"Objective This study aimed to investigate the effectiveness of a prevention program on work ability, health, and sick leave targeted at construction worksites. Methods A total of 15 departments (N=297 workers) from 6 construction companies participated in this cluster randomized controlled trial and were randomly allocated to the intervention (8 departments; N=171 workers) or control (7 departments; N=122 workers) group. The intervention consisted of two individual training sessions with a physical therapist aimed at lowering the physical workload, a rest-break tool to improve the balance between work and recovery, and two empowerment training sessions to increase the worker's influence at the worksite. Data on work ability, physical and mental health status, and musculoskeletal symptoms were collected at baseline, and at 3, 6, and 12 months follow-up. Sick leave data were obtained from the companies. Results Overall, no differences in work ability [? 0.02, 95% confidence interval (95% CI) -0.34–0.37] or physical and mental health status (? -0.04, 95% CI -1.43–1.35, and ? 0.80 95% CI -0.51–2.11, respectively) were found between the intervention and control group. The intervention showed an overall decline in musculoskeletal symptoms (ranging from OR 0.68, 95% CI 0.34–1.33, to OR 0.86, 95% CI 0.47–1.57) and long-term sick leave (OR 0.44, 95% CI 0.13–1.26) among construction workers. Both reductions were not statistically significant. Conclusion The prevention program seemed to result in a beneficial but not statistically significant decline in the prevalence of musculoskeletal symptoms and long-term sick leave among construction workers, but showed no effects with regard to work ability, physical health, and mental health."

"Workers can accidentally transport chemical hazards from the workplace to the home, known as “take-home exposures.” Recent take-home lead-poisoning cases highlight the need for effective prevention training. A one-hour take-home prevention training was developed in partnership with a nonprofit. The training was administered and evaluated during two training sessions with twenty-one trainees. The training was composed of a lecture and interactive activities. An illustrated poster was used with different prevention actions within a story line to reduce take-home exposures under three categories: facilities with formal health and safety programs, small businesses, and outdoor work. The effectiveness and acceptability of the training was measured by a survey and pre- and post-training exams. The second training exam responses showed a 14 percent (84 percent to 98 percent) increase in take-home prevention knowledge. Community-based prevention training could reduce the burden of chemical exposures on vulnerable workers and their families."
