The Claim

When body mass index and waist circumference are statistically controlled, the association between vegetarian diet and hip bone mineral density is no longer significant.

In plain English

People who follow a vegetarian diet have similar hip bone mineral density as nonvegetarians when their body mass index and waist circumference are taken into account.

See the scientific wording

Body mass index and waist circumference are strong modifiers of the association between vegetarian diet and bone mineral density, such that when these anthropometric factors are accounted for, differences in hip bone density between vegetarians and nonvegetarians become negligible.

Why this might work

People with lower body weight and smaller waistlines put less physical pressure on their bones, especially in the hips. This reduced pressure signals the bones to slow down the process of building new bone tissue, leading to lower bone density. Vegetarians often have lower body weight and smaller waists, which explains why their hip bone density appears lower — once body size is accounted for, the diet itself does not further reduce bone density.

    Vegetarians tend to have slightly lower hip bone density, but this is mostly because they tend to be thinner and have smaller waists — once you account for body size, the difference in bone density almost disappears.
