Study Shows That A Quarter of People Worldwide Will be Obese by 2045

Owing to current lifestyle trends, almost a quarter (22 per cent) of the people in the world will be obese by 2045, up from 14 per cent in 2017, researchers say.

Owing to current lifestyle trends, almost a quarter (22 per cent) of the people in the world will be obese by 2045, up from 14 per cent in 2017, researchers say.

The startling projections, presented at 2018 European Congress on Obesity in Vienna, also demonstrated that the prevalence of diabetes will increase from 9.1 percent to 11.7 percent by 2045, which will result in one out of eight people around the world to suffer from Type-2 diabetes.

“These numbers underline the staggering challenge the world will face in the future in terms of numbers of people who are obese or have Type-2 diabetes or both. As well as the medical challenges these people will face, the costs to countries’ health systems will be enormous,” said Alan Moses, Chief Medical Officer at the Novo Nordisk — a Denmark-based healthcare company.

Overweight means having more body weight than is considered normal or healthy for one's age or build, while obesity is the condition of the excess amount of body fat with a body mass index (BMI) of over 30.

According to the researchers, in order to prevent the prevalence of Type-2 diabetes from going above 10 percent in 2045, global obesity levels must be reduced by 25 percent.

For the study, the population of all countries from 2000-2014 was divided into age groups which were further subdivided on the basis of body mass index (BMI). The diabetes risk for each age and BMI group was then applied, allowing estimations of diabetes prevalence for each country each year.

The researchers said that immediate action will not result in reversing the epidemic of diabetes and obesity quickly, however, it is essential to prevent new cases of obesity and diabetes.

“Despite the challenge all countries are facing with obesity and diabetes, the tide can be turned – but it will take aggressive and coordinated action to reduce obesity and individual cities should play a key role in confronting the issues around obesity, some of which are common to them all and others that are unique to each of them,” Moses said.

Researchers Identify Genes Causing Obesity

Performing functional studies across other organisms, the team also identified two genes that were associated with significant increase in triglyceride and body fat across species

Researchers have identified genetic variants associated with obesity that is central to developing targeted interventions to reduce the risk of chronic illnesses like hypertension, Type-2 diabetes and heart disease.

The team from the University of North Carolina at Chapel Hill found genetic sites that affect human body’s size and shape, including height and obesity. The findings will help understand how genes can predispose certain individuals to obesity.

In the study, published in the journal Nature Genetics, researchers found 24 coding loci (or positions) — 15 common and nine rare — along chromosomes of individuals that predispose to higher waist-to-hip ratio.

Higher values of waist-to-hip ratio are associated with more incidence of diseases associated with obesity.

“For the first time, we were able to examine, on a large scale, how low-frequency and rare variants influence body fat distribution,” said North.

“A better understanding of the genetic underpinnings of body fat distribution may lead to better treatments for obesity and other downstream diseases obesity also impacts, for example Type-2 diabetes and heart disease,” suggested North.

Further analysis revealed pathways and gene sets that influenced not only metabolism but also regulation of body fat tissue, bone growth and adiponectin, a hormone that controls glucose levels and breaks down fat.
