Development and validation of the BPDKC model for predicting sarcopenic knee osteoarthritis in community-dwelling older adults: a cross-sectional study.

ABSTRACT:

Background

Sarcopenia and knee osteoarthritis frequently coexist as sarcopenic knee osteoarthritis (SPKOA), a clinically significant and burdensome condition among older adults. Despite its high prevalence and functional impact, no validated, practical tool exists for early identification of SPKOA in community settings. This study aimed to develop and internally validate a parsimonious, clinically applicable prediction model for SPKOA risk stratification in community-dwelling older adults.

Methods

We conducted a cross-sectional analysis of 640 community-dwelling adults aged 65-85 years, recruited between March and October 2024 from the Yuyuan Community Health Service Center in Shanghai, China (median age: 71 years; 57% female). SPKOA was diagnosed using established criteria
