Abstract
Maiņu darbu veic nodarbinātība, kas paredzēta pakalpojumu sniegšanai visu diennakts – 24 stundu laikā katru dienu un katru nedēļu. Maiņu darba prakse ir sadalīta maiņās, dienas maiņās un nakts maiņās, kas strādā atsevišķi vai kopā, ko sauc par rotējošu maiņu. Gan medicīnā, gan epidemioloģijā maiņu darbs ir saistīts ar homeostāzes izmaiņām, jo tas izraisa miega/nomoda cikla līdzsvara traucējumus, ietekmējot kortizola līmeni, kas ir galvenais cirkādes ritma regulators. Ietekme ir kortizola dienas sekrēcijas nelīdzsvarotība, kas saistīta ar vielmaiņas traucējumiem, miega traucējumiem, garastāvokļa traucējumiem un citiem ar veselību saistītiem traucējumiem.
Šī pētījuma mērķis ir uzsvērt maiņas darba ietekmi uz kortizola līmeni, galvenokārt izmantojot siekalu kortizolu kā galveno biomarķieri. Tiek parādīta arī saistītā ietekme kā miega traucējumi, ar darbu saistīts stress un nogurums. Profesionālās grupas kā ugunsdzēsēji, policisti, ārsti, medmāsas, neatliekamās palīdzības izsaukuma dispečeri un neatliekamās palīdzības sniedzēji ir vienas no pētītajām profesijām, kurās lieliski redzama maiņas darba un kortizola stresu viņu iedarbības uz vidi dēļ.
Līdzīga tendence, kas atrasta pētītajos materiālos, bija izmaiņas kortizola pamošanās reakcijā un kopējā kortizola sekrēcijā dienas laikā, ko dēvē par kortizola AUC (laukumu zem līknes). Visbeidzot, pateicoties līdzīgiem kortizola maiņas modeļiem maiņu darbā, mēs varam secināt, ka ir kortizola disregulācija, ko ietekmē sirdsdarbības ritma traucējumi; šo disregulāciju vēl vairāk ietekmē nodarbošanās, vecums, fizioloģiskā pielāgošanās miega zudumam un maiņas cikla ilgums, kas ietekmē atveseļošanos un pielāgošanos.
Shift work is carried out by employments designed to provide service across all the 24 hours of the day each day and each week. The practise of shift work is divided into shifts, day shifts and night shifts either worked separately or together, called rotating shift. In both medicine and epidemiology shift work is associated with the alteration of the homeostasis as it causes imbalance in the sleep/wake cycle affecting the cortisol level which is the main regulator of circardian rhythm. The effect is imbalance in the diurnal secretion of cortisol which is associated with metabolic disorders, sleep disorder, mood disturbances and other health related interferences. The aim of this literature review was to highlight the impact of shift work on cortisol levels; pursuing this study revieweing mainly articles relevant to this topic. Associated impacts such as sleep disorders, occupational related stress, and fatigue will be presented as well. Occupational groups as firefighters, policemen, physicians, nurses, emergency call dispatchers and emerengy care providers are among the studied entities, giving a great reflection on shift work and stress on cortisol due to their environmental exposure. A similar trend found in studied materials was the changes in the cortisol awakening response and the overall cortisol secretion during the day refered to as the cortisol AUC (area under the curve). Finally due to the similar patterns of cortisol change in shift work we can conclude that there is a cortisol dysregulation affected by circardian rhythm disruption; this dysregulation is further affected by occupation, age, physiological adaptation to sleep loss and the length of the shift cycle which infleunces recovery and adaptation.
