出生缺陷地理风险因子的空间分析

出生缺陷是影响人口出生质量最重要的因素。大量研究表明,出生缺陷仅仅靠单纯的生物医学研究还不够,多学科的交叉研究是有效探讨出生缺陷病因和预防的唯一出路。利用北京大学人口环境健康组调查数据,分类了能够在地理空间上归属的出生缺陷风险因素,将这些因素存在的空间相关性进行了传统统计分析方法不适宜的风险因子与出生缺陷统计因果之间的研究。探讨了空间分析技术在出生缺陷的地理风险因子研究的一般步骤与关键技术,为出生缺陷研究提供了新的思路。

Spatial Analysis on Geographical Risk Factors of Birth Defects

Birth defect is one of the key elements that seriously affect the quality of population. It is also the important study area in health population. According to references, not only medical analysis, but multi-disciplines researches are needed more on birth defects thoroughly. Geographical risk factors to birth defects refer to risk factors which have common character of spatial attribution to birth defects. Those spatial attributions on those risk factors indicate the classical analysis methods are unsuitable as them founded on samples independence. Spatial analysis deal with spatial association and correlation and have the ability to analyze the statistical consequences of the birth defects and risk factors. Routine and key techniques were presented in this paper for application of spatial analysis on birth defects as well as foreground and limitation.
