Although insight in how adolescents' food intake is affected by the COVID-19 pandemic is critical, knowledge is limited. Hence, this longitudinal study ( = 691, = 14.30, = 0.62; 52.5% female) investigated changes in adolescents' unhealthy (sugar-sweetened beverages, sweet snacks, savoury snacks) and healthy (fruit and vegetables) food intake (in total, obtained from home, and from outside the home) from pre-pandemic (Spring 2019) to the first lockdown (Spring 2020) and to six months later (Fall 2020). Moreover, several moderating factors were assessed. Results showed that the intake of unhealthy and healthy food in total and obtained from outside the home decreased during the lockdown. Six months later, unhealthy food intake returned to pre-pandemic levels, while healthy food intake remained lower. COVID-19 stressful life events and maternal food intake further qualified these longer-term changes in intake of sugar-sweetened beverages and fruit and vegetables, respectively. Future work is warranted to elucidate longer-term COVID-19 effects on adolescents' food intake.
尽管了解青少年的食物摄入量如何受到新冠疫情的影响至关重要，但相关知识却很有限。因此，这项纵向研究（n = 691，M = 14.30，SD = 0.62；52.5%为女性）调查了青少年不健康（含糖饮料、甜零食、咸味零食）和健康（水果和蔬菜）食物摄入量（包括总体摄入量、在家中摄入的量以及在外摄入的量）从疫情前（2019年春季）到首次封锁（2020年春季）再到六个月后（2020年秋季）的变化。此外，还评估了几个调节因素。结果显示，在封锁期间，总体不健康和健康食物摄入量以及在外摄入的不健康和健康食物摄入量均有所下降。六个月后，不健康食物摄入量恢复到疫情前水平，而健康食物摄入量仍较低。新冠疫情压力性生活事件和母亲的食物摄入量分别进一步影响了含糖饮料和水果及蔬菜摄入量的这些长期变化。有必要开展进一步研究以阐明新冠疫情对青少年食物摄入量的长期影响。
