A new study published in The Lancet Digital Health suggests that biological age of different organs could predict a person's risk of diseases such as cancer, dementia, and heart disease than their actual chronological age. The research analyzed long-term data from Whitehall II study, which had been followed by over 10,000 British adults for more than 35 years.

The blood plasma samples were collected between 1997 and 1999 from participants between ages 45 to 69. Researchers have now examined a follow up data from 6,235 participants, who were by then aged 65 to 89. This was done to see how aging of specific organ may correlate with the development of diseases over two decades.

What Organs Were Studied?

The study measured the biological age of nine key organs, including:

• Heart
• Blood vessels
• Liver
• Immune system
• Pancreas
• Kidneys
• Lungs
• Intestines
• Brain

The researchers were able to find that different organs aged at different rates in different people. In many of the cases multiple organs showed signs of faster aging within the same individual. What is important to note is that those with accelerated aging in certain organs had a higher risk of developing 30 out of the 40 age-related diseases the study had tracked.

Organ Aging And Disease Risk

Some organ-disease connections were expected—people with rapidly aging lungs were more likely to develop respiratory diseases, and those with aging kidneys had an increased risk of kidney-related conditions. However, the study also found less obvious associations.

For example, individuals with fast-aging kidneys were more prone to diseases in other organs, such as the liver and pancreas. Additionally, multiple fast-aging organs were linked to an increased risk of kidney disease.

One of the most surprising findings was that dementia risk was not best predicted by an aging brain but rather by the immune system’s biological age. This suggests that factors such as chronic inflammation and immune health may play a critical role in neurodegenerative diseases.

What Is Organ Specific Blood Tests?

The study also highlights the important of the potential of developing blood tests that could assess the biological age of specific organs. Unlike previous complex methods that measured the organ health, this new approach could make things simple to detect early signs of disease.

The leader author of the study Mika Kivimaki, who is also a professor at the University College London's Faculty of Brain sciences pointed out that such tests could be helpful when it comes to guiding personalized healthcare. In a news release, Kivimaki said, "They could advise whether a person needs to take better care of a particular organ and potentially provide an early warning signal that they may be at risk of a particular disease."

The study reinforces the idea that aging does not affect all organs equally and that looking beyond chronological age could offer better insights into disease prevention. By understanding which organs are aging more rapidly, medical professionals may be able to recommend targeted interventions for individuals at higher risk of specific conditions. Future advancements in organ-specific blood testing could revolutionize how we detect and manage age-related diseases, potentially leading to more personalized healthcare strategies.

A fall at home might look small, but for women older than 65, a broken hip can be a big and serious health problem. In real medical terms, this condition has a 20 to 30 percent chance of being deadly within the first year.

As people get older, their bones get weaker because of osteoporosis, which makes them more likely to break even from small falls. However, the bigger problem starts once the injury happens.

According to World Health organization (WHO), around 60 per cent of people living with osteoarthritis are women, yet awareness remains limited until symptoms begin to interfere with mobility and daily function.

Loss Of Muscles

Reports show that 70 per cent of women will get arthritis and osteoporosis. Most of them had no idea it was coming. HealthandMe spoke to experts to understand the reasons behind the trend.

Dr Gurdeep Avinash Ratra, Consultant - Orthopedics and Joint Replacement, Manipal Hospitals, Gurugram said that the development of these disorders is gradual and closely tied to physiological changes.

“After the age of 30, there is a steady decline in muscle mass, accompanied by a more rapid reduction in strength and power. With menopause, the significant fall in estrogen levels removes natural protection for bone density and joint health. Over time, this leads to increased bone fragility, reduced muscular support, and stress on joints, thereby elevating the risk of fractures and chronic joint conditions,” Ratra told HealthandMe.

Health Coach Prashant Desai in a post on social media platform X, noted that after the age of 30:

• muscle mass starts declining by 1 per cent every year.
• muscle strength declines three times faster.
• muscle power declines eight times faster.

Treatment

Experts said a hip fracture needs to be treated right away as a serious medical problem that requires care from many different medical specialists, not just a doctor who focuses on bones.

Dr Rajesh Kumar Verma, Director – Orthopedics & Joint Replacement, Max Super Speciality Hospital, Vaishali explained that limited movement can cause blood clots, chest infections, pressure sores, and loss of muscle quickly. Many patients also face a quick drop in their ability to take care of themselves, which can impact both their body and mind.

“Delayed treatment further increases risk. Early surgery and prompt recovery treatment help increase the chances of surviving and recovering better,” Verma told HealthandMe.

