Every 10 minutes of a sedentary lifestyle “significantly” increases the risk of heart disease

It is estimated that five million deaths worldwide could be prevented each year if all inactive people started exercising.

Coronary heart disease is the most common type. It occurs when arteries become narrowed by a build-up of fatty substances along their walls, and can lead to death if left untreated.

The generally accepted causes of cardiovascular disease are being overweight, smoking, high cholesterol and diabetes. Lack of exercise is also often cited by health authorities as a cause. Inactivity can lead to the build-up of fatty deposits in the arteries.

However, the study found that every 10 minutes of inactivity can increase your risk of heart disease. It also increases your risk of all-cause mortality by 5.6%. Similarly, every additional 10 minutes of physical activity reduces your risk of death by 6.5%.

Low levels of physical activity (PA) and high levels of sedentary time (SLT) are common among older adults, and lack of PA is a risk factor for cardiovascular disease (CVD). There is a lack of knowledge about the association between accelerometer-measured PA, ST, and CVD risk in older adults. This study examines the association between accelerometer-measured PA and ST with cardiovascular risk, measured using the Framingham Risk Score (FRS), and all-cause mortality in older adults.

For the study, the team looked at data from 660 older adults with a mean age of 69 years. Their physical activity and sedentary time were measured using wrist-worn accelerometers for two weeks.
