Opis:
Objectives The aim of the study was to assess the nutritional status and diet of midwives working on a shift schedule in public hospitals in Wrocław, Poland, and to analyze the variation in their diet according to their working hours (day shift, night shift) and on a non-working day. Material and Methods In the group of 50 midwives, employed in 4 public hospitals in Wrocław weight and body composition, waist and hip circumference, waist-hip-ratio and BMI were assessed. The nutritional habits and quality of the study participants’ diets were assessed by 3-days food dietary recall, including 1 day shift day, 1 night shift day, and 1 non-working day. Results More than half of the subjects were assessed as having excess body weight (BMI ≥25 kg/m2). Thirty percent of participants had BMI ≥25–<30 kg/m2 and 24% BMI ≥30 kg/m2, 70% had a body fat percentage >30%. Fifty-six percent of the diets had an energy value <90% of the subject’s total daily energy expenditure. Significantly higher energy value of diets on the night shift day compared to the morning shift day (1959.05±596.09 kcal vs. 1715.36±654.55 kcal, p = 0.01) were observed. The same relationship applied to cholesterol content (349.50±155.33 mg vs. 261.39±190.59 mg, p = 0.002). A high intake of phosphorus and sodium, exceeding the recommended dietary intake, was noticed. Conclusions The occurrence of a night shift in the shift work schedule is an element of that model that may have a significant impact on the nutritional and health value of shift workers’ diets. Therefore, it seems reasonable to implement nutritional education programs promoting healthy eating choices and habits during night work.

Opis:
ObjectivesEpidemiological observations indicate that female flight attendants are exposed to some reproductive and endocrine system disturbances. The aim of the study was to determine the incidence of hyperprolactinemia among female flight attendants, and to identify factors affecting the secretion of prolactin in female flight attendants working within 1 time zone as well as on long-distance flights.Material and MethodsThe cross-sectional study covered 103 women aged 23–46 years. The study group (I) was divided into 2 subgroups: subgroup Ia comprising female flight attendants flying within 1 flight zone, and subgroup Ib composed of female flight attendants working on long-distance flights. The control group (II) included women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, the body mass index, menstrual cycle regularity, the length of service, the frequency of flying, the prolactin, estradiol and progesterone concentrations, and the result of endometrial biopsy. Descriptive and inferential statistics methods were used to compile the data.ResultsThe incidence of hyperprolactinemia in the female flight attendants (46%) was significantly higher than in the control group (9%), p < 0.001. Differences between subgroups Ia and Ib regarding individual concentrations were not statistically significant (p = 0.425). Hyperprolactinemia among the female flight attendants working ≥15 years is present slightly more often than in those working <15 years: 46% vs. 45% (p > 0.05). No significant difference was revealed in the secretion of prolactin between the study participants spending <60 h/month flying and those spending ≥60 h/month flying (p > 0.05).ConclusionsHyperprolactinemia is more common in female flight attendants than in the general population. High values of prolactin concentration in flight attendants are rarely manifested in clinical symptoms. The frequency of flying and the length of service do not affect the development of hyperprolactinemia or the mean prolactin concentration.

Opis:
The examination of Air Traffic Controllers (ATCs) from the Warsaw Airport (Poland) included 24-hr ECG monitoring. The participants were 10 civil ATCs, 9 males and 1 woman. The study was carried out on a group of 19 ATCs during their duty periods, 14 of them working 12-hr shifts and 5 performing 24-hr duties. The participants collected urine every 4 hrs, and cortisol concentration was determined. Further, the survey included the quality and duration of sleep, and subjective fatigue in the 62 participants. In ATCs, shift work modifies natural rhythms of the circulatory system and decreases the ability for intensified mental work at night. In consequence ATCs experience frequent sleep disorders.

Opis:
Liczne doniesienia naukowe wskazują na negatywny wpływ pracy w niestandardowych (zwłaszcza nocnych) godzinach na ogólne funkcjonowanie i zdrowie człowieka. Prezentowany artykuł stanowi próbę podsumowania dotychczasowej wiedzy, dotyczącej wpływu pracy na funkcjonowanie poznawcze pracowników, a uzyskanej na podstawie badań z zastosowaniem obiektywnych metod diagnostycznych. Poruszona została także problematyka różnic indywidualnych w tolerancji na tę formę aktywności, czynników chroniących przed skutkami pracy zmianowej oraz profilaktyki zaburzeń poznawczych
Various sources point out that shift work (especially night shifts) has a negative influence on peoples' health and their everyday functioning. This article strives to start a discussion about the current state of knowledge on the impact of shift work on workers' cognitive functioning, on the basis of studies, which used objective diagnostic methods. It also covers individual differences in tolerance to shift work and prevention of cognitive impairments due to shift work.
