Description:Objective
Shiftworkers are affected by diet- and inflammation-related diseases including cardiovascular disease, diabetes, and cancer. We examined a dietary inflammatory index (DII) in relation to shiftwork from National Health and Nutrition Examination Survey data (2005–2010).
Methods
The DII was calculated using data from a 24-hour dietary recall. Shiftwork categories included day workers, evening/night shiftworkers, or rotating shiftworkers. General linear models were fit to examine the relationship between shiftwork and adjusted mean DII values.
Results
Among all shiftworkers and specifically rotating shiftworkers, higher (i.e., more pro-inflammatory) mean DII scores compared to day workers (1.01 and 1.07 vs. 0.86, both p≤0.01) were observed. Women tended to express strong evening/night shift effects.
Conclusions
More pro-inflammatory diets observed among shiftworkers may partially explain increased inflammation-related chronic disease risk observed in other studies among shiftworkers compared to their day-working counterparts.
