Using all three body measurements together doesn't help spot kids at risk better than using just one of them alone.

Overweight kids 8-17 are 2.6-3.5 times more likely to have heart/metabolic risks, and obese kids are about 14 times more likely, compared to normal-weight peers.

In kids 8-17, these body measurements are much better at predicting heart/metabolic risks in overweight or obese children than in those with normal weight, with stronger links in the higher weight groups.

For kids 8-17, these body measurements are better at correctly identifying those who don't have heart/metabolic risks (high specificity) than those who do (low sensitivity), leading to many missed cases.

For kids and teens aged 8 to 17, measuring body mass index, waist size, or waist-to-height ratio all show similar ability to spot those at risk for heart and metabolic problems, with accuracy scores between 0.70 and 0.74.

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

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 women, waist-to-height ratio is the best body measurement for predicting high uric acid levels.

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

BMI is the best measure for predicting fatty liver disease in older Chinese men and women compared to other body measurements.

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.

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

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, 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.

In men with spinal cord injuries, waist size strongly correlates with total body fat and belly fat, indicating it's a good measure of overall fatness.

In men with spinal cord injuries, larger waist sizes are linked to higher heart disease risk scores, older age, higher cholesterol, higher blood pressure, and smoking.

Using a waist size of 86.5 cm instead of general cutoffs identifies about 1.5 times more men with spinal cord injuries as having metabolic syndrome across different diagnostic criteria.

For men with spinal cord injuries, a waist size of 86.5 cm corresponds to a lower heart disease risk threshold (6 instead of 10), identifying more people at risk.

Using a waist size of 86.5 cm instead of standard cutoffs makes different doctors agree much more on who has metabolic syndrome in men with spinal cord injuries (Kappa 0.95 vs 0.47).

For men with spinal cord injuries, a waist size of 86.5 cm better detects belly fat (visceral adipose tissue) than the standard cutoff, identifying more true cases (84.6% vs 7.7%) while still correctly identifying most people without excess belly fat (91.3% vs 100%).

Using a waist size of 86.5 cm instead of 102 cm in men with spinal cord injuries better identifies who has obesity based on body fat percentage, catching more true cases (68.8% vs 6.3%) while still correctly identifying most non-obese people (90% vs 100%).

For men with spinal cord injuries, using a waist size of 86.5 cm instead of 102 cm identifies more people as obese (36% vs 3%), which is a big difference.

For some age and gender groups in the Pacific islands, the waist size cutoff for the skin condition acanthosis nigricans is lower than the standard cutoff recommended by the International Diabetes Federation.
