Abstract

Fine particulate matter (PM2.5) is a known risk factor for heart failure (HF), while plant-based dietary patterns may help reduce HF risk. This study examined the combined impact of PM2.5 exposure and a plant-based diet on HF incidence. A total of 190,092 participants from the UK Biobank were included in this study. HF cases were identified through linkage to the UK National Health Services register, with follow-up lasting until October 2022 in England, August 2022 in Scotland, and May 2022 in Wales. Annual mean PM2.5 concentration was obtained using a land use regression model, while the healthful plant-based diet index (hPDI) was calculated using the Oxford WebQ tool based on two or more 24-hour dietary assessments of 17 major food groups. Cox proportional hazard models assessed the associations of PM2.5 and hPDI with HF risk, and interactions were evaluated on additive and multiplicative scales. During a median of 13.4-year follow-up, 4,351 HF cases were recorded. Participants in the highest PM2.5 tertile had a 23% increased HF risk (HR: 1.23, 95% CI: 1.14-1.32) compared to those in the lowest tertile. Moderate or high hPDI was associated with reduced HF risk relative to low hPDI. The lowest HF risk was observed in individuals with high hPDI and low PM2.5 exposure, underscoring the protective role of a plant-based diet, particularly in areas with lower PM2.5 levels. A healthy plant-based diet may mitigate HF risk, especially in populations exposed to lower PM2.5 levels.

健康的植物性饮食模式、PM2.5暴露和心力衰竭风险:一项基于人群的队列研究
细颗粒物(PM2.5)是心力衰竭(HF)的已知危险因素,而植物性饮食模式可能有助于降低心力衰竭风险。本研究考察了PM2.5暴露和植物性饮食对心衰发病率的综合影响。来自英国生物银行的190,092名参与者被纳入了这项研究。通过与英国国家卫生服务登记处的联系确定HF病例,随访持续到2022年10月在英格兰,2022年8月在苏格兰,2022年5月在威尔士。PM2.5的年平均浓度采用土地利用回归模型计算,健康植物性饮食指数(hPDI)采用牛津WebQ工具计算,基于对17种主要食物类别的两次或多次24小时饮食评估。Cox比例风险模型评估了PM2.5和hPDI与HF风险的关联,并在相加和相乘尺度上评估了相互作用。在中位13.4年的随访期间,记录了4351例心衰病例。PM2.5浓度最高的参与者与PM2.5浓度最低的参与者相比,HF风险增加23% (HR: 1.23, 95% CI: 1.14-1.32)。相对于低hPDI,中等或高hPDI与HF风险降低相关。在高hPDI和低PM2.5暴露的个体中观察到最低的HF风险,强调了植物性饮食的保护作用,特别是在PM2.5水平较低的地区。健康的植物性饮食可降低心衰风险,特别是暴露于PM2.5水平较低的人群。
