Introduction The assessment of energy expenditure (EE) at workplaces maintains a central topic in occupational health due to increasing work-related issues. Today 80% of employees in the healthcare system are women. Limited research concerning their physical activity at work is available. The purpose of the study was the investigation of body composition, maximum physical capacity and quantification of physical work activity for female healthcare workers under real-time conditions. Methods Occupational physical activity (PA) of 33 female healthcare workers in a university hospital was quantified. Health associate professionals (HAP), health professionals (HP), and females working from cleaners and helpers (CH) department participated. All underwent cardio pulmonary exercise test. For every working task VO2, VCO2 and RER were measured and EE was calculated individually for each task. Results Forty-two different working tasks were identified and grouped in seven categories to compare physical activity (PA): 'office and laboratory work', 'bedside patient care', 'instrument reprocessing, packing boxes', 'walking with patient, or alone', 'pushing carts or wheelchairs', 'strenuous cleaning in bent posture' and 'lifting heavy boxes, weights or items'. By comparing groups of healthcare workers, CH and HAP spent significant (p < 0.01) more EE (in kcal/min) 3.9 resp. 3.2 than HP 2.5. Light PA e.g. office and laboratory work (2.7 ± 0.6) and bedside patient care (2.9 ± 0.7) were accomplished by HP and HAP while HAP and CH performed moderate PA such as 'packing boxes' (3.6 ± 0.8), 'pushing carts' and 'strenuous cleaning' (4.7 ± 0.9). Work performed by CH and HAP, i.e. 'strenuous cleaning' and 'lifting heavy items' showed highest kcal per kg Fat Free Mass (FFM) per hour with 5.80 [4.05–7.81] and 6.94 [5.18–9.03] kcal/kgFFM/h. Conclusion Our findings lend preliminary support to the hypothesis that the majority of activities in female healthcare workers were of low and moderate PA and can be accomplished by middle aged and even older female workers. CH performed tasks with heavy physical activities (PA) like cleaning and lifting heavy weights. HAP performed light/moderate PA below their maximum physical capacity. [ABSTRACT FROM AUTHOR]

Physical effort of workload of female employees in the healthcare system is perceived to rise. Research focused mainly on physical activity levels of registered nurses (RN). Therefore, we investigated physical strain during daily routine of other hospital workers next to RN. O2uptake, heart rate, breathing frequency and ventilation were measured in 33 female medical (associate) professionals (MAP) and Cleaners&Helpers (Cl&H) using Oxycon Mobile. Physical work load was compared to standardized CPET. Wilcoxon-test and ANOVA were calculated using SPSS 20.0. Cl&H performed heavy-lifting and had the lowest power during CPET. The O2-uptake for heavy-lifting as strong effort, differed significantly from office work (p<0.001) and bedside-patient-care (p=0.001). Compared with metabolic equivalent (MET) cleaning, heavy-lifting, and office work are underestimated. Bedside-patient-care, walking, pushing performed by MAP are overestimated. While Cl&H had the lowest maximal power in CPET, their work required the highest O2-uptake. The tasks are underestimated in the MET-tables. [ABSTRACT FROM AUTHOR]

Abstract Background Environmental Tobacco Smoke (ETS) was classified as human carcinogen (K1) by the German Research Council in 1998. According to epidemiological studies, the relative risk especially for lung cancer might be twice as high in persons who have never smoked but who are in the highest exposure category, for example hospitality workers. In order to implement these results in the German regulations on occupational illnesses, a valid method is needed to retrospectively assess the cumulative ETS exposure in the hospitality environment. Methods A literature-based review was carried out to locate a method that can be used for the German hospitality sector. Studies assessing ETS exposure using biological markers (for example urinary cotinine, DNA adducts) or questionnaires were excluded. Biological markers are not considered relevant as they assess exposure only over the last hours, weeks or months. Self-reported exposure based on questionnaires also does not seem adequate for medico-legal purposes. Therefore, retrospective exposure assessment should be based on mathematical models to approximate past exposure. Results For this purpose a validated model developed by Repace and Lowrey was considered appropriate. It offers the possibility of retrospectively assessing exposure with existing parameters (such as environmental dimensions, average number of smokers, ventilation characteristics and duration of exposure). The relative risk of lung cancer can then be estimated based on the individual cumulative exposure of the worker. Conclusion In conclusion, having adapted it to the German hospitality sector, an existing mathematical model appears to be capable of approximating the cumulative exposure. However, the level of uncertainty of these approximations has to be taken into account, especially for diseases with a long latency period such as lung cancer.

Background: Prevalence of chronic obstructive pulmonary disease (COPD) is increasing in Germany. This study examined the work performance of healthy women compared to those with mild COPD., Patients and Methods: Nineteen women suffering from COPD Global Initiative for Chronic Obstructive Lung Diseases stage I and 41 healthy women underwent standardised cardiopulmonary exercise test (CPET) in comparison to 5 typical work-related tasks. Oxygen uptake, carbon dioxide output, ventilation volume, breathing frequency, heart rate and respiratory exchange ratio (RER) were measured. The activities were quantified. Wilcoxon test and ANOVA were calculated using the SPSS software., Results: Patients with COPD had a lower exercise capacity compared to healthy women and also showed lower performance during work-related activities. Patients with COPD had a lower oxygen uptake (p<0.001), a higher breathing frequency was accompanied by a higher Borg scale. The heart rate and the ventilation volume as a percentage of maximum CPET were significantly higher in patients with COPD. Women suffering from progressive symptoms had lower oxygen uptakes and RER, whilst breathing frequency and Borg scale were elevated., Conclusion: Even at an early stage of the disease, patients with COPD exhibited limitations in work-related tasks., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J.
