摘要：After the COVID-19 lockdown, a ‘new normal’ was established, involving a hybrid lifestyle that combined face-to-face with virtual activity. We investigated, in a case-control study, the impact of the ‘new normal’ on daily sleep and eating routines, compared with pre-pandemic conditions. To do this, we propose using social and eating jet lag as markers of the regularity in daily routines. Additionally, we studied whether the ‘new normal’ had an impact on the body mass index (BMI), diet quality, and other health-related variables. This study included 71 subjects in the pre-pandemic group, and 68 in the ‘new normal’ group (20–30 years). For all participants, we evaluated social and eating jet lag, BMI, diet and sleep quality, eating behaviors, physical activity, and well-being. General linear models were used to compare outcome variables between pre-pandemic and ‘new normal’ groups. The results revealed that the ‘new normal’ was associated with greater regularity in daily sleep and eating routines (−0.7 h of social jet lag (95% CI: −1.0, −0.4), and −0.3 h of eating jet lag (95% CI: −0.5, −0.1)), longer sleep duration on weekdays (1.8 h (95% CI: 1.5, 2.2)), and lower sleep debt (−1.3 h (95% CI: −1.7, −0.9)). Regarding BMI and other health-related variables, we observed that these variables were similar between ‘new normal’ and pre-pandemic groups. These findings indicate that the ‘new normal’ had a positive impact on daily sleep and eating routines. Additionally, our results indicated that the ‘new normal’ offered college students a more sustainable lifestyle, which was associated with more hours of sleep during the week and lower sleep debt. This, in the long run, could have a positive impact on BMI and overall health.
