会和人口因素与 PA 下降显著相关,包括高流行前 PA 水平、独居(差异=118 MET·min·wk-1)、低收入家庭(最高和最低收入组之间的差异=363 MET·min·wk-1)、COVID-19 相关收入变化(差异=110 MET·min·wk-1)和失业(差异=168 MET·min·wk-1)。用购买和使用家庭锻炼设备或通过虚拟健身平台来代替流行前的健身房锻炼,促进了 COVID-19 关闭期间 PA 的增加。
在 COVID-19 大流行期间促进 PA 时,重要的是要考虑到人口因素,这些因素极大地影响了健康行为以及替代行为的实施和获得。推广这些策略可以帮助维持未来可能的居家令期间的 PA 水平。
