A machine learning approach combining the self\u2010organizing maps and K\u2010means clustering was employed to identify multimorbidity patterns. Ordered logistic regression was used to analyze the association between multimorbidity patterns and disability levels.

Older adults with multimorbidity were at greater risk for higher disability levels compared with those without multimorbidity (odds ratio [OR]\u2009=\u20091.679, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Among the identified multimorbidity patterns, the Allomnesia\u2010Arthritis pattern exhibited the highest risk of more severe disability (OR\u2009=\u20093.976, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), followed by the Hypertension\u2010Stroke pattern (OR\u2009=\u20093.745, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001).
