UK Biobank study compares count-based and clustering definitions of multimorbidity and their association with prevalence, health profiles, and mortality

Summary

This cohort study using UK Biobank data (n=474,397) compares different definitions of multimorbidity—count-based approaches (using various condition lists and thresholds of ≥2 or ≥3 conditions) versus clustering analysis to identify subtypes. The study evaluates how these different definitions affect the estimated prevalence of multimorbidity, associated health profiles, and mortality outcomes. The research aims to understand how methodological choices in defining multimorbidity influence research findings and clinical implications.
