A Novel School-clinic-community Online Model of Child Obesity Treatment in Singapore During COVID-19

Background: The Coronavirus 2019 (COVID-19) is an infectious disease, which was first identified in December 2019 and has then spread rapidly around the world. COVID-19 spreads mainly through respiratory droplets and causes people to experience mild to moderate respiratory illness. On 11 March 2020, the World Health Organisation (WHO) declared COVID-19 a pandemic. With the surge in cases and to contain the spread of this disease, Singapore implemented a circuit breaker to reduce movements and interactions in public and private places. People are advised to stay at home and practise social distancing. With restrictions in movements, parents and children are likely to be more sedentary in this pandemic. There is an urgent need to move face-to-face interventions to online interventions as it is important to be active in this period. Childhood obesity threatens the health of US and Singapore populations. In the US, 30% of children are overweight, 17% have obesity, and 8% have severe obesity. In Singapore, 13% of children have obesity, and approximately half of all overweight children live in Asia. In both countries the prevalence is increasing, especially amongst the lower income populations, and is associated with future cardiovascular and metabolic disease. In US, obesity is most prevalent in Black and Hispanic populations and in Singapore, obesity affects Malays and Indians disproportionately. The underlying drivers and potential solutions thus share many common factors. The current evidence shows a clear dose-response effect with increasing number of hours of treatment, with a threshold for effectiveness at \> 25 hours over a 6-month period. A key gap in delivering this recommendation is meeting the intensity, and delivering comprehensive treatment that is culturally relevant, engaging to families, and integrated within the community context. The study is an online pilot randomised controlled trial among children aged 4-7 with obesity, in Singapore, to test a novel school-clinic-community online intervention, the KK Hospital (KKH) Sports Singapore program, for child obesity treatment with usual care. The primary outcome is intensity of treatment as measured by hours of exposure to intervention. The online KKH Sports Singapore program involves 4-6 weekly online sessions of physical activity and nutrition lessons for children and parents.
