Background: Metabolic syndrome has received increased global attention over the past few years. Eating behaviors, particularly eating speed, have long been of interest as factors that contribute to the development of obesity and diabetes. The aim of this study was to assess the relationship between eating speed and incidence of metabolic syndrome among middle-aged and elderly Japanese people.Methods: A total of 8941 community residents from Soka City in Saitama Prefecture, aged from 40 to 75 years and without a diagnosis of metabolic syndrome, participated in the baseline survey in 2008 and were followed until 2011. Anthropometric measurements and lifestyle factors were measured at baseline and follow-up. The association between eating speed and incidence of metabolic syndrome was evaluated using Cox proportional hazards models adjusted for potential confounding variables.Results: During the 3-year follow-up, 647 people were diagnosed with metabolic syndrome (25.0 cases/1000 person-years). The incidence rates of metabolic syndrome among non-fast-eating and fast-eating participants were 2.3% and 3.1%, respectively. The multivariate-adjusted hazard ratio for incidence of metabolic syndrome in the fast-eating group compared to the not-fast-eating group was 1.30 (95% confidence interval [CI], 1.05–1.60) after adjustment for the potential confounding factors. Eating speed was significantly correlated with waist circumference and high-density lipoprotein cholesterol (HDL-C) components of metabolic risk factors. Hazard ratios in the fast-eating group compared with the reference group were 1.35 (95% CI, 1.10–1.66) for waist circumference and 1.37 (95% CI, 1.12–1.67) for HDL-C.Conclusions: Eating speed was associated with the incidence of metabolic syndrome. Eating slowly is therefore suggested to be an important lifestyle factor for preventing metabolic syndrome among the Japanese.

There have been few epidemiological studies on recurrent sickness absence due to depression after returning to work (RTW). The objective of this study was to investigate the prognosis of workers who are RTW with depression in a Japanese company. This study employed a descriptive epidemiology study design. Subjects of this study were 540 employees who worked full-time and were registered in the Health Data System and returned to work from April 2002 to March 2008 after their first leave of absence due to depression. We investigated the recurrence of sickness absence due to depression after returning to work using the Kaplan-Meier survival curve method. During the 8.5 yr follow-up period, almost half of the RTW employees experienced recurrent sickness absence. There was a steep increase in recurrent rates the first two years after RTW, and 85.2% of total recurrence of sickness absence had occurred within three years after the index episode.
