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.

Scientific Claim

The optimal body mass index cut-off value for predicting three or more metabolic risk factors in elderly Chinese males is 24.12 kg/m² and 23.53 kg/m² in females.

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 implying causation; 'optimal cut-off value' is a descriptive statistical term appropriate for observational data.

Similar Assertions

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.

84%

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.

84%

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.

79%

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

77%

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.