How to Prevent

• Maintaining a healthy waist circumference as an early indicator of metabolic health.
• Engaging in regular strength training to preserve bone density and muscle mass.
• Ensuring adequate protein intake to support muscle maintenance.
• Incorporating sufficient calcium and Vitamin D into the diet.
• Remaining physically active, with exercise beyond low impact activities alone.
• Get medical help right away if you fall or think you might have a broken bone.
• Have surgery as soon as your doctor suggests it, because it can help you recover better.
• Begin physiotherapy as soon as possible after the surgery to help restore movement and avoid any serious issues.
• Make sure to eat well, paying special attention to getting enough protein, calcium, and vitamin D.
• Check for fall risks at home by looking at things like lighting, floor surfaces, and handrails.

What to avoid

• Do not wait to go to the hospital, even if the hip fracture pain feels okay.
• Avoid staying in bed for long because a hip fracture can lead to infections, pressure sores, and blood clots.
• Do not skip osteoporosis treatment for hip fractures because it is very important to stop broken bones from happening again.
• Avoid skipping follow-ups or rehabilitation sessions for hip fractures after the surgery.

World Health Day serves as a reminder that regular preventive health check-ups stand as mandatory health assessments that all women need to undergo for their long-term health.

Many serious conditions, such as breast cancer, cervical cancer, thyroid disorders, diabetes, and cardiovascular diseases, often remain silent in their early stages, making regular screening the most effective way to detect them early, when treatment is simpler, less invasive, and more successful.

How Preventive Healthcare Can Help Women

Preventive healthcare enables women to take a proactive role in managing their health rather than responding to illness at an advanced stage. Early detection not only improves clinical outcomes but also effectively decreases treatment difficulties, emotional distress and financial costs while providing superior long-term life quality.

This also helps in identifying risk factors early, allowing timely lifestyle modifications that can prevent disease onset altogether.

Despite this, women often deprioritize their own health due to the multiple roles they juggle, balancing careers, caregiving responsibilities, and family needs. There is also a continued hesitation around discussing reproductive and intimate health concerns, along with a lack of awareness, fear of diagnosis, and social stigma, all of which contribute to delays in seeking timely care.

In many cases, women assume that the absence of symptoms indicates good health, which is a common but risky misconception.

Importance Of Routine Screening

Routine screenings such as Pap smears for cervical health, regular breast examinations, mammography where indicated, thyroid function tests, and basic metabolic screenings like blood sugar and cholesterol levels are critical tools in preventive care.

Periodic health check-ups also provide an opportunity for counselling on nutrition, mental well-being, hormonal health, and lifestyle management, areas that are often overlooked but equally important.

World Health Day serves as a reminder to shift from a reactive to a preventive approach. Prioritizing regular health check-ups, normalizing conversations around women’s health, and encouraging a culture of self-care can significantly improve outcomes. Investing in preventive healthcare is one of the most powerful steps women can take towards leading healthier, longer, and more empowered lives.

Aging is a significant factor in memory loss and cognitive decline. Now, a team of US researchers has pinpointed a single protein that drives these changes in the brains of the elderly.

In aging mice, higher levels of protein FTL1 weakened connections between brain cells, leading to memory decline.

But when FTL1 was reduced, the brain began to recover. It also rebuilt lost connections and restored memory performance, according to the study, published in Nature Aging.

"It is truly a reversal of impairments," said Saul Villeda, Associate Director at the University of California - San Francisco's Bakar Aging Research Institute and senior author of the paper. "It's much more than merely delaying or preventing symptoms."

While the research was carried out in aging mice, it holds immense potential for human brain function.

FTL1: A Key Driver Of Brain Aging

In the study, the researchers tracked shifts in genes and proteins in the hippocampus of mice. The FTL1 protein appeared consistently different between young and old animals.

Compared to young mice, the older mice showed higher levels of FTL1. They also had fewer connections between neurons in the hippocampus and performed worse on cognitive tests.

Increasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.

In older mice, the nerve cells that produced high amounts of FTL1 developed simplified structures, forming short, single extensions instead of the complex, branching networks seen in healthy cells.

Further experiments showed that in older mice, higher levels of the protein slowed cellular metabolism in the hippocampus -- the part of the brain responsible for learning and memory.

However, when researchers treated these cells with a compound that boosts metabolism, the negative effects were prevented.

A Promise For Future Brain Aging Therapies

Villeda believes these findings could pave the way for treatments that target FTL1 and counter its effects in the brain.

"We're seeing more opportunities to alleviate the worst consequences of old age," he said. "It's a hopeful time to be working on the biology of aging."
