Analysis population

Away from 2,087 first-seasons people whom underwent an over-all examination (pre-university) and you can finished surveys within Fitness Provider Cardio away from Okayama School in , step one,396 pupils volunteered to receive good step three-season go after-right up examination before graduation during the (follow-up rate; 66.9%). Because of it analysis, we felt users having an effective Body mass index away from ? twenty five.0 kg m ?dos as the fat (16) . I excluded 82 people who had been overweight (Bmi ? twenty five kg meters ?dos ) within its standard wellness test. Ultimately, research from 1,314 pupils (676 men and you will 638 women; 65.3%) have been assessed. The research are approved by the Integrity Committee of Okayama College Graduate School off Drug, Oral and Drug Sciences (No. 306). Composed concur was extracted from every players.

Review regarding overweight/carrying excess fat

On the general health test, the peak and the entire body pounds off participants was counted because of the university’s personal health nurses utilizing the Tanita excess fat analyser (Design No. BF-220; Tanita, Tokyo, Japan). Bmi was determined because the weight in kilograms split up of the peak inside the m squared (23) .

Survey

Participants reported rate out of eating in line with anybody else, according to one of four qualitative classes: slow, regular, quick, and also quick. New validity and you can reliability of one’s questionnaire has already been confirmed and you will useful comparing relationships anywhere between thinking-said food rate and you may carrying excess fat (24) . I shared timely and also punctual answers towards a single class away from eating easily and you can sluggish and you may normal responses for the just one group of dining slow (8) .

Some other lifestyle factors, responses got because of the members for the an effective “yes/no” format the following: an irregular diet plan (we.age., unusual mealtime), missing morning meal, restaurants up until full, frequently snacking and you can/or eating at night, seem to sipping unhealthy fats, seem to eating greens, frequently dinner unhealthy foods, apparently dining chocolate, seem to ingesting (sugar-sweetened) carbonated drinks, regular physical exercise, and you can chronic taking (sixteen, 20) . The fresh survey are used at standard.

Mathematical research

Paired t, unpaired t, Fisher’s exact, and chi-squared tests were used to determine whether there were any significant differences between baseline and re-examination, or normal weight and overweight groups. Using a logistic regression model, both odds ratio (OR) and 95% confidence interval (CI) were calculated. Being overweight at the 3-year follow-up was used as a dependent variable. Gender, eating quickly, and frequently consuming fatty foods at baseline were added as independent variables on multivariate analysis according to the guidelines of a previous study (25) . All data were analyzed using the Statistical Package for the Social Sciences (21.0J for Windows; SPSS Japan, Tokyo, Japan). A P < 0.05 was considered statistically significant.

Results

There were no significant differences in prevalence of eating quickly and body composition at baseline between participants who were followed up and those who were not (data not shown). Table 1 shows the characteristics of participants. Overall, 207 male (30.2%) and 198 female (31.0%) participants reported eating quickly. Of the 38 participants (2.9%) who became overweight, none were obese (BMI ? 30 kg m ?2 ). There was a significant difference in body composition between baseline and re-examination data (P < 0.05).

In both male and female participants, a higher prevalence of those who ate quickly was observed in the overweight group compared with the normal weight group (P < 0.05). The prevalence of participants who ate quickly and frequently consumed fatty foods was significantly higher in the overweight group than in the normal weight group (P < 0.05).
