Shift work and the risk of cardiovascular disease among workers in cocoa processing company, Tema

Abstract

ObjectiveShift work has been implicated in cardiovascular disease (CVD), a major cause of death globally. The aim of this study was to evaluate the risk of developing CVD in shift work.DesignA cross-sectional study involving secondary analysis of shift and non-shift work from an industry in Ghana.ParticipantsTwo hundred (113 shift and 87 non-shift) consecutive workers who consented were recruited into the study. A structured questionnaire was administered to deduce information on participant’s age, alcohol consumption pattern, smoking habits, history of diabetes, stroke and hypertension.ResultsShift workers were found to be associated with higher body mass index (26.9 ± 4.6 vs 25.2 ± 3.3, p = 0.013); fasting blood glucose (5.9 ± 1.8 vs 5.3 ± 0.8, p ≤ 0.0001); glycated haemoglobin (4.9 ± 0.9 vs 4.2 ± 0.8, p ≤ 0.0001); high sensitivity C-reactive protein (2.5 ± 1.1 vs 1.8 ± 1.1, p < 0.0001); total cholesterol (5.9 ± 1.3 vs 5.2 ± 1.7, p = 0.002); triglycerides (1.3 ± 0.8 vs 1.1 ± 0.6, p = 0.015) and LDL cholesterol (3.6 ± 0.9 vs 3.2 ± 1.3, p = 0.04) than controls. Shift work however, had no associations with HDL-cholesterol.ConclusionIt can be concluded that shift work is associated with risk factors of CVD.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1750-3) contains supplementary material, which is available to authorized users.

The influence of shift work on the occurrence of hypertension, ischemic heart disease and dyslipidemia from the perspective of mine shift workers

“…In our study, blood pressure was higher than 139/89 mmHg in one in four workers, with hypertension significantly more frequent among men aged 41-50 (31.9%). In the other studies, elevated cholesterol levels among shift workers were observed and an elevated triglyceride level was reported to be associated with shift work [2,13]. This may be due to reduced sleep duration associated with the shift work.…”

“…This observation could be due to more stressful jobs being given to the younger workers and leaving the less stressful jobs for the older workers. Continued shift work could also lead to adaptation of biological rhythms that do not promote hypertension [2]. It has been reported that shift work is associated with an increased prevalence of hypertension, but data are inconclusive [12].…”

“…This may be due to reduced sleep duration associated with the shift work. reduced sleep has been linked to disruption of biological rhythms and dyslipidemia [2,14]. Different studies have confirmed a direct relationship between shift work and cardiac disease and dyslipidemia.…”

“…About 20% of workers in Europe are employed as shift workers, involving night work and extended hours [1,2]. Shift workers have been demonstrated to be at the increased risk of cardiovascular disease [3,4].…”

Concordância entre cintura hipertrigliceridêmica e cintura estatura hipertrigliceridêmica em trabalhadores em turnos alternantes

“…11 Estudo mostra que trabalhadores do turno apresentam prevalência mais alta de fatores de risco para doenças cardiovasculares, como aumento da glicemia, aumento da pressão arterial, perfis lipídicos alterados e obesidade, quando comparados aos trabalhadores do turno diurno. 12 O trabalho em turnos inclui qualquer arranjo do horário de trabalho diário além das horas diurnas padrão (7h/8h-17h/18h), tais como turnos noturnos e alternantes (turnos de trabalho em horários alternados). 13 No turno alternante, os trabalhadores se revezam trabalhando em todos os turnos de um sistema específico de jornada de trabalho.…”
