Einsatz und Identifikation relevanter Items des Edmonton Obesity Staging Systems (EOSS): Eine systematische Literaturrecherche
Application and Selection of Key Components of the Edmonton Obesity Staging System (EOSS): A Systematic Review of the LiteratureAutoren
Abstract
Ziel der Studie
Adipositas erfordert als chronische Erkrankung eine Diagnostik, die über den Body-Mass-Index (BMI) hinaus geht. Eine Möglichkeit bietet z. B. das Edmonton Obesity Staging System (EOSS), in dem medizinische, funktionelle und psychosoziale Dimensionen berücksichtigt werden. Bislang spielt diese Einteilung in der Versorgung allerdings eine untergeordnete Rolle, weil kein entsprechendes Tool vorliegt.
Methodik
Als Basis für die Entwicklung eines möglichen EOSS-basierten Screening- Instruments erfolgte im Februar 2024 eine systematische Literaturrecherche in PubMed und Web of Science sowie eine ergänzende Referenzrecherche. Eingeschlossen wurden Studien mit Erwachsenen (≥18 Jahre), in denen das EOSS angewendet und konkrete Items zur Zuordnung in die genannten Dimensionen und Schweregrade (I bis IV) vorgenommen wurden. Die identifizierten Items wurden im Tandemverfahren von 2 Expertinnen aus dem Adipositasbündnis Nordrhein-Westfalen (NRW) den 3 EOSS-Dimensionen zugeordnet. Relevante Items, die sich nicht einsortieren ließen, wurden unter Sonstiges zusammengefasst.
Ergebnisse
Insgesamt wurden 70 potenziell relevante Publikationen identifiziert und letztlich 24 Studien eingeschlossen. Aus diesen wurden 101 Items detektiert (medizinisch/internistisch: 48 Items; psychisch: 15 Items; funktionell: 19 Items; sonstige: 19 Items). Die Erhebungsmethoden der Items waren heterogen und umfassten sowohl subjektive Verfahren (Fragebögen, Selbsteinschätzungen, Skalen) als auch objektive Erhebungen durch Laborparameter (z. B. HbA1c) und klinische Diagnosen (z. B. arterielle Hypertonie).
Schlussfolgerung
Zwar bietet das EOSS einen vielversprechenden Ansatz für eine differenzierte Risikoeinschätzung bei Adipositas, wird aber bislang kaum operationalisiert. Der identifizierte Item-Pool und die zugrundeliegenden Erhebungsverfahren stellen eine strukturierte Grundlage für die Entwicklung und Validierung praxisnaher Screening-Instrumente in zukünftigen Studien dar.
Abstract
Objective
Obesity, as a chronic disease, requires diagnostic approaches that go beyond the Body Mass Index (BMI). One option is the Edmonton Obesity Staging System (EOSS), which incorporates medical, functional, and psychosocial dimensions. To date, however, this classification has played only a minor role in clinical practice, as no corresponding tool is available.
Methods
As a basis for developing a potential EOSS-based screening instrument, in February 2024 a systematic literature search was conducted in PubMed and Web of Science, complemented by reference screening. Studies including adults (≥18 years) that applied the EOSS and reported concrete items for allocation to the defined dimensions and severity stages (I–IV) were eligible. The identified items were assigned to the three EOSS dimensions by two experts from the Obesity Alliance North Rhine-Westphalia (NRW) in a tandem procedure. Relevant items that could not be allocated were summarized under “other.”
Results
A total of 70 potentially relevant publications were identified, of which 24 studies were included. From these, 101 items were extracted (medical/internal medicine: 48 items; mental: 15 items; functional: 19 items; other: 19 items). The methods of item assessment were heterogeneous and included both subjective approaches (questionnaires, self-assessments, scales) and objective measures based on laboratory parameters (e. g., HbA1c) and clinical diagnoses (e. g., arterial hypertension).
Conclusion
While the EOSS provides a promising approach for differentiated risk assessment in obesity, it has so far been scarcely operationalized. The identified item pool and the underlying assessment methods offer a structured foundation for the development and validation of practical screening instruments in future studies.
