Healthy habits in children. Before, during and after confinement due to COVID-19 Hbitos saludables en ni?os. Antes, durante y despus del confinamiento por COVID-19

Adequate physical activity (PA) engagement and Mediterranean diet (MD) adherence are important for improving health. Children's lifestyles have been affected by lockdown due to the COVID-19 pandemic. It is also possible that the initial detrimental impact of the pandemic on children's health continues beyond the period in which confinement was imposed. Thus, the aim of the present study was to analyze PA engagement, MD adherence and screen time in children during confinement and compare findings with data gathered during pre-and post-confinement periods. The initial sample included 55 children aged 10-12 years. Of these, eighteen could not be followed up. The final sample was composed of 37 children aged 12-13 years. All were primary school students in the province of Granada, Spain. Validated questionnaires were administered to evaluate PA (PAQ-C) and Mediterranean diet adher-ence (KIDMED). The FAS III test was used to evaluate socioeconomic status and an ad-hoc questionnaire was developed to collect sociodemographic data and evaluate screen time. Children exhibited worse PA levels and screen time during confinement when com-pared with pre-confinement and post-confinement periods. Screen time habits acquired during confinement continued afterwards. In contrast, PA levels were higher following confinement than both during and afterwards.
