Advancing community water fluoridation (CWF) coverage is a national health objective. The Centers for Disease Control and Prevention began adjusting state-reported data to calculate CWF coverage in 2012, and then modified methods in 2016. We evaluate improvements attributable to data adjustment and implications for interpreting trends.
To assess adjustment, we compared the percentage deviation of state-reported data and data adjusted by both methods to the standard estimated by the U.S. Geological Survey. To assess effects on estimated CWF trends, we compared statistics calculated with data adjusted by each method.
The 2016 method outperformed on all points of evaluation. The CWF national objective measure (percentage of community water system population receiving fluoridated water) was negligibly affected by method. Percentage of US population receiving fluoridated water was lower with the 2016 method versus the 2012.
Adjustment of state-reported data improved overall quality of CWF coverage measures and had minimal impact on key measures.
推进社区水氟化（CWF）的覆盖范围是国家卫生目标之一。疾病预防控制中心从 2012 年开始调整各州报告的数据以计算 CWF 的覆盖范围，然后在 2016 年修改了方法。我们评估了数据调整的改进之处及其对解释趋势的影响。
为了评估调整，我们比较了州报告数据以及两种方法调整后的数据与美国地质调查局估计的标准之间的百分比偏差。为了评估对估计的 CWF 趋势的影响，我们比较了用每种方法调整的数据计算的统计数据。
2016 年的方法在所有评估点上都表现出色。CWF 的国家目标衡量标准（接受氟化水的社区水系统人口百分比）受方法的影响可以忽略不计。与 2012 年相比，2016 年接受氟化水的美国人口比例更低。
对州报告数据的调整提高了 CWF 覆盖范围衡量标准的整体质量，对关键措施的影响最小。
