Cross-sectional and longitudinal analysis reveals impact of chronic disease comorbidity on healthcare use among older adults, suggesting targeted interventions.

Key Points

This study aims to analyze the impact of chronic disease comorbidity on healthcare utilization among older adults in China.
Cross-sectional analysis using 2020 data from 8,316 adults aged ≥ 60 employed multivariable logistic and zero-inflated negative binomial regression.
Longitudinal analysis followed 1,178 participants from 2011 to 2020, utilizing latent class growth model to identify disease accumulation trajectories.
Evaluated dynamic impacts of disease number changes on service use with binary and ordered logistic regressions.
Comorbidity rate among Chinese elderly (≥ 60) was 66.7%; increasing disease numbers significantly raised outpatient and inpatient service utilization.
Four distinct chronic disease development trajectories identified, with those on higher increment trajectories facing greater healthcare utilization risks.
Higher baseline disease counts predicted an increased risk of accumulating additional diseases.
