The COVID-19 pandemic resulted in substantial lifestyle changes. No US study has identified predictors of perceived dietary healthfulness changes during the pandemic period. This study included analyses of lifestyle and dietary healthfulness changes using 958 survey responses from US primary household food purchasers. Information was collected related to demographics, COVID-19-related household changes, and health-related habits before and during the pandemic. Binary logistic regression identified predictors of perceived increase in dietary healthfulness during the pandemic period. Overall, 59.8%, 16.4%, and 23.4% of participants reported that their eating habits likely changed, may have changed, and likely did not change, respectively. Of the participants whose dietary habits likely or may have changed, 64.1%, 16.8%, and 19% reported healthier, neither healthier nor less healthy, and less healthy eating habits, respectively. COVID-19-related income loss, more meals consumed with household members in front of the television, an increase in food advertisement exposure, increased perceived stress, and better perceived current health were significant predictors of a perceived increase in dietary healthfulness. Overall, dietary habits were perceived to become healthier during the pandemic. The predictors of perceived improvement in dietary healthfulness were surprising and indicate the need for further study of these factors in crisis and noncrisis situations.
COVID-19 大流行导致生活方式发生了重大变化。没有美国的研究确定了在大流行期间感知饮食健康变化的预测因素。这项研究包括使用来自美国主要家庭食品购买者的 958 份调查回复进行的生活方式和饮食健康变化分析。收集了与人口统计学、与 COVID-19 相关的家庭变化以及大流行前后健康相关习惯相关的信息。二元逻辑回归确定了大流行期间感知饮食健康增加的预测因素。总体而言，分别有 59.8%、16.4%和 23.4%的参与者报告说他们的饮食习惯可能发生了变化、可能发生了变化或可能没有发生变化。在饮食习惯可能或可能发生变化的参与者中，分别有 64.1%、16.8%和 19%报告说饮食习惯更健康、既不健康也不更健康和更不健康。与 COVID-19 相关的收入损失、与家庭成员一起在电视机前吃更多的餐、增加食物广告曝光率、增加的感知压力以及更好的当前健康感知是感知饮食健康增加的显著预测因素。总体而言，在大流行期间，饮食习惯被认为变得更健康。感知饮食健康改善的预测因素令人惊讶，表明需要进一步研究这些因素在危机和非危机情况下的作用。
