Background

Optimizing nutritional care for people with multimorbidity requires effective and feasible tools for early risk identification.

Purpose

This study aimed to investigate the associations of conicity index (C-index) and body roundness index (body roundness index) with multimorbidity among adults in Guangzhou, and to explore their potential utility in identifying individuals who may benefit from prioritized nutritional assessment.

Methods

Based on the Fourth Adult Chronic Disease and Risk Factor Surveillance Program in Guangzhou, a total of 15,532 adults were recruited in this cross-sectional study.

n = 15,532 adults

Results

higher body roundness roughly triples the odds of multimorbidity

OR 3.05 (95% CI 2.74 to 3.41)

CI excludes the null - significant

More results

The prevalence of multimorbidity was 38.95%.

Higher C-index and body roundness index quartiles were significantly associated with increased multimorbidity risk.

A dose-response relationship was observed ( p < 0.001).

More results

Body roundness index showed statistically significantly higher discriminative ability relative to traditional anthropometric indices, though its overall discriminative performance was modest (AUC = 0.678).

Conclusion · 1 of 2

C-index and body roundness index are strongly and positively associated with multimorbidity.

Conclusion · 2 of 2

These simple, non-invasive indices may support community-based risk stratification and help identify individuals who warrant further clinical and nutritional assessment.
