Diaper Use Increases the Risk of Buttock and Perineal Abscesses

Over the last decade, there has been a notable increase in the incidence of abscesses. Children in the diaper-wearing age group are disproportionately affected, and most of these abscesses occur in the buttock and perineal region. Using case-control methodology, we sought to determine if diaper use itself is an independent risk factor for abscess formation.Cases were patients, at least 2 years of age but less than 4 years, who presented to the emergency department with a complaint of a buttock or perineal abscess. Age-matched controls presented to the emergency department for unrelated reasons. Caregivers of subjects responded to a survey regarding diaper use (toilet trained, for sleep only, or all day), type and brand of diaper, and diaper hygiene-related factors.We enrolled 465 patients (93 cases, 372 controls). Fully toilet trained children were less likely to have buttock and perineal abscess than their sleep-only and all-day diaper-wearing peers. Limiting diaper use to naptime and overnights (sleep only) did not confer protection against abscesses. Diaper hygiene-related factors did not affect the risk of abscess formation. Female sex was also identified as a strong risk factor for buttock and perineal abscess formation.Diaper use is a potentially modifiable risk factor for buttock and perineal abscess formation in young children.
