Objectives: Research investigating the association between reproductive health and diet has predominantly focused on the antenatal and prenatal periods, as well as childbirth in women, and semen quality in men. There is a limited amount of research addressing female fertility assessed as ovarian reserve in relation to diet. The main aim of this study was to evaluate the association between dietary patterns and the parameters of ovarian reserve, such as antral follicle count (AFC), anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol (E2) - predictors of reproductive health in women of childbearing age.

Material and methods: Women aged 24-39 years (N = 511) were enrolled from fertility clinic in central Poland. The count of antral follicles was determined using ultrasonography (USG), FSH and E2 levels were measured using a chemilumi- nescence method and for determination of AMH level, an enzyme-linked immunosorbent assay method was employed. Diet was assessed according to food frequency questionnaire and dietary patterns were identified by factor analysis. Women were classified into 3 groups according to scores of each dietary pattern: Western, mixed, prudent.

Results: Higher adherence to the prudent dietary pattern in obese women was associated with significantly higher AFC (p = 0.03) and AMH (p = 0.05) as compared to participants with the Western dietary pattern. The results were adjusted for age, BMI, smoking and duration of fertility. Increased consumption of mixed dietary pattern was not statistically significant associated with any of examined ovarian reserve parameters.

Conclusions: The prudent dietary pattern is positively associated with ovarian reserve in a cohort of women seeking fertility care. Continued research in this area will provide nutritional guidance for clinicians and their patients and provide novel insight on potential modifiable lifestyle factors which can be associated with ovarian reserve.

Objectives: The COVID-19 pandemic has led to significant changes in daily life, including changes in physical activity levels. This study aims to examine the impact of the pandemic on sport participation and walking among Polish adults.

Material and methods: The data was collected using the National Test for Poles' Health, a large-scale online survey. The survey was conducted before and 1 year after the pandemic onset in Poland (March 2020 and March 2021), with >300 000 participants in each year.

Results: The results revealed that the percentage of respondents engaging in at least 2 h/week of sport increased by 2.3% (from 24.6% to 26.9%) (p < 0.0001) and percentage of respondents not engaging in any sport decreased by 2.5% (from 48.0% to 45.5%) (p < 0.0001). These trends were observed across different age, sex, dwelling-place, education level, and employment groups. Percentage of respondents declaring they spend >2 h/day on walking also increased, from 5.6% to 6.6% (p < 0.0001). Furthermore, a positive association was found between sport participation and walking time (p < 0.0001).

Conclusions: The findings suggest a slight improvement in physical activity levels among Polish adults during the pandemic, which may be attributed to factors such as increased time available due to remote work and the prioritization of health during the crisis. Further research is needed to explore the long-term consequences of the pandemic on physical activity and public health. Int J Occup Med Environ Health. 2024;37(4):468-81.

Objectives: The study aimed to assess the mental health and well-being of Lithuanian healthcare workers by gathering demographic information, identifying common stressors affecting the work environment, evaluating mental health, and exploring directions for psychosocial care. Additionally, the research explored the prevalence of considering a career change among respondents.

Material and methods: The study included 1618 responders who completed an online survey in December 2021 - January 2022. Participants included in this study: physicians, nurses, residents and other healthcare workers. It evaluated their demographics, most common stressors affecting their work environment and mental health on the Depression, Anxiety and Stress Scale - 21 (DASS-21) scale. Lastly, all responders asked if they had considered changing their occupation to a non-medical job. Univariate analysis was performed using χ2 and Student's t test, and binary logistic regression evaluated career change predictors.

Results: Career change was considered by 1081 (66.8%) responders. The main career change predictors were poor working conditions (OR 1.91, p < 0.001), direct contact with patients (OR 1.84, p < 0.001), lack of career perspectives (OR 1.95, p < 0.001), mobbing (OR 1.67, p = 0.001) and exhaustion (OR 1.51, p = 0.005). After evaluating DASS-21 scores, it was found that 23% of respondents had severe and extremely severe depression symptoms, 27.4% severe and extremely severe anxiety, and 21.4% had severe and extremely severe stress levels.

Conclusions: Lithuanian healthcare workers are in high distress and have poor mental health. They are in need psychosocial assistance to avoid burnout and staff loss. Int J Occup Med Environ Health. 2024;37(3):287-99.

Objectives: This study aims to define and assess communal and agentic workplace climates (AWC), 2 pivotal dimensions perceived by employees within organizational contexts. Communal workplace climate highlights employees' well-being, while AWC emphasizes productivity-related aspects.

