Changes in dietary habits of the French population have been reported during the national lockdown that was enforced due to the COVID-19 pandemic. This study investigated whether perceived social eating norms were associated with the initiation and maintenance of dietary changes that took place as a result of lockdown. An online study collected information on (1) changes in consumption implemented during the lockdown and the maintenance of these changes, and (2) perceptions about changes in consumption implemented during lockdown by household members, relatives out of home, and the general population. The changes in consumption were classified as foods to increase or to decrease according to French national recommendations. The perception of changes to dietary habits by household members and relatives out of home was related to the changes made by individuals for each of the food categories (all < 0.05) but not to the perception of changes made the general population. Increased consumption of foods to increase was more likely to be maintained when there was a positive perception of the changes made by household members ( = 0.03). These results highlight the influence of the perception of social eating norms, especially by household members and relatives, on the implementation of dietary changes during lockdown and suggest that social eating norms can have a lasting influence.
据报道，在因新冠疫情实施全国封锁期间，法国民众的饮食习惯发生了变化。本研究调查了感知到的社会饮食规范是否与因封锁而发生的饮食变化的开始和维持有关。一项在线研究收集了以下信息：（1）封锁期间实施的消费变化以及这些变化的维持情况，（2）家庭成员、不在家的亲属以及一般人群对封锁期间实施的消费变化的看法。根据法国国家建议，将消费变化分为应增加或减少的食物。家庭成员和不在家的亲属对饮食习惯变化的看法与个人针对每种食物类别所做的变化相关（均P<0.05），但与对一般人群所做变化的看法无关。当对家庭成员所做的变化有积极看法时，增加应增加食物的消费量更有可能得以维持（P=0.03）。这些结果突出了社会饮食规范的感知，尤其是家庭成员和亲属的感知，对封锁期间饮食变化实施的影响，并表明社会饮食规范可能具有持久影响。
