摘要

背景绿化暴露与精液质量之间的关系及其内在机制尚不清楚。目的评估绿化暴露与精液质量之间的关系，以及这种关系是否由空气污染物暴露介导。根据患者的居住地址，评估了精液检测前0-90天内300米、400米、800米和1000米缓冲区内的空气污染物平均暴露浓度和绿度指数（归一化差异植被指数（NDVI）和土壤调整植被指数（SAVI））。采用多变量线性混合效应模型评估相关性，并采用中介分析法研究空气污染物暴露和体重指数（BMI）对相关性的影响。在对混杂因素进行调整后，进行性运动与 NDVI400m (β (95 % CI): 1.744 (0.834, 2.655)) 和 SAVI400m (β (95 % CI): 1.484 (0.591, 2.377)) 呈正相关。此外，我们还发现，二氧化氮和一氧化碳暴露在很大程度上介导了绿度暴露与进行性运动之间的部分关联。结论我们的研究结果表明，更多的绿色暴露与更高的精液质量相关，而较低的二氧化氮和一氧化碳暴露水平可以在一定程度上起到中介作用。

Association between residential greenness exposure and semen quality: A retrospective study in China

Background

The association between greenness exposure and semen quality and the underlying mechanism are unclear.

Objectives

To assess the association between greenness exposure and semen quality and whether the association is mediated by air pollutant exposure.

Methods

We collected data from 10,273 men in Zhejiang, China, whose wives received assisted reproductive technology from 2015 to 2021. The mean exposure concentrations of air pollutants and greenness indices (normalized difference vegetation index (NDVI) and the soil-adjusted vegetation index (SAVI)) in the 300 m, 400 m, 800 m, and 1000 m buffer zones were assessed from 0–90 days prior to semen testing on the basis of the patient’s residential address. A multivariate linear mixed-effects model was used to evaluate the associations, and mediation analysis was used to investigate the influences of air pollutant exposure and body mass index (BMI) on the associations.

Results

The average (standard deviation) age of the participants was 33.1 (5.2) years. After adjusting for confounders, progressive motility was positively associated with the NDVI_400m (β (95 % CI): 1.744 (0.834, 2.655)) and SAVI_400m (β (95 % CI): 1.484 (0.591, 2.377)). Furthermore, we found that NO₂ and CO exposure significantly mediated part of the association between greenness exposure and progressive motility. Similar results are observed in the sensitivity analysis.

Conclusions

Our results suggest that greater greenness exposure is associated with higher semen quality and can be partially mediated by lower NO₂ and CO exposure levels.
