Even people with a large waist size can have normal levels of internal fat: about 1 in 3 men and women in this study had this, showing waist size isn't always a perfect indicator of visceral fat.

Scientific Claim

Among middle-aged adults with a high waist circumference, approximately 28% of men and 27% of women do not have elevated visceral fat, suggesting waist circumference may overestimate visceral fat in some cases.

Original Statement

“Among individuals with a high waist circumference, 28% of men and 27% of women did not have high VAT”

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The claim states a specific prevalence rate from the study's data, which is appropriate for an observational study. It correctly uses 'do not have' for prevalence and does not overstate causation.

Similar Assertions

Even people with a normal waist size can have too much fat around their organs: about 1 in 4 men and 1 in 12 women in this study had this hidden fat, showing waist size alone isn't always reliable.

95%

Even among people classified as obese by BMI, about 1 in 4 men and 1 in 10 women don't have excess fat around their organs, showing BMI doesn't always reflect internal fat levels.

83%

In a group of middle-aged people, about 3 out of 10 women and men have too much fat under the skin of the belly, while about 4 out of 10 have too much fat around their internal organs, based on CT scans.

82%

As people get older, they tend to have more fat around their organs and less under the skin, making weight and waist measurements less reliable for detecting health risks in seniors.

80%

Among people with a normal weight (BMI under 30), about 1 in 10 men and 1 in 9 women have too much fat around their internal organs, showing that weight alone doesn't always reveal hidden health risks.
