People with psoriasis or psoriatic arthritis who have larger body sizes tend to report more difficulty with daily activities, as measured by standard health questionnaires.

Scientific Claim

Higher whole-body volume is associated with higher Health Assessment Questionnaire (HAQ) scores (Pearson correlation = 0.499) in psoriatic disease patients.

Original Statement

“those with a higher MRI-derived body volume had a higher HAQ score (Pearson correlation = 0.499)”

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

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study is observational, so 'associated with' correctly reflects the correlational nature of the finding without implying causation.

Similar Assertions

People with psoriasis or psoriatic arthritis have about 6% more fat around their internal organs than people without these conditions, even when they have the same body weight.

76%

More visceral fat in psoriasis patients is linked to worse cholesterol profiles, increasing heart disease risk.

75%

People with psoriasis or psoriatic arthritis have slightly more fat under the skin than healthy people with similar body weight, though this difference is not statistically significant.

74%

More visceral fat in people with psoriasis is linked to higher insulin resistance, a key factor in diabetes risk, based on statistical analysis of the data.
