背景 自评健康是一种常用的健康状况衡量标准，通常有三到五个类别。该衡量标准通常被分解为健康状况良好与较差的二分变量。这种分类尚未得到证实。 方法 使用 1958 年英国出生队列的数据，我们研究了社会经济状况（以四个年龄段的职业类别表示）与自我评价健康状况之间的关系。将使用逻辑回归获得的二分变量结果与有序钙类别变量的替代方法（包括多元回归、累积比值、连续比和相邻类别模型）进行比较。结果和结论逻辑回归模型得出的有关社会经济地位和自评健康之间关系的发现得到了纳入自评健康有序性质的替代统计方法的证实。在主效应的大小和显着性、关联类型和交互效应方面发现了相似的结果。
Background Self-rated health is a commonly used measure of health status, usually having three to five categories. The measure is often collapsed into a dichotomous variable of good versus less than good health. This categorization has not yet been justified.Methods Using data from the 1958 British birth cohort, we examined the relationship between socioeconomic conditions, indicated by occupational class at four ages, and self-rated health. Results obtained for a dichotomous variable using logistic regression were compared with alternative methods for ordered categorical variables including polytomous regression, cumulative odds, continuation ratio and adjacent categories models.Results and Conclusions Findings concerning the relationship between socioeconomic position and self-rated health yielded by a logistic regression model were confirmed by alternative statistical methods which incorporate the ordered nature of self-rated health. Similarity of results was found regarding size and significance of main effects, type of association and interactive effects.
