Outline
To investigate the impact of green space exposure on adverse treatment outcomes among newly diagnosed pulmonary tuberculosis patients in Suzhou.
Data from 18 502 newly treated pulmonary TB patients in Suzhou between January 1, 2014 and December 31, 2021 were collected. Green space exposure was quantified using the Normalized Difference Vegetation Index（NDVI）within 250-meter and 500-meter buffer zones around residential addresses. Cox proportional hazards regression models were applied to assess associations between green space exposure and adverse outcomes, adjusting for individual- and environmental-level covariates.
Among patients residing in high nighttime light（NTL）intensity areas, those in the highest quartiles（Q4 and Q5）of green space exposure within the 250-meter buffer exhibited significantly lower risks of adverse outcomes after covariate adjustment, with hazard ratios（HRs）of 0.692（95% CI: 0.487-0.984）and 0.353（95% CI: 0.183-0.683）, respectively. In the 500-meter buffer, stronger protective effects were observed, with HRs of 0.587（95% CI: 0.396-0.869）for Q4 and 0.212（95% CI: 0.078-0.582）for Q5. Wald tests for linear trends confirmed a dose-response relationship（Ptrend<0.05）. Subgroup analyses revealed greater benefits of green space exposure for females, younger patients, indoor workers, urban residents, and clinically diagnosed cases.
Increased green space exposure is associated with reduced risks of adverse treatment outcomes among newly diagnosed PTB patients in high-NTL areas, underscoring its potential public health significance in tuberculosis management.
