三聚氰胺污染奶粉致泌尿系结石的logistic回归分析

【摘要】 目的 通过对三聚氰胺污染奶粉致泌尿系结石的流行病学调查，探讨该病发生的危 险因素，为预防该病提供比较可靠的依据。方法 采用1:2配对病例对照研究，26例三聚氰 胺污染奶粉致泌尿系结石患儿为研究对象，以性别为匹配因素，且年龄相差不超过1岁的三 聚氰胺非泌尿系结石者为对照组。自制调查问卷，进行单因素及多因素条件logistic回归分 析。结果 一级亲属泌尿系结石史、婴儿期污染奶粉喂养史及服用钙剂OR值分别为12.321、 6.792、3.454，饮水OR值为0.359。结论　一级亲属泌尿系结石史、婴儿期污染奶粉喂养史、 及服用钙剂为危险因素，饮水为保护因素。

Logistic Regression Analysis Findings of the Urinary Calculus Caused by Melamine - Contaminated Milk Powder

【Abstract】Objective Through epidemiological Investigation of the urinary calculus caused by melamine-contaminated milk powder, to explore the risk factors of the disease and provide a reliable basis for preventing the disease’s incidence.Methods A 1:2 matched case control study was conducted to investigate 26 cases and 52 the control, the cases were urinary calculus result from melamine-contaminated milk powder, the control has’t have urinary calculus caused by melamine-contaminated milk powder, matching factor with sex, and the different of age less than or equal to one year. The data were analyzed for Single and Multiple factor conditional logistic regression. Results The results of OR : the history of urinary lithiasis with the first degree relative(12.321) , infancy fed with melamine-contaminated milk powder (6.792), take calcium (3.454), drink water(0.359).Conclusion The results of multiple regression model showed that the risk factors of this disease were the history of urinary lithiasis with the first degree relative, infancy fed with melamine - contaminated milk powder and take calcium,the protective factor was to drink water.
