Measuring belly fat is more useful for understanding health risks in psoriasis patients than just checking body weight.
Scientific Claim
Visceral adipose tissue volume is a stronger predictor of metabolic dysfunction in psoriatic disease than body mass index (BMI) alone.
Original Statement
“This study shows that visceral adipose [a more metabolically active depot] can provide additional value to current measures of obesity such as BMI and waist-to-hip ratio and contribute to the unfavourable metabolic dysfunction seen in psoriatic disease.”
Evidence Quality Assessment
Claim Status
overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study is observational and does not directly compare predictive power of VAT vs BMI. 'Stronger predictor' implies causation or superiority not tested here.
More Accurate Statement
“Visceral adipose tissue volume is associated with metabolic dysfunction in psoriatic disease beyond what is captured by body mass index alone.”
Evidence from Studies

More than skin-deep: visceral fat is strongly associated with disease activity, function and metabolic indices in psoriatic disease
