Sickness Absence at Work and Supporting Being Present At Work, Among Employees Working Different Shifts in the Forest Industry

2015

Objective: Shift work has negative effects on employee overall health, including sleep disorder, depressive symptoms, and cardiovascular and metabolic diseases. The association between shift work and the prevalence of sickness absence has been less studied. This study investigated sickness absence among employees working different work shift schedules in the forest industry. Method: This descriptive cross-sectional study used employee (N=636) data from forest industry sick-leave registers. The study population (n=280; women n=90 and men=189) worked five different shifts. Each of the five shifts was analyzed separately for sickness absence rate and the results were compared using independent…

The Effects of Individual Characteristics of the Naval Personnel on Sleepiness and Stress during Two Different Watchkeeping Schedules

2022

Background: Naval service can have a significant impact on the wellbeing of seafarers, and the operation of warships is highly dependent on the personnel on board. Nevertheless, there is a lack of knowledge concerning the impact of seafarers’ individual characteristics on their wellbeing in a naval environment. Therefore, the aim of this study was to investigate individual characteristics of the naval personnel that may be associated with the amount of sleepiness, fatigue and stress responses experienced during shift work and irregular working hours in a naval environment. Methods: The study took place on a Finnish Defence Forces’ Navy missile patrol boat on which 18 crewmembers served as s…

Accumulation of sleep loss among shift-working truck drivers.

2021

Sleep loss is known to contribute to road traffic accidents. Professional drivers are vulnerable to curtailment of sleep due to long driving bouts and shift work. To fill in the gap in the literature related to the buildup of sleep loss in irregular shift systems, we recorded the sleep and working hours of 47 shift-working long-haul truck drivers during a two-week period. Sleep (time in bed) was verified by actigraphy and sleep logs. Sleepiness was measured using the Karolinska Sleepiness Scale (KSS). Individual sleep need was based on self-assessments. We examined the accumulated sleep versus self-reported sleep need across the study period, using midnights as points of observation, and th…

Hair Cortisol Concentration as a Biomarker of Sleep Quality and Related Disorders

2021

Cortisol is the end product of the hypothalamic-pituitary-adrenal (HPA) axis, and its production is increased mainly in stressful situations or in chronic disorders accompanied by stress enhancement. Altered cortisol concentrations have been reported in a number of neuropsychiatric diseases and sleep disorders. Cortisol concentrations have been measured using several methods, and in several matrixes, such as blood, saliva, and urine. However, lately, hair cortisol, for several reasons, has emerged as a promising biomarker of long-term retrospective HPA activation. Several experimental approaches for cortisol measurement with the corresponding concentration reference ranges and a summary of …

Hoitoalan esimiesten keinot ja haasteet epätyypillistä työaikaa tekevien alaistensa hyvinvoinnin edistämisessä

2016

TIIVISTELMÄ Miika Klinga & Ville Leskinen (2016). Hoitoalan esimiesten keinot ja haasteet epätyypillistä työaikaa tekevien alaistensa hyvinvoinnin edistämisessä. Terveystieteiden laitos, Jyväskylän yliopisto, terveyskasvatuksen pro gradu-tutkielma, 63 s., 4 liitettä. Tutkimuksen tarkoituksena oli selvittää kahdessa eri sairaalaorganisaatiossa työskentelevien hoitoalan esimiesten kokemuksia ja näkemyksiä epätyypillisen työajan asettamista haasteista ja keinoista, joita heillä on käytössään vuorotyötä tekevien alaistensa hyvinvoinnin edistämisessä. Lisäksi tutkittiin millaisia uusia keinoja esimiehet haluaisivat ottaa käyttöönsä alaistensa hyvinvointia edistämään. Tutkimus toteutettiin laadul…

Self-reported reasons for on-duty sleepiness among commercial airline pilots

2021

Experimental and epidemiological research has shown that human sleepiness is determined especially by the circadian and homeostatic processes. The present field study examined which work-related factors airline pilots perceive as causing on-duty sleepiness during short-haul and long-haul flights. In addition, the association between the perceived reasons for sleepiness and actual sleepiness levels was examined, as well as the association between reporting inadequate sleep causing sleepiness and actual sleep-wake history. The study sample consisted of 29 long-haul (LH) pilots, 28 short-haul (SH) pilots, and 29 mixed fleet pilots (flying both SH and LH flights), each of whom participated in a…

EFFECTS OF SHIFT WORK ON CARDIOVASCULAR ACTIVITY, SERUM CORTISOL AND WHITE BLOOD CELLS COUNT IN A GROUP OF ITALIAN FISHERMEN

2012

We analyzed the effects of working activity and working shifts on the circadian rhythmicity and circadian phase relations of serum cortisol level, white blood cells count, resting heart rate and systolic/diastolic blood pressure in a group of italian fishermen. We observed a shift-induced displacement of cortisol secretion and a modification in leukocyte count. Moreover, systolic/diastolic blood pressure and resting heart rate were markedly influenced by the night shift, whereas no appreciable changes were observed after the morning and afternoon shifts, compared to pre-working values. These data suggest that the human circadian system is greatly influenced by shift work, and serum cortisol…

Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting

2019

Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…

Working hours – tracking the current and future trends

2021

It is important to track the trends of future working hours, since working hours have strong associations to everyday life and work-life interaction, but also to health. In this paper we aim to track the current and future trends in working hours. We discuss the trends through the key dimensions of working hours: the length, timing, tempo and autonomy. We also consider the role of current trends of spatial changes of work. Changes in working time patterns are fostered by several driving factors: globalization and business restructuring challenging the current work organizations, new information technologies, demographic and climate change and the current and future pandemics. The past and c…
