New research presented at this year’s European Congress on Obesity (held online, 10-13 May) shows that for some children with severe obesity, the COVID-19 lockdown had a negative impact on physical activity and eating habits, and some (mostly aged under 10 years) exhibited increased demand for food. The study is by Dr. Ozair Abawi, Dr. Milla Welling and Dr. Bibian van der Voorn, Obesity Center CGG (Healthy Weight Centre), Erasmus MC-Sophia Children’s Hospital, University Medical Center Rotterdam, Rotterdam, The Netherlands, and colleagues.
