Impact of the COVID-19 pandemic and related lockdown measures on lifestyle behaviors and wellbeing in children and adolescents with severe obesity

Introduction: COVID-19 lockdown measures have large impact on lifestyle behaviors and wellbeing of children. The aim of this mixed-methods study was to investigate the impact of COVID-19 lockdown measures on eating styles and behaviors, physical activity (PA), screen time, and health-related quality of life (HRQoL) in children (0-18 years) with severe obesity. Methods: During the first COVID-19 wave (April 2020), validated questionnaires were completed and semi-structured telephone interviews were conducted with parents of children with severe obesity (adult BMI-equivalent ≥35kg/m2) and/or with the children themselves. Changes in pre-pandemic versus lockdown scores of the Dutch Eating Behavior Questionnaire Children (DEBQ-C), Pediatric Quality of Life Inventory (PedsQLTM), and Dutch PA Questionnaire were assessed. Qualitative analyses were performed according to the Grounded Theory. Results: Ninety families were approached of which 83 families were included. Characteristics of the included children were: mean age 11.2 ± 4.6 years, 52% female, mean BMI SD-score +3.8 ± 1.0. Emotional, restrained, and external eating styles, HRQoL, and (non-educational) screen time did not change on group level (all p>0.05). However, weekly PA decreased (mean difference -1.9 hours/week, p=0.02), mostly in adolescents. In the majority of children, mean weekly PA decreased to ≤2 hours/week. Children with high emotional and external eating scores during lockdown or pre-existent psychosocial problems had the lowest HRQoL (p<0.01). Qualitative analyses revealed an increased demand for food in a significant proportion of children (n=21), mostly in children
