How obesity rate increased from 1990

The analysis of global data by the NCD Risk Factor Collaboration (NCD-RisC) and the World Health Organization (WHO) 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, according to the study.

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 being underweight more than halved over the same period..

Obesity rate in India

The study said that in India, the obesity rate increased from 1.2% in 1990 to 9.8% in 2022 for women and 0.5% to 5.4% in 2022 for men.

The obesity rate increased from 0.1% in 1990 to 3.1% in 2022 for girls and 0.1% to 3.9% in 2022 for boys. The prevalence of obesity in India ranked 27th lowest (174th highest) in the world for both girls and boys in 2022.

Causes of obesity

Overweight and obesity result from an imbalance of energy intake (diet) and energy expenditure (physical activity).

In most cases, obesity is a multifactorial disease due to obesogenic environments, psycho-social factors and genetic variants. In a subgroup of patients, single major etiological factors can be identified (medications, diseases, immobilization, iatrogenic procedures, monogenic disease/genetic syndrome).
