Abstract

OBJECTIVE:

To examine associations between rate of eating and macronutrient and dietary fiber intake, and body mass index (BMI).

DESIGN:

Cross-sectional study.

SUBJECTS:

A total of 1695 18-y-old female Japanese dietetic students.

MEASUREMENTS:

Macronutrient intake (protein, carbohydrate, and fat) and dietary fiber intake were assessed over a 1-month period with a validated, self-administered, diet history questionnaire. Body height and weight and rate of eating (according to five categories) were self-reported.

RESULTS:

Among the nutrients examined, only dietary fiber intake weakly, but significantly, and negatively correlated with BMI in a multiple regression analysis. The rate of eating showed a significant and positive correlation with BMI. The mean BMI was higher by 2.2, 1.5, 1.0, and 0.5 kg/m(2) in the 'very fast', 'relatively fast', 'medium', and 'relatively slow' groups, respectively, compared with the 'very slow' rate of eating group. This correlation remained evident after adjustment for nutrient intake.

CONCLUSIONS:

Rate of eating showed a significant and positive correlation with BMI, whereas only dietary fiber intake showed a weak correlation with BMI.