Material and methods: To enhance comprehension, the Communal and Agentic Workplace Climate Scale (CAWCS) was created and validated through a series of studies. The research involved 4008 employees from diverse positions and organizations across Poland. Initially, a pool of 20 items was designed to reflect these dimensions, with exploratory factor analysis identifying a robust set of 12 items.

Results: Confirmatory factor analysis substantiated the 2-factor structure of CAWCS. Reliability analyses indicated good internal consistency, supported by correlation analyses linking scale scores with diverse attitudinal and behavioral constructs.

Conclusions: This validation confirms the validity of CAWCS and highlights the significant associations between employees' perceptions of these dimensions and their workplace experiences and behaviors. Int J Occup Med Environ Health. 2024;37(3):311-25.

Objectives: To find possible relationship between asthma exacerbation and metabolomic profile of airways, assessed by non-invasive method - free volatile organic compounds (VOCs) in exhaled air in children.

Material and methods: The study included 80 children aged 4-18 years with asthma: 42 children with a min. 3 asthma exacerbations in the past 12 months, and 38 children without a history of exacerbations in the past year. During the study visit, each patient was examined, medical history (including information regarding atopy and eosinophil blood count) was taken, spirometry and fractional exhaled nitric oxide (FeNO) were tested, an exhaled air sample was taken to test for the presence of VOCs, and the patient also completed standardized form - Asthma Control Questionnaire. Volatile organic compounds were measured by combined gas chromatography coupled to mass spectrometry.

Results: The obtained results of VOCs were correlated with the history of the disease. The 2 gas profiles were defined and they formed 2 clinically distinct clusters (p = 0.085). Cluster 2 was characterized for children with a higher number of bronchial asthma exacerbations and worse lung function parameters (predicted percentage forced expiratory volume in 1 s [FEV₁] [p = 0.023], FEV₁/ forced vital capacity ratio [FVC] [p = 0.0219]). The results were independent of the age, sex, BMI, atopy (house dust mite allergy) and eosinophil blood count.

Conclusions: The study findings suggest that a relative group of gases may be a useful predictor of having asthma exacerbations in children. Additionally, a single FeNO value was unlikely to be clinically useful in predicting asthma exacerbations in children. The VOCs profile reflecting the metabolism of the airway epithelium and local microbiota was associated with the course of asthma, which strongly justifies further prospective validation studies.

Objectives: The aim of this work is to initiate or revive a scientific discussion on the impact of professional life on the parameters of human lifespan.

Material and methods: Presented analysis is based on 8578 Polish elite or well-known person who died in 2001-2021.

Results: The results of the conducted analysis indicate that in the case of men the highest values of the median age at death were characteristic of freelancers (median [Me] ± quartile deviation [QD] 85.5±8.5 years), followed by scientists and academic teachers of the biological and medical specialty (Me±QD 84.0±7.5 years) and officers of power structures (Me±QD 83.5±8.5 years). Subsequently, the highest value of the median age at death was recorded for social activists (Me±QD 83.0±9.5 years), clergy (Me±QD 82.0±7.5 years) and scientists and academic teachers of specialties other than biological and medical (Me±QD 82.0±8.0 years). Significantly, at the very end of this list are athletes (Me±QD 77.0±9.0 years). Nevertheless, the results of the analysis confirm that professional athletes are characterized by higher median age at death compared to the general population. Analysis made only within athletes group demonstrated that the parameters of lifespan of athletes of endurance disciplines (Me±QD 78.0±8.0 years) are the most favorable compared to athletes of other disciplines, in particular in compare to team sports athletes (Me±QD 75.0±10.0 years) or combat sports athletes (Me±QD 75.0±7.1 years).

Conclusions: What is new and innovative in this paper is comparing the lifespan characteristics of athletes in comparison to widely represented group of other professions with higher socio-economic status. Unexpectedly, the lifespan of athletes occurred to be lower than for fast all other analyzed occupational groups, except mainly of entertainment musicians. Finally, the results presented in this paper emphasize the need to analyze the lifespan characteristics of athletes in a broader scope than only in relation to the general population.

Green jobs are to be understood as those jobs directly associated with specific sustainability issues and activities related to the efficiency, quality and innovation of goods and services offered, from an eco-sustainability perspective. The objective of the research was to fill knowledge gaps of new and emerging environmental and occupational risks related to sustainable activities and to understand the impact these might have on workers' psychological and physical well-being. A selection of several scientific articles and a critical analysis of the selected articles was carried out from the perspective of defining the concept of "emerging occupational risks in green jobs," using different keywords in the title or abstract as search criteria. Emerging occupational risks, most prevalent in the green sector are those determined by the rapid introduction of new technologies, new materials, new processes and work organizations. In order to be able to improve prevention and protection at work, it is necessary to act on a more careful and adequate risk assessment, the definition of new professional figures expert in green issues, the expansion of research and development of scientific knowledge, and the improvement of ergonomic aspects.

