IntroductionEvents generated by exposure to job stressors together with individual characteristics bring about various health afflictions which come to bear on the development of burnout syndrome. ObjectiveTo analyze the variables age, social support and self-esteem in regard to the development of burnout syndrome. MethodsThe population was composed of 875 traffic agents. A questionnaire on socio-demographic and occupational data was applied, together with the Maslach Burnout Inventory Scale (MBI-HSS), the Amended Social Resources Inventory of Diaz Veiga, and the IGA-2000 scale on self-esteem. Results802 (91.6%) traffic agents were men and 73 (8.4%) were women. The minimum age was 20 years and the maximum was 84 years (one individual each). The prevalence of burnout syndrome was of 47.8% for the age group under 42 years and 65.9% for those over 43 years. As for objective social support, the prevalence for the larger group of ages 43 years or more was 16.1%, while subjective support was 16.7%. The prevalence of the variable self-esteem was 7,9% in patients over 43 years old. The inferential analysis showed several significant associations between age and the study variables. ConclusionsIncreased age is a risk factor in the development of burnout syndrome, as is having poor or inadequate social support and low self-esteem.
