Health effects of overweight and obesity over 25 years

A study published in the New England Journal of Medicine reports an increase in the prevalence and burden of disease related to high body mass index (BMI).

Researchers analysed data from the Global Burden of Disease (GBD) study including 68.5 million people. This data spans over 25 years, from 1990 to 2015. The GBD study collects obesity data in 195 countries worldwide including the Republic of Ireland and Northern Ireland. The main findings from the study include:

  • In 2015, 107 million children and 603 million adults were obese worldwide
  • The prevalence of obesity in children and adults has doubled in 73 countries since 1990
  • In 2015, excess weight was associated with 4 million deaths
  • In 2015, high BMI contributed to 120 million disability-adjusted life-years (DALY)*.
  • Cardiovascular disease was the leading cause of death and DALY related to high BMI. This was followed by diabetes.
  • High BMI resulted in 28.6 million years lived with disability
  • The global rate of death due to high BMI increased by 28.3% from 1990 to 2015

*Disability adjusted life years is a measure of the burden of disease, expressed as the years lost to ill-health, disability or premature death.
