For older Chinese women, body mass index and waist size are equally good at predicting multiple health risks, but waist-to-height ratio is slightly less accurate.

For older Chinese men, a waist size of 83.5 cm is the best threshold to spot multiple health risks, while for women, it's 77.5 cm.

Measuring waist-to-hip ratio or body fat index is less useful for predicting health risks in older Chinese people than BMI, waist size, or waist-to-height ratio.

Nearly half of older Chinese people in this study had multiple health risks like high blood pressure or diabetes, with slightly more women affected than men.

For older Chinese men, a BMI of 24.12 is the best threshold to identify those with multiple health risks, while for women, it's 23.53.
