[UNHEALTHY FOOD INTAKE IS LINKED TO HIGHER PREVALENCE OF METABOLIC SYNDROME IN CHILEAN ADULT POPULATION: CROSS SECTIONAL STUDY IN 2009-2010 NATIONAL HEALTH SURVEY]

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.

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.

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).

Chilean adult population exhibits a high prevalence of MS linked to a poor diet quality.
