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.

Scientific Claim

Waist circumference cut-off values of 83.5 cm for males and 77.5 cm for females are optimal for predicting three or more metabolic risk factors in elderly Chinese.

Original Statement

“The optimal cut-off values of BMI, WC and WHtR in males were, respectively, 24.12 kg/m², 83.5 cm and 0.51, while in females, the values were 23.53 kg/m² and 77.5 cm.”

Assessment Explanation

The study describes observed cut-off values without causal claims; 'optimal cut-off' is a standard statistical term for observational data.

More Accurate Statement

“Waist circumference cut-off values of 83.5 cm for males and 77.5 cm for females are associated with optimal prediction of three or more metabolic risk factors in elderly Chinese.”

Similar Assertions

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.

88%

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.

87%

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.

84%

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.

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.
