A 5% increase in the urinary share of one substance formed from arsenic was linked to 1.62 square centimeters less abdominal muscle area.A 5% increase in the urinary share of one substance formed from arsenic was linked to 1.62 square centimeters less abdominal muscle area.

Cross-sectional · 1,597 peopleMuscle
Who was studied1,597 middle-aged and older US adults
What changedAbdominal muscle area was lower in adults with a higher urinary share of monomethylarsonate, an arsenic metabolite
The catchMuscle fat was inferred from muscle density, a proxy rather than a direct measurement
