About this reference

Ramirez-Velez and colleagues analysed anthropometric data from ENSIN 2010, Colombia's national nutrition survey, and produced sex-specific smoothed percentile tables for waist circumference and waist-to-height ratio across 5-year adult age brackets. The sample is very large and population-based, making it one of the few published adult datasets with direct WHtR centiles rather than only risk cutoffs.

Known limitations

Colombian population only, so absolute values may not match US, UK, German, or other populations with different average waist size, height, and obesity prevalence
Age range is limited to 20 to 64 years; no older-adult reference values are provided
The published table reports P3, P10, P25, P50, P75, P90, and P97; this site uses P3 and P97 as practical proxies for P5 and P95
