(Press-News.org) A new study in the European Heart Journal shows that people who develop type 1 diabetes in adulthood have an increased risk of cardiovascular disease and death, and that those diagnosed later in life do not have a better prognosis than those diagnosed earlier. The study, conducted by researchers at Karolinska Institutet in Sweden, points to smoking, poor glucose control and obesity as the main risk factors.
Type 1 diabetes used to be called childhood diabetes but can start at any time during life. However, research on adult-onset type 1 diabetes is limited. The researchers behind the current study wanted to investigate the risk of cardiovascular disease and death in this group, particularly for those diagnosed after the age of 40.
The registry-based study identified 10 184 people diagnosed with type 1 diabetes in adulthood between 2001 and 2020 and compared them to 509 172 matched people in the control group.
The study shows that these people with adult-onset type 1 diabetes had a higher risk of cardiovascular disease and death from all causes, including cancer and infections, compared to the control group.
“The main reasons for the poor prognosis are smoking, overweight/obesity and poor glucose control. We found that they were less likely to use assistive devices, such as insulin pumps,” says first author Yuxia Wei, postdoctoral fellow at the Institute of Environmental Medicine, Karolinska Institutet.
The results emphasise the seriousness of type 1 diabetes, even when it starts later in life, the researchers say.
“But we show that the prognosis can be significantly improved by preventing smoking and obesity and improving glucose control, not least in people diagnosed at older ages,” explains senior author Sofia Carlsson, senior lecturer and associate professor at the same department.
The researchers plan to continue investigating adult-onset type 1 diabetes, including risk factors for developing the disease and the prognosis of other outcomes, such as microvascular complications. Optimal treatment in adult-onset type 1 diabetes, including the effect of pump use and other advanced technologies, also needs to be explored.
“We hope to shed light on these issues in the coming years,” concludes Sofia Carlsson.
The study was funded by the Swedish Research Council and the Swedish Diabetes Foundation, among others. The researchers report that there are no conflicts of interest.

Onion-like nanoparticles found in aircraft exhaust
2025-05-14
1. Background and purpose of the study
Aircraft emit nanoparticles (<50 nm Note 1 in diameter) into the atmosphere, from the ground to the upper troposphere. Studies in Europe, the U.S., and Japan have reported high concentrations of particles in and around airports Ref 1, and there is worldwide concern regarding the effects on human health. The atmospheric heating effects by contrails generated from aircraft exhaust particles are also known, and research is being conducted to assess their potential impacts on climate. Particle ...
Chimpanzees use medicinal leaves to perform first aid
2025-05-14
Scientists studying chimpanzees in Budongo Forest, Uganda, have observed that these primates don’t just treat their own injuries, but care for others, too — information which could shed light on how our ancestors first began treating wounds and using medicines. Although chimpanzees elsewhere have been observed helping other community members with medical problems, the persistent presence of this behavior in Budongo could suggest that medical care among chimpanzees is much more widespread than we realized, and not confined ...
New marine-biodegradable polymer decomposes by 92% in one year, rivals nylon in strength
2025-05-14
Nylon-based products such as clothing and fishing nets are notoriously slow to degrade, especially in marine environments, contributing significantly to global ocean pollution. A Korean research team has now developed an innovative material that can be produced using existing manufacturing infrastructure and effectively addresses this problem.
A joint research team led by Dr. Hyun-Yeol Jeon and Dr. Hyo-Jeong Kim at the Korea Research Institute of Chemical Technology (KRICT), Senior Researcher Sung-Bae Park, Professor Dong-Yeop Oh at Inha University, and Professor Je-Young ...
Manitoba Museum and ROM palaeontologists discover 506-million-year-old predator
2025-05-14
Palaeontologists at the Manitoba Museum and Royal Ontario Museum (ROM) have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. The results are announced in a paper in the journal Royal Society Open Science.
Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group known as the radiodonts, which also included the famous Anomalocaris canadensis, a meter-long predator that shared ...
Not all orangutan mothers raise their infants the same way
2025-05-14
A new study of wild Sumatran orangutans by researchers at the Max Planck Institute of Animal Behavior (MPI-AB) has found that mothers consistently differ in their maternal behaviors toward their infants, even after controlling for biological, social, and environmental factors. Mothers also consistently vary from one another in how flexibly they adjust their parenting as their infants grow. For this study, the researchers analysed data on six maternal behaviors collected over 15 years.
“Our study shows that Sumatran orangutan mothers are not all the same when it comes to parenting behaviors,” said Revathe Thillaikumar, a postdoctoral researcher at MPI-AB and ...
CT scanning helps reveal path from rotten fish to fossil
2025-05-14
Scientists have found that X-Ray scanning reveals secrets of fossil formation without disturbing the decay of buried carcasses
A new study published in Palaeontology has confirmed that X-ray computed tomography (XCT scanning) can be used to monitor decomposing organisms without altering the natural decay process – a vital step for understanding how fossils form.
A research team from the University of Birmingham entombed dead zebrafish within sediment to test whether repeatedly zapping decaying specimens with X-rays would change how they decompose. Their findings suggest this non-invasive imaging technique allows scientists to watch decay happen in real-time without disturbing ...
Physical activity + organized sports participation may ward off childhood mental ill health
2025-05-13
Physical activity in early childhood, especially taking part in organised sports,may ward off several mental health disorders in later childhood and adolescence, suggests research published online in the British Journal of Sports Medicine.
But there seem to be clear sex differences in the observed protective effects, depending on the condition, the findings indicate.
The prevalence of mental ill health among children and teens has risen sharply worldwide, with a heightened vulnerability to stress thought to partially explain the increase, note the researchers.
Physical activity ...
Long working hours may alter brain structure, preliminary findings suggest
2025-05-13
Long working hours may alter the structure of the brain, particularly the areas associated with emotional regulation and executive function, such as working memory and problem solving, suggest the findings of preliminary research, published online in Occupational & Environmental Medicine.
Ultimately, overwork may induce neuroadaptive changes that might affect cognitive and emotional health, say the researchers.
Long working hours have been linked to heightened risks of cardiovascular disease, ...

Lower taxes on Heated Tobacco Products are subsidising tobacco industry – new research
Governments missing out tax revenues, hampering health policy
Governments which impose lower taxes on heated tobacco products in the hope of encouraging smokers away from conventional cigarettes are effectively subsidising the tobacco industry, missing out on much-needed tax revenues and hampering their own public health initiatives, new research from the University of Bath shows.

Recognition from colleagues helps employees cope with bad work experiences
2025-05-13
Being appreciated by colleagues can help employees cope with negative experiences at work, according to a new study involving the University of East Anglia (UEA).
Researchers found that employees experience ‘embitterment’ - an emotional response to perceived workplace injustice - on days when they are assigned more unreasonable tasks than usual.
This negative emotion not only affects their work but also spills over into their personal lives, leading to an increase in rumination, the repetitive dwelling on negative feelings and their causes. ...
