研究目的:

本项目拟依托儿童青少年健康队列研究、空气过滤随机对照研究阐明降低PAHs对血压的影响,并明确LRAT介导的PC代谢调控在PAHs致儿童高血压中的作用。明确空气污染物影响儿童心血管健康的效应及机制,为空气污染介导心血管健康损害提供科学依据,也为儿童心血管疾病早期防治提供重要参考,从而实现成年期慢病防治关口前移。  

Objectives of Study:

This project aims to utilize Southwest China Children and Adolescents Health Cohort (SCCAHC) study and randomized controlled trials on air filtration to elucidate the impact of reducing polycyclic aromatic hydrocarbons (PAHs) on blood pressure. Additionally, it aims to clarify the role of LRAT-mediated regulation of phospholipid metabolism in PAH-induced hypertension in children. Understanding the effects and mechanisms by which air pollutants influence children's cardiovascular health will provide a scientific basis for recognizing air pollution-related cardiovascular damage. Furthermore, this research will serve as an important reference for the early prevention and treatment of cardiovascular diseases in children, ultimately contributing to the prevention and management of chronic diseases in adulthood.
