Abstract

OBJECTIVES

This study investigates the data suppression or statistical disclosure limitation (DL) practices used during surveillance data Release by sexually transmitted disease (STD) prevention programs.

METHODS

We classified DL strategies from a Web-based data query system that collected data from state health departments. We tested mean STD incidence Rates in states that used data suppression versus those that did not.

RESULTS

Five types of DL were identified: no suppression (n = 15), numerator-only (n = 10), denominator-only (n = 6), demographic-only (n = 7), and mixed strategies (n = 12). Twenty-two states (62%) used data suppression strategies differently through time. Chlamydia, gonorrhea, and syphilis Rates were higher in the nonsuppression states than those of the suppression states (P = .03, P = .008, P = .009, Respectively).

CONCLUSIONS

Cell suppression is the preferred method of DL used by STD prevention programs. More Research is needed to evaluate the effectiveness of this strategy as a means of balancing the public health utility of the data tables and the protection of confidentiality.

摘要

目的

本研究调查性传播疾病（STD）预防项目在监测数据发布过程中所采用的数据抑制或统计披露限制（DL）做法。

方法

我们对一个从各州卫生部门收集数据的基于网络的数据查询系统中的DL策略进行了分类。我们对采用数据抑制的州和未采用数据抑制的州的STD平均发病率进行了测试。

结果

确定了五种类型的DL：无抑制（n = 15）、仅分子抑制（n = 10）、仅分母抑制（n = 6）、仅人口统计学抑制（n = 7）和混合策略（n = 12）。22个州（62%）在不同时间采用了不同的数据抑制策略。衣原体、淋病和梅毒发病率在未抑制州高于抑制州（分别为P = 0.03、P = 0.008、P = 0.009）。
