Effects of COVID-19 lockdown on the dietary habits and lifestyle in a population in southern Spain: a cross-sectional questionnaire

Background/Objective Few studies have assessed the effect of lockdown on physical activity and eating behaviours in a population from the Autonomous Community of Andalusia in southern Spain. The aim of our study was to describe the effect of COVID-19 pandemic home lockdown on eating habits and lifestyle in the Andalusian population. Subjects/Methods A cross-sectional observational study was carried out on a population from southern Spain, Andalusian population. An online questionnaire was shared through social networks and snowball sampling. A total of 1140 people filled in the questionnaire. The questionnaire consisted of 34 items classified into three sections: sociodemographic data, work and leisure activities and questions on food consumption. Each item offered pre- and post-lockdown information. Results The participants were classified into three age groups: 18–35, 36–65 and over 65. Statistically significant differences were found between the three groups, with the younger age group undergoing greater changes, increasing their physical activity and consumption of fresh food, and decreasing both their consumption of fast food at home and alcohol intake. Conclusions These findings suggest that, in the current social and health crisis, the citizens of southern Spain have become aware of the importance of maintaining an appropriate lifestyle to remain healthy, particularly the younger population with less well-consolidated habits.
