LATAR BELAKANGPekerja bergilir (shift workers) banyak dijumpai pada masyarakat industri dan mempunyai efek yang negatif terhadap kualitas tidur. Excessive daytime sleepiness (EDS) adalah gejala dari gangguan tidur berupa rasa kantuk pada siang hari yang berlebihan hingga mengganggu aktivitas. Gejala ini dapat menimbulkan dampak merugikan bagi pekerja dan perusahaan. Kualitas tidur, kerja shift, gaya hidup, usia dan jenis kelamin merupakan faktor risiko dari EDS. Seorang pekerja bergilir yang mengalami EDS memiliki risiko kecelakaan kerja yang tinggi. Penelitian ini dilakukan dengan tujuan untuk menentukan hubungan antara kualitas tidur dan EDS pada pekerja bergilir. METODEStudi ini menggunakan desain cross-sectional dengan jumlah subjek penelitian sebanyak 57 pekerja bergilir. Pengumpulan data mengenai usia dan jenis kelamin dilakukan dengan menggunakan kuesioner. Kualitas tidur diukur dengan kuesioner Pittsburgh sleep quality index (PSQI) dan Excessive daytime sleepiness (EDS) diukur dengan Epworth sleepiness scale (ESS). Data dianalisis menggunakan uji korelasi Spearman dan uji Mann Whitney. HASILHasil uji normalitas menunjukkan data yang dikumpulkan tidak tersebar secara normal. Nilai median subjek pekerja besarnya 27 tahun dan sebagian besar subjek adalah laki-laki sebanyak 44 (77.1%) orang.Tidak didapatkan perbedaan yang bermakna antara jenis kelamin dan EDS (p=0.396). Didapatkan hubungan yang sedang dan bermakna antara kualitas tidur dan EDS (r=0.545; 0=0.000). Usia subjek tidak berhubungan secara bermakna dengan EDS (r=0.124; p=0.359). KESIMPULANPenelitian ini menunjukkan hubungan bermakna antara kualitas tidur dan excessive daytime sleepiness pada pekerja, tetapi tidak terdapat perbedaan nilai median EDS antara laki-laki dan perempuan.

Sleep disorders continue to rise and have been estimated to affect around half of the global population. Poor sleep quality and insomnia are also linked to various health issues in different populations. The Pittsburgh Sleep Quality Index (PSQI) is one of the most commonly used tool to assess sleep quality. It has been tested in various clinical and non-clinical settings and populations but mostly in developed world. Literature is limited from Arab region and further scarcity of studies is observed among health providers from the region. This study aimed to assess the construct validity and factor structure of PSQI among physicians in Jeddah, Kingdom of Saudi Arabia. This cross-sectional study used the PSQI tool with 19 items and 7 components on 330 physicians working in Jeddah. Data was entered and analyzed in IBM SPSS and AMOS version 22. Cronbach alpha was 0.745. Construct validity showed satisfactory results. Exploration of factor structure with Confirmatory factor analysis (CFA) showed 1-factor model as better fit. Among three models, 3-factor model showed least fit indices. The study findings showed some similarities as well as differences to comparable studies using PSQI in other settings that requires further as well as continuous exploration of the dynamic issue in similar and diverse settings.

Relevance. Shift work was found to induce pathological processes due to desynchronization of human circadian biorhythms.Intention. To determine incidence of hemostasis disorders and their relation to labour nature in employees of EMERCOM of Russia.Methodology.There were examined 37 employees of EMERCOM of Russia aged 32–58 (42.0 ± 6.8) with work experience (12.0 ± 6.9) years, high level of psychosocial stress and different work schedules: day (n = 11), shift (n = 14), irregular working hours (n = 12). The level of professional stress was studied using a specially developed questionnaire and the night sleep – using Pittsburgh Sleep Quality Index (PSQI). Сortisol circadian dynamics was evaluated, hemostasis state was fully assessed.Results and Discussion.The questionnaire showed irregularity of work schedule, additional working hours, decreased leisure time and high intensity of work in all study groups. High incidence of arterial hypertension (44 %) was registered without constant antihypertensive therapy. Pittsburgh Sleep Quality Index (PSQI) indicated sleep disorders among 24 (65 %) EMERCOM employees. Сortisol circadian dynamics test demonstrated increased level of the evening cortisol in 40 % of EMERCOM employees indicating widespread desynchronosis signs in the study group. Hemostatic system comprehensive assessment showed absence of considerable changes in thrombocytic component and a significant activation of plasma hemostasis according to the thrombodynamics assay. Hemostasis disorders were most expressed in the group with shift work and high psychosocial stress; they manifested in increased clots formation, spontaneous clots formation and increased VIII coagulation factor activity.Conclusion. The study confirmed the existing vision that chronic stress and desynchronosis change the hemostatic balance into chronic hypercoagulation state.

