一、项目介绍

随着中国老龄化进程加速，国家统计局数据显示，截至2022年底，我国60岁及以上人口已达2.8亿，占总人口的19.8%，预计到2035年将突破4亿，占比超过30%。面对如此庞大的老年群体，其健康状况直接关系到社会医疗资源分配和国家养老政策制定。传统老年健康数据分析方法难以应对海量、多维、异构的健康数据，难以挖掘深层次的健康规律和趋势。而大数据技术的发展为解决这一问题提供了新思路。卫健委《"健康中国2030"规划纲要》明确提出要"推进健康医疗大数据应用"，建设"覆盖全民的健康信息平台"。在此背景下，开发基于Spark的全国健康老龄化数据分析系统，利用Hadoop、Spark等大数据技术，结合Python、Django、Vue和Echarts等开发工具，构建全面的老年健康数据分析平台，对促进健康老龄化具有重要意义。

本系统的开发具有多方面的现实意义。在医疗资源优化方面，通过分析老年人就医频率与健康状况的关系，能够帮助医疗机构更合理地配置资源，减少浪费，提高服务效率。对政策制定而言，系统提供的老年人健康风险聚类分析结果，可为分层分类的老年健康政策提供数据支持，使政策更具针对性。从预防医学角度看，系统能够识别高风险老年群体的特征，为早期干预提供依据，降低疾病发生率。对老年人自身来说，系统生成的多维健康评分可以增强健康自我管理意识，改善生活质量。技术层面上，该系统将Spark大数据处理与健康老龄化领域深度融合，探索了大数据技术在特定垂直领域的应用模式，为类似系统的开发提供了参考框架。这些价值使得本系统不仅是一个技术实现，更是解决社会现实问题的有效工具。
