BUSTOS, Patricia et al. Association of C reactive protein levels with metabolic syndrome in adults: a population-based study. Rev. méd. Chile [online]. 2016, vol.144, n.10, pp.1239-1246. ISSN 0034-9887.

Background: Metabolic syndrome is highly prevalent among adults in Chile and represents a health risk. Aim: To determine the relationship between metabolic syndrome (MetS) and its components, with C reactive protein levels (CRP) as an inflammation marker. Material and Methods: The population studied consisted of 736 individuals born in a hospital from Valparaíso Region, aged between 32-38 years at the time of the study. MetS was identified according to the Adult Treatment Panel (ATP) III guidelines and inflammation was measured using ultra-sensitive CRP. This parameter was classified as normal for values from 0 to 3 mg/L, high for values from 3.01 to 10 mg/L and very high for values > 10 mg/L. Results: Median CRP was in the normal range (1.9 mg/L, interquartile range 0.7-5.2) and was higher among women than men (2.2 and 1.4 mg/L respectively, p < 0.01). Twenty seven percent of participants had MetS. One-fourth had high blood glucose values, one-third had high triglyceride levels and 28% had blood pressure values over those established as normal in MetS. Elevated waist circumference (WC) and low HDL cholesterol were found among almost 50% of participants. A relationship between MetS and high CRP was only found among men with an Odds ratio (OR) of 2.04 (95% confidence intervals (CI): 1.11-3.73). The same association was observed for high triglyceride levels with an OR of 2.02 (CI: 1.17-3.49) and high WC with an OR of 3.89 (CI: 2.06-7.36). Among women, the only relationship observed was between abdominal obesity and very high CRP with an OR of 2. 65 (CI: 1.20-5.84). Conclusions: Metabolic syndrome, high triglyceride levels, and abdominal obesity were associated with inflammation only in men.
