It is shown in the table published by Cole.

Dear Abdulwahab,

Which one do you mean?

I can find the cut-offs but not the name/concept given to each interval, e.g. overweight, obesity, morbid obesity....Is it the same, i.e. overweight (25-29.9), obesity (30-34.9), morbid obesity (+35)?

Hi Chris, 

For children and adolescents, weight status is commonly defined using BMI classifications, however, these are interpreted according to sex-specific percentiles based on a reference population  such as Cole et al. 1995. In the UK, children and adolescents between the 85th and 94th percentile are classified as overweight, whereas children and adolescents beyond the 95th percentile are classified as being obese. I am not sure of the cutoff points in Sweeden, but I have given an example of how you could write your findings below.

"According to age and sex-specific BMI centiles (Cole et al., 1995) the majority of the SUBJECTS were classified as having a healthy body mass (71.4%), 14.3% were classified as overweight and 14.3% as obese."

Hope this helps. 

Best,

Yes, thank you Benjamin! I have already considered their age (they are between 13 to 16 years old, and their sex). I used the supplementary information (the excel sheet) provided by Cole (2012). I was just wondering how to label (e.g. overweight, obese) the participants according to the different percentiles as this was not clear in the excel sheet. 

Cole" article must be read. I say this for 2nd or 3rd time. All the best.

The centile method is for those under 2 yrs.
