Obesity is now more prevalent among school-aged children and adolescents than being underweight, according to a recent report from UNICEF. This concerning shift has been attributed to increasingly unhealthy food environments around the world.
Utilising data from 2000 to 2022, UNICEF’s findings are based on research conducted by academics across various countries. The agency first anticipated this ‘tipping point’ in 2017, predicting that obesity rates would surpass those of underweight youth in the coming years.
Staggering Statistics on Youth Obesity
UNICEF’s analysis reveals that approximately 188 million, or 1 in 10, school-aged children and adolescents are classified as obese under World Health Organisation (WHO) criteria. This alarming statistic indicates a significant risk of lifelong health complications, including diabetes and cardiovascular diseases.
Since 2000, obesity rates in this age group have surged from 3% to 9.4%. In contrast, the prevalence of underweight children aged 5-19 has decreased slightly, from nearly 13% in 2000 to 9.2%. While this decline is notable, UNICEF underscores that underweight remains a significant issue alongside the growing rates of obesity.
Global Patterns in Obesity Rates
The report highlights that obesity now exceeds underweight rates in every region of the world except sub-Saharan Africa and South Asia. In certain Pacific Island nations, such as Niue and the Cook Islands, the situation is particularly dire, with nearly 40% of 5-19-year-olds affected by obesity. The United Arab Emirates and the United States follow closely, with obesity rates at 21%.
Contributing Factors to the Obesity Crisis
UNICEF attributes the rise in obesity to the prevalence of ultra-processed foods that are high in sugar, salt, and fat. The pervasive marketing of these unhealthy products has created a toxic food environment, which disproportionately impacts young people. Chris Van Tulleken, a professor of global health at University College London and a UNICEF supporter, stated, “Obesity is not a failure of parents or children. It’s the result of toxic food environments.”
A UNICEF poll of 64,000 young people aged 13-24 from 170 countries reveals that 75% of respondents have encountered advertisements for sugary drinks, snacks, or fast food within the past week. Alarmingly, even in conflict-affected regions, 68% of young people reported similar exposure to such marketing.
Urgent Calls for Action
In light of these findings, UNICEF is urging governments around the globe to take immediate action. Recommendations include implementing marketing restrictions and banning junk food in schools to protect children from unhealthy food environments. The agency emphasises that addressing the obesity crisis is critical for the health and well-being of future generations.
