Description of Studies: Each of the three participants in the workshop has designed an epidemiological study that prospectively follows workers wearing and not wearing belts for occurrences of back pain and injuries. The studies differ in size and in the type of industry and average workload; however, all are prospective cohort studies in design. The three studies use different approaches to randomization. The Montreal study randomized individual workers to wear belts or not, the Amsterdam study randomized groups of 15 or fewer workers to wear belts or not, and the NIOSH study is allocating groups of about 40 workers in newly opened stores to either mandatory or voluntary belt-wearing. The Amsterdam study will utilize a factorial design of four groups that compares the effect of back belts separately and together with lifting instructions. The NIOSH and Montreal studies will utilize a two-group (belt vs no belt) design.
