All assessments of the quality of work life occurred through the questionnaire QVS-80. Data were analyzed through descriptive statistics, the Z test and Cronbach's alpha test. Results: The main factors that interfered in the quality of life were: physical activity focused on aesthetics, physical fitness, smoking, physical activity recommended by a doctor, sitting time, family life, sleep quality, income. Comparing national data to the present study for all chronic diseases self-reported, statistically significant differences were observed.
