The Claim

In adults aged 50 and older, large absolute waist and hip measurements are associated with an increased risk of type 2 diabetes, irrespective of waist-to-hip ratio classification.

In plain English

Adults aged 50 and older with larger waist and hip measurements have a higher risk of developing type 2 diabetes, even if their waist-to-hip ratio is low or high.

See the scientific wording

In adults aged 50 and older, individuals with large waist and large hip measurements have a higher risk of type 2 diabetes regardless of whether their waist-to-hip ratio is classified as low or high, indicating that absolute fat measurements matter more than their ratio.

Why this might work

When both the waist and hips store large amounts of fat, the fat around the belly releases too many fatty acids into the liver, which blocks insulin from working properly. Even though the fat around the hips and thighs normally helps protect against this by releasing helpful chemicals, the overload from the belly fat is too strong and wins out, leading to high blood sugar and type 2 diabetes.

    Even if two older adults have the same waist-to-hip ratio, the one with a bigger waist and bigger hips is more likely to get type 2 diabetes — so the actual sizes matter more than the ratio.
