Sleep disturbances and related occupational diseases in Ukrainian firefighters
Sleep deprivation is one of the main professionally determined factors for firefighters which can decrease their executive functioning and contribute to an array of health problems in them, including cardiovascular disease, diabetes, and depression mood disorders. The aim of this research is to gather preliminary data regarding the health of Ukrainian, with a focus on sleep quality indicators. Sleep-deprived participants in our research study were identified using such questionnaires as PSQI, ISI, ESS, SSS, FSS, and BQSA. Statistical processing of the data was carried out with the aid of Fisher's exact test, a statistical tool which is widely used in medical researches when the expected numbers are small. The obtained results confirm the presence of certain regularities. First, typical for the firefighting profession sleep disorders were detected among workers of operatively rescue service of Kropyvnitskiy city: including daytime fatigue, low sleep quality, insomnia, apnea, restless leg syndrome, low alertness, daytime sleepiness. Secondly, individuals suffering from sleep deprivation are at a higher risk for developing certain cardiovascular and metabolic diseases, depressive disorders, including increased impulsivity and overall lack of executive functioning. Thirdly, the importance of early detection and treatment for sleep disorders as a protective measure against the development of the aforementioned diseases has been stressed in our study. Sleep hygiene education should be provided to Ukrainian firefighters. It could influence them to make better choices related to their sleep, which would subsequently impact other areas of their health and wellbeing. Annual research studies concerning firefighters' sleep quality should be conducted in Ukraine on a regular basis with the aim to accumulate relevant statistics on the topic under consideration.
