Diabetes among young people has soared over last 30 years

The number of young people developing Type 2 diabetes has soared over the past 30 years, driven by obesity, a new study shows.

Data from over 200 countries and regions showed the rise particularly affected women under 30.

Generally Type 2 diabetes develops in middle-aged and older people and it carries an increased risk of serious health complications, such as heart disease, vision loss and death.

However, scientists discovered the incidence rate for type 2 diabetes in adolescents and young adults is increasing across the globe - from 117 per 100,000 people in 1990, to 183 in 2019.

One of the measurements in the study was disability adjusted life years (DALYs), and these increased globally from 106 per 100,000 in 1990 to 150 per 100,000 in 2019.

Mortality rate due to the disease across the globe increased from 0.74 percent per 100,000 to 0.77 per 100,000 in 2019.

The team at Harbin Medical University, China, found women under 30 generally had high mortality and DALY rates than men.

However, the sex split in mortality rate reversed once people passed 30 years old, except for undeveloped countries.

Regardless of the region, DALYs increased primarily because of high body mass index and in all countries, high body mass index was the main risk factor.

Writing in the BMJ, researchers argued weight control is essential to reduce the burden of early onset Type 2 diabetes, and countries should establish specific policies to deal with the disease effectively.

In 2019 the highest rates of type 2 diabetes came from those living in low-middle and middle sociodemographic index countries, as did the highest DALY rate.

Meanwhile, countries with a low sociodemographic index had fewest people diagnosed with the disease, but the highest mortality rate for the disease at the same time.

The study was the first to describe the global burden of the disease, and is the first to look at variations between the sexes in countries with different levels of socioeconomic development.

Risk factors of the disease also remained unclear until this research.

The team studied data from 204 countries and territories between 1990 and 2019, focussing on new cases, deaths, and DALYs.

The three focal points provide a measure of quality and quantity of life.

They also examined the proportional DALY attributable to different risk factors and revealed air pollution, smoking, low-fruit diets all contributed to the disease.

The team said: “Our study showed a clear upward trend of the burden of early onset Type 2 diabetes from 1990 to 2019.

“These findings provide a basis for understanding the epidemic nature of early onset Type 2 diabetes and call for urgent actions to deal with the issue from a global perspective.”
