High Blood Pressure in Young Adults Could Mean Heart Trouble in Middle Age

February 5, 2014

High_Blood_PressureFeb 5: Twenty-somethings with even mildly elevated blood pressure may face an increased risk of clogged heart arteries by middle age, a long-term U.S. study finds.

The study, which tracked nearly 4,700 people, found that even "pre-hypertension" in young adulthood was linked to a higher risk of calcium buildup in the heart arteries 25 years later.

Experts said the findings send a message to young adults: Know your blood pressure numbers and, if needed, change your lifestyle to get them in the normal range.

"What you do as a young adult matters," said lead researcher Norrina Allen, an assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine, in Chicago. "We shouldn't wait until middle-age to address blood pressure."

That same message goes for doctors, too, Allen added. "Many doctors might not think a small elevation in blood pressure (in a young adult) even warrants a discussion," she said.

The new study appears in the Feb. 5 issue of the Journal of the American Medical Association.

The good news, Allen noted, is that lifestyle changes can "absolutely" be enough for a healthy young person with moderately elevated blood pressure.

An expert not involved in the study agreed. "Lifestyle changes do work. Even within the span of a few months, blood pressure can dramatically improve," said Dr. George Bakris, a professor of medicine at University of Chicago Medicine who wrote an editorial published with the study.

Diet changes, such as cutting out salty processed foods and getting more fruits and vegetables, are key. So is moderate exercise, like walking, study author Allen said. And if you're overweight, even cutting a few pounds can help lower blood pressure.

Bakris pointed to some steps that are less well known: Watch your drinking, since alcohol can raise blood pressure; and get enough sleep.

"It's important to get at least six hours of uninterrupted sleep each night," Bakris said. "Ideally, you'd get six to eight hours."

In the United States, about one-third of adults have high blood pressure, which is defined as a systolic pressure (the top number) of 140 or higher, or a diastolic pressure (the bottom number) of 90 or higher, according to the U.S. Centers for Disease Control and Prevention. "Normal" blood pressure is anything below 120/80, while numbers that fall in between "normal" and "high" are considered "pre-hypertension."

The new findings are based on 4,681 people from four U.S. cities who were between the ages of 18 and 30 when they entered the study in the mid-1980s. Over the next couple of decades, they had their blood pressure taken periodically. At year 25, they underwent CT scans to look for calcium buildup in the arteries -- which is considered an early sign of heart disease.

Overall, Allen's team found that study participants had five general "trajectories" in blood pressure over time.

Five percent had slightly elevated blood pressure at their first measurement, which then kept increasing over the years. That group had the worst-looking arteries 25 years later: One-quarter had calcium "scores" above 100, which is linked to a higher-than-normal risk of suffering a heart attack in the next several years.

In contrast, among people who had normal blood pressure throughout the study, only 4 percent had calcium scores that high.

But it wasn't only the young people with ever-increasing blood pressure who showed artery trouble later on.

Another 19 percent had blood pressure that was slightly elevated in young adulthood, but stable thereafter -- hovering in the pre-hypertension range over the years. In that group, 17 percent ended up with a calcium score above 100.

Of course, young people with elevated blood pressure might have other health issues, too. But even when Allen's team took into account for other factors -- like smoking, weight and current blood pressure -- a person's lifetime blood-pressure pattern was still important.

According to Bakris, it all suggests that elevated blood pressure, left unchecked, can start taking a toll on the arteries early in life. "If you wait until your 40s or 50s to address it, the damage to the arteries may already be done," he said.

He suggested that most healthy young people have their blood pressure checked every couple of years. But if they have a strong family history of high blood pressure -- such as two parents who developed the condition at a fairly young age -- more-frequent blood pressure checks would be in order, Bakris said.

Washington D.C., Jan 3: A new study has found out that diet significantly affects the mental health and well being of an individual.

The study was published in the journal European Neuropsychopharmacology.

"We have found that there is increasing evidence of a link between a poor diet and the worsening of mood disorders, including anxiety and depression. However, many common beliefs about the health effects of certain foods are not supported by solid evidence," said the lead researcher, Professor Suzanne Dickson.

According to the researchers, the link between diet and mental health can be firmly established in certain cases like that of the ability of a ketogenic diet being helpful for children with epilepsy and the impact of vitamin B12 deficiency on poor memory, depression and fatigue.

"With individual conditions, we often found very mixed evidence. With ADHD for example, we can see an increase in the quantity of refined sugar in the diet seems to increase ADHD and hyperactivity, whereas eating more fresh fruit and vegetables seems to protect against these conditions," said Dickson

But there are comparatively few studies, and many of them don't last long enough to show long-term effects," added Dickson.

The study further concludes that some food items can be associated with treatment and the betterment of certain mental health conditions.

