Long-Term Impact of COVID-19 Pandemic in Sleep Quality and Lifestyle in Young Adults

Due to the evolution of COVID-19,restrictive measures were implemented. The quarantine resulted in significant changes in the social, economic, and psychological status of the population; however, its long-term effects have not yet been elucidated, especially in young adults. In the present study, people aged 18–25 years were studied, in relation to their sleeping, smoking, eating, and drinking habits and their physical activity before, during, and after the implementation of quarantine. We included 540 respondents (21.2 ± 2.3 years, 62.8% female). During quarantine, from 23 March to 4 May 2020, we observed an increase in sleep hours by 1.17 ± 1.98 h (p < 0.001), time of sleep arrival by 11.90 ± 30.41 min (p < 0.001), and number of daily meals by 0.66 ± 1.4 (p < 0.001). The subjects who consumed alcoholic beverages never or almost never had an upward change of 27.04%, and the time of daily exercise was reduced by 10.16 ± 48.68 min (p < 0.001). After quarantine, cigarettes per day increased by 1.14 ± 3.62 (p < 0.001) and the awakenings during night time increased by 0.37 ± 1.93 (p < 0.001). Our results suggest that the quarantine brought about significant changes in smoking, sleeping habits, physical activity, dietary habits, and the consumption of alcoholic beverages, some of which continue after its termination.
