Worldwide, we estimate that physical inactivity is responsible for between 6% and 10% of the major NCDs of CHD, type 2 diabetes, and breast and colon cancers. And, this unhealthy behaviour is responsible for 9% of premature mortality, or >5.3 of the 57 million deaths in 2008. By eliminating physical inactivity, life expectancy of the world’s population may be expected to increase by 0.68 years. This makes inactivity comparable to the established risk factors of smoking and obesity, discussed below. It is important to interpret the added years of life correctly: they appear modest because they represent gains in the whole population (comprising inactive and active persons), not among inactive persons who become active. Because all the gain accrues to those who move from inactive to active, the increase in life expectancy among the inactive alone is greater. For perspective, other research conducted in the United States estimated that inactive persons would gain 1.3–3.7 added years from age 50 by becoming active. And, among East Asians, life expectancy from age 30 among the active was 2.6–4.2 years greater, compared with inactive persons.”
- “Noncommunicable diseases (NCDs) kill 41 million people each year, equivalent to 71% of all deaths globally.
- Each year, 15 million people die from a NCD between the ages of 30 and 69 years; over 85% of these “premature” deaths occur in low- and middle-income countries.
- Cardiovascular diseases account for most NCD deaths, or 17.9 million people annually, followed by cancers (9.0 million), respiratory diseases (3.9million), and diabetes (1.6 million).
- These 4 groups of diseases account for over 80% of all premature NCD deaths.
- Tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets all increase the risk of dying from a NCD.
- Detection, screening and treatment of NCDs, as well as palliative care, are key components of the response to NCDs.
Modifiable behavioural risk factors
Modifiable behaviours, such as tobacco use, physical inactivity, unhealthy diet and the harmful use of alcohol, all increase the risk of NCDs.
- Tobacco accounts for over 7.2 million deaths every year (including from the effects of exposure to second-hand smoke), and is projected to increase markedly over the coming years.
- 4.1 million annual deaths have been attributed to excess salt/sodium intake.
- More than half of the 3.3 million annual deaths attributable to alcohol use are from NCDs, including cancer.
- 1.6 million deaths annually can be attributed to insufficient physical activity.”
