ObjectiveThe aim of this study was to investigate the differences in adherence to the Mediterranean diet, assessed by the alternative Mediterranean Diet (aMED) score, and diet quality, assessed by Healthy Eating Index 2015 to 2020 (HEI-2015), between presence and type of arthritis (rheumatoid arthritis and osteoarthritis). Additionally, the study investigated the association between aMED scores and HEI-2015 scores and the presence of arthritis.MethodsCross-sectional data from four cycles (2007-2014) of the National Health and Nutrition Examination Survey were used and weighted to produce a nationally representative sample. Arthritis information was extracted from the Medical Conditions file and recoded into relevant variables. Food group and nutrient data from the 24-h recall was transformed to provide aMED and HEI-2015 scores.ResultsIndividuals with arthritis had significantly worse adherence to the Mediterranean diet and diet quality. aMED scores were 3.43 ± 0.04 for individuals with arthritis and 3.54 ± 0.03 for individuals without arthritis (P = 0.014). HEI-2015 scores were also lower in individuals with arthritis (51.41 ± 0.37) than in those without (53.50 ± 0.28; P < 0.001). There were no significant differences in aMED or HEI-2015 scores between individuals with rheumatoid arthritis and those with osteoarthritis. There were also no associations between aMED scores or HEI-2015 scores and the presence of arthritis.ConclusionsIndividuals diagnosed with arthritis can take steps to improve their diet quality as a possible route to reduce arthritis symptoms and maintain a healthy body weight. Further research on dietary patterns and their potential to treat and manage arthritis is warranted.Copyright © 2019 Elsevier Inc. All rights reserved.
