  "abstract": "Background: Air pollution monitoring remains limited in many regions due to the uneven distribution of ground-based stations. Satellite data from the Copernicus Sentinel-5P mission provide continuous measurements of atmospheric pollutants and allow improved population-level exposure assessment. This study aimed to evaluate the association between satellite-derived air pollution exposure during pregnancy and preterm birth in South-West Oltenia.\n\nMethods: We built a regional dataset of atmospheric pollutants (2019–2023) at administrative unit level. Daily satellite data were processed and summary statistics (minimum, maximum, mean) for each pollutant were computed. For this analysis, NO₂ and O₃ were used. Exposure was defined as the number of months within the 9 months preceding birth in which concentrations exceeded the area-specific mean (>2 to > 6 months), for both mean and maximum values. Birth data from a regional tertiary hospital included 11,945 live births, of which 995 were preterm. Proportions were compared across exposure categories and odds ratios (OR) were estimated.\n\nResults: Preterm births consistently showed higher exposure to months with pollutant levels above local baseline values. For mean NO₂ values above the local average for >2 months, 51% of preterm births were exposed versus 46% of all births (OR = 1.19). For maximum values, the association was stronger (59% vs. 54%; OR = 1.25). Stronger associations were observed for O₃, where 75% of preterm births were exposed compared to 66% of all births (OR≈1.55).\n\nConclusions: Satellite-derived data provide a practical way to assess cumulative exposure to air pollution during pregnancy. Higher exposure was consistently associated with preterm birth, with stronger signals for O₃, suggesting the value of multi-pollutant approaches in future studies. This findings support the integration of satellite-based monitoring into environmental health surveillance in regions with limited ground infrastructure.\n\nKey messages: • Satellite data can support exposure assessment during pregnancy in regions with limited monitoring.\n\n• Higher air pollution exposure, particularly NO2 and O₃, was associated with preterm birth.",
