Objective: To assess job stress, burnout, and job satisfaction in patients with obstructive sleep apnea syn-
drome (OSAS).
Methods: A total of 182 patients with OSAS and 71 healthy individuals completed the Job Content Ques-
tionnaire, the Maslach Burnout Inventory – General Survey, the Index of Job Satisfaction, the Epworth
Sleepiness Scale, and the Pittsburgh Sleep Quality Index. All participants were assessed with full-night
polysomnography.
Results: Survey scores of patients diagnosed with OSAS only differed from those of the control group in
the emotional exhaustion dimension (P = 0.015). According to a multivariate analysis, the apnea–
hypopnea index (AHI) was only correlated with perceived support at work (β coefficient = 0.142; P = 0.048).
Associations were found between subjective sleep quality, perceived support from coworkers, and su-
pervisors (β = 0.157; P = 0.025), psychological demands (β = 0.226; P = 0.001), emotional exhaustion (β = 0,405;
P = 0.000), and cynicism (β = 0.224; P = 0.002). The study also revealed associations between excessive
daytime sleepiness and the burnout dimensions emotional exhaustion (β = 0.232; P = 0.000) and cyni-
cism (β = 0.139; P = 0.048).
Conclusion: Objective parameters of OSAS such as the AHI seem to have limited influence on the psy-
chosocial aspects of the occupational life of patients with OSAS. There is evidence of significant asso-
ciations between the subjective symptoms of the disease, such as daytime sleepiness, subjective sleep
quality, job stress, and burnout.

1. Introduction
Obstructive sleep apnea syndrome (OSAS) is a chronic breath-
ing disorder characterized by repeated episodes of limited air flow
during individuals’ sleep that lead to a decrease in nocturnal oxygen
saturation and micro-awakenings [1]. In western societies, this syn-
drome has a prevalence of 24% in middle-aged men and 9% in
middle-aged women [2], and is associated with the development
of hypertension, cardiovascular and cerebrovascular disorders and
abnormalities in glucose metabolism [3].
OSAS has a variety of symptoms such as snoring, apneas re-
ported by the bed partner, frequent awakenings and sleep agita-
tion and fragmentation. Patients with OSAS experience fatigue and
the feeling of having had non-restorative sleep. They often report
morning headaches, mood changes (e.g. depression and anxiety
[4,5]), cognitive difficulties (e.g. loss of short-term memory and
longer reaction times [6,7]), and sexual problems [8].
Most of the functional difficulties reported by patients with OSAS
are secondary to excessive daytime sleepiness (EDS), which is the
symptom with the greatest impact of patients’ everyday life [9]. Due
to EDS and its above-mentioned repercussions on patients’ phys-
ical and cognitive function, such patients have a greater number of
traffic accidents [10] and accidents at the workplace [11]. People
diagnosed with OSAS or who exhibit symptoms of this disease have
been found to have higher levels of absenteeism and work disabil-
ity compared with controls [12], and EDS is often the most impor-
tant factor determining the high prevalence of sick leave and the
productivity decrease observed in such patients [13–15].
Some authors have explored the relationship between sleep dis-
orders, job stress, and burnout syndrome. Workers who have a sleep
disorder such as insomnia or OSAS have reported higher job stress
compared with that of healthy individuals [16].A

argue that sleep may be involved in the development of burnout,
as individuals with symptoms of burnout also report sleep
fragmentation. People with high levels of burnout syndrome are
