text: A fundamental element of these disease statistics are the DALYs (DALY = lost life years due to disability 
  or in other words:**One DALY is one lost year of healthy life**).207 These DALYs are a combined value 
  of the mortality rate YLL (Years of Life Lost due to premature mortality) and the YLD (Years Lived with 
  Disability). DALYs are regarded as a comprehensive and comparable method to measure the health of 
  a population. 208 
  
  Based on this framework, the Institute for Health Metrics and Evaluation (IHME) provides interactive 
  statistical data of the trends and status of risk factors and outcomes (Death and DALYs). These data 
  are constantly updated and visualised; the risk factors are: environmental risk, occupational risks (e.g. 
  occupational ergonomic factors), behavioural risks (e.g. dietary) and metabolic risks (e.g. high systolic 
  blood pressure).209
