On Wednesday 18/03/2020 Belgium was placed in lockdown in order to curb the spread of COVID-19. Lockdown can lead to loneliness, boredom, anger, anxiety and depression, which in turn have an influence on food choices and physical activity (PA). This study aims to map the adjustments in food choices and PA by Flemish adults during lockdown.
Chi square tests were performed to investigate the relationship between adjustments in food choices, PA and demographic variables.
A total of 1.129 respondents filled in the online questionnaire, aged between 18 and 81 years. The healthiest food choices were made by respondents living alone during lockdown, whilst people cohabiting with others increased their PA significantly. Moreover, the dietary adjustments of adults living with children evolved more favourably to healthier choices then those cohousing with other adults. However, respondents living with other adults showed a more favourable pattern regarding adjustments in PA. The strongest increase in sedentary behaviour was observed in students.
This study shows the impact of lockdown on both PA and food choices, where healthier adjustments were observed in PA and respondents were prone to consume unhealthier food.
为了遏制 COVID-19 的传播，比利时于 2020 年 3 月 18 日星期三实行封锁。封锁可能导致孤独、无聊、愤怒、焦虑和抑郁，进而影响食物选择和身体活动（PA）。本研究旨在描绘封锁期间弗拉芒成年人食物选择和 PA 的调整情况。
使用卡方检验来调查食物选择、PA 和人口统计学变量之间的关系。
共有 1129 名年龄在 18 至 81 岁之间的受访者填写了在线问卷。在封锁期间独居的受访者做出了最健康的食物选择，而与他人同居的人则显著增加了 PA。此外，与孩子同住的成年人的饮食调整更有利于更健康的选择，而与其他成年人同住的成年人则不然。然而，与其他成年人同住的受访者在 PA 的调整方面表现出更有利的模式。在学生中观察到久坐行为的最强增加。
本研究表明封锁对 PA 和食物选择都有影响，PA 方面的调整更为健康，而受访者则倾向于食用不健康的食物。