This article aims to present the overview of the situation during the coronavirus disease 2019 (COVID-19) pandemic about issues concerning the prevalence of mental disorders such as depression, anxiety, rate of suicide attempts, and long COVID (LC) infections in the general population during COVID-19 pandemic. Analysis of the literature (in English, Polish and Spanish language) on topics related to COVID-19, mental disorders (suicide attempts, depression, anxiety) and LC infection published during the 4 years (2020-2023) was done using Pubmed and PubMed Central search engine. Keywords such as "COVID-19," "mental disorders," "long COVID infection," "depression," "anxiety," "suicide attempts" were used during the search. The conduct of this review/comment followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol, which corresponds to a checklist of 27 items designed to facilitate the development and reporting of a robust protocol for systematic reviews or meta-analyses. Overall 35 studies were selected and analyzed in the review on topics: including among others LC (14 studies), suicide attempts (7 studies), mental disorders (depression, anxiety) (14 studies). The main issues raised in the articles were: higher risk of LC symptoms in women, fatigue and brain fog listed as frequently encountered patient's complaints together with anxiety, depression, loneliness, especially in younger age groups and in women. Issues regarding LC, mental disorders and suicide attempts requires further research as the results vary in different countries. Int J Occup Med Environ Health. 2024;37(3):360-80.

Objectives: During computed tomography (CT), a large amount of ionizing radiation is emitted to ensure high quality of the obtained radiological image. This study measured the dose distribution around the CT scanner and the exposure of people staying near the CT scanner during the examination.

Material and methods: The measurements used an anthropomorphic phantom to assess human exposure to ionizing radiation. The probability of inducing leukemia and other cancers as a result of absorbing doses recorded around the CT device was also calculated.

Results: The highest exposure to scattered radiation in the proximity of the CT scanner is recorded at the gantry of the tomograph, i.e., 55.7 μGy, and the lowest, below lower detection limit of 6 μGy at the end of the diagnostic table. The whole-body detector placed on the anthropomorphic phantom located at the diagnostic table right next to the CT gantry recorded 59.5 μSv and at the end of the table 1.5 μSv. The average doses to the lenses in these locations were: 32.1 μSv and 2.9 μSv, respectively.

Conclusions: The probability of induction of leukemia or other types of cancer is low, but the need for people to stay in the examination room during a CT examination should be limited to the necessary minimum. Int J Occup Med Environ Health. 2024;37(3):326-34.

Objectives: Music educators are subjected to many physical and psychological stresses encountered in the workplace. These stresses could be counteracted by certain work-related behavior and experience patterns as personal resources to reduce the negative consequences of stress. The aim of the study was to determine the existing work-related behavioral and experiential patterns and the characteristics of the Work-Related Behavior and Experience Patterns (Arbeitsbezogenes Verhaltens- und Erlebensmuster - AVEM) questionnaire dimensions in the professional group of music educators according to age group.

Material and methods: A total of 205 music educators (66.3% female) from various music schools in Germany participated in the online survey. The subjects were divided into 3 age groups (AG): AG I: ≤35 years, AG II: 36-45 years, AG III: ≥46 years. In addition to sociodemographic and occupational data, the standardized AVEM questionnaire was used according to Schaarschmidt and Fischer. The age and occupation-related data were evaluated in a correlation analysis with the expression of AVEM dimensions.

Results: A total of 71.4% of the music educators were ≥46 years old group. Another 12.8% belonged to AG II, and 15.8% belonged to AG III. The sex distribution in the 3 age groups was comparable (p = 0.261). The expression of all AVEM dimensions was within the reference range. The most pronounced dimension, with a stanine value of M±SD 5.2±2.15, was the willingness to spend. There was also no significant difference in the assignment to the 4 patterns in the 3 age groups (p = 0.669). Age showed a negative correlation with the experience of social support (ρ = -0.354).

Conclusions: The age-independent and high intervention-requiring expressions of the AVEM risk patterns A and B led to the recommendation of workplace prevention and health promotion measures. Therefore, it seems reasonable to promote appropriate stress management measures and resilience during studies. Int J Occup Med Environ Health. 2024;37(2):176-93.
