The impact of different shift work schedules on the levels of anxiety and stress in workers in a petrochemicals company

Abstract

This study evaluated anxiety and stress in workers under different shift work conditions. The sample comprised 239 workers, with an average age of 42.6, standard deviation = 5.7 years, divided into fixed daytime working (n=52) and different working shifts (n=187). Documentation: Free and informed consent form; ID's; State-Trait Anxiety Inventory; Lipp's Stress Symptom Inventory for Adults. We used the t-test for independent samples, ANOVA, Pearson's correlation and the two-sample Comparison of proportions Test. Results showed that shift workers had higher State-Trait Anxiety scores than fixed daytime workers (t=-4.994; p=0.0001; t=-2.816; p=0.005, respectively). Both samples exhibited stress, but there were no statistically significant differences between the groups (t=-1.052; p=0.294). Shift work schedules caused more situational and dispositional anxiety, but did not significantly increase stress levels when compared to fixed daytime working.

O Impacto do Trabalho por Turnos no Sono e Saúde Psíquica

“…28 A incidência de stress e da ansiedade conheceu um aumento drástico no estilo de vida urbano do último século. 30 Neste caso, o trabalho por turnos (como parte de uma sociedade de 24 horas) pode contribuir para esta realidade, facilitando uma resposta pouco adaptativa ao stress. Neste seguimento, na presença de alterações circadianas importantes, verificamos a existência de uma resposta fisiológica semelhante àquela encontrada em indivíduos expostos a situações de stress crónico, com um aumento da resposta à glicose oral, aumento dos níveis plasmáticos de cortisol e um aumento da atividade do sistema nervoso simpático.…”

Hubungan lama mengemudi dan tingkat stres pada supir bus antar kota

“…(13,14) Responden dengan shift kerja >12jam (60.8%) cenderung memiliki keluhan stres lebih berat dibandingkan responden dengan shift kerja pagi atau malam karena beban kerjanya yang berat. Hal ini sesuai dengan penelitian De Almondes KM (15) et al Vierdelina N (16) yang mengungkapkan bahwa kerja shift dapat mempengaruhi kinerja karyawan dalam berbagai cara, contohnya adanya gangguan pada irama tubuh (circadian rhythms), yang dapat menimbulkan kerugian terhadap kemampuan fisik dan mental pekerja shift. Jika pekerja tidak mendapatkan tidur yang cukup maka kinerjanya dapat menjadi buruk.…”

Does Shiftwork Impact Cognitive Performance? Findings from the Canadian Longitudinal Study on Aging (CLSA)

“…Shiftwork is defined as non-standard work hours occurring in the hours before 7:00 a.m. or after 6:00 p.m. [ 1 ], and has become more prevalent worldwide [ 2 ], with specific industries and occupations highly dependent on the shift system [ 1 , 3 ]. Shiftwork is associated with sleep loss [ 4 ] and the development of numerous health conditions which may be a product of disrupted circadian rhythms due to abnormal work hours [ 5 ].…”
