Epidemiology of Musculoskeletal Symptoms Among Milkers and Dairy Farm Characteristics in Sweden and Germany.

International studies have shown that musculoskeletal symptoms (MSS) and disorders (MSD) are common among dairy farm milkers. Although dairy production is diverse, it has so far not been possible to explain the high risk by production parameters. Two national studies carried out under similar conditions were the incentive to merge the data and increase the sample size. The Standardized Nordic Questionnaire was used to assess MSS prevalence among 92 Swedish and 116 German male and female milkers. Eighty-four percent and 85% of the Swedish and German milkers reported MSS in at least one body part. Highest prevalence was reported in the lower back, shoulder, and neck. Females showed a significantly higher risk of MSS. Apart from that, small significant influence of MSS was found for other risk factors. These findings indicate that technical and organizational modifications of the work place design in milking parlors are needed.
