sicknessrelated

Sicknessrelated is a nonstandard compound adjective that denotes a relationship to sickness or illness. In standard English, the preferred forms are sickness-related or illness-related, depending on context. The single-word form “sicknessrelated” is uncommon outside coding, data fields, and some informal writing, and may be flagged as nonstandard in formal style guides.

Common applications appear in health informatics, epidemiology, occupational health, and patient-reported outcomes. For example, sickness-related absenteeism describes days away from work attributable to illness; sickness-related symptoms refers to symptoms arising from disease; and sickness-related quality of life captures how illness affects daily functioning.

Alternatives and guidance: Use illness-related or disease-related when describing specific conditions; reserve sickness-related for contexts where the term clearly refers to sickness in general or when the sources use this exact phrasing. When documenting datasets, use consistent naming conventions; if the term is present as an identifier, ensure it is defined in metadata.

Notes: The term has no widely recognized definition independent of context; readers should rely on accompanying definition to avoid ambiguity. Etymology traces to a combination of “sickness” and “related,” mirroring wider compound adjectives such as “illness-related.”
