Abstract

A logistic model was used to analyse questionnaire return in a postal survey of 311 coalminers who had left their place of employment between 1977 and 1982. Three measures of respiratory health, obstruction, restriction, and presence of chronic bronchitis symptoms, were included in the model as predictors together with the possibly confounding factors of age, education, and marital and smoking status. Age was positively associated with questionnaire return (p less than 0.001). Speed of return, and whether the return was in response to a prompt, were not predicted by either the respiratory health measures or any of the other possibly confounding variables.

摘要

采用逻辑模型分析了对311名在1977年至1982年间离职的煤矿工人进行的邮寄调查中的问卷回复情况。该模型纳入了三项呼吸健康指标,即阻塞、受限和慢性支气管炎症状的存在情况作为预测因素,同时纳入了年龄、教育程度、婚姻状况和吸烟状况等可能的混杂因素。年龄与问卷回复呈正相关(p<0.001)。呼吸健康指标或任何其他可能的混杂变量均无法预测回复速度以及回复是否是对提示的响应。
