Dietary inflammatory index,bone health and body composition in a population of young adults: a cross-sectional study

Abstract

Diet quality has been postulated as a relevant factor in disorders like obesity and osteoporosis as it modulates inflammatory biomarkers. The aim of this study was to investigate whether the dietary inflammatory index (DII) is associated with bone health status and body composition parameters in a population of young adults. The study population consisted of 599 young adults (aged 20.41?±?2.72). Linear regression analysis revealed that weight and fat-free mass (FFM) were significantly associated with the DII after adjustments for age, sex and total energy (β?=??0.91, 95% CI ?1.782, ?0.213, p?=?.013 and β?=??0.059, 95% CI ?0.842, ?0.107, p?=?.011, respectively). Our results suggest that the inflammatory potential of diet, measured using the DII, is associated with obesity-related parameters such as FFM and weight, although it may not contribute to osteoporosis in early adulthood.
