Studies of the relationship between hysterectomy use and sociodemographic factors tend to use self-reported data. In the current study, data were collected from a representative sample of US women who have been prospectively followed since 1971. Hysterectomy status was obtained by self-report and from hospital records. Although these two measures of hysterectomy were highly related, more women reported hysterectomy than could be confirmed by hospital records. The two measures showed similar associations between several obstetric and demographic characteristics and hysterectomy status, suggesting that the use of self-reported hysterectomy data does not bias analyses of potentially associated factors.
关于子宫切除术的使用与社会人口学因素之间关系的研究往往采用自我报告的数据。在本研究中，数据收集自1971年起就被前瞻性跟踪的美国女性代表性样本。子宫切除术状态通过自我报告以及医院记录获得。尽管这两种子宫切除术测量方法高度相关，但报告子宫切除术的女性多于医院记录能够证实的人数。这两种测量方法在若干产科和人口统计学特征与子宫切除术状态之间显示出相似的关联，表明使用自我报告的子宫切除术数据不会使对潜在相关因素的分析产生偏差。
