In Switzerland, the number of years of life lost due to a non-communicable disease (NCD) per 100 000 population has continued to fall since 1995. In 1995, 2265 years overall were lost to NCD, whereas in 2017 this number was 1206. In 2017, the burden of years lost (1'427) to men is considerably greater than those lost to women (983 years).
The continuous decline can also be seen when the years of life lost are broken down by disease: For example, the years of life lost due to cardio-vascular disease have fallen from 610 (1995) to 246 (2017) per 100 000 population and for cancer, figures have fallen from 1'076 to 640 years over the same time period.
This indicator is part of the Monitoring System Addiction and NCD (MonAM) of the Federal Office of Public Health (FOPH).
A person’s years of potential life lost due to NCD show how much longer this person would have lived had they not died before the end of their 70th year due to a non-communicable disease (NCD):
Early deaths are calculated on the basis of deaths within the population. With a selected age limit of 70, a death at the age of 10 means 60 years of potential life lost, death at the age of 65 means 5 years of potential life lost.
A major objective of the NCD strategy is to fight frequently occurring and chronic diseases such as cardio-vascular diseases, cancer, diabetes, respiratory disease and musculoskeletal diseases. It aims to reduce the burden of disease in the population and prevent early death. The number of years of life lost provide direct and quantifiable information on the trend in this number.
“Years of potential life lost (YPLL)” is an internationally recognised indicator.
The indicator shows the number of years of potential life lost per 100 000 population (permanent resident population) for deaths occurring between birth and the age of 70. Data are standardised according to the age structure of the European standard population in 2010 (Eurostat 2013). To calculate the YPLL, the deaths in each age group are added together and weighted by the remaining years until a selected age limit. This age limit has been set at 70 for reasons of international comparability (WHO).
The following non-communicable diseases (NCD) are usually taken into consideration for the analysis:
- Diseases of the circulatory system (I00- I99)
- All cancers (C00-C97)
- Diabetes mellitus (E10-E14)
- Diseases of the respiratory system (J30-J98)
- Diseases of the liver (K70 and K74)
Diseases are classified as NCD in accordance with the classification outlined in the study by Lozano Rafael, Mohsen Naghavi, Kyle Foreman, Stephen Lim, Kenji Shibuya et al. (2012), which analyses the “global burden of disease”.
