More than one billion people living with obesity

The total number of children, adolescents and adults worldwide living with obesity has surpassed one billion, according to a global analysis published in The Lancet. These trends, together with the declining prevalence of people who are underweight since 1990, make obesity the most common form of malnutrition in most countries.

More than one billion people in the world are now living with obesity, according to global analysis published in The Lancet. The new analysis of global data estimates that among the world's children and adolescents, the rate of obesity in 2022 was four times the rate in 1990. Among adults, the obesity rate more than doubled in women and nearly tripled in men. In total, 159 million children and adolescents and 879 million adults were living with obesity in 2022.  

Between 1990 and 2022, the proportion of the world's children and adolescents who were affected by underweight fell by around one fifth in girls and more than one third in boys. The proportion of the world's adults who were affected by underweight more than halved over the same period.  

Obesity and underweight are both forms of malnutrition and are detrimental to people's health in many ways. This latest study provides a highly detailed picture of global trends in both forms of malnutrition over the last 33 years.
