Abstract 4119: High Consumptions of Fish, Dairy Products and Cereals are Associated with Low Prevalence of Metabolic Syndrome
Objectives: Previous reports have associated dairy product intake with low incidence of metabolic syndrome. However, consumption of dairy products is linked to other eating patterns which may confound the effects of dairy intake. The aim of this work was to analyse the relationship of fish, dairy product and cereal intakes with metabolic syndrome.
Methods: A sample of 912 men aged 45– 64 years was randomly selected from the general population, as part of the last French MONICA Cross-sectional Survey on cardiovascular risk factors. Each participant completed a three-consecutive-day food record. Waist circumference and blood pressure were measured according to standardised protocols. A fasting blood sample was taken for lipid and glucose measurements. Metabolic syndrome was assessed according to the NCEP ATP III definition.
Results: The prevalence of metabolic syndrome was 23.5% in the whole sample. When the intakes of fish, dairy products and cereals were below the median value in the sample, the prevalence was 29.0%, 28.1% and 28.1%, respectively, and significantly lower (p=0.001), when the intakes were above the median (18.4%, 18.9% and 18.9%). When the three intakes were all above the median, the prevalence was 13.1%, versus 37.9% when they were all below. In multivariate logistic regression analysis adjusted for centre of inclusion, age, physical activity, education level, smoking, antihypertensive and hypocholesterolemic drug use, energy intake, alcohol consumption, dieting and diet quality index, the odds ratio (OR) to have a metabolic syndrome was 0.50 (95% confidence interval: [0.36–0.71]) for subjects with fish intake above the median as compared with those below. It was 0.67 [0.47– 0.94] for dairy products and 0.69 [0.47–1.01] for cereals. When the intakes of fish, dairy products and cereals were all above the median (as compared with all below), the OR to have a metabolic syndrome was 0.21 [0.10 – 0.44].
Conclusion: Dietary behaviours characterised by a high consumption of fish, dairy products and cereals are associated with a lower probability to present with a metabolic syndrome, independently of the level of other environmental factors. The combination of these food intakes tends to be more favourable than the consumption of each one separately.
