2 - BMI classification
The sample was divided into groups based on their BMI’s for some of the analysis and
into EDR groups in other analyses depending on which hypothesis was being considered.
Below are the categories and the frequencies of the sample in this study using the U.K
and the U.S BMI percentile categories which differ (as explained in the method section).
Table 3 also includes the BMI categories that are used in this study which are based on
the U.S classification but those at risk of becoming overweight and those classified as
overweight were grouped together.
