Bộ dữ liệu phân loại BMI ở người trưởng thành theo chuẩn WHO và chuẩn châu Á - Thái Bình Dương do IDI phối hợp với WHO/WPRO, IASO và IOTF công bố. Chuẩn châu Á sử dụng các ngưỡng thấp hơn để nhận diện thừa cân, béo phì và các mức nguy cơ sức khỏe.

## Highlights

- **Ngưỡng thừa cân WHO:** 25 kg/m² BMI — Người trưởng thành
- **Ngưỡng thừa cân châu Á:** 23 kg/m² BMI — Chuẩn châu Á - Thái Bình Dương
- **Ngưỡng béo phì châu Á:** 25 kg/m² BMI — Chuẩn châu Á - Thái Bình Dương
