The courses of objective physical activity and the association with sleepiness during a 2-week-on/2-week-off offshore shift rotation: an observational repeated-measures study

by Admin1 | Apr 17, 2021

Background Offshore workers are assumed to have poor health behaviours, but no studies have yet examined physical activity (PA) during a full offshore shift rotation period, including both work and at home periods. Furthermore, the relationship of PA with sleepiness,...

Time-of-day and days-on-shift predict increased fatigue over two-week offshore day-shifts

by Admin1 | Mar 20, 2019

Objectives The purpose of this study was to investigate the accumulation of fatigue over a two-week offshore period. In particular, the effects of (1) time-of-day and days-on-shift as well as (2) acute and chronic sleep loss on the rate at which fatigue accumulates...

Examining courses of sleep quality and sleepiness in full 2 weeks on/2 weeks off offshore day shift rotations

by Admin1 | May 16, 2018

To better understand sleep quality and sleepiness problems offshore, we examined courses of sleep quality and sleepiness in full 2-weeks on/2-weeks off offshore day shift rotations by comparing pre-offshore (1 week), offshore (2 weeks) and post-offshore (1 week) work...

Investigating daily fatigue scores during two-week offshore day shifts

by Admin1 | Apr 27, 2018

Objectives This study examined daily scores of fatigue and circadian rhythm markers over two-week offshore day shift periods. Methods A prospective cohort study among N = 60 offshore day-shift workers working two-week offshore shifts was conducted. Offshore day shifts...

O35-4 Course of sleepiness and sleep parameters in 2-2 offshore rotations

by Admin1 | Sep 1, 2016

Introduction Sleep and fatigue problems are among the most common health and safety concerns in the offshore oil and gas industry. To understand sleep and fatigue problems offshore, we examined the course of sleepiness and sleep parameters across 2-2 offshore...
