Deren prevalence data on child thinness, overweight and obesity
Age-sex-specific prevalence rates of thinness, overweight and obesity in Ukraine children based on body mass index and IOTF, WHO and CDC cut-offs.
deren
A tibble with 22 observations on the following 11 variables:
postnatal age from 7 to 17 completed years
two-level factor - Boys and Girls
thinness prevalence based on IOTF reference and 18.5 cutoff
thinness prevalence based on WHO reference and -2 cutoff
thinness prevalence based on CDC reference and 5 cutoff
overweight prevalence based on IOTF reference and 25 cutoff
overweight prevalence based on WHO reference and +1 cutoff
overweight prevalence based on CDC reference and 85 cutoff
obesity prevalence based on IOTF reference and 30 cutoff
obesity prevalence based on WHO reference and +2 cutoff
obesity prevalence based on CDC reference and 95 cutoff
Note that the overweight prevalences are for overweight not obesity, i.e. the prevalence between the overweight and obesity cutoffs.
The values are obtained from Table 2 of Deren et al (2020). https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0244300.
