生物多样性已被公认为对人类健康和福祉的积极贡献者。心血管疾病和癌症是全球最重要的两种健康负担，了解它们与生物多样性的关系是促进生物多样性保护和人类健康的重要一步。鸟类的物种丰富度是生物多样性的一个共同指标，因为它们数量庞大、分布独特，以及对环境干扰的敏锐敏感性。这项生态研究利用了来自 eBird 数据库的鸟类观测数据、来自国际健康指标和评估的人类健康数据以及县级统计数据，包括人口特征、社会经济、医疗保健服务、居住环境以及地理和气候特征。 2014 年。我们的目标是广泛探索美国 (US) 不同类型癌症（29 种疾病）和心血管疾病（10 种疾病）的生物多样性（即鸟类物种丰富度）与年龄标准化特定原因死亡率之间的个体关联。我们根据各种社会人口和地理因素进行的多元回归分析表明，鸟类稀有物种丰富度的增加与五种最常见癌症中的三种癌症（即气管癌、支气管癌和肺癌）死亡率的降低相关。乳腺癌（仅限女性）、结肠癌和直肠癌。对于心血管疾病，缺血性心脏病和脑血管疾病（两种最常见的死亡原因）也观察到类似的关系。这项研究提供了有关生物多样性对人类健康有益影响的详细信息。版权所有 © 2024 Xu、Qu、Li 和 Chen。

Biodiversity has been recognized as a positive contributor to human health and wellbeing. Cardiovascular disease and cancer are the two most significant global health burdens, and understanding their relationship with biodiversity forms an essential step toward promoting biodiversity conservation and human health.The species richness of birds is a common indicator of biodiversity, given their vast numbers, distinctive distribution, and acute sensitivity to environmental disturbances. This ecological study utilized avian observation data derived from the eBird database, human health data from the International Health Metrics and Evaluation, and county-level statistics, including population characteristics, socio-economics, healthcare service, residential environment, and geographic and climatic characteristics in 2014. We aimed to extensively explore the individual associations between biodiversity (i.e., avian species richness) and age-standardized cause-specific mortalities for different types of cancers (29 conditions) and cardiovascular diseases (10 conditions) across the United States (US).Our multiple regression analyses that adjusted for a variety of socio-demographic and geographical factors showed that increased rarefied species richness of birds was associated with reduced mortality rates for three of the five most common cancers, namely, tracheal, bronchus, and lung cancer, breast cancer (in women only), and colon and rectal cancer. For cardiovascular conditions, a similar relationship was observed for ischemic heart disease and cerebrovascular disease-the two most frequent causes of mortality. This study provided extended details regarding the beneficial effects of biodiversity on human health.Copyright © 2024 Xu, Qu, Li and Chen.
