[Determinants of the locomotor system load and their health effects among midwives].

Background: This paper presents an analysis of current knowledge of ergonomic weight lifting, work conditions and their health effects on the locomotor system in the selected group of midwives employed in hospitals.

Material And Methods: The analysis was carried out in a population of 107 midwives, aged 25-57 years. The 36-45 age group was most representative (57%). In the study, a questionnaire was used to solicit information on work conditions, knowledge, and locomotor system complaints.

Results And Conclusions: Knowledge of ergonomic work with patients is very limited among midwives. The ergonomic equipment in departments and rooms, where the analyzed population worked was inadequate. For 85% of midwives the average weight of patients during lifting/carrying exceeded Polish norms (20 kg). Statistically, complaints concerning the L-S backbone were reported most frequently. The authors found a statistically significant relationship between musculoskeletal complaints (L-S back bone in particular) and work in the forced position. In 25 (44%) midwives who assisted in deliveries in vertical position or in water, significant musculoskeletal complaints during or after a large number of deliveries were noted. Over half (64%) of the study group reported musculoskeletal complaints at least once a month and for 38% of midwives back pain is a constant problem (pains at least once a week). Everyday complaints are noted in 5%; 3-5 times per week in 14%, and 1-2 time per week in 19% of midwives. In view of the above data, an analysis of ergonomic conditions of midwives' employment and their improvement is warranted.
