| 本文应用"个体内"相关系数和Kendall相关系数作为估计定量数据和等级数据可靠度的指标,评价太湖。岳西中学学生血压流行病学研究数据的质量。结果表明,在定量数据中,体重、身高的可靠度最高(0.992-0.996),实验室数据次之(0.86~0.96),血压较低(SBP0.77~0.79;DBPⅣ0.72~0.76;DBPV0.29)。在等级数据中,父母文化水平可靠度较高(0.94~0.98),家庭经济收入次之(0.61),精神行为因素较低(0.29~0.45)。本文建议医学研究论文中除应报告实验设计和观察方法之外,还有必要评价研究数据的质量。 |
| English Abstract: |
| Measurement error and reliability of epidemiologic data in two middle schools in Taihu and Yuexi counties have been studied, in which intra-Person standard deviation was used to estimate measurement error and intra-person correlation coefficient relia-, bility respectively. In qualitative data, those of weight and height showed greatest reliability(0.992 for weight, 0.996 for height), followed by laboratory variables (0.86-0.96), and BP variables came last (0.77-0.79 for SBP, 0.72-0.76 for DBP△, 0.29 DBP▽).Among ranked data,those of the education level of the parents were highest (0.94-0.98) psychological and behavioral variables lowest (0.29-0.45), with family income in between (0.61). Accordingly, it is suggested that the quality of data should be estimated in research papers besides presentation of the design and methods of study. |
