Statistical 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) .
