**6. Ergonomic factors**

The more the harmonization is ensured between employer and work environment, the better the safety and efficiency can be provided to employees [31]. In case there is an inconsistency between the physical capacity of the laborer and the physical requirements, occupational dis‐ eases may occur [32]. Particularly, nurses are in the third row after heavy industry workers and the heavy vehicle drivers who can experience the musculoskeletal system problems [8, 33]. According to the study performed in Turkey in which the prevalence of low back pain in the last 12 months and related factors were examined, it has been shown that the prevalence of low back pain in the last 12 months was at a high level that affects the working life (73.3%) [34]. In another study, we have indicated that the frequency of the low back pain in the past 1 year was 58.3% in nurses and health officers and 33.0% in the sick nurses [35].
