According to a new study, obesity and overweight rates are being spiral due to “monumental social failure” due to “monumental social failure”, with more than half of adults and about one -third of children and youths are ready to be affected by 2050.

It represents more than 3.8 billion adults and 746 million children and adolescents, published in Lancet.

Obesity is associated with increasing risk of serious health problems like diabetes, some cancer and heart disease.

“The unprecedented global epidemic of overweight and obesity is an intensive tragedy and a monumental social failure,” said Professor Immimanula Gakidau, the lead author of the Health Matrix and Evaluation Institute at Washington University in America.

The team used data from 204 countries and regions to come up with its estimates and projects, which could be without future action.

He said that over the last three decades, overweight and obesity rates have exceeded double, with more than 2.1 billion adults and 493 million youths have been affected as 2021 at the age of 5-24 years.

While obesity were complex due to obesity, governments should use projections to help the population at the most risk, the researchers said, especially around improved access to healthy diets.

The study funded by the Gates Foundation had limitations including data gaps and the use of body mass index as a marker. Researchers said that the potential effect of obesity drugs has also not been taken into consideration, with heavy demands in rich countries where they are available.

The picture varies globally, but researchers said that quick increase in obesity among young people and increase in low and medium -income countries where health systems could not deal with the burden of coming, were particularly worrisome.

This involves an estimated 250% increase in overweight and obesity rates in sub-city Africa. Increased, 522 million adults and 200 million children and young people are partially motivated by population growth.

A separate study published on Monday, Atlas of World Obesity Federation of World Obesity also raised the issue.

“The most affected areas are developing countries,” said Simon Barquera, president of the Federation.

Obesity Atlas suggested that 79% of adults and 88% of children obese and overweight children will live in low and moderate income countries, and only 7% of all countries have enough health system to deal with it.

“This is actually one of the main public health challenges worldwide,” said Barquera.
