MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Approximately 20% of the overall workforce is involving in a shift work schedule, which is equivalent to nearly 0.7 billion workers. It has been several studies and systematic reviews reported that shift work could contribute a risk to abdominal obesity, that was identified to be associated with increased mortality. However, the previous related studies derived from different industries and companies that held with various occupational settings of night shift work, and the results have been inconsistent or lack of statistical power. We believed that a better understanding of the knowledge gaps on the associations between specific obesity types and different shift work settings has important implications for occupational health practice. Our meta-analysis provided a clearer picture for the association between night shift work and overweight/ obesity with a potential gradient association, especially for the abdominal obesity.
