Abstract 20249: Slow Down, You Eat Too Fast: Fast Eating Associate With Obesity and Future Prevalence of Metabolic Syndrome
Introduction: Metabolic syndrome (Mets) is one of the cause of cardiovascular diseases. Several reports have showed associations between eating speed and incidence of weight gain. Limited information, however, is available concerning the relation between eating speed and the risk of prevalence of Mets.
Hypothesis: The aim of this study was to evaluate whether eating speed and future prevalence of Mets.
Methods: We evaluated 1083 subjects (642 male subjects, 441 female subjects; mean age 51.2 years) who underwent health examination programs in 2008 and 2013, who were free of Metabolic Syndrome in 2008. Mets was defined on the basis of criteria that was authorized by the Japanese Committee on the Criteria for Mets. We divided the participants into three eating-speed categories as follows: slow, normal and fast. Information on lifestyle factors, such as dietary behaviors, and physical activity, as well as medical history, were obtained by a self-administered questionnaire at the baseline. Weight gain was defined as gained over 10 kg from their weight at age 20.
Results: During the 5-year follow-up, 84 people were diagnosed with metabolic syndrome. The incidence rates of metabolic syndrome among slow, normal and fast-eating participants were 2.3, 6.5 and 11.6%, respectively. The multivariate-adjusted hazard ratio for incidence of metabolic syndrome in the fast-eating group compared to the normal and slow group was 1.89 (95% confidence interval [CI], 1.21-2.98, p<0.05), 5.49 (95% confidence interval [CI], 1.30-23.3, p<0.05). Eating speed was significantly correlated with weight gain, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C) components of metabolic risk factors. Multivariable logistic analysis revealed that weight gain and TG and HDL-C was significantly associated with Mets cumulative incidence (OR 3.59: 95% CI: 2.12-6.09, p<0.001, OR 1.003: 95% CI: 1.001-1.004, p<0.001, OR 0.96: 95% CI:0.935-0.980, p<0.005).
Conclusions: Eating speed was associated with obesity and future prevalence of Metabolic syndrome. Eating slowly may therefore indicated to be a crucial lifestyle factor for preventing metabolic syndrome among the Japanese.
