Introduction: metabolic syndrome (MS) is a clustering of risk factors known to promote cardiovascular disease and diabetes. Environmental factors, such as unhealthy diet, play a major role in the development of this condition. In this study, we evaluated the prevalence of MS and its association with food intake quality among Chilean adults. Methods: we analyzed data of 2 561 adults (. 18 years-old) included in the last National Health Survey (NHS 2009-2010) who had appropriate information to diagnose MS based on ATP III-NCEP guidelines. Consumption frequency of fish, whole grains, dairy, fruits and vegetables was also analyzed and associated with MS prevalence. Using a healthy diet score (HDS), we described the overall diet quality and further correlated it with MS prevalence. Results: we found that lower whole grain intake was associated with greater MS prevalence (OR = 1.78; 95% CI: 1.088-2.919; p = 0.022). HDS showed better diet quality among women and in subjects with increasing age and higher educational level. A HDS < 3 points was associated with an increased risk of MS (OR HDS < 3 / HDS ≥3 = 3.69; 95% CI 1.884-7.225, p < 0.001). Conclusion: Chilean adult population exhibits a high prevalence of MS linked to a poor diet quality.
