Adult diaper
diaper made to be worn by a person with a body larger than that of an infant or toddler
An adult diaper (or adult nappy in Australian English, British English, and Hiberno-English) is a diaper made to be worn by a person with a body larger than that of an infant or toddler. Diapers can be necessary for children, adolescents and adults with various conditions, such as incontinence, mobility impairment, severe diarrhea or dementia. Adult diapers are made in various forms, including those resembling traditional child diapers, underpants, and pads resembling sanitary napkins (known as incontinence pads). Superabsorbent polymer is primarily used to absorb bodily wastes and liquids.
Alternative terms such as "briefs", "incontinence briefs", or "incontinence products" are also used.

Why this record matters
The subject matters to the general reference register because the source frames it as diaper made to be worn by a person with a body larger than that of an infant or toddler. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q860175. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025, 2030, 2022 and 2024.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
