Objectives Only a few studies have been undertaken to analyze the dietary habits of people with cardiovascular diseases. The aim of this study was to evaluate the dietary behaviors of working people who were hospitalized due to experiencing the first acute cardiovascular incident. Material and Methods In the study, the Functional Activity Questionnaire was used. The study was conducted in 2 groups. The first group included all the men hospitalized during 1 year (January–December 2009) in 2 clinics of cardiology, who were professionally active until the first myocardial infarction (MI). It comprised 243 men aged 26–70 years. The reference group consisted of 403 men, blue- and white-collar workers, aged 35–65 years. Results The body mass index of the MI patients was significantly higher (p = 0.006). The frequency of consumption of particular products in the MI group and in the reference group differed significantly for 11 of 21 products. The MI patients significantly less frequently reported the daily consumption of fruit, raw vegetables, cheese, vegetable oils and fish. In this group, the consumption of salty (p = 0.0226) or fatty (p < 0.0001) foods was significantly higher. It was shown that, after adjusting for age, education and the type of work, the daily consumption of fish, salads and cooked vegetables, as well as fruit and vegetable oils, significantly reduced the risk of myocardial infarction. An increased MI risk was, in turn, associated with obesity and preference for fatty foods. Conclusions The authors found that diet significantly modified the MI risk in the examined workers. This indicates that an important aspect of prevention activities among working people should involve education about proper dietary habits. Int J Occup Med Environ Health. 2019;32(6):853–63

The article presents the problem of civilization diseases among female white collar workers. The aim was to prove the relationship between the applied diet and practiced physical activity, and civilization diseases. The research conducted for the needs of the article was to illustrate trends in female white collar workers’ behaviours in terms of the prevention of civilization diseases. The paper demonstrates several important issues regarding respondents’ work and spending their leisure time actively. They also provided the information about the diet they applied and its impact on the prevention of ill-health. The research indicated the relations mainly between a physical activity and well-being of respondents. Analysing everyday eating habits of the respondents it was shown that they do not influence the general causes of development of civilization diseases.

Due to the controversy related to the necessity to wear protective masks and the negative perceptions of users, an attempt was made to analyze the available scientific research on the physiological consequences of wearing various types of masks. The literature review includes publications available in the PubMed bibliographic database, describing symptoms and complaints of mask users (e.g., the feeling of discomfort, fatigue, headaches), different physiological reactions depending on the type of mask (surgical masks, masks with an exhalation valve, with air flow, etc.) as well as the influence of air composition, temperature and humidity in the space under the mask. The impact of using the mask on the ability to exercise (maximal effort, moderate effort) and mental work was outlined. The consequences of wearing masks by people in a different physiological state (pregnancy) were discussed. Proposals for the organization of work were also presented in order to minimize the negative consequences for people wearing masks. The analysis of the presented studies shows that, regardless of the type of masks worn, they can intensify the body’s reactions to a varying degree, increasing the physiological cost of work and worsening the ability to make both physical and mental effort. In addition, the mask can contribute, among others, to more frequent headaches, symptoms of fatigue or the subjective feeling of discomfort. However, despite these adverse effects, the use of masks is important to protect people against harmful factors in the work and communal environments, and during the current SARS-CoV-2 pandemic, it has become a necessity. The discomfort of wearing a mask can be reduced by taking appropriate breaks. It should be emphasized that the rhythm of work and breaks in wearing the mask should take into account the individual limitations of the employee. Med Pr. 2021;72(5):569–89

Ze względu na kontrowersje związane z koniecznością noszenia masek ochronnych i negatywne odczucia użytkowników podjęto próbę analizy dostępnych badań naukowych na temat fizjologicznych konsekwencji noszenia różnego rodzaju masek. W przeglądzie literatury uwzględniono publikacje dostępne w bazie bibliograficznej PubMed, opisujące dolegliwości i skargi użytkowników masek (m.in. poczucie dyskomfortu, zmęczenie, bóle głowy), zróżnicowane reakcje fizjologiczne zależne od rodzaju maski (maski chirurgiczne, z wentylem wydechowym, z nawiewem powietrza itp.), a także oddziaływanie składu powietrza, temperatury oraz wilgotności w przestrzeni pod maską. Omówiono wpływ korzystania z maski na zdolność do wysiłku fizycznego (wysiłek maksymalny, umiarkowany) i umysłowego. Przedyskutowano konsekwencje noszenia masek przez osoby w odmiennym stanie fizjologicznym (ciężarne). Wysunięto także propozycje organizacji pracy w celu zminimalizowania negatywnych skutków dla osób noszących maski. Analiza przedstawionych badań wskazuje, że maski – niezależnie od typu – mogą w różnym stopniu nasilać reakcje organizmu, zwiększając koszt fizjologiczny jego funkcjonowania i pogarszając zdolność do wykonywania wysiłku zarówno fizycznego, jak i umysłowego. Ponadto mogą one przyczyniać się m.in. do częstszego występowania bólów głowy, objawów zmęczenia czy subiektywnego poczucia dyskomfortu. Mimo tych niekorzystnych skutków używanie masek jest istotne przy ochronie przed czynnikami szkodliwymi w środowisku pracy i komunalnym, a w okresie panującej obecnie pandemii wirusa SARS-CoV-2 staje się koniecznością. Dyskomfort związany z noszeniem maski można zmniejszyć poprzez stosowanie odpowiednich przerw. Należy podkreślić, że rytm pracy i przerw w noszeniu maski powinien uwzględniać indywidualne ograniczenia pracownika. Med. Pr. 2021;72(5):569–589
