Analysis of the current status and influencing factors of cardiovascular health in children and adolescents

The pathological origin of cardiovascular disease (CVD) can be traced back to children and adolescents. The younger age and prevalence of its risk factors have become a global public health challenge. This paper systematically analyzes the current severe situation of cardiovascular health in children and adolescents, and points out that obesity, unhealthy lifestyle and health inequality are increasingly prominent, while the traditional prevention and control system has obvious limitations in dynamic risk assessment, multi-source data integration and cross sectoral collaboration. In order to meet these challenges, this paper proposes an innovative path based on artificial intelligence (AI) and multimodal data fusion. By constructing a dynamic risk profile, developing interpretable AI decision support, establishing a "school family community medical" collaborative intervention network, and improving the ethics and privacy protection framework, this paper promotes the transformation of health management to intelligent, accurate and systematic. However, the system still faces multiple challenges such as data barriers, technology transformation, collaborative mechanism and ethical regulation. In the future, it needs to rely on multidisciplinary collaboration and cross sectoral linkage to provide theoretical basis and practical direction for the early prevention and control of cardiovascular health in children and adolescents.
