Prisons; Temporomandibular Joint Dysfunction Syndrome; Occupational Health
BACKGROUND: Temporomandibular disorder (TMD) is a group of musculoskeletal disorders of multifactorial origin that affects the temporomandibular joint. Knowing the occurrence of TMD in workers and investigating the occupational factors associated with this condition can be relevant in workers in the safety area, who are supposedly more exposed to psychosocial stressors at work. OBJECTIVE: To investigate the prevalence of TMD in correctional officers (CO) and its association with psychosocial aspects of work, in general, and related to work in prison, in particular, besides with sociodemographic characteristics and lifestyle. METHODS: Cross-sectional study with 401 correctional officers from Salvador, Bahia, Brazil, who answered a self-administered questionnaire. The outcome variable was TMD, assessed by the Fonseca Anamnesis Index. Psychosocial aspects were measured using the Job Content Questionnaire (JCQ) and specific questions about the work of COs. Cox's multivariate regression provided adjusted prevalence ratios. The independent variables inserted in the blocks were the dimensions psychological demand and job control, sociodemographic and lifestyle characteristics, psychosocial aspects of COs work and social support, from colleagues and supervisors. RESULTS: The prevalence of TMD was 35.4%. After multivariate analysis, the variables associated with TMD were: high psychological demand (PR Adjust = 1.37), female gender (PR Adjust = 2.17), not practicing leisure activity (PR Adjust = 2.77), having another occupation (PR Adjust = 1.60), experiencing a situation of fear due to contact with factions in the workplace (PR Adjust = 1.59) and low social support from co-workers (PR Adjust = 1.42) and supervisor (PR Adjust = 1.45). CONCLUSION: Psychosocial aspects at work, including high psychological demand and low social support from colleagues and supervisor, in addition to fear of contact with factions, were independently associated with TMD. Work interventions should be implemented that expand the support of supervisors and promote networks of solidarity among co-workers. In addition, fostering leisure practices can contribute to the protection of workers' health. Work management in the prison complex and preventive interventions must be sensitive to the gender inequalities at work.