While coughing, fever and difficulty in breathing are common symptoms of COVID-19, a new case study has found that pink eye is also a reason to be tested for the disease.

The study, published in the Canadian Journal of Ophthalmology, determined that conjunctivitis and keratoconjunctivitis can also be primary symptoms of COVID-19.

The researchers noted that in March, a 29-year-old woman arrived at the Royal Alexandra Hospital's Eye Institute of Alberta with a severe case of conjunctivitis and minimal respiratory symptoms.

After the patient had undergone several days of treatment with little improvement -- and after it had been determined that the woman had recently returned home from Asia -- a resident ordered a COVID-19 test.

The test came back positive, according to the researchers.

"What is interesting in this case, and perhaps very different to how it had been recognised at that specific time, was that the main presentation of the illness was not a respiratory symptom. It was the eye," said Carlos Solarte, an assistant professor at the University of Alberta in Canada.

"There was no fever and no cough, so we weren't led to suspect COVID-19 at the beginning. We didn't know it could present primarily with the eye and not with the lungs," Solarte said.

Academic studies at the outset of the pandemic identified conjunctivitis as a secondary symptoms in about 10 to 15 per cent of COVID-19 cases, he said.

Since then, scientists have gained greater knowledge of how the virus can transmit through and affect the body's mucous membrane system, of which the conjunctiva -- the clear, thin membrane that covers the front surface of the eye -- is an extension.

While the finding provides important new health information for the public, it also makes eye exams more complicated for ophthalmologists and staff, the researchers noted.

"The patient in this case eventually recovered well without any issues. But several of the residents and staff who were in close contact with the patient had to be under quarantine," said Solarte.

"Fortunately, none who were involved in her care also tested positive," he said.

Patients coming into an eye clinic with conjunctivitis and keratoconjunctivitis are now treated as potential cases of COVID-19 and extra precautions are taken by staff, according to the researchers.

The health and future of every child and adolescent worldwide is under immediate threat from ecological degradation, climate change and exploitative marketing practices that push fast food, sugary drinks, alcohol and tobacco at children, said a new report on Wednesday.

No single country is adequately protecting children's health, their environment and their futures, according to the report by a commission of over 40 child and adolescent health experts from around the world.

The commission, convened by the World Health Organization (WHO), the United Nations children's agency, Unicef, and medical journal the Lancet, found that while the poorest countries need to do more to support their children's ability to live healthy lives, excessive carbon emissions --disproportionately from wealthier countries -- threaten the future of all children.

"Despite improvements in child and adolescent health over the past 20 years, progress has stalled, and is set to reverse," said former Prime Minister of New Zealand and Co-Chair of the Commission, Helen Clark.

"It has been estimated that around 250 million children under five years old in low- and middle-income countries are at risk of not reaching their developmental potential, based on proxy measures of stunting and poverty. But of even greater concern, every child worldwide now faces existential threats from climate change and commercial pressures," Clark said.

The report, titled "A Future for the World's Children?", includes a new global index of 180 countries, comparing performance on child flourishing and sustainability, with a proxy for greenhouse gas emissions, and equity, or income gaps.

India ranked 131 among the 180 countries in the index.

The index shows that children in Norway, the Republic of Korea, and the Netherlands have the best chance at survival and well-being, while children in the Central African Republic, Chad, Somalia, Niger and Mali face the worst odds.

However, when the authors took per capita CO2 emissions into account, the top countries trail behind: Norway ranked 156, the Republic of Korea 166, and the Netherlands 160.

Each of the three emits 210 per cent more CO2 per capita than their 2030 target.

The US, Australia, and Saudi Arabia are among the ten worst emitters.

If global warming exceeds 4 degree Celsius by the year 2100 in line with current projections, this would lead to devastating health consequences for children, due to rising ocean levels, heatwaves, proliferation of diseases like malaria and dengue, and malnutrition, said the report.

The only countries on track to beat CO2 emission per capita targets by 2030, while also performing fairly (within the top 70) on child flourishing measures are: Albania, Armenia, Grenada, Jordan, Moldova, Sri Lanka, Tunisia, Uruguay and Vietnam.

The report also revealed the distinct threat posed to children from harmful marketing. Evidence suggests that children in some countries see as many as 30,000 advertisements on television alone in a single year, while youth exposure to vaping (e-cigarettes) advertisements increased by more than 250 per cent in the US over two years, reaching more than 24 million young people.

Children's exposure to commercial marketing of junk food and sugary beverages is associated with purchase of unhealthy foods and overweight and obesity, linking predatory marketing to the alarming rise in childhood obesity, said the report.

The number of obese children and adolescents increased from 11 million in 1975 to 124 million in 2016 - an 11-fold increase, with dire individual and societal costs.
