Ottawa, October 23, 2016: Even if you are up to 20 per cent less fit than your population average, it is sufficient to prevent risk factors like diabetes, hypertension, obesity that affect people with heart disease, finds a study.

Physical inactivity along with risk factors like depression, diabetes, dyslipidemia, hypertension, obesity, excess weight, and smoking may lead to heart disease, which is one of the leading causes of death in the world, representing 31 per cent of global mortality, the study says.

To measure the impact of physical fitness on heart disease risk factors, the researchers selected 205 men and 44 women with heart disease, including coronary artery disease, stroke, congestive heart failure, and heart valve disease, and had them undergo a cycle ergometer (stationary bike) stress test to determine their fitness level.

The results showed that normal physical fitness, even up to 20 per cent below the population average, is sufficient to have a preventive effect on five of the eight risk factors affecting people with cardiovascular disease–abdominal circumference, diabetes, hypertension, obesity, and excess weight.

“It is common to meet people entering a cardiac rehab centre who are totally out of shape and whose exercise is irregular or non-existent, which has a harmful effect on general and cardiovascular health,” said Daniel Curnier, a professor at the University of Montreal, Canada, said in a statement.

The easiest way to achieve normal physical fitness is to follow the recommendations of the World Health Organization — 150 minutes per week of moderate exercise or 75 minutes of vigorous exercise, the study suggested.

The results have also demonstrated the importance of a good fitness level, before and after a heart attack, to produce the preventive effect on depression.

The study sheds new light on the overall role of physical fitness in the development of cardiovascular risk factors in patients with cardiovascular disease. (IANS)

WHO: Nearly 1 Billion People Risk Hearing Loss by 2050

Problems resulting from hearing loss are expected to rise because of a growing and aging population - a population that is expected to reach 9 billion by 2050

On the occasion of World Hearing Day, Saturday, the World Health Organization (WHO) is warning one in 10 people globally, or more than 900 million, are at risk of disabling hearing loss by 2050 unless preventive action is taken now.

The World Health Organization reports 466 million people around the world currently suffer from disabling hearing loss. The annual cost to countries in direct health services and lost productivity resulting from this disability is estimated at $750 billion.

Problems resulting from hearing loss are expected to rise because of a growing and aging population – a population that is expected to reach 9 billion by 2050.

Shelly Chadha, a technical officer in the WHO’s Department of Prevention of Deafness and Hearing Loss, says the rise in the aging population does not mean that an increase in hearing loss is inevitable. She says there are many factors besides aging that affect hearing.

“These may be factors such as infectious diseases, which we may encounter in childhood – rubella or mumps, meningitis or ear infections. There may be factors such as exposure to loud sounds, to loud music or noise at workplaces. Many of these causes are preventable, and by addressing them, we can reduce or minimize the risk of hearing loss,” Chadha said.

The WHO reports about 60 percent of hearing loss in children can be prevented. Measures include immunizing children against infectious diseases, screening and treating chronic ear infections, avoiding the use of drugs harmful to hearing, and controlling exposure to loud sounds and music.

It says these devices are of great benefit to the hard-of-hearing because they make it possible for them to better communicate and socialize with others. (VOA)
