Key Message
The study of 3518 adults across 9 Iranian provinces revealed significant pro-poor socioeconomic inequality in health-related quality of life (HRQoL), with worse HRQoL concentrated among lower-income groups (concentration index: -0.116).
Income (38%) and education level (31.53%) were the largest contributors to this inequality, followed by age (8.05%) and physical activity (7.30%) based on decomposition analysis.
All five EQ-5D-5L health dimensions showed more reported problems in lower socioeconomic groups, emphasizing the need for targeted interventions addressing income, education, and lifestyle factors to reduce HRQoL disparities in Iran.
