Abstract
BACKGROUND: Bottling tasks postures may increase risk for developing work related musculoskeletal discomforts (WRMDs). Postural evaluation with epidemiological investigation for possible association may be appropriate for planning ergonomic programs. OBJECTIVE: To evaluate working postures and investigate associations between postural risks and prevalence of WRMDs among beverage bottling workers. METHOD: 301 beverage bottling company workers (8 work-stations) participated in this survey. They were required to complete a modified standard Nordic questionnaire, and their working postures examined utilizing Rapid Entire Body Assessment (REBA). RESULTS: Postural risks ratings were high (8- 10) to very high (11- 15). Shoulder was the most commonly reported body part with WRMDs except at the carbonating workstations where Neck, Upper and Lower back discomforts were the most common (60.0%). The compounding workstations recorded the highest prevalence of WRMDs in all body regions except shoulder and wrist. There was a significant association between working posture and occurrence of WRMDs in at least one body part. Similarly, working posture was significantly associated with WRMDs at Neck, Upper back and Wrist. CONCLUSIONS: Working postures may be exposing beverage bottling workers to significant risk of developing WRMDs in at least one body part, more specifically, Shoulder, Neck, Upper back and Wrist. Intervention aimed at reducing postural risks is necessary.
