STD染病率与族裔、年龄的相关性分析

Statistical Analysis of Three Sexually Transmitted Diseases in US by Race and Age

STD是三种性传播疾病衣原体病、淋病和梅毒的简称.以统计学方法分析,发现其染病率与族裔、年龄均有关系,其中衣原体病的染病率较高,年龄是最重要因素.而族裔因素较为复杂,当把不同族裔分别作为变量进行统计时,族裔及年龄与族裔的交互作用均为重要因素;族裔被分为两个组群作为两个变量进行统计时,族裔及年龄与族裔的交互作用则为非重要因素.因此,关于族裔对STD染病率的影响,应作为单独项目收集更多数据做进一步分析.
