In Reply: We did not attribute the association between psoriasis and a sedentary lifestyle exclusively to psoriatic arthritis, as Drs Skolnick and Alexander suggest. We quoted the findings by Herron et al1 that 32% of obese patients with psoriasis reported that arthritis interfered with physical activity, compared with 14% of nonobese participants. That leaves 68% of obese patients with psoriasis who do not report arthritis as interfering with physical activity, and other factors undoubtedly play a role in patients with psoriatic arthritis.
