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.

Scientific Claim

Waist-to-hip ratio and body adiposity index have lower predictive ability for metabolic risk factors compared to body mass index, waist circumference, and waist-to-height ratio in elderly Chinese.

Original Statement

“WHpR and BAI had a low predictive ability in both genders. The AUC of BMI, WC and WHtR did not differ in males and were all greater than WHpR and BAI; however, in females, the AUC of BMI and WC did not differ and were greater than for WHtR, WHpR and BAI.”

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study reports comparative predictive ability without causal language; 'lower predictive ability' accurately reflects statistical differences in observational data.

More Accurate Statement

“Waist-to-hip ratio and body adiposity index are associated with lower predictive ability for metabolic risk factors compared to body mass index, waist circumference, and waist-to-height ratio in elderly Chinese.”

Similar Assertions

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.

88%

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.

87%

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.

82%

Older Chinese people without high blood pressure who have a larger waist size (over 90 cm for men or 85 cm for women) are slightly less likely to die from any cause compared to those with normal waist size.

79%

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.
