Jørgensen AHR, Aarestrup J, Baker JL, et al. - In this cohort study of 347,200 Danish children (175,750 boys), researchers explored the correlation of birth weight, childhood BMI, change in BMI during childhood, and childhood height with subsequent risks of hidradenitis suppurativa (HS) in adulthood. This investigation involved schoolchildren from the Copenhagen School Health Records Register born from 1930 to 1996 who were linked to the Danish National Patient Register of hospital discharge diagnoses to identify cases of HS. The authors discovered that both the lightest and heaviest babies had increased HS risks. Childhood BMI was positively and significantly linked to the risk of development of HS in adulthood. Such findings indicate that returning to normal prepuberty weight reduces HS risks to levels observed in children who have never been overweight. Childhood height was unrelated to HS risk.
