Rising Childhood Obesity Outpaces Underweight Rates Globally
For the first time, a UN report reveals that more children worldwide are classified as obese than underweight, raising alarms about the growing prevalence of ultra-processed junk food in their diets.
According to UNICEF, around 188 million school-age children and teenagers, or about 10%, are affected by obesity. This condition poses significant health risks and developmental challenges, possibly leading to severe diseases later in life.
Catherine Russell, the executive director of UNICEF, emphasized that the term “malnutrition” now extends beyond just underweight issues. “Obesity is increasingly alarming,” she noted, pointing out that ultra-processed foods are displacing healthier options like fruits, vegetables, and protein—especially important for children’s growth and mental health.
The report indicates that while 9.2% of children aged five to 19 are underweight, a slightly higher 9.4% are categorized as obese. This marks a shift from the year 2000, when nearly 13% of children were underweight and only about 3% were obese.
Obesity has now eclipsed underweight statistics as a more common nutrition issue in nearly every part of the world, except for sub-Saharan Africa and South Asia. Oddly, the issue persists even in nations where many children still suffer from hunger or related health issues.
The report, titled Feeding Profit: How Food Environments are Failing Children, utilized data from over 190 countries, drawing information from UNICEF, the World Health Organization, and the World Bank. It found that one in five children aged five to 19 are considered overweight, with a growing portion—around 42% as of 2022—now classified as obese, compared to just 30% in 2000.
The highest obesity rates are noted in Pacific Island nations, where traditional diets are increasingly being replaced with cheap, energy-dense imported foods. For instance, 38% of children in Niue and 37% in the Cook Islands are deemed obese. Notably, wealthier countries like Chile (27%), the U.S. (21%), and the UAE (21%) also show high obesity rates.
In the UK, the proportion of overweight children rose from 29% in 2000 to 30% in 2022, while the obesity rate climbed from 9% to 11%. The sharpest increases in overweight rates were observed in low- and middle-income regions, where numbers have more than doubled since 2000. This correlates with the rise of modern grocery retail, online shopping, and food delivery services, where ultra-processed foods are often cheaper than fresh options.
Childhood obesity is linked to a greater likelihood of heart disease, type 2 diabetes, and certain cancers in adulthood. The potential health risks associated with ultra-processed foods—like sugary cereals, snacks, and ready-made meals—are gaining international scrutiny. These foods often contain high levels of added sugars, fats, and salts, as well as various additives due to industrial processing.
The report cautions that ultra-processed foods are prevalent in stores and schools and heavily marketed to both children and parents, making them hard to resist, almost as if it’s not merely about personal choice anymore.
Nomathemba Chandiwana from the Desmond Tutu Health Foundation in Cape Town highlighted the complexity of addressing malnutrition. “We often associate malnutrition strictly with underweight issues,” she remarked. “However, obesity carries equally significant long-term effects.” She pointed out that many children face both obesity and stunting due to poor nutrition, exacerbated by relentless advertising for fast food, even within schools.
She noted the ongoing challenge of tackling undernutrition alongside obesity in South Africa, which, despite being a middle-income country, battles significant inequality. Many children find themselves in an environment filled with unhealthy food choices, making the situation even more complicated.
The economic ramifications of rising childhood obesity are also concerning. Previous estimates by UNICEF suggest that the yearly global cost of obesity could exceed $4 trillion by 2035.
The report acknowledges a positive step by Mexico in banning the sale of ultra-processed foods in schools. However, it cautions that the questionable practices of this industry undermine efforts to legislate and protect children from harmful food environments.
UNICEF urges governments to take action by implementing labeling guidelines, marketing bans, taxes, and subsidies aimed at providing vulnerable families with access to nutritious foods. There should be robust measures to ensure the food industry doesn’t interfere in public policy development, the report concluded.
