Obesity Among Children Surpasses Underweight Globally
A recent study by Unicef reveals a concerning trend—there are now more obese children in the world than those who are underweight. About 10% of children aged 5 to 19, which amounts to roughly 188 million, are now classified as obese.
The researchers attribute this shift primarily to the transition from traditional diets to ones heavily centered on inexpensive, ultra-processed foods that are high in calories. Unicef is calling on governments to safeguard children’s diets from unhealthy ingredients and prevent the ultra-processed food industry from influencing policy decisions.
Changing Definitions of Malnutrition
Traditionally, malnutrition was often associated with underweight children, but that’s evolving. Now, obesity’s impact on children’s health is equally concerning, even in lower-income nations. A child is deemed overweight when their weight is significantly above what’s considered healthy for their age, sex, and height. Obesity—a more severe form of being overweight—correlates with increased risks of type-2 diabetes, heart disease, and certain cancers later in life.
Throughout childhood, proper nutrition, including sufficient fruits, vegetables, and protein, is crucial for growth and cognitive development. Unfortunately, many children are increasingly turning to ultra-processed foods, which often contain high levels of sugar, unhealthy fats, and various additives. Catherine Russell, Unicef’s executive director, warns that the obesity epidemic is a worrying issue that significantly affects children’s health and development.
Current Obesity Rates
While undernutrition remains a significant challenge for children under five in developing nations, Unicef’s latest data shows a decline in underweight cases among 5-19 year-olds—from nearly 13% in 2000 to 9.2% today. Conversely, the obesity rate has surged from 3% to 9.4%, which means that nearly one in ten children are now classified as obese. Overall, around 20% of school-aged children and adolescents are overweight or obese, totaling about 391 million globally.
Obesity now surpasses underweight figures in all regions except for sub-Saharan Africa and South Asia. Notably high obesity rates can be found in several Pacific Island states—Niue at 38%, Cook Islands at 37%, and Nauru at 33%. High-income countries are also grappling with severe obesity issues: Chile reports 27%, while both the United States and the United Arab Emirates stand at 21% among this age group.
According to Russell, many nations are experiencing the “double burden of malnutrition,” which includes both stunting and obesity, necessitating targeted interventions. She emphasizes the need for accessible, nutritious food to support every child’s growth and development, along with urgent policies that assist parents in obtaining healthy food options for their kids.
The Urgency for Action
Unicef warns that failing to address obesity may lead to significant health repercussions and economic burdens. The report predicts that by 2035, the financial impact of overweight and obesity could reach over $4 trillion annually. To combat this, it recommends government action related to food labeling and marketing.
Possible measures include banning ultra-processed foods from schools, implementing taxes on unhealthy food and drinks, and encouraging reformulations of products to limit unhealthy substances. Furthermore, it calls for ensuring that policy-making remains free from the influence of the ultra-processed food industry, advocating for transparency in political lobbying.