This study aimed to perform a subjective evaluation of the sleep quality of truck drivers in the extreme western region of Santa Catarina. For this purpose, a questionnaire was used to evaluate the participants' profile and two other questionnaires to measure the degree of sleepiness (Epworth Scale) and Pittsburgh sleep quality index. The sample consisted of 179 truck drivers, all of them male, aged between 21 and 65 years; 77.65% married and 22.34% single; 72.6% have children, with an average of two children per participant. As for the professional profile, 75.9% of the interviewees work as wage earners and 24.1% as freelancers. The type of route covered, in most cases, is long distance, representing 66%, and 34% being short distance routes. Regarding the educational level, 53.5% of the participants have elementary education; 42.4% high school and 3.9% were graduates. Overweight or obesity was identified in 59.80% of the interviewees. About sleep quality, 22.5% reported sleeping less than 5 hours daily; 35.1% from 5h to 6h; 29.0% from 6h to 7h; 12.8% sleep more than 7 hours. On the Epworth Sleepiness Scale, 67.0% presented no sleepiness; 27.3% presented mild degree of somnolence; 5.5% had moderate degree of somnolence. Regarding the Pittsburgh Sleep Quality Index, it was verified that 55.8% presented subjective poor sleep quality. The results suggested that lifestyle and poor habits can negatively influence the health of these professionals.

ObjectivesLong-haul truck drivers (TDs) may have lifestyles that promote cardiovascular disease (CVD), including diet, sleep and activity issues. Most studies conducted among truckers investigated the relationship between poor sleep and cardiometabolic health, but none assessed whether suspected obstructive sleep apnoea (OSA) and shortened sleep were associated with markers of cardiometabolic risk. We determined whether sleep disorders and circadian misalignment were associated with chronic inflammation and CVD risk in TDs from Southern Africa.MethodsParticipants were recruited at roadside wellness centres in Gauteng and Free State Provinces, South Africa. OSA risk was assessed using the Berlin Questionnaire, while sleep duration and sleep quality were assessed using items from the Pittsburgh Sleep Quality Index. Clinical information, neck circumference (NC), metabolic profile, elevated BP, HIV status and C-reactive protein (CRP) were collected. CVD risk was assessed using the Framingham Risk Score (FRS).ResultsOut of 575 participants aged on average 37.7 years, 17.2% were at OSA risk, 72.0% had elevated BP, 9.4% had HIV and 28.0% were obese. Mean sleep duration was 7.4±1.8 hours, and 49.6% reported working night shift at least once a week. Shortened sleep, OSA risk, age, body mass index, NC and years as full-time TD were associated with greater FRS independently of HIV status and night shift. Working night shift was associated with higher CRP levels in HIV+ compared with HIV− participants.ConclusionsCircadian misalignment in HIV, and OSA and short sleep duration in all truckers were associated with increased CVD risk. Truckers should be given careful attention in terms of health management and sleep education.

Palm Oil Mill PT. Surya Intisari Raya, Sei Lukut is a plantation company engaged in the commodity palm oil FFB (Fresh Fruit Bunches), with output in the form of CPO (Crude Palm Oil) and Palm Kernel (PK). There are 13 processing stations at PKS that have high noise levels, one of which is a sterilizer station which can disrupt operator psychology, namely Sleep Disturbance. In the field survey, it was found that operators experienced concentration problems such as drowsiness, and not all of them used ear protection in the form of earplugs/earmuffs. Therefore, it is necessary to identify the noise level at the sterilizer station and to analyze its effect on the operator's sleep quality using an observational analytic cross-sectional approach. Noise in the workplace was measured using a sound level meter and the sleep quality of workers was measured using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Based on the results of noise level measurements, 4 processes have noise above the Threshold Limit Value, namely Deaeration of 89.824 dB, Containment of 92.548 dB, Peak BlowDown by 2 of 96.45 dB, and Final of 102.77 dB. Based on the results of the Pittsburgh Sleep Quality Index (PSQI) questionnaire, 100% of Morning Shift and Night Shift workers have poor sleep quality. To overcome this problem, several suggestions were made, namely to carry out periodic health checks for operators, ensure that operators who are exposed to noise always wear an earplug/earmuff, and minimize exposure to noise above the NAB to operators by keeping noise points away from the operator's premises.

Euhydration remains a challenge in children due to lack of access and unpalatability of water and to other reasons. The purpose of this study was to determine if the availability/access to a beverage (Creative Roots®) influences hydration in children and, therefore, sleep quality and mood. Using a crossover investigation, 46 participants were randomly assigned to a control group (CON) or an intervention group and received Creative Roots® (INT) for two-week periods. We recorded daily first morning and afternoon urine color (Ucol), thirst perception, and bodyweight of the two groups. Participants reported to the lab once per week and provided first morning urine samples to assess Ucol, urine specific gravity (USG), and urine osmolality (Uosmo). Participants also completed the questionnaires Profile of Mood States-Adolescents (POMS-a) and Pittsburgh Sleep Quality Index (PSQI). Dependent t-tests were used to assess the effects of the intervention on hydration, mood, and sleep quality. Uosmo was greater and Ucol was darker in the control group (mean ± SD) [Uosmo: INT = 828 ± 177 mOsm·kg−1, CON = 879 ± 184 mOsm·kg−1, (p = 0.037], [Ucol:INT = 5 ± 1, CON = 5 ± 1, p = 0.024]. USG, POMS-a, and PSQI were not significant between the groups. At-home daily afternoon Ucol was darker in the control group [INT = 3 ± 1, CON = 3 ± 1, p = 0.022]. Access to Creative Roots® provides a small, potentially meaningful hydration benefit in children. However, children still demonstrated consistent mild dehydration based on Uosmo, despite consuming the beverage.
