Diet, Sleep and Metabolic Syndrome Among a Legal Amazon Population, Brazil

Metabolic syndrome incidence is increasing worldwide then it is important to study the possible risk and protective factors. Our previous study suggested an association between coffee consumption and metabolic syndrome. The aim of this study was to address possible associations between dietary lifestyle factors with metabolic syndrome. In a case-control study we compared 74 metabolic syndrome patients with 176-matched controls attended at a public health central unit. Incident cases diagnosed according to ATP III criteria were matched with control group composed of healthy subjects performing routine examinations. Having lower educational level compared to highest levels tend to increase metabolic syndrome prevalence, which was not statistically significant. Similar pattern was observed for marital status. No difference was found regarding gender and metabolic syndrome odds. Interestingly, daily drinking two to three cups of coffee (OR=0.0646, 95% CI, 0.0139-0.3005, p=0.0005) or until 2 cups of milk were inversely associated with metabolic syndrome odds (OR=0.5368, 95% CI, 0.3139-0.9181, p=0.0231). Sleeping seven to eight hours per night was also associated with decreased odds of metabolic syndrome (OR=0.0789, 95% CI, 0.0396-0.1570, p<0.0001). Eating at least two portions of chocolate was also associated with decreased risk of metabolic syndrome (OR=0.3475, 95%CI, 0.1865-0.6414, p=0.0009). Adequate sleeping and dietary intake of some foods materially decreased the metabolic syndrome.
