title: The factor harmful to the quality of human life--shift-work.
abstract: The system of human activity, which is established by genetics and regulated by outer and inner factors, is associated with many characteristics which maintain the body in the best condition and ensure appropriate life quality.
  
  
  OBJECTIVE
  To evaluate of life quality among male shift-workers.
  
  
  METHODS
  Research based on a self-devised questionnaire, conducted among 700 shift-workers, followed by statistical analysis of the results.
  
  
  RESULTS
  Nearly a half of respondents (43.00%) reported that shift-work influences the quality of their family life. Remarkably, such an opinion was often stated by people with children (46.01%) p<0.05, the divorced (58.22%), married people (44.74%) and bachelors (25.33%), respectively. Fathers usually indicated lack of contact with their family as well as irregular consumption of meals (66.91%). Almost every third respondent noted that their shift type of work negatively influence their sexual life (31.14%).
  
  
  CONCLUSIONS
  It was shown that shift-work negatively influences the respondents' life quality in the form of deterioration of the quality of family life; the respondents, regardless of marital status, age and having children, most often complained about the lack of contact with the family and irregular eating with them; negative influence on sexual life, which was the case in one-third of respondents. In order to encourage healthy behaviour and increase the quality of life of people performing shift-work, training and programmes should be introduced. These would help shift- workers to adjust their work time to their family and social life.
