Childhood Overweight and Obesity in Vietnam: A Landscape Analysis of the Extent and Risk Factors

Abstract

Tackling childhood overweight and obesity is critical not only to improve the health and well-being of children and adolescents, but also for entire populations and future generations. This paper provides the latest evidence on the extent of, and risk factors for, childhood overweight and obesity in Vietnam. The landscape analysis tool developed by the United Nations Children’s Fund (UNICEF) and World Health Organization (WHO) was used. A search for peer-reviewed articles in English on online databases was undertaken. Peer-reviewed Vietnamese articles were also retrieved from a range of sources. The prevalence of overweight among children aged under 5 years increased from 5.6% in 2010 to 7.4% in 2019. For overweight and obesity among children aged 5 to 19 years, prevalence rose from 8.5% and 2.5% in 2010 to 19% and 8.1% in 2020, respectively. Maternal malnutrition, gestational diabetes during pregnancy, and inadequate infant and young child feeding practices are all risk factors for early childhood overweight. Unhealthy diets, insufficient physical activity, and lack of sleep are among the risk factors for overweight and obesity among school aged children and adolescents. The prevention of overweight and obesity among Vietnamese children requires a whole-of-government, cross-sectoral approach to addresses the obesogenic environment that is negatively influencing the nutrition of children.
