世界健康调查—中国调查数据分析方法

Data analysis method in world health survey-China survey

摘要

摘要:
目的对世界健康调查中的调查数据进行分析, 以获得卫生系统总体绩效的合理评估。
方法用抽样权重作为调整值, 采用Taylor级数线性化技术估计总体参数及相应的方差。
结果对于健康状况指标和卫生系统反应性指标的排序, 几个抽样点通过普通统计方法和调查数据分析方法所获得的结果间存在明显差异。采用来自于调查数据分析方法的结果去建立对抽样地区的综合绩效评估。
结论多阶段抽样设计使得抽样调查的分析变得复杂, 调查数据分析方法可以计算总体参数的点估计和方差估计的近似值, 这种方法减少了由于背离独立同分布(independent and identical distribution, IID)假设所产生的偏倚。

Abstract:
Objective To analyz the survey data in world health survey and obtain reasonable estimation of health system performance for population.
Methods Sampling weights were used as adjustments, and the Taylor series linearization technique was used to estimate the population parameter and associated variances.
Results Of the ranks of health status indicators and health system responsiveness indicators, there were significant difference between the resutls of the common statistical method and of survey data analysis method for several sampled sites.
Results derived from survey data analysis method was used to construct the comprehensive performance evaluation for sampled areas.
Conclusion The multistage sample design introduced a complexity to the analysis of sample survey, and the survey data analysis method can compute approximations of point estimate and variance estimate of an population parameter, which reduced the bias associated with the deviation from independent and identical distribution(IID)assumption.
