Study finds some 40% of Chinese children face obesity by 2030
A comprehensive study recently unveiled alarming projections that nearly 40% of Chinese children and adolescents are on track to have overweight or obesity by the year 2030 if current upward trends persist. This pressing issue has prompted calls from experts for immediate action to mitigate the looming health crisis, with proposed strategies including the implementation of a 20% levy on sugar-laden beverages.
The research, which was published in The Lancet Regional Health last month and conducted by a collaborative team from the School of Public Health at Peking University and the United Nations Children’s Fund, highlights the swift rise in obesity rates among the youth in China, pinpointing significant consequent health and financial repercussions.
The study’s forecasts paint a grim picture, estimating a staggering lifetime economic toll of 218 trillion yuan (approximately $31.6 trillion) from 2025 to 2092, attributable to the prevailing rates of obesity among children and adolescents in the absence of intervention strategies.
Zhou Maigeng, Deputy Director of the National Center for Chronic and Noncommunicable Disease Control and Prevention at the Chinese Center for Disease Control and Prevention, stressed that the economic strain posed by the increasing prevalence of children with overweight and obesity is often overlooked, as many related health complications have yet to manifest.
Alarm bells have already been sounded by data concerning adult obesity, which forewarns of the annual costs of chronic diseases linked to excess weight reaching 49 billion yuan by 2030, according to Zhou.
The upward trajectory of childhood and adolescent obesity in China has been startling, with prevalence rates soaring from a relatively modest 8.8% in 2000 to an estimated 37.9% in 2020—an increase of 400% over two decades. This surge has not only eclipsed the global average but also surpassed rates observed in certain Western and upper-middle-income nations. Without decisive action, researchers warn that these figures could exceed 60% by 2030.
In response to this growing public health concern, China has initiated several national interventions aimed at curbing the trend, focusing primarily on enhancing nutrition and physical activity within schools. The proposed introduction of a 20% tax on sugar-sweetened beverages, coupled with tighter restrictions on marketing unhealthy food products to children, has been identified as the most effective course of action.
This recommendation aligns with the World Health Organization’s guidance issued in December, urging nations to adopt or amplify existing taxes on sugary drinks as a measure to safeguard public health. The call to action is supported by evidence from countries like Mexico, South Africa, and the United Kingdom, where such fiscal policies have yielded positive outcomes.
Zhang Man, a researcher at Peking University, emphasised the importance of grounding policy decisions in scientific evidence and underscored the need for ongoing monitoring and evaluation of intervention impacts, suggesting adjustments based on observed results to enhance efficacy.
