Abstract :
Background: Shift workers may be exposed to fatigue and mental disorders due
to various work-related risk factors. This study evaluated the impact of demographic
characteristics on fatigue and mental disorders among 12-hour shift
workers in petrochemical industries.
Methods: This study was conducted among 290 shift workers of Pardis Petrochemical
Company in Iran. Data were collected using a general questionnaire for
the demographic characteristic as well as multidimensional fatigue inventory
(MFI-20) and general health questionnaire (GHQ-28).
Results: Married workers were less likely to suffer from reduced activity levels
(P < 0.027), depression (P < 0.032) and mental disorders (P < 0.040). Social dysfunction
score (P < 0.029) and mental disorders (P < 0.048) decreased with shift
work experience. Shift workers with non-academic education less likely to suffer
from reduced activity levels (P < 0.000) and mental fatigue (P < 0.028).
Conclusion: Despite the significant difference between the variables, this study
showed a weak effect of individual and occupational demographic characteristics
on fatigue and mental disorders.
