Abstract
Due to the pandemic situation caused by the COVID-19 infection, some governments have implemented house confinement measures. The objective of our study is to learn the dietary patterns, consumption, and physical activity of the Spanish population before and during the period of confinement by COVID-19. A cross-sectional descriptive study based on a questionnaire during May 2020, coinciding with the period of confinement and the step forward into Phase 1, is carried out. During confinement, the adherence to the Mediterranean Diet increases (8.0% versus 4.7%; p < 0.001). No socio-demographic variables show statistical significance (p < 0.05) regarding good adherence to the Mediterranean Diet (MD) before and during confinement. During confinement, consumption of homemade baking shows a higher increase (0.28% versus 4.60%; p = 0.004). During confinement, the number of subjects that practice exercise decreases (29.4% versus 28.8%; p = 0.004), as well as the time spent exercising (more than an hour, 26.6% versus 14.7%, p = 0.001). Mediterranean Diet adherence slightly increases during confinement, although consumption of 'unhealthy' food also increases. Moreover, the number of subjects that practice physical activity, as well as the time spent on it weekly, decreases.
