The structural roots of multimorbidity: social inequalities, health disparities, and systemic challenges in Southern Spain

Low-income and female residents in deprived areas face distinct, overlapping health conditions requiring tailored, equity-focused medical approaches.

This mixed-methods study (n=1592 survey + 18 qualitative interviews) in deprived southern Spain identified five socially stratified multimorbidity patterns, demonstrating that complex multimorbidity disproportionately burdens lower-income and female populations. Findings underscore the need for equity-oriented, integrated chronic care models that incorporate social determinants.

Why it surfaced

Rigorous mixed-methods characterization of multimorbidity social patterning is relevant to population health planning; findings from a deprived region have broader generalizability to similar healthcare settings globally.
