Exercising Too Little Puts Your Health At Risk: WHO

In wealthier countries, the researchers said, a transition toward more sedentary jobs as well as sedentary forms of recreation and transport could explain higher levels of inactivity.

More than a quarter of the world’s adults — 1.4 billion people — exercise too little, putting them at higher risk of cardiovascular disease, type 2 diabetes, dementia and cancers, according to a World Health Organization-led study.

In 2016, around one in three women and one in four men worldwide were not reaching the recommended levels of physical activity to stay healthy — at least 150 minutes of moderate exercise or 75 minutes of vigorous exercise a week.

There has been no improvement in global levels of physical activity since 2001, according to the study, which was conducted by WHO researchers and published Tuesday in The Lancet Global Health.

The highest rates of lack of exercise in 2016 were in adults in Kuwait, American Samoa, Saudi Arabia and Iraq, where more than half of all adults were not active enough to protect their health.

By comparison, around 40 percent of adults in the United States, 36 percent in Britain and 14 percent in China did too little exercise to stay healthy.

“Unlike other major global health risks, levels of insufficient physical activity are not falling worldwide, on average, and over a quarter of all adults are not reaching the recommended levels of physical activity for good health,” said Regina Guthold of the WHO, who co-led the research.

Noncommunicable diseases

The WHO says insufficient physical activity is one of the leading risk factors for premature death worldwide. It raises the risk of noncommunicable diseases such as cardiovascular disease, cancer and diabetes.

By becoming more active, it says, people can easily achieve benefits such as improve muscular and cardiorespiratory fitness, better bone health, weight control and reduced risk of hypertension, heart disease, stroke, diabetes, depression and various types of cancer.

The study found that levels of low physical activity were more than twice as great in high-income countries compared with poorer nations, and had increased by 5.0 percent in richer countries from 2001 to 2016.

In wealthier countries, the researchers said, a transition toward more sedentary jobs as well as sedentary forms of recreation and transport could explain higher levels of inactivity. In less well-off countries, people tend to be more active at work and for transport, they said.

They urged governments to take note of these changes and put in place infrastructures that promote walking and cycling for transport and active sports and recreation. (VOA)

Here’s How Exercise Can Help Breast Cancer Survivors

Among those who completed the program, those who received the lifestyle intervention were about 50 per cent more likely to have disease-free survival than those who received the general recommendations

Survivors of early-stage breast cancer who exercise and eat a healthy diet are more likely to lose weight and experience higher rates of disease-free survival, a new study suggests.

The research is based on an examination of a lifestyle intervention that included exercise, diet, and at least one other component such as counselling, stress management, and discontinuing tobacco smoking.

The study showed that obesity and low physical activity are associated with higher risks of developing breast cancer, as well as an increased risk of recurrence and reduced survival.

“Lifestyle intervention might improve the prognosis of breast cancer patients if adherence is high,” said Wolfgang Janni from the University of Ulm in Germany.

“Many breast cancer survivors would like to contribute actively to improving their prognosis, and guiding them on lifestyle factors that can help them control weight is one possible way to positively impact patient outcomes,” said Janni.

For the study, the researchers enrolled 2,292 women among which all had a body mass index of 24 or higher.

Some women were randomly assigned to receive either telephone-based lifestyle intervention for two years while others received general recommendations for a healthy lifestyle alone.

Those who received the telephone calls were given advice on how to improve their diets, lower fat intake, increase physical activity, achieve moderate weight loss and other tips that were geared to their specific needs.

Findings, presented at the 2018 San Antonio Breast Cancer Symposium in the US, demonstrated that patients in the lifestyle intervention arm had lost an average of one kg, while the patients in the control group had gained an average of 0.95 kg.

Overall, 1,477 patients completed the lifestyle intervention. Those who completed the program had a 35 per cent higher rate of disease-free survival than those who began the program but did not complete it.
