Comments about the Chinese body mass index and percent body fat correlation, and cut offs.
It’s nice to read a consice article like this, that presents its data with completeness, and makes decent interpretation and conclusions.
The article says that "In Asians, the new proposed cut-offs for overweight and for obesity are >=23.0 and >=25.0 kg/m2."
Here’s some of their data. I’m particularly interested to point out the relatively high body fat percentages in Hong Kong women, with relatively low BMI values.
|% body fat||18.0%||23.9%||23.5%||22.1%||26.9%||23.0%|
|% body fat||29.7%||32.6%||36.6%||38.5%||39.3%||35.2%|
- "In men, a 25% body fat percentage correspondes to a mean BMI of 24.6. In women, a 35% body fat percentage corresponds to a mean BMI of 22.6."
Ah ha. It appears they are already using 25% (men) and 35% (women) body fat percentage as a definition of obesity. That’s higher (in women) than the often seen 30% criteria, and higher than the 33% that is also reasonably common. Where did they get their 35% criteria? From Deurenberg1.
