Obese children more likely to develop psoriasis

This large-scale Korean cohort study of children provided evidence that higher BMI was linked to an increased risk of developing AA, AD, and psoriasis among children.

Whether childhood obesity or weight gain leads to the development of pediatric immune-mediated skin diseases remains unclear. We aimed to determine the associations between body mass index or body mass index changes and the development of 3 main immune-mediated skin diseases—alopecia areata, atopic dermatitis (AD), and psoriasis—by analyzing a longitudinal cohort of 2,161,900 Korean children from 2009 to 2020.

The findings indicated that children who were obese had a higher risk of pediatric immune-mediated skin diseases than those with normal weight (P for trend < .01). An increase in body mass index was associated with a higher risk of AD, whereas a decrease in body mass index was correlated with a reduced risk of AD.

Children who gained weight, transitioning from normal to overweight, exhibited a higher AD risk than those who maintained a normal weight (adjusted hazard ratio = 1.15, 95% confidence interval = 1.11–1.20). However, those who shifted from being overweight to achieving a normal weight (adjusted hazard ratio = 0.87, 95% confidence interval = 0.81–0.94) had a lower AD risk than children who were overweight who maintained their weight.

In summary, early childhood obesity may increase the risk of pediatric immune-mediated skin diseases like psoriasis. Weight gain may increase AD risk, whereas weight loss may lower the risk.

Interesting .. wonder if it holds any truth for adults as well. I didn't have psoriasis as a child, nor was I overweight in any way. However, I did become overweight in my 40's and obese (I hate that word, I mean the actual word... dunno why) in my 50's and it was then that I started having psoriasis. I don't think one caused the other, just seems everything else is tied to be overweight.

I know that's not true of you guys, just wondering if there was any correlation in adults.

I wasn't obese as a child (and I hate that word too) I was 25 slim and very fit when I first got psoriases and 30 when I got psoriatic arthritis.

Not much help with the study but yes my doctors tell me I'm too heavy today, but I reply "I'm happy"
