For older Chinese men, waist size is the best measure for predicting high triglycerides, but for women, BMI works better.

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.

For older Chinese men, measuring body mass index, waist size, or waist-to-height ratio all work about equally well to predict if someone has three or more health risks like high blood pressure or diabetes.

Older Chinese people with high blood pressure who have a larger waist size (over 90 cm for men or 85 cm for women) are less likely to die from any cause compared to those with normal waist size.

BMI is the best body measurement for predicting high blood pressure in older Chinese men and women compared to other measurements.
