text: The impact of work — as one essential element of the socioeconomic status — on health was the subject 
  of numerous academic studies, often performed as specific case studies. The authors of an overview 
  study on ‘Cross-country inequality in the EU’ summarise (more references in the original text): 
  
  *‘Occupational grade and labour market status are among the factors most often studied in relation to*
  *health and mortality. Occupational grade has been found to be associated with self-rated health, mental*
  *and physical health, such as the presence of long-standing illness and a number of diseases. Lower*
  *occupation might affect health through poor working conditions, such as the higher exposure to*
  *occupational hazards and toxic compounds, health-damaging behaviours and psychosocial stress.*
  *Work-based stress combined with a lack of autonomy over one’s work are believed to be the*
  *psychosocial factors that can cause physiological changes, such as increased risk of cardiovascular*
  *diseases and reduced immune system response. It has been shown that the gaps in mortality between*
  *different occupational grades persist in old age and tend to widen with age.*202 
  
  Eurostat provides in the LFS**2020 Ad hoc module**on ‘Accidents at work and other work-related health 
  problems’ a rough overview on such relations, with some specification, for example, for sectors, 
  attainment levels, professional status, size of enterprise or occupation. 203 The differences between four 
  aggregated occupational groups and work-related health problems is shown in the next table.
