Abstract

We examined whether the rate of eating was associated with the body mass index and glycemic control status in Japanese patients with type 2 diabetes (50% women, mean ± SD age 59.4 ± 7.5 years). Rapid eating was significantly associated with body mass index (p = 0.047). The body mass index of those who reported eating quickly was 0.8 kg/m2 higher than in individuals who reported eating at medium speed even after adjustment for known confounders. No significant association was observed between the rate of eating and HbA1c. Our findings suggest an association between self-reported rapid eating and an elevated body mass index in patients with type 2 diabetes.

Highlights

• Rapid eating has been reported to be linked to higher BMI in normal subjects. • We examined this issue in patients with type 2 diabetes. • Rapid eating was associated with an elevated BMI. • Rapid eating was not associated with worsening of HbA1c. • Rapid eating was seen more frequently in our subjects than in normal subjects in other studies.

Introduction

The association of eating habits with risks of obesity and diabetes has been investigated from various viewpoints. Particularly, rapid eating has been reported to be associated with a higher body mass index (BMI) and increased body weight among Western (Gerace & George, 1996) and Japanese populations (Maruyama et al., 2008, Otsuka et al., 2006, Sasaki et al., 2003). Moreover, rapid eating also has been reported to be associated with insulin resistance and metabolic syndrome in apparently healthy subjects without diabetes (Otsuka et al., 2008, Shin et al., 2009). However, it is unclear whether the rate of eating is associated with the degree of obesity or glycemic control in individuals with type 2 diabetes even though rapid eating might lead to chronic postprandial hyperglycemia and therefore be associated with poor glycemic control in diabetic patients (American Diabetes Association, 2010). We examined whether the rate of eating was associated with the BMI and glycemic control status in Japanese patients with type 2 diabetes.

Methods

This was a multicentre cross sectional study. Potential subjects were 762 patients with type 2 diabetes 30–70 years old who received outpatient treatment in 11 clinics in the Japan Diabetes Clinical Data Management Study Group (JDDM) (Kobayashi et al., 2006) from November 2008 to April 2010. Excluded from the study were patients who had been diagnosed as having type 2 diabetes within the previous year because it is unlikely that they had achieved stable glycemic control. Of the 762 patients who

Results

Table 1 shows the characteristics of the study population. Of the subjects, 62.7% reported eating quickly, 30.8% reported eating at a medium rate and 6.5% reported eating slowly. BMI increased with increases in the rate of eating (p = 0.020 for ANOVA; p = 0.020 for trend) while there was no such significant trend for HbA1c.

Multiple regression analysis (Table 2) showed that the BMI was significantly higher in participants in the eating quickly category than in the medium speed category by 0.8 kg/m2

Discussion

The results of our study showed that rapid eating was associated with a higher BMI in patients with type 2 diabetes. To our knowledge, this is the first study to examine the association between the rate of eating and glycemic control in patients with type 2 diabetes; however, HbA1c values were not significantly associated with the rate of eating even after adjustment for confounding variables, including BMI.

The association between eating fast and an increased BMI has been reported in healthy
