Jørgensen AHR, Aarestrup J, Baker JL, et al. - In a large Danish population-based cohort, researchers sought to explore the correlation of birth weight, childhood BMI, change in BMI during childhood, and childhood height with subsequent risks of hidradenitis suppurativa (HS) in adulthood. The sample consisted of 347,200 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 risks of HS. Childhood BMI was positively and significantly related to the adult risk of developing HS. Such results indicate that returning to normal weight before puberty decreases the risk of HS to levels found in never-overweight children. Childhood height was not linked to HS risk.
