A growing body of studies have reported the health benefits greenness. However, less is known about potential beneficial effects residential greenness on gut microbiota, which essential to human health. In this study, we aim examine association between and microbiota in a population-based cohort study. We included 1758 participants based China Multi-Ethnic Cohort (CMEC) study collected their stool samples for 16S sequencing derive data. Residential was estimated using satellite-based data enhanced vegetation index (EVI) normalized differential (NDVI) circular buffers 250 m, 500 1000 m. The relationships levels composition measured by standardized α-diversity taxonomic composition, were assessed linear regression Spearman correlation weighted generalized propensity scores. Higher significantly positively associated with α-diversity. Per interquartile range (IQR) increase EVI NDVI buffer m increments 0.995(95% confidence interval (CI): 0.212–1.778) 0.653(95% CI: 0.160–1.146) Shannon index. For higher correlated 29 types microbial composition. increased Firmicutes (r = 0.102, adjusted p value 0.004), dominant microbiota. Increased amounts may support healthy benignly altering These findings suggested that green spaces should be designed diverse ultimately optimize benefits.
