Analysis of Selected Body Composition Parameters and Ergonomic Safety among Professionally Active Nurses in Poland: A Preliminary Prospective Monocentric and Observational Study.

Nurses consist of an occupational group that is particularly exposed to harmful work-related factors such as prolonged working hours, severe stress, fatigue, and excessive strain on the musculoskeletal system. According to nurses, the limitation of the application of ergonomic principles of work may contribute to the occurrence of numerous dangerous behaviors, improper eating habits, or deficiency of systematic physical activity. The most common consequences are nutritional disorders and musculoskeletal system dysfunctions. This prospective observational study was aimed at evaluating selected parameters of the body composition of professionally active nurses and at determining work-related risks during nursing activities. The study group consisted of 37 active nurses (38.38 ± 11.33 years). The research tool was a device for bioelectrical impedance analysis (BIA). A questionnaire designed by the authors was also implemented, which covered ergonomic principles, musculoskeletal injuries, and nutritional habits. In the present study, it was shown that all average values of the tested nurses' body composition parameters were within the normal range. The majority of respondents (97.3%) reached a high level of body water. A statistically significant correlation was found between the knowledge of the workplace ergonomic principles and body mass index. In conclusion, musculoskeletal pain and lack of implementation of ergonomic behaviors are a significant problem among nurses, which may be the cause of overweight or obesity in this occupational group.
