Dust storms are considered one of the most critical environmental challenges affecting Middle Eastern cities, particularly Baghdad, causing serious impacts on public health, urban livability, and environmental sustainability. In this context, sustainable housing can play a significant role in mitigating the negative effects of dust storms and enhancing the principles of a healthy city. The main objective of this study is to model the relationship between sustainable housing, dust impact, and healthy city using a structural equation modeling approach. This study is applied in purpose and adopts a descriptive-analytical research design. The statistical population consists of citizens of Baghdad, and the sample includes 384 respondents, selected through random sampling. Data were collected using a researcher-designed questionnaire and analyzed using SmartPLS software and the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique. Reliability and convergent validity were confirmed through Cronbach's alpha, composite reliability, and average variance extracted (AVE). The findings reveal that sustainable housing has a significant negative effect on dust impact (β = -0.795), while dust impact has a significant negative effect on the healthy city (β = -0.477). In addition, sustainable housing has a significant positive effect on the healthy city (β = 0.411). Bootstrapping results indicate that all structural paths are statistically significant at the 99% confidence level, and the Q² values (0.427 for dust impact and 0.478 for healthy city) demonstrate adequate predictive relevance of the research model. Overall, the results highlight the importance of sustainable housing a for reducing environmental vulnerability and improving citizens' health in dust-prone cities.
