Abstract:
Objective:To explore the association between greenspace morphology and the risk of severe fever with thrombocytopenia syndrome (SFTS) in Shandong Province.Methods:The SFTS cases data and land use data in Shandong province from 2018 to 2022 were collected, 6 landscape indices were calculated through Fragstats 4.2 software, and a negative binomial regression model was used to quantitatively evaluate the effect. Meteorological and socioeconomic factors during the same period were controlled as covariates. Subgroup analysis were conducted by age, gender and occupation. The percentage of relative risk[(RR-1)×100%] with 95% confidence interval (95% CI) was used as effect estimates. Results:There was a significant association between greenspace morphology and the risk of SFTS. Every 1% increase in the percentage, the mean area, fragmentation, aggregation, connectedness, and complexity of the shape of greenspace will lead to an increase in the risk of SFTS by 4.28% (95% CI: 2.88%-5.68%), 3.56% (95% CI: 1.06%-6.12%), 2.43% (95% CI: 1.38%-3.61%), 2.22% (95% CI: 1.39%-3.11%), 0.41% (95% CI: 0.26%-0.56%), 0.26% (95% CI: 0.10%-0.41%), respectively. There were statistically significant differences in the association between greenspace morphology and the risk of SFTS among different age and occupational subgroups. The elderly and farmers were the more susceptible to the changes in the percentage of greenspace and the complexity of the shape of greenspace. Conclusions:Greenspace morphology is related to the risk of SFTS. The elderly and farmers are vulnerable populations.
