摘要
目的通过多重对应分析探讨已婚育龄妇女所选择的避孕措施与其社会人口学特征的关联关系。方法运用SAS9.1对应分析过程对某生殖健康项目基线研究中育龄妇女的避孕措施有关数据进行多重对应分析,并探索变量分组组合对降维效果的优化。结果通过变量分组组合进行多重对应分析提高了前两个公因子的累计贡献率,优化了降维效果,使研究结果更可靠;图示结果显示有一个孩子者与使用宫内节育器、有两个及以上孩子者与使用节育手术有相对较强的关联,城市户籍者与避孕套的使用有关联。结论变量分组组合的多重对应分析在探索多维列联表变量间关联关系时有良好的效果。长期的计划生育政策导向对已婚妇女避孕行为产生了重大的影响。
Objective To study the correlation between contraceptive methods and demographic characteristic among married women by multiple correspondence analysis.Methods The data of women＇s contraceptive methods from the baseline survey in a reproductive health project were processed by SAS9.1.Subgroup analysis and combinations of variables were applied to improve dimension reduction results of multiple correspondence analysis.Results Cumulative contribution of the first two factors increased through subgroup analysis and combinations of variables,and better results of dimension reduction were got.The statistic charts showed the strong correlation between number of children and contraceptive practices,women who had one child tended to use IUD and women who had two or more children tended to use sterilization.Condom use was related to urban residence.Conclusion Application of subgroup analysis and variables combinations on multiple correspondence analysis was beneficial to correlation analysis of categorical variables from multidimensional contingency table.Long-term family planning policy had a significant impact on contraceptive practices.
