In this study, we investigated self-weighing frequency (SWF) among adults during the COVID-19 pandemic and retrospectively (6 months) before the pandemic, and whether SWF was associated with changes in health-related behaviors. United States adults (N = 1607) completed a health-related questionnaire during COVID-19 and associated shelter-in-place. We categorized respondents into 4 groups of SWF at the time of the pandemic: "Never," "< 1x a week," "1x a week," or "> 1x a week." The proportion of adults never weighing increased during the pandemic (15% to 25%), whereas the proportion of those weighing < 1x week went down (41% to 29%). Higher SWF was significantly associated with changes in energy expenditure including increased total physical activity (PA), lower likelihood of decreases in vigorous, moderate, and walking PA, and a lower likelihood of sitting more. More frequent self-weighing also was associated statistically with lower likelihood of keeping unhealthy eating behaviors the same. Conversely, there was no significant difference in changes in alcohol, caffeine, takeout, fruit or vegetable consumption, and television viewing among SWF groups. SWF decreased during the pandemic in the lower 2 SWF categories. Higher SWF was associated with fewer negative changes in health behaviors, especially related to PA.
在这项研究中，我们调查了 COVID-19 大流行期间和大流行前 6 个月成年人的自我称重频率（SWF），并探讨了 SWF 是否与健康相关行为的变化有关。美国成年人（N=1607）在 COVID-19 期间和相关的就地避难期间完成了一项健康相关的问卷。我们将受访者在大流行期间分为 4 组 SWF：“从不”、“<1 次/周”、“1 次/周”或“>1 次/周”。在大流行期间，从不称重的成年人比例增加（从 15%到 25%），而每周称重<1 次的比例下降（从 41%到 29%）。更高的 SWF 与能量消耗的变化显著相关，包括总体力活动（PA）增加、剧烈、中等和步行 PA 减少的可能性降低，以及久坐的可能性降低。更频繁的自我称重也与保持不健康饮食行为不变的可能性降低统计学上相关。相反，在 SWF 组之间，酒精、咖啡因、外卖、水果或蔬菜摄入以及看电视等行为的变化没有显著差异。在较低的 2 个 SWF 类别中，SWF 在大流行期间减少。更高的 SWF 与更少的健康行为负面变化相关，尤其是与 PA 相关。
