Impact of the first COVID–19 lockdown on the lifestyle of elementary school children

Abstract COVID-19 lockdown affects people's daily routine and has an impact on their lifestyle. Recent studies documented associations between body weight changes and children's lifestyle during social isolation. Childhood obesity is associated with a higher risk of COVID-19 severity and mortality. Our aim was to assess the effects of lockdown due to the COVID-19 pandemic on children's sleep, screen time, physical activity, and eating habits. 387 parents of five elementary school students between 16 and 26 June 2020 were interviewed through an online questionnaire. Physical activity level decreased (63.8), sleep (60.9) and screen (5.64 ± 3.05 h/day) times and food intake (39.8) increased. 80.6 of parents reported changes in children's diet: increased consumption of fruits and vegetables (32.4), breakfast (15.5), water and sugar-free beverages (17.6), snacks (40.4), sugary drinks (9.9) was observed. Body weight increased in 44.4 of children. The results of the survey conducted under GYERE®-Children's Health Program are in line with the international literature findings: body weight change during the quarantine is significantly associated with food intake, snacking, sugary drinks, and we also found association with fruit and vegetable consumption and lack of breakfast. Effective strategies and electronic health interventions are needed to prevent sedentary lifestyle and obesity during lockdown
