More than a billion people obese

MORE than a billion people are living with obesity around the world, global estimates published in The Lancet show.

This includes about 880 million adults and 159 million children, according to 2022 data.

The highest rates are in Tonga and American Samoa for women and American Samoa and Nauru for men, with some 70-80 per cent of adults living with obesity.

Out of some 190 countries, the UK ranks 55th highest for men and 87th for women.

The international team of scientists say there is an urgent need for major changes in how obesity is tackled.

Obesity can increase the risk of developing many serious health conditions, including heart disease, type 2 diabetes and some cancers.

Ranking global obesity rates (the percentage of population classed as obese, after age differences are accounted for), researchers found:

The US comes 10th highest for men and 36th highest for women

India ranks 19th lowest for women and 21st lowest for men

China is 11th lowest for women and 52nd lowest for men

Senior researcher Prof Majid Ezzati, of Imperial College London, told the BBC: “In many of these island nations it comes down to the availability of healthy food versus unhealthy food.

“In some cases there have been aggressive marketing campaigns promoting unhealthy foods, while the cost and availability of healthier food can be more problematic.”

Prof Ezzati, who has been looking at global data for years, says he is surprised at the speed the picture has changed, with many more countries now facing an obesity crisis, while the number of places where people being underweight is regarded as the biggest concern, has decreased.

The report, spanning 1990 and 2022, found the rate of obesity quadrupled among children and adolescents. Meanwhile for adults, the rate more than doubled in women and nearly tripled in men.

At the same time, the proportion of adults classed as underweight has fallen by 50 per cent, but researchers emphasise it still remains a pressing problem, particularly among the poorest communities.

World Health Organization (WHO) director general Dr Tedros Adhanom Ghebreyesus said: “This new study highlights the importance of preventing and managing obesity from early life to adulthood, through diet, physical activity, and adequate care.”

He added that it would take the work of governments and communities and “importantly requires the co-operation of the private sector, which must be accountable for the health impacts of their products”.
