Shift workers are more likely to have diets that promote chronic inflammation, according to a study by researchers at the University of South Carolina Arnold School of Public Health. Researchers used data from the National Health and Nutrition Examination Survey (2005 to 2010) to create a dietary inflammatory index (DII) in relation to shift work. Categories included day workers, evening/night shift workers, or rotating shift workers. Among all shift workers – and specifically rotating shift workers – higher (ie, more pro-inflammatory) mean DII scores were observed compared with day workers. Women tended to express strong evening/night shift effects. The results are published in this month's issue of the Journal of Occupational and Environmental Medicine.
