Increasing exercise levels at older age reduces risk of heart disease and stroke
BY Tom Walker
People over the age of 60 should increase their exercise levels in order to prevent heart disease and stroke.
Findings from a study of more than 1.1 million people aged 60+ found that those who did less moderate or vigorous physical activity as they got older had as much as a 27 per cent increased risk of heart and blood vessel problems.
In contrast, those who increased their levels of activity had a reduced risk of cardiovascular disease of up to 11 per cent.
The study, published in the European Heart Journal, shows that he link between levels of physical activity and risk of cardiovascular disease in older people held true even for those with disabilities and chronic conditions such as high blood pressure, high cholesterol levels and type 2 diabetes.
The research was carried out by the Seoul National University Graduate School Department of Biomedical Sciences in South Korea.
“The most important message from this research is that older adults should increase or maintain their exercise frequency to prevent cardiovascular disease," said Kyuwoong Kim, lead author of the study.
"Globally, this finding is of public health importance because the world’s population aged 60 years and older is expected to total two billion by 2050, which is an increase from 900 million in 2015 according to the World Health Organization.
"While older adults find it difficult to engage in regular physical activity as they age, our research suggests that it is necessary to be more physically active for cardiovascular health, and this is also true for people with disabilities and chronic health conditions.
“We believe that community-based programmes to encourage physical activity among older adults should be promoted by governments. Also, from a clinical perspective, physicians should ‘prescribe’ physical activity along with other recommended medical treatments for people with a high risk of cardiovascular disease.”
The research studied 1,119,925 men and women aged 60 years or older and who underwent two consecutive health checks provided by the Korean National Health Insurance Service (NIHS) from 2009 to 2010 and 2011 to 2012.
The participants were followed up until December 2016.
At each health check the participants answered questions about their physical activity and lifestyle. The researchers calculated the amount of moderate exercise (30 minutes or more a day of brisk walking, dancing, gardening) and vigorous exercise (20 minutes or more a day of running, fast cycling, aerobic exercise) per week at each screening, and how it had changed during the two years between the screenings.
The researchers found that people who moved from being continuously inactive at the 2009-2010 health check to being moderately or vigorously active three to four times a week at the 2011-2012 health check had an 11 per cent reduced risk of cardiovascular problems.
Those who were moderately or vigorously active one or two times a week at the first check had a 10 per cent reduced risk if they increased their activity to five or more times a week.
In contrast, those who were moderately or vigorously active more than five times a week at the first check and then became continuously inactive at the second check had a 27 per cent increased risk of cardiovascular problems.
When the researchers looked specifically at people with disabilities and chronic conditions, they found that those who changed from being inactive to being moderately or vigorously active three to four times a week also reduced their risk of cardiovascular problems. People with a disability had a reduced risk of 16 per cent, and those with diabetes, raised blood pressure or cholesterol levels had a reduced risk of between 4-7 per cent.
