Osteoarthritis and its management - Epidemiology, nutritional aspects and environmental factors.

Osteoarthritis (OA) is the most prevalent chronic rheumatic diseases worldwide, with a strong impact on individual and population health. OA is a clinically heterogeneous disease presenting with different clinical phenotypes recognising systemic and local risk factors. The pathogenesis is multifactorial including constitutive features of the joint, non-modifiable and modifiable risk factors. Epidemiological studies highlight the link between metabolic syndrome and OA and the effect of interplay between immunological and metabolic processes is getting increasing emphasis because of to the discovery that metabolic syndrome is implicated in OA pathogenesis and progression. In addition, recent findings suggest a potential role of dietary factors in susceptibility and progression of OA. In this review, we summarise the most robust evidence on epidemiology and classical risk factors OA, also exploring the most recent evidence on metabolic changes and Mediterranean diet for OA as a possible target to impact on the natural history of the disease.
