text: In a similar way,**the levels of ergonomic risks**are related with the sectoral structure of a country, 
  determining the type of occupations and work tasks. EU-OSHA provided a detailed analysis of the 
  prevalence of musculoskeletal disorders (MSDs) and the related risk factors in several studies on 
  musculoskeletal diseases, for example, ‘Work-related musculoskeletal disorders: why are they still so 
  prevalent?’58 
  
  An example of the**interrelation between sectors and risks is the connection**between the sector 
  aggregate ‘Trade, transport, food/accommodation and recreation activities’ and three major indicators 
  of ergonomic burden, that is, ‘Painful, tiring positions’, ‘Repetitive hand or arm movements’, and 
  ‘Carrying or moving heavy loads’. 
  
  Seven countries have a share of employees in this sector of more than 30% (Cyprus, Greece, Spain, 
  Malta, Bulgaria, Croatia and Latvia), and many of them are present in two or three lists of countries with 
  the highest number of responses regarding the indicators.
