目的综合评价濮阳市2006~2013年碘盐监测结果,为今后碘缺乏病防治工作提供决策依据。方法选取碘盐监测结果的4项统计指标,包括非碘盐率、碘盐合格率、碘盐覆盖率和合格碘盐食用率,运用秩和比法进行综合评价。结果濮阳市2006~2013年的碘盐监测结果根据指标RSR值的分布进行分档排序,并对差、中、优3档RSR平均数进行单因素方差分析,比较差异有统计学意义(F=10.401,P<0.05),进一步LSD检验表明各档均数两两之间的差异均具有统计学意义(P<0.05),其最优的年份是2010年、2011年,居中等的年份是2008年、2012年、2009年、2013年,较差的年份是2006年、2007年。结论运用秩和比法对碘盐监测结果进行综合评价,结果科学、直观,效果较好。
Objective To comprehensively evaluate the results of iodized salt monitoring in Puyang city from 2006 to 2013, and provide the basis for future decision-making on iodine deficiency disorders prevention and treatment. Methods Four statistical indexes of iodized salt monitoring results, including non-iodized salt rate, iodized salt rate, iodized salt coverage rate and qualified iodized salt rate, were selected for comprehensive evaluation by rank sum method. Results The monitoring results of iodized salt in Puyang from 2006 to 2013 were sorted according to the distribution of RSR values. One-way ANOVA was used to analyze the average RSR of the three grades of poor, moderate and excellent grades. The difference was statistically significant (F = 10.401, P <0.05). Further LSD test showed that there was a significant difference between the mean of every file (P <0.05), and the optimal year was 2010, 2011 and middle year was 2008 Year, 2012, 2009, 2013, the worst years are 2006, 2007. Conclusion The rank sum ratio method is used to evaluate the iodized salt monitoring results comprehensively. The results are scientific, intuitive and effective.
